Paint material selection: classification of automotive coatings

Core tip: there are more and more means of transportation when you go out From walking to bicycles, electric cars, and buses to subways, the most convenient way is to travel freely For the maintenance of the car, I think everyone has their own way, including paint From a professional point of view, automotive coatings can be divided into several categories: 1 According to the shape of the coating, it can be divided into water-based coating, solvent based coating, powder coating, high solid based coating, etc.; 2 According to the construction method, it can be divided into brush coating, spray coating, roll coating, dip coating, electrophoresis coating, etc; 3 According to the construction process, it can be divided into primer, intermediate coat, paint (two coats of primer), finishing coat, finishing coat, etc 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 Paint Home News: out, more and more means of transportation, from walking to bicycles, electric cars, from buses to subways, the most convenient or nothing more than cars, free travel For the maintenance of the car, I think everyone has their own way, including paint From a professional point of view, automotive coatings can be divided into several categories: 1 According to the shape of the coating, it can be divided into water-based coating, solvent based coating, powder coating, high solid based coating, etc.; 2 According to the construction method, it can be divided into brush coating, spray coating, roll coating, dip coating, electrophoresis coating, etc; 3 According to the construction process, it can be divided into primer, intermediate coat, paint (two coats of primer), finishing coat, finishing coat, etc; 4 According to the function, it can be divided into decoration coating, anticorrosive coating, conductive coating, antirust coating, high temperature resistant coating, temperature indicating coating, heat insulation coating, fireproof coating, waterproof coating, sound insulation and vibration damping coating, etc in general, the common features of automobile coating are as follows: (1) covering power: the covering power is usually expressed by the weight of the coating required to make the specified black-and-white grid cover, and the larger the weight, the smaller the covering power (2) coating adhesion: refers to the adhesion between the coating and the base (3) viscosity: the viscosity affects the construction performance Different construction methods require different viscosity of the coating (4) fineness: fineness directly affects the smoothness and luster of the coating surface (5) pollution resistance (6) durability: including freeze-thaw resistance, scrub resistance, aging resistance (7) alkali resistance: the decorative object of the paint is mainly some alkaline materials, so alkali is an important characteristic of the paint (8) minimum film forming temperature: each coating has a minimum film forming temperature, which is different for different coatings Continue to pay attention to building materials home, bring you the most intimate and convenient service“
