Method of making hydrated kaolin clay and products made
Disclosed herein are methods of forming a hydrated kaolin clay product. The method may include: (i) refining a coarse raw kaolin clay to form a refined coarse kaolin clay, and/or refining a tertiary fine raw kaolin clay to form a refined fine hydrated kaolin clay; (ii) centrifuging the refined crude kaolin clay, the refined fine hydrated kaolin clay, or a blend thereof to provide a hydrated kaolin stream; and (iii) refining the hydrated kaolin stream to form a hydrated kaolin clay product. The hydrated kaolin stream may be blended with the layered crude kaolin clay prior to refining the hydrated kaolin clay stream. The hydrated kaolin clay product may have a total alkali metal content of 0.2 wt% or less based on the hydrated kaolin clay product. Also disclosed herein are compositions comprising the hydrated kaolin clay product, including cordierite ceramics, industrial coatings, paints, adhesives, inks, and fillers.
本文公开了形成水合高岭土粘土产物的方法。此方法可以包括：(i)精制粗的原高岭土粘土以形成经精制的粗高岭土粘土，和/或精制三级细的原高岭土粘土以形成经精制的细水合高岭土粘土；(ii)经精制的粗高岭土粘土、经精制的细水合高岭土粘土或它们的共混物进行离心以提供水合高岭土料流；和(iii)精制水合高岭土料流以形成水合高岭土粘土产物。水合高岭土料流可以在精制水合高岭土粘土料流之前与已分层的粗高岭土粘土共混。水合高岭土粘土产物可以具有基于水合高岭土粘土产物计的0.2重量％或更小的总碱金属含量。本文也公开包含水合高岭土粘土产物的组合物，包括堇青石陶瓷、工业涂料、油漆、粘合剂、油墨和填料。
