    Core tip: electrophoretic paint, also known as electrophoretic paint With the emergence of defects in conventional spraying, electrophoretic coating has become more and more popular Electrophoretic paint has also been constantly updated, from anode electrophoretic paint to cathode electrophoretic paint, from single component electrophoretic paint to two-component electrophoretic paint The development of electrophoretic paint also promotes the development of electrophoretic coating, so that more and more products no longer use spraying technology but use electrophoretic paint The electrophoretic coating consists of water-soluble resin, pigment, filler, additive, solvent and neutralizer The principle of electrophoretic paint technology is as follows: 1 Electrophoresis is one of the most effective methods for coating metal parts Electrophoretic coating is Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: electrophoretic paint, also known as electrophoretic paint With the emergence of defects in conventional spraying, electrophoretic coating has become more and more popular Electrophoretic paint has also been constantly updated, from anode electrophoretic paint to cathode electrophoretic paint, from single component electrophoretic paint to two-component electrophoretic paint The development of electrophoretic paint also promotes the development of electrophoretic coating, so that more and more products no longer use spraying technology but use electrophoretic paint The electrophoretic coating consists of water-soluble resin, pigment, filler, additive, solvent and neutralizer The principle of electrophoretic paint technology is as follows: 1 Electrophoretic paint is one of the most effective methods for painting metal parts Electrophoretic coating is a kind of special coating method, in which the conductive coating is immersed in a tank filled with water and diluted with a relatively low concentration as an anode (or cathode), and a corresponding cathode (or anode) is set in the tank After a period of DC power is connected between the two poles, a uniform, fine and insoluble coating film is deposited on the surface of the coating 2 There are four chemical and physical changes in the process of electrophoretic coating: electrolysis, electrophoresis, electrodeposition and electroosmosis (1) Electrophoresis: under the action of electric field, the charged colloidal particles will swim towards the opposite charge electrode, which is called electrophoresis (2) Electrolysis: electrolysis refers to the decomposition of any conductive liquid when it is electrified For example, in an aqueous solution with a conductive medium, under the condition of direct current, oxygen is generated on the anode surface and metal dissolution occurs The phenomenon of hydrogen reduction and metal precipitation on the cathode surface is called electrolysis (3) electrodeposition: during electrophoretic coating, the charged particles (resin, filler and material) arrive at the opposite charged electrode under the action of electric field, neutralized by H (anode electrophoresis) Oh (cathode electrophoresis), and become water-insoluble film The film is very stable and uniform This process is called electrodeposition (4) Electroosmosis: the reverse process of electrophoresis If the electrodeposited particles adhere to a certain position, they do not move with the action of the electric field, and the dispersion medium moves in the opposite direction of its movement in the loose particles This electrochemical process causes the solvent to leach out and the mechanical bond of the electrodeposited film is strengthened This process is called electroosmosis 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,
