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.

KMX-50/3S电磁吸盘用充退磁控制器(智能型)使用说明书西安鸣士机电开发有限公司一、概述平面磨床的充退磁问题一直困扰着磨床生产和使用厂家，以前采用变压整流后通过开关手控进行充退磁，不仅操作繁琐，费力费时，而且充退磁效果很不理想。
加工合金材料及热处理过的材料残磁很大，影响工件的加工精度和工作效率，使磨床的加工范围受到限制，不能满足现代机械制造业的要求。
针对这些问题，我公司精心设计生产了KMX 系列充退磁控制器，有效地解决了平面磨床的充退磁问题，其基本特性和功能如下：采用单片机控制，实现无触点输出，增加了可靠性；充磁输出电流连续可调，可满足不同磨床吸盘加工不同工件对磁力的要求；按退磁曲线自动完成退磁过程，能使每块吸盘达到最佳的退磁效果；退磁时间长短可调，使磨床加工不同的材料均能取得最佳的退磁效果；具有过压、过流、短路、过热等保护功能；具有欠电流保护功能，可通过主机和磁盘联锁实现欠磁保护，以保证设备和人员的安全；故障代码显示，方便排除故障。
体积小，安装调试方便。

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.

充磁消磁器使用方法摘要：一、消磁器原理简介二、消磁器使用方法1.准备工作2.操作步骤3.注意事项三、消磁器的维护与保养四、常见问题及解决办法正文：一、消磁器原理简介消磁器是一种用于消除磁场的设备，其主要原理是在一个开口的铁芯上套上线圈，当线圈接上电源后，会在铁芯中产生磁场。
通过改变线圈的电流方向和大小，可以控制磁场的强度和方向。
二、消磁器使用方法1.准备工作在使用消磁器前，请确保以下准备工作已完成：a.检查消磁器电源线是否完好，电源插头是否松动。
b.确保消磁器与需要消磁的设备（如显示器、机械手表等）的尺寸和形状相匹配。
c.关闭需消磁设备的电源，以免在消磁过程中损坏设备。
2.操作步骤a.将消磁器插上电源并通电。
b.将消磁器平面对着需消磁设备的中心位置，如显示器的屏幕。
c.缓慢地沿着屏幕中心位置画圈，并逐渐将圆圈扩大，直至超出屏幕范围。
d.缓慢地将消磁器从屏幕附近移开，直至移到远离设备的地方，过程中切勿断电。
e.移开消磁器后，关闭消磁器电源。
3.注意事项a.操作过程中，确保消磁器的线圈与设备表面保持平行。
b.画圈和移开的动作一定要缓慢，避免剧烈动作。
c.避免在消磁过程中让消磁器与设备发生碰撞，以免损坏设备。
d.消磁器电源电压应与供电电路相匹配，以免损坏电路。
三、消磁器的维护与保养1.定期检查消磁器线圈和铁芯是否有损坏，如有损坏应及时更换。
2.保持消磁器清洁，避免灰尘和污垢影响使用效果。
3.避免在高温、潮湿、易爆的环境中使用消磁器，以免发生危险。
四、常见问题及解决办法1.问：消磁器无法正常工作怎么办？答：检查电源线是否完好，电源插头是否松动，重新插上电源尝试。
2.问：消磁过程中设备受损怎么办？答：立即停止使用消磁器，检查设备损坏原因，如有需要，请联系售后服务。
3.问：消磁效果不明显怎么办？答：检查消磁器与设备是否匹配，尝试增加消磁时间或更换消磁器。
4.问：消磁器损坏怎么办？。
