The Snow Agent of order just reaches hundreds of thousands ton, and the development of snow melting agent, production do not have scale, national manufacturer also in China
But five or six, the supply of goods only has tens of thousands of tons, much can not meet the demand in market.The Development and Production of Snow Agent possesses huge
Business opportunity.So active development efficient and environment-friendly type Snow Agent can not only meet national demand, and European market, shape can be squeezed into
Into new growth engines.
Snow Agent species is various at present, but has part not fully up to expectations.Traditional villaumite type snow melt based on sodium chloride
Agent raw material is cheap and easy to get, but environment is polluted, to road equipment seriously corroded；And having based on CMA (CMA)
Though machine Snow Agent has the characteristics of pollution-free, environmentally friendly, due to expensive starting materials, the thawing ability to snow is not so good as sodium chloride, snow melt
Limiting temperature be -12 DEG C, the shortcomings of dust and pungent tart flavour are formed during spreading, do not widely use.In order to solve with
Upper problem, a kind of efficient and environment-friendly type Snow Agent is developed, it is had, freezing point is low, and Rateof snowmelt is high, again to metal, mixed
Solidifying soil and bituminous paving are almost corrosion-free, and also small to plant hazard, i.e., environmental-protecting performance will get well, and the spies such as raw material is cheap and easy to get
Point, to meet the needs of domestic and international market is growing to Snow Agent.
The content of the invention
