目前国内销售的融雪剂大致分两类:以“氯盐”为主要成分的无机融雪剂,尽管价格便宜,对公路桥梁的腐蚀却很严重,通常就是我们常说的“工业盐”;以醋酸钾为主要成分的有机融雪剂,基本没有腐蚀性,但价格过高,一般用于机场等重要场所。专题开头提及的新疆伊犁州公路局坦言,由于融雪剂用量太大,售价太高的有机融雪剂专用于高速公路和重点桥梁,普通公路仍然使用每吨售价几百元的工业盐。这种尴尬并非个案。成本,已成为公路部门采购融雪剂时的关键标尺。 Currently sold in China deicing salt broadly divided into two categories: “Chloride salt ” as the main component of inorganic deicing salt, despite the cheap, the corrosion of highway bridges is very serious, usually we often say "industrial salt Organic deicing salt with potassium acetate as the main component is basically non-corrosive, but the price is too high and is generally used in important places such as airports. As mentioned at the beginning of the project, the Yili Prefecture Highway Bureau said that due to the excessive amount of deicing salt and the too high price of organic deicing salt, it is mainly used on expressways and key bridges. Ordinary roads still use industrial salt at a price of several hundred yuan per ton. This embarrassment is not the case. Cost has become a key yardstick for highway agencies purchasing deicing salts.
