Powder coatings have a completely different form from ordinary coatings, which exist in the state of micro-fine powder. Since no solvent is used, it is called powder coating. It is a new type of solvent-free, 100% solid powder coating. It has the characteristics of not using solvent, harmless, non-polluting, saving energy and resources, environmental protection, reducing labor intensity and coating film mechanical strength and so on. Because it is 100% solid powder coating, it can be sprayed automatically, oversprayed or oversprayed, and can also be recycled with a recovery system to recycle the excessive part of the coating, reducing environmental pollution, convenient and convenient, and it is a kind of coating worthy of promotion.
Thermosetting powder coating is generally composed of resin, curing agent, pigment, filler and additives. It is a hard coating formed by heating thermosetting resin as a film-forming material and adding a curing agent that reacts with cross-linking. It has good decorative properties, and because the low molecular weight prepolymer can form a network of cross-linked macromolecules after curing, it also has good corrosion resistance and mechanical properties.
Izikhala zezinto ezithambile zokucasha
Ezimnandi kanye nezokwenza okuluhlaza: ukususa ukulungiswa kwezinto eziningi ezinamandla zokwenza izinto ezithile ezihlukene zokubeka i-film-forming, ukususa, ukwenza isilonda, ukwenza isilinganiso, ukwenza ukuphila okungapheli kanye nokungabulala izithelo ezinamandla ukuze kufikeleke ekusebenziseni kwamandla wezinto.
Ukuphakamisa okusezingeni eliphezulu kanye nokugcina: izinto ezimbi zokwenza zinamandla ezingu-20-50% noma izinto ezimbi zokwenza, kodwa i-powder coating, akukho amanzi noma amandla, iyona into esolwa kahle, ekuphileni kanye nokugcina okusalungile, ngaphandle kwezinto ezinamandla noma amanzi, uma isimo sokuphakamisa nokugcina kusheshisa kunalowo 0 ℃, kungcono ukugcina, i-powder coating ayinayo le nto.
Akukho amaphreservatives: Ezinye izinto zokwenza ezimbi, kukhona amanzi kanye nezinto ezinamandla zokudla izilonda, ezitholakala kahle ngabanye abantu. Ngakho, ukuze kungakhathaliseki, kufanele kube nokufaka amaphreservatives, kodwa i-latex powder coating ayinayo izinkinga zokudla izilonda, akufanele kube nokufaka amaphreservatives.
Isiqwashiso se-Paint: Ngokusho kwezinto ezimbi zokwenza isiqwashiso se-paint, le coating ingase ikhululwe kahle, ngakho kufanele kube kusho ukuthi iyakwenza futhi iyakwenza.
Okwenziwe ukuthengiswa: Ngesikhathi sokwenza, i-powder coating ingase iyenziwe ngokusebenzisa isakhiwo esispecial, futhi i-powder ethengwayo ingase iyahlukaniswa ekupheleni kwe-powder entsha ngesimo esetshenziselwa ukwenza ukusebenzisa okulandelayo. Lokhu kwenza ukuthuthukisa okusebenzayo kanye nokwakha okuphakathi kwesisebenzisa sezinto.
