Use & application method

1. Use 1)Produce concrete antifreezer: Calcium nitrite has high solubility, so can be made into solution or powder as demands. Using this antifreezer at negative temperature can promote the hydration of minerals in cement, and the freezing point of operative temperature can be reduced to -20C. 2)Produce steel rust inhibitor: Calcium nitrite can purify steel and protect it from rust, and can protect steel material in concrete buildings and structures from rust, to extend the useful life of concrete buildings. 3)Produce concrete coagulator: Calcium nitrite is free of chlorine and alkali, capable to reduce alkali aggregation of concrete and improve its early strength and compressive resistance. 4)Calcium nitrite can be sued as corrosion inhibitor for lubricating agent.
