1.How kom tshem tawm cov nplaim loj?
Residual Roj (Rolling roj), cov khoom tshauv (hmoov av (zinc oxidation cov khoom lag luam tuaj yeem ua rau "tsis tseeb adches" (ib feem ua tsis tiav ntawm cov txheej txheem). Yuav tsum muaj ntau -} theem ntxuav ua: Ua ntej, tshuaj tsuag lossis soak nrog cov alkaline hydroxide daws, 1 {}}}} pa 3%) kom tshem tawm cov roj; Tom qab ntawd yaug nrog lub dav hlau dej siab (0.3-0.5 mpa) kom tshem tawm cov khoom seem degrecase; Thiab thaum kawg, yaug nrog dej de deionized (kev ua haujlwm tsawg dua lossis sib npaug los tiv thaiv cov dej paug hauv dej (xws li cov calcium thiab tsim cov pob nyob saum npoo.
2.Qhov kom tswj hwm lub xeev saum npoo ntawm zinc txheej?
Cov txheej zinc txheej yuav tsum muaj kev sib txawv (tuab strorkiation tsawg dua los yog sib npaug ntawm qhov ploj plating thiab zinc cov ntsiab lus tuaj yeem ua rau cov txheej tsis sib xws ntawm cov txheej tsis sib xws los yog txawm tias tawg. Yog tias cov txheej zinc txheej yog oxidized thiab blackened (vim yog ib qho kev kho kom huv si (xws li ua ntej kev kho kom zoo nkauj
3. Vim li cas peb yuav tsum ua kom muaj kev ntxhib ntxoo qhov dav?
Ib qho chaw zinc du tsis muaj peev xwm ua kom cov xim nplaum, thiab "microschaate) muaj tseeb: thaum lub ntsej muag phos tshuaj" Cov hws ntawm lub muaju tso cai pleev xim rau "embed", tseem ceeb txhim kho adhesion; Passivation (xws li chromate passivation) cov ntaub ntawv ntom nti ua yeeb yam ntawm zinc txheej, tab sis kuj tseem sib xyaw nrog cov txheej txheem los ntawm kev kos duab tshuaj.
4.How kom phim xim uas yog xim?
Rau cov ntawv thov sab nraum zoov (xws li phab ntsa kab hlau): Xaiv huab cua {{0} {{ruicone} {hloov cov txheej txheem polyester). Fluorocarbon Txheej fluorine atoms, uas muaj kev siv tshuaj lom neeg muaj zog rau UV kev laus thiab cov kua sab nraum zoov (nrog rau sab nraum zoov (nrog rau sab nraum zoov Silicon -}}}} Recified polyester txheej muaj ntau dua tus nqi ntau dua (nrog lub neej ntawm 10-15 xyoo). Xyuas kom meej tias muaj ntau npaum li cas ntawm cov huab cua sib ntxiv (xws li UV nqus) ntxiv rau txheej txheej sib ntsib cov kev cai tswj hwm (feem ntau 1-3%).
Rau cov ntawv thov muaj kev lag luam (xws li cov cuab yeej siv thiab cov khoom siv high - cov roj nplaum thiab cov txheej txheem polyester (epoxy txheej). Epoxy Primers muaj cov adhesion muaj zog (hla}} Txiav kev sib tw ntau dua lossis sib npaug nrog cov kab mob polyester), rau ob qho kev tiv thaiv corrosion thiab loog. Rau cov ntawv thov cuam tshuam nrog cov khoom siv roj hmab (xws li chav ua noj ua noj), xaiv roj - cov txheej ntau (xws li polyurethane coacings). Cov xwm txheej tshwj xeeb (xws li cov nroj tsuag tshuaj thiab cov ntug dej hiav txwv) - Xaiv cov ntaub acid thiab muaj peev xwm tiv taus cov pa roj ntsha thiab muaj peev xwm tiv taus cov kua qaub thiab cov pa roj qaub thiab muaj peev xwm tiv taus cov pa roj ntsha Tom qab kev ntsuas ntsev (500 teev), txheej yuav tsis tawg lossis xeb.
5.How kom cov txheej ruaj khov?
Ua ntej siv, cov xim yuav tsum tau ua kom meej stirred (kom tsis txhob muaj xim sib deev) thiab cov tshuaj tua kab: me ntsis viscosity rau cov txheej txheej cov khoom, me ntsis qis rau txau). Ntau ntau hom viscosity siab yuav ua rau cov txheej tuab thiab tsis muaj peev xwm tsawg, thaum cov txheej av tsis muaj zog tsawg yuav ua rau sagging (txheej yuav yuag dhau hauv qee thaj chaw). Yog tias cov xim tau khaws cia rau ntev dhau (tshaj nws lub txee lub neej), nws muaj txiaj ntsig (tsawg dua lossis sib npaug lossis sib npaug); Yog tias tsis muaj qhov tsim nyog, nws txwv tsis pub siv.
