PIR深冷绝热系统中对防潮层的技术要求

PIR深冷绝热系统中对防潮层（Vapour Barrier）的技术要求说明：由于PIR材料防潮指标较低，因此需要质量较好的防潮层系统。

国产的玛褅脂类的防潮层材料，一般为重油沥青等原料炼制而成，干化后弹性不好，容易开裂。

抗老化性能也较差。

因此对于LNG深冷项目不适宜采用。

对于大型的LNG深冷工程一般采用的防潮层系统产品有如下要求。

1、主防潮层:主防潮层使用两层涂敷的弹性树脂材料，其干膜厚度如下列所示，材料必须包含30%比重的氯磺化聚乙烯并且在预期环境温度下保持弹性。

防潮层需要与保冷材料相兼容，且能防紫外线。

同时具有以下特性(a) 最小干膜厚度: 1.20mm.(b) 适用温度: - 40°C 到80°C.(c) 火苗蔓延速度: 20.0 根据ASTM E.84(d) 水蒸气穿透速率: 0.02 Perm干膜厚度0.75，按ASTM E96，程序E 测试(e) 阻燃性：离火1 秒自熄(f) 吸水率：<0.5%(试料重量)(g) 颜色: 白，灰或铝白色推荐产品：FOSTER 60-90/912、次防潮层多层膜（两层聚酯膜夹一层铝箔）用作第二防潮层。

所用材料性能如下：a) 工作温度：-60℃~+70℃b) 渗透性（根据ASTM E96，步骤B）：≤0.001g/h/m2（水平方向）c) 厚度：聚酯膜≥12um（每层）铝箔≥25um总厚度≥50um推荐产品：Armachek S350注：1）聚酯多层膜在预制阶段就应覆盖在管子和管件上。

100mm 宽的带材用于自粘聚酯多层膜的现场连接。

2）对于管件（弯头，三通）：如果预制第二防潮层不能安装，现场安装时改用双面都涂敷丁基橡胶乳液的合成纤维（最小厚度为0.5mm）。

称重法透湿性测试标准ASTM E96概要

称重法透湿性测试标准ASTM E96概要摘要：本文详细介绍了ASTM E 96 的内容，并对于关键测试部分以及关键技术参数给予了详细的介绍。

关键词：称重法，增重法，减重法，透湿杯，测试环境，密封透湿性指标是包装材料的主要性能指标之一。

随着人们对产品防潮、防水重视程度的增加，阻湿性能更优的包装材料（即包装材料的透湿性更小）已经成为包装材料开发和使用的重点，近几年受到越来越多的关注。

包装商、材料供应商、产品制造商以及各检测机构纷纷引进透湿性检测设备，加强对包装材料透湿性能测试的力度。

现在市场上销售的透湿性测试仪的主要有称重法（Cup Method）透湿仪和传感器法透湿仪两大类。

ASTM E 96 是称重法测试标准之一，它不但详细介绍了在其它标准中常见的增重法（Desiccant Method），而且还介绍了在透湿性测试领域中与增重法具有同等地位的减重法（Water Method）。

1、称重法概要称重法是一种独立的透湿性测试方法，测试原理简单明了：在规定的温度、相对湿度下，使试样两侧保持一定的水蒸气压差，测量透过试样的水蒸气量，计算透湿性相关参数。

