白炭黑是炭黑的一种重要替代品,是微细粉末状或超细粒子状无水及含水二氧化硅或硅酸盐类的统称。白炭黑是橡胶制品的重要补强填充剂,它能提高胶料的物理性能、减少胶料滞后、降低轮胎的滚动阻力,同时不损失其抗湿滑性。在高档彩色橡胶制品中,其补强效果可以达到炭黑的水平。在轮胎工业中,在胎面胶中添加白炭黑可以提高胎面 Silica is an important alternative to carbon black and is a collective term for finely powdered or ultrafine particulate anhydrous and hydrous silicas or silicates. Silica is an important reinforcing filler for rubber products. It increases the physical properties of rubber compounds, reduces the lagging of rubber compounds and reduces the rolling resistance of tires without losing their wet skid resistance. In high-grade color rubber products, its reinforcing effect can reach the level of carbon black. In the tire industry, the addition of silica to the tread band can increase the tread
