Pre-film passivation, pre-film corrosion of boiler, central air conditioning pre-film

Name: passivation pre-film, boiler pre-film corrosion Model: YL-013 Description: Metal pre-film deposition using advanced polymer formula, can quickly form a dense protective layer on the metal surface. Using a variety of complex configuration made of organic materials can be formed within 30 minutes to the high density of the passivation layer. Passivation film can effectively reduce the oxidation corrosion and electrochemical corrosion of metal surfaces, and can extend the life of equipment and downtime, and reduce the deposition of scale formation, to avoid the occurrence of corrosion under the scale, pre-film passivation has the speed Fast, low temperature deposition characteristics. Main purpose: This product is a new generation of green, non-toxic formulation, an alternative to traditional sodium nitrite passivation rust treatment process for handling all types of pre-film passivation after pickling, mainly used for all kinds of steel, stainless steel, copper, aluminum, titanium and other metals and various types of petroleum, chemical equipment, central air-conditioning system, thermal power plant steam turbine condenser and other heat exchangers passivation pre-film processing. Scope: all kinds of boilers, refrigeration equipment, pipe corrosion after cleaning pre-film. Product features: compact filming complete, fast, strong oxidation corrosion resistance, long life. Packing: 30kg / barrel plastic barrels,
