Siliconed_wollastonite (No1)

Wollastonite was past the local substitute for asbestos and filling has already been applied in the friction material. Here are the modified wollastonite is to wollastonite surface treated with coupling agent Choude products. Modified wollastonite and wollastonite ore than have the same good heat resistance and has an enhanced effect in fact other than the appearance, handle, pay to have improved to some extent. Particle films on the surface of a coupling agent covering the original form of wollastonite played a very good protective effect, resulting in wetting sense of needle-shaped fibers can be identified clearly from the more favorable dispersion and mixing enhancement. More importantly,
Since both the surface modified wollastonite combination with inorganic materials, functional groups, there can be combined with the functional groups of organic materials, fits both organic binder and inorganic filler both the technical requirements of the friction material, with a variety of fully compatible components in the local enhancement, temperature effects, the role of friction performance aspects are better than the original ore wollastonite銆