称重法可以分为渗透进入透湿杯的增重法和渗透离开透湿杯的减重法两种方法，它们的测试原理相同。

蒸汽渗透系数表

蒸汽渗透系数表
蒸汽渗透系数表是一种把蒸汽流体在给定温度下渗透系数表示
的表格，用来表征物质和液体时的蒸汽流体渗透情况。

可以用它来测量蒸汽渗透的速度，从而可以采取不同的措施来提高蒸汽的渗透率。

蒸汽渗透系数表由多种因素影响，其中包括管径、管壁厚度和材料、介质的温度、压力差等因素。

其中，管径和管壁厚度影响蒸汽渗透系数最为明显，由于管径越小，渗透率越低；同样，管壁越厚，渗透率也越低。

而介质的温度和压力差也会影响渗透系数，由于温度越高，渗透速度越快；同样，压力差越大，渗透率越高。

蒸汽渗透系数表里大多数材料的渗透系数都在0.1至3.0之间，从而可以结合现场实际情况来设置合适的渗透系数。

而且，小型管比大型管的渗透系数要高得多，这也造成了小型管的渗透效率更高，也更加经济实惠。

除了温度和压力差影响蒸汽渗透系数外，还有其他一些因素也会对蒸汽流体渗透有影响，比如蒸汽流体的浓度、介质的黏度等，都会影响渗透系数。

例如，渗透系数越小，说明浓度增加了，此时渗透率也会降低。

蒸汽渗透系数表的应用也极其重要，通过精确的渗透系数分析，可以帮助企业准确的增加蒸汽的热效率，有助于企业经济效益的提高，同时也有助于减少工艺设备中的能量损失。

蒸汽渗透系数表是影响蒸汽渗透效率的重要依据，只有精确的渗透系数表，才能保证蒸汽渗透系统运行的正常，实现充分利用。

因此，
建立准确的蒸汽渗透系数表是提高蒸汽流体渗透率的重要步骤，同时也是企业进行节能的重要依据之一。

through the specimen from the water to the controlled atmo-sphere.The vapor pressure difference is nominally the same inboth methods except in the variation,with extremes of humid-ity on opposite sides.5.Signiﬁcance and Use5.1The purpose of these tests is to obtain,by means ofsimple apparatus,reliable values of water vapor transferthrough permeable and semipermeable materials,expressed insuitable units.These values are for use in design,manufacture,and marketing.A permeance value obtained under one set oftest conditions may not indicate the value under a different setof conditions.For this reason,the test conditions should beselected that most closely approach the conditions of use.While any set of conditions may be used and those conditionsreported,standard conditions that have been useful are shownin Appendix X1.6.Apparatus6.1Test Dish—The test dish shall be of any noncorrodingmaterial,impermeable to water or water vapor.It may be ofany shape.Light weight is desirable.A large,shallow dish ispreferred,but its size and weight are limited when an analyticalbalance is chosen to detect small weight changes.The mouth ofthe dish shall be as large as practical and at least4.65in.2(3000mm2x).The desiccant or water area shall be not less than themouth area except if a grid is used,as provided in12.1,itseffective area shall not exceed10%of the mouth area.Anexternalﬂange or ledge around the mouth,to which thespecimen may be attached,is useful when shrinking or warpingoccurs.When the specimen area is larger than the mouth area,this overlay upon the ledge is a source of error,particularly forthick specimens.This overlay material should be masked asdescribed in10.1so that the mouth area deﬁnes the test area.The overlay material results in a positive error,indicatingexcessive water vapor transmission.The magnitude of the erroris a complex function of the thickness,ledge width,moutharea,and possibly the permeability.This error is discussed byJoy and Wilson.6This type of error should be limited to about10to12%.For a thick specimen the ledge should not exceed 3⁄4in.(19mm)for a10-in.(254-mm)or larger mouth(square or circular)or1⁄8in.(3mm)for a5-in.(127-mm)mouth(squareor circular).For a3-in.(76-mm)mouth(square or circular)theledge should not exceed0.11in.(2.8mm)wide.An allowableledge may be interpolated for intermediate sizes or calculatedaccording to Joy and Wilson.6A rim around the ledge(Fig.X1.1)may be useful.If a rim is provided,it shall be not morethan1⁄4in.(6mm)higher than the specimen as attached.Different depths may be used for the Desiccant Method andWater Method,but a3⁄4-in.(19-mm)depth(below the mouth)is satisfactory for either method.6.2Test Chamber—The room or cabinet where the as-sembled test dishes are to be placed shall have a controlledtemperature and relative humidity.The temperature chosen shall be between21and32°C(70and90°F),and shall be maintained constant within61°C(62°F).A temperature of 32°C(90°F)is recommended(Note1).The relative humidity shall be maintained at5062%,(When extremes of humidi-ties are desired,the temperature shall be3861°C(1006 1.8°F)The relative humidity shall be9062%.Both temperature and relative humidity shall be measured fre-quently7,or preferably recorded continuously.Air shall be continuously circulated throughout the chamber,with a veloc-ity sufficient to maintain uniform conditions at all test loca-tions.The air velocity over the specimen shall be between0.02 and0.3m-s-1(0.066and1ft/s).Suitable racks shall be provided on which to place the test dishes within the test chamber.N OTE1—Simple temperature control by heating alone is usually made possible at32°C(90°F).However,it is very desirable to enter the controlled space,and a comfortable temperature is more satisfactory for that arrangement.Temperatures of23°C(73.4°F)and26.7°C(80°F)are in use and are satisfactory for this purpose.With cyclic control,the average test temperature may be obtained from a sensitive thermometer in a mass of dry sand.The temperature of the chamber walls facing a specimen over water should not be cooler than the water to avoid condensation on the test specimen.6.3Balance and Weights—The balance shall be sensitive toa change smaller than1%of the weight change during the period when a steady state is considered to exist.The weights used shall be accurate to1%of the weight change during the steady-state period.For example:-perm (5.7310−11kg·Pa−1·s−1·m−2)specimen10in.(254mm)square at80°F(26.7°C)passes8.6grains or0.56g/day.In18days of steady state,the transfer is10g.For this usage,the balance must have a sensitivity of1%of10g or0.1g and the weights must be accurate to0.1g.If,however,the balance has a sensitivity of0.2g or the weights are no better than0.2g,the requirements of this paragraph can be met by continuing the steady state for36days.An analytical balance that is much more sensitive will permit more rapid results on specimens below1perm(5.7310−11kg·Pa−1·s−1·m−2)when the as-sembled dish is not excessively heavy.A light wire sling may be substituted for the usual pan to accommodate a larger and heavier load.7.Materials7.1Desiccant and Water:7.1.1For the Desiccant Method,anhydrous calcium chlo-ride in the form of small lumps that will pass a No.8 (2.36-mm)sieve,and free ofﬁnes that will pass a No.30 (600-µm)sieve,shall be used(Note2).It shall be dried at 400°F(200°C)before use.N OTE2—If CaCl2will react chemically on the specimen,an adsorbing desiccant such as silica gel,activated at400°F(200°C),may be used;but the moisture gain by this desiccant during the test must be