1. Dab tsi yog qhov kev xaiv tag nrho rau kev ntim khoom ntawm galvanized coils? Yuav ua li cas tiv thaiv cov kev xav tau sai sai?
Tsis muaj ib lo lus teb rau kev xaiv cov ntim ntim rau galvanized coils. Nws yuav tsum muaj kev sib txuam ua ke raws li peb qhov kev hloov pauv tseem ceeb: txoj kev thauj mus los ( hiav txwv lossis av), lub sijhawm khaws cia (luv-lub sijhawm lossis ntev-} lub sijhawm), thiab qhov chaw ntawm cov hlau coil (txawm tias txheej txheej galvanized tsis zoo).
Rau kev thauj khoom hiav txwv lossis ntev - lub sijhawm khaws cia (lub sijhawm tiv thaiv xeb ntau tshaj li rau lub hlis): Nws raug nquahu kom siv VCI vapor theem corrosion inhibitor zaj duab xis ua cov txheej sealing sab hauv, ntxiv nrog cov hlua hlau. Nws qhov txiaj ntsig yog nyob rau hauv kev muab lub sijhawm ultra- tiv thaiv xeb ntev ntawm 12 txog 24 lub hlis thiab tsis tu ncua tso xeb- tiv thaiv cov pa roj, tsim cov yeeb yaj kiab tiv thaiv ntawm txhua qhov chaw hlau hauv ib puag ncig kaw.
Rau sab hauv luv luv - kev thauj mus los los yog luv luv - lub sijhawm cia (lub sijhawm tiv thaiv xeb ntawm 1-3 lub hlis): PE stretch zaj duab xis tuaj yeem siv los ua cov txheej txheem tseem ceeb, ua ke nrog cov kaum tiv thaiv thiab cov ntaub qhwv ntoo. Qhov kev daws teeb meem no yog tus nqi qis dua thiab ua tau raws li qhov yuav tsum tau muaj kev tiv thaiv yooj yim hauv qhov chaw qhuav.
Rau cov galvanized coils: Rau cov khoom siv galvanized, nws yog ib qho tseem ceeb uas yuav tsum tau siv cov xeb tsis muaj xeb -cov ntawv tiv thaiv los yog vapor theem xeb- ntawv tshwj xeeb tsim los rau cov ntawv galvanized kom tiv thaiv qhov tsis zoo ntawm cov zinc txheej.
2.Yuav ua li cas xaiv txoj cai xeb-Kev Tiv Thaiv Daim Ntawv rau Galvanized Coil? Cov Kev Txiav Txim Siab yog dab tsi?
Xeb-kev tiv thaiv daim ntawv yog cov khoom tseem ceeb uas ncaj qha mus rau sab hauv txheej ntawm galvanized kauj. Xaiv qhov tsis ncaj ncees lawm yuav tsis tsuas yog ua tsis tiav los tiv thaiv xeb, tab sis kuj tseem tuaj yeem ua kom corrosion.
Cov khoom yuav tsum yog nruab nrab: Qhov no yog lub hauv paus ntsiab lus tseem ceeb tshaj plaws. Cov txheej txheej galvanized yog rhiab rau cov cheeb tsam acidic, yog li cov xeb zoo tib yam - tiv thaiv cov ntawv uas muaj cov kua qaub yuav tsum tsis txhob siv. Cov ntawv nruab nrab kraft lossis VCI vapor theem xeb-tiv thaiv ntawv yuav tsum raug xaiv kom tsis txhob muaj tshuaj lom neeg nrog cov zinc txheej. Tsis tas li ntawd, xeb- tiv thaiv daim ntawv tsim tshwj xeeb rau cov ntawv hlau galvanized yuav tsum tau siv, tsis yog cov tshwj xeeb rau cov ntawv txias-cov ntawv hlau lossis cov ntawv silicon steel. Hais lus nruj me ntsis, cov hom no tsis tuaj yeem sib xyaw.
3.Dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum tau xav txog thaum xaiv cov ntim rau qhov hnyav ib puag ncig xws li hiav txwv freight thiab thawv shipping?
Cov av noo siab, qhov kub thiab txias sib txawv, thiab cov ntsev ntsev ntau nyob rau hauv hiav txwv freight thiab ntim khoom ua rau muaj kev pheej hmoo ntawm oxidation thiab xeb ntawm galvanized coils. Kev xaiv ntim yuav tsum tau txais kev sib xyaw ua ke kom nruj dua.
Qhov zoo dua, VCI (Vacuum Phase Inhibitor) thev naus laus zis yog qhov zoo dua: Hauv lub thawv kaw, VCI zaj duab xis lossis xeb - ntawv tiv thaiv yog riam phom tseem ceeb. Nws tsis tu ncua tso xeb-cov pa tiv thaiv, uas tuaj yeem nqus mus rau txhua qhov chaw hlau hauv qhov chaw kaw, suav nrog nyuaj - mus rau - mus txog thaj chaw xws li cov tub ntxhais coil thiab cov npoo, tsim cov nano - qib tiv thaiv txheej rau kev tiv thaiv kev tiv thaiv. Qhov no tso cai rau cov roj- ntim khoom pub dawb, zam qhov tsis txaus siab degreasing thiab ua haujlwm tom qab ntxuav, txuag lub sijhawm thiab khaws cov nqi tswj hwm.
