Low-end response of the transducer is a function of its associated electronics.2. Removing cable exposes accelerometer interior to environment. See Piezoelectric Instruction Manual before replacing cable assembly.3. When exposed to high g and large displacement, the cable must be tied down as close to the accelerometer as possible to prevent cable whip and subsequent cable failure.4. Short duration shock pulses, such as those generated by metal-to-metal impacts, may excite transducer resonance and cause linearity errors. See TP290 for more details.5. Adhesives such as petro-wax, hot-melt glue, and cyanoacrylate epoxy (super glue) may be used to mount the accelerometer temporarily to the test structure. To remove an epoxy-mounted accelerometer, first soften the epoxy with an appropriate solvent and then twist the unit off with the supplied removal wrench. Damage to sensors caused by inappropriate removal procedures are not covered by Endevco’s warranty.6. Maintain high levels of precision and accuracy using Endevco’s factory calibrationservices.

Prior to paint application all surfaces should be assessed and treated in accordance with ISO 8504:2000. Oil or grease should be removed in accordance with SSPC-SP1 solvent cleaning.Abrasive Blast CleaningAbrasive blast clean to Sa2½ (ISO 8501-1:2007) or SSPC-SP6 (or SSPC-SP10 for optimum performance). If oxidation has occurred between blasting and application of Interzinc 22, the surface should be reblasted to the specified visual standard.Surface defects revealed by the blast cleaning process should be ground, filled, or treated in the appropriate manner.A surface profile of 40-75 microns (1.5-3.0 mils) is recommended.Shop Primed SteelworkInterzinc 22 is suitable for application to unweathered steelwork freshly coated with zinc silicate shop primers.If the zinc shop primer shows extensive or widely scattered breakdown, or excessive zinc corrosion products, overall sweep blasting will be necessary. Other types of shop primer are not suitable for overcoating and will require complete removal by abrasive blast cleaning.Weld seams and damaged areas should be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6.Damaged / Repair AreasAll damaged areas should ideally be blast cleaned to Sa2½ (ISO 8501-1:2007) or SSPC-SP6. However, it is acceptable that small areas can be power tool cleaned to Pt3 (JSRA SPSS:1984) or SSPC-SP11, provided the area is not polished. Repair of the damaged area can then be carried out using a recommended zinc epoxy primer - consult International Protective Coatings for specific advice.SURFACEPREPARATIONInterzinc 22 is supplied in two parts, a liquid Binder base component QHA285 (Part A) and a Powder component (Part B). The Powder (Part B) should be slowly added to the liquid Binder (Part A) whilst stirring with a mechanical agitator. DO NOT ADD LIQUID TO POWDER. Material should be filtered prior to application and should be constantly agitated in the pot during spraying. Once the unit has been mixed it should be used within the working pot life specified.3.1 part(s) : 1 part(s) by volumeMix ratio is given for advice; always mix the product in the proportions supplied .Suitable - small areas only Typically 25-50 microns (1.0-2.0 mils) can be achieved Not recommended International GTA803,International GTA415 or International GTA138International GTA803, International GTA138 or International GTA415Do not allow material to remain in hoses, guns or spray equipment. Thoroughly flush all equipment with International GTA803/International GTA415 /InternationalGTA138. Once units of paint have been mixed they should not be resealed and it is advised that after prolonged stoppages work recommences with freshly mixed units.Clean all equipment immediately after use with International GTA803/International GTA415/International GTA138. It is good working practice to periodically flush out spray equipment during the course of the working day. Frequency of cleaning will depend upon amount sprayed, temperature and elapsed time, including any delays.All surplus materials and empty containers should be disposed of in accordance with appropriate regional regulations/legislation.As regionally available. Do not thin more than allowed by local environmental legislation As regionally available.RecommendedRecommendedTypical pump Graco X-Treme 40:1 or similar Gun DeVilbiss MBC-510 or JGA-510 (Binks 2100)Air Cap 704 or 765 (Binks 66SD or 68PB)Fluid TipE (1.8mm) or D (2.2mm) or Binks 66,67Tip Range 0.38-0.53 mm (15-21 thou)Total output fluid pressure at spray tip not less than 112 kg/cm² (1593 p.s.i.)APPLICATIONMixingMix RatioWorking Pot LifeAirless Spray Air Spray(Pressure Pot)Brush Roller ThinnerCleanerWork StoppagesClean Up5°C (41°F) 15°C (59°F) 25°C (77°F) 40°C (104°F) 12 hours8 hours4 hours2 hoursPage 2 of 4Prior to overcoating, Interzinc 22 must be clean, dry and free from both soluble salts and excessive zinc corrosion products.Surface temperature must always be a minimum of 3°C (5°F) above dew point.When applying Interzinc 22 in confined spaces ensure adequate ventilation.The minimum overcoating interval is dependent upon the relative humidity during cure.If thinning is required to assist spray application in warmer climates, (typically >28°C (82°F)), it is recommended that International GTA803 thinners are usedIt is recommended that prior to overcoating a solvent rub test to ASTM D4752 should be undertaken. A value of 4 indicates a satisfactory degree of cure for