在涂料中的作用
1、超细硅酸铝替代部分钛白粉，其干膜遮盖力不会改变，并能提高漆的白度。若钛白粉的用量不变，其干膜遮盖力明显提高，白度大幅度提高。
2、超细硅酸铝ph值范围为9.7-10.8，其具有ph值缓冲作用。尤其在醋酸乙烯乳胶漆储存过程中能防止因醋酸乙烯水解而使ph值下降的现象，增加了乳胶漆的分散稳定性，同时避免了金属容器内壁遭受腐蚀。
3、硅酸铝的超细、网格结构使乳胶漆体系稍增稠，具有很好的悬浮性，并防止固体份的沉底及表面分水现象的出现。
4、超细硅酸铝使乳胶漆膜有很好的耐擦洗性、耐候性、另外能缩短表干时间。
5、超细硅酸铝有消光作用，所以在半光、无光漆中可以作为一种经济的消光剂，在有光漆中不宜使用。

aluminum silicate
in the coating
1, replace part of titanium dioxide superfine aluminum silicate, dry film covering power won\'t change, and can improve the whiteness of paint. if the amount of titanium dioxide, obviously improve the dry film covering power, greatly improve whiteness.
2, super fine aluminum silicate ph range of 9.7-10.8, it has a ph buffer. especially in vinyl acetate latex paint storage process can prevent the decrease of ph values resulting from vinyl acetate hydrolysis phenomenon, and increases the dispersion stability of emulsioni paint, at the same time to avoid the metal container walls subjected to corrosion.
3, super fine aluminum silicate slightly thickening, grid structure makes the emulsioni paint system, has the very good suspension property, and prevent the sink of solids and surface water.
4, ultra-fine aluminum silicate to scrubbing resistance of latex paint film has good table dry, weatherability, and can shorten the time.
5, ultra-fine aluminum silicate has extinction effect, so in the half light, matt can serve as a kind of economic delustering agent, in a light paint should not be used.
