Ikhoyili efakwe umbala yenziwe ngengubo ephezulu, i-primer, i-coating, i-substrate kunye nepeyinti yangasemva.
Gqibezela ipeyinti:khusela ilanga, ukukhusela umonakalo we-ultraviolet kwisambatho;Xa isiphelo sifikelela kubukhulu obuchaziweyo, sinokwenza ifilimu yokukhusela exineneyo, ukunciphisa ukunyanzeliswa kwamanzi kunye ne-oxygen.
Isiqalo:kunenzuzo ukuqinisa ukunamathela kwe-substrate, ukwenzela ukuba ukuchithwa kwepeyinti akulula ukuba kwenzeke emva kokuba ifilimu ifakwe emanzini, kwaye iya kuphucula ukuxhathisa kwe-corrosion, kuba i-primer iqulethe i-corrosion inhibitor pigments, njenge-chromate pigments, ukwenzela ukuba i-anode igqitywe kwaye ukuchasana kwe-corrosion kuphuculwe.
Ukwaleka:ngokubanzi igalvanized okanye i-aluminiyam i-zinc plating, le nxalenye yobomi benkonzo yemveliso ineempembelelo ezinkulu, okukhona ukugquma, kungcono ukuxhathisa umhlwa.
Indawo engaphantsi:ngokubanzi kubanda ipleyiti esongwayo, amandla ezahlukeneyo imisela iimpawu mechanical ipleyiti eqatywe umbala unokuthwala.
Ipeyinti yangasemva:umsebenzi kukuthintela ukubola kwepleyiti yensimbi ukusuka ngaphakathi, ngokubanzi imigangatho emibini yesakhiwo (2/1M okanye 2/2, i-primer + ipeyinti yangasemva), ukuba umva ufuna ukudityaniswa, kuyacetyiswa ukuba kusetyenziswe isakhiwo esisodwa. (2/1).
Inkqubo yokuthotywa kwekhoyili yentsimbi eqatywe ngombala:
Ukugquma ukugquma, ukugquma kombala, ukutyabeka ngomgubo, ukutyabeka okuqhekezayo, mhlophe/bomvu — – — – — kumgca wokusika uchuba umhlwa – usike – indawo yokwaleka — – — – — indawo enkulu yomhlwa, intsimbi yendawo ebomvu – ipleyiti. – ukusilela kwepleyiti yokugrumba.
Inkqubo yokungaphumeleli kwepleyiti yensimbi enombala iboniswe kumzobo ongentla.Ukungaphumeleli kokwambathisa, ukungaphumeleli kokugquma kunye nokugqobhozwa kwepleyiti yentsimbi ziinkqubo eziphambili zokubola.Ke ngoko, ukonyusa ubukhulu bokugquma kunye nokusebenzisa imozulu kunye ne-corrosion resistant coating zezona ndlela zisebenzayo zokuthintela ukungaphumeleli kokutya kwepleyiti yentsimbi enombala.
