Introduction and application of thermoplastic powder coating performance

thermoplastic powder coating has the characteristics of heat softening, cooling and curing into a film, mainly physical melting plasticinto into a membrane processThermoplastic powder coatings were used earlier, as early as the mid-1940s, Europe has been studying the use of thermoplastic powder coatings development research and testing work also has more than 30 years of historythermoplastic powder coating has the characteristics of heat softening, cooling and curing into a film, mainly physical melting plasticinto into a membrane processThermoplastic powder coatings were used earlier, as early as the mid-1940s, Europe has been studying the use of thermoplastic powder coatings development research and testing work also has more than 30 years of historycan be applied as a variety of thermoplastic powder coatings, typical polyethylene, polypropylene, PVC, polyamide, thermoplastic polyester, chlorinated polatona, teflon and so onThermoplastic powder coatings are suitable for anti-corrosion coatings, wear-resistant coatings, non-toxic coatings and general decorative coatingsapplications are mainly chemical equipment, chemical pipelines, chemical storage tanks, plates, wire, mechanical parts, light industrial appliances and food industryWith the emergence of electrostatic spraying and static current bed method, the application range has been further expanded, instrumentation, electronics, machinery, automobiles, construction and other industries have their own applicationsin recent years, due to the expansion of the market, coating technology improvements, has been applied to the textile industryAt present, the application of thermoplastic powder coating has a new development, the use of a significant increasethermoplastic powder coating is characterized by simple processing and preparation, coating film with excellent chemical properties and good mechanical properties, some varieties with outstanding wear-resistant lubrication, the price is generally relatively lowBut this kind of resin powder is more difficult to crush, the particle size is coarser, the coating gloss and leveling is poor, the mechanical strength is not ideal, and the metal adhesion is poor, the drum generally need to be pre-coated primer to be able to usecomprehensive analysis has the following excellent characteristics1Excellent chemical stability2Light quality
3 Excellent electrical insulation performance 4 Excellent damping, wear-resistant performance, shock absorption, sound-cancelling performance The above characteristics of plastic powder make it widely used in industry in order to expand the application of thermoplastic powder coatings, further improve the heat resistance, rigidity and decorative properties of resins From the present point of view, in addition to adding a variety of auxiliary materials, can also use resin modification methods to achieve the desired effect recently, thermoplastic powder coatings have appeared a lot of modified varieties, there are a lot of improvements in the coating gloss, hardness, adhesion, elasticity and other properties, to meet some product coating requirements Such as: 1 The modified polyethylene of thin resin enhances the surface hardness and improves adhesion 2 Ethylene acetate copolymer modified polyethylene improves coating toughness and surround stress cracking 3 Polypropylene-modification polyethylene improves surface strength and improves mechanical strength 4 Poly-butt thin modified polyethylene improves mechanical strength and gloss 5 Cellulose acetate modified polyethylene improves strength and leveling performance 6 Polycarbonate modified polyethylene improves stress cracking and enhances durability 7 Epoxy resin modified polyamide improves anti-corrosion properties and enhances adhesion
