| 摘 要： | 研究了不同基料、空心微珠填料尺寸、涂料涂层厚度和温度对涂料高温绝热性能的影响.发现以E800黏结剂为基料，涂层厚度为0.42mm时，就已经达到了最佳绝热效果.以水玻璃溶液为基料，配以0.5%羧甲基纤维素的涂料绝热性能最佳；PA80型高温胶对钢板有强烈腐蚀作用，因而不适合成为高温绝热涂料的组成成分；在涂层厚度和基料相同的情况下，构成涂料的空心陶瓷微珠填料粒度越小，高温绝热性能越好.选用5000目粒度的空心陶瓷微珠填料、水玻璃溶液为基料配0.5%的羧甲基纤维素构成的绝热涂料，在冶金企业30t的钢包内涂刷0.8mm后，钢包内钢水每分钟的平均温降比不刷本绝热涂料时低0.41℃，可以直接为冶金企业带来经济效益.

| Abstract: | The heat-insulating properties of heat insulating coatings were studied by adding different coating binders and changing micro bead size,temperature and coating thickness. It is found that the optimal adiabatic effect is obtained when the thickness of E800 binder based coatings is 0.42 mm. PA80 high-temperature gel is not suitable to be used in heat insulation coatings for its strong corrosive effect. Experimental results show that the coatings in the best adiabatic effect are based on soluble glass dissolved with 0.5% carboxymethyl cellulose. The smaller the micro bead size is,the better the heat-insulating properties of the coatings with the same thickness and binder are. The coating with the components of 5000 mesh micro beads and soluble glass based 0.5% carboxymethyl cellulose was chosen to paint on the steel ladle in-wall. The temperature drop per minute of the steel ladle with a 0.8 mm coating is 0.41℃ less than that without the coating. It is indicated that this coating is suitable to be implemented. |
