Snow Heat Melting Agent for Cement Concrete Pavement
Snow Heat Melting Agent for Cement Concrete Pavement
(Eco-Friendly Deicer)
Snow melting agent for cement concrete pavement resolves the problem of corrosion to concrete pavement of traditional products and reduces the impact on roads and environment. With fast melting speed and comparable effect with sodium acetate snow melting agents, this product has no corrosion effect on carbon steel and aluminum alloy. Automatic generation of heat is adopted in this product and plant degradation reaction is also used. As a result, the volume for this product is only one tenth of ordinary products and wheel rolling is not required. After snow melting, magnesite grid is formed to reinforce the strength of the road. For secondary usage, the residue products can facilitate plants’ growth. With reasonable price, this product resolves the problem of high price of organic products.
