3M Friction Shims 产品说明说明书
3M Advanced Materials DivisionIntroductionThe demand for maximum powerdensity, i.e. the transmission of greater force and torque in increasingly compact designs, poses a major challenge to engineers across a variety of industries. 3M Technical Ceramics manufactures friction-enhancing solutions for joining components to withstand highershear forces or transmit higher torque in bolt connections. 3M ™ Friction Shims offer a simple and cost-effective way to reliably transmit up to 4x higher torques or forces thanconventional systems without requiring modifications to the joint design.3M friction shims are metal foils with a coating of electroless nickel embedded with diamond particles. The diamonds indent into the metal mating surface and create a micro-scale interlock. The shims themselves are easy to assemble and can bereused after disassembly. 3M friction shims are thin enough to fit within close engineering tolerances, creating possibilities for lightweight compact design while increasing maximum load and peak torque in bolt connections.3M friction shims have proveneffective in a wide variety of industries, including general mechanicalengineering, machine tools, marine engineering, wind and water power generators, turbines, automotive engineering and motor sports. Our technical specialists have many years of application experience, and conduct in-house laboratory and bench tests to ensure that 3M friction shims meet our customers’ specific requirements.Features• I ncreases the coefficient of static friction• F unction of 3M friction shims is not affected by an oil film • Can be easily retrofitted • Prevents fretting • Highly reproducible • C olor option for distinctive appearance• S him geometries can be tailored to customer specificationApplication• Frictional joints • Flange joints• Joints with central bolt • Bolt connections • Fastener systemsApplication NotesWhen 3M friction shims are used please note:• F or maximum performance, the mating surfaces must have roughness values Rz as given in the technical data sheet.• C ontact pressure of at least 50 MPa is recommended.• W hen designing the joint,ensure that the counterparts to be joined are in full contact.• O nly use in applications with static friction in the contact area.• T he coefficient of static friction depends on a large number ofdifferent parameters.

Values listed are for typical properties and should not be considered minimum or maximum.ProductThe high-voltage corona-resistant tape must be based on ethylene propylene rubber and be capable of operation at the emergency cable temperature of 130°C (266°F). The tape must be capable of being applied in either the stretched or unstretched condition without any resulting loss in either physical or electrical properties.The tape must not split, crack, slip or flag when exposed to various environments (indoor and outdoor). The tape must be compatible with all synthetic cable insulations. The tape must have a dissipation factor of less than 5% at 130°C (266°F) and must have a shelf life of 5 years.Engineering/Architectural SpecificationSplicing and terminating solid dielectric cables shall be done in accordance with drawings engineered by the splice material manufacturer such as the 2047 series available from 3MCompany. All splices and terminations shall be insulated using Scotch™ Brand 23 Electrical Tape.Modulus at 130°C (266°F)A high-voltage splicing tape must constantly maintain a rubber-like consistency throughout the life of a splice. One method of determining a rubber material consistency is by measuring the modulus of the material. The modulus of a material is the stress required to elongate the material to a given elongation.All-Voltage Splicing TapeData Sheet___________________________________________________________________________________________________________________________________________________________________________3M UK PLC3M Ireland 3M UK PLC Electrical ProductsSales OfficeSales OfficeFigure 1 shows the 100% modulus (stress required to elongate 23Tape to 100% elongation) after heat ageing the samples at 130°C (266°F) for a varying number of days. The results indicate a very stable product with excellent “body” or elasticity after oven ageing at 130°C (266°F).Dissipation FactorFigure 2 shows the dissipation of 23 Tape. This test was run according to ASTM-D150 at a stress of 50 V/mil (2.0 MV/m) and a frequency of 60 cycles per second.Dielectric ConstantFigure 3 shows the dielectric constant versus temperature of 23Tape. This test was run according to ASTM-D150 at a stress of 50 V/mil (2.0 MV/m) and a frequency of 60 cycles per second.Dielectric Strength at Elevated TemperaturesA high-voltage splice must not only have a high dielectricstrength at room temperature, but it must also have good values at the temperature at which it is expected to operate. Figure 4shows a plot of dielectric strength versus temperature. This test was run according to ASTM-1000.All-Voltage Splicing TapeData Sheet___________________________________________________________________________________________________________________________________________________________________________3M UK PLC3M Ireland 3M UK PLC Electrical Products Sales OfficeSales OfficeDielectric Strength Versus ThicknessFigure 5 shows a plot of dielectric strength in volts per mil versus thickness. As can be seen by the curve, the dielectric strength in the original thickness of 0.76mm is 800 V/mil (31.5 MV/m).However, the dielectric strength of a 0.51mm thickness of 23Tape is 1200 V/mil(47.2 MV/m). This test was run according to ASTM-1000.Scotch™ Brand 23 Electrical Tape should be applied insuccessive half-lapped, level-wound layers until desired build-up is reached. To eliminate voids in critical areas, highly elongate 23 Tape.Stretch Tape in these critical areas just short of its breaking point.Doing so will not alter its physical or electrical properties. In less critical areas, less elongation may be used.Normally, 23 Tape is stretched to ¾ of its original width in these less critical areas. Always attempt to half-lap to produce auniform build-up. When using 23 Tape for splicing cables from 35kV to 69kV, always elongate the tape throughout the entire splice.Under normal storage conditions, 23 Tape has a 5-year shelf life.The tape is not impaired by freezing nor by overheated storage up to the point of flow which prevents removal from the package.AvailabilityScotch™ Brand 23 Electrical Tape is available in the following roll sizes from your local authorised 3M electrical distributor:19mm x 9M 25mm x 9M 51mm x 9MOther lengths and widths are available by special plete Product and Use Specifications are available through the Electrical Products Division, 3M Company.Important NoticeTechnical information provided by 3M is based on experience and/or tests believed to be reliable, but their accuracy is not guaranteed and the results may not be relevant to every user’s application.

3M Loop Fastener SJ3527N 产品说明书
ASK A 3M EXPERTApril, 20143M™ Loop Fastener SJ3527NProduct Description3M™ Hook and Loop Fasteners o er advanced closure alternatives to zippers, screws, snaps, hooks andmore. They o er greater design exibility, faster product assembly, smoother and cleaner exterior surfacesand improved product performance in many applications. 3M hook and loop fasteners consist of hooks andloops which engage to form a quick fastening attachment. Simply pull the strips apart by hand to disengage.Product FeaturesThe woven nylon hook has exible, self-supporting inverted j-hooks protruding up from the backing withapproximately 300 hooks per square inch (46 hooks/square cm). The woven nylon loop has thousands of soft,pliable napped loops protruding above the backing, providing for thousands of openings and closings (cycles).Both the hook and loop are preshrunk to insure maximum dimensional stability and atness. Standard colorsavailable are black, white and beige, with several custom colors available with extended delivery times andadditional costs.SJ3527N loop is coated on the backside with a high performance rubber based pressure sensitive adhesivewhich allow for easy and convenient attachment to a variety of substrates, including low surface energyplastics.Commonly paired with 3M™ Hook Fastener SJ3526N, this loop fastener can also engage with other 3M™Hook Fasteners.Technical Information NoteThe following technical information and data should be considered representative or typical only and should not be used for speci cation purposes.

