Special steel passivation agent

1. Scope: This passivating agent for steel, steel, aluminum, galvanized steel or galvanized passivation, increase the corrosion resistance of the metal, paint or plastic film to increase paint adhesion and resistance to deformation forces. The product compared with conventional spray type or immersion-type process, the biggest feature is fast, passivation without water. 2. Bath control: The product roll coating process. Each 1000L bath was added 100 ~ 300kg, specifically in proportion to the actual production line and the film thickness required to determine the optimum process conditions by our technical staff according to the actual situation. Diluted with water at room temperature, can be spray or dip process, the metal surface passivation solution remaining available drum squeezed, roller coating technology can also be used directly passivation. Acid concentration is controlled by measuring point, the surface film passivation weight of 0.05 ~ 0.3g / m2. 3. Process: washing → brushing (if necessary) → washing → washing → passivation → drying pretreatment before cleaning and washing passivated metal surface dirt must be completely removed. Scrub: In the brushing process, to continue to add water and use the water cycle. Cleaning and degreasing: alkaline and acidic cleaners washing: After washing must be carefully cleaned, and preferably a multi-stage washing. Washing time: Temperature: 20 ~ 60 ℃ passive temperature: room temperature drying: steel Maximum temperature: 80 ~ 160 ℃ after treatment: immediately after drying and cooling passivation, if necessary, immediately painted or coated. 4. Storage: The product should be stored at room temperature environment in a cool ventilated room, the shelf life of 1 year. 5, the device material: The following applies to all metal equipment and LH-118 type contact passivating agent bath; nickel-chromium steel, material No. 1.451, nickel-chromium-molybdenum steel, material number 1.4571 PVC, polypropylene: water (alkaline degreasing agent) for the main tank, spray channels, pumps, sprinkler pipe and nozzle DINEN10025 use ordinary structural steel. 6. Safety: It is recommended operator should wear protective equipment when using this product, avoid eye, skin is exposed to the product.
