| 1. | Preparation and characterization of kaolinte - potassium acetate intercalation comple 醋酸钾插层复合物的制备与表征 |
| 2. | The relative mass ratio of potassium acetate and water in the chemical reaction system must be controlled strictly for high intercalation rate 反应体系中,高岭土、乙酸钾和水的量都必须严格控制,才能获得比较满意的插层率。 |
| 3. | Different from potassium acetate , ammonium acetate intercalated into the inner layer of kaolinite more completely in buffer solution ( ph = 9 ) than under near dry condit ion 与乙酸钾不同,乙酸铵与高岭土的插层作用在ph = 9的缓冲溶液中,比在近干态下进行的完全。 |
| 4. | It only takes 24 hours to reach the maximum intercalation rate ( beyond 80 % ) when the relative mass ratio of kaolinite , potassium acetate and water is 7 : 3 : 1 实验发现,当高岭土、乙酸钾与水的比例为7 : 3 : 1时,只需24小时,就基本达到最大插层率(插层率超过80 ) 。 |
| 5. | Ft - ir spectrum show that water insert between the inner layer of kaolinite with potassium acetate , which form hydrogen bond with the inner surface hydroxyl of kaolinite 傅立叶变换红外光谱显示,水和乙酸钾一同插入到高岭土的层间,并与高岭土的内表面羟基形成了氢键。 |
| 6. | Research show that potassium acetate can directly insert between the inner layer of kaolinite under the participation of water , forming kaolinite / potassium acetate intercalation composites 研究发现,在水的参与下,乙酸钾可以直接插入高岭土层间,形成高岭土乙酸钾插层复合物。 |
| 7. | Potassium acetate adsorbed on the surface of kaolinite particle can be eluted by absolute ethyl alcohol , while that intercalated between the inner layer of kaolinite may not be affected 用无水乙醇作洗涤液可以将吸附在高岭土颗粒表面的乙酸钾洗脱除去,而已经插入高岭土层间的乙酸钾则不受影响。 |
| 8. | Second , ptfe composites were treated using different surface treatment methods . the adhesive strength tests were conducted by a standard experiment method . the maximum adhesive strength between ptfe and stainless steel was up to 5 . 63 mpa using the melting potassium acetate 利用不同的表面处理方法对ptfe进行表面改性,然后按标准试验方法进行粘接强度试验,结果表明,经过熔融醋酸钾处理的ptfe与钢的粘接强度最高,达到5 . 6mpa 。 |
