桥梁缆索防腐与维护-Tedlar-聚氟乙烯胶带
桥梁缆索防腐与维护－Tedlar®聚氟乙烯胶带[摘要] 结合桥梁缆索防腐蚀保护系统，介绍了一种具有优良耐候性能的Tedlar®聚氟乙烯缆索保护胶带，同时列举了部分国内外的实际使用案例。
[关键词] 斜拉桥；悬索桥；缆索；防护；腐蚀1．概述桥梁的缆索系统是现代大跨度桥梁，如斜拉桥、悬索桥和拱吊桥的主要承重结构，缆索系统长期承受动载和静载，暴露在风雨、潮湿和污染的空气环境中，既受“应力腐蚀”、“疲劳腐蚀”，又受“金属腐蚀”作用，很容易遭受腐蚀破坏，一旦发生腐蚀，后果不堪设想。
国内外已有桥梁缆索破坏失效的实例，引起的安全事故和经济损失非常严重。
1987年，Stafford 和Watson对世界范围的近100座斜拉索桥进行现场调查表明，几乎在过去几十年间全球所建的斜拉桥大都因为缆索腐蚀问题而产生极大风险[1]。
桥梁缆索防腐一直是人们关注的问题，缆索索体防护主要应用的是类似于电线电缆的防护方法，如热挤HDPE护套防护的平行钢丝索、HDPE套管防护的平行钢绞线索。
平行钢绞线索常用的防护方法如图1所示：在镀锌钢绞线外热挤HDPE护套，再采用防腐油脂或石蜡密封钢绞线，以排除管内空隙中的空气和水分，最外层用黑色的HDPE套管，以形成多层防护的钢缆。
虽然HDPE是致密的材料，有较好的阻隔水汽作用，但是直接暴露在自然环境中，不仅要经受紫外老化、高温、严寒的考验，还需要抵御各种有害尾气和潮湿空气的侵蚀，HDPE套管上应力集中点容易出现裂纹，极易造成钢索的腐蚀。
HDPE护套材料中加入少量碳黑可以增强其耐老化性能，但护套也因此颜色为黑色，在阳光照射下其表面温度可高达65o C,而白色护套在相同条件下温度仅仅为40o C[2]。
护套与内部钢索由于收缩率不一致，护套表面温度剧烈变化，会削弱HDPE护套的长期使用性能。
为了满足缆索HDPE套管的耐久性需求，在管外缠绕耐候性和耐腐蚀性能极佳的Tedlar®保护胶带（一般重叠50％），不仅能够延长HDPE套管的使用寿命，而且白色或浅色的胶带能降低护套表面温度波动程度。

Bulletin No. 5600PD9601July 1996Oxford, OH, USAProduct Data BulletinMYLAR ® BUS BAR INSULATION—A THIRTY YEAR TRACK RECORDFor more than 30 years, Square D has used Mylar ® to insulate bus bars in I-Line ®and I-Line II Busway. The purpose of this paper is to provide information demonstrating that Mylar is both a proven and reliable insulation system.QUESTIONS AND ANSWERSWhat is Mylar ®?Mylar is a polyester film made from polyethylene terephthalate, the polymer formed by the condensation reaction of ethylene glycol and terephthalic acid.Mylar has an average dielectric strength of 7,000 volts for 1 mil film, a tensile strength of 23,000 psi, and an excellent resistance to most chemicals andmoisture. Mylar also remains flexible throughout temperature extremes from –60° to 150°C and does not become brittle with age.Does Mylar ® meet To meet to Underwriters Laboratory (UL) requirements, UL Listed busways UL requirements?cannot exceed a total operating temperature of 95°C in an ambient temperature of 40°C at full load. This requirement applies to the complete busway system, not just a single busway component. At loads up to and including the full load rating and at 40°C ambient temperature, I-Line and I-Line II Busway will not exceed a total operating temperature of 95°C. Actual supplier testing (DuPont #EL-63-2)has proven Mylar to have a conservative Class B, 130°C thermal rating, which is 35°C above the approved operating temperature of UL Listed busways.What about reliability?I-Line and I-Line II bus bars are insulated with two layers of 7.5 mil Mylar. Once assembled, every busway length and fitting must pass a 7,000Vdc (4,950Vac)hi-potential test before shipment from the factory. The factory test is conducted at eight times greater than the maximum operating voltage to ensure the highest quality insulation with every section of busway delivered.Mylar has many electrical applications in addition to insulating bus bars. Many manufacturers also use Mylar as insulation in transformers and electric motors.In fact, one of the largest electric motor manufacturers in the United States has used Mylar as a stand-alone insulator in Class B motors for over 35 years.Laminates containing Mylar are commonly used in Class F motors with ratings of 115°C and higher.ELECTRICAL PROPERTIES With an excellent balance of chemical, thermal, and physical properties, the OF MYLAR ®electrical properties of Mylar offer unique design capabilities to the electrical industry.Film ThicknessThe average dielectric strength for 1 mil film is 7,000 volts. For 7.5 mil film, the dielectric strength is approximately 2,700 volts/mil for an excellent dielectric strength of 20,250 volts. I-Line and I-Line II Busway use two layers of 7.5 mil film for a total insulation thickness of 15 mil. As with most materials, the ac dielectric strength of Mylar film in volts/mil decreases as film thickness increases. This is illustrated in Figure 1, page 2. After being tested at a 500volts/second rate of