保定消光粉厂

消光粉要达到消光效果，必须在漆膜的表面造成光线漫反射，否则消光效果不好。

To achieve matting effect, we must create light diffuse reflection on the surface of paint film, otherwise the extinction effect is not good.

因此，消光粉尽量不要研磨，如果研磨或者高速长时间分散，会将消光粉的表面破坏，而且粒径也变太小了，这样的消光效果不理想。

Therefore, the extinction powder is not abrasive as far as possible. If the grinding or high speed is dispersed for a long time, the surface of the powder will be destroyed and the particle size is too small, so the extinction effect is not ideal.

目前市场上的消光粉的粒径不会大于30微米，对于一般的面漆来说，已经足够了，消光粉一般不研磨的原因是消光粉自身的海绵状结构，过度研磨（或者分散）会破坏海绵状结构，形成光滑的切面，造成消光效率下降。

At present, the particle size of the extinction powder on the market will not be more than 30 microns. For the general surface paint, it is enough. The reason for the general non grinding of the powder is the sponge like structure of the powder. The excessive lapping (or dispersion) will destroy the sponge like structure and form a smooth cutting surface, resulting in the decrease of the extinction efficiency.

消光粉研磨的话，消光能力会有影响的，一般消光粉的粒径在5-20um，不会对表面产生影响，如果有影响的话，加入时的步骤（在搅拌时加入）和油漆的粘度可以适当低点，除非消光粉的分散能力差，否则分散15~30min就达到要求。

The extinction powder is abrasive, the extinction ability will have influence, the general extinction powder particle size in 5-20um, will not affect the surface, if there is influence, the step (in agitation when added) and the viscosity of the paint can be low, unless the dispersing capacity of the powder is poor, otherwise the dispersion of 15~30min will meet the requirements.
