Abstract

The invention relates to a snowmelt agent, which is a composite snowmelt agent and comprises the following components and contents (weight) in percentage by weight: 80 to 95 percent of acetate and 5 to 20 percent of chloride. Compared with the prior art, the snowmelt agent has good snow removing effect and low chloride content, can reduce the corrosivity of the snowmelt agent obviously, effectively protects pavement and bridges, prolongs the service life of public facilities and reduces the cost while achieving excellent snow removing effect.

Description

technical field [0001] The invention relates to snow removal materials, in particular to a snow melting agent. Background technique [0002] At present, the deicing agents are mainly chlorine-salt deicing agents, including sodium chloride, potassium chloride, calcium chloride, magnesium chloride, etc. These deicing agents absorb heat through the dissolution of salts on the one hand to remove snow, and on the other hand use salt water The freezing point is low, and it is difficult to form ice cubes after the salt is dissolved in snow water, which is conducive to snow removal. This kind of deicing agent is cheap and can be widely used, but it is highly corrosive, easily corrodes metal and concrete, etc., and seriously damages large-scale public infrastructure. Contents of the invention [0003] The object of the present invention is to provide a snow-melting agent with low corrosion and good snow removal effect in order to overcome the defects of the above-mentioned prior a...
