Function:
    It is composed of polyphosphate and non-ionic surfactant, easy soluble in water, fast removing oil sludge and preliminary rust in heat exchanger, make metal surface lustrous and be in active state, form a layer of uniform protective film on their surface to effectively prevent metal from corrosion. It is used to clean pre-film in recirculated cooling water system.

Specification:
    Appearance: offwhite liquid
    Solid Content: >40%
    Phosphate Content(PO₄^3-):>30%
    PH(1% aqueous solution):6.0-7.0
    Mutually soluble in water

Usage:
    It is used to clean pre-film in heat exchanger and pipes of recirculated cooling water and oil pipeline in refinery, fertilizer factory, chemical factory, hotel and restaurant, etc. The use concentration is 800-1200mg/L if equipment are under operation, the appropriate pH is 5.5-6.5, the usual treatment time is 48 hours under cool state.

Package and Storage:
    plastic drum(net weight: 25kg/drum), stored in shady and cool place. It can be stored for a long time because of its stable quality, but easy demixing. Quality remain same after mixing uniform.
