1.Dab tsi yog xeb- pov thawj txoj cai ntawm galvanized coils?
Txoj cai xeb- pov thawj txoj cai ntawm galvanized coils nyob hauv zinc txheej tiv thaiv cov hlau sab hauv los ntawm "kev txi anode" mechanism. Feem ntau, galvanized coils lawv tus kheej tsis xeb.
Qhov "rust" koj pom feem ntau poob rau hauv ob pawg:
Dawb xeb: Cov hmoov dawb tsim thaum zinc reacts nrog dej thiab carbon dioxide nyob rau hauv ib qho chaw ntub dej, qhov cua tsis zoo. Qhov no yog qhov tseeb yog cov khoom siv corrosion ntawm zinc.
Liab xeb: Liab xeb tsuas yog tsim thaum cov zinc txheej yog tag nrho corroded, los yog thaum cov ntawv hlau raug txiav los yog khawb, nthuav tawm cov hlau sab hauv.
2.Dab tsi yog kev puas tsuaj ntawm sandblasting?
Sandblasting (txawm hais tias nrog steel grit, steel txhaj, los yog silica xuab zeb) yog ib tug haib heev nto kev kho mob txoj kev tsim los kom tshem tawm tag nrho cov coatings ntawm ib tug nto.
Thaum koj sandblast galvanized coils, koj indiscriminately rhuav tshem qhov tseem ceeb, tiv thaiv zinc txheej thiab passivation zaj duab xis ntawm qhov chaw. Thaum kawg, koj tau txais ib lub yob ntawm ci, ua kom txias tag -cov ntawv dov, tsis yog ntawv galvanized.
3.Dab tsi yog qhov tshwm sim ntawm sandblasting galvanized coils?
Kev poob mus tas li ntawm kev tiv thaiv corrosion: Koj tau ua haujlwm tshem tawm nws cov xeb-resistant "armor." Cov yob ntawm cov khoom no yuav zoo ib yam li cov khaub thuas txias -rolled steel, sai sai pib xeb hauv huab cua.
Cov nqi galvanizing khib nyiab: Galvanized coils yog kim dua li txias -rolled coils ntawm tib yam specifications, feem ntau yog vim lub galvanized txheej. Sandblasting yog qhov tseem ceeb pov tseg qhov nyiaj ntxiv.
Tej zaum yuav muaj teeb meem tshiab: kev ua haujlwm tsis raug lossis tsis huv abrasive thaum lub sij hawm sandblasting yuav embed impurities rau hauv steel nto, cuam tshuam rau kev siv tom ntej.
4.Dab tsi yog txoj hauv kev zoo los daws cov xeb dawb lossis cov stains me ntawm qhov chaw?
Txoj kev kom raug: Siv txhuam txhuam (xws li txhuam txhuam) thiab dej huv los ntxuav. Rau tawv tawv dawb xeb, yuav siv tau ib tug me me alkaline los yog nruab nrab tshwj xeeb nqus tsev vacuum. Tom qab ntxuav, nco ntsoov yaug kom huv si nrog dej huv thiab cia cua qhuav kom huv si.
Lub hom phiaj: Tshem tawm cov khoom siv corrosion tsis ua rau cov zinc txheej.
5.Dab tsi yog txoj hauv kev zoo los daws cov kab liab liab ntawm cov npoo los yog khawb?
Txoj kev raug: Ua tib zoo tshem tawm cov xeb liab hauv zos siv cov cuab yeej siv tes (xws li txhuam hlau los yog ntawv xuab zeb). Tom qab ntawd, tam sim ntawd siv cov zinc- nplua nuj xim lossis xeb- cov xim tiv thaiv rau cov hlau raug.
Lub hom phiaj: Txhawm rau tshem tawm xeb hauv zos thiab tsim kho "zinc tiv thaiv" txheej.
