由黑龙江省低温建筑科学研究所研制成功的新型“碳酸盐防冻剂”利用工业付产品碳酸钾钠为主要原料复合而成。开辟了一条生产混凝土防冻剂原料的新途径。该防冻剂掺量较少,不含氯盐,对钢筋无锈蚀作用, The new “carbonate antifreeze” developed by the Heilongjiang Institute of Low-temperature Construction Science and Technology was produced by using industrial sodium carbonate as the main raw material. Opened a new way of producing concrete antifreeze raw materials. The antifreeze has less addition amount, does not contain chlorine salt, and has no rusting effect on steel bars.
