I-primer ye-epoxy etyebileyo yi-zinc rich yipeyinti eqhelekileyo esetyenziswa kwimizi-mveliso, ineenxalenye ezimbini zepeyinti, kuquka ukwenziwa kwepeyinti kunye ne-agent yokuphilisa. Umgubo we-zinc udlala indima ebalulekileyo ekusebenzeni kakuhle kwe-primer ye-epoxy zinc rich. Ngoko ke, Ingakanani ifanelekileyo kwinani le-zinc, kwaye zithini iziphumo ezahlukeneyo zomxholo we-zinc owahlukileyo?
Umxholo we-zinc kwi-primer etyebileyo ye-epoxy zinc wahlukile, ngokwemfuno yolwakhiwo lokwenza uhlengahlengiso olufanelekileyo, umxholo we-zinc owahlukileyo, amanqanaba ahlukeneyo esiphumo sokumelana nokugqwala. Okukhona umxholo uphezulu, kokukhona unamandla okuxhathisa ukugqwala, kokukhona umxholo uphantsi, ukusebenza kokugqwala kuphantsi. Ukulandela umgangatho wezoshishino wamazwe ngamazwe, umxholo we-zinc kwi-primer etyebileyo ye-zinc zinc, ubuncinci yi-60%.
Ngaphandle kwemfuneko yomxholo we-zinc, ubukhulu befilimu nabo bubaluleke kakhulu. Ngokwe-ISO12944-2007, ubukhulu befilimu eyomileyo yi-60μm njenge-primer echasene nokubola, kunye ne-25μm njenge-primer yevenkile.
Ipeyinti iya kwenza ivumba elibi kwindawo engaphakathi, ukuze umoya ongaphakathi ubuyele kwimeko entle ngokukhawuleza, nceda wenze umoya udlule ka-1-2 ngemini, rhoqo emva kwemizuzu eli-10-20 ukuze ufumane umoya omtsha ngakumbi nangakumbi.
