The factors that affect the filling effect of nanometer calcium carbonate in rubber products


The factors that affect the filling effect of nanometer calcium carbonate in rubber mainly include the following six aspects: 1. Crystal in different crystalline nano calcium carbonate, the chain of nano-calcium carbonate on the rubber reinforcement effect is the best. 2. Particle size to 80-120nm is appropriate, the application of nano calcium carbonate in rubber, the finer particles, and rubber with each other more invasive surface area, so that the dispersion of calcium carbonate particles more and more difficult, especially below 80nm, Due to the increase in surface energy, easy to heat in the rubber mixing caused by sticky.
