1.Cov ntsiab cai tseem ceeb yog dab tsi?
Lub hom phiaj yog tshem tawm cov zinc oxide hais thaum tiv thaiv cov xim tsis zoo rau qhov loj tshaj plaws. Tsis txhob siv cov txheej txheem hnyav uas tuaj yeem khawb lossis yaj cov xim pleev xim.
2.Dab tsi tuaj yeem ntsuas ua ntej vuam?
Ua ntej- sib tsoo ntawm qhov chaw vuam: Maj mam txhuam thaj tsam li ntawm 20-30mm ntawm ob sab ntawm vuam seam siv cov ntaub qhwv los yog cov ntawv xuab zeb zoo heev (xws li, 400# lossis siab dua) kom tshem tawm cov xim txheej thiab ib feem ntawm zinc txheej, nthuav tawm cov hlau substrate. Qhov no yog txoj kev zoo tshaj plaws thiab pom zoo.
Kev siv vuam anti-spatter agent: Txau cov tshuaj tiv thaiv tshwj xeeb -spatter tus neeg sawv cev rau cov txheej txheem ntawm ob sab ntawm lub vuam seam los tsim cov yeeb yaj kiab tiv thaiv, tiv thaiv zinc pos huab los ntawm adhering thiab ua kom yooj yim los so tom qab ua tiav.
Siv cov khoom siv vuam tshwj xeeb thiab cov txheej txheem:
Xaiv qhov qis- cov pas nrig vuam / hlau: xws li flux-cored hlau, uas txo cov zinc evaporation.
Kev tswj cov vuam tsis sib xws: Siv qhov qis dua tam sim no thiab qhov nrawm nrawm nrawm txo cov cua sov tawm.
Txhim kho vuam txheej txheem: Tilting lub vuam torch rov qab (txoj txoj kev) tso cai rau lub arc quab yuam los thawb lub slag thiab zinc vapor mus rau qhov chaw raug.
3.Yuav ua li cas zinc pos huab nrog ib qho kev ntxhib los mos zoo nkauj yuav raug tshem tawm ntawm lub cev?
Cov cuab yeej: Siv cov yas scraper, ntoo scraper, los yog cov khoom siv tooj dag tshwj xeeb. Cov hlau no softer dua li cov ntawv ua ntej-coated steel thiab yuav tsis khawb cov txheej tsis zoo.
Txoj kev: Maj mam txhuam cov zinc oxide uas tau tsa ntawm lub kaum sab xis me me (yuav luag sib npaug rau saum npoo ntawm daim ntawv). Tsis txhob siv cov hniav hlau los yog tawv scrapers.
4.Txoj kev txhuam thiab tu cov kauj ruam yog dab tsi?
Cov cuab yeej: Siv cov txhuam nylon qhuav, mos (xws li txhuam txhuam) lossis txhuam txhuam (ntsuab, sab ntxhib) kom maj mam txhuam hauv tib qho kev taw qhia.
Lub hom phiaj: txhawm rau tshem cov hmoov av. Tom qab ntawd so qhov chaw nrog ib daim ntaub huv, ntub dej (koj tuaj yeem siv dej los yog tshuaj ntxuav tes tsis zoo) kom tshem tawm cov khoom seem.
Ceeb Toom: Tsis txhob txhuam kom nrawm rau hauv lub voj voog kom tsis txhob kis tus kab mob hazy residue.
5.Qhov kev coj ua twg yog txwv tsis pub?
Tsis txhob siv cov ntaub plaub los yog cov ntaub plaub hlau: Cov no yuav ua rau cov txheej txheem hnyav heev, ua rau muaj kev xeb ntau heev.
Tsis txhob siv cov kua qaub uas muaj zog (xws li cov concentrated hydrochloric acid) rau kev so ncaj qha: Cov no yuav ua rau tag nrho cov zinc txheej thiab txheej.
Tsis txhob siv cov abrasives hnyav (xws li coarse sib tsoo log): Tshwj tsis yog tias koj npaj yuav rov pleev xim rau tag nrho cheeb tsam.
Tsis txhob tsis quav ntsej kev kho: Kev tu yam tsis muaj kev kho yog sib npaug rau tsuas yog "surface beautification," thiab cov khoom tiv thaiv -corrosion ploj, cia xeb pib los ntawm qhov ntawd.
