Pendi ine zinc rich epoxy primer inowanzoshandiswa mumaindasitiri, ine zvikamu zviviri zvependi, kusanganisira kugadzira pendi uye mushonga wekupisa. Upfu hwezinc hunoita basa rakakosha pakushanda zvakanaka kweprimer ine epoxy zinc rich. Saka, ingani yakakodzera huwandu hwezinc, uye ndeapi mhedzisiro yakasiyana yehuwandu hwezinc hwakasiyana?
Kuwanda kwe zinc mu epoxy zinc primer kwakasiyana, zvichienderana nezvinodiwa nekugadzirwa kwayo kuti pave nekugadzirisa kwakakodzera, kusiyana kwe zinc, mazinga akasiyana ekudzivirira ngura. Kuwanda kwehuwandu, simba rekudzivirira ngura, kudzikira kwehuwandu, kushanda kwengura kwakaderera. Zvichitevera mwero wepasi rose weindasitiri, huwandu hwe zinc mu epoxy primer ine zinc yakawanda, hunosvika 60%.
Kunze kwekudiwa kwehuwandu hwezinc, ukobvu hwefirimu hwakakoshawo zvikuru. Sekureva kweISO12944-2007, ukobvu hwefirimu rakaoma hunosvika 60μm seprimer inodzivirira ngura, uye 25μm seprimer yechitoro.
Pendi iyi ichaita hwema hwakaipa hwenzvimbo yemukati, kuitira kuti mhepo yemukati idzoke nekukurumidza sezvinobvira pakanaka, ndapota ita kuti mhepo ipfuure kamwe chete kusvika kaviri pazuva, nguva imwe neimwe maminetsi gumi kusvika makumi maviri ekufema kuti mweya mutsva uwedzere.
