摘要
以潍坊产天然钙基膨润土为原料经锂基改性后,制备出锂基膨润土。以锂基膨润土为辅料配制铸型涂料,所得涂料不仅发气量低,而且其粘度、悬浮性和抗急热开裂性等指标表现优异。将涂料涂覆于型砂表面进行实际测试,涂料表现出抗粘砂性强,附着强度高,浇注后涂层易剥离,铸件表面光滑的特点。
Natural Ca-bentonite in Weifang was modified into Li-bentonite which was applied as a component to prepare mold coatings. In addition to low gas emission, the product shows low viscosity, good suspension and resistance to sudden heat cracking.
