The function of snow melting agent is to melt the snow on the road. The speed of snow melting is fast, the dosage is small, and it is easy to dredge the road. What are the methods of using snow melting agent?
1. Spread out
People or machines directly sprinkle deicing agent on the snow. The reference amount of spraying is 30-50g / m² when the snowfall is less than 50mm, and the amount or times of spraying should be increased when the snowfall is more than 50mm or the temperature is too low.
2. Spray liquid
The deicing agent was mixed into an aqueous solution with a reference concentration of 20% and sprayed on the snow. When the snowfall is below 50 mm, the reference spraying amount is 0.4 L / m². When the snowfall is above 50mm or the temperature is too low, the concentration or spraying times should be increased appropriately. It is a good way to prevent snow from freezing on the ground after falling.

Recent soda Market - may After the continuous increase of soda price in April, the trend of soda has finally stabilized in the near future. The overall production of soda in China has maintained more than 80% and the supply of goods is sufficient. The enthusiasm of shipping has been improved, and the demand of end customers has not changed much. Most end users purchase on demand, and traders are flexible to receive orders for shipment. The follow-up of new orders is not as good as that in the early stage. Some operators have the intention to stabilize the price, so it is difficult to make big changes in the domestic soda spot market in the short term.

Function of calcium chloride desiccant
Desiccant, as the name suggests, is used for drying and moisture-proof. For example, the desiccant in the food bag absorbs the moisture in the bag, so that the food will not be affected by moisture and deterioration, and keep the fresh and crisp taste. In the wardrobe, the desiccant can be prevented, even in the rainy season, the clothes will not be affected by moisture and mildew. In the garage, the desiccant can prevent the car parts from moisture even if the car is not used for a long time, Desiccant is widely used, in fact, it can be used in many living and production environments.
Application method of solid environmental protection snow melting agent
Application method of solid environmental protection snow melting agent Snow melting agent When it snows in winter, we often use snow melting agent, which is mainly used for snow and ice removal of urban roads, highways, airports, ports, bridges and other facilities. Some snow melting agents can also be used as quick melting agent and antifreeze admixture for ice and snow melting in winter construction of construction projects. So how is it used? 1. Usage: snow melting agent is sprayed by spraying truck, which is usually solid spraying. When there is no snow melting agent, it can be loaded by truck and scattered manually. 2. Dosage: during solid spraying, it can be determined according to the situation of each region, and the reference parameter is 50-100g / m2. 3. Usage time: the time of spreading snow melting agent is mainly determined according to meteorological conditions (snowfall, wind speed and temperature). Generally, it can be spread at the beginning of snow, or it is estimated that it can be spread 1-2 hours before the road freezes. In case of heavy snow, the spreading amount and times shall be adjusted based on the fact that the ground is not frozen. When the ground is covered with thick ice and snow, appropriate vehicles or tools shall be used to remove the ice and snow before spreading, so as to reduce the use of snow melting agent.
Composition and drying principle of calcium chloride desiccant
Its main raw material is calcium chloride, which can chemically react water molecules with calcium chloride to absorb moisture from the surrounding environment and convert it into gel to achieve adsorption effect. The internal substance of calcium chloride desiccant is powder. If a child tears the package of calcium chloride desiccant, the calcium chloride powder inside is easy to enter the eyes, which will cause symptoms such as eyelid redness and swelling, white burns on cornea and conjunctiva. In mild cases, corneal leukoplakia will be caused after treatment, affecting vision, and in severe cases, blindness will be caused. At the same time, although calcium chloride can be used as food additives, calcium chloride desiccant is not edible. The packaging materials of calcium chloride desiccant are generally fixed. The inner layer is PET film + unidirectional breathable cloth or unidirectional breathable DuPont paper, and the outer layer is unidirectional breathable cloth, which can well prevent the leakage of calcium chloride desiccant. Calcium chloride desiccant becomes water after absorbing moisture. In fact, it is not pure water, but calcium chloride aqueous solution. If nothing else is added, it will flow out. Therefore, calcium chloride desiccant needs to add starch, so calcium chloride desiccant will turn into yellow condensate after moisture absorption.