rise, corona occurs within seconds and the film begins to melt before the actual breakdown occurs.Bulletin No. 5600PD9601July 1996Mylar ® Bus Bar Insulation—A Thirty Year Track Record2Figure 2: Dielectric strength vs. temperatureFigure 1: Dielectric strength vs. thicknessInsulation ResistanceAnother outstanding property of Mylar is its high insulation resistance over a wide temperature range. As shown in Figure 2, the dielectric strength remains constant over a temperature range from 25°C up to 150°C.Bulletin No. 5600PD9601 Mylar® Bus Bar Insulation—A Thirty Year Track RecordJuly 1996Bulletin No. 5600PD9601July 1996Mylar ® Bus Bar Insulation—A Thirty Year Track RecordPHYSICAL AND THERMAL Mylar polyester film retains good physical properties over a wide temperature PROPERTIES OF MYLAR ®range from –60° to 150°C. Its shear strength is significantly higher than published data for other polymeric insulating materials. Mylar is also resistant to electrical creepage.Shear StrengthShear strength was measured by a punch-type test according to ASTM D-732.This measurement is reported in pounds of force required to shear divided by the product of the circumference and the thickness. These tests showed that 5and 10 mil Mylar films have shear strengths of 15.0 (21.5) and 13.6 (19.5) kg/mm 2(kpsi), respectively.Heat Aging and Service LifeThe film manufacturer’s maximum service temperature usually recommended for Mylar polyester film is 150°C. UL Listed busways are designed not to exceed a total operating temperature of 95°C. Where extensive exposure, severeenvironmental conditions, or unusual physical requirements such as severe flexing are involved, reducing the service life of Mylar may be necessary.Because the Mylar in I-Line and I-Line II Busway is totally enclosed within the housing, the Mylar is protected against extensive exposure, severeenvironmental conditions, and flexing. As a result of this protection and when subjected to normal operating conditions, long life can be expected.CHEMICAL PROPERTIES Mylar polyester film exhibits good resistance to the action of many chemical OF MYLAR ®reagents, solvents, varnishes, and other contaminants and is virtuallyimpermeable to the liquid phase of most chemicals and reagents. Oils and greases such as penetrating oil, lard, cottonseed oil, and motor oil will notpenetrate through 1mil film even after two months of constant exposure at room temperature. Mylar is relatively insensitive to moisture absorption, absorbing less than 0.8% moisture when totally immersed in water over a 24-hour period (ASTM D-570-63).SUMMARYMany types of bus bar insulation systems can exceed the maximum allowable operating temperature as required by UL. It is important to understand that UL Listed busways are designed not to exceed a total operating temperature of 95°C, which falls into Class A limits . Thus, high quality busway designs, like I-Line and I-Line II Busway, will never reach operating temperatures of 130°C under normal operating conditions. Unlike our competitors, Square D usesfull-size bus bars in I-Line and I-Line II Busway. Full-size bus bars contribute to cooler operation of the busway system, lower voltage drop, and higher electrical efficiency. This equates to a lower operating cost and long life .Today, I-Line and I-Line II Busway installations are in operation throughout the world, dating back to the early 1960s. Test data for new insulation systems is generated in laboratory conditions. Historical data generated from actualapplications is the most relevant and valuable data available. With more than 30years of both laboratory and historical data along with proven performance,Square D Busway with Mylar insulation has proven reliability in the industry.Source: DuPont Films EnterpriseI-LINE, SQUARE D, and are Registered Trademarks of Square D Company.Mylar is a Registered Trademark of E.

