Is industrial salt used as a snow melting agent?

  It is mainly the effect of heavy metal ions in industrial salt, because the melted snow water mainly penetrates into groundwater, or infiltrates into soil or flows into rivers, so you can control the impact of heavy metals on soil and water bodies.

  In addition to heavy metal ions, some of the monovalent, such as NA, K too much will also affect the growth of soil vegetation.

  At the same time, the change of sulfate ions is also acidic in snow, which directly affects the quality of roads and tires.

  1. The devastating blows to farmland and greenery along the roads.

  After the snow-melting agent is used, the snow is often accumulated on the green belts or farmland on both sides of the road. After the spring, all the salt residues are accumulated in the farmland and green belts. The crops and trees are afraid of salt, which will cause a large number of green plants to die. Destructive. Even if it is replanted, all soil must be replaced, and the farmland is even more vulnerable to escape! The loss is self-evident.

Because the northern land generally contains salt, the northern plants themselves can resist salt and alkali, even if it is difficult to withstand the harm caused by the snow melting agent, not to mention the southern sour soil plants, can not bear the harm caused by saline.

  2, shorten the road life.

  Especially for asphalt concrete pavements, salt substances and bitumen will have a chemical reaction, which will greatly reduce the ability of bituminous materials and sand stone materials to grip and cause the asphalt surface to fall off. Under the effect of vehicle loads, a large area of pavement will be damaged.

  After salt meets water, salt rise will occur, which will result in road subgrade damage. This will directly lead to the end of the road, which will greatly increase the difficulty of road maintenance in the later period.

  Salts also have a similar hazard to cement concrete pavements. The reason is simple. Cement concrete pavements on urban roads will not use expensive salt-resistant cement on one side.

  Snow melting agents such as NaCl and iron and other metals on the roadbed form primary batteries to accelerate road damage.

  3, pollution of the environment

  The commonly used snow melting agents are based on salts. Nowadays, the environmental protection snow melting agents on the market are all deceptive. After entering the underground, salt substances are bound to pollute the local groundwater resources. The consumption of water contaminated with snow melting agents will cause serious harm to human health.

  Therefore, it is currently the best choice to choose snow melting agent to remove snow and ice in the market. There are many types of snow melting agent. Relatively speaking, the current environmental snow melting agent is mainly composed of sodium chloride, which is more environmentally friendly than industrial salt. Environmentally-friendly snow melting agents have little or no corrosiveness on municipal roads, but they do have many harmful effects on plants. At present, the two kinds of environmental-friendly snow melting agents, uns6-1 and uns6-2, are more commonly used, and these belong to the category of common snow melting agents.
