Die-cast aluminum passivating agent, Pingxiang aluminum passivating agent, in addition to oil factory in Jiangxi

Nanchang Maple Chemical Co., Ltd., is a wholly owned subsidiary of Shenzhen Maple Chemical Group, is specialized in environmentally friendly metal surface treatment, after treatment, water treatment agent development, production and marketing of high-tech enterprises supply: acid degreasing agent, alkali degreasing agent, neutral degreasing agent, Al degreasing agent, zinc phosphate solution, iron phosphate solution, silane treatment agent, nano-ceramic agent, chromium-aluminum coating, wax water, ash agents, paint remover, rust inhibitors, industrial waste water plants, heavy metal scavenger, water purification agents, etc. length of time required passivation passivation solution should be determined according to when a certain temperature and concentration, the passivation time is short, thin films , pale. In low concentrations of chromic acid passivation solution, the passivation film forming rate greater than the dissolution rate of the film, along with the extension of the passivation time how to sell aluminum passivating agent, the film constantly thickening. Passivation time is too long, the film will become porous, the bonding strength is low, the lack of color film is not shiny Moreover, due to the excessive dissolution of the coating, corrosion resistance decreases when the passivation longer than 3s, the corrosion performance dramatically decline. At a temperature and concentration used, metal deactivators time is preferably controlled to 30 seconds. Nanchang Maple Chemical Co., Ltd. aluminum passivating agent, is a wholly owned subsidiary of Shenzhen Maple Chemical Group, is specialized in environmentally friendly metal surface treatment, after treatment, water treatment agent development, production and marketing of high-tech enterprises Supply: acid degreasing agent, degreasing agent alkaline, neutral degreasing agent, Al degreasing agent, zinc phosphate solution, iron phosphate solution, silane treatment agent, nano-ceramic agent, chromium-aluminum coating, polishing wax, ash agent, paint remover, rust inhibitors, industrial wastewater plants, heavy metal scavenger, water purification agents, etc. metal degreaser mostly on oil processing parts surface, degreasers separable from a chemical point of view pickling degreasers, alkaline degreasers, they both usage is not the same apply in different situations, according to their number of solvent content of the metal surface oil, have the following classification: by PH Category: 1, a solvent PH value greater than 7 is alkaline degreaser 2, a solvent PH value is equal to 7 is neutral degreaser 3, PH value in less than 7 are acidic solvent degreasers reaction temperature according to two classifications: First: the temperature in addition to oil temperature is lower second: room degreaser temperature controlled at 20 degrees on it. The product "Steel Acid Degreaser C / BW-500C" degreasing effect, the depth of the protection of parts of the surface, the front surface coating, maintenance, plating, immersion plating treatment and other industries use the most. Nanchang Maple Chemical Co., manufacturers offer aluminum passivating agent, it is a wholly owned subsidiary of Shenzhen Maple Chemical Group, is specialized in environmentally friendly metal surface treatment agent aluminum passivating agent production plant, post-processing, water treatment agent research , production and marketing of high-tech enterprises supply: acid degreasing agent, alkali degreasing agent, neutral degreasing agent, degreasing agent aluminum, zinc phosphate solution, iron phosphate solution, silane treatment agent, nano-ceramic agent, no chrome aluminum coating, wax water, ash agents, paint remover, rust inhibitors, industrial waste water plants, heavy metal scavenger, water purification agents, etc. phosphate film is a series of different sized crystals composed in crystal The porous structure of small cracks formed on the connection point. The crystal structure of the porous so that the corrosion resistance, the steel surface adsorption, abrasion resistance can be improved and enhanced. Phosphate coating is mainly used in paints, electrophoresis, electrostatic spraying, dusting the bottom, in order to enhance the binding force of the iron matrix with phosphate coating and improve the corrosion resistance, the coating weight is generally 0.4-3g / m2, a thickness of 0.5 3μm, microcrystalline Valley granular, preferably spherical crystals. It can also be used to prevent corrosion underlying oiled, cold lubrication, reducing film lubrication, electrical insulation. Die-cast aluminum passivating agent, Pingxiang aluminum passivating agent, in addition to oil factory in Jiangxi Nanchang provided by Maple Chemical Co. Nanchang Maple Chemical Co., Ltd. (www.hp-chemical.com) strong, credible, Nanchang in Jiangxi Province, chemical products and other industries has accumulated a large number of loyal customers. The company better work attitude and constantly improving innovative ideas will lead Maple chemical into the brilliant and you work for a better future!
