Basic Information
Snow melting agent refers to a chemical that can lower the temperature of melting snow and ice. It is a chemical. Ordinary snow melting agent raw materials are easy to obtain, and the price is low. The main components are potassium acetate and chloride salts, and are classified by the two types. The snow melting agent melts the snow on the road by melting the snow and melts the temperature, which is convenient for road dredging. The effect of the spreading is obvious, but it is harmful. It is found that the snow melting agent residue can corrode the road surface and the automobile rubber tire. At present, in the north, the sand and snow shovels are still mainly used in the winter, and the snow melting agent is used as a supplement to clear the road ice and snow to ensure smooth traffic.
There are many kinds of snow melting agents, which are divided into solid and liquid according to the state of matter; the composition is divided into inorganic matter and inorganic matter and organic matter, and the mixture of inorganic matter and organic matter is the most, and environmentally friendly snow melting agent is mostly not included. Or a mixture of chemicals such as MgCl2- with less chlorine; it can also be classified according to different uses. Generally, the quality of urban roads is low. The quality requirements for bridges and airports are high, but the quality must meet the standards.
Kinds
One type is organic snow melting agent with potassium acetate as the main component. The snow melting agent has good snow melting effect and basically no corrosion damage, but its price is too
high, and it is generally used in important places such as airports.
The other type is an inorganic snow melting agent containing "chlorine salt" as a main component, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride, etc., commonly known as 'icing ice salt'. The advantage is that it is cheap, only 1/10 of the organic snow melting agent, but it is very serious for the corrosion of large public infrastructure. Our common snow melting agent belongs to this category, the most used is sodium chloride (ie industrial salt)

Product performance:
1. In the case of low temperature weather, the effect of snow melting, snow removal and ice making is outstanding.
2. This product is non-toxic, odorless and has no pollution to the environment.
3. This product is white or slightly yellow particles or flakes.
4. This product has fire resistance.
5. The melting speed of this product is fast, energy-efficient, environmentally friendly, low freezing point, not easy to secondary icing, and the damage to the environment is reduced by nearly 20 times compared with ordinary snow melting agent, prolonging the service life of the road. It not only has no corrosion damage to the bridge, but also repairs the cracks on the pavement to strengthen the pavement strength and form an effective protection for the pavement. Technically, our snow melting agent has achieved zero corrosion to carbon steel. In the absence of external forces such as sun exposure or wheel rolling, even in the night and in the dull tunnel, it can generate high heat and rapid deicing. The melted product has been proved by experiments to not only have no effect on the vegetation on both sides of the road, but to improve the soil. For the common salt snow melting agent on the market, the environmentally friendly snow melting agent will undoubtedly be a new product to replace the traditional snow removing agent in the case of severe corrosion and pollution damage caused by the snow and ice.
6. This product has the effect of dust removal and road surface slip resistance.
Instructions:
It can be artificially sprinkled or mechanically spread. When throwing snow-dissolving agent, it can be determined according to the temperature. Generally, it can be sprayed with snow-dissolving agent at the beginning of snowing, or it can be estimated to be spread 1-2 hours before the road surface freezes. Become ice, can be sprinkled once. The number of spreads during snow removal can be the same as the number of snow removals, and the amount of snow spray applied is referred to the following table.

Note: The snow melting agent has strong hygroscopicity, and the storage environment should be dry and ventilated to prevent exposure and rain. Before and after use, it should be sealed and stored to prevent moisture absorption.
Functions:
Snow melting agent, its role is to melt snow and ice, instead of salt, mainly as urban snow, ice, snow, ice, ice, snow, ice, ice, snow Admixtures, etc.
Snow melting agent is used for snow removal, ice reduction and dust removal in various types of urban roads, highways, highways, railways, overpasses, plazas, bridges, houses and golf courses.
Advantages: The snow removal effect is obvious, and it can exert the performance of continuous and effective snow melting and ice making in low temperature weather. It has good environmental protection performance, can reduce the corrosion of bridges and highways, and has less impact on farmland and plants. It is non-toxic to humans and animals. Pleasant odor, contact with skin, wash with water.
