_ Rui Desheng Chemical Sodium Sulfate Sodium Sulfate _ Haihua provided by 瑞德胜 chemical manufacturers. Sodium Sulfate, Rui Desheng chemical, sodium sulphate is Weifang Haihua Rui Desheng Chemical Co., Ltd. (www.ruidesheng.com) 2014 upgrade been newly launched Sodium Sulfate Sodium Sulfate for concrete action not when fertilizers. It is the chemical products. Chemical Name anhydrous sodium products English name Sodium sulfate; Sodium sulfate, anhydrous; Thenardite Synonyms Sodium Sulfate; thenardite formula Na2SO4 Tel: 15263640888 Rui Desheng Chemical Co., Ltd. Weifang Sodium Sulfate editing method of preparation of a (Beach Field Act) use of natural temperature variations in different seasons of the raw material liquid evaporation of sodium sulfate, the crude Glauber crystallized. Summer saltwater containing sodium chloride, sodium sulfate, magnesium sulfate, magnesium chloride and other ingredients poured salt field, evaporated by the sun, winter precipitation crude Glauber. This method is the main method of thenardite made from natural resources, the process is simple, low energy consumption, but poor working conditions, Shandong Sodium Sulfate suppliers, products easily mixed with sediment and other impurities. Method 2 (mechanical freezing) using mechanical equipment heating the raw material liquid was evaporated to -5 ~ -10 ℃ frozen precipitation when thenardite. Compared with the salt field method, this method is not affected by seasonal and natural conditions. Products of good quality Sodium Sulfate Haihua, but high energy consumption. Method three (Salt Lake utilization method) is mainly used for sulfate containing a variety of components - carbonate salt water. In a variety of useful components from the extract, separating the crude mirabilite. Salt water processing including for example sodium carbonate, sodium sulfate, sodium chloride, boride and potassium, bromine, lithium, can be carbonized sodium sulphate salt lake brine Haihua manufacturers to make sodium bicarbonate crystallized into; cooling The mother liquor to 5 ~ 15 ℃, borax crystallized; borax secondary mother liquor after the cryogenic separation to 0 ~ 5 ℃, Glauber's salt precipitate.
