Teknor Apex www.teknorapex.com of Sarlink 9156B, a workhorse compound for pipe seals, but as a lubricated compound it exhibits a coefficient of friction that is only 16% as high. “The substantially greater lubricity of new Sarlink 9156-02 is a big advantage for inserting the seals into the fittings – a me- chanical process in which lubrication increases speed and helps to prevent rejects,” said Stef Hordijk, general sales manager for the Thermoplastic Elastomer Division of Teknor Apex. “Fittings with lubricated seals also facilitate pipe insertion, which is done by hand at the construction site. By reducing the forces needed for inserting the pipe into the fitting, lubrication helps prevent improper assembly and damage to the seal.” Like Sarlink 9156B, the new lubricated compound exhibits greater retention of sealing force over a period of years than rubber, prolonging the working lives of pipe seals, which must prevent leakage from within the pipe and seepage from out- side. Sealing force is measured by the degree of stress relaxa- tion. Compared with rubber, both TPVs exhibit lower levels of stress relaxation over a period of years, particularly at elevated temperatures. Both TPVs also make possible substantially greater productivity than rubber by eliminating the crosslinking step, by being pro- cessable on standard thermoplastic equipment with much less scrap, and by providing the capability of two-component mold- ing. 新型自润滑组合料：特诺尔艾佩斯公司（Teknor Apex） 发布了一种新的混合料，即用于制作管材接头密封的新型热塑 硫化橡胶（TPV）弹性体，其优点是可以采用同样的加工方式 获得超出热固性橡胶材料的性能。TPV作为一种成熟的物料， 具有更强的自润滑能力，有利于快速插入密封件并减少组装错 误。这种混合料将在K2016上展出。 Sarlink® 9156-02用于非承压管和排水管的接头密封， 所具有的物理特性几乎与坚实耐用的管材连接密封混合料 Sarlink® 9156B相同，但新材料Sarlink® 9156-02呈现出自润 滑特性，摩擦系数仅为原有的16% 。 特诺尔艾佩斯公司热塑弹性体部门销售总经理Stef Hor- dijk 说道：“新型材料Sarlink® 9156-02大幅度提高的自润滑能 力是其巨大的优势，向管件中插入连接密封件是一个机械过 程，在这一过程中，自润滑性加快了插入的速度并有利于防 止不良品。” 在施工现场采用人工方式连接管材时，带有自 润滑密封圈的管件同样有利于管材的插接。通过减小将管材 插入管件所需要的力量，自润滑特性有助于防止不正确的装 配对连接密封圈的损伤。 管材连接密封件必须能防止来自于管材内部的泄露以及 来自于外部的渗透。与Sarlink 9156B相同，新的自润滑组合 料显示出了在若干年内最大可能地保持密封性的特点，性能 优于橡胶，延长了管道连接密封的工作寿命。密封力是通过 应力松弛程度来测量的。与橡胶相比，经过若干年后，两种 TPV都呈现出较低的应力松弛水平，尤其是在温度较高的场 合。与橡胶相比，两种TPV都可以大幅度提高生产效率，可 以通过消除交联步骤，采用标准的热塑设备进行加工和减少 废料，以及通过提供双组份的能力来提高生产效率。 A new thermoplastic vulcanizate (TPV) elastomer for pipe seals exhibits the same processing and performance ad- vantages over thermoset rubber as a well-established TPV while providing enhanced lubricity for faster insertion of seals and more error-free assembly, it was announced by Teknor Apex Company, which introduced the compounds at K 2016. For use in seals for non-pressure water and drain pipe, Sarlink ® 9156-02 provides physical properties nearly identical to those 新型自润滑组合料 New Lubricated Compound 可看见密封圈的管件 Pipe fitting with seal visible
