How could we forget the sulfate galvanized conversion when we talked about the process characters of galvanized steel pipe. Today, as manufacturer of steel pipes, Threewaysteel pipe company would have a list for sulfate galvanized conversion in hot galvanized steel pipe.
Sulfate galvanized conversion:
Sulfate galvanized ferroalloy retains only the main salt of zinc sulphate zinc sulfate, and the remaining components, such as aluminum sulfate, alum (potassium aluminum sulfate) can be added in the treatment. This would finally lead to the formation of insoluble hydroxide precipitate precipitation. For organic additives, we can add powdered activated carbon adsorption to remove it. Tests showed that aluminum sulfate and potassium aluminum sulfate is difficult to completely remove in once. And this has a certain degree influence for brightness for brightness of the coating, but it is not serious, as it can be taken out of consumption, which make coating brightness can be restored. The solution passed the treatment, according to the new Process ingredients required additional content, that is the final complete the conversion.Stripped Sunflower Seeds
The quality of the galvanized layer can be evaluated by the weight of the zinc plated on the substrate, the bonding force between the galvanized layer and the substrate, and the uniformity of the coating. The uniformity of the zinc layer is an important quality indicator of the zinc coating. In general, the corrosion always starts at the thinnest part of the zinc layer and spreads around, resulting in rust, broken wires and affecting the service life. For the coating weight and bonding strength, each standard has clear regulations, but the uniformity is different. In the 1970s, the ISO standard and the standards of various countries in the world generally stipulated that the copper sulfate test should be used for inspection. By the 1980s, with the exception of Japan and the former Soviet Union, ISO standards and standards around the world no longer adopted this method. Although our country has retained this method in some standards such as GB/T15393-94 "Steel wire galvanized layer" in the form of "can be carried out by mutual agreement", most of them are no longer adopted. However, the old zinc coating uniformity detection method has been abandoned but no corresponding new methods have been established. In addition, there is no uniform definition and requirement for uniformity, so that some producers do not monitor and detect the uniformity of the coating well. , So as to affect the further improvement of product quality
The color-coated steel strip using hot-dip galvanized steel strip as the base material is protected by the zinc layer, and the organic coating on the zinc layer plays a role of covering and protection to prevent the steel strip from rusting. PRODUCT DESCRIPTION Product Properties The prepainted steel coil is a flat steel product coated with protective decorative paint. The polymer coating is available in a wide range of colors, as well as matte, glossy or decorative natural finishes (granite, wood, etc.). The prepainted galvanized steel coil is a color-coated steel strip protected by a zinc layer on a hot-dip galvanized steel strip base material. Organic coated galvanized steel is corrosion resistant, has excellent mechanical properties, plays a role in covering and protecting the steel strip from rusting, and can be formed, shaped or stamped. Brand: Xinnorda Standard: GB; ASTM; A792M Steel grade: Q235; Q345 Certification: ISO Surface treatment: spraying Technology: spraying after chemical degreasing and chemical conversion treatment, baking and curing. Application: Advertising industry, construction industry, home appliance industry, electrical appliance industry, furniture industry and transportation industry The color-coated steel strip uses a hot-dip galvanized steel strip as the base material is protected by the zinc layer, and the organic coating on the zinc layer plays a role of covering and protection to prevent the steel strip from rusting, the service life is longer than that of the galvanized strip. The color-coated rolls have a lightweight, beautiful appearance and good corrosion resistance. The colors are generally divided into gray, sea blue and brick red.
