Ipeyinti elwa nomhlwa

Ipeyinti yokulwa nomhlwa luhlobo oluthile lwento edlala indima yokulwa nomhlwa, ithintela ukubola kwesinyithi kwaye iphucula isiphumo sokukhusela sefilimu yepeyinti kumphezulu wesinyithi. Indima yepeyinti yokulwa nomhlwa inokwahlulwahlulwa ibe ziindidi ezimbini: ipeyinti yokulwa nomhlwa ngokwasemzimbeni kunye nepeyinti yokulwa nomhlwa ngamakhemikhali, apho ipeyinti yokulwa nomhlwa ngamakhemikhali inokwahlulwahlulwa ibe kukuthintela ukubola kunye ne-electrochemical action type two. Izinto ezidlala indima yokuthintela umhlwa ziquka umgubo obomvu opinki, umgubo obomvu wesinyithi, umgubo we-titanium yesinyithi odibeneyo, umgubo we-aluminium tripolyphosphate zinc njalo njalo. Okwangoku, ipeyinti yokulwa nomhlwa isetyenziswa kakhulu kwiingubo zokulwa nomhlwa, kwaye ixabiso leengubo zokulwa nomhlwa lifikelela kwi-6%-8.5%.

Yintoni umahluko phakathi kwepeyinti echasene nomhlwa kunye nepeyinti?

Ipeyinti yokulwa nomhlwa luhlobo lwepeyinti enokukhusela iindawo zesinyithi ekungcoleni kwamakhemikhali okanye kwe-electrochemical emoyeni, emanzini olwandle, njl. Ipeyinti yokulwa nomhlwa ebonakalayo neyekhemikhali, efana nentsimbi ebomvu, umgubo we-aluminiyam, ipeyinti yokulwa nomhlwa yegrafiti, i-red lead, ipeyinti ye-zinc etyheli yokulwa nomhlwa njalo njalo.

Ipeyinti yingubo yomxube weekhemikhali egubungela ngokuqinileyo umphezulu wezinto, ikhusele, ihombise, iphawule kunye nezinye iinjongo ezikhethekileyo, kwaye yenze ifilimu eqinileyo enamathela ngokuqinileyo kumphezulu wezinto kwaye inamandla athile kunye nokuqhubekeka.

1. Imisebenzi eyahlukeneyo:

Ipeyinti elwa nomhlwa ineempawu zokulwa nomhlwa kunye nokulwa nomhlwa, ifilimu iqinile, isebenza kakuhle kakhulu, kwaye ubunzima buphezulu kunobo bepeyinti eqhelekileyo. Ipeyinti eqhelekileyo ayinawo umsebenzi wokulwa nomhlwa, kuba izinto zepeyinti eqhelekileyo yi-alkyd resin, ngenxa ye-oxidation kunye nokomisa, ubunzima obuphantsi, kunye nomsantsa wenqanaba lokunamathela.

2. Ubomi benkonzo obahlukeneyo:

Ipeyinti elwa nomhlwa ingasetyenziswa iminyaka emi-5-8 xa ifaniswa. Ipeyinti eqhelekileyo idla ngokusetyenziswa ngaphandle kangangeminyaka emi-3. Emva kweminyaka emibini okanye emithathu, kulula ukuyiwa, iphele kwaye ibe ngumgubo.

3. Iintlobo ezahlukeneyo:

Ipeyinti echasene nomhlwa: ipeyinti echasene nomhlwa ye-phenolic, ipeyinti echasene nomhlwa ye-alkyd (intsimbi ebomvu, engwevu, i-red lead), ipeyinti echasene nomhlwa yerabha ene-chlorine, ipeyinti echasene nomhlwa ye-epoxy (ipeyinti echasene nomhlwa ye-zinc phosphate, ipeyinti echasene nomhlwa ye-red lead, ipeyinti echasene nomhlwa etyebileyo ye-zinc, ipeyinti echasene nomhlwa yentsimbi ebomvu), njl.

Ipeyinti: Iindidi ezityebileyo zepeyinti, ipeyinti yokulwa nomhlwa nayo iluhlobo lwepeyinti, ukongeza kwipeyinti ikwabandakanya ipeyinti yomthi, ipeyinti yomgangatho, ipeyinti yodonga lwangaphandle, ipeyinti yamatye, ipeyinti enemibala emininzi, ipeyinti ye-aluminium alloy, ipeyinti engatshiyo, ipeyinti ye-latex njalo njalo.

Imiyalelo esibhozo yophuhliso lwexesha elizayo lwepeyinti yokulwa nomhlwa

Okokuqala, uphuhliso lwe-primer elwa nomhlwa esekwe emanzini kunye nepeyinti ephezulu yezakhiwo zentsimbi.

