    Core tip: powder coating is a new type, solvent free, 100% solid powder coating It has the advantages of no solvent, no pollution, saving energy and resources, reducing labor intensity and coating mechanical strength It has two major categories: thermoplastic powder coating (PE) and thermosetting powder coating Disadvantages: the powder on the corner is uneven, the film defects are difficult to cover up after curing, and the curing conditions are high Although the variety of powder coating is not as wide as solvent coating, it can be used as the polymerization of powder coating 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: powder coating is a new type, solvent-free, 100% solid powder coating It has the advantages of no solvent, no pollution, saving energy and resources, reducing labor intensity and coating mechanical strength It has two major categories: thermoplastic powder coating (PE) and thermosetting powder coating Disadvantages: the powder on the corner is uneven, the film defects are difficult to cover up after curing, and the curing conditions are high Although there are not as many kinds of powder coatings as solvent coatings, there are also many polymer resins that can be used as powder coatings Generally, it can be divided into thermosetting type and thermoplastic type 1 Thermosetting powder coating refers to a kind of hard coating which can not be dissolved or melted after heating with thermosetting resin as film-forming substance and curing agent for crosslinking reaction No matter how high the temperature is, the coating will not soften like the thermoplastic coating, but will only decompose The resin used in thermosetting powder coating is prepolymer with low polymerization degree and low molecular weight, so the coating has good leveling property and good decoration Moreover, the prepolymer with low molecular weight can form network crosslinked macromolecule after curing, so the coating has better anticorrosion and mechanical properties Therefore, thermosetting powder coating develops rapidly 2 Thermoplastic powder coating thermoplastic powder coating began to appear in 1950 It melts at spraying temperature and solidifies into film when it cools Because of the simple processing and spraying method, the powder coating only needs to be heated, melted, leveled, cooled or extracted and solidified to form a film, without complex curing device Most of the raw materials used are common polymers on the market, which can meet the requirements of service performance under most conditions But there are also some shortcomings, such as high melting temperature, low coloring level, poor adhesion with the metal surface and so on However, the commonly used thermoplastic powder coating still shows some special properties, among which polyolefin powder coating has excellent solvent resistance; polyvinylidene fluoride coating has outstanding weather resistance; polyamide has excellent wear resistance; PVC has good price / performance ratio; thermoplastic polyester powder coating has beautiful appearance and high artistic quality These characteristics make the thermoplastic powder coating occupy a large proportion in the coating market 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,
