Iyo Iyo primer inowanzoshandiswa kudzivirira ngura uye kudzivirira ngura yesimbi kudzivirira ngura yesimbi, iyo primer ine epoxy zn yakawanda ine cathodic protection effect. Pendi iyi haina chete kugona kwakasimba kwekubatanidza pamusoro pesimbi yakaputirwa nejecha, asiwo inodzivirira ngura zvakanyanya uye inoita basa rakawanda. Nekuwedzera kwerudo rwevanhu, inoshandiswa zvakanyanya mumhando dzese dzeinjiniya yekudzivirira ngura yesimbi.

Sechishandiso chepakutanga chine zvikamu zviviri chinodzivirira ngura, chishandiso chepakutanga chine zinc yakawanda chine hunhu hwakanaka hwekudzivirira ngura, kunamira, hunhu hwemakanika uye hunhu hwekutsigira. Chakakodzera simbi inodzivirira ngura munzvimbo dzine mhepo, uye chinoshandiswa zvakanyanya mukudzivirira ngura, mhepo ine makemikari, nzvimbo dzegungwa nedzimwe nzvimbo dzinodzivirira ngura uye dzinodzivirira mamiriro ekunze, dzakadai se: Chimiro chesimbi yemiti, mabhiriji makuru, michina yechiteshi, michina inorema, michina yekuchera mafuta nemidziyo yemugodhi, mapaipi akavigwa, tangi rekuchengetera mafuta rusvingo rwekunze, tangi regesi rusvingo rwekunze uye chikepe nedhiki pamusoro pemvura uye mamwe maitiro esimbi sisitimu inorwisa ngura inorema.

primer ine epoxy zinc yakawanda

Kana pendi ine zinc yakawanda ikashandiswa paprimer yebhiriji resimbi, primer yekunze yetangi rekuchengetedza inodzivirira kuora, pendi yekunze yemudziyo inodzivirira kuora, pendi yechimiro chesimbi inodzivirira kuora, primer yeshell yechikepe, kudzivirira kuora kwegomba rechikepe, uye dzimwe nzvimbo dzemumhepo, zvakakosha kusarudza sisitimu inotsigira zvine mwero, uye kushandisa chimiro chakafanana chependi yepakati pepakati pepende kuti ikwanise kuchengetedza substrate kwenguva refu. Kazhinji, sisitimu yekuvhara ye epoxy zinc-rich primer + epoxy iron intermediate paint + acrylic polyurethane topcoat yakakura zvikuru.

Mukushandiswa chaiko, chikamu chependi nechinhu chinoporesa chinofanira kuenderana nezvinodiwa nemugadziri, uye musanganiswa chaiwo unoshandiswa, nzira inowanzoshandiswa yekukwesha ndeyekupfapfaidza negasi, kupfapfaidza pasina mhepo, kuputira bhurashi, nezvimwewo, zvichienderana nechimiro chesimbi, nzvimbo uye zvimwe zvinosarudzwa zvine musoro, ukobvu hwekukwesha firimu rependi hunofanira kudzorwa pa70-80μm kuti uwane mhedzisiro iri nani yekudzivirira ngura.

Muchinyorwa chiri pamusoro apa, tinosuma sisitimu yekuputira inoshandiswa zvakanyanya. Patinenge tichiita basa reiyi sisitimu yekuputira, tinofanira kuve nechokwadi chekuti mushure mekupedzwa kweprimer coating, pendi yepakati inopendwa mushure memaawa makumi maviri nemana. Pendi yepakati haina kunamatira zvakanaka chete, inodzivirira ngura, inochengetedza uye ine gobvu, asiwo inovandudza ukobvu hwese hwefirimu rependi uye inowedzera mhedzisiro yekudzivirira ngura. Ukobvu hwefirimu hunogona kupfapfaidzwa kusvika 100-150μm kuti uwane ukobvu hwakatarwa hwefirimu.

Kana pendi yepakati yapera, acrylic polyurethane topcoat inoiswa mukati memaawa makumi maviri nemana. Topcoat iyi ipendi inoshanda zvakanyanya inodzivirira ngura ine simba rekudzivirira mamiriro ekunze, inodzivirira acid nealkali, ine firimu rakasimba uye inoshongedza zvakanaka. Kuburikidza nekudzivirira kwependi yepamusoro, epoxy coating yepasi inodzivirirwa nemwaranzi ye ultraviolet neupfu, uye inopa dziviriro yakasimba uye kushongedza.
