Pre-film passivation

Brief pre-film passivation purposes, pre-film passivation characteristics of the passivation pre-film passivation pre-film method using a variety of organic materials using complex formula can in 30min dense passivation layer can be formed. 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 characteristics of the passivation pre-film deposition purposes, pre-film passivation characteristics of the passivation pre-film use detailed, pre-film passivation characteristics of the passivation pre-film passivation method using pre-film passivation pre-film passivation pre-film national patent applications. The use of advanced film-forming polymer formulation can quickly form a dense protective layer on the metal surface. Complex formula using a variety of organic materials can be dense passivation layer can be formed in 30min. 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. Product characteristic pH value: 9-11 Appearance: liquid specific gravity: 1.12 ± 0.02 flammability: Do not burn the use of features rapid deposition: passivation film can be formed rapidly widely used in metal surface: carbon steel, stainless steel, copper and other materials are can be pre-film passivation security and stability: The product has no corrosive effect on metal Material Range: Any device carbon steel, low alloy steel, cast iron, stainless steel, copper and copper alloys, aluminum and aluminum alloy passivation: metal surface passivation pre-film concentration: 2% to 3%
