Tel 0536 -5330114 de-icing agent, is a chemical, its composition is mainly acetic acid and potassium chloride, and both are classified. Deicing function is to melt the snow on the road, easy way to clear, deicing agents of ice kinds of domestic and foreign agents are generally used in two categories: one is based on potassium acetate as the main component of organic deicing salt, such snowmelt agent snowmelt effect, basically no corrosion damage, but its price is too high, generally used for airports and other important places. Another is the "chloride" as the main component is an inorganic deicing salt such as sodium chloride, calcium chloride, magnesium chloride, potassium chloride, generally referred to as 'deicing salt.' The advantage is cheap, organic deicing equivalent to only 1/10, but the erosion of its large public infrastructure is very serious. The most common deicing salt are in this category, the most used is sodium chloride (ie salt). Snowmelt principle deicers principle "chlorine salts" deicing is: "chlorine salts" deicing salt dissolved in water (snow), its freezing point at zero, such as sodium chloride (table salt main ingredient) dissolved in water After freezing at -10 ℃, calcium chloride at about -20 ℃, acetic acid up to about -30 ℃. Dissolved salts other than the need for an endothermic, so that there is an effect to reduce the freezing point of brine, and therefore it is difficult to dissolve the salt and then after the ice formed in the snow. Moreover, the deicing salt is dissolved in water, the water concentration increased, so that the water vapor pressure of the liquid drop, but the vapor pressure of the solid ice unchanged. To achieve a solid-liquid mixture of ice water vapor pressure of the state of the ice has melted. This principle can also be a good explanation of the brine freezing the truth is not easy. We know that the water is a special material, i.e., the smaller the density of ice (solid state density greater than the density of the liquid under normal matter), and therefore the greater the pressure, the lower the melting point of ice. Often see, where snow is often easy to melt the wheels run over is the truth. After deicing salt sprinkled on the snow surface, and then rolling the vehicle to make it easier to melt the snow.