limited to4%.7.1.2For the Water Method,distilled water shall be used in the test dish.7.2Sealant—The sealant used for attaching the specimen to the dish,in order to be suitable for this purpose,must be highly6Joy, F.A.,and Wilson,H.G.,“Standardization of the Dish Method forMeasuring Water Vapor Transmissions,”National Research Council of Canada, Research Paper279,January1966,p.263.7The minimum acceptable is to preform this measurement each time the sample isweighed.resistant to the passage of water vapor(and water).It must not lose weight to,or gain weight from,the atmosphere in an amount,over the required period of time,that would affect the test result by more than2%.It must not affect the vapor pressure in a water-ﬁlled dish.Molten asphalt or wax is required for permeance tests below4perms (2.3310−10kg·Pa−1·s−1·m−2).Sealing methods are discussed in Appendix X2.8.Sampling8.1The material shall be sampled in accordance with standard methods of sampling applicable to the material under test.The sample shall be of uniform thickness.If the material is of nonsymmetrical construction,the two faces shall be designated by distinguishing marks(for example,on a one-side-coated sample,“I”for the coated side and“II”for the uncoated side).9.Test Specimens9.1Test specimens shall be representative of the material tested.When a product is designed for use in only one position, three specimens shall be tested by the same method with the vaporﬂow in the designated direction.When the sides of a product are indistinguishable,three specimens shall be tested by the same method.When the sides of a product are different and either side may face the vapor source,four specimens shall be tested by the same method,two being tested with the vapor ﬂow in each direction and so reported.9.2A slab,produced and used as a laminate(such as a foamed plastic with natural“skins”)may be tested in the thickness of use.Alternatively,it may be sliced into two or more sheets,each being separately tested and so reported as provided in9.4,provided also,that the“overlay upon the cup ledge”(6.1)of any laminate shall not exceed1⁄8in.(3mm).9.3When the material as used has a pitted or textured surface,the tested thickness shall be that of use.When it is homogeneous,however,a thinner slice of the slab may be tested as provided in9.4.9.4In either case(9.2or9.3),the tested overall thickness,if less than that of use,shall be at leastﬁve times the sum of the maximum pit depths in both its faces,and its tested permeance shall be not greater than5perms(3.3metric perms).9.5The overall thickness of each specimen shall be mea-sured at the center of each quadrant and the results averaged. Measurement of specimens of0.125in.or less in thickness shall be made to the nearest0.0001in.Measurement of specimens greater than0.125in.in thickness shall be made to the nearest0.001in.9.6When testing any material with a permeance less than 0.05perms or when testing a low permeance material that may be expected to lose or gain weight throughout the test(because of evaporation or oxidation),it is strongly recommended that an additional specimen,or“dummy,”be tested exactly like the others,except that no desiccant or water is put in the dish. Failure to use this dummy specimen to establish modiﬁed dish weights may signiﬁcantly increase the time required to com-plete the test.Because time to reach equilibrium of water permeance increases as the square of thickness,thick,particu-larly hygroscopic,materials may take as long as60days to reach equilibrium conditions.10.Attachment of Specimen to Test Dish10.1Attach the specimen to the dish by sealing(and clamping if desired)in such a manner that the dish mouth deﬁnes the area of the specimen exposed to the vapor pressure in the dish.If necessary,mask the specimen top surface, exposed to conditioned air so that its exposure duplicates the mouth shape and size and is directly above it.A template is recommended for locating the mask.Thoroughly seal the edges of the specimen to prevent the passage of vapor into,or out of, or around the specimen edges or any portion thereof.The same assurance must apply to any part of the specimen faces outside their deﬁned areas.Suggested methods of attachment are described in Appendix X2.N OTE3—In order to minimize the risk of condensation on the interior surface of the sample when it is placed in the chamber,the temperature of the water prior to preparation of the test specimen should be within62°F (61.1°C)of the test condition.11.Procedure for Desiccant Method11.1Fill the test dish with desiccant within1⁄4in.(6mm)of the specimen.Leave enough space so that shaking of the dish, which must be done at each weighing,will mix the desiccant.11.2Attach the specimen to the dish(see10.1)and place it in the controlled chamber,specimen up,weighing it at once. (This weight may be helpful to an understanding of the initial moisture in the specimen.)11.3Weigh the dish assembly periodically,often enough to provide eight or ten data points during the test.A data point is the weight at a particular time.The time that the weight is made should be recorded to a precision of approximately1%of the time span between successive weighing.Thus,if weighings are made every hour,record the time to the nearest30s;if recordings are made every day,a time to the nearest15min would be allowed.Atﬁrst the weight may change rapidly;later a steady state will be reached where the rate of change is substantially constant.Weighings should be accomplished without removal of the test dishes from the controlled atmo-sphere,but if removal is prescribed necessary,the time the specimens are kept at different conditions,temperature or relative humidity,or both,should be kept to a minimum.When results of water vapor transmission are expected to be less than .05perm,a dummy specimen is strongly recommended.Such a dummy specimen should be attached to an empty cup in the normal manner.The environmental effects of temperature variation and buoyancy variability due to barometric pressure ﬂuctuation can be arithmetically tared out of the weighing values.This precaution permits earlier and more reliable achievement of equilibrium conditions.Analyze the results as prescribed in13.1.11.4Terminate the test or change