Coating process: cold galvanizing paint matching coating construction process

It is suggested that the cold galvanizing paint has obvious advantages in the field of cathodic protection due to its high content of zinc powder in the paint film, and gradually replaces the traditional hot galvanizing process Cold galvanizing paint is widely used in the field of power With the development of national power projects, the anti-corrosion coating of power equipment, high-voltage tower and so on becomes particularly important The supporting coating of cold galvanizing paint takes anti-corrosion of electric tower as an example This paper only describes the paint coating, but does not explain the transportation, installation and acceptance of steel surface treatment Power tower is mainly steel structure base material To achieve high-quality coating effect, the surface 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 Home of coatings: due to the high content of zinc powder in the paint film, cold galvanizing paint has a very obvious advantage in the field of cathodic protection, and gradually replaces the traditional hot galvanizing process Cold galvanizing paint is widely used in the field of power With the development of national power projects, the anti-corrosion coating of power equipment, high-voltage tower and so on becomes particularly important The supporting coating of cold galvanizing paint takes anti-corrosion of electric tower as an example This paper only describes the paint coating, but does not explain the transportation, installation and acceptance of steel The surface treatment of power tower is mainly steel structure base material In order to achieve high quality coating effect, the surface treatment is very important Sand blasting shall be carried out for steel to remove rust and impurities on the surface, and cleaning agent shall be selected to wipe the surface to remove oil stains The surface roughness of steel shall reach 30-70 μ m, meeting the Swedish standard of Sa2.5 rust removal After finishing the surface treatment, it is necessary to apply cold galvanizing paint within 4 hours to avoid steel reoxidation Primer coating cold galvanizing paint adopts high-pressure airless spraying, and special diluent is added into the paint to fully mix evenly The film thickness is recommended to be 80-100 microns During the spraying process of cold galvanized paint, the paint materials need to be continuously stirred to avoid the precipitation of zinc powder At the same time, the paint film cannot be sprayed too thick to prevent the paint film from cracking The use of the sealer is to avoid blistering of the next paint film The surface roughness of the cold galvanized paint is large, which is likely to cause blistering on the surface of the coating Before coating, it is necessary to check whether there is zinc salt on the surface of cold galvanized paint If there is zinc salt, it shall be removed in time to avoid affecting the adhesion The sealer can be hd1500 epoxy sealer, and the recommended film thickness is 25-40 microns Epoxy micaceous iron intermediate paint can be selected as the intermediate paint for intermediate paint coating The paint has very good shielding and anti-corrosion characteristics It is suitable to spray 1-2 courses under high pressure and the film thickness is 100 microns Weather resistant coating is required for finishing coat, which usually includes acrylic polyurethane finish, fluorocarbon finish, etc., which can be applied according to the design requirements Recommended film thickness is 60-80 microns 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,
