Common knowledge of coating: significant advantages of powder spraying for aluminum profile surface treatment

Core tip: the surface treatment methods of aluminum profiles generally include anodizing, electrophoretic coating and powder spraying, each of which has its own advantages and occupies a considerable market share Among them, powder spraying has the following significant advantages: 1 The process is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process For some main technical parameters, microcomputer control has been realized, which effectively reduces the difficulty of process operation, and greatly reduces the auxiliary equipment; 2 The yield is high In general, if the measures are appropriate, the unqualified products can be controlled as much as possible Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Coating home news: the surface treatment methods of aluminum profiles generally include anodizing, electrophoretic coating and powder spraying, each of which has its own advantages and occupies a considerable market share Among them, powder spraying has the following significant advantages: 1 The process is relatively simple, mainly due to the improvement of the automatic accuracy of the main equipment in the production process For some main technical parameters, microcomputer control has been realized, effectively reducing the difficulty of process operation, while the auxiliary equipment is greatly reduced; 2 The yield is high Generally, if the measures are appropriate, the production of unqualified products can be controlled to the maximum extent 3 The energy consumption is significantly reduced In the production process of ordinary anodizing and electrophoretic coating, the consumption of water and electricity is quite large, especially in the oxidation process The output current of the rectifier can reach between 8000-11000a, and the voltage is between 15-17.5v In addition to the heat consumption of the machine itself, it needs to keep cooling with circulating water The power consumption per ton is often about 1000 degrees, and the reduction of auxiliary facilities can also reduce some power consumption; 4 The pollution degree of water and air is reduced, flake alkali, sulfuric acid and other liquid organic solvents are no longer used, water and air pollution are reduced, the competitive strength of aluminum profile and plastic steel profile as environmental protection products is effectively improved, and some production costs are correspondingly reduced; 5 The labor intensity of workers is obviously reduced Because of the use of automatic assembly line, the way of loading and the way of using fixture have been greatly simplified, the production efficiency has been improved, and the labor intensity has also been reduced; 6 The surface quality standard of the raw material is obviously reduced The powder coating can completely cover the extrusion lines on the surface of the profile, cover up the defects on the surface of some aluminum profiles, and improve the surface quality of the finished aluminum profile 7 some physical indexes of the coating film are obviously improved compared with other surface treatment films, such as hardness and wear resistance, which can effectively extend the service life of the aluminum profile Powder coating is used for powder spraying, and electrostatic spraying is used for technology Under the influence of acceleration wind, the powder particles carry positive charge when they are ejected from the gun body, contact with the profiles with negative charge, generate electrostatic adsorption, and then undergo high-temperature solidification It also enhances the adsorption strength of the paint and prevents the paint film from falling off From the perspective of technology itself, it has a relatively high scientific and technological composition, the deployment of different colors of paint, the production of different color system of decorative effect, more in line with the needs of interior decoration, is also consistent with the application of aluminum profiles in the construction industry to the trend of indoor development In particular, the combination of spraying profile and thermal insulation broken bridge makes it more fashionable, which makes the powder spraying profile have a greater development space, and it is also irreplaceable for profiles produced by other processing methods 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,