投资光伏电站 先了解材料
投资光伏电站请先了解材料清单光伏电池组件来源:世纪新能源网作者:肖蓓2014/8/25 9:20:56我要投稿关键词: 光伏电站投资光伏背板杜邦北极星太阳能光伏网讯:频发的质量问题、高衰减率组件正在中国西部光伏电站蔓延，可能会将过去三年积累的光伏电站成绩打入尘埃。
“部分多晶硅电池组件2-3年功率衰减3.8%－7.0%，非晶硅3年功率衰减达20%。
”中科院电工所在对青海省太阳能光伏电站后评估检测后得出令人惊讶的结果。
根据鉴衡认证中心调查，425座太阳能电站中，30%建成的3年以上电站都不同程度出现了问题；由于组件的质量问题，有些建成三年的电站设备衰减率甚至高达68%。
如果组件一年衰减超过5%，照此速度，五年后这个电站就报废了。
随着“婴儿期”（运行一年）失效率组件的出现，建设1年的电站成本、收益都出现了较大波动。
这样的电站如何保证投资回报率？如何获得银行贷款？如何让投资者、业主放心？以国内现有的招标交易及竞争环境，单独的太阳能电站组件供应商没有力量挽回这一局面，有些事情，需要电站业主、投资商自己把关。
未经实绩验证的材料损害组件根本组件是太阳能电站最重要的组成设备，电站的质量、发电量、收益率、价值都与它息息相关。
它主要由太阳电池、封装材料、背板、玻璃、边框、接线盒等组成，这些材料都对组件性能、质量产生影响，电池片是核心，外面的封装材料都是为了保护它，其中一个关键的保护材料是处于最外层的背板，一旦背板失效，里面的封装材料、电池片就如失去蔽护的花朵，随环境凋零。
背板是光伏组件背面的一层复合结构材料，将电池片和组件封装材料与大气环境隔离，为组件提供绝缘保护，它需要长期耐受各种环境应力作用，对组件在户外的可靠性、功率衰减和使用寿命都至关重要。
随着国内电站装机的不断攀升，市场上出现了采?不同材料和结构类型的背板，目前比较常见的背板外层保护材料有杜邦™特能®(Tedlar®)PVF薄膜、PVDF薄膜、FEVE涂料、PET聚酯/耐水解PET、PA聚酰胺。

杜普汤姆 Tedlar 胶囊胶水选择指南说明书
Technical BulletinGeneralThis guide is intended to assist the manufacturer in the selection of adhesives for laminating DuPont ™ Tedlar ® polyvinyl fluoride (PVF) film to a variety of substrates. Lamination and quality control guidelines are also included for laminating Tedlar ® PVF film to:• Aluminum• Galvanized steel • Vinyl fabric• Thermoplastic sheet • Vinyl wall coveringThis information is believed to be the best currently available and is offered to help with your own experimentation and evaluations. This information will be revised as additional information becomes available.Adhesive StorageTedlar ® adhesives are best used within two years from date ofmanufacture. Best used dates are guidelines to insure the material maintains its viscosity and appearance. In the event material has exceeded two years from date of manufacture, it may be assessed for use in the following manner:1. Insure the material is at room temperature2. Insure the material is mixed (10 – 15 minutes gentle agitation on drum roller is suitable)3. Collect a small sample of adhesive in a clear vessel to inspect visually for presence of non-soluble gel particles (do not use adhesive if non-soluble gel particles are visible)4. Adhesive may be adjusted to the desired viscosity by thinningwith tolueneProtect the adhesives from temperature and humidity extremes. If adhesives are exposed to temperatures below 4°C (40°F), they must be brought to room temperature, 22°C (70°F), andthoroughly mixed as separate units. Additional mixing is required when blending the compounds.DuPont ™ Tedlar ® Polyvinyl Fluoride FilmsAdhesive and Lamination GuideFlexible Product AdhesivesOver the last 25 years DuPont has developed a family ofadhesives used for laminating Tedlar ® PVF film to a wide range of substrates. These adhesives are characterized by excellent resistance to moisture and UV radiation.DuPont flexible product adhesives are versatile acrylic adhesives developed specifically for laminating Tedlar ® PVF film to a variety of substrates. With these adhesives, high-quality, long-lasting bonds can be achieved to meet demanding quality control specifications of manufacturers.A blend of acrylic adhesive 68070 and Epon ™ 828 is used to bond Tedlar ® PVF film to aluminum and galvanized steel in various gauges.Acrylic adhesive 68080 is a liquid that can be pre-applied to Tedlar ® PVF film to facilitate lamination of products for interiors, such as vinyl wall coverings, and for exteriors, such as architectural siding, awnings, flexible sign faces, and fabric structures.Adhesive CharacteristicsDuPont flexible product adhesives have varying degrees of activation temperature, amine reactivity, and hardness.Key characteristics of these adhesives are shown