the desiccant before the water added to the desiccant exceeds10%of its starting weight(Note1and Note3).This limit cannot be exactly determined and judgement is required.The desiccant gain may be more or less than the dish weight-gain when the moisture content of the specimen has changed.N OTE4—The WVT of some materials(especially wood)may depend on the ambient relative humidity immediately before the test.Anapparenthysteresis results in higher WVT if the prior relative humidity was above the test condition and vice versa.It is therefore recommended that specimens of wood and paper products be conditioned to constant weight in a50%relative humidity atmosphere before they are tested.Some specimens may be advantageously preconditioned to minimize the mois-ture that the specimen will give up to the desiccant.This applies when the specimen is likely to have high moisture content or when it is coated on the top(vapor source)side.12.Procedure for Water Method12.1Fill the test dish with distilled water to a level3⁄461⁄4 in.(1966mm)from the specimen.The air space thus allowed has a small vapor resistance,but it is necessary in order to reduce the risk of water touching the specimen when the dish is handled.Such contact invalidates a test on some materials such as paper,wood,or other hygroscopic materials.The water depth shall be not less than1⁄8in.(3mm)to ensure coverage of the dish bottom throughout the test.However,if the dish is of glass,its bottom must be visibly covered at all times but no speciﬁc depth is required.Water surges may be reduced in placing a grid of light noncorroding material in the dish to break the water surface.This grid shall be at least1⁄4in.(6mm) below the specimen,and it shall not reduce the water surface by more than10%(Note4).N OTE5—For the Water Method,baking the empty dish and promptly coating its mouth with sealant before assembly is recommended.The water may be added most conveniently after the specimen is attached, through a small sealable hole in the dish above the water line.12.2Attach the specimen to the dish(see10.1).Some specimens are likely to warp and break the seal during the test. The risk is reduced by preconditioning the specimen,and by clamping it to the dish ledge(if one is provided).12.3Weigh the dish assembly and place it in the controlled chamber on a true horizontal surface.Follow the procedure given in11.3.If the test specimen cannot tolerate condensation on the surface,the dish assembly shall not be exposed to a temperature that differs by more than5°F(2.8°C)from the control atmosphere to minimize the risk of condensation on the specimen.When results of water vapor transmission are expected to be less than.05perm,a dummy specimen is strongly recommended.Such a dummy specimen should be attached to an empty cup in the normal manner.The environ-ment effects of temperature variation and buoyancy variability due to barometric pressureﬂuctuation can be arithmetically tared out of the weighing values.This precaution permits earlier and more reliable achievement of equilibrium condi-tions.Analyze the results as prescribed in13.1.12.4Where water is expected to be in contact with the barrier in service,proceed as in11.3except place the dish in an inverted position.The dish must be sufficiently level so that water covers the inner surface of the specimen despite any distortion of the specimen due to the weight of the water.With highly permeable specimens it is especially important to locate the test dish so that air circulates over the exposed surface at the speciﬁed velocity.The test dishes may be placed on the balance in the upright position for weighing,but the period during which the wetted surface of the specimen is not covered with water must be kept to a minimum.13.Calculation and Analysis of Results13.1The results of the rate of water vapor transmission may be determined either graphically or numerically.13.1.1Dummy Specimen—If a dummy specimen has been used to compensate for variability in test conditions,due to temperature or barometric pressure,or both,the daily recorded weights can be adjusted by calculating the weight change from initial to time of weighing.This adjustment is made by reversing the direction of the dummy’s weight change,relative to its initial weight,and modifying all the appropriate specimen weight(s)recorded at this time.This permits earlier achieve-ment of equilibrium conditions.An alternate procedure,par-ticulary for tests of long duration and more than six weighings, is to subtract the arithmetic mean slope of the rate of weight change of the dummy specimen from the arithmetic mean slope of each similar specimen to get an effective rate of weight change.These procedures are also desirable if the specimen is changing weight due to a curing process while under test. 13.1.2Graphic Analysis—Plot the weight,modiﬁed by the dummy specimen when used,against elapsed time,and in-scribe a curve which tends to become straight.Judgment here is required and numerous points are helpful.When a straight line adequatelyﬁts the plot of at least six properly spaced points(periodic weight changes matching,or exceeding20% of the multiple of100times the scale sensitivity),a nominally steady state is assumed,and the slope of the straight line is the rate of water vapor transmission.13.1.3Numerical Analysis—A mathematical least squares regression analysis of the weight,modiﬁed by the dummy specimen when used,as a function of time will give the rate of water vapor transmission.An uncertainty,or standard deviation of this rate,can also be calculated to deﬁne the conﬁdence band.For very low permeability materials,this method can be used to determine the results after30to60days when using an analytical balance,with a sensitivity of61mg,even if the weight change does not meet the100times the sensitivity requirement of6.3.Specimens analyzed in this manner must be clearly identiﬁed in the report.13.2Calculate the water vapor transmission,WVT,and permeance as follows:13.2.1Water Vapor Transmission:WVT5G/tA5~G/t!/A(1) where:In inch-pound units:G=weight change,grains(from the straight line),t=time during which G occurred,h,G/t=slope of the straight line,grains/h,A=test area(cup mouth area),ft2,andWVT=rate of water vapor

