1.Dab tsi yog lub voj voog kev xeem?
Ua ntej-khiav Kev Tshawb Fawb/Pib- nce Kev Tshuaj Xyuas
Lub Sijhawm: Thaum cov kab txuas txuas ntxiv galvanizing hloov cov qib steel, zinc da dej muaj pes tsawg leeg, lossis rov pib dua tom qab kaw ntev, thawj kauj lossis thawj ob peb coils tsim yuav tsum tau kuaj zinc txheej purity.
Lub Hom Phiaj: Los xyuas kom meej tias cov txheej txheem ntau lawm (xws li zinc da dej kub, cov ntsiab lus txhuas, tus nqi cua txias, thiab lwm yam) raug teeb tsa kom raug thiab cov zinc txheej muaj pes tsawg leeg tseem nyob ruaj khov hauv lub hom phiaj.
Periodic/Batch Inspection
Lub voj voog: Rau kev ruaj khov, tsis tu ncua ntau lawm, kev sim feem ntau ua ib zaug ua haujlwm, txhua hnub, lossis ib pawg.
Piv txwv:
Cov hlau loj loj tuaj yeem hais qhia "sampling ib zaug ib zaug" lossis "sampling ib zaug txhua 500 tons."
Qhov no nyob ntawm lub tuam txhab kev tswj cov ntaub ntawv thiab kev pom zoo nrog cov neeg siv khoom.
Txhim khu kev soj ntsuam nyob rau hauv cov xwm txheej txawv txav
Sijhawm: Thaum pom qhov txawv txav ntawm zinc txheej adhesion los yog ntog (xws li zinc paj loj thiab gloss), qhov kev tshuaj xyuas zaus yuav nce tam sim ntawd, txawm tias mus rau qhov chaw tshuaj xyuas txhua yob, kom txog rau thaum lub hauv paus ntawm qhov teeb meem pom thiab daws tau.
Lub Hom Phiaj: Txhawm rau kuaj xyuas cov teeb meem sai sai thiab tiv thaiv kev tsim khoom ntau ntawm cov khoom puas.
2.Vim li cas ho tsis siab -ntau zaus kuaj?
Kev kuaj kev puas tsuaj: Kev txiav txim siab zinc plating purity (feem ntau yog cov qauv thiab muaj pes tsawg leeg ntawm cov hlau-zinc alloy txheej) feem ntau yuav tsum tau npaj cov qauv metallographic. Qhov no suav nrog kev coj mus kuaj los ntawm cov hlau coils, txiav, txuas, sib tsoo, polishing, thiab etching lawv, ua raws li kev soj ntsuam thiab kev soj ntsuam hauv qab lub tshuab ntsuas hluav taws xob (SEM) thiab lub zog-dispersive X-ray spectroscopy (EDS). Qhov no yog kev puas tsuaj, sijhawm -siv, thiab raug nqi ntau.
Txheej Txheem Parameter Saib Xyuas Lwm Txoj Haujlwm: Hauv kev tsim cov galvanizing niaj hnub no, purity feem ntau ua kom ntseeg tau los ntawm kev tswj hwm nruj ntawm cov txheej txheem, xws li:
Zinc da dej kub: nruj me ntsis tswj nyob rau hauv ± 2 degree.
Cov ntsiab lus ntawm txhuas: nruj me ntsis tswj cov ntsiab lus txhuas hauv zinc da dej los ntawm kev sojntsuam hauv online lossis tshuaj ntsuam xyuas ib ntus (rau GA ntshiab zinc, cov ntsiab lus txhuas tsis tshua muaj siab; rau GL, txhuas cov ntsiab lus yog nyob ib ncig ntawm 0.2%).
Lub sijhawm immersion thiab txias npaum li cas.
Ntev npaum li cov ntsiab lus tseem ceeb no ruaj khov, purity ntawm zinc plating txheej yog suav tias yog ruaj khov.
3.Dab tsi yog qee qhov kev xeem uas muaj feem cuam tshuam?
Txoj kev: Online X-ray fluorescence thickness gauge tau siv.
Zaus: Tiag -lub sij hawm, nruam scanning raws qhov dav thiab ntev ntawm steel kauj.
Qhov tseem ceeb: Qhov hnyav ntawm zinc txheej ncaj qha cuam tshuam rau cov khoom lag luam corrosion kuj thiab cov nqi tsim khoom, ua rau nws yog ib qho tseem ceeb tshaj plaws rau cov neeg siv khoom. Yog li ntawd, nws qhov kev xeem qhov tseem ceeb thiab zaus yog siab dua qhov kev kuaj purity.
4.Dab tsi yog lub sij hawm mus sij hawm rau zinc txheej purity kuaj?
Tsawg zaus (ib ua haujlwm, txhua hnub, lossis lub sijhawm txawv txav)
5.Dab tsi yog qee yam uas yuav tsum nco ntsoov?
Internal Quality Control: Yog tias koj yog cov chaw tsim khoom, nws raug nquahu kom suav nrog zinc txheej purity kuaj hauv koj lub tuam txhab Txoj Kev Tswj Xyuas Zoo. Qhov no tuaj yeem txhais tau tias yog kev ntsuam xyuas txhua hnub ntawm thawj kauj lossis kev sim tom qab txhua pawg ntawm zinc pot muaj pes tsawg leeg hloov pauv, nrog cov lus qhia meej rau kev ntsuas nruj dua thaum cov txheej txheem tsis hloov pauv ntau.
Supplier Management: Yog tias koj yog tus neeg yuav khoom, koj tuaj yeem xav kom cov neeg muag khoom muab cov hauv qab no hauv kev pom zoo:
Tsis tu ncua (piv txwv li, peb lub hlis twg los yog batch-los ntawm-batch) tso cai thib peb-cov ntaub ntawv kuaj xyuas tog.
Lawv cov ntaub ntawv tswj xyuas zoo thiab cov ntaub ntawv hais txog zinc txheej purity.
Qhov tseem ceeb tshaj, xyuam xim rau lawv cov ntawv pov thawj ntawm zinc txheej hnyav ua raws li txhua kauj ntawm cov khoom.
