The Principle of Dispersants
Adsorbed on the surface of the solid particles, making the surfaceof agglomerated solid particles easy to wet. The polymer dispersant on the surface of the solid particles forming the adsorption layer, the surface of the solid particles of the charge is increased to improve the particle formation reaction between the steric hindrance. The solid particles […]
What is the role of zinc oxide in rubber formulations?
First, activate the entire curing system Zinc oxide and stearic acid together form zinc soap, improve the solubility of zinc oxide in the compound, and with the accelerator to form a complex, this complex is particularly lively, it reacts with sulfur to produce a very strong vulcanizing agent. Second, improve the cross-linking density Zinc oxide […]