below:Increasing hardness Increasing amine reactivity Increasing activation temperatureLamination temperature149 – 210°C 300 – 410°F135 – 210°C275 – 410°FToluene, %5570Isopropanol, %4530Solvent CompositionProduct AdvantagesThese flexible product adhesives have superior durability that resists light, moisture degradation and discoloration. These adhesives are used in a wide variety of substrates and broad range of conditions over many years of service.Product LimitationsTedlar® adhesives are best used within two years from date of manufacture. See guidance on Adhesive Storage.68070 has been observed to interact with some components in a flame-retardant vinyl causing yellowing.68070/Epon™ 828 mixtures only have an 8-hour pot life. 68080 is incompatible with 68070.Ketone solvents should be avoided in diluting the adhesives as yellow discoloration will result.Caution: DuPont does not warrant the “lamination.” The performance of the “system” is the sole responsibility of the applicator. DuPont will provide consultation and our best information in assisting the customer to achieve satisfactory lamination.Safety PrecautionsThese products are FLAMMABLE AND CONTAIN HARMFUL VAPORS. Store containers away from heat, sparks, and open flames. Keep containers closed when not in use. Before usingthese products, read the Safety Data Sheet.Polycarbonate68080 or 68070ABS68080 or 68070PVC Film68070/Epoxy, 68080Vinyl Siding68080Vinyl Wall Covering68080Laminate Adhesive Selection GuideFlexible Adhesive ApplicationHeat the adhesive to room temperature and mix accordingto instructions. Dilute with toluene to desired viscosity. Apply adhesive using spray gun, brush, dipping, extrusion, rollers, doctor blade/wire wound rod, reverse roller coater, roller coater or gravure coating. Lamination can proceed as soon as the adhesive is dry. Toluene and/or methyl ethyl ketone (for cleanup only) may be used to clean up equipment.Note: Trial laminations should be made to test adhesive suitability. Adhesives, especially non-DuPont, must be tested for the specific application. Some epoxies may not bond well to the Tedlar® PVF film. The harder polyester adhesives do not bond well to Tedlar® PVF film. Isocyanate curing agents generally enhance adhesion. Some phenolic materials or curing agents may cause staining of the Tedlar® PVF film.Lamination GuidelinesAdhesives, thinned to a desired viscosity with toluene, can be applied to the film using a variety of coating methods. The coated film is normally passed through an oven where the solvent is evaporated to obtain a non-blocking adhesive coating. Thorough drying is essential as residual solvent may cause blocking in the roll. Drying temperatures of 77–104°C (170–220°F) coordinated with proper film web speed and tension are presently being used with success. Excessive machine direction (MD) film stretching and transverse direction (TD) film shrinkage can result from improperly controlled oven temperature and film web tension. Laminating DuPont™ Tedlar® PVF Film to Aluminum Lamination is accomplished by cleaning the metal, depositinga controlled conversion coating on the metal, coating the metal with a solvent-based adhesive, evaporating the solvent, heating the metal to 195–205°C (383–401°F) to activate the adhesive, combining with Tedlar® PVF film in nip rolls and quenchingthe laminate.MaterialsFilm – Tedlar® PVF film type TWH15BL3 and colorsAdhesive – DuPont™ 68070, Epon™ 828Metal – AluminumAdhesive Mixing and ApplicationThe adhesive is prepared by the following formula by weight: While stirring the 68070, slowly add Epon™ 828. Blend the mixture for approximately 