磷酸三钠的用途有锅炉软水剂，用于鞣革、织物的增重剂木材和纸张的阻燃剂，釉物和焊药。染色用媒染剂，在印染工业中用作双氧水漂白的稳定剂。是制造磷酸钠和其它磷酸盐的原料。

The uses of trisodium phosphate include boiler water softener, weight increaser for tanning and fabrics, flame retardant for wood and paper, glaze and welding flux. The mordant for dyeing is used as a stabilizer for hydrogen peroxide bleaching in the printing and dyeing industry. It is the raw material for producing sodium phosphate and other phosphates.

之所以能作为硬水软化剂，磷酸三钠作锅炉用水炉内处理剂是因为什么呢？下面氢氧化钾厂家为你讲解：

Why can trisodium phosphate be used as a hard water softener and boiler water treatment agent? The following potassium hydroxide manufacturer will explain to you:

1.磷酸三钠能与水中容易结成锅垢的可溶性钙盐、镁盐等起作用，生成不溶性的磷酸钙Ca3(PO4)2、磷酸镁Mg3(PO4)2等沉淀物悬浮於水中，所以使锅炉不结锅垢。

1. Trisodium phosphate can react with soluble calcium salt and magnesium salt which are easy to form scale in water, and generate insoluble calcium phosphate Ca3 (PO4) 2, magnesium phosphate Mg3 (PO4) 2 and other precipitates suspended in water, so that the boiler will not form scale.

2.同时多余的磷酸三钠，还能将已结的锅垢部分变成松软而脱落。因此节约了锅炉的用煤，维护了锅炉的和延长了锅炉的使用期限。反应式如下：

2. At the same time, the excess trisodium phosphate can also make the scaling part of the boiler become soft and fall off. Therefore, the coal consumption of the boiler is saved, the safety of the boiler is maintained and the service life of the boiler is extended. The reaction formula is as follows:

3CaSO4＋2Na3PO4→3Na2SO4＋Ca3(PO4)2↓

3CaSO4＋2Na3PO4→3Na2SO4＋Ca3(PO4)2↓

3MgSO4＋2Na3PO4→3Na2SO4＋Mg3(PO4)↓

3MgSO4＋2Na3PO4→3Na2SO4＋Mg3(PO4)↓
