1.Dab tsi yog vim li cas theoretically ua tau?
Tus nqi zoo: Galvanized coils feem ntau tsis tshua kim dua cov hlau tsis muaj steel thiab engineering yas, uas tej zaum yuav txaus nyiam rau cov khoom uas qhov kev tswj hwm tus nqi yog qhov tseem ceeb.
Kev tiv thaiv xeb yooj yim: Muab piv rau qhov txias txias- cov ntawv dov, txheej txheej galvanized muab qee qhov kev tiv thaiv xeb, cuam tshuam nrog qee lub sijhawm ya raws thiab qhov chaw ntub dej.
2.Dab tsi yog cov teeb meem tshwm sim hauv kev xyaum?
Extreme Corrosive Ib puag ncig:
High- cov tshuab nqus tsev siab ua haujlwm nyob rau hauv ib puag ncig nrog kev ua haujlwm tas mus li, siab - siv dej vapor, siab - dej siab pos huab, thiab muaj peev xwm ntxuav cov tshuaj (acids thiab alkalis).
Cov txheej galvanized (tshwj xeeb tshaj yog ntawm kev txiav, welds, thiab khoov) yog qhov cuam tshuam rau cov xim dawb thiab xim dub hauv qhov chaw no, nws thiaj li ua rau perforation. Nws qhov kev tiv thaiv corrosion tsis txaus los tiv thaiv cov xwm txheej hnyav ntev - lub sijhawm.
Cov teeb meem tshwm sim thiab txheej txheem:
Cov tsos mob tshwm sim: Cov nyiaj - grey tsos ntawm cov ntawv hlau galvanized muaj qhov kev xav me ntsis ntawm kev lag luam, ua rau nws nyuaj los tsim qhov siab - kawg, sophisticated zoo uas nyiam cov neeg siv khoom. Cov kev kho mob thib ob xws li kev pleev xim yog feem ntau xav tau, nce nqi thiab cov txheej txheem.
Vuam nyuaj: Thaum vuam, zinc txheej evaporates, ua rau cov zinc oxide fumes uas ua rau muaj kev phom sij loj rau cov neeg ua haujlwm. Tsis tas li ntawd, weld zoo yog qhov nyuaj rau lav, thiab qhov chaw weld dhau los ua thawj qhov tsis muaj zog rau corrode.
Kev Tiv Thaiv Kev Tiv Thaiv ntawm Kev Txiav thiab Folds: Ntawm kev txiav, xuas nrig ntaus, thiab khoov cov ntsiab lus, zinc txheej yog puas, nthuav tawm cov hlau sab hauv. Cov chaw no dhau los ua qhov pib ntawm corrosion nyob rau hauv qhov chaw ntub dej, ua rau xeb sai.
3.Yuav ua li cas cov yas yas siv tau rau lub tsev ntawm lub siab - lub tshuab ntxhua khaub ncaws?
Qhov zoo:
Tsis xeb kiag li- pov thawj: Tsis muaj kev cuam tshuam los ntawm dej thiab ya raws corrosion.
Lub teeb yuag: Lub teeb yuag, yooj yim txav thiab nqa.
Tsim kev ywj pheej: Complex, streamlined tsos tuaj yeem tsim los ntawm kev txhaj tshuaj molding, nrog ntau yam xim.
Kev rwb thaiv tsev zoo heev: Muaj kev nyab xeeb zoo li cov khoom siv hluav taws xob.
Tus nqi-zoo: Tus nqi siab- sib tw rau kev tsim khoom loj.
4.Puas yog stainless hlau siv rau lub tsev ntawm siab - siab washers?
Qhov zoo:
Kev tiv thaiv corrosion zoo heev: Resistant rau dej, ya raws, thiab feem ntau cov tshuaj ntxuav cov neeg ua haujlwm, ua rau lub neej ua haujlwm ntev heev.
High structural zog: heev robust thiab check, muaj peev xwm ntawm withstanding hnyav industrial puag ncig.
Kev ua haujlwm zoo: Muaj kev zoo nkauj hauv kev lag luam thiab kev xav zoo siab -.
Disadvantages: tus nqi siab tshaj, hnyav tshaj plaws.
5.Dab tsi yog qhov zoo thiab qhov tsis zoo ntawm kev siv aluminium alloy rau lub tsev ntawm lub siab -lub tshuab ntxhua khaub ncaws?
Qhov zoo: Lub teeb yuag, siab zog, thiab superior corrosion kuj piv rau galvanized steel (tshwj xeeb tshaj yog tom qab anodizing).
Disadvantages: Tus nqi siab dua li cov yas thiab galvanized steel, thiab kev ua haujlwm nyuaj.