desiccant method;in the dish forwater method),andR2=relative humidity at the vapor sink expressed as a fraction.13.2.3In the controlled chamber the relative humidity and temperature are the average values actually measured during the test and(unless continuously recorded)these measurements shall be made as frequently as the weight measurements.In the dish the relative humidity is nominally0%for the desiccant and100%for the water.These values are usually within3% relative humidity of the actual relative humidity for specimens below4perms(2.3310−7g·Pa−1·s−1·m−2)when the required conditions are maintained(no more than10%moisture in CaCl2and no more than1in.(25mm)air space above water).13.3Only when the test specimen is homogeneous(not laminated)and not less than1⁄2in.(12.5mm)thick,calculate its average permeability(perm in.)(metric perm-cm)as follows: Average permeability5permeance3thickness(3) N OTE6—Example:In a desiccant test that ran288h(12days)on an exposed area

(wet)in pan.Press specimen in place.Avoid squeezing compoundinto the test area.X1.4.2.3Step 3—Coat outside of rim and bottom of ledgewith contact bond cement,and place foil strips from edge oftemplate,around rim,and bottom of ledge.X1.5A method of using hot asphalt,as applied to a 10-in.(254-mm)square-mouth dish with ledge and rim,is as follows:X1.5.1Apparatus :X1.5.1.1Template —A square frame of brass or steel,3⁄16in.(5mm)thick and 3⁄4in.(19mm)deep.The 3⁄16-in.(5-mm)thickness is tapered to zero at the bottom of the frame where itwill touch the test specimen and maintain a 10-in.(254-mm)square test area.X1.5.1.2Sealant —Asphalt (see X1.3.1used at the proper pouring consistency of 375to 450°F (179to 232°C).X1.5.1.3Melting Pot for the asphalt,electrically heated,with one dimension greater than 113⁄8in.(289mm).X1.5.1.4Small Ladle for pouring.X1.5.2Procedure —Mark the 113⁄8-in.(289-mm)square specimen with a line at an equal distance from each edge,so that the area enclosed by the lines is as nearly as possible a 10-in.(254-mm)square.The template may be used for marking.Dip each edge of the specimen in molten asphalt up to the line,so that the test area is deﬁned and all edges are coated with a heavy layer of asphalt.Place the specimen over the pan containing water or desiccant.Lightly oil the template or coat with petroleum jelly on its outer side,and place on the specimen.Pour molten asphalt into the space between the template and the rim of the pan.After the asphalt has cooled for a few minutes,the template should be easily removable.X1.6Hot wax may be applied like asphalt.It may also be applied (freely)with a small brush.Its lower working tempera-ture may be advantageous when a specimen contains moisture.X1.7Several designs for dishes with supporting rings and ﬂanges are shown in Fig.X1.2.Various modiﬁcations of these designs may be made provided that the principle of prevention of edge leakage by means of a complete seal is retained.The dishes may be constructed of any rigid,impermeable,corrosion-resistant material,provided that they can be accom-modated on the available analytical balance.A lightweight metal,such as aluminum or one of its alloys,is generally used for larger-size dishes.In some cases when an aluminum dish is employed and moisture is allowed to condense on its surface,there may be appreciable oxidation of the aluminum with a resulting gain in weight.Any gain in weight will ordinarily depend on the previous history of the dish and the cleanness of the surface.An empty dish carried through the test procedure as a control will help to determine whether any error may be expected from this cause.When aluminum dishes are used for the water methods,a pressure may develop inside the assembly10Grade Nos.2305or 2310of the Mobil Oil Corp.,or their equivalent,have beenfound satisfactory for thispurpose.FIG.X1.1Apparatus for Water Vapor Transmission Tests of Large ThickSpecimens。

