Coating process: fluorocarbon spraying process

Core tip: fluorocarbon spraying profile is a relatively new commodity in China, which is usually used for advanced construction Because of its excellent characteristics, it is paid attention to and favored by the construction industry, with excellent anti fading, anti air pollution and acid rain corrosion, and can accept the impact of various adverse weather, which is beyond the ordinary coating As a high-grade construction profile, the quality requirements of the whole technical process are extremely strict From the disposal process, spraying process to curing process, strict technical control is required to ensure the coating quality of aluminum profile The inspection specifications for the domestic culvert fluorocarbon spraying construction industry are as follows 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 Coating home news: fluorocarbon spraying profile is a relatively new commodity in China, which is usually used for high-level construction Because of its excellent characteristics, it is paid attention to and favored by the construction industry It has excellent anti fading, anti air pollution and acid rain corrosion, and can accept the impact of all kinds of adverse weather, which is beyond the ordinary coating As a high-grade construction profile, the quality requirements of the whole technical process are extremely strict From the disposal process, spraying process to curing process, strict technical control is required to ensure the coating quality of aluminum profile Gb5237.5-2008 is the primary basis for the inspection code of culvert fluorocarbon spray construction industry in China, which is recognized as the primary national standard for inspection of coating quality The function of fluorocarbon coating itself determines that it is necessary for spraying equipment to ensure excellent atomization effect, uniformity of spraying layer and dispersion of metal particles guessed by fluorocarbon coating, which directly affects the appearance effect of coating The fluorocarbon coating with uniform coating and excellent quality has metallic luster, obvious color and three-dimensional sense The use of inappropriate spraying equipment of fluorocarbon spray coating, there will be uneven color, surface shadow or coating is not solid, greatly affecting the decoration effect and use of fluorocarbon function The multi-layer spraying is often used in fluorocarbon spraying technology to give full play to the advantages of durability and weather resistance of metallic paint The pretreatment process is: degreasing alkali washing (degreasing) - water washing - chromizing - water washing - pure water washing, and then the spraying process is primer spraying - primer leveling - topcoat spraying - topcoat leveling - varnish covering - baking (curing) 1 The purpose of pre-treatment is that before spraying aluminum alloy profiles, the surface of the workpiece shall be degreased, decontaminated and chemically treated to produce chrome film The combination of coating and metal surface and anti-oxidation ability are added to extend the service life of the paint film 2 As the paint coating to close the substrate, the effect of primer coating is to improve the anti penetration ability of the coating, enhance the maintenance of the substrate, stabilize the metal surface layer, strengthen the adhesion of the surface of the topcoat, and ensure the color uniformity of the topcoat The paint thickness is usually 5-10 microns 3 Finishing coat is the most important layer of fluorocarbon spray coating, which supplies the decoration color needed by aluminum profile to make the appearance of aluminum reach the design demand Maintenance of metal surface is free from external atmosphere, acid rain and pollution corrosion, to prevent ultraviolet penetration, greatly enhance anti-aging ability, topcoat coating is the most thick layer of paint coating The coating thickness is usually 23-30 microns 4 Varnish coating is also called varnish coating The primary intention is to enhance the ability of the paint layer to resist external corrosion more effectively, maintain the finish coating, enhance the metallic luster of the finish color, make the appearance more colorful and dazzling, and the coating thickness is usually 5-10 microns 5 The furnace temperature of curing treatment is usually 180 ℃ ~ 250 ℃, and the curing time is 15-25 minutes Different fluorocarbon coating manufacturers will supply the best temperature and time according to their own coating 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,
