Usage:
The agent is a pre-film agent of full organic formula, with strong anti-corrosion function and anti-corrosion function, which can be used in the system of different materials, different temperatures and different conditions. Pre-film agent and solution of Ca2+, Zn2+, Fe2+ play a synergistic role in the formation of insoluble chelates, and in the carbon steel surface is constantly deposited, while particles gradually grow up, and ultimately form a dense oxidized film and passivation film, the surface of the carbon steel is basically completely covered; the cathode and the anode corrosion process have obvious inhibitory effect; can make the production operation of the scale inhibitor and retardation of the corrosion of the twice the effort effect.
After closing the circulating water system sewage, according to the system retained water for impact dosing, the initial dosage is generally 200-300mg/L, need to be based on the total phosphorus content in the circulating water for the appropriate amount of supplemental dosage, supplemental dosage is generally 20-50mg/L, to maintain total phosphorus content in the circulating water in the 20mg/L or more, running 24h~48h or so.
Packaging and storage: 25kg plastic drum or 1t square drum, stored in a cool place, low temperature storage with crystal precipitation, does not affect the effect. Storage period of twelve months.
