Kev xaiv cov txheej txheej sab hauv rau cov kaus poom tinplate (piv txwv li, tin-coated steel poom) feem ntau yog nyob ntawm qhov xwm txheej, txhawm rau txhim kho lub peev xwm corrosion, tiv thaiv cov khoom zoo, thiab tiv thaiv qhov tsis zoo ntawm cov hlau thiab cov khoom. . Hauv qab no yog cov ntsiab lus thiab cov kev xaiv sib xws ntawm cov txheej sab hauv:
1. Dej haus (xws li dej qab zib, kua txiv hmab txiv ntoo, thiab lwm yam)
Rau cov dej haus uas muaj cov khoom xyaw acidic (xws li kua txiv qaub, kua txiv kab ntxwv, thiab lwm yam), cov txheej txheej sab hauv feem ntau yog epoxy resin txheej lossis phenolic resin txheej, vim tias cov txheej txheem no muaj cov kua qaub zoo heev, tiv thaiv kev cuam tshuam ntawm cov ntsiab lus thiab cov hlau thiab zam. off-flavors los yog paug. Rau cov dej haus uas tsis yog-acidic, ib qho yooj yim polyester txheej (xws li polyester zaj duab xis) yog feem ntau txaus.
2. Npias thiab lwm yam dej cawv
Cov dej cawv muaj zog ntau dua rau cov hlau, yog li epoxy resin lossis polyester txheej feem ntau siv. Cov coatings zoo cais cov cawv ntawm cov hlau, tiv thaiv corrosion thiab tsw hloov. Tsis tas li ntawd, qee cov coatings muab kev tiv thaiv oxidation thiab tiv thaiv lub teeb kom tiv thaiv cov hlau saj los ntawm leaching rau hauv dej haus.
3. Khoom noj khoom haus (xws li, kua zaub, zaub, nqaij, thiab lwm yam)
Rau cov khoom noj uas muaj roj ntau lossis acid acid, kev xaiv txheej txheej yog qhov tseem ceeb tshwj xeeb. Cov txheej txheej sab hauv muaj xws li epoxy resin, tshwj xeeb tshaj yog epoxy-phenolic resin composite coatings, uas tsis yog tsuas yog muab cov kua qaub tab sis kuj tuaj yeem tiv taus qhov kub thiab txias ntau dua, kom ntseeg tau lub sijhawm ntev thiab txee lub neej ntawm cov zaub mov.
4. Cov khoom noj mis nyuj (piv txwv li, mis nyuj, khoom siv mis nyuj, thiab lwm yam)
Cov khoom siv mis nyuj xav tau cov txheej txheem ua haujlwm siab, tshwj xeeb tshaj yog kom tsis txhob muaj kev cuam tshuam ntawm cov txheej txheem thiab cov protein thiab cov rog hauv cov khoom noj siv mis. Polyester coatings feem ntau yog siv raws li lawv muaj cov kua qaub zoo heev, oxidation tsis kam, thiab ruaj khov, zoo khaws cov tsw ntawm cov khoom siv mis nyuj thiab ua kom lawv lub sijhawm ntev tsis muaj kev sib kis.
5. Cov roj (piv txwv li, cov roj siv tau, cov roj lubricating, thiab lwm yam)
Rau cov khoom siv roj, cov txheej txheej sab hauv yuav tsum tsom rau kev tiv thaiv cov roj los ntawm kev hnov mob nrog cov hlau, kom tsis txhob muaj ntxhiab tsw lossis paug. Epoxy resin lossis polyester coatings feem ntau yog siv, raws li cov txheej txheem no zoo cais cov roj los ntawm cov hlau sab hauv ntawm lub kaus poom, ua kom muaj kev ruaj ntseg thiab kev nyab xeeb ntawm cov khoom siv roj.
6. Tshuaj los yog xim
Rau cov khoom tsis yog khoom noj xws li tshuaj lom neeg los yog xim, cov txheej sab hauv yuav tsum muaj kev tiv thaiv corrosion, tshuaj tiv thaiv, thiab kub-resistant. Epoxy resin coatings los yog chlorinated polyolefin txheej yog feem ntau xaiv, raws li lawv zoo tiv thaiv cov tshuaj tiv thaiv thiab tiv thaiv cov ntsiab lus.
Summary of Inner Coating Functions:
• Corrosion resistance: Tiv thaiv kev cuam tshuam ntawm cov ntsiab lus thiab cov hlau, ua rau lub neej ntev.
• Tiv thaiv kom tsis txhob kis kab mob: Tsis txhob tso cov hlau nplaum los yog lwm yam tsis zoo rau hauv cov ntsiab lus, kom ntseeg tau tias saj zoo.
• Sealing zog: Txhim khu lub peev xwm sealing kev ua tau zoo, kom ntseeg tau tias cov ntsiab lus tsis cuam tshuam los ntawm lwm yam.
• Oxidation kuj: Txo cov ntsiab lus ntawm cov pa oxygen, ncua cov txheej txheem oxidation.
• Thaum tshav kub kub tsis kam: tshwj xeeb yog qhov tseem ceeb rau cov khoom uas ua rau kub kub (piv txwv li, zaub mov kom tsis muaj menyuam).
Kev xaiv cov txheej txheej sab hauv tuaj yeem ua kom muaj kev nyab xeeb thiab zoo ntawm cov khoom ntim khoom thaum ua tau raws li cov qauv kev nyab xeeb thiab cov kev cai ib puag ncig.