I-primer elwa nomhlwa esekwe emanzini kufuneka isombulule ingxaki ye-substrate "flash rust" kunye nokumelana kwamanzi okungekho semgangathweni, kwaye ukunyuka kwezinye ii-emulsions ezintsha ezingenayo i-emulsifier kuye kwaphucula ngokusisiseko isihloko sayo sokumelana kwamanzi okungekho semgangathweni, kwaye ikamva kufuneka ligxile ekusombululeni iingxaki zomsebenzi wokwakha kunye nomsebenzi wokusetyenziswa. Njenge-topcoat, ikakhulu kukuphucula ukuhombisa kwayo kunye nokuqina kwayo phantsi kwemeko yokuqinisekisa umsebenzi wokukhusela.

Okwesibini kukuphuhlisa uthotho lwepeyinti eqinileyo ephezulu kunye nepeyinti yokulwa nomhlwa engenazinyibilikisi.

Ukugrumba, amaqonga aselwandle kunye neeprojekthi ezinkulu zokulwa nomhlwa kumsebenzi wokulwa nomhlwa ohlala ixesha elide weemfuno zokugquma zingxamisekile kakhulu, imakethi yangoku ngokuyintloko ngamashishini angaphandle kunye neemveliso ezingenisiweyo ezihlala abantu. Iimveliso zaseTshayina ikakhulu zikwinqanaba lobugcisa, amandla oqoqosho, inkqubo yokuqinisekisa umgangatho kunye nodumo lwemveliso kunye neminye imingcele yamandla apheleleyo namazwe angaphandle, kunzima ukungena kwimarike. Ngenxa yesi sizathu, okokuqala, kufuneka kwenziwe imizamo kuphuhliso lobuchwephesha, ngakumbi uphuhliso lweprimer yepigment engenalo i-lead kunye ne-chromium-free anti-rust, oko kukuthi, ngokusekelwe kwiprimer ye-zinc phosphate kunye ne-aluminium tripolyphosphate anti-rust.

Okwesithathu kukuphuhlisa i-primer etyebileyo emanzini enezinc.

I-primer etyebileyo kwi-zinc engaphiliyo kunye ne-primer etyebileyo kwi-zinc engaphiliyo esekwe emanzini zezinye zee-primer ezisebenza ixesha elide, kodwa zizinto ezinyibilikisayo. I-primer etyebileyo kwi-zinc engaphiliyo esekwe emanzini ene-potassium silicate ephezulu njengezinto ezisisiseko yi-coating esebenzayo yokulwa nomhlwa evavanyiweyo ngokusebenza kwaye inamandla ophuhliso.

Okwesine kukuphuhliswa kwe-heat exchanger ephilisa ubushushu ne-anti-rust coating.

Izitshintshi zobushushu zifuna izinto zokugquma ezichasene nomhlwa ezinokumelana nobushushu obuphezulu kunye nokuqhuba kobushushu, kwaye i-epoxy amino coating esetyenziswayo ngoku kufuneka icocwe kwi-120 ° C kwaye ifuna izinto ezininzi zokugquma, ezingenakusetyenziswa kwizixhobo ezinkulu.

Okwesihlanu kukwenza ulusu olunokulungiswa kubushushu begumbi kwaye kube lula ukulusebenzisa.

Ingongoma ephambili kukufumana ibhalansi engcono phakathi komsebenzi wokuthintela umhlwa, umsebenzi wokudlulisa ubushushu kunye nomsebenzi wokwakha wengubo.

Okwesithandathu kukuphuhliswa kwengubo yokulwa nomhlwa egqunywe zii-flake.

I-Mica iron oxide (MIO) inokumelana okuhle kakhulu ne-dielectric, ukumelana nokwaluphala emoyeni kunye nomsebenzi wokuyivimba, kwaye isetyenziswa kakhulu njengepeyinti yokuqala kunye nepeyinti ephezulu eNtshona Yurophu.

Okwesixhenxe, uphuhliso lwerabha ekhloriniweyo yezinto ezithatha indawo yerabha ezilwa nomhlwa.

Ngenxa yokuba irabha enekhlorini iyinxalenye enye, ulwakhiwo lwayo lulula, ukumelana namanzi, ukumelana neoyile, ukumelana nokwaluphala emoyeni kugqwesile, kusetyenziswa kakhulu ekwakheni iinqanawa, ukuthintela umhlwa kwimizi-mveliso nakwezinye iindawo, kukho imakethi ebanzi eTshayina. Nangona kunjalo, ngenxa yokuba imveliso yerabha enekhlorini isebenzisa i-CC1 njengesinyibilikisi, umaleko we-ozone uyatshatyalaliswa.

Eyesibhozo kukuphuhliswa kwezinto zokuthintela umhlwa eziguqulweyo kwizinto eziphilayo.

Kwiminyaka yakutshanje, ukusetyenziswa kwekhonkrithi ye-organic emulsion kutshintshe amandla ayo, ukumelana okuphakathi, esetyenziswa kakhulu ekugqumeni umgangatho wemizi-mveliso. Phakathi kwazo, i-epoxy water emulsion (okanye i-epoxy esekelwe kwi-solvent) iphuhlisa eyona ikhawulezayo, ebizwa ngokuba yi-polymer cement.
