如果把喷砂机工用过的废砂用细筛子(根据要求不同,可取100号、120号、140号、200号……等)选取后,跟工业用的凡士林机油配制成磨料就可以代替凡尔砂。如果将废砂轮用电辗子研成细粒再用细筛子选取后来配制就更好了。配制成分的比例应根据不同季节决定。在冬季可按:砂子60％、凡士林20％、机油20％;在夏季可按:砂子70％、凡士林20％、机油10％。使用时如果太厚或太薄,可酌情增减砂子或油脂。
If the sand blasting machine used waste sand with a fine sieve (according to different requirements, preferably 100, 120, 140, 200, etc. ...) selected, with industrial Vaseline oil formulated into abrasive material can be replaced Where Er Sha. If the waste wheel grinding roller grinding into fine and then fine sieve selection is better prepared later. The proportion of formulated ingredients should be based on different seasons. In winter can be: sand 60%, petroleum jelly 20%, oil 20%; in summer can be: sand 70%, petroleum jelly 20%, oil 10%. If you use too thick or too thin, the discretional increase or decrease of sand or grease.