overcoating purposes.At relative humidities below 55%, curing will be retarded. Humidity may be increased by the use of steam or water spraying. However, cure at relative humidities below 55% is more effectively achieved byincorporating the Low Humidity Cure Accelerator*; some example overcoating times at 15ºC (59ºF) are detailed below;Relative Humidity (%)203040Minimum Overcoating Interval24 hours 10 hours 10 hoursThe Interzinc 22 Application Guidelines contain further information on expected cure times at lower relative humidities.Excessive film thickness and/or over-application of Interzinc 22 can lead to mudcracking, which willrequire complete removal of the affected areas by abrasive blasting and re-application in accordance with the original specification.Care should be exercised to avoid application of dry film thickness in excess of 125 microns (5 mils).For high temperature systems the thickness of Interzinc 22 should be restricted to 50 microns (2 mils) d.f.t. Continuous dry temperature resistance of Interzinc 22 is 400°C (752°F) if left untopcoated, however, if this product is used as a primer for Intertherm 50, the dry temperature resistance will be 540°C (1004°F).Untopcoated Interzinc 22 is not suitable for exposure in acid or alkaline conditions or continuous water immersion.This product has the following specification approvals:• AISC Specification 348-04 Research Council for Structural Connections Class B Coating • UNE 48293 (Spain)Note: VOC values are typical and are provided for guidance purpose only. These may be subject to variation depending on factors such as differences in colour and normal manufacturing tolerances.Low molecular weight reactive additives, which will form part of the film during normal ambient cure conditions, will also affect VOC values determined using EPA Method 24.*Only available in Europe, China, Middle East, Africa and Russia.PRODUCTCHARACTERISTICSWhen it is necessary for Interzinc 22 to be overcoated by itself due to low dry film thickness, the coating surface must be fresh and unweathered. A minimum of 50 microns (2 mils) d.f.t of any subsequent coat of Interzinc 22 is needed to ensure good film formation.Before overcoating with recommended topcoats ensure the Interzinc 22 is fully cured (see above) and if weathering has occurred all zinc salts should be removed from the surface by fresh water washing, and if necessary scrubbing with bristle brushes.Typical topcoats and intermediates are:Intercure 200 Intergard 475HS Intercure 420 Intertherm 50Intergard 251 Interseal 670HS Intergard 269 Intertherm 715Intergard 345In some cases it may be necessary to apply a mist coat of suitable viscosity to minimise bubbling. This will depend upon the age of the Interzinc 22, surface roughness and ambient conditions during curing and application. Alternatively, an epoxy sealer coat, such as Intergard 269, can be used to reduce bubbling problems.For other suitable topcoats/intermediates, consult International Protective Coatings.SYSTEMSCOMPATIBILITYPage 3 of 4Further information regarding industry standards, terms and abbreviations used in this data sheet can be found in the following documents available at :• Definitions & Abbreviations• Surface Preparation• Paint Application• Theoretical & Practical Coverage• Interzinc 22 Application GuidelinesIndividual copies of these information sections are available upon request.ADDITIONAL INFORMATION This product is intended for use only by professional applicators in industrial situations in accordance with the advice given on this sheet, the Material Safety Data Sheet and thecontainer(s), and should not be used without reference to the Material Safety Data Sheet (MSDS) which International Protective Coatings has provided to its customers.All work involving the application and use of this product should be performed in compliance with all relevant national, Health, Safety & Environmental standards and regulations.In the event welding or flame cutting is performed on metal coated with this product, dust and fumes will be emitted which will require the use of appropriate personal protective equipment and adequate local exhaust ventilation.If in doubt regarding the suitability of use of this product, consult International Protective Coatings for further advice.SAFETYPRECAUTIONSPACK SIZEUnit SizePart APart B VolPack Vol Pack For availability of other pack sizes, contact International Protective Coatings.13.78 litre 10.42 litre15 litre3.36 litre20 litre5 US gal3.78 US gal 5 US gal1.22 US gal 5 US galSHIPPING WEIGHT(TYPICAL)Unit Size Part A Part B 13.78 litre 11.6 kg 25.8 kg 5 US gal34.4 lb72.4 lbShelf LifePart A 6 months minimum at 25°C (77°F).Part B 12 months minimum at 25°C (77°F).Subject to re-inspection thereafter.

(完整word版)MCM-22文献非常实用哦
文献综述0．前言1990年，MOBIL公司首次报道了MCM-22分子筛的合成，由于MCM—22分子筛含有12元环和10元环两种孔道体系，以及它作为催化剂的载体具有良好的水热稳定性，较大的孔结构，比表面积和微孔容积,已引起了国内外研究者的极大关注。
MCM—22分子筛在催化裂化，异构化，甲烷无氧芳构化,苯与短链烯烃烷基化有着广泛的应用前景。
1．MCM—22分子筛的结构特性MCM—22分子筛拥有两套互不相通的多维孔道体系（如图1）。
一套为二维正弦孔道，有效孔径为（0。
4nm×0。
59nm），另一套是由含有十二元环的超笼（0。
71nm×0。
71nm×1。
82nm)组成,其开口也为十元环。
MCM—22分子筛较同样是十二元环的β沸石（线性通道孔径约0.57nm×0。
75nm，非线性曲折通道孔径约0。
56nm×0.65nm）略小。
因而MCM-22分子筛对于某些反应具有更好的选择性，如在苯与乙烯、丙烯烷基化反应生产苯乙烯、异丙苯时，其中副产物二乙苯、二异丙苯由于在MCM—22分子筛的十元环孔道中受阻，而有较高的选择性。
MCM-22分子筛较十元环的ZSM—5有更大的孔容，当有较多支链的烃异构体参加反应时,其进入ZSM-5十元环孔道是受阻的，然而MCM-22分子筛的十二元环孔道对多支链化合物是畅通的，会有较多的I—C5生成，此外,对不同分子的扩散性质的差别也体现了它的择形性。
2．MCM—22分子筛的一般物化性能通过对MCM-22分子筛的结构物性测定表明，N2吸附等温线的形状表现为LangmuirⅡ型，用ASAP-200静态容量法低温吸氮装置,测定MCM-22、Beta、ZSM-5分子筛的孔结构数据如表1所示。
