对河南西峡县桑坪纤维状海泡石进行了加热、研磨、盐酸、氢氧化钠处理试验。加热到300℃时晶体结构发生了折叠。研磨4h 后晶体结构有产生折叠的趋势。用20%的盐酸处理过的海泡石表面开始出现缺陷,表明其耐酸性能较差。不同浓度的氢氧化钠处理后的海泡石结构变化不大,说明其耐碱性能良好。 Xixia County, Henan Province, Sangpine fibrous sepiolite heating, grinding, hydrochloric acid, sodium hydroxide treatment experiments. The crystal structure is folded when heated to 300 ° C. After grinding for 4h, the crystal structure tends to fold. The sepiolite surface treated with 20% hydrochloric acid began to show defects, indicating poor acid resistance. The results showed that the structure of sepiolite treated with different concentrations of sodium hydroxide did not change much, indicating that its alkali resistance is good.
