The multiporous cellulose is a special functional material of friction material, it takes the selected lignin straw as a raw material, adopts an optimization process, and fully eliminates the impurities such as lignin.
The multiporous cellulose is a special functional material of friction material, it takes the selected lignin straw as a raw material, adopts an optimization process, and fully eliminates the impurities such as lignin, pectin in the raw materials through a plurality of processes, so as to obtain the extremely pure cellulose product. Porous cellulose has micro-porous structure in physical morphology. The porous cellulose has the characteristics of low density, high porosity, low ash content, light appearance color and so on. It has certain chemical activity and has good temperature-resistant property.
Multiporus cellulose is especially suitable for low noise, low dust, low density friction materials and light-colored ceramic friction materials, which can partly replace nitrile rubber powder, friction powder, and Cellulose fiber and other traditional friction materials, The addition of this product to the friction material can make it easy to mix, reduce the compression ratio and reduce the pollution of powdered phenol and formaldehyde.. Suitable for the manufacture of disc brake, drum brake plate and clutch disc, it can reduce braking noise, stabilize friction and wear performance, and improve driving speed.
