Properties
This product has structural features of both phosphonic acid and carboxylic acid group, which enable its excellent antiscale corrosion inhibition properties. Compared with widely used organophosphines, this product has excellent properties. Its antiscale property under high temperature is far better than that of organophosphines. It can also improve the solubility of zinc salt, has good chlorine oxidation capacity and good composite synergy.
Usage methods
PTBC is the widely used high efficient agent as composite antiscale corrosion inhibitor, it is also the excellent stabilizer for zinc salt. It is widely used in circulating cool water system and oilfield refill water system as antiscale corrosion inhibitor, especially suitable to composite with zinc salt and copolymer. It can be used in situations of high temperature, high hardness, high alkali and high index of condense multiples, it is used as chelating agent and metal detergent in lavation fields.
PBTC is usually used together with zinc salt, copolymer, organophosphine, imidazole and other water treatment agents. When used alone, the dosage of 5-15mg/L is preferred.
Package and Storage
25kg or 250kg in plastic barrel. Storage for one year in room shady and dry place.
Safety Protection
Acidity, Avoid contact with eye and skin, once contacted, flush with water.
