There is an old Chinese proverb: “The weather turns cold in July, and winter clothes start to be made in September”. Another winter begins in the middle and high latitude regions of the northern hemisphere, and Harbin in China, Quebec in Canada, Sapporo in Japan, Oslo in Norway and other regions are about to welcome a new ice and snow carnival, and people are full of joy to enjoy a wonderful winter.
However, every coin has two sides. While ice and snow enrich people’s daily life, they also cause serious troubles to transportation and travel. Every winter, the areas north of 45 degrees north latitude will be heavily snowed on the roads, causing serious traffic accidents and transportation stagnation. At this time, the snow melting agent has played a huge role. Once there is severe snowfall, a large number of sanitation workers and traffic police will spread “salt” on the road, and the main purpose of spreading “salt” is to speed up the melting of snow. Assuming that the local air temperature is -5°C, the snow will not melt at this time, because the melting point of ice at 1 standard atmosphere is 0°C. If you want snow to melt, the usual way is to heat it up, but this is too expensive.
If it cannot be heated, another method is to lower the melting point of ice—after adding salt, the melting point of ice drops to -10°C, and the temperature at -5°C is significantly higher than the melting point at this time, so snow can be melted into water.
There are two common deicing agents, organic deicing agent and inorganic deicing agent.
Inorganic deicing
The inorganic deicing used in large areas such as roads and streets. The material of inorganic deicing agent is generally based on chlorine salt, such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride and so on. Therefore, inorganic deicing agents are often referred to as chlorine salt deicing agents, or deicing salts. Because the material of chlorine salt is easy to obtain and the price is relatively cost-effective, it is suitable for places where it is used in large quantities.
Organic deicing
On the other hand Organic snow melting agent, this kind of snow melting agent has good snow melting effect. Recently, HOO CHEMTEC, a company specializing in the production of organic snow melting agent and other chemical products, has brought high-efficiency organic snow melting agent, in order to provide more high-quality snow melting agent products to the majority of purchasing friends choose.
Potassium Acetate
Also known as potassium acetate, is mostly in the form of white fine particles or powder, has a salty taste, is easily deliquescent, easily soluble in water, ethanol and methanol, and insoluble in ether. Mainly used:
1. Production of penicillin potassium salt, buffer and diuretic; reagents for the preparation of absolute ethanol, industrial catalysts, additives and additives;
2. Used in the field of oil drilling and oil extraction;
3. Deicing and snow melting of airport roads and production of vehicle antifreeze.
Sodium Formate
There are two specifications of sodium formate, powder product and liquid product; soluble in water and ethanol, non-toxic and non-corrosive. Mainly used:
1. Leather industry, camouflage acid in chrome tanning process;
2. Reducing agent in printing and dyeing industry; used in the production of hydrosulfite, oxalic acid and formic acid;
3. It can also be used as a drilling aid; it can also be used as a snow melting agent for airport runways.
