軟研磨料是由具有拋光性的各種物質所制成的粉末或軟膏,其中包括氧化铁、氧化鉻、氧化鋁、氧化鉛、矽藻土、硅藻土及其他許多有机物。在機械制造業上最通用的是氧化铁、氧化鉻及氧化鋁。現在使用得最廣泛的是ΓОИ軟膏。ΓОИ軟膏是在列寧恪勒国立光學学院指導下由專门的工廠製造的。這類軟膏是科学院院士Гребенвщнков的工作成績,它的主要成分是含有硫的氧化鉻。製造氧化铬的方法是:把重鉻酸钾(100份按重量計)及硫(30份按重量計)混合,加热到硫
Soft abrasive is a powder or ointment made of various materials with polishing properties, including iron oxide, chromium oxide, aluminum oxide, lead oxide, diatomaceous earth, diatomaceous earth, and many other organic materials. The most common in the machinery manufacturing industry are iron oxide, chromium oxide and aluminum oxide. Now the most widely used is ΓОИ ointment. ΓОИ Ointment was manufactured by a dedicated factory under the direction of Leninkeler State Optical Academy. This type of ointment is a result of the academician Гребенвщнков, whose main constituent is chromium oxide containing sulfur. The chromium oxide is made by mixing potassium dichromate (100 parts by weight) and sulfur (30 parts by weight) and heating to sulfur
