Anti-icing reagents are substances with specific properties that prevent icing of the roadway and the occurrence of emergency situations.
All reagents can be conventionally divided into three categories:
- natural solids :
Includes mixtures of sand and salt in varying proportions. 90% of sand and 10% of salt, is recognized as not environmentally friendly and is not used in cities, as it pollutes "green" areas, spoils shoes and ceramic coatings, but, nevertheless, is recognized as one of the most functional, it is used on highways and federal highways. Salt - due to the specific reaction of sodium chloride when interacting with solid water - ice, a thick salt solution is formed. Its use is fraught with the fact that the oversaturation of roads with salt forms white stains on cars and destroys the rubber tires.
- liquid reagents include a large list of names and characteristics :
Among liquid reagents, the most common is "Antisneg-2" by its chemical composition, it is similar to a salt reinforced with a hydroxide residue, which makes it 6 times more effective than ordinary salt. When placed in a smaller area, anti-snow interacts with more snow than NaCL in the same placement.
- chemical deicing agents :
Deicing agents are very effective, they turn years and snow ice into a solution that is not harmful to cars and removes emergency conditions on the roads. Non-toxic and safe. They have a significant drawback - a very short period of action of several hours, therefore, use is more expensive. The names "GreenRide", "RockMelt Solt", "RockMelt MIX" and others.
