Ngokunyuka ngokuthe ngcembe kokusetyenziswa kwamaphepha entsimbi agqunywe ngombala kushishino lokwakha, ingqalelo yabantu kumaphepha entsimbi agqunywe ngombala iyaqhubeka ikhula.
Ngokwezibalo ezingaphelelanga: Ngo-2016, ukusetyenziswa kwekhaya laseChina kwiiplate zentsimbi ezipeyintiweyo zangaphambili zazimalunga neetoni ezizigidi ezi-5.8. Ngoko ke, iveliswa njani ngokuchanekileyo ipleyiti yensimbi eyenziwe ngaphambili?
Iipleyiti zentsimbi ezifakwe ngombala(ekwaziwa ngokuba ziipleyiti zentsimbi eziqatyiweyo kunye neepleyiti zentsimbi eziqatywe ngaphambili) zithiywe ngegama lesiseko seepleyiti zentsimbi (ekubhekiselwa kuzo njenge substrates) eziqatywe ngemibala eyahlukeneyo.
Ishiti lentsimbi elifakwe ngombala liyimveliso enomjikelezo omde wemveliso.Ukusuka ekuqengqelekeni okushushu ukuya ekuqengqelekeni okubandayo, inobungqingqwa obuthile, ububanzi kunye nepateni, kwaye emva koko ingene kwi-annealing, igalvanizing kunye nokufakwa kombala ukwenza umbala onemibala.iphepha elifakwe umbala.Iinkqubo eziphambili zemveliso yeyunithi yokugqoka umbala ibandakanya: Inkqubo yonyango kwangaphambili, inkqubo yokugqoka, inkqubo yokubhaka
1. Inkqubo yonyango lwangaphambili
Ikakhulu yinkqubo yokususa ukungcola kunye namafutha aqhotyoshelwe kumphezulu emva kokuba i-substrate ihlanjululwe;kunye nokwenza unyango oludityanisiweyo lwe-oxidation kunye ne-passivation ukwenza ifilimu yonyango lwangaphambili.Ifilimu yangaphambili yindlela esebenzayo yokuphucula amandla okudibanisa phakathi kwe-substrate kunye nokwaleka.
2. Inkqubo yokwaleka
Okwangoku, eyona nkqubo isetyenziswa ngokuqhelekileyo yokugquma kwiiyunithi zokugquma umbala kwizityalo ezinkulu zentsimbi yi-roller coating.Ukuqengqeleka kokuqengqeleka kukuzisa ipeyinti kwipeyinti yepeyinti kwi-roller yokwambathisa ngebhanti, kwaye ubungakanani obuthile befilimu emanzi bubunjwa kwi-roller yokwambathisa., Kwaye emva koko udlulisele olu luhlu lwefilimu emanzi kwindlela yokugqoka ye-substrate surface.Ngokulungelelanisa i-gap ye-roller, uxinzelelo kunye nesantya se-roller, ubukhulu bokutya bunokwandiswa okanye bunciphe phakathi koluhlu oluthile; Inokupeyintwa kwelinye icala okanye macala omabini ngaxeshanye.Le ndlela ikhawuleza kwaye inemveliso ephezulu yokusebenza.
3, Inkqubo yokubhaka
Inkqubo yokubhaka ubukhulu becala ijongene nokunyangwa kokugquma kumphezulu wepleyiti yentsimbi, okuthetha ukuba ukwambathisa kungena ikhemikhali i-polycondensation, i-polyadition, i-crosslinking kunye nezinye iimpendulo phantsi kobushushu obuthile kunye nezinye iimeko ngokusetyenziswa kweyona nto iphambili yokwenza ifilimu, encedisayo. imathiriyeli yokwenza ifilim kunye nearhente yokunyanga.Inkqubo yokutshintsha ukusuka kulwelo ukuya kwi-solid.Inkqubo yokwaleka kunye neyokubhaka ngokubanzi ibandakanya ukubhaka okusisiseko, ukubhaka okutyayo okucolekileyo kunye nenkqubo yokutshisa inkunkuma yenkunkuma.
4. Ukusetyenzwa okulandelayo kweintsimbi epeyintwe ngaphambiliiphepha
Kubandakanya i-embossing, ukuprinta, i-laminating kunye nezinye iindlela zonyango, i-waxing okanye ifilimu ekhuselayo inokudibaniswa nayo, engagcini nje ukwandisa umphumo wokuchasana ne-corrosion ye-plate ehlanganiswe nombala, kodwa ikhusela ipleyiti enombala kwimikrwelo ngexesha lokuphatha okanye ukusetyenzwa. .