System product performance depends upon a number of factors, including the fastener (material, adhesive and area), application method, surface characteristics (material, texture and cleanliness), environmental conditions (moisture, ultraviolet and temperature exposure) and the time it is expected to support a given load. Because many of these factors are uniquely within the user’s knowledge and control, it is required that the user evaluate 3M products to determine whether they are t for a particular purpose and are suitable for the user’s substrates, method of application and desired end use.Rounding the corners, slightly recessing the product into the substrate, or providing raised edges around the Reclosable fastener can reduce the possibility of edge lifting and improve the overall appearance of the fastener on the nished product. Mechanically securing the corners of the fastener with rivets, staples, screws, etc. may also reduce the possibility of edge lifting, but may reduce the closure performance.The two most common techniques for attaching these 3M hook and loop fasteners to various surfaces are summarized below.Pressure Sensitive Adhesive Attachment: The use of pressure sensitive adhesives eliminates or reduces the need for sewing, solvent activation, dielectric or ultrasonic bonding or bulk adhesive bonding. This can result in simplicity, improved safety and lower installation costs. Pressure sensitive adhesive products can be applied manually or automatically using a variety of equipment choices. Contact your 3M Sales Representative to discuss automated equipment options.Surface Preparation: Highly textured surfaces may reduce the ultimate adhesion levels and care should be given to minimize the surface texture or roughness. Adhesive backed fasteners should be applied to surfaces that are clean, dry and free of oil, grease, dust, mold release agents or surface contaminants that could reduce the adhesion. It is recommended to remove any surface contaminants that may reduce adhesion by using a method suited for the type and quantity of surface contaminants present. Isopropyl alcohol is a good general use solvent for cleaning contaminants from surfaces for example.In exceptional cases, especially when removing silicone mold release agents or on rough, porous surfaces, it may be necessary to lightly abrade the surface, use an adhesion promoter, or surface sealer to optimize the adhesive bond to the substrate. The selection of abrasion, priming or sealing methods will depend upon the substrates and the environmental conditions the product will be exposed to during use.Attachment Procedure: To obtain optimum bond to any surface, both the fasteners and the target surfaces should have equilibrated for a minimum of one hour at temperatures between 68°F (20°C) to 100°F (38°C) before application. The liner protecting the adhesive is removed and preferably without touching the adhesive, the fastener is applied to the substrate. Exposure of the adhesive to ambient conditions without the protective liner, before applying to the surface, should be minimized as initial adhesive tack may decrease. Flexible materials should be lying on a hard at surface so as to permit uniform adhesive contact with the surface. Use of a rubber hand roller, press platen or similar device is recommended to ensure full adhesive contact or wet- out with the substrate surface. Approximately 4.5 pounds of force per square inch, (310 grams per square centimeter) is recommended to increase adhesive contact, improving bond strength. For all adhesive applications, it is important to ensure that the edges are rolled down to reduce the chance of edge lifting.Plain backedThe plain backed 3M hook and loop fasteners are most commonly sewn into their applications. Liquid or hot melt adhesives and staples are other forms of attachment that can be utilized.Sewing: Although the selvedge edge was initially developed for stitching on, customers often nd that they get better anchorage when stitching through the 3M hook and loop portions of the fastener – this may be application dependent. The type of thread and stitch type is also best determined based on individual application, however, the fastener should be stitched on all edges for the best seam strength. Typically, special machine adjustmentsare not necessary when using our 3M hook and loop fastenersStorage and Shelf LifeShelf Life when stored in original packaging at 72°F (22°C) and 50% RH is 18 months.Trademarks3M is a trademark of the 3M Company.Family GroupReferencesISO Statement Technical Information SJ3401SJ3522SJ3523SJ3526N SJ3527N SJ3402SJ3531SJ3571SJ3572SJ3532N SJ3533N SJ3530Thickness (mm)Test Condition: Unmatedwithout liner2 2.4 3.2 2.4 3.22 3.2 3.2 2.4 2.03 3.05 2.4Thickness (mm)Test Condition: Matedwithout liner3.10.330.330.330.33 3.10.330.330.33 3.3 3.30.33Material Loop-WovenNylon Hook-WovenNylonLoop-WovenNylonHook-WovenNylonLoop-WovenNylonHook-WovenNylonLoop-WovenNylonLoop-WovenNylonHook-WovenNylonHook-WovenNylonLoop-WovenNylonHook-WovenNylonBacking NoAdhesive Sewon Plasticizerresistant acrylicPSAPlasticizerresistant acrylicPSAHighPerformance rubberbased PSAHighPerformance rubberbased PSANoAdhesiveSewonGeneralPurposerubberbasedPSAHighPerformanceAcrylicPSAHighPerformanceAcrylicPSARubberbased PSARubberbased PSAGeneralPurposerubberbasedPSALiner None Nonprintedpolyolen lm Nonprintedpolyolen lmPolyethylene withredprintingPolyethylene withredprintingNone PolypropylenePolyolen withembossed 3MlogoPolyolen withembossed 3MlogoWhitePolypropyleneWhitePolypropylenePolypropyleneLiner Thickness (mm)0.0890.0890.080.080.080.10.10.080.080.08Liner Color Clear Clear White White White Clear Clear White1.
