Auto snow brush test principle



Aluminum and replacement from mercury nitrate of mercury in formation of primary
batteries, to speed up the aluminum snow brush loss rate of electrons, mercury dissolved aluminum forms aluminum amalgam and hinder the generation of protective alumina layer, so that the auto snow brush for cars by oxygen oxidation alumina.
Aluminum is a kind of active metal, surface contact air easily alumina layer oxidized by snow brush oxygen in air to form a layer of compact thin. Protect the internal metal aluminum will not continue to be oxidation; snow brush for cars test, in the aluminum coated on the surface of mercury nitrate solution, mercuric nitrate through the protective layer, substitution reaction with aluminum, generation of liquid metal mercury. Mercury at room temperature automotive snow brush can be generated and combined with aluminum alloy aluminum amalgam, the name is called "aluminum amalgam in commonly, generating surface of aluminum aluminum amalgam, protective effect of aluminum lost alumina protective film, soon to be oxidized by oxygen in air into a solid white alumina, aluminum amalgam surface of aluminum as a result of oxidation and reduction, the aluminum foil aluminum snow brush with ice scraper will continue to dissolve into the aluminum amalgam, and continue to be oxidized into white alumina on the surface, so that the white alumina in aluminum surface accumulate.

The introduction of snow brush

Snow vehicles for auto snow brush take PP + spring steel wire or galvanized steel wire material combination, depending on the emergency situation and pavement material selection, selection of ice more full galvanized steel wire, loose snow, more choice of whole PP yarn, but the use of the most PP PA wire is galvanized steel wire with a ratio of 1: 1 mix doping, because the whole PP yarn is not enough, the whole operation is wrong with galvanized steel wire will break the two complement each other, the size can be divided into internal and external 900 with 300, Nene outside 800 with 255, 660 with 205 outside, the outer 550 with 168, with 128 in the outer 450, also according to customer requirements. snow brush with ice scraper it with wear, no damage to the road and the snow is good, can not break the eternal snow between ultra-low temperature climatic conditions, such as interest and good elasticity, effectively cover the urban environment and sanitation to meet the needs of municipal and efficient snow removal.
