JS—无机凝胶的特性和工业应用

Properties and Industrial Application of JS-type Inorganic Gel

JS-无机凝胶是江苏省地质矿产测试应用研究所研制的一种新型矿物胶体原料。它主要由硅、镁、锂、铝等元素组成,其化学结构式为[(Mg_(2.67)Li_(0.21)Al_(0.05)Fe_(0.01))Si_(3.98)Al_(0.02))O_(10)(OH,F)_2]Na_(0.18)Li_(0.07)Ca_(0.04),它在水中具有极大的成胶性能,配制成1—5％的水分散液就能形成触变性凝胶。其外观和胶体性能优于美国范德比尔特公司的Veegum-F产品。JS-无机凝胶是具有可膨胀结构。

Js—inorganic gel composed mainly of silica. magnesium. lithium and aluminum elements, is a new raw material of mineral gel. It is characteristic of great gel-forming ability, expansion structure, unsaturated filling of tri-octahedron-octahedron and laminate irregularity. Its aqueous solution has a lot of perfect properties such as colloidal dispersion, suspension, thickening, thixotrppic, adsorption and cation exchange capacities. In the product aspect and colloidal properties the Js-inorganic gel is prefer to that of Veegum-F product made in the U. S. In the composition of formula, the quantity of JS-type gel is about 0. 5—4 per cent, sometimes 7-10 per cent. In the industrial application JS-type gel could be used in many ways, for example emulsion paint, non-drip paint, electrolytic deposit paint and cosmetic goods and antistatic agent, porcelain glaze, sticking agent, decontaminating agent. printing aid and lithium battery. The physical properties of JS-type gel are mainly determined by its atomic structure and its industrial usages normaly related with the structure. Now, test results illustrate that JS-type gel has good performance for the improvement of cosmetic goods and high molecular compounds and wide application in other industrial fields.
