白炭黑又称轻质二氧化硅。 分子式：SiO2 nH2O 性质：白碳黑是白色无定形蓬松粉状物，是一种多孔性搞分散并有的吸水性。产品无毒无气味，主要成份为SiO2，多孔性，内表面积大，不溶于酸和水，溶于苛性碱及氢氟酸，受高温不分解，在空气中易潮解。 在农药工业中是良好的填充剂，特别能提高可湿性农药分散性和吸附力。 *白碳黑填充于橡胶和塑料工业中能提高橡胶和塑料制品的各种物理性能，绝缘性能良好，也能作为药物活性成分载体，乳浊液的稳定性。*在树脂中作为硅脂的原料，掺入环氧树脂后，能防止收缩作用，用于酚醛胶布及玻璃中可以改善各种产品的物理性能。*广泛用于涂料，合成皮革，医药等方面。 |
The English version
White carbon black, also known as lightweight silica.
Molecular formula: SiO2 nH2O
Properties: white amorphous carbon black is white fluffy powder, is a kind of porous dispersion and strong water imbibition. Products non-toxic odorless, main composition is SiO2, porosity, large surface area, insoluble in water and acid, soluble in caustic and hydrofluoric acid, the high temperature decomposition, easy deliquescence in the air.
In the pesticide industry is good filler, especially could improve the wettability of pesticide dispersion and adsorption.
* white carbon black filled in rubber and plastic industry can improve the physical performance of rubber and plastic products, insulation performance is good, also can active ingredient as a drug carrier, the stability of the emulsion. * in the resin as raw material of silicone, mixed with epoxy resin, can prevent the contraction, used in the phenolic adhesive and glass can improve the physical properties of various kinds of products. * widely used in coating, synthetic leather, medicine, etc.
