What is the difference between using sodium chloride and calcium chloride as snow melting agents?
Winter snow days which bring inconvenience to people's travel or work life, then people use calcium chloride as a snow melting agent, clear the snow on the road, melt the ice on the road; the national standard calcium chloride snow melting agent content of 74%, low price, fast snow melting, small dose, dissolved products can promote plant growth, steel and other metals and bridge cement concrete corrosion is tiny.
The raw material used in the traditional chlorine-type snow melting product is sodium chloride, although sodium chloride is easy to obtain and cheap, but it will cause different degrees of harm to the environment, and the corrosion hazards of road facilities are more severe, so slowly do not use sodium chloride as a snow melting raw material, and gradually use calcium chloride to replace it, this is because calcium chloride can reduce the freezing point of ice and snow while minimizing the harm to road facilities; calcium chloride will release heat when dissolved, and no sodium ions are stored in the soil; the degree of pollution to the environment is light The price of calcium chloride and the price of sodium chloride are not much different. Therefore, calcium chloride is good as a snow melting agent.
