1.What yog qhov tseem ceeb vim li cas rau cov xim txawv ntawm cov txheej xim?
Cov khoom siv nyoos hloov: xim hloov ntawm cov xim xim batches, xws li roughness thiab phosphote txheej uniformity kev sib txawv los yog sib piv.
Kev tsis ncaj ncees Pretreatment: Tsis tiav kev ua tiav thiab tsis sib xws phosphate txheej tuab hauv thaj chaw) ua rau muaj kev hloov pauv hauv cov xim nplaum thiab qib siab.
Hloov pauv nyob rau hauv cov txheej txheem txheej txheej: Uneven Txheej Txheej (xws li hnav cov menyuam thiab tsis txaus), thiab tsis muaj xim pleev xim rau (xim xim).
Tsis ruaj khov qhuav thiab kho tej yam kev mob: kev faib tawm tsis sib xws nyob rau hauv qhov cub kom sov (hauv zos overheating los yog unconsentent tu sij hawm ua rau variations nyob rau hauv cov tshuaj kho tau ntawm cov xim.
Ib puag ncig thiab kev sim ib puag ncig: kev hloov pauv hauv cov khw muag khoom kub, xws li lub teeb pom kev zoo teeb tsa), thiab Codyimeter Calibration ua tsis tiav.
2.What cuam tshuam kev tswj hwm ntawm cov xim tha xim muaj rau xim sib txawv?
Thawj cov xim pleev xim los ntawm tib pawg, thiab hais kom meej "tib yam kev txiav txim, tib qho kev sib tw" thaum tso ib qho kev txiav txim. Yog tias qhov kev hloov pauv tsis tsim nyog, kev coj ua ib qho kev ntsuas sib piv ua ntej. Cov khoom tshiab thiab qub ntawm cov xim tha xim yuav tsum tau thov rau tib lub substrate siv cov txheej txheem qub. Cov xim sib txawv (ENE tus nqi, feem ntau ΔE tsawg dua lossis sib npaug rau 1.5) yuav tsum ntsuas ua ntej siv.
Ua ntej cia, cov xim yuav tsum tau kuaj rau xim ruaj khov: Siv tus qauv rau kev ntsuas cov xim ntawm cov qauv xim (piv rau cov qauv khoom siv Hoobkas). Tsis tas li, kos rau stratification thiab sedimentation. Yog tias muaj, kom huv si kom txog thaum khaub ncaws hnav. Lub sijhawm stirringing sib txawv raws nyob ntawm seb hom xim tha xim; Piv txwv li, daws -} xim yuav tsum muaj 30-60 feeb.
3.Txhua qhov chaw ntawm lub ntsej muag li cas?
Substrates (xws li txias - rolled thiab galvanized steel) yuav tsum muaj kev sib daj sib xws (feem ntau ra {1} μm). Thaum khaws cia, qauv txheej txheem substrate yuav tsum tau tshuaj xyuas kom tsis txhob muaj kev tsis txaus siab ntawm cov menyuam yaus lub cev (xws li cov menyuam cim thiab oxidation me ntsis).
Yog tias yuav tsum tau kho phosphate yog qhov yuav tsum tau ua, phosphate zaj duab xis thickness (feem ntau 5-10μm) thiab kev sib koom ua ke yuav tsum tau tswj hwm. Qhov no tau ua tiav los ntawm kev ua kom muaj kev ruaj ntseg ntawm cov tshuaj phaosphate (piv txwv li acidity, free acidity), kub (40-30 degree), thiab lub sijhawm kho (1-3 feeb). Yuav tsum ua cov kev xeem tsis tu ncua yuav tsum tau ua kom tau txais kev pab them rau ntsev (piv txwv li tooj liab sulfate poob kuaj ntsuas tsis muaj cov pob liab tsis pub dhau 30 feeb).
4.Qhov kom zam dhau "tsis sib haum xeeb hauv cov theem tom qab" thaum lub sijhawm tsheb thauj mus los?
Txawm hais tias cov xim sib txawv thaum lub sijhawm tsim khoom siv tau, tsis raug cai cia thiab tsheb thauj tuaj yeem ua rau "tom qab cov laus lossis kev sib kis hauv zos):
Khaws cov panels upright (zam kev sib xyaws, uas tuaj yeem ua rau cov txheej txheej kom ua raws li lub siab). Siv spacers (xws li kraft ntawv) ntawm panels kom tiv thaiv kev sib txhuam ua rau cov txheej.
Khaws rau hauv ib qho qhuav, zoo - ventatated av qeeg (xws li lub teeb ci ntsa iab (xws li ntawm cov pa roj av (xws li cov pa roj av (}} pa roj ntsha
Thaum lub sij hawm thauj mus los, npog nrog tarpaulin (kom tsis txhob muaj nag), tswj hwm kev sib tsoo (kom tsis txhob muaj kev sib tsoo thiab tsis kam ua rau cov txheej txheem dej kev nqus thiab tshem tawm).
5.Qhov yog tus "tub ntxhais tseem ceeb" ntawm kev tswj hwm xim sib txawv?
Lub hauv paus ua rau cov xim sib txawv nyob rau hauv pre -}} Painted cov khoom yog qhov tsis muaj kev sib xws thoob plaws tag nrho cov txheej txheem. Tus yuam sij rau kev tswj cov xim sib txawv lus dag nyob rau hauv tshem tawm cov hloov pauv ntawm txhua theem, los ntawm cov khoom raw rau cov khoom tiav. Qhov no yog tiav los ntawm cov ntaub ntawv raw ua qauv, cov khoom siv kub (txheej kub), sov cov khoom siv thiab cov duab ua kom sov (online filmes ghaunes, codimeter). Qhov no tsim ib lub voj kaw ntawm "Kev Tiv Thaiv {{5} - hloov kho." Tsis tas li ntawd, cov ua haujlwm cov kev ua haujlwm yuav tsum muaj zog (xws li kev kawm hloov kho ntawm txhua theem kom paub tseeb zam kev sib txawv.
