Kev xaiv cov txheej sab hauv rau cov kaus poom tinplate (piv txwv li, cov kaus poom hlau uas muaj txheej tin) feem ntau nyob ntawm qhov xwm txheej ntawm cov ntsiab lus, lub hom phiaj yog los txhim kho qhov kev tiv thaiv xeb ntawm lub kaus poom, tiv thaiv cov khoom zoo, thiab tiv thaiv kev tsis sib haum xeeb ntawm cov hlau thiab cov ntsiab lus. Hauv qab no yog cov ntsiab lus feem ntau thiab cov kev xaiv sib xws ntawm cov txheej sab hauv:
1. Cov dej haus (piv txwv 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), lub txheej sab hauv feem ntau yog epoxy resin txheej lossis phenolic resin txheej, vim tias cov txheej no muaj kev tiv thaiv acid zoo heev, tiv thaiv kev sib xyaw ntawm cov ntsiab lus thiab cov hlau thiab zam kev tsis zoo lossis kev ua qias tuaj. Rau cov dej haus uas tsis muaj acidic, ib txheej polyester yooj yim dua (xws li polyester zaj duab xis) feem ntau txaus.
2. Cawv thiab lwm yam dej cawv
Cov dej haus cawv muaj zog dua rau cov hlau, yog li ntawd feem ntau siv cov tshuaj epoxy resin lossis polyester coatings. Cov tshuaj coatings no cais cov cawv tawm ntawm lub qhov hlau, tiv thaiv kev xeb thiab kev hloov pauv saj. Tsis tas li ntawd, qee cov tshuaj coatings muab kev tiv thaiv oxidation thiab kev tiv thaiv lub teeb kom tiv thaiv cov saj hlau kom tsis txhob nkag mus rau hauv cov dej haus.
3. Cov khoom noj (piv txwv li, kua zaub, zaub, nqaij, thiab lwm yam)
Rau cov khoom noj uas muaj roj ntau lossis muaj kua qaub ntau, kev xaiv cov txheej txheej yog qhov tseem ceeb heev. Cov txheej txheej sab hauv feem ntau suav nrog epoxy resin, tshwj xeeb tshaj yog epoxy-phenolic resin composite coatings, uas tsis tsuas yog tiv taus kua qaub xwb tab sis kuj tuaj yeem tiv taus qhov kub thiab txias siab dua, ua kom ntseeg tau tias cov khoom noj khaws cia tau ntev thiab siv tau ntev.
4. Cov khoom noj mis nyuj (piv txwv li, mis nyuj, cov khoom noj mis nyuj, thiab lwm yam)
Cov khoom noj mis nyuj xav tau cov txheej txheej ua haujlwm siab, tshwj xeeb tshaj yog kom tsis txhob muaj kev sib cuam tshuam ntawm cov txheej txheej thiab cov protein thiab cov rog hauv cov mis nyuj. Cov txheej txheej polyester feem ntau yog siv vim lawv muaj kev tiv thaiv acid zoo heev, tiv thaiv oxidation, thiab ruaj khov, khaws cia cov saj ntawm cov khoom noj mis nyuj thiab xyuas kom lawv khaws cia ntev yam tsis muaj kuab paug.
5. Cov roj (piv txwv li, cov roj noj tau, cov roj ua kom lubricating, thiab lwm yam)
Rau cov khoom siv roj, cov txheej sab hauv yuav tsum tsom mus rau kev tiv thaiv cov roj kom tsis txhob cuam tshuam nrog cov hlau, zam kev tsis zoo lossis kev ua qias tuaj. Cov txheej epoxy resin lossis polyester feem ntau siv, vim tias cov txheej no cais cov roj tawm ntawm cov hlau sab hauv ntawm lub kaus poom, ua kom ntseeg tau tias cov khoom siv roj ruaj khov thiab muaj kev nyab xeeb.
6. Cov tshuaj lom neeg los yog cov xim pleev xim
Rau cov khoom tsis yog khoom noj xws li tshuaj lom neeg lossis xim pleev, cov txheej sab hauv yuav tsum muaj kev tiv taus xeb zoo, tiv taus tshuaj lom neeg, thiab tiv taus kub siab. Cov txheej epoxy resin lossis cov txheej chlorinated polyolefin feem ntau raug xaiv, vim lawv tiv thaiv kev ua tshuaj lom neeg thiab tiv thaiv cov ntsiab lus.
Cov Lus Qhia Txog Kev Ua Haujlwm Sab Hauv:
• Tiv thaiv kev xeb: Tiv thaiv kev sib xyaw ntawm cov ntsiab lus thiab cov hlau, ua kom lub txee ntev dua.
• Kev tiv thaiv kev ua qias tuaj: Tiv thaiv kom tsis txhob muaj cov hlau tsw qab lossis lwm yam tsis zoo rau hauv cov khoom, ua kom cov saj zoo.
• Cov yam ntxwv ntawm kev kaw: Ua kom lub qhov kaw zoo dua, ua kom ntseeg tau tias cov ntsiab lus tsis raug cuam tshuam los ntawm cov yam sab nraud.
• Kev tiv thaiv oxidation: Txo qhov kev raug cov pa oxygen ntawm cov khoom, ua rau cov txheej txheem oxidation qeeb.
• Kev tiv taus cua sov: Qhov tseem ceeb tshaj plaws rau cov khoom uas tau ua tiav qhov kub siab (piv txwv li, kev tua kab mob hauv zaub mov).
Kev xaiv cov txheej sab hauv kom raug tuaj yeem ua kom muaj kev nyab xeeb thiab zoo ntawm cov khoom ntim thaum ua tau raws li cov qauv kev nyab xeeb zaub mov thiab cov kev cai ib puag ncig.