什么是防水透湿面料？防水透湿面料的英文

什么是防水透湿面料？防水透湿面料的英文什么是防水透湿面料（布料）？防水透湿面料的作用和用途？防水透湿面料的英文衡量防水的指标是每平方毫米承受水压高度mm水柱表示，透气量是以每平方毫米24小时透过水汽的重量来衡量。

防水透湿面料（布料）介绍当你去登山的时候，冷不丁会下雨，总不能撑着雨伞上山吧。

爬山又是一项非常消耗体力的运动，出大量的汗水，而山上的温度一般都很低，总不能把衣服脱掉吧。

那么，怎么样才能一下解决这类问题呢？实际上，人们很早就在研究这个问题了，那就是穿一件既防水又能透湿的衣服。

（平时人们常称它为透气织物，但不是空气中的气体，而是汗水蒸发出来的蒸汽）。

具体来讲，防水透湿织物是指水在一定压力下不浸入织物，而人体散发的汗液却能以水蒸气的形式通过织物传导到外界，从而避免汗液积聚冷凝在体表与织物之间以保持服装的舒适性，它是一种高技术、独具特色的功能性织物。

防水对于普通面料工作者来说并不是什么难题，关键是如何实现透湿。

下面，我们从防水透湿织物的种类来深入了解一下它。

一、通过纤维来实现透湿1、文泰尔织物。

最早的防水透湿织物是著名的文泰尔(Ventile)织物。

它是上世纪40年代由英国的Shirley研究所设计的，选用埃及长绒棉的高支低捻度纯棉纱高密重平组织织物，最初主要用于第二次世界大战期间的英国空军飞行员的防寒抗浸服。

当织物干燥时，经纬纱线间的间隙较大，大约10微米，能提供高度透湿的结构；当雨或水淋织物时，棉纱膨胀，使得纱线间的间隙减至3～4 微米，这一闭孔机制同特殊的拒水整理相结合，保证织物不被雨水进一步渗透。

