1. Lub neej ntev npaum li cas ntawm cov galvanized coils sab laug sab nraud yog dab tsi?
Tsis muaj cov lus teb ruaj khov rau lo lus nug no, tab sis muaj ntau yam tuaj yeem muab tau. Hauv cov nroog nyob deb nroog lossis thaj chaw zoo tib yam nrog cov huab cua zoo, thiab qhov twg cov txheej txheej galvanized yog qhov ua tau zoo thiab cov tuab tuab (xws li, ob npaug -sided zinc txheej hnyav ntawm 80-100g / m²), nws lub neej ntev tuaj yeem ncav cuag 10-15 xyoo. Txawm li cas los xij, nyob rau hauv ntau qhov chaw corrosive, tus lej no yuav raug luv luv.
2. Ntau npaum li cas ib puag ncig cuam tshuam rau sab nraum zoov lifespan ntawm galvanized coils?
A: Qhov chaw ib puag ncig yog qhov tseem ceeb tshaj plaws uas txiav txim siab lub neej ntawm galvanized coils, thiab lub neej ua haujlwm txawv heev nyob ntawm ib puag ncig. Hauv thaj chaw ntub dej, los nag lossis thaj chaw uas muaj kev ua qias tuaj, lub neej yuav poob mus rau kwv yees li 8-12 xyoo. Hauv thaj chaw ntug dej hiav txwv uas muaj ntsev ntau los yog cov chaw muaj kuab paug hnyav heev, corrosion yuav nrawm heev, thiab lub neej tsuas yog 5-8 xyoo. Hauv qhov xwm txheej hnyav, yog tias raug cov pa phem heev, lossis yog tias daim ntawv galvanized nws tus kheej yog qhov tsis zoo, kev xeb loj tuaj yeem tshwm sim hauv ob peb lub hlis xwb.
3.Dhau ntawm ib puag ncig, dab tsi lwm yam tseem ceeb cuam tshuam rau nws lub neej sab nraum zoov?
Teb: Muaj peb yam tseem ceeb. Ua ntej yog zinc txheej thickness, uas yog qhov ncaj qha tiv thaiv kev tiv thaiv; zinc txheej tuab muab kev tiv thaiv ntev dua. Txawv thicknesses ntawm galvanized coils yog haum rau ntau daim ntaub ntawv. Qhov thib ob yog cov txheej txheem galvanizing thiab zoo; pluag-cov galvanized coils zoo tuaj yeem pib xeb tawm sab nraum zoov tom qab tsuas yog 1-2 xyoos, thaum cov khoom zoo muaj kev tiv thaiv zoo dua. Thaum kawg, kev puas tsuaj rau lub cev; nto khawb tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm zinc txheej, ua rau corrosion kis tau los ntawm qhov chaw puas sab hauv.
4. Yuav ua li cas cov kev hloov pauv ntawm cov galvanized coils thaum lawv tawm sab nraum zoov?
A: Qhov no yog gradual txheej txheem. Thaum xub thawj, qhov ci galvanized nto yuav maj mam tig greyish -dawb vim oxidation. Tom qab ntawd, nyob rau hauv qhov chaw ntub dej, cov xeb dawb (cov khoom siv dawb lossis grey powdery corrosion) yuav pib tshwm rau ntawm qhov chaw, ib qho kev qhia ntxov tias cov zinc txheej tau noj. Yog tias cov xeb dawb tsis raug tso tseg, cov zinc txheej yuav ua rau nyias, thiab thaum kawg, thaum cov zinc txheej tau siv tag nrho thiab poob nws qhov kev tiv thaiv rau cov hlau hauv qab, "xov liab" yuav pib tshwm sim - xeb ntawm lub hauv paus hlau- txhais tau tias cov galvanized coil tiv thaiv ua tsis tiav.
5. Cov lus pom zoo yog dab tsi yog galvanized coils yuav tsum tau muab khaws cia sab nraum zoov rau lub sijhawm ntev?
A: Thaum tsis pom zoo, yog tias kev cia sab nraum zoov tsis tuaj yeem zam tau, kev ntsuas tam sim yuav tsum tau ua kom qeeb corrosion. Npog lawv nrog tarpaulins lossis canvas los tiv thaiv tshav ntuj ncaj qha thiab los nag. Xyuas kom cov kua dej zoo thiab qhov cua ntawm qhov chaw cia, tsis txhob sib cuag nrog cov av, thiab ua kom lawv zoo dua siv cov ntoo thaiv lossis lwm yam kev txhawb nqa. Lub sij hawm cia yuav tsum tsawg; cov txheej txheem kev lag luam yog siv lawv li ntawm 3 lub hlis. Kev tshuaj xyuas tsis tu ncua yog qhov tseem ceeb, thiab txhua yam kev puas tsuaj rau lub ntim lossis cov tsos ntawm xeb dawb yuav tsum tau hais thiab kho tam sim ntawd. Ua raws li cov txheej txheem khaws cia kom zoo tuaj yeem txuas ntxiv lub neej kev pab cuam los ntawm 3-5 xyoos piv rau qhov tsis muaj kev tiv thaiv tag nrho.
