I I-primer evame ukusetshenziswa yokulwa nokugqwala kanye ne-anti-rust yokuvimbela ukugqwala kwesakhiwo sensimbi iyi-primer ecebile nge-epoxy zn enomphumela wokuvikela i-cathodic. Upende awugcini nje ngokuba nekhono lokunamathisela eliqinile ebusweni bensimbi ebhujiswe ngesihlabathi, kodwa futhi unokumelana okuqinile kokugqwala kanye nokusebenza okubiza kakhulu. Njengoba uthando lwabantu lwanda, lusetshenziswa kabanzi kuzo zonke izinhlobo zobunjiniyela bokulwa nokugqwala kwesakhiwo sensimbi.

Njenge-primer yokulwa nokugqwala enezingxenye ezimbili, i-primer ecebile nge-epoxy zinc inezakhiwo ezinhle kakhulu zokulwa nokugqwala, ukunamathela, izakhiwo zemishini kanye nezakhiwo ezisekelayo. Ifanelekela insimbi yokulwa nokugqwala endaweni enomoya, futhi isetshenziswa kabanzi ekulweni nokugqwala okujwayelekile, emoyeni wamakhemikhali, endaweni yolwandle nakwezinye izinto ezilwa nokugqwala kanye nokumelana nesimo sezulu, njenge: Isakhiwo sensimbi yesitshalo, amabhuloho amakhulu, imishini yechweba, imishini esindayo, ukumbiwa kwamafutha kanye nemishini yezimayini, amapayipi agqitshwe, udonga lwangaphandle lwethangi lokugcina uwoyela, udonga lwangaphandle lwethangi legesi kanye ne-ship hull kanye nedekhi ngaphezu komugqa wamanzi kanye nohlelo lwensimbi olunzima lokulwa nokugqwala.

i-primer ecebile nge-zinc e-epoxy

Uma upende ocebile nge-zinc usetshenziswa ku-primer yebhuloho lesakhiwo sensimbi, i-primer yangaphandle yethangi lokugcina impahla, upende wangaphandle we-container we-anticorrosive, upende we-anticorrosive wesakhiwo sensimbi, i-primer yegobolondo lemikhumbi, ukuvimbela ukugqwala kwesakhiwo se-port kanye nezinye izindawo ezizungezile, kubalulekile ukukhetha uhlelo olusekelayo olufanele, bese usebenzisa isakhiwo esifanelanayo sopende we-prime-intermediate penti-top ukuze kufezwe injongo yokuvikela isikhathi eside i-substrate. Ngokuvamile, uhlelo lokumboza lwe-primer ye-epoxy zinc-rich + epoxy iron intermediate paint + acrylic polyurethane topcoat lubanzi kakhulu.

Enkambisweni yokusetshenziswa kwangempela, isilinganiso sopende kanye ne-ejenti yokwelapha kufanele sihambisane nezidingo zomenzi, futhi isihlanzi esikhethekile esisetshenziswayo, indlela yokuxubha evame ukusetshenziswa ukufutha ngegesi, ukufutha ngaphandle komoya, ukumboza ngebhulashi, njll., ngokuya ngesimo sesakhiwo sensimbi, indawo kanye nokunye ukukhetha okunengqondo, ubukhulu bokuxubha ngefilimu yopende kufanele bulawulwe ku-70-80μm ukuze kufezwe umphumela ongcono wokulwa nokugqwala.

Esihlokweni esingenhla, sethula uhlelo lokumboza olusetshenziswa kabanzi. Lapho senza umsebenzi walolu hlelo lokumboza, kufanele siqinisekise ukuthi ngemva kokuqedwa kokumboza okuyinhloko, upende ophakathi uyapendwa ngemva kwesikhawu samahora angama-24. Upende ophakathi awugcini nje ngokuba nokunamathela okuhle kakhulu, ukulwa nokugqwala, ukuvikela kanye nokumboza okujiyile, kodwa futhi uthuthukisa ukujiya okuphelele kwefilimu yopende futhi uthuthukise umphumela wokulwa nokugqwala. Ukujiya kwefilimu kungafuthwa kufike ku-100-150μm ukuze kufezwe ukujiya kwefilimu okucacisiwe.

Ngemva kokuqeda upende ophakathi nendawo, i-acrylic polyurethane topcoat ifakwa ngesikhawu samahora angama-24. I-topcoat iyipende elivikela ukugqwala elisebenza kahle kakhulu elinokumelana nesimo sezulu okuphezulu, ukumelana ne-asidi ne-alkali, ifilimu eqinile kanye nokuhlobisa okuhle. Ngokuvikela ungqimba lopende oluphezulu, i-epoxy coating engezansi igwenywa yimisebe ye-ultraviolet kanye ne-powder, futhi inikeza isivikelo kanye nokuhlobisa okuqinile.