Siv ntau- txheej ntim: Ib zaj duab xis feem ntau tsis txaus. Cov qauv ntim khoom xa tawm kom zoo feem ntau muaj xws li: txheej txheej ntawm VCI zaj duab xis / xeb- cov ntawv tiv thaiv, ib txheej txheej ntawm cov khoom ntim tsis muaj dej tsis zoo xws li cov ntaub npuag lossis cov ntawv hlau, thiab thaum kawg, kev txhawb nqa nrog cov hlua hlau. Nyob rau tib lub sijhawm, tus nqi txaus ntawm silica gel desiccant yuav tsum tau muab tso rau hauv lub ntim ntim nrog qhov khoob kom nquag nqus cov dej seem.
4. Dab tsi yog cov ntsiab lus tseem ceeb hauv kev ua tiav cov ntim ntim? Yuav ua li cas thiaj li muaj peev xwm txhawb nqa lub cev thiab kev sib khi kom ruaj khov?
Tom qab kev xaiv ntim tau txiav txim siab, qhov kev ua tiav yog cov kauj ruam kawg uas txiav txim siab qhov ua tiav lossis tsis ua tiav ntawm kev tiv thaiv. Lub hom phiaj tseem ceeb ntawm kev ntim khoom ntim yog tsim kom muaj "microenvironment" uas cais qhov chaw sab nraud, uas yuav tsum muaj kev sib koom tes ntawm kev txhawb nqa lub cev thiab kev sib khi tshuab.
Kev txhawb nqa lub cev yog qhov tseem ceeb: Thaum siv cov thawv ntim khoom sab nrauv, xaiv cov vaj huam sib luag nrog lub thickness ntawm 0.4-0.6 hli los yog cov yas panels nrog lub thickness ntawm 1.2-1.4 hli, thiab nteg lawv rau ntawm lub thawv ntim khoom (tso los ntawm ob lub thawv ntoo nrog qhov sib txawv ntawm qhov dav ntawm cov hlau kauj). Thaum tso PVC yas zaj duab xis txheej, xyuas kom meej tias cov khoom tsis zoo, tiaj tus, tsis muaj kev puas tsuaj thiab wrinkles; qhov pom zoo sib tshooj yog nruab nrab ntawm 100 thiab 300 mm.
Tsim kom muaj kev sib khi nruj hauv thiab sab nraud: Tom qab ua tiav cov kev txhawb nqa lub cev, pib tso cov xeb- cov ntaub ntawv pov thawj. Coated sab ntawm xeb- ntawv tiv thaiv yuav tsum muab tso rau sab saud, nruj nreem sib tshooj ntawm cov ntawv tseem ceeb. Qhov dav ntawm cov ntawv tseem ceeb yuav tsum yog kwv yees li 0-60 hli tsawg dua qhov dav ntawm cov hlau yob, thiab nws yuav tsum tau muab kaw tag nrog daim kab xev. Tom qab ntawd, qhwv daim ntawv tiv thaiv xeb nce mus raws qhov ncig ntawm cov hlau yob, xyuas kom muaj kev sib tshooj ntawm 50 hli nrog cov ntawv tseem ceeb thiab tsawg kawg 100 hli ntawm nws tus kheej sib tshooj. Tag nrho cov seams thiab qhov kawg creases yuav tsum tau muab khi kom ruaj ntseg nrog daim kab xev nplaum kom ntseeg tau tias muaj qhov sib khi tag nrho. Daim kab xev siv rau txhua qhov sib tshooj yuav tsum yog qhov dav txaus thiab ruaj khov.
5. Dab tsi yog cov kev cai tshwj xeeb thiab cov qauv rau kev xa tawm hiav txwv freight ntim?
Rau exported galvanized coils, ntim ntim yuav tsum tsis tsuas yog xeb- pov thawj tab sis kuj ua raws li cov kev cai thoob ntiaj teb kev lag luam.
**Definition of Packaging Grade:** Raws li kev thauj mus los thiab kev sib txawv ntawm ib puag ncig, cov qib ntim khoom siv feem ntau yog cov ntim khoom zoo (lossis siab - ntim zoo). Hom ntim no muaj cov txheej txheem sealing sab hauv thiab feem ntau tsim nyog rau cov khoom xa los ntawm hiav txwv mus rau siab - kub thiab siab - thaj chaw av nyob rau sab qab teb, nrog rau siab - cov khoom lag luam rau cov neeg siv khoom tseem ceeb.
**Kev Ua Raws Cai:** Kev ntim ntim ntim yuav tsum ua raws li lub teb chaws xeb tam sim no - cov qauv ntim pov thawj (xws li GB/T 4879-2016) kom ntseeg tau tias cov khoom ntsuas (xws li noo noo permeability) ua tau raws li cov kev cai.
** Cov Ntaub Ntawv Qhia Txog Kev Sau Npe: ** Qhov kawg ntim ntim yuav tsum kom meej thiab ruaj khov sau cov npe khoom, cov lus qhia tshwj xeeb, txheej hnyav, batch naj npawb, net hnyav thiab hnyav hnyav, chaw tsim khoom lub npe, hnub tsim khoom, qhov chaw, thiab tsim nyog "waterproof thiab noo- pov thawj" thiab khaws cia thiab cov cim kev thauj mus los.
