The clay
Also known as kaolin clay, it is a kind of fine grinding of kaolin, mainly consists of kaolinite is build by laying bricks or stones grinding and become, called the neutral clay. Its main ingredient is silicon aluminum alum, kaolinite
Is a regular clay minerals, and a second water aluminum silicate, a fraction of Al2Si2O5 (OH) 4, consisted of a tetrahedral coordination of silicon and oxygen molecules, and octahedral coordination of aluminium sharing again, basically have no substitutes.
Applicable industry:
Polymer coatings, adhesives, rubber and other industries, and the mixture in the rubber industry has very good reinforcement effect, this is the general kaolin can not meet the domestic level. PH value: 5.0
