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、带有一定过剩负层电荷的2∶1型层状
JS-inorganic gel is a new type of mineral colloidal material developed by Jiangsu Institute of Geology and Mineral Testing and Application. It is mainly composed of silicon, magnesium, lithium, aluminum and other elements, and its chemical structure formula is [(Mg 2.67) Li 0.21 Al 0.05 Fe 0.01 0.01 Si 3.98 Al 0.02 O 10, (OH, F) _2] Na_ (0.18) Li_ (0.07) Ca_ (0.04), which has great gelling ability in water. The thixotropic gel can be formed by formulating 1-5% aqueous dispersion. Its appearance and colloidal properties than the United States Vanderbilt’s Veegum-F products. JS-Inorganic gels are 2: 1 type layered structures having an expandable structure with a certain amount of excess negative layer charge
