Kev xaiv ntawm txheej sab hauv rau tinplate cants (piv txwv li, tin-co txhim kho steel canents, tiv thaiv cov khoom lag luam zoo, thiab tiv thaiv cov khoom tsis xav tau ntawm cov hlau thiab cov ntsiab lus Cov. Hauv qab no yog cov txheej txheem sib xws thiab cov kev xaiv sib xws ntawm cov txheej txheem sab hauv:
1. Haus (piv txwv li cov dej qab zib, kua txiv, thiab lwm yam)
Rau cov dej haus acidic cov khoom xyaw (xws li kua txiv txiv kab ntxwv, thiab lwm yam khoom siv acid los yog tiv thaiv cov ntsiab lus thiab cov hlau thiab zam Off-flavors lossis paug. Rau cov dej cawv uas tsis muaj acidic, ib qho yooj yim polyester (xws li cov yeeb yaj kiab polyester) feem ntau txaus.
2. Npias thiab lwm yam dej haus cawv
Cov dej cawv yog cov kev xeb ntau dua rau cov hlau, yog li epoxy cob lossis polyester txheej siv tau siv. Cov txheej txheej no tau suav nrog cov cawv los ntawm cov hlau tuaj yeem, tiv thaiv kev xeb thiab cov tsw hloov. Ib qho ntxiv, qee cov txheej txheej muab kev tiv thaiv oxidation thiab lub teeb kev tiv thaiv kom tiv thaiv cov hlau muag los ntawm kev haus dej.
3. Cov khoom noj khoom noj (piv txwv li, kua zaub, zaub, nqaij, thiab lwm yam)
Rau cov roj muaj rog ntau lossis cov khoom noj kua qaub ua ke, cov kev xaiv ntawm txheej yog qhov tshwj xeeb. Txheej txheej sab hauv xws li epoxy cob qhia, uas tsis tsuas yog muab cov kua qaub ntau dua tab sis kuj tseem tuaj yeem tiv thaiv lub sijhawm ntev thiab txee rau cov khoom noj.
4. Cov khoom siv mis nyuj (piv txwv li, mis nyuj, cov khoom noj siv mis, thiab lwm yam)
Cov khoom noj siv mis xav tau cov txheej txheem ua haujlwm siab, tshwj xeeb yog kom tsis txhob muaj kev cuam tshuam ntawm cov txheej thiab cov protein thiab cov rog hauv cov mis nyuj. Polyester txheej yog feem ntau siv raws li lawv muab cov kua qaub zoo nkauj, thiab ruaj khov rau cov tsw ntawm cov khoom noj mis thiab kom lawv cia ntev uas tsis muaj paug.
5. Roj (piv txwv li, cov roj muaj qab, roj lubricating roj, thiab lwm yam)
Txog cov khoom siv roj, cov txheej hauv sab hauv yuav tsum tsom rau kev tiv thaiv cov roj los ntawm kev rov ua nrog cov hlau, tsis txhob muaj cov khoom sib txawv lossis paug. Epoxy Resin lossis Polyester Txheej Txheem yog feem ntau siv, raws li cov txheej txheej no cais cov roj ntawm cov hlau tuaj yeem, ua kom muaj kev nyab xeeb thiab kev nyab xeeb ntawm cov khoom roj.
6. Tshuaj lom neeg lossis pleev xim
Rau cov khoom lag luam uas tsis yog cov khoom noj lossis cov xim av, cov txheej hauv sab hauv yuav tsum muaj cov muaj zog corrosion, tshuaj lom neeg tiv thaiv, thiab siab-kub tsis kam. Epoxy Resin txheej lossis chlorinated polyolefin txheej yog xaiv tau, raws li lawv tau txais txiaj ntsig zoo tshuaj lom thiab tiv thaiv cov ntsiab lus.
Ntsiab lus ntawm cov txheej txheem sab hauv cov haujlwm:
• Corrosion Kuj: tiv thaiv kev tawm tsam ntawm cov ntsiab lus thiab cov hlau, txuas lub neej.
• Kev tiv thaiv cov kev paug: zam kev ua kom tsis txhob muaj hlau ntawm cov hlau qab los yog lwm yam tawm ntawm cov ntsiab lus, ua kom tau saj zoo.
• Cov khoom lag luam sealing: txhim kho cov tuaj yeem sib khi ua tau zoo, kom ntseeg tau tias cov ntsiab lus tsis cuam tshuam los ntawm lwm cov sab nraud.
• Oxidation tsis kam: txo qhov raug rau cov ntsiab lus mus rau oxygen, ncua cov txheej txheem oxidation.
• Cov cua sov: tshwj xeeb yog qhov tseem ceeb rau cov khoom lag luam uas yauv ua cua sov siab (piv txwv li, khoom noj kom tsis muaj zaub mov).
Xaiv qhov zoo sab hauv txheej tuaj yeem ua kom muaj kev nyab xeeb thiab ua tau zoo ntawm cov khoom ntim khoom thaum ntsib cov qauv kev nyab xeeb thiab ib puag ncig kev nyab xeeb.
