Application
Detergent
Sodium trimer is a detergent additive with excellent performance, and it is also the most dosage in the production process of detergent. It has four aspects: 1. The chelating effect on heavy metal ions: in the water during the washing process, in the water Heavy metal ions can be combined with detergent molecules into insoluble metal salts to reduce the washing capacity and even completely lose effect. Therefore, adding heavy metal ions contained in the water into a chelated chelator must be added to the detergent. Sodium trimer phosphate has a strong chelating effect on heavy metal ions, which can close them and eliminate their adverse effects on washing. In addition, it can capture the various metal components contained in the dirt, and during the washing process, it can solve the dirt away. It can be used as a soap efficiency agent and prevents soap oil from precipitating and frosting.
2. The role of dispel, emulsification, and decentralization of dirt: Dirt often contain human secretions (mainly protein Chemicalbook and fatty substances), and also contain sand soil and dust from the outside. Sodium trimer phosphate has the effect of expanding and soluble protein in the dirt, thereby solving the effect of relieving gel; it can promote emulsification on fat; it has a strong effect on lubricating oil and fat. In adjust the pH value of the buffer soap.
3. It has the effect of preventing blocks: powder synthetic detergent has hygroscopicity. If it is stored in a place with large humidity, the phenomenon of block must be occurred. It is extremely inconvenient to use the detergent of the block. The six aquatic compounds formed after absorbing sodium trimer phosphate have dry characteristics. When the detergent formula is used in large quantities, it can prevent the phenomenon of blocks caused by moisture absorption, and maintain the dry granular shape of the synthetic detergent.
4. It has a large alkaline buffer effect and keeps the pH value of the washing solution around 9.4, which is conducive to the removal of acid dirt.


Food industry application
Water holding agent, quality improvement agent, pH regulator, metal chelating agent. my country's "Sanitary Standards for Food Additives" (GB2760-2011) stipulates that canned, fruit juice (fruity) drinks, plant protein drinks, the maximum usage is 1.0g/kg; Instant noodles, the maximum usage is 5.0g/kg. When using composite phosphate, canned meat products must not exceed 1.0g/kg of phosphate meter; refining milk must not exceed 0.50g/kg; when used with sodium phosphate and sodium phosphate, this product shall not exceed 5g// KG; Western-style cooking, smoked ham is executed according to GB13101-1991 "Western-style cooking, smoky ham hygiene standards", and must not exceed 5g/Chemicalbookkg during composite (Western-style ham can be appropriately added to 8g/kg. Other use. Other use. Other use. Reference: For cans of ham, under appropriate conditions, it is conducive to the improvement of product quality, such as complete products, good color, tender meat, easy slicing, and gloss of sodium trimer. L00KG meat plus 3 mixed salt 2.2kg, sodium trimer phosphate 85g, fully stir well, marinate 48 ~ 72h in the cold storage 0 ~ 4 ºC, the effect is good . It is used in canned broad beans to soften the bean skin. This reduces the toughness of the skin.
