Classification of chemical snow melting agents

1. Inorganic snow melting agents with chlorine salt as the main component are called chlorine salt type snow melting agents. This type of snow melting agent contains sodium chloride, calcium chloride, magnesium chloride, potassium chloride, etc., commonly known as "ice melting salt". The proportion of the aforementioned ingredients can be adjusted according to different regions and different snow conditions. There are sodium chloride:magnesium chloride 7:3, sodium chloride:calcium chloride 8:2, sodium chloride:magnesium chloride:calcium chloride 7:2:1, etc., but the main ingredient is still industrial Salt (N aC 1). The advantage is that it is cheap

2. Organic snow melting agents with potassium acetate as the main component are called non-chlorine-containing snow melting agents. Such snow melting agents include organic and inorganic salts, amines, alcohols, etc. This type of snow melting agent is expensive, and is roughly 10 times more expensive than inorganic chlorine-containing snow melting agents. Mainly used in airports, railways and other important occasions.

3. A mixed snow melting agent formed by combining chlorine salt type and non-chlorine salt type snow melting agent, and adding a small amount of corrosion inhibitor is called chlorine salt environmentally friendly type. For example, the ingredients of a factory's chlorine salt environmentally friendly snow melting agent are high-temperature salt 40%, calcium chloride 30%, urea 15%, sodium acetate 13.5%, and corrosion inhibitor 1.5%. This type of snow melting agent can not only reduce salt damage caused by pure chlorine salts, reduce corrosion, but also significantly reduce the cost compared to organic snow melting agents.

What's the advantage of calcium chloride desiccant bag?

First :Moisture absorption performance advantage: the moisture absorption capacity of calcium chloride desiccant is more than 10 times that of ordinary desiccants. In the case of the same moisture absorption, calcium chloride desiccant is cheaper than silica gel desiccant.

Second: Packaging advantages: common desiccants generally use single-layer packaging that cannot lock water, and calcium chloride desiccants use double-layer packaging of DuPont paper + non-woven fabric with strong water-locking ability.

Third: Advantages of applicable temperature range: When the temperature exceeds 37℃, silica gel desiccant will not only no longer absorb water but will release water vapor (this feature determines that silica gel desiccant is not suitable for shipping), while calcium chloride desiccant is suitable for -5 ℃ to 90℃.