目前该类面料早已被其它防水透湿面料所取代。

服饰搭配2、Coolmax类面料。

杜邦、日本东丽等国际大公司研究的通过纤维内部制造出孔道的方式实现将汗水排出体外，也就是市场上的吸湿排汗面料。

该类纤维生产技术集中在这类国际大公司手上，价格相对较高，难以成为市场的主流。

二、通过涂层来实现透湿采用干法直接涂层、转移涂层、泡沫涂层、相位倒置或湿法涂层（凝固涂层）等工艺技术，将各种各样具有防水、透湿功能的涂层剂涂敷在织物的表面上，使织物表面孔隙被涂层剂封闭或减小到一定程度，从而得到防水性。

透湿测试方法

透湿测试方法现在的测试方法有多少？访三丰董事长——姚明实录:1、控制杯法1.1 水蒸气透过法1.1.1正杯法A,中国国家标准:GB/T12704-91 BB,美国材料实验协会标准：ASTM E96 Produce B and DC,日本工业标准：JIS L-1099 A2D,加拿大标准：(CGSB)-4.2 No.49-99E,英国标准:BS 7209-19901.1.2倒杯法(也叫吸湿法)A，美国材料实验协会标准：ASTM E96 BW(1995版和2000版)1.2 干燥剂法1.2.1正杯法A，中国国家标准：GB/T 12704-91 AB，日本工业标准：JIS L-1099 A1C，美国材料试验学会标准：ASTM E-96 A、C、E1.2.2倒杯法A，日本工业标准：JIS L-1099 B1、B2B，美国材料试验学会标准：ASTM E-96C，比利时UCB公司标准：UCB 法D，英国标准:B.T.T.G法2、出汗热盘法，也称皮肤模型法A，ISO标准：ISO 11092B，消防防护服测试：NFPA 1971C，美国材料试验学会标准：ASTM F 1868-98 BD，德国标准：DIN 54 010 T01-A3、出汗假人法出汗假人法的假人有点像热盘，用来模拟典型人体的形状和尺寸。

假人测试比出汗热盘测试更具有实际意义，因为它可以考虑更多的变量，包括服装覆盖人体的表面积，纺织品的层数和人体表面空气层的分布，松还是紧配合，人体不同部分的皮肤温度差异，身体的位置和运动状态等。

但是，还没有一个出汗假人可以测试在诸如行走时动态条件下的蒸发热阻力。

当前，还没有出汗假人的设计标准和测试步骤。

而且由于出汗假人更加复杂和昂贵，使得假人测试费用比热盘法高。

4、其它方法（Watkins、Memander等等）真的是太多了，我们还是来具体了解一下几个相对比较有用的方法吧。

1，最常用的方法：ASTM E96 BW，美国材料试验学会标准，水蒸气倒杯法。

防水透湿功能性面料的性能与测试方法

防水透湿功能性面料的性能及试验方法防水透湿面料是指在一定压力下水不会渗入面料，但人体散发的汗液可以通过面料以水蒸气的形式传递到外界，从而避免体表和织物之间的汗水和冷凝水的积累，使衣物保持舒适。

