Abstract

The antifreezing powder specially for coal and ore consists of calcium chloride dihydrate, corrosion inhibitor, antirusting agent, skidproof agent, adhesive and ammonia water, and is prepared through crushing, mixing, forming powder, and adding ammonia to result in pH 7-9. It is used for winter transportation of coal and ore powder to prevent freezing. It has the advantages of high efficiency, low freezing point, high dissolvability, less corrosion and low cost.

Description

Technical field: [0001] The invention relates to a special antifreeze powder, in particular to a special antifreeze powder mainly used for antifreezing of coal and ore dressing powder, which is suitable for industries such as coal and ore dressing powder. Background technique: [0002] At present, in the process of transporting coal or ore powder by train in winter in our country, due to the freezing of coal, ore powder itself and wagons, it has caused many difficulties to transport units and users, causing many unnecessary economic losses. In order to solve this problem , the special antifreeze powder we developed for coal and ore is of great significance. Invention content: [0003] The object of the present invention is to provide a special antifreeze powder for coal and ore dressing powder which is used to prevent coal, ore dressing powder itself from freezing or prevent coal, ore dressing powder and wagons from freezing during transportation. [0004] The object of t...
