1. Dab tsi yog galvanized xim -coated steel kauj? Nws "weather resistance" tshwj xeeb yog hais txog dab tsi?
A: Galvanized xim-coated steel kauj yog cov khoom sib xyaw ua los ntawm txheej ib lossis ntau txheej ntawm cov xim organic rau saum npoo ntawm cov ntawv hlau galvanized, tom qab ntawd ci thiab kho.
Nws "huab cua tsis kam" yog hais txog txheej txheej muaj peev xwm tiv taus ib puag ncig kev yaig thiab tswj nws cov tsos thiab ua haujlwm. Qhov no suav nrog kev tiv thaiv fading, chalking, cracking, thiab blistering tshwm