Tshaj tawm rau 2017-10-26Khoom piav qhia Junhe-8035 hlau zaj duab xis uas muaj silane muaj pes tsawg leeg, txias dov los xij, galvanized steel, aluminium, aluminium alloy, zinc alloy thiab steel pretreatment ntawm substrate nto.Cov tshuaj ntxiv no tuaj yeem hloov cov hlau ntawm hlau phosphating, zinc phosphate thiab chrome kho.Qhov no additive tsis muaj volatile khoom, nws cov hlau nto txheej adhesion thiab corrosion kuj, thiab txo cov nqi, nce productivity, thiab yuav siv tau rau txau los yog dipping txheej txheem.Cov khoom nta Green hlau zaj duab xis, tsis muaj cov khoom tsis haum, hnyav hlau ntawm NI-CR cov khoom xyaw, thiab tom qab kev kho mob tuaj yeem ua rau cov txheej txheej adhesion thiab corrosion kuj.tuaj yeem txhim kho kev tsim khoom, txo cov nqi pov tseg thiab pov tseg cov nqi pov tseg thiab lub nra ntawm ib puag ncig, thiab txo cov nqi tag nrho.Technical parameters Distribution tank deionized dej: conductivity <30μS/cm;Cl-< 10ppm Lub sij hawm ua: 3 ~ 5 feeb Lub da dej kub: chav tsev kub ~ 40 ° C tov pH nqi: 3.8 mus rau 5. 5 txheej txheem ntws 1) degrease-degreasing-pom zoo thawj ob txoj kev, xws li tsuas yog ib qho degreasing tau nce qhov concentration ntawm degreaser los yog nce qhov kub los yog ncua skim kom tau tag nrho cov roj-dawb nto yuav tsum tau kho, degreasing agents pom zoo siv cov khoom phosphate 2) kais dej - kom huv si ntxuav 3) deionized dej - conductivity yuav tsum tsawg tshaj li 200μS / cm 4) cov tshuaj silane no 5) deionized dej - hluav taws xob conductivity yog tsawg dua 30μS / cm 6) - 70 ~ 150 ℃ cua qhuav qhuav los yog tshuab qhuav da dej tswj da dej yuav tsum khaws ib tug overflow (ib lub lis piam 10%), zoo tshaj plaws sau cov tank los ntawm kev tswj lub tank hauv cov khoom xyaw nquag thiab cov kev cai sib npaug kom tau txais cov av ntxiv.Impregnated yuav tsum tau siv nrog cov dej ntws los yog tso tawm ib feem ntawm lub da dej ua ntu zus kom lub tank tshuav.Zaj duab xis no yuav tsum tau qhuav tag ua ntej pleev xim.Ua ntej electrophoresis tsis qhuav.Kev daws PH tus nqi ntsuas ntau zaus hauv ib hnub.Kev ntsuas kev ruaj ntseg PH meter PH yuav tsum tau siv cov tshuaj fluoride (inter-calibration PH 4 ~ 6.86).Kev kuaj xyuas tus qauv Kev coj ua tom qab kho rau cov ntsuas ntsuas nrog nws qhov kev txiav txim siab ntawm deionized dej conductivity PH meter PH qhov tseem ceeb tom qab kev kho, nrog nws cov ntawv xeem PH precision rau kev txiav txim siab ntawm PH tus nqi ntawm kev daws lossis kev kuaj pom (3.8-5.4 ntau), peb pom zoo. siv PH test strips test.Txheej txheej Cov kev kho mob ntawm cov khoom cuav yuav tsim cov xim hloov pauv ntawm cov xim tsis muaj xim rau xim av lossis Golden rau xiav hauv ntau qhov sib txawv.Xim nyob ntawm qhov sib txawv inorganic cov ntsiab lus hauv zaj duab xis thiab substrate ntawm cov xim sib txawv tsis qhia qhov sib txawv tseem ceeb hauv corrosion.Cia ib puag ncig Cia kub ntawm 5-45 c Yog tias cov khoom 10% nag lossis daus, muab pov tseg cov khoom siv ntim 25kg / hauv txee lub neej