5 minutes with a suitable mechanical mixer. Adjust adhesive coater to lay down 37–50 µm (1.5 to2.0 mil) wet adhesive equivalent to 6–7.5 µm (0.23 to 0.30 mil)of dry adhesive. Adjust viscosity by diluting with toluene.During normal operation, the rate of solvent evaporation is slight enough to have no effect on the percent solids. If prolonged halts in coating occur, the viscosity must be checked and adjusted with toluene to the original value. Pot life of the mixed adhesive is8 hours.The solvent is removed and adhesive activated in an oven of such length that the metal is in the oven from 30 to 90 seconds. The metal temperature must be 195–205°C (383–401°F) at the end of the oven followed by immediate lamination.LaminationThe laminating equipment consists of a pair of combining or “nip” rolls that are unaffected by the operating temperature of 175°C (347°F). A nip pressure of 87–175 N/cm (50–100 lb/in) of width must be used. A film wrap of at least 90° on the uppernip roll must be used to prevent wrinkling.Adhesive 6807029Epon™ 8281Laminating DuPont™ Tedlar® PVF Film to Galvanized Steel Lamination is accomplished by cleaning the metal, depositinga controlled conversion coating on the metal, coating the metal with a solvent-based adhesive, evaporating the solvent, heating the metal to activate the adhesive, combining with Tedlar® PVF film in nip rolls and quenching the laminate.MaterialsFilm – Tedlar® PVF film type TWH15BL3 and colorsAdhesive – DuPont™ 68070, Epon™ 828Metal – Hot dipped galvanized steel, generally G-90, is used.The steel must have good forming quality and preferably minimum spangle, temper rolled, lock forming quality or extra smooth spangle. The metal must be free of white rust to enable proper surface treatment and adhesion. Prior to lamination the metal being used must have all mill oils removed.The optimum thickness metal to be laminated is 18 gauge(0.0516”).Laminates on metal, 22 gauge (0.0366”) or lighter, may be made on any standard type of galvanized, including commercial quality, regular spangle. Better forming quality is preferred.Metals heavier than 22 (0.0366”) gauge must be minimum spangle or spangle-free surface. Commercial quality, regular spangle steel is not acceptable in gauges heavier than 22 gauge (0.0366”). Care should be taken when laminating metal heavier than 22 gauge (0.0366”) and formed to a radius of less than3 mm (1/8”) to prevent splitting.Adhesive Mixing and ApplicationThe adhesive is prepared by the following formula by weight Adhesive 6807029Adhesive Epon™ 8281While stirring the 68070, slowly add Epon™ 828. Blend the mixture for approximately 5 minutes with a suitable mechanical mixer. Adjust the coater to lay down 37–50 µm (1.5–2.0 mil) wet adhesive equivalent to 6–7.5 µm (0.23–0.30 mil) of dry adhesive.During normal operation, the rate of solvent evaporation is slight enough to have no effect on the percent solids. If prolonged halts in coating occur, the viscosity must be checked and adjusted with toluene to the original value. The pot life of the mixed adhesive is 8 hours.The solvent is removed and adhesive melted in an oven of such length that the metal is in the oven from 30 to 90 seconds. The metal temperature must be 195–205°C (383–401°F) at the end of the oven followed by immediate minationThe lamination equipment consists of a pair of combining or “nip” rolls that are unaffected by the operating temperature of 175°C (347°F). A nip pressure of 10–20 kg/cm (50–100 lb/in) of width must be used. A film wrap of at least 90° on the upper nip roll must be used to prevent wrinkling.Laminating DuPont™ Tedlar® PVF Film to