Granular anti-ice reagent: features and propertiesJanuary 27, 2018
The most common means of dealing with ice during the winter cold are anti-icing agents, which differ from each other not only in chemical composition or type of origin, but also in the form of release. Recently, granulated reagents that have increased efficiency are in the greatest demand..
In order for the fight against ice to be as effective as possible in all weather conditions, it is required to choose the right anti-icing reagents for road treatment. Currently, the most popular and common anti-ice agents are calcium chloride, technical salt, marble and granite chips, and magnesium chloride.
According to their structure and release form, all reagents used are divided into several types:
- Powder.This is the most well-known and common form of release of anti-icing agents, which is a granular substance. Most commonly, reagents such as sodium chloride and calcium chloride are available in powder form. The main advantage of this form of release of a substance is its ease of storage.
- Liquid. This is a relatively new form of release of anti-icing agents, which is most often used for clearing areas of snow in small enterprises and in private yards. The lack of liquid reagents consists in their relatively high cost in comparison with substances of other forms of release.
- Granulated. This form of release of reagents is a solid small granules, which, in addition to anti-icing properties, also have abrasive properties, preventing sliding on the icy road. Recently, it is granulated reagents that are in high demand, since their cost is comparable to powder means, and their efficiency and speed are several times higher.
The main advantage of granulated anti-icing agents is their optimal shape, which is round grains of small size.Thanks to this structure, the granules, barely falling on the icy surface, instantly come into contact with ice, biting into it during use. The result of this impact is not only the rapid melting of ice, but also its splitting, which reduces the adhesion of the ice crust to the road surface. Thus, after using the reagents in the granules, the remaining ice is easily removed from the asphalt with the help of available tools or special equipment.
Additional properties of granular reagents
In addition to all the above advantages of the anti-icing agent in granules, granulated calcium chloride or magnesium chloride has also such advantages as:
- Environmental cleanliness and safety of operation. Unlike technical salt, which in the process of use causes irreparable damage to pavements and other surfaces, granulated reagents do not cause any harm to the environment.
- Resistance to frost. Due to the special structure, the anti-icing agent granules are capable of effectively performing their work even at low air temperatures down to -30 ° C.
Due to affordable cost, safety and high efficiency, calcium chloride in the granules actively replaces the technical salt and sand-salt mixture in many localities.
