by Powder coatings VOC content material is low,Guest Posting smooth to clean, overspray paint is recyclable; after production the coating film become appreciably no pinholes, became generally easier to paintings than the liquid paint, the formed coating film with suitable sturdiness. Powder coating is the 1960s began to broaden a coating new varieties, new technology, has keep power and resources, reduce environmental pollutants, simple process, easy to automate, coated durable, pollutants-unfastened, excessive exertions productiveness, powder is recyclable and different characteristics.
The last 30 years, as countries increasingly more strict environmental safety requirements, the traditional solvent-based totally coatings improvement was constrained, powder coatings as environmentally-pleasant paint has tremendous development, however we have to also honestly to look that, so far, powder coating manufacturing additionally accounted hodgdon retumbo for most effective five% of the complete coating, liquid coating also occupy absolutely the share, as much as ninety five%. In ultimate 10 years, the powder coatings became rapidly developing, a variety of of latest merchandise, new technology had been advanced, low temperature curing powder coatings, first-rate weatherability powder coating, acrylic powder coating, MDF used powder coatings, glass and plastic used powder coating; supercritical era, steel powder coating technology were put into the bond market.
Powder coatings may be divided into thermoset and thermoplastic classes. Thermosetting powder coating: have good decoration, corrosion resistance and mechanical properties, specifically utilized in insulation, corrosion and construction and different elements. Epoxy powder coating: specially used in indoor metal fixtures merchandise, automobile elements and oil and water pipelines. Polyester powder coating: with high gloss, suitable leveling and different capabilities, generally used for instrument housing, furniture and other fields. Acrylic powder coating: have thermoplastic and thermosetting types. Thermosetting acrylic resin powder coating has great climate resistance, color retention, stain resistance, and so forth., suitable for decorative powder coatings.
Thermoplastic powder coatings had been specifically utilized in mechanical parts, mild system and other factors of the meals industry. PVC powder coating: has brilliant solvent resistance. Mainly used for coating metallic mesh panels, metallic furniture, chemical equipment and so on. Polyethylene powder coating: has splendid anti-corrosion, electrical insulating homes and resistance to ultraviolet radiation, etc, the drawback is the mechanical electricity now not excessive, bad adhesion to the substrate. Can be used for chemical pool, tank, automotive elements and so on. Nylon powder coating: non-poisonous, tasteless, not mildew erosion, suitable for the spraying meals industry parts, drinking water pipes and meals packaging. Fluororesin powder coating: a fluorine-containing polymer can be prepared many exclusive types of powder coatings, along with polytetrafluoroethylene, polychlorotrifluoroethylene, polyvinylidene fluoride and so forth. Polytetrafluoroethylene with high melting factor, excessive corrosion resistance, was utilized in oil, sealed and non-stick coating. Polychlorotrifluoroethylene carried out in anti-corrosion equipment of chemical, pesticide manufacturing unit. Polyvinylidene fluoride powder coating incredible in weather resistance, and no dirt absorption, easy to maintain original luster.