PVC for Outdoor ApplicationsSince there are many formulations of PVC, optimum laminating conditions may vary with the PVC formulation. The following is given as a suggested starting point for lamination studies and has given good results with a number of PVC films.MaterialsFor opaque laminates, pigmented Tedlar® PVF film, such as TWH15BL3 white film, can be used. Under the pigmented films, a higher proportion of epoxy can be used, and a 68070/ Epon™ 828 ratio of 18/1 by volume (14/1 by weight) can be used. Adhesive ApplicationApply 7.5–12.7 µm (0.3 to 0.5 mil) (measured on dry resin) of adhesive to the DuPont™ Tedlar® PVF film or PVC. Dry the adhesive at 66–71°C (150–160°F), film temperature. After drying, the adhesive will appear practically dry to touch and only slightly tacky. If the PVC is coated, note that the adhesive solvent contains toluene, which attacks vinyl, but under the above conditions it will probably be flashed off so fast that this will not cause trouble. Note also that ketones should not be used for dilution as they can cause yellowing of the 68070 adhesive. LaminationCombine the Tedlar® PVF film and PVC in a nip roll, with a glue line temperature of at least 79°C (175°F) but preferably not over 121°C (250°F). Some people have accomplished such laminations with roll temperatures of about 121°C (250°F).Laminating DuPont™ Tedlar® PVF Film to Thermoplastic SheetMaterialsFilm – Any Tedlar® PVF filmAdhesive – DuPont™ 68070 or 68080Plastic – Polystyrene, Polymethacrylate, Polycarbonate,Acrylonitrilebutadiene-styrene (ABS)6807034460(0.2–0.3 dry mil) 68080303706–7.5 dry µm(0.2–0.3 dry mil) Adhesive ApplicationApply the adhesive, thinned with toluene to a desired viscosity, to the film using adhesive coating equipment.

Drying temperatures of 77–104°C (170–220°F) coordinated with proper film web speed and tension arepresently being used with success. Excessive MD film stretching and TD film shrinkage can result from improperly controlled oven temperature and film web tension.LaminationLaminating adhesive-coated Tedlar ® PVF film to thermoplastic sheet is easily accomplished at the extruder. The operation consists of combining the film with the hot sheet at the first nip of the take-off stack. Stack temperatures of 149°C (300°F) or higher are necessary to heat activate the adhesive and adequately bond the film. The unwind roll of Tedlar ® PVF film should be positioned so that the film wraps the top roll 30° or more and tension across the sheet is uniform. Press Operations: 1-1/2 minutes, minimum lamination temperatures: 135–149°C (275–300°F), 100–150 psi; cool to 38°C (100°F) before removing from press.Laminating DuPont ™ Tedlar ® PVF Film to Vinyl Wall CoveringWall covering having excellent stain resistance and cleanability is possible with Tedlar ® SP PVF film. Lamination is accomplished by combining adhesive coated Tedlar ® SP PVF film with preheated vinyl in heated nip rolls. The finished product is recommended for interior applications only.Film TypesTedlar ® type TTR5JAM8 and TTR10AM8 coated with 6–7.5 µm (0.2–0.3 mil) dry 68080 acrylic adhesive from DuPont. CTRWCAM919 is available and is already adhesive minationLaminating adhesive-coated Tedlar ® PVF film to vinyl has been successfully demonstrated on various types of equipmentfamiliar to the wall covering industry. The operation consists of combining the film with the vinyl in hot nip rolls, heating the composite to 149–177°C (300–350°F) and embossing. The unwind roll of Tedlar ® PVF film should be positioned so that the film wraps the top nip roll at least 90° and tension across the sheet is uniform.。
