Q: Puas yog tus nqi tu txhua hnub ntawm cov xim galvanized-coated coils siab?
A: Tsis siab. Cov nqi tu txhua hnub yog qhov tsawg, ua rau nws yog txoj hauv kev zoo tshaj plaws los tswj cov nqi tag nrho thiab tus nqi ntau tshaj - kev nqis peev zoo.
Kev saib xyuas txhua hnub feem ntau yog hais txog kev tu lub sijhawm thiab tshuaj xyuas. Cov nqi yog feem ntau hauv kev ua haujlwm thiab cov khoom siv:
Tus nqi tu: xam los ntawm cheeb tsam, tus nqi feem ntau yog 2-5 yuan / sq.
Tus kheej-Kev Tu: Kev lag luam ntau dua. Txhua rau lub hlis, siv rab phom dej siab - los ntxuav cov plua plav zoo tib yam, lossis so cov roj stains nrog cov tshuaj ntxuav tes thiab cov ntaub mos muag.
Rov qab los ntawm Kev Lag Luam: Qhov kev nqis peev me me no tau txais txiaj ntsig zoo. Kev tu tsis tu ncua tuaj yeem ua rau qeeb ntawm cov txheej txheem kev laus ntawm kev tsim cov phab ntsa sab nrauv los ntawm ntau dua 30%.
Q: Dhau li ntawm kev tu, puas muaj lwm cov nqi tu?
A: Yog lawm, feem ntau yog kho thiab hloov kho hauv zos. Cov no yog cov nuj nqis tseem ceeb rau kev daws teeb meem.
Yog tias muaj teeb meem loj dua, cov nqi tu yuav nce ntxiv:
Tus nqi kho hauv zos: 50-100 yuan ib square meter, tsim nyog rau kev kho cov khawb me me, kev puas tsuaj, lossis hloov cov vaj huam sib luag ntawm tus kheej.
Ua kom tiav tus nqi kho dua tshiab: 5-50 yuan ib square meter, thaum txheej txheej muaj hnub nyoog dhau ntawm thaj chaw loj thiab cuam tshuam rau qhov tsos, yuav tsum tau ua kom tiav repaint.
"Hidden" cov nqi siab: Hauv cov chaw tsim khoom thiab lwm qhov chaw, thaum muaj teeb meem loj zuj zus tuaj thiab xav tau kev kho lossis hloov pauv, cov khoom poob los ntawm kev poob qis tuaj yeem tshaj tus nqi ntawm cov ntaub ntawv lawv tus kheej.
Q: Vim li cas qee tus neeg hais tias nws cov nqi kho mob siab, thaum lwm tus hais tias lawv qis?
A: Qhov no yog qhov sib txawv ntawm cov ntsiab lus ntawm "passive maintenance" thiab "proactive care," thiab kuj muaj qhov sib txawv ntawm qhov zoo ntawm cov khoom nws tus kheej.
"Kev saib xyuas tsis tu ncua": Vim yog kev xaiv cov khoom siv tsis raug lossis tsis saib xyuas kev saib xyuas, cov txheej yuav tev tawm tom qab li ob xyoos, yuam kev nqis peev loj hauv kev kho.
"Kev saib xyuas tsis tu ncua": Los ntawm kev xaiv cov khoom zoo- thiab ua haujlwm tsis tu ncua, tsuas yog xav tau kev nqis peev me me tom qab, ua tiav 5-8 xyoo lossis ntev dua yam tsis muaj kev kho loj, ua rau cov nqi qis dua.
Cov khoom zoo: kev xaiv cov khoom yog qhov tseem ceeb. Piv txwv li, siv cov zinc siab heev- txhuas- magnesium txheej, nws cov khoom "tus kheej- kho" tuaj yeem txuag tau nyiaj ntau ntawm cov nqi tu.
Q: Puas yog kev saib xyuas tus nqi sib txawv nyob ntawm ib puag ncig?
A: Qhov tseem ceeb heev. Ib puag ncig yog qhov tseem ceeb ntawm kev txiav txim siab qhov zaus thiab tus nqi ntawm kev saib xyuas.
Kev faib tawm ib puag ncig|Tus nqi tu|Kev piav qhia
Ib puag ncig ib puag ncig (piv txwv li, thaj chaw nyob deb nroog, cov nroog dav dav)|Tsawg|Kev tu ib xyoos ib zaug lossis tsawg dua, txheej txheej txheej yog txaus, cov nqi ruaj khov thiab tswj tau.
Cov cheeb tsam muaj kuab paug (xws li, steel mills, fais fab nroj tsuag, chiv chiv)|Siab|Cov tshuaj acidic thiab alkaline ua kom muaj zog corrosion, yuav tsum tau ua haujlwm tu ntau zaus, thiab txawm tias tshwj xeeb corrosion- cov coatings resistant.
Ntug Dej Hiav Txwv Txau Siab|Siab heev|Cov tshuaj tsuag ntsev yog corrosive heev, yuav tsum tau ntxuav phau ntawv 1-2 zaug hauv ib xyoos. Corrosion-cov khoom tiv taus xws li zinc-aluminium-magnesium coatings yuav tsum raug xaiv los txo cov nqi tu mus sij hawm ntev.
Q: Yog li, peb yuav ua li cas thiaj li txo tau tag nrho cov nqi tu hauv lub sijhawm ntev?
A: Qhov tseem ceeb yog "xaiv cov khoom tsim nyog ua ntej thiab ua qhov zoo tom qab." Ua raws li cov hauv paus ntsiab lus no yuav tswj tau cov nqi zoo:
** Xaiv cov ntaub ntawv raws li ib puag ncig: ** Qhov no yog qhov tseem ceeb. Rau ib puag ncig corrosive, ua qhov tseem ceeb zinc- txhuas-magnesium plating lossis fluorocarbon (PVDF) txheej. Rau ib puag ncig muaj kuab heev, xaiv tus kheej- ntxuav cov txheej txheem kom txo tau qhov zaus ntawm kev ntxuav.
**Xaiv siab- cov khoom zoo:** Txawm hais tias tus nqi pib yog siab dua, kev pabcuam lub neej ntev dua. Cov ntaub ntawv qhia tau hais tias tus nqi nruab nrab ntawm kev ua haujlwm siab ntawm - cov khoom zoo yog qis dua li cov hlau zoo tib yam.
** Tsim kom muaj ib txoj kev npaj saib xyuas:** Tsim ib qho kev tshuaj ntsuam xyuas thiab tu cov phiaj xwm tsis tu ncua los daws cov teeb meem me sai sai thiab zam kev kho tus nqi siab -.
** Kev tiv thaiv kev tsim kho kom zoo: ** Xyuas kom tseeb tias qhov kev txiav thiab khawb raug kaw thaum lub sijhawm teeb tsa kom tshem tawm cov ntsiab lus tsis muaj zog uas cuam tshuam rau corrosion.
