Uma igesi ingaphumanga ensimbi ngaphambi kokumbozwa ngempushana, izinkinga ezinjengamaqhubu, amabhamuza, namaphinifa angase avele.Umthombo wesithombe: TIGER Drylac
Emhlabeni wezimbozwe zempushana, izindawo zensimbi ezisansimbi njengensimbi, insimbi, ne-aluminium azibekezeleleki ngaso sonke isikhathi.Lezi zinsimbi zibamba amaphakethe egesi amagesi, umoya nokunye ukungcola ensimbi phakathi nenqubo yokuphonsa.Ngaphambi kokugcotshwa kwempuphu, indawo yokusebenzela kumele isuse la magesi nokungcola ensimbi.
Inqubo yokukhipha igesi efakiwe noma ukungcola ibizwa ngokuthi i-degassing.Uma isitolo singasuswanga kahle umoya, izinkinga ezinjengamaqhubu, amabhamuza, namaphinifa azoholela ekulahlekeni kokunamathela phakathi kokumbozwa kanye nokusebenza kabusha.I-Degassing kwenzeka lapho i-substrate ishisa, okwenza insimbi yande futhi ikhiphe amagesi avaleleke nokunye ukungcola.Kumele kuqashelwe ukuthi ngesikhathi senqubo yokuphulukisa ye-powder coatings, amagesi asele noma ukungcola ku-substrate kuzophinde kukhishwe.Ngaphezu kwalokho, igesi ikhishwa ngesikhathi senqubo yokukhipha i-substrate (ukukhishwa kwesihlabathi noma ukufakela).
Ngaphezu kwalokho, eminye imikhiqizo (njengezithasiselo ze-OGF) ingase yome ihlanganiswe nezindwangu zempushana ukusiza ukuxazulula lesi simo.Ngokufutha ngempushana yensimbi, lezi zinyathelo zingakhohlisa futhi zithathe isikhathi esengeziwe.Nokho, lesi sikhathi esengeziwe siyingxenye encane kuphela yesikhathi esidingekayo ukuze usebenze kabusha futhi uqale kabusha yonke inqubo.Nakuba lesi kungesona isixazululo esingenangqondo, ukusisebenzisa ngama-primer akhiwe ngokukhethekile namajazi angaphezulu kungasiza ekudambiseni izinkinga zokukhipha umoya.
U-2020 uzovela ngaphambi kokuthi wazi.Lokhu kuphawula ukuqala kweshumi leminyaka elisha futhi kuletha izinguquko emhlabeni ngendlela esiwazi ngayo.
Sekuyiminyaka engaphezu kwengu-50, imibhede enamanzi isetshenziselwe ukumboza izingxenye nge-powder coating.Kulesi sihloko, ochwepheshe ababili bezimboni baxazulule izinkinga ezithile ezijwayelekile ezihlobene nenqubo yombhede omanzi…
