Coating classification: cathodic electrophoretic coating

The key points are as follows: cathodic electrophoretic coating is a special method of film formation, with the coating as the cathode, and the electrophoretic coating used is cation type (with positive charge) It is to dip the coating with conductivity into the electrophoretic coating tank diluted with full water and with relatively low concentration as the cathode, and set the anode corresponding to it in the tank, and apply direct current between the two poles A coating method in which a uniform, water-insoluble film is deposited on the coating Characteristics of cathodic electrophoretic coating 1 Compared with the traditional solvent coating and other dipping and spraying water-based baking coatings, cathodic electrophoretic coating has incomparable advantages: coating Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: cathodic electrophoretic coating is a special coating The formation method takes the coated object as the cathode, and the electrophoretic coating used is cationic type (with positive charge) It is a kind of coating that the conductive coated object is immersed in the electrophoretic coating tank diluted with full water and with relatively low concentration as the cathode, and the corresponding anode is additionally arranged in the tank, and the direct current is applied between the two poles to precipitate uniform and water-insoluble coating film on the coated object Method The characteristics of cathodic electrophoresis coating 1 Compared with the traditional solvent coating and other dip coating and spray water-based baking paint, cathodic electrophoresis coating has incomparable advantages: the primer coating process can be fully automated, which is suitable for large-scale flow production; uniform film thickness can be obtained; the permeability is good, which improves the corrosion resistance of the inner cavity of the workpiece, especially the corrosion resistance of cathodic electrophoresis coating; The utility rate of the coating is high, the safety is relatively high, it is a low pollution coating, the appearance of the coating is good, and it has good flattening when drying 2 Compared with the anode electrophoretic coating method, it has the following advantages: the coating does not have anode dissolution, which improves the adhesion and anti-corrosion performance of the coating and the substrate; the paint base contains groups (such as nitrogen groups) to prevent the substrate from corrosion, and the corrosion resistance and penetration are higher than that of the anode electrophoretic coating, so that the inner cavity and weld of the coating are better Cathodic electrophoretic coating performance cathodic electrophoretic coating has excellent corrosion resistance, permeability and decoration performance, which is not only used in the automobile industry, but also widely used in other industries For example, in building materials, fire doors, steel windows, etc are coated with two coats of epoxy resin cathodic electrophoretic coating with good weather resistance, and steel furniture and wall materials are coated with acrylic resin cathodic electrophoretic coating In addition, cathodic electrophoresis is also used in the deposition of metal oxides and the preparation of metal films to obtain materials with special properties For example, znco204 can be electrodeposited on a nickel based electrode as a catalyst for oxidation reaction, which can obtain a electrode with good catalysis and mechanical stability The high-purity zinc oxide powder prepared by the solid-state pyrolysis reaction is electrodeposited to form high-quality zinc oxide film, which can emit ultraviolet light with a wavelength of 390 nm at room temperature Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
