Q: Hom vov tsev twg yuav tsum tau siv nrog cov xim galvanized-coated steel nag gutters?
A: Nws raug nquahu kom ua qhov tseem ceeb ntawm cov xim -coated ru tsev panels nrog tib lub substrate (xws li, kub-dip galvanized steel ntawv) thiab cov txheej txheem txheej zoo sib xws (piv txwv li, polyester, silicone- hloov polyester, lossis fluorocarbon txheej) raws li cov nag gutters. Qhov no ua kom cov coefficient zoo sib xws ntawm thermal expansion thiab contraction, txo deformation los yog tawg los ntawm kev hloov kub; tib lub sijhawm, cov txheej txheem muaj cov huab cua tsis sib haum, tsis txhob muaj qhov sib txawv ntawm cov xim lossis cov xim corrosion tom qab siv sijhawm ntev -.
Q: Yuav ua li cas xaiv cov xim sib txuam ntawm lub gutter thiab lub ru tsev vaj huam sib luag?
A: Muaj ob txoj hauv kev zoo sib xws. Ua ntej, ib txoj hauv kev monochromatic: siv cov xim tib yam li lub ru tsev vaj huam sib luag tsim kom muaj kev sib koom ua ke pom, haum rau cov qauv vaj tsev uas hais txog kev yooj yim thiab kev sib xws. Qhov thib ob, ib qho xim xim zoo nkauj: siv dawb, grey tsaus, lossis tsaus nti - xim gutter uas sib piv nrog lub ru tsev xim xim tseem ceeb rau cov kab ntawm eaves. Txawm li cas los xij, nws yuav tsum tau muab sau tseg tias qhov tsaus ntuj - cov kab txaij xim tuaj yeem ua kom sov sai dua hauv thaj chaw uas muaj hnub ci zog; Nws raug nquahu kom xaiv cov txheej txheej nrog cov cua sov zoo dua. Nws tsis pom zoo kom siv cov xim uas sib tsoo nrog lub ru tsev (piv txwv li, liab ru tsev vaj huam sib luag nrog ntsuab gutter).
Q: Yuav ua li cas sib tshooj ntev thiab sealing txoj kev ntawm galvanized xim -coated steel rainwater gutters?
A: Qhov sib tshooj ntev ntawm ob ntu ntawm lub qhov dej nag hauv qhov kev taw qhia ntawm cov dej ntws yuav tsum tsis pub tsawg dua 100 hli, thiab sab saud yuav tsum npog rau sab nrauv ntawm sab qis (hauv kev taw qhia ntawm cov dej ntws). It is recommended to use a neutral weather-resistant sealant (such as silicone sealant) to fill the joint, and install a waterproof strip of color-coated steel sheet with a width of not less than 50 mm on the outside, securing it with rivets every 150-200 mm. Nws yog nruj me ntsis txwv tsis pub cia siab rau ib leeg ntawm sealant yam tsis muaj kev kho tshuab, txwv tsis pub nws yuav yooj yim tshem tawm vim thermal expansion thiab contraction.
Q: Cov ntaub ntawv dab tsi yuav tsum tau siv rau cov brackets thiab screws siv los kho cov kav dej nag?
A: Corrosion-resistant fasteners uas muaj peev xwm zoo ib yam li cov galvanized steel kauj yuav tsum tau siv. Kub-dip galvanized steel brackets lossis 304 stainless hlau brackets raug pom zoo. Screws yuav tsum yog stainless hlau tus kheej-tapping screws nrog EPDM roj hmab washers los yog kub-dip galvanized screws. Ordinary hlau los yog electroplated galvanized qhov chaw yog nruj me ntsis txwv tsis pub, raws li cov zinc txheej yog nyias thiab yooj yim rusts. Rusting yuav ua rau electrochemical corrosion ntawm cov npoo ntawm cov hlau kauj, nws thiaj li xeb los ntawm tag nrho cov gutter los ntawm kho qhov.
Q: Dab tsi yog cov ntsiab lus tseem ceeb uas yuav tsum nco ntsoov thaum txuas lub gutter mus rau ib qho downpipe?
A: Ua ntej, qhov qhib qhov loj me ntawm cov kav dej txuas txuas yuav tsum phim qhov dav thiab cov duab ntawm lub qhov dej (feem ntau K-hom lossis ib nrab- lub voj voog gutters). Qhov qhib yuav tsum nyob rau ntawm qhov chaw qis tshaj ntawm lub gutter thiab me ntsis hauv qab lub dav hlau hauv qab kom tsis txhob muaj dej tsub zuj zuj. Qhov thib ob, lub hopper tshwj xeeb yuav tsum tau muab tso rau ntawm qhov chaw sib txuas, thiab cov sealant yuav tsum tau ntim ntawm lub hopper thiab lub gutter, ruaj nws nrog tsawg kawg yog plaub stainless hlau screws. Thaum kawg, tag nrho cov gutter yuav tsum tuav txoj kab nqes ntev ntawm yam tsawg kawg 1% (txo li 1-2 cm txhua 10 meters), txoj kab nqes mus rau qhov ntws hopper; txwv tsis pub, txawm tias muaj tseeb haum, cov kua dej tsis zoo yuav ua rau cov txheej txheej laus thiab corrosion.
