Ingaba ipleyiti yentsimbi enombala ifikelela njani kwi-anti-corrosion? Ipleyiti yentsimbi egqunywe ngombala, ekwabizwa ngokuba yipleyiti yentsimbi egqunywe ngombala, sisiphumo sesenzo esidityanisiweyo sokutyabeka, umaleko wonyango wangaphambili, iprimer, kunye netopcoat. Siyibiza ngokuba "zine kwinkqubo enye yokunqanda ukubola kwepleyiti yentsimbi egqunywe ngombala". Ibhodi yethu egqunywe ngombala yenziwe ngeempawu ezahlukeneyo zokugquma kwaye yagqunywa ngokweendidi ezi-5 kunye neenkqubo ezingama-48, ezineempawu ezibalaseleyo zokuchasa umhlwa.
Ukumelana nokubola kunye nokuxhathisa okuhlala ixesha elide.
Sifikelela njani kwi-anti-corrosion yeepleyiti zentsimbi ezigqunywe ngombala? Ipleyiti yentsimbi egqunywe ngombala, ekwabizwa ngokuba yipleyiti yentsimbi egqunywe ngombala, sisiphumo sesenzo esidityanisiweyo sokutyabeka, umaleko wonyango wangaphambili, iprimer, kunye netopcoat. Siyibiza ngokuba "zine kwinkqubo enye yokunqanda ukubola kwepleyiti yentsimbi egqunywe ngombala".
Ukugquma kwepleyiti yentsimbi yombala kudlala indima echasene nokubola kwedini. Ukubeka nje, yandisa ubomi benkonzo yentsimbi yentsimbi ngokuqhubeka isitya isambatho sayo. Ngokuqinisekileyo, uhlobo, umgangatho, kunye nobukhulu bengubo zizinto eziphambili kubude bexesha lokusetyenziswa kokutya. Iipleyiti zethu zentsimbi ezigqunywe ngombala ikakhulu zisebenzisa i-galvanized, i-aluminium zinc, i-aluminium galvanized magnesium kunye nezinye iipleyiti zentsimbi ezigqunywe kwizityalo ezinkulu zentsimbi zasekhaya, ezinamandla aphezulu kunye nokumelana nokugqwesa okungcono.
Makhe sithethe ngomaleko wangaphambili wonyango kwakhona. Le yinxalenye ebalulekileyo ye-anti-corrosion yamacwecwe ensimbi yombala, ehlala ingahoywa. Umaleko wonyango wangaphambili, okwaziwa ngokuba yi-passivation layer, ifuna ukusetyenziswa kwezisombululo ze-passivation ezifana ne-phosphate okanye i-chromate ukudlula umphezulu we-substrate ngaphambi kokugquma kombala. Oku akugcini nje ukwandisa ukunamathela kwengubo, kodwa kudlala indima ekuchaseni ukubola. Uphando lubonise ukuba kuvavanyo olungathathi hlangothi lokuxhathisa isitshizi setyuwa kwiipleyiti ezigqunywe ngombala, izinga legalelo lomgangatho wangaphambi konyango lifikelela ngaphezulu kwama-60%.
Makhe sithethe nge-primer kwakhona. Ngakolunye uhlangothi, i-primer idlala indima ekunyuseni ukunamathela kwengubo. Emva kokuba ifilimu yepeyinti ifikeleleke, ayiyi kuqhawula kwi-coating, ithintele i-blistering kunye ne-detachment of the coating. Kwelinye icala, ngenxa yobukho beepigments ezicothayo ezifana neechromates kwiprimer, inokudlula i-anode kwaye iphucule ukuxhathisa kokubola kwengubo.
Ekugqibeleni, makhe sithethe nge-topcoat. Ukongeza kwi-aesthetics, i-topcoat ikakhulu isebenza ukuvimba ukukhanya kwelanga kunye nokuthintela umonakalo we-UV kwisambatho. Emva kokuba i-topcoat ifikelele kubukhulu obuthile, inokunciphisa ukuveliswa kwee-micropores, ngaloo ndlela ikhusela ukungena kwemithombo yeendaba ezonakalisayo, ukunciphisa amanzi kunye ne-oksijini yokungena kwi-coating, kunye nokuthintela ukubola kwengubo. Ukuchasana kwe-UV kunye nobuninzi beengubo ezahlukeneyo ziyahluka, kwaye kuhlobo olufanayo lokugquma, ubukhulu befilimu yepeyinti yinto ephambili echaphazela ukubola. Iibhodi zethu ezigqunywe ngombala zenziwe ngokukhetha iintlobo ezahlukeneyo zokwaleka eziye zanyangwa kumaqondo obushushu aphezulu, nto leyo ekhokelela ekuxhathiseni umhlwa okuphezulu kunye nokusebenza ixesha elide lokungafihli.
