1.Dab tsi yog cov teeb meem ntawm galvanized coils hauv qhov chaw txias txias?
High humidity thiab condensation: Qhov kub thiab txias sib txawv ntawm sab hauv thiab sab nraum lub txias cia ua rau nws yooj yim rau ya raws nyob rau hauv cov huab cua kom condense rau hauv ib zaj duab xis ntawm hlau nto, tsim ib tug tsis tu ncua tej yam kev mob rau electrochemical corrosion.
Corrosive media:
Cov khoom hauv qhov chaw txias txias (xws li cov nqaij nruab deg, nqaij, thiab txiv hmab txiv ntoo thiab zaub) tso cov khoom corrosive xws li chloride ions, sulfate ions, thiab ammonia.
Brine thiab dej khov ntxiv rau kev khaws cia kuj ua rau kom cov chloride ion concentration hauv ib puag ncig.
Qhov kub thiab txias hloov pauv: Lub evaporator tau ua kom sov thiab defrosted tsis tu ncua, ua rau cov khoom nyob ib puag ncig muaj kev kub ntxhov thiab txias, uas ua rau kom tawg thiab xeb ntawm cov txheej galvanized.
Txiav corrosion: Qhov no yog Achilles pob taws ntawm cov khoom siv galvanized hauv qhov txias cia. Txhua qhov chaw txiav, drilled qhov, thiab cov ntsia hlau sib txuas tsim thaum lub sijhawm ua khoom siv thiab kev teeb tsa ua kom pom cov hlau substrate. Corrosion nyiam tshwm sim nyob rau hauv cov cheeb tsam no thiab sai sai kis mus rau sab hauv, ua rau tsis muaj zog structural zog thiab liab xeb paug.
2.Dab tsi yog qee qhov kev thov uas tsis pom zoo rau cov galvanized coils lossis muaj kev pheej hmoo siab - nyob rau hauv qhov txias txias?
Evaporator (cua txias) vaj tse thiab cov qauv sab hauv: ncaj qha raug rau qis - kub, siab - huab cua thiab dej defrost, lawv corrode sai tshaj plaws.
Cia txee thiab racks: ncaj qha mus rau corrosive gases thiab condensed dej tawm los ntawm cov khoom.
Qab nthab thiab phab ntsa vaj huam sib luag (sab hauv) ntawm qis- qhov kub thiab txias, siab- cov chaw cia khoom: Condensation tuaj yeem ntws raws cov vaj huam sib luag thiab sib sau ua ke hauv qhov txiav, ua rau xeb ntxov ntxov.
Cov yeeb nkab txhawb nqa thiab hangers: raug cov av noo rau lub sijhawm ntev, lawv nyuaj rau kho thiab hloov.
3.Dab tsi yog daim ntawv thov scenarios ntawm galvanized coils nyob rau hauv txias cia?
Cov txheej txheem cia txias (xws li cov phab ntsa sab nrauv thiab lub ru tsev): Cov chaw no muaj qhov kub thiab txias qis dua, ua rau muaj qhov tsis zoo corrosive.
Cov chav qhuav qhuav lossis chav tsis muaj: Cov chaw no muaj qhov chaw me me.
Kev tiv thaiv sab nraud rau qee yam khoom siv: Cov cheeb tsam no tiv thaiv los ntawm kev raug ncaj qha mus rau lub hauv paus, qis - kub, siab - cov av noo.
4.Can zinc-aluminium-magnesium coil siv los hloov galvanized kauj?
Kev pom zoo heev raws li kev hloov kho rau galvanized kauj.
Qhov zoo:
Kev tiv thaiv corrosion zoo heev: Nws cov corrosion kuj yog 5-20 npaug ntau dua li cov galvanized coil ntawm tib lub thickness, ua rau nws tiv taus qhov hnyav ntawm qhov txias cia.
Kev txiav tus kheej zoo- kho muaj peev xwm: Qhov no yog nws qhov txiaj ntsig tseem ceeb tshaj plaws. Cov khoom siv corrosion ntawm zinc-aluminium-magnesium txheej zoo npog qhov chaw txiav, ua rau ncua kev tsim cov xeb liab.
Zoo heev khawb kuj.
Txawm hais tias tus nqi ntawm chav tsev siab dua galvanized coil, xav txog lub neej ntev kev pab cuam thiab txo tus nqi kho, tag nrho cov nqi -kev ua tau zoo yog siab heev.
5.Puas stainless hlau coils hloov galvanized coils?
304 lossis 316 stainless hlau, tshwj xeeb, yog qhov kev xaiv zoo tshaj plaws rau kev tiv thaiv corrosion.
Qhov zoo: Yuav luag xeb- tiv taus, siab zog, thiab ua kom huv si zoo.
Disadvantages: Tus nqi siab thiab ua haujlwm nyuaj.
Daim ntawv thov tsim nyog: Cov ntawv thov uas xav tau cov qauv siab tshaj plaws ntawm kev nyiam huv thiab kev ntseeg siab, xws li cov evaporator loj, cov ntaub ntawv txias cia hauv cov chaw ua zaub mov, thiab cov qauv kev txhawb nqa tseem ceeb.
