(www.ruidesheng.com) 2013 upgrade been newly launched development of new deicing salt to reduce environmental pollution researchers in the laboratory of metal deicing corrosion experiments. Recently snowmelt salt, Weifang Rui Desheng Chemical Co., Ltd. R & D to meet the new deicing roads, bridges and key sensitive areas and to a large extent reduce the use of environmental pollution of the new Weifang Rui Desheng Chemical Co., Ltd. Tel: 5330114 Fax: 5300069 chloride deicing salts snowmelt principle is: chloride deicing salts dissolved in water (snow), the freezing point of the solution drop below freezing. After the sodium chloride are dissolved in water as the freezing point -10 ℃, calcium chloride at about -20 ℃, acetic acid salts of up to about -30 ℃. Salt dissolved salts makes lower the freezing point of the snow melting snow salt damage, so it is difficult to dissolve the salt and then after the formation of ice in the snow. The reason is that the plant snow salt was dissolved in water deicing ion concentration in water increases, the water vapor pressure of the liquid drop, but the vapor pressure of the solid ice unchanged. When ice-water mixture to achieve solid-liquid phase coexistence equilibrium vapor pressure of equal status, the ice will melt. In addition it can be sprinkled with snow deicing.
