长期以来我厂铝合金压铸件使用水剂胶体石墨涂料,虽有大量的优点,但如果此压铸件成品不上漆或不表面处理,则遇潮即会发生严重发黑,并且该涂料较易堆积,不利文明生产,因此我厂有关部门对此非常关心,并把它作为攻关项目,限期解决。经过多次试验,在1979年3月中旬起试验了“肥皂滑石粉铝合金压铸涂料”,并于79年6月1日起正式将此种涂料用于我厂铝合金的各种压铸件,不再使用水剂胶体石墨,到79年9月底已生产了四缸下体等各类压铸件四万四千余件。这种涂料具有:(1)脱模性能(高温润滑性)良好;(2)发气性很小;(3)不易引起堆积;(4)模具易于清洗,使用过程中模具只要用水洗
For a long time our factory aluminum alloy die-casting using water-based colloidal graphite coating, although a large number of advantages, but if the finished die-casting products are not painted or surface treatment, then the event that serious blackout, and the paint easier Accumulation, unfavorable civilized production, so I plant the department concerned about this, and it as a research project, a deadline to solve. After several tests, in mid-March 1979 from the trial of the “soap talcum aluminum die-casting paint,” and in June 1, 79 from the official this kind of coating used in various aluminum alloy die-casting parts, No longer use liquid glue colloidal graphite, to the end of September 79 has produced four-cylinder lower body and other types of die-casting pieces more than 44,000 pieces. The paint has: (1) release performance (high temperature lubricity) is good; (2) gas is very small; (3) is not easy to cause accumulation; (4) easy to clean the mold, the mold used in the process as long as water
