• Expiry Date:

  Apr 09,2018

• Detailed Description:

  Cas No. :37971-36-1 1,Properties:
  PBTCA has low content of
  phosphoric, has structural
  features of both phosphoric acid
  and carboxylic acid group, which
  enable its excellent scale and
  corrosion inhibition properties
  and better than other normal
  organic phosphorus acid,
  especially under high temperature
  its antiscale property is far
  better than that of normal
  organophosphines. It can improve
  zinc salt solubility, has good
  chlorine oxidation tolerance and
  good composite synergy.
  2, Specification:
  conform to HG/T 3662-2000

  3, Usage:
  As high-efficient agent of scale
  and corrosion inhibitor, PBTCA is
  one of the widespread used and
  good performing products. It is
  the excellent stabilizer for zinc
  salt. It is widely used in
  circulating cool water system and
  oilfield refill water system as
  scale and corrosion inhibitor,
  suitable to composite with zinc
  salt and copolymer. It can be
  used in situations of high
  temperature, high hardness, high
  alkali and high concentration
  index. In lavation fields, it is
  used as chelating agent and metal
  detergent.
  4, Application range&using method
  PBTCA is usually used together
  with zinc salt, copolymer,
  organophosphine, imidazole and
  other Water Treatment Chemicals.
  When used alone, the dosage of 5-
  15mg/L is preferred.
  Package and Storage:
  Normally In 25kg or 250kg net
  Plastic Drum, Storage for
  twelvemonth in room shady and dry
  place.
  Safety Protection:
  PBTC is Acidity, Avoid contact
  with eye and skin, once
  contacted, flush with water.
