Ngokukhula kancane kancane kokusetshenziswa kwezinsimbi ezinamekwe ngemibala embonini yezokwakha, ukunaka kwabantu kuyaqhubeka kukhuphuka izinsimbi zensimbi ezinamekwe ngemibala.
Ngokwezibalo ezingaphelele: Ngo-2016, ukusetshenziswa kwasekhaya kwe-China kwamapuleti ensimbi apendwe ngaphambili kwakungamathani ayizigidi ezingu-5.8. Ngakho-ke, ipuleti lensimbi elipendwe ngaphambili likhiqizwa kanjani?
Amapuleti ensimbi afakwe umbala(aziwa nangokuthi amapuleti ensimbi anama-organic coated kanye namapuleti ensimbi ahlanganiswe ngaphambili) aqanjwe ngamagama ensimbi eyisisekelo (okubizwa ngokuthi ama-substrates) ahlanganiswe ngemibala ehlukahlukene.
Ishidi lensimbi elifakwe umbala liwumkhiqizo onomjikelezo omude wokukhiqiza.Ukusuka ekugingqikeni okushisayo kuye ekugoqeni okubandayo, inogqinsi oluthize, ububanzi kanye nephethini, bese ingena ku-annealing, galvanizing kanye nokufakwa kombala ukwenza umbala ogqamile.ishidi elifakwe umbala.Izinqubo zokukhiqiza eziyinhloko zeyunithi yokuhlanganisa umbala zihlanganisa:Inqubo yokwelashwa, inqubo yokugcoba, inqubo yokubhaka
1. Inqubo yokwelashwa kwangaphambili
Ngokuyinhloko inqubo yokukhipha ukungcola namafutha ahlanganiswe phezulu ngemva kokuba i-substrate ihlanzwa;kanye nokwelashwa kwenhlanganisela ye-oxidation kanye ne-passivation ukwenza ifilimu yokwelashwa kwangaphambili.Ifilimu ye-pretreatment iyindlela ephumelelayo yokuthuthukisa amandla okubopha phakathi kwe-substrate ne-coating.
2. Inqubo yokuhlanganisa
Njengamanje, inqubo yokugqoka evame ukusetshenziswa kakhulu yamayunithi okugqoka umbala ezitshalweni ezinkulu zensimbi i-roller coating.I-Roll coating iwukuletha upende epanini likapende ku-roller yokugqoka ngokusebenzisa i-roller yebhande, futhi kwakheka ukuqina okuthile kwefilimu emanzi ku-roller yokugqoka., Bese udlulisela lolu ungqimba lwefilimu olumanzi endleleni yokumboza yendawo engaphansi. Ngokulungisa igebe le-roller, ingcindezi kanye nesivinini se-roller, ukushuba kwe-coating kungandiswa noma kwehliswe phakathi kwebanga elithile; Kungenziwa ngopende ohlangothini olulodwa noma nhlangothi zombili ngesikhathi esisodwa.Le ndlela iyashesha futhi inokukhiqiza okuphezulu.
3. Inqubo yokubhaka
Inqubo yokubhaka ikakhulukazi iphathelene nokuphulukiswa kwe-coating ebusweni bepuleti lensimbi, okusho ukuthi ukumboza kudlula i-polycondensation yamakhemikhali, i-polyaddition, i-crosslinking nokunye ukusabela ngaphansi kwezinga lokushisa elithile nezinye izimo ngokusebenzisa impahla eyinhloko yokwakha ifilimu, insiza. izinto zokwakha ifilimu kanye ne-ejenti yokwelapha.Inqubo yokushintsha isuka ewuketshezi iye eqinile.Inqubo yokwelapha kanye nokubhaka ngokuvamile ihlanganisa ukubhaka okunamathelayo, ukubhaka okucolisekileyo kanye nohlelo oluhambisanayo lokushiswa kwegesi eyimfucuza.
4. Ukucutshungulwa okulandelayo kweinsimbi ependwe ngaphambiliishidi
Kubandakanya ukufaka i-embossing, ukuphrinta, i-laminating nezinye izindlela zokwelapha, i-waxing noma ifilimu yokuzivikela nayo ingangezwa, engakhulisi nje umphumela wokulwa nokugqwala wepuleti elihlanganiswe ngombala, kodwa futhi ivikela ipuleti elinemibala emihumeni ngesikhathi sokuphatha noma ukucubungula. .
