尼龙球
静电亚导体尼龙球"触摸式人体静电释放报警器"
亚导体在任何情况下,其体积电阻率大于1×10Ω·m而小于1×10Ω·m。(即电导率小于1×10S/m而大于1×10S/m),或其表面电阻率大于1×10Ω而小于1×10Ω。
静电亚导体是介于导体和非导体之间的材料,其表面电阻率大于1*106Ω小于1*109Ω。
在电荷泄漏时,因为亚导体具有较高电阻率,其泄漏电流十分微弱,处于μA极,不会产生瞬间电击现象,避免因电火花引爆可燃性气体,从而达到导电防爆的目的,更适用于易燃易爆等危险防爆环境,如加油站、石油库等对静电特别敏感的场所。

Nylon is a generic title for a group of synthetic polymers known generically as polyamides, Solid nylon is used for mechanical parts such as machine screws, gears and other low- to medium-stress components formerly cast in metal. Engineering-grade nylon is developed by extrusion, casting, and injection molding. Type 6, 6 Nylon 101 is the most common commercial grade of nylon, and Nylon 6 is the most common commercial grade of molded nylon.
The melting point of nylon 6, 6 is 509oF (265oC).
