The results show that in alkaline medium, the separation of diaspore from the other three silicate minerals by reverse flotation can be realized by using quaternary ammonium salts as collectors; 结果表明:在碱性条件下,以季铵盐为捕收剂可实现一水硬铝石与3种硅酸盐矿物的反浮选分离;
This paper deals with a kind of high efficient and nontoxic antifouling paint with alkaline silicate as the main antifouling composition and used in the netting of marine cage. 本文以碱性硅酸盐为主防污剂,开发了一种防污期长、无毒、环保且高效的海水网箱网衣防污涂料。
Under the alkaline condition, the synthesis of mesoporous molecular sieves MCM-41 had been accomplished successfully in a hydrothermal system using sodium silicate as the source of silicon and surfactant C16H33 ( CH3) 3NBr as structural template. 在碱性条件下,采用水热晶化法,以水玻璃为硅源,表面活性剂十六烷基三甲基溴化铵为结构模板剂,成功合成出全硅MCM-41中孔分子筛。
Aluminum silicate fiber resistant acid and alkaline, and resistant corrosion and have chemical stability strongly. Aluminum silicate fiber as packing, adding to less than 10%, can achieve the required index basically strength and intensity. 硅酸铝纤维耐酸碱、抗腐蚀,化学稳定性强;硅酸铝纤维作为填料,添加量控制在10%以内,基本能够达到强度要求,且强度指标基本上保持不变。
