Silica is one of the most important new high-tech ultrafine inorganic materials. Due to its small size, it has the characteristics of large specific surface area, strong surface adsorption, large surface energy, high chemical purity, good dispersion performance, heat resistance and electrical resistance. It has special properties, especially its superior stability, thickening and thixotropy. So today, let’s talk about the content of white carbon black in nylon conveyor belts.

As a component of the m-methyl white rubber system, it can not only improve the adhesion between rubber and metal, but also give vulcanized rubber good wear resistance, heat build-up, tear strength and fatigue resistance. Therefore, it is added to rubber The right amount of white carbon black is necessary.

It can be seen that the amount of silica affects the performance of the rubber compound. It can be seen that adding an appropriate amount of silica to the rubber compound can significantly improve the bonding strength of the rubber compound and brass, so silica plays an important role in the bonding system.

This is because the silanol groups on the surface of the white carbon black can chemically bind water and are evenly distributed throughout the rubber compound, reducing the concentration of water at the rubber and brass interface, thereby effectively preventing water from destroying the bonding structure. Silica helps the methylene donor and methylene acceptor diffuse to the bonding interface. The acidity of the surface of silica silanol can delay vulcanization, keep the rubber flowing for a long time, give the rubber enough time to diffuse to the surface of the brass, and increase the contact area between the rubber and the brass.
