Main Uses Of Sodium Tripolyphosphate
May 28, 2021
Sodium tripolyphosphate - main use industrial production
It can also be used in crude oil, metallurgical industry, mining, paper industry, sewage treatment, etc. It can be used as modifier of metal cutting fluid, synergist of soap and preventing vegetable oil from precipitation and frosting. It has obvious chemical action on lubricating grease and human body fat, and can be used to adjust pH value of buffer soap. Industrial water softener. Tanneries --- leather chemicals. Color modifier. In the industrial production of paint, porcelain clay, magnesia and calcium bicarbonate, it is used as thickener when floating. Drilling fluid thickener. It is used as anti oil stain agent in paper industry. In food industry, it is used as bread improver and water maintainer for canned food, pulp beverage, dairy products, soybean milk, etc. Canned cowpea can soften soybean oil skin. It can also be used as softener and tackifier.
STPP also has its unavoidable environmental pollution, because of its own phosphorus content, it is very easy to lead to water eutrophication.
Due to the promulgation of the current phosphorus limitation policy in China, the application of sodium tripolyphosphate in detergent modifier is gradually reduced, and is gradually replaced by laminated sodium metasilicate, carbon molecular sieve and other commodities.
Food enterprises
Water maintenance agent, quality bread improver, pH conditioner, metal material antioxidant. In China, the hygienic standard for the use of food additives (gb2760-2011) requires: canned food, fruit juice (orange flavor) drinks, green plant protein drinks, the larger demand is 1.0g/kg; Dairy products, poultry products, meat products, ice cream, instant noodles, the larger demand is 5.0g/kg. In the application of compound phosphate, the content of polyphosphate in canned meat should not exceed 1.0g/kg; 40 g / kg for condensed milk; When this product is combined with sodium pyrophosphate and betamethasone, it should not exceed 5g / kg in polyphosphate; European style steaming, smoked ham according to GB 13101-1991 "western style cooking, smoked ham health standard" implementation, compound application should not exceed 5g / kg (European sausage can be moderately increased, calculated by polyphosphate as 8g / kg). Other application references: for canned sausage, it is beneficial to improve the quality of products under appropriate standards, such as detailed shape, good color, tender meat, very easy to slice, glossy cross section. Sodium tripolyphosphate was used to marinate raw material meat of sausage. Each l05kg meat was added with 2.2kg of No.3 mixed salt (table salt 91.65%, white granulated sugar 8%, sodium nitrite 0.35%) and 85g of sodium tripolyphosphate. It was well stirred and marinated at 0 ~ 4 ℃ for 48 ~ 72h. It can be used in the production of cowpea can to soften the soybean oil skin. Many fruits and vegetables have a firm skin. With the improvement of fruits and vegetables, the skin is more firm. Adding polyphosphate to the water for blanching or soaking in the production and processing of vegetables and fruits can reduce the toughness of the epidermis
Main commercial uses of sodium formate
Today, I'd like to talk with you about the main uses of sodium formate.
1. It is mainly used in the production of benzoic acid, hydrochloric acid, sodium hydrosulfite, disinfectant and cleaning water.
2. Used as experimental reagent, disinfectant and mordant for the measurement of phosphorus and arsenic.
3. Additives. It has the effect of favorable urination. European economy is permitted in China, but not in the United States.
4. It is a chemical intermediate for the production of benzoic acid and hydrochloric acid, and also used in the production of dimethylformamide. It can also be used in pharmaceutical industry, printing and dyeing factory, or coagulant with excessive heavy metal.
5. Used for acrylic resin building coating, tackifier, the most powerful explosive, acid resistant raw materials, airline grease, adhesive additives.
6. The coagulant with excessive heavy metals can produce complex ions of trivalent metal materials in aqueous solution. It is an experimental reagent for measuring phosphorus and arsenic. It is also used as disinfectant, astringent and mordant. Sodium formate is a kind of chemical intermediate for benzoic acid and hydrochloric acid because of its harmfulness. It is usually purchased by ourselves. It is used to produce dimethylformamide and so on.
7. It is used as electrolyte for nickel cobalt alloy lithium batteries.
