Njengomthetho, ukugqoka kunemisebenzi emibili eyinhloko: ukuhlobisa nokuvikelwa okubaluleke kakhulu kwezomnotho. Izembatho ezisebenzayo zingase zisetshenziswe ukushintsha izakhiwo ezingaphezulu ze-substrate, njengokunamathela, ukumanzisa, ukumelana nokugqwala, noma ukumelana nokugqoka. Embonini yensimbi, ukunamathela ngopende noma ukunamathela okuyimpushana ikakhulukazi kuvikela ipayipi lensimbi elishiselwe ekugqwaleni, kanye nokugcina ukubukeka okuhle kwepayipi.
Amapende nama-lacquers yizinhlobo ezimbili ezinkulu zezinto ezisetshenziselwa ukumboza ezisetshenziswayo. Ngobuchwepheshe, upende yinto evame ukusetshenziswa kakhulu ukuvikela insimbi emshinini wokugaya. Amasistimu kapende wezakhiwo zensimbi athuthukile phakathi neminyaka edlule ukuze ahambisane nomthetho wezemvelo wezimboni kanye nokuphendula izimfuno zabanikazi bebhuloho kanye nezakhiwo zokusebenza okuthuthukisiwe kokuqina. 'Ungqimba' ngalunye kunoma yiluphi uhlelo lokuvikela lunomsebenzi othize, futhi izinhlobo ezahlukene zisetshenziswa ngokulandelana okuthile kwe-primer elandelwa amajazi aphakathi / okwakha esitolo, futhi ekugcineni ijazi noma ijazi eliphezulu kungaba sesitolo noma esizeni. . I-Powder coating ibuye isetshenziselwe kakhulu ishubhu lensimbi eligoqiwe elibandayo elinopende omile oluyimpushana engxenyeni yensimbi ukuze kuvikelwe indawo. Ekusetshenzisweni okujwayelekile kopende omanzi ukunameka kulengiswa esiphathini esiwuketshezi esihwamuka siye emkhathini sishiya okokunamathela kuvikele indawo engaphezulu. Ingxenye embozwe ngempushana iyahlanzwa futhi impushana enamathelayo ishajwa ngogesi bese ifafazwa entweni ezogcotshwa. Khona-ke into ifakwa kuhhavini lapho izinhlayiya zokumboza impushana zincibilika khona zenze ifilimu eqhubekayo.
Ngaphandle kwento evikelayo, insimbi noma insimbi kulula ukukhiqiza ukugqwala -- inqubo eyaziwa ngokuthi ukugqwala. Ukuvimbela lokhu, abakhiqizi bamapayipi ensimbi bakha amapayipi ensimbi ngokuwamboza ngogqinsi lwezinki. Bacwilisa amapayipi etsheni lensimbi encibilikisiwe noma basebenzise amasu okufaka ugesi ngogesi. Ngaphambi kokuthumela la mapayipi, abakhiqizi bavame ukugcoba insimbi ngothayela ukuze bavimbele ukusabela kwe-zinc emkhathini. Lapho le ngxube kawoyela iguga, ukusabela kwe-zinc nomoya-mpilo kukhiqiza ifilimu emhlophe eshintsha umbala wensimbi usuke kompunga uye kompunga ongathandeki kangako. Lapho kushisa ukucwilisa ipayipi lensimbi idinga ukungeniswa kwamanye amazwe, lolu hlobo lwepayipi ngokuvamile luba nefilimu ye-passivator evikela insimbi ekugqwaleni endaweni enamanzi anosawoti njengoba insimbi ihamba izilwandle noma izilwandle ngemikhumbi yezimpahla.
Namuhla, inqubekelaphambili enkulu yenziwe ekusebenziseni ubuchwepheshe bokumboza ukuze kuvikeleke ukugqwala kwezakhiwo ezingasogwini, amathange angaphakathi kwemikhumbi ethwala uphethiloli, izindonga zemikhumbi, amapayipi angaphansi kwamanzi, njll. Kuye kwasungulwa izindlela ezintsha zokulungisa nokuvikela ukhonkolo nensimbi. izakhiwo emanzini asogwini nasogwini, njenge-all-polymer encapsulation technique ukuze kulungiswe futhi kuvikelwe izakhiwo endaweni ye-splash. Izidingo zesikhathi eside zesakhiwo noma zemishini zohlelo oluthile zingaqinisekiswa ngokuvikela ukugqwala, ngokusebenzisa ama-coatings noma inhlanganisela yokuvikelwa kwe-cathodic nama-coatings.
