Yeyiphi ipeyinti esetyenziswa ngumbhobho wentsimbi?

Umphezulu wombhobho wentsimbi ugudileyo kakhulu, ekusebenziseni ixesha elide le-substrate kuya kwenzeka nomhlwa, ukwenzela ukuba kuqinisekiswe ukusetyenziswa okuqhelekileyo kombhobho we-galvanized, indlela yokudweba inokukhusela ngcono isinyithi.Nangona kunjalo, kumbhobho wentsimbi owenziwe ngesinyithi, uninzi lwepeyinti yokuncamathela phezu komhlaba ayilungile, ifilim yepeyinti kunye nokuncamathela okugudileyo komphezulu kubi, kuqheleke ukuyigquma ingxaki, ngoko ke umbhobho wentsimbi enamathelwe ngeyiphi ipeyinti engcono?

I-ED1000 Epoxy Primer yinto ekhethekileyo yokwaleka kumphezulu we-galvanized substrate kunye nokunamathela okugqwesileyo kunye nokhuseleko olulungileyo lwemibhobho yegalvanized.Iimpawu eziphambili zeprimer zezi:

1. Ifanelekile kwi-substrate ye-galvanized, insimbi engenasici, i-aluminium alloy, i-aluminium plate kunye nezinye izinyithi ezigudileyo, i-adhesion eyomeleleyo, ifilimu yokubambelela ngokuqinileyo;

I-2, unyango lwe-substrate surface lulula, alukho i-sandblasting, akukho kugaya, ukusetyenziswa kwe-solvent ukususa ioli kunokwakhiwa, gcina iindleko zabasebenzi kunye nezinto eziphathekayo;

I-3, ifilimu yokumelana nokutshiza ityuwa yomelele, ukuya kuthi ga kwiiyure ze-1000, i-coating is intact, kunye ne-anticorrosive egqwesileyo kunye nokuxhathisa umhlwa;

4. Ipeyinti ayinayo isinyithi esinzima, i-lead kunye ne-chromium, ihambelana nemigangatho yokukhutshwa kwe-solvent ye-EU, kwaye ifanelekile ukuthunyelwa ngaphandle kwe-workpiece coating;

I-5, inokudityaniswa neentlobo ezahlukeneyo zepeyinti yokugqiba, njengepeyinti ye-fluorocarbon, ipeyinti ye-polyurethane, ipeyinti ye-epoxy, ipeyinti ye-acrylic, njl.

Umbhobho wensimbi owenziwe ngesinyithi kufuneka ususwe ngaphambi kokupenda i-oyile yomhlaba, ukusetyenziswa kwe-solvent ukucima ubuso be-substrate kunokususa ngokufanelekileyo ioli yeoli, ukuphepha ukuchaphazela ukunamathela.Faka i-ED1000 epoxy primer ngesitshizi, i-primer yokuxuba kunye ne-ejenti yokunyanga kumlinganiselo we-9: 1, yongeza i-epoxy thinner, ugxobhoze ngokulinganayo, kunye nedyasi kubukhulu befilimu obuchaziweyo.Ubukhulu befilimu obucetyiswayo bungama-70μm.

I-ED1000 epoxy primer inoncanyelo olomeleleyo kunye nokumelana nokugqwesa okugqwesileyo, kodwa ukumelana nemozulu embi, ngakumbi kusetyenziso lwangaphandle, kufuneka ihambelane netopcoat ekwaziyo ukumelana nemozulu.Itopcoat esetyenziswa ngokuqhelekileyo, njengepeyinti yefluorocarbons, i-acrylic polyurethane topcoat kunye ne-acrylic topcoat.Emva kokuba i-primer isomile, sebenzisa i-topcoat kunye ne-spray kubukhulu befilimu obuchaziweyo.Ubunzima befilimu obucetyiswayo bungama-50-60μm.

Umbhobho owenziwe ngegalvanized kunye ne-primer kunye nokugqiba ukutyabeka, ifilimu yokugqoka inokubambelela kakuhle, ukuxhathisa ukubola, ukuhlobisa kunye nokumelana nemozulu, kwiindawo ezininzi zokusingqongileyo kunokukhusela kakuhle kakhulu.
