In winter, the road will often occur icing phenomenon, so it is often necessary to use snow melting agent to deal with, and the early snow melting agent is represented by calcium chloride, but with the development of society, calcium chloride snow melting also exposed some shortcomings, people have begun to look for alternatives, such as magnesium chloride. But the performance effect of magnesium chloride is really better than calcium chloride?
Magnesium chloride, it has good water absorption performance, no non-flow after absorbing moisture, but the disadvantage is low yield. Widely used as high absorbent desiccant. Moisture absorption speed: it varies according to the packaging material. Under the same kind of packaging material, the moisture absorption speed is several 10 times of ordinary desiccant.
Calcium chloride has the effect of adsorption static moisture reduction and odor removal. Calcium chloride not only has fast adsorption speed and high adsorption capacity (up to 300% of its own weight), but also is non-toxic, tasteless, non-contact corrosive, non-environmental pollution, especially non-damaging to human body, and is widely used in oil seal, optical medical and health food products. Therefore, calcium chloride can be used as the raw material of desiccant and is one of the raw materials of desiccant. It is also a raw material of desiccant with high moisture absorption rate, and its moisture absorption rate can reach about 300% of its own weight. But the salt in calcium chloride may cause damage to the road and the surrounding vegetation, and even enter the ground through the road, causing groundwater pollution.
Therefore, calcium chloride and magnesium chloride are unable to achieve the perfect snow melting and drying effect, while the environmental damage problem is still occurring, looking for new dry snow melting agent is imminent!
