为了在不损失强度的同时获得较高的填料含量,在工厂进行了由淀粉封装(encapsulated)的高岭土颗粒组成的改性填料试验。该研究在实验室进行了表面涂布应用实验,考察了经淀粉处理过的颜料提升强度的潜在优势。研究发现,与细高岭土比较,单位质量下板状高岭土涂层的强度提升幅度大,而板状高岭土经过淀粉封装以后,涂层强度提升幅度则更大;从强度提升角度看,将淀粉按照等当质量比例添加到高岭土配方混合液中,其提升量不及淀粉封装高岭土的。
In order to obtain a higher filler content without losing strength, a modified filler test consisting of starch encapsulated kaolin particles was conducted at the factory. The study was conducted in the laboratory surface coating application experiments investigated the potential advantages of starch-treated pigments to enhance strength. The results show that, compared with fine kaolin, the strength of plate kaolin coating per unit mass is greatly increased, while the plate kaolin after starch coating, the coating strength increase is even greater; from the perspective of enhancing the strength, the starch in accordance with the When the mass ratio is added to the mixed solution of kaolin, the amount of its lifting is less than that of starch encapsulated kaolin.
