本文叙述了锂膨润土悬浮剂及其配制的优质防粘砂醇基快干涂料的性能,以及在湿型生产拖拉机铸件上的应用。采用该涂料后,使铸件表面质量提高1～2级:铸铁件表面粗糙度Ra值达到6.3～12.5微米;铸钢件的达12.5～25微米。
This article describes the performance of lithium bentonite suspending agents and their formulated high-performance anti-sticking sand alcohol-based quick-drying coatings, as well as the application of wet-type tractor castings. After using the paint, the quality of the surface of the casting is improved by 1 ~ 2 grades: the surface roughness of the iron casting reaches the value of Ra of 6.3-12.5 microns; the steel casting reaches 12.5-25 microns.
