Coatings: Izinjongo kanye nobuchwepheshe

Metal izakhiwo kuletha izinzuzo eziningana njengoba kuqhathaniswa ne izakhiwo sasakhiwe ngokhonkolo kwagcizelela ngokuyinhloko kuba isisindo kakhulu kancane ngenkathi sigcina amandla adingekayo. Ngaphezu kwalokho, isakhiwo metal kungenziwa zezikhali, futhi ukwakhiwa yabo kungenzeka nganoma isiphi isikhathi sonyaka. Kodwa metal ukuze avikeleke emimoyeni emiphumeleni elimazayo yezinto zemvelo (ilanga, amanzi, umoya, ukushisa izinguquko), kanye kanye nezindlela ukuvikelwa ngokukhethekile (ekuqiniseni, nitrotsementirovanie) wasebenzisa indlela ezifana yokudweba metal. Isendlalelo enamathela ongavikela metal avela kubo bonke la maqiniso angenhla. Ngaphezu kwakho konke, Umbala, metal sisetshenziswa kakhulu ukungadluliseli i ukubukeka yobuhle ukwakhiwa.

Ngokukhethekile kufanele ikhokhwe kukhethwa ezinengilazi. Metal inki kumele kube ekhethekile kokuba izici ezithile. Okwamanje, lokhu kubangela akukho nobunzima, nomkhiqizi ngamunye kuhlanganisa emgqeni walo okukhethekile upende ngoba metal.

Painting metal izakhiwo - zenziwe futhi umsebenzi isikhathi, okuyinto edinga amakhono athile. Lokhu kungenxa nje kuphela ubuchwepheshe enamathela, kodwa futhi neqiniso lokuthi izakhiwo ezinjalo ziyathandeka mikhulu futhi kubenze ijazi kapende ngisho simple. imiklamo ezinjalo zivame obudaywe alpinism yezimboni kuphela ochwepheshe.

Coatings iqala saziso ukuqeqeshwa ebusweni. Umsebenzi onjalo kwangaphambilini okudingekayo ukuthuthukisa adhesion (adhesion), kanye enamathela izakhi zensimbi. Isinyathelo sokuqala siwukuba ukususa upende omdala uma umuntu otholakele. Khona-ke, i-Ukusincwela igawula futhi ukugqwala. Isinyathelo esilandelayo kuyoba wokuhlanza bonke ubuso kuqhuma manual, mechanical noma olwalwenza kusuka ukungcola nothuli - Kulesi sigaba kunoma yiliphi icala ungaphuthelwa, ngisho noma ebusweni elingaphandle ibukeka ahlanzekile. On metal njalo iqukethe izinhlayiya lesinye isizwe, futhi uma akakhishwanga, upende ozosigingqela izakhi noma izakhiwo uyomenzela ungqimba non-iyunifomu, okuholela yokuthi umbala izakhiwo steel kuzokwenziwa kahle.

Ngaphezu kwalokho kungenzeka kwenziwa wokucwebezelisa ebusweni - le nqubo futhi isiza ukuthuthukisa upende adhesion nensimbi. Isinyathelo esilandelayo - degreasing, it is eyenziwa usebenzisa ane-alikhali noma esidi emulsion izimali. Ngemva kokugeza ezinjalo kufanele ulinde - umklamo kumele kube yome ngokuphelele ngaphambi imidwebo. Inqubo wokugcina iyona nokulungiselela priming - ukwelashwa elilodwa noma amabili umgodi ngezinto zokwakha ezikhethekile, ungqimba yesibili sisetshenziswa kuphela emva omiswe ephelele kuqala. Ngemva priming uqhubeke ngqo staining.

Into kuphela ukukhumbula - ungenzi aphumule isikhathi eside kungekho phakathi ukulungiselela ebusweni, priming nokusebenzisa upende, ngoba timphawu tesakhiwo kungenziwa kabusha enobuthi futhi ukumboza amanga kubi. Kodwa uma zonke imisebenzi abazenzi ngendlela efanele, impilo umgwengwezi akuyona eminyakeni engaphansi kwengu-3.5.
