Iumbala steel plateendaweni esemkhathini zichayeka ekukhanyeni kwelanga, umoya, isihlabathi, imvula, iqhwa, isithwathwa namazolo, kanye nokushintsha kwezinga lokushisa kanye nomswakama unyaka wonke.Lezi yizo zonke izici ezibangela ukuba umbala we-tile wensimbi ugle.Ngakho kanjani ukubavikela?
1. Thermal spray aluminium eyinhlanganisela enamathela
Lena indlela ehlala isikhathi eside yokunqanda ukugqwala esebenza kahle njengokufaka ama-galvanizing ediphu elishisayo.Indlela eqondile iwukuqala nge-sandblast bese ususa ukugqwala ebusweni bezingxenye zensimbi ukuze uveze ukucwebezela kwensimbi futhi wenze indawo engaphezulu ibe rough.Bese usebenzisa ilangabi le-acetylene-oksijeni ukuze uncibilikise intambo ye-aluminum ephakelwa ngokuqhubekayo, futhi usebenzise umoya ocindezelwe ukuwuphephetha phezu kwengxenye yensimbi ukuze wenze isifutho se-aluminium emise okwekhekheba lezinyosi.Okokugcina, ama-capillary pores agcwaliswa ngopende njenge-epoxy resin noma upende we-neoprene ukuze enze i-coating eyinhlanganisela.Le ndlela ayikwazi ukusetshenziswa odongeni lwangaphakathi lwezingxenye ze-tubular, ngakho-ke zombili iziphetho zezingxenye ze-tubular kufanele zivalwe kahle ukuze udonga lwangaphakathi lungagqwali.
2. Indlela yokumboza
Izakhiwo zokunqanda ukugqwala zezindlela zokumboza ngokuvamile azilungile njengezindlela zokulwa nokugqwala zesikhathi eside.Ngakho-ke, kunezakhiwo eziningi zensimbi zasendlini noma izakhiwo zensimbi zangaphandle okulula ukuzivikela.Isinyathelo sokuqala ekwakhiweni kwendlela yokumboza ukususwa kokugqwala.Ukugqoka okuphezulu kuncike ekususeni ukugqwala okuphelele.Ngakho-ke, izimbozo ezinesidingo esikhulu ngokuvamile zisebenzisa i-sandblasting kanye nokuqhuma kwesibhamu ukususa ukugqwala, ukuveza ukucwebezela kwensimbi, futhi kususe konke ukugqwala namafutha.Izindwangu ezifakwe esizeni zingasuswa ngesandla.Ukukhethwa kokugqoka kufanele kucabangele indawo ezungezile.Izembatho ezihlukene zinokubekezelelana okuhlukile ezimweni ezihlukene zokugqwala.Izigqoko ngokuvamile zihlanganisa i-primer ne-topcoat.I-primer iqukethe i-powder eyengeziwe kanye ne-base material encane.Ifilimu ilukhuni, inokunamathela okuqinile ensimbi, futhi inokunamathela kahle kwejazi eliphezulu.Ijazi eliphezulu linezinto eziningi eziyisisekelo futhi ifilimu iyacwebezela, engavikela i-primer ekugqwaleni komkhathi futhi imelane nesimo sezulu.
Kunemibuzo mayelana nokuhambisana kwezingubo ezihlukene.Uma ukhetha izigqoko ezihlukene ngaphambi nangemva kwalokho, kufanele unake ukuhambisana kwazo.Ukugqoka kufanele kusetshenziswe ngokushisa okufanelekile nomswakama.Indawo yokwakha yokumboza kufanele ibe nothuli oluncane futhi akufanele kube khona ukufingqa ebusweni bezingxenye.Ungabeki imvula phakathi namahora angu-4 ngemva kokupenda.Ukugqoka kuvame ukwenziwa izikhathi ezi-4 kuya kwezi-5.Ubukhulu befilimu kapende owomile bungu-150μm kumaphrojekthi angaphandle kanye no-125μm kumaphrojekthi angaphakathi, ngephutha elivumelekile elingu-25μm.Ogwini lolwandle noma olwandle noma endaweni egqwala kakhulu, ukujiya okuphelele kwefilimu kapende owomile kungakhushulwa ku-200~220μm.
3. Indlela yokuvikela i-Cathodic
Ukunamathisela insimbi ecace kakhudlwana ebusweni besakhiwo sensimbi kungena esikhundleni sokugqwala kwensimbi.Okuvame ukusetshenziswa ezakhiweni ezingaphansi kwamanzi noma ezingaphansi komhlaba.Amathayela ensimbi anombala awumkhiqizo ongabizi kakhulu.Nakuba imali yokuqala yokutshala imali ingase ibonakale incane, ngokwezindleko zokusetshenziswa kwesikhathi eside, iyonga izindleko ngoba umkhiqizo unomsebenzi omude futhi awunaso isikhungo.Kunesimo sokushintshwa.Kithina, konga umsebenzi, umzamo kanye nemali.
Ngethemba ukuthi lesi sihloko siwusizo kuwe.Sicela uvale le webhusayithi ukuze uthole izindaba ezibuyekeziwe.
