  三聚磷酸钠的工业用途
  用作洗涤品助剂,亦可用于石油、冶金、采矿、造纸、水处理等。主要用作合成洗涤剂的助剂,用于肥皂增效剂和防止条皂油脂析出和起霜。对润滑油和脂肪有强烈的乳化作用,可用于调节缓冲皂液的PH值。工业用水的软水剂。制革---剂。染色助剂。油漆、高岭土、氧化镁、碳酸钙等工业中配制悬浮时作分散剂。钻井泥浆分散剂。造纸工业用作防油污剂。食品工业中用于罐头,果汁饮料,奶制品,豆乳等的品质改良剂,水分保持剂。主要供火腿罐头嫩化,蚕豆罐头中使豆皮软化,亦可用作软化剂和增稠剂。STPP还存在其不可避免的环境危害,由于本身含磷,容易造成水体富营养化。由于国家的限磷政策的出台,三聚磷酸钠在洗涤剂助剂方面的应用逐渐减少,逐步被层状硅酸钠、分子筛等产品代替。
  Used as a washing agent, can also be used in petroleum, metallurgy, mining, paper, water treatment. It is mainly used as an auxiliary agent for synthetic detergents, as a synergistic agent for soap and to prevent the grease from precipitation and frosting. It has strong emulsifying effect on lubricating oil and fat, and can be used to adjust the PH value of buffer soap. A water softener for industrial use. Tanning -- agent. Dyeing AIDS. Paint, kaolin, magnesium oxide, calcium carbonate and other industrial preparation of suspension dispersant. Drilling mud dispersant. The papermaking industry is used as an oil repellent. In the food industry used for canned, fruit juice drinks, dairy products, soy milk quality improver, water retention agent. It is mainly used for tenderizing ham and softening bean skins in canned broad beans, and it can also be used as a softener and thickener. STPP also has its inevitable environmental harm, because it contains phosphorus, it is easy to cause water eutrophication. Due to the introduction of the national phosphorus limit policy, the application of sodium tripolyphosphate in detergent additives is gradually reduced, and gradually replaced by layered sodium silicate, molecular sieves and other products.
三聚磷酸钠
  食品行业的用途:水分保持剂、品质改良剂、pH调节剂、金属螯合剂。我国《食品添加剂使用卫生标准》(GB2760-2011)规定:罐头、果汁(果味型)饮料、植物蛋白饮料,更大使用量为1.0g/kg;乳制品、禽肉制品、肉制品、冰淇淋、方便面,更大使用量为5.0g/kg。复合磷酸盐使用时,以磷酸盐计,罐头肉制品不得超过1.0g/kg;炼乳不得超过0.50g/kg;本品与焦磷酸钠、磷酸钠复合使用时,以磷酸盐计不得超过5g/kg;西式蒸煮,烟熏火腿按GB13101-1991《西式蒸煮,烟熏火腿卫生标准》执行,复合使用时不得超过5g/kg(西式火腿可适当多加,以磷酸盐计为8g/kg。其他使用参考:用于火腿罐头,在适当条件下有利于产品质量的提高,如成品形态完整、色泽好、肉质柔嫩、容易切片、切面有光泽。三聚磷酸钠用于火腿原料肉的腌制,每l00kg肉加3号混合盐(精盐91.65%、砂糖8%、亚硝酸钠0.35%)2.2kg、三聚磷酸钠85g,充分搅拌均匀,在0~4℃冷库中腌制48~72h,效果良好。用于蚕豆罐头生产,可使豆皮软化。许多果蔬有坚韧的外皮,随着果蔬的成熟,外皮愈加坚韧。在果蔬加工热烫或浸泡用水中,加入聚磷酸盐,可络合钙,从而降低外皮的坚韧度。
  Food industry USES: water retention agent, quality improver, pH regulator, metal chelating agent. China's "hygienic standards for the use of food additives" (gb2760-2011) provisions: canned, fruit juice (fruit-flavored) drinks, vegetable protein drinks, the maximum use of 1.0g/kg; Dairy products, poultry products, meat products, ice cream, instant noodles, the maximum use of 5.0g/kg. When using complex phosphates, canned meat products shall not exceed 1.0g/kg in terms of phosphates; Condensed milk shall not exceed 0.50g/kg; When used in combination with sodium pyrophosphate and sodium phosphate, the amount of phosphate shall not exceed 5g/kg. Western cooking, smoked ham according to gb13101-1991 "western cooking, smoked ham hygiene standards" implementation, composite use should not exceed 5g/kg(western ham can be appropriately added, in phosphate is 8g/kg. Other references: used for canned ham, under the appropriate conditions to improve the quality of products, such as finished form integrity, good color, tender meat, easy to slice, cut surface luster. Sodium tripolyphosphate is used for curing ham raw meat. For each l00kg of meat, add no.3 mixed salt (refined salt 91.65%, granulated sugar 8%, sodium nitrite 0.35%). Used in the production of canned broad beans to soften the skin. Many fruits and vegetables have tough skins that get tougher as they mature. In the hot processing of fruits and vegetables or soaking water, add polyphosphate, can complexate calcium, thereby reducing the hardness of the skin