它是一种高科技、独特的功能面料。

防水对普通面料工人来说不是问题，关键是如何做到透湿。

下面，我们就从防水透气面料的种类来深入了解一下。

一、通过纤维实现透湿1. 通风面料。

最早的防水透气面料是著名的Ventile面料。

由英国雪莉研究所于1940年代设计，采用埃及长绒棉的高支低捻纯棉纱，高密度重型平纹织物，最初主要用于英国航空公司二战期间的部队飞行员。

防寒防湿衣。

织物干燥时，经纬纱间隙较大，约10微米，可提供高透湿结构；当织物暴露在雨水或水中时，棉纱会膨胀，从而将纱线之间的间隙缩小到 3 到 4 微米。

这种细胞关闭机制与特殊的防水处理相结合，确保织物不会被雨水进一步渗透。

目前，这类面料已被其他防水透气面料所替代。

2. Coolmax面料。

杜邦、日本东丽等国际大公司研究了通过在纤维部分制造毛孔来排出身体汗水的方法，即市面上的吸湿排汗面料。

这类纤维生产技术集中在这样的国际大公司手中，价格相对较高，难以成为市场主流。

二、通过涂层实现透湿通过干式直接涂层、转移涂层、泡沫涂层、相转化或湿涂层（定型涂层）等工艺技术将各种拒水透湿涂层剂应用于织物。

在织物表面，织物表面的气孔被涂层剂封闭或缩小到一定程度，从而获得防水性。

织物的透湿性是通过涂层上特殊方法形成的微孔结构或涂层剂中的亲水基团与水分子相互作用，借助氢键等分子间作用力，使水分子吸附在高湿度侧，然后水分子被吸收。

转移到较低温度侧以获得分析的效果。

涂层织物价格低廉，并达到一定的透湿性，应用广泛。

但由于其防水透湿性差，手感不理想，市场占有率逐渐下降。

现在开发的湿转移涂层织物使涂层织物再次焕然一新。

不仅具有防水、透湿等高物理性能，而且表布可采用100%特氟龙处理，水洗牢度可达25次。

水蒸气渗透率

水蒸气渗透率水蒸气透过率测试仪采用杯法，用于测试瓶、罐、袋等包装材料和包装容器的水蒸气透过阻隔性能。

是广州国际产品，有三个独立的试验箱，三个独立的称重传感器，可以出三组检测报告。

也称称重式水蒸气透过率测试仪、水蒸气透过率仪等。

工作原理在一定温度下，样品两面形成特定的湿度差，水蒸气透过样品进入干燥面。

通过测量透湿杯随时间的重量变化，计算出样品的水蒸气透过率。

渗透率检测的意义渗透性是薄膜材料的一个重要特性。

准确测量膜和纸的水分子渗透性，对于评价其作为包装材料在不同水蒸气分压环境下的阻水功能具有重要意义。

渗透率检测方法一种很常见的方法是将薄膜（纸张）置于一边是相对湿度很高，另一边是干燥流动气体的环境中。

水分子会透过薄膜（纸张）被干燥气体吹至NIR检测器。

这种方法能够快速给出结果，但是需要有参考方法建立渗透率的标准模型。

另一种则是更为精确的渗透率检测法，甚至能够用来建立前一种NIR快速检测法的标准模型。

该方法是将薄膜（纸张）覆盖在样品盘上，将盘内放置干燥剂、饱和食盐水溶液或水来制造一个与环境不同的水蒸汽分压，从而使水分子透过薄膜（纸张），迁移到达另一边。

这种水分子的迁移可以通过称量样品盘的重量来检测。

这种方法比NIR检测法耗时长，但是结果非常准确，可以得到薄膜（纸张）材料的精确渗透率。

应用适用于测试食品、医药、医疗器械、日用化学等领域的薄膜、片材、纸张、织物、无纺布及相关材料的水蒸气透过性能。

透气3000标准

请注意，如果"透气3000标准"是特定行业或组织内部使用的标准，其具体内容可能与上述标准不同。建议您进一步提供相关背景信000标准"可能指的是一种透气性能测试标准，通常用于评估材料或产品的透气性能。然而，没有具体的背景信息，我无法提供确切的解释。以下是一种常见的透气性能测试标准，供参考：
ASTM E96/E96M-16a：这是美国材料和试验协会（ASTM）发布的标准，用于测量材料的水蒸气透过率。该标准包括两种测试方法：方法A是湿膜法（Wet Cup Method），方法B 是干膜法（Dry Cup Method）。根据测试结果，可以计算出材料的透湿系数（Water Vapor Transmission Rate，WVTR）。

测量穿透率方法ASTM和ISO

测量穿透率方法ASTM和ISO一、ASTM法（又称为重量法、称重法）测试原理：在一定的温度下，使试样的两侧形成一特定的湿度差，水蒸气透过透湿杯中的试样进入干燥的一侧，通过测定透湿杯重量随时间的变化量，从而求出试样的水蒸气透过率等参数。

推荐仪器：WPT-304 水蒸气透过率测试仪基于杯式法测试原理，单次试验测试4个试样，过程全自动化，透湿杯升降称量由电缸稳定控制，数据准确可靠，4个透湿杯均可进行单独试验，试验过程互不干扰，试验结果单独显示。

二、ISO法测试原理：仪器采用红外传感器法测试原理，将待测试样装夹在恒温的干、湿腔之间，试样两侧存在一定的湿度差，由于湿度梯度的存在，水蒸气会从高湿腔向低湿腔扩散，在低湿腔，水蒸气被载气携带至红外传感器，进入传感器时会产生同比例的电信号，通过对传感器电信号的分析计算，从而得到试样的水蒸气透过率和透湿系数。
