1. Applications for quality improver, have to improve food complexing metal ions, pH, ionic strength increasing action, thereby knot efforts to improve food and water holding capacity. Chinese regulations can be used for cheese, the maximum use of 5g / kg; in Western-style ham, meat, fish, shrimp and crab in the maximum usage is 3.0g / kg; the largest in the canned food, juices, beverages and dairy products is 0.5g / kg. 2, as a water softener and detergent in chemical, textile, printing and dyeing, paper, power generation and other industries, pH buffering boiler scale inhibitor, paper dyeing water softener sodium sulphate, producing glossy paper with adhesive fixing agent when dyeing, silk fabric enhancer-line anti-crispy agent. Metallurgical industry for chemical degreasing, decontamination sodium sulfate role for photographic developing solution excellent accelerator. Bottle tooth cleaners and detergents. Rubber latex coagulant. Juice purification agents. Phosphate plays the role of quality improvement in food processing, for example, keep the meat water holding capacity, enhance the role of adhesive force sulfuric acid trisodium use to reduce the loss of nutrients in meat and save the meat tenderness in meat products. In food processing is also used as an emulsifier, nutritional supplements, quality improver. It is the preparation of the surface of edible alkaline material, also used in the manufacture of refined sugar and α- starch. Also used as a food bottles, cans and other detergents. 3, solid trisodium phosphate (TSP) belong to a strong base weak acid salt, a strong alkaline and high solubility, chemical stability, long-term preservation, the containment spray system (EAS) is added to water spray TSP substitute NaOH, capable of adjusting the pH of the spray solution, effectively removing the release of cooling water from leaking to the containment of the iodine gas, alkali avoid injury to staff, easy to clean up after the accident. First aid measures Skin contact: Remove contaminated clothing immediately and thoroughly washed at least 15 minutes with plenty of water. Medical treatment. Eye contact: immediately open the upper eyelid, at least 15 minutes with running water or saline. Medical treatment. Inhalation: rapidly from the scene to fresh air. Keep the airway open. Give oxygen breathing difficulties. Stop breathing sulfuric acid trisodium storage, artificial respiration immediately. Medical treatment. Fresh into: coverage immediately mouthwash, or egg white to the blues. Medical treatment. Fire Fighting Measures Suitable extinguishing media: non-combustible. Available around the fire extinguishing media. Wearing masks and gloves. Use sand, dry lime or soda ash mixture, then buried deep in special waste sites. If large spills, recycling or waste processed sound. Sodium sulfate, storage, Zhengzhou Ronda chemicals, sulfuric acid trisodium Nansanhuan provided by Zhengzhou Longda Chemical Products Limited.
