Coating classification: metal powder coating

Core tip: metal powder coating refers to all kinds of powder coating containing metal powder (such as copper gold powder, silver aluminum powder, etc.) 1 Characteristics of metal powder 1.1 to reduce environmental pollution, no volatile solvents such as organic solvent and water are used for powder coating, so the powder coating is inorganic solvent type coating, which greatly reduces the potential safety hazards caused by solvents, such as organic solvent poisoning events caused by operators due to the presence of organic solvent, or fire caused by organic solvent, etc Since the powder coating appeared in the 1950s and 1960s 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 Coating home news: metal powder coating refers to a variety of powder coating containing metal powder (such as copper gold powder, silver aluminum powder, etc.) 1 Characteristics of metal powder 1.1 reduce environmental pollution powder coating does not use organic solvent, water and other volatile solvents, so the powder coating is inorganic solvent based coating, which greatly reduces the potential safety hazards caused by solvents, such as organic solvent poisoning caused by operators or fire caused by organic solvent Since the powder coating appeared in the 1950s and 1960s, there has been no major safety accident caused by powder coating Powder coating is 100% solid powder coating, fully automatic spraying can be used Excessive or super spray powder coating can be recycled through the recovery system device, so the utilization rate of powder coating can reach nearly 100%, which can reduce the disposal of waste in the coating industry and reduce the degree of environmental pollution to the minimum 1.2 excellent coating performance metal powder coating is metallic luster, with gorgeous multi-color effect and outstanding protection function, providing colorful appearance decoration for high-end industrial products such as automobiles, home appliances, instruments and meters As long as the powder coating is directly sprayed on the iron or aluminum materials that have been properly pretreated, the coating surface with excellent performance can be obtained after baking, such as the durability of the coating, including: abrasion resistance, impact, adhesion, toughness, corrosion resistance and chemical resistance In addition to the above advantages, the powder coating for outdoor use also includes high weather resistance and pollution resistance Especially for the thicker coating, the powder coating can reach 50-300 μ m at a time, and has good leveling property, so it will not drop or accumulate when the solvent coating is thick In order to improve the multi-function of powder coating, we can adjust the color, luster and surface flatness according to the customers' preferences, even special metal powder coating and some special wrinkle powder coating 2 Classification of metal powder coating 2.1 according to the flatness of film appearance, according to the flatness of film appearance, it can be divided into two categories: plane type and texture type According to the appearance gloss effect of the film, the plane type metal powder coating can be divided into high gloss, flash (colorful, color with angle), metal effect Flash and metal effect products have been widely applied to the surface coating of high-end cars; according to the texture effect of the film appearance, the metal powder coating can be divided into hammer, sand and speckle 2.2 according to the type of metal pigment, it can be divided according to the type of metal pigment At present, aluminum powder, copper powder and zinc powder are the basic metal pigments that can be widely used in the powder coating market, mainly including Eckart, Schlenk, Wolstenholme and a few domestic manufacturers People are used to distinguish the powder coating into silver powder (AL), gold powder (Cu) and zinc rich powder (also known as zinc rich powder) according to the use of gold pigments Zinc based coating, Zn) 2.3 according to the function of the coating film, it is mainly divided into two categories: decorative and protective Decorative products have common decorative and high decorative properties; protective products have weather resistance and anti-static (conductive) products 3 The production process of metal powder coating the formation of metal coating effect of powder coating is realized by adding metal pigment There are two main ways of adding: melt extrusion method and dry mixing method In the actual production, the two processes have been continuously improved and improved 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,
