1.How los ntxuav thiab tiv thaiv hauv lub neej txhua hnub?
Saib
Kev tu kom huv: ntxuav tsawg kawg ib hlis ib zaug, nyob ntawm kev siv ib puag ncig (piv txwv li tu, ntau zaus tu hauv ib puag ncig noo thiab plua plav ib puag ncig).
Kev Tu Txoj Kev: Siv daim ntaub mos muag lossis txhuam kom tshem cov hmoov av thiab av los ntawm qhov chaw. Zam txhob siv cov cuab yeej nyuaj xws li cov ntaub plaub hlau los tiv thaiv kom tsis txhob khawb cov galvangized txheej.
Yog tias muaj cov roj stains lossis tawv ncauj stains ntawm saum npoo, dilute nws nrog cov tshuaj ntxuav tais diav (xws li ntxuav tais diav ua kua) thiab so yaug nrog dej huv thiab ntxuav kom qhuav.
Ceev faj: Zam kev siv cov kua qaub lossis cov tshuaj ntxuav tes (xws li cov tshuaj alkaline, muaj zog alkaline) kom tsis txhob xeb ntawm cov galvanized txheej.
2.What yog cov dej noo thiab kev ntsuas xeb?
Kev tswj hwm ib puag ncig: tsis txhob muaj ib puag ncig lim dej ntev (xws li sab nraum zoov stacking) thaum lub sijhawm cia lossis siv. Yog tias nws yuav tsum tau khaws cia sab nraum zoov, npog nws nrog cov ntaub ntub dej thiab ua kom cov av hauv qab (ntoo ntoo lossis cov pob zeb tuaj yeem siv ua cov ntaub qhwv).
Hauv zos tiv thaiv xeb:
Yog hais tias lub galvanized txheej yog puas (xws li khawb lossis xeb siv xeb kom tsis txhob muaj xeb kom tsis txhob xeb.
Nquag xyuas cov corrosion-prone seem xws li vuam cov ntsiab lus thiab txiav. Yog tias muaj cov cim ntawm xeb, kho lawv raws li cov qauv saum toj no.
3.Txheb ib puag ncig kub li cas?
Yog tias lub galvanized square raj yog siv nyob rau hauv ib puag ncig kub siab (xws li ib puag ncig muaj kev muaj cua sov),
Nco tseg:
Zam kom tsis txhob raug ncua ntev mus rau qhov siab siab tshaj 300 qib degree los tiv thaiv cov galvangized txheej los ntawm oxidizing thiab poob tawm.
Nquag tshuaj xyuas seb cov galvanized txheej nyob rau hauv qhov chaw kub siab tau hloov xim lossis tev tawm. Yog tias nws tau poob tawm, nws yuav tsum tau rov ua kom sov nrog kub tiv taus cov xim (xws li cov xim tsis txaus siab) nyob rau lub sijhawm.
4.How tswj kom muaj kev mob ib puag ncig kev xeb?
Nyob rau hauv cov kev sib zog corrosive heev xws li kev cob qhia tshuaj lom neeg thiab dej hiav txwv siab ntsev pos huab:
Nce tu cov zaus (ib hlis ib zaug) thiab yaug qhov chaw ntsev lossis tshuaj tsis txaus nrog dej huv.
Epoxy Resin Xim lossis Polyureaa Txheej tuaj yeem siv rau sab nraum lub galvanized txheej kom txhim kho kev tiv thaiv corrosion.
Txo cov voj voog soj ntsuam (ib hlis ib zaug) thiab tsom mus rau cov seem mus rau corrosion.
5.Txhua nyob sab nraum zoov ib puag ncig?
Square tubes siv sab nraum zoov rau lub sijhawm ntev (xws li tus zov me nyuam, thav duab sab nraum zoov):
Txheeb xyuas cov kev ncaj ncees ntawm cov txheej galvanized ib xyoos ib zaug thiab kho cov hlau loj hauv lub sijhawm. ◦
Acid los nag yog nquag nyob hauv thaj chaw, thiab cov saum npoo yuav tsum tau ntxuav kom huv rau lub sijhawm tom qab los nag los txo cov kua qaub acid.
