磷酸三鈉的用途有鍋爐軟水劑，用于鞣革、織物的增重劑木材和紙張的阻燃劑，釉物和焊藥。染色用媒染劑，在印染工業(yè)中用作雙氧水漂白的穩(wěn)定劑。是制造磷酸鈉和其它磷酸鹽的原料。

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.

之所以能作為硬水軟化劑，磷酸三鈉作鍋爐用水爐內(nèi)處理劑是因?yàn)槭裁茨?？下?a href="http://m.jsyjs.net">氫氧化鉀廠家為你講解：

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.磷酸三鈉能與水中容易結(jié)成鍋垢的可溶性鈣鹽、鎂鹽等起作用，生成不溶性的磷酸鈣Ca3(PO4)2、磷酸鎂Mg3(PO4)2等沉淀物懸浮於水中，所以使鍋爐不結(jié)鍋垢。

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.同時(shí)多余的磷酸三鈉，還能將已結(jié)的鍋垢部分變成松軟而脫落。因此節(jié)約了鍋爐的用煤，維護(hù)了鍋爐的和延長(zhǎng)了鍋爐的使用期限。反應(yīng)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)↓
