Caustic Caustic 99 Cangxian

Trona Trona harsh method first crush, dissolve, clarify, and then added to the supernatant lime causticization reaction; after clarification of the resultant supernatant liquid caustic evaporation through a filter to remove impurities salt; and the filtrate was evaporated by the second , then filtered desalination; last filtrate brewed into caustic soda. NaHO3 + Ca (OH) 2 → NaOH + H2O + CaCO3 ↓ 2 soda caustic soda dissolved in water first method, mixed with milk of lime causticization reaction. Caustic fluid clarification, the supernatant is concentrated by evaporation to a concentration of liquid products, the concentrate was further boiled down to obtain a solid product. Here to tell you about some buyers often worry about the problem, which is common sense caustic color: some buyers into the product and occasionally encounter some form conditions: if the color is slightly red, blue, yellow. These circumstances would affect the content of caustic soda for you, I think this is the buyers of the most concern. Caustic color: color caustic soda national standards requirements: Appearance: white glossy, allowing microstrip color, most of caustic soda factory, some white and shiny, the most beautiful, most happy customers also appear, such Caustic is necessary from clarity, thickness about the content of the measure. Caustic soda as a little pinkish, which is a normal phenomenon, but the base of ferric oxide in a little more impact on the caustic soda is not great. Caustic if a little gray hair, stressed that "a little", buyers do not panic, it may be with caustic soda brewed pot a little unclean concerned, will not affect too much. 5, the electrolysis of salt water to produce chlorine, hydrogen and liquid sodium hydroxide. Chlorine and ethylene response is polyvinyl chloride, PVC production materials, hydrogen as an energy source to continue recycling. Liquid sodium is processed into a solid part, the so-called caustic soda, some directly, is caustic. 6, I plant caustic soda production process: the membrane production process. This production process is refined by advanced production technology, it changes the physical properties of caustic soda, sodium hydroxide improved purity, shortening and other raw materials, reaction time, replacing the diaphragm past backward production technology.
