Bokaholimo ba phala ea tšepe ea masenke bo boreleli haholo, ha ho sebelisoa substrate nako e telele ho tla boela ho be le mafome, e le ho etsa bonnete ba hore tšebeliso e tloaelehileng ea phala e entsoeng ka masenke, tsela ea ho penta e ka sireletsa tšepe hantle.Leha ho le joalo, bakeng sa phala galvanized tšepe, boholo ba pente bakeng sa galvanized holim'a sekhomaretsi ha e ntle, pente filimi le boreleli holim'a sekhomaretsi e futsanehile, le tšekamelo ea ho barbotage theoha bothata, kahoo galvanized tšepe phala le seo pente molemo?
ED1000 Epoxy Primer ke sekoaelo se khethehileng bakeng sa bokaholimo ba sekoti se nang le sekhomaretsi se setle le tšireletso e ntle bakeng sa liphaephe tsa masenke.Litšobotsi tse ka sehloohong tsa primer ke:
1. E loketse bakeng sa substrate ea galvanized, tšepe e sa hloekang, motsoako oa aluminium, poleiti ea aluminium le lisebelisoa tse ling tse boreleli, ho khomarela ka matla, ho khomarela filimi e tiileng;
2, kalafo ea holim'a substrate e bonolo, ha ho na sandblasting, ha ho na ho sila, tšebeliso ea solvent ho tlosa oli e ka hahuoa, ho boloka litšenyehelo tsa basebetsi le thepa;
3, khanyetso ea filimi ea letsoai e matla, ho fihlela lihora tse 1000, ho roala ho tiile, ho na le anticorrosive e babatsehang le ho hanyetsa mafome;
4. Pente ha e na litšepe tse boima, lead le chromium, e lumellana le litekanyetso tsa tlhahiso ea solvent ea EU, 'me e loketse ho romelloa kantle ho naha ea ho roala li-workpiece;
5, e ka tsamaisana le mefuta e fapaneng ea pente ea ho qetela, joalo ka pente ea fluorocarbon, pente ea polyurethane, pente ea epoxy, pente ea acrylic, jj.
Pipe ea tšepe e nang le galvanized e tlameha ho tlosoa pele ho penta holim'a oli, tšebeliso ea solvent ho hlakola bokaholimo ba substrate e ka tlosa oli ea oli ka katleho, ho qoba ho ama ho khomarela.Sebelisa ED1000 epoxy primer ka ho fafatsa, kopanya primer le pheko ka karo-karolelano ea 9: 1, eketsa epoxy thinner, hlohlelletsa ka ho lekana, 'me u apare botenya ba filimi e boletsoeng.Botenya ba filimi bo khothalelitsoeng ke 70μm.
ED1000 epoxy primer e na le mamarelo a matla le khanyetso e ntle ea kutu, empa boemo ba leholimo bo bobe, haholo bakeng sa ts'ebeliso ea kantle, e hloka ho tsamaisana le topcoat e hanyetsanang le boemo ba leholimo.Topcoat e sebelisoang hangata, joalo ka pente ea fluorocarbons, acrylic polyurethane topcoat le topcoat ea acrylic.Ka mor'a hore primer e omisitsoe, sebelisa topcoat 'me u fafatse botenya ba filimi e boletsoeng.Botenya ba filimi bo khothalelitsoeng ke 50-60μm.
Pipe e entsoeng ka galvanized e nang le primer le ho qeta ho roala, filimi ea ho roala e na le ho khomarela hantle, ho hanyetsa kutu, ho khabisa le ho hanyetsa boemo ba leholimo, ka boholo ba tikoloho e ka ba tšireletso e ntle haholo.
