DTPMPA在水處理中用作循環冷卻水和鍋爐水的阻垢緩蝕劑，特別適用於鹼性循環冷卻水中作為不調pH的阻垢緩蝕劑，並可用於含碳酸鋇高的油田注水和冷卻水、鍋爐水的阻垢緩蝕劑；在復配藥劑中單獨使用本品，無需投加分散劑，污垢沉積量仍很小。

DTPMPA也可用作過氧化物穩定劑、紡織印染用螯合劑、顏料的分散劑、氧脫木素穩定劑、化肥中微量元素攜帶劑、混凝土添加劑。此外，在造紙、電鍍、金屬酸洗和化妝品等方面也得到了廣泛應用。還可作氧化性殺菌劑的穩定劑。

DTPMPA用塑料桶包裝，每桶30kg或根據用戶需要確定。貯於室內陰涼處，貯存期為十個月。

安全防護

DTPMPA為酸性，應避免與眼睛、皮膚接觸，一旦濺到身上，應立即用大量水沖洗。

Diethylene Triamine Penta (Methylene Phosphonic Acid)

(DTPMPA)

CAS No:15827-60-8 Dequest: 2060

Molecular Formula:C9H28O15N3P5 Molecular weight: 573.2

DTPMPA is innocuous, easy to be dissolved in acid solution. DTPMPA has excellent scale and corrosion inhibition and good thermal tolerance ability. DTPMPA can inhibit the scale formation of carbonate, sulfate and phosphate. On situation of alkali environment and high temperature (above 210℃) DTPMPA has better scale and corrosion inhibition effect than other organophosphines.

DTPMPA can be used as scale and corrosion inhibitor in circulating cool water system and boiler water, and especially in alkali circulating cool water system without additional pH regulation, It can also be used in oilfield refill water, cool water and boiler water with high concentration of barium carbonate. When used alone, little scale sediment is found even none of dispersant is used.

DTPMPA can also be used as peroxide stabilizer, chelating agent in woven & dyeing industry, pigment dispersant, microelement’s carrying agent in fertilizer and concrete modifier. In addition, DTPMPA is used in papermaking, electroplating, acid cleaning and cosmetics.

Normally In 250kg net Plastic Drum, IBC drum can also be used as required. Storage for ten months in room shady and dry place.Safety Protection:

Acidity, Avoid contact with eye and skin, once contacted, flush with water.Keywords :DTPMPA,DTPMPA China,Diethylene Triamine Penta (Methylene Phosphonic Acid)
