Rui Desheng Chemicals | deicing [manufacturers] | provided by 瑞德胜 deicing chemicals. We are Weifang Rui Desheng Chemical Co., Ltd. (www.ruidesheng.com) located at: Shandong Weifang specializes in: sodium sulfate, sodium metabisulfite, deicing salt, calcium chloride, baking soda, deicing chemical composition and standards: MgCl2 · 6H2O: 62% (± 2%) NaCl: 38% (± 2%) complex -2: on the basis of the above criteria is added 1-1.5% of HMK rust inhibitor. Particle size: 3 ± 1mm ??technical characteristics: This product raw salt, magnesium sophisticated use of magnesium chloride coagulation point high in the air principle, the use of new technology and equipment, with its unique way of refined granulated deicing salt manufacturers, is a new antifreeze snowmelt products. Snowmelt 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 freezing at - 10 ℃ Shandong Haihua deicing salt, calcium chloride at about -20 ℃ deicing salt, 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.
