Detailed Description
Protective agent copper products
Performance of the goods: to make用本品treated by soaking in the dense layer of copper formed on the surface of the single-molecule protective film can be effectively isolated from the air and contacts the surface of copper to achieve the change to prevent corrosion. This product does not contain chromate, fluoride, peroxide, heavy metals and other toxic and harmful substances, without waste emissions, no pollution to the environment it is environment-friendly products, and would not affect the plating efficiency of the workpiece and welding performance, weak acid leaching to remove this protective layer. Brass and copper alloy in the surface of the protection of more inferior performance to prevent the brass color, fingerprints, speckle appearance and brass and copper alloy to maintain the original luster and does not affect any of its properties, 20% after the dilution ratio of the protective film can be more than 24-hour salt spray (NSS) test.
Scope of application: ① the application of materials: brass, copper alloy ② oil-free non-oxide layer on the clean surface;
﹑ Three physical indicators: 1, Appearance: transparent liquid 2, PH value of 7-7.5 3, the relative weight: 1.02 4. To deal with the area: the protection of each agent can handle kg copper 3-4 meters (according to the actual situation specific)
﹑ Using four methods: 1, oil in addition to oxides: degreasing → rinse → rinse → In addition to the oxide film (or gloss to deal with) → water rinse → rinse 2, copper protection to deal with: 1) use the proportion: 10% -100% ( need to be protected in accordance with the length of time, and select the appropriate concentration) 2) Temperature: ambient temperature -60 ℃ 3) processing time: 20 seconds -180 seconds (based on protection requirements, and select the appropriate time) 4) Stirring: mechanical stirring evenly 5) working equipment : stainless steel, glass, polypropylene, polyethylene and other materials storage devices 6) new fluid replacement: When there is no surface water film rupture phenomenon, with the protection of the new solution needed NOTE: Be sure when to clean the workpiece can not be brought into the copper, iron and other metal ion solution to work, or else to reduce the effect. In addition, the protection of the workpiece treated by the copper, not bare hand contact, so as to avoid pollution of the hands sweat rust. 3, pure water pure water rinse → rinse 4, drying or drying (60-70 ℃) → test → Five packaging, packaging and transportation specifications: Plastic barrel packing 25kg / barrel, as a general chemical transport, light light unloading, inverted to prevent the weight. Stored in well-ventilated place at room temperature. Two-year shelf life.
So用本品treated by soaking in the dense layer of copper formed on the surface of the single-molecule protective film can be effectively isolated from the air and contacts the surface of copper to achieve the change to prevent corrosion. This product does not contain chromate, fluoride, peroxide, heavy metals and other toxic and harmful substances, without waste emissions, no pollution to the environment it is environment-friendly products, and would not affect the plating efficiency of the workpiece and welding performance, weak acid leaching to remove this protective layer. Brass and copper alloy in the surface of the protection of more inferior performance to prevent the brass color, fingerprints, speckle appearance and brass and copper alloy to maintain the original luster and does not affect any of its properties, 20% after the dilution ratio of the protective film can be more than 24-hour salt spray (NSS) test.
