Vladivostok liquid reagents do not cope with icing
Spring in Primorye began with a storm warning. Strong winds, blizzards, snow drifts and ice hit the Beijing March 1. And until now, the weather does not improve. As a result, the hilly roads of the city have become icy attraction, life-threatening. Primorye remains only to hope for an early thaw and sun.
Vladivostok road
As on protyazhen6ii all winter, and now, anti-icing agents (CDP) used in Vladivostok, showed their complete ineffectiveness. Liquid calcium chloride solution heats the ice only to -7 degrees. At lower temperatures it solidifies. From this road and what happens is that we see now. On the day in Primorye are 70 automobile accidents. Only on March 19 with injuries in the hospital got five.
Calcium chloride deicing great tool, but only as part of multi-component combination of reagents. By itself, it has a high viscosity, which causes increased slippery roads. This deficiency is compensated in combining reagents. Since the viscosity of multicomponent PGR, which include calcium chloride, sodium, potassium, and may include formates and acetates of potassium, calcium and sodium, significantly lower than separately from calcium chloride.
Corrosion in combined anti-icing materials are sodium or potassium formate. They are also quite well the ice is melting, and the have a very low corrosion activity.
On the ineffectiveness of one component reagents for a long time, scientists say. Again, the idea was announced in March 2013 as part of the hearing, which took place in the Public Chamber of the Russian Federation.
Ph.D. in Chemistry Michael Reinov noted that multi-agents are much safer than either of their constituents.
"This composition of ice-funds to compensate and minimize the harmful actions and enhance the positive qualities," - said Michael Rainey.
"Used anti-icing reagents studied for a long time. The composition of sodium chloride, calcium and potassium, with the addition of formate has minimal impact on people and the environment "- said researcher Laboratory of Hygiene and the soil, the chairman of the Council of young scientists and specialists Marina Vodianova.
Therefore, experts recommend the use in cold areas with hilly terrain such as Vladivostok, solid multi-icing materials.
