这种水合无定形白炭黑是在水介质中用矿石酸中和碱性硅酸盐制得后，经过再次表面处理。该产品有着良好的分散性、消光性，可用于各类涂料的消光，同时由于该产品的透明性对颜料的色泽影响不大，可用于各种有色产品的消光。

TQ-312L is used in the coating industry and has a matting effect. This hydrated amorphous silica is prepared by neutralizing alkaline silicate with mineral acid in an aqueous medium, and then surface-treated again. The product has good dispersibility and matting properties, and can be used for matting of various coatings. At the same time, because the transparency of the product has little effect on the color and luster of pigments, it can be used for matting of various colored products.
