Ka indasteri ea tlhahiso ea indasteri ea ho fafatsa, mefuta ea lihlahisoa tsa pampiri e pentiloeng e batla e arotsoe ka thepa ea polasetiki le ea tšepe.E le hore u fumane hantle sebaka se fafalitsoeng hantle ho rarolla phello ea sebele, ho roala pente ho tlameha ho khomarela ka thata ho lakane.Hangata ka mor'a ho penta ka ho khetheha, boteng ba bothata ba ho ebola ha pente e ntse e le bothata bo batlang bo se na tšepo.

Pompo ea oli ea polasetiki le tharollo e fokolang ea sekhomaretsi:

Ts'ebetso ea ho fafatsa ka holim'a maqephe a polasetiki e kenyelletsa liindasteri tse ngata, joalo ka lisebelisoa tsa elektroniki, theknoloji ea dijithale, litlhoko tsa letsatsi le letsatsi, lintho tsa ho bapala tse nyane, joalo-joalo, empa mathata a ts'oanang a kang ho khomarela hampe le peeling ea pente hangata a etsahala.Ka indasteri ea tlhahiso ea pompo ea oli le ho e lokisa, tharollo e utloahalang ke ho ntlafatsa ho khomarela ho ea ka primer ea moetsi oa adhesion treatment adhesion.Li-substrates tse fapaneng li tlameha ho hlahlojoa bakeng sa thepa le meaho e fapaneng, 'me li-primers tse tsamaellanang le tsona li fapane, joalo ka PP primer bakeng sa ho fafatsa ka polasetiki ea PP, moemeli oa kalafo oa polyester bakeng sa ho fafatsa polasetiki ea polyester, jj.

Litharollo tsa ho khomarela hampe ha tšepe ea aluminium alloy substrate fafatsa:

Har'a li-substrates tsa tšepe, lisebelisoa tsa alloy tsa zinki, li-profiles tsa aluminium alloy, lipoleiti tsa tšepe tse sa hloekang le li-substrates tse ling li fafatsoa ho feta holim'a metsi, hobane karolo e ka holimo ea aluminium alloy substrates ka kakaretso e na le reducibility le holim'a poleiti ea tšepe e boreleli, e bakang ho se kgone ho penta ho khomarela ka tsela e utloahalang., Ha tlhahlobo ea ho khomarela e etsoa, ​​bothata ba ho penta pente bo bonolo haholo ho etsahala.Ho ea ka primer ea lisebelisoa tsa tšepe e entsoeng ke moetsi oa moemeli oa phekolo ea ho khomarela, e hlahisa lera le ka hare le kopanyang substrate le pente, e thusang ho ntlafatsa ho khomarela, ho ntlafatsa ho khomarela pente, le ho sebetsana le pente ea peeling.

Ha ho etsoa pente e khethehileng ea spray, ho boetse ho na le mefuta e fapaneng ea tharollo e sebelisoang hangata ho ntlafatsa ho khomarela, joalo ka phekolo ea corona, litharollo tsa ho sila le ho bentša, litharollo tsa lelakabe le litharollo tse ling tsa lik'hemik'hale tse phelang.Moemeli oa phekolo ea mofuta oa primer o entsoeng ke moetsi oa moemeli oa phekolo o thata ho laola ts'ebetsong ea sebele, 'me phello ea sebele ea ho ntlafatsa ho khomarela ha e bohlokoa ebile ha e tsitsa.Moemeli oa phekolo ea mofuta oa primer o fafatsoa holim'a lakane ho latela mokhoa oa ho fafatsa, ebe mekhoa e meng ea theknoloji e ka etsoa.

Ka boleng bo botle, theko e utloahalang le tšebeletso e phethahetseng ea ka mor'a thekiso, Philkas e hapile kamohelo ea bahlahisi ba bangata ba oli ho ea metsing.Ha pente ea setso e thehiloeng ho solvent e ntse e nyamela butle-butle mahlong a rona, monko o hlabang oa pente o ke ke oa ama bophelo ba rona.Melemo ea pente e entsoeng ka metsi e bonahala ka ho hlaka nakong ena eo batho bohle ba elang hloko ho sireletsa tikoloho.Pente e thehiloeng metsing ea Fairkas e sebelisa metsi e le ntho e hlapollang, e se nang chefo le tikoloho, e nang le ts'ebetso e ntle haholo, e thibelang kutu e matla le ho hanyetsa boemo ba leholimo, le kaho e bonolo.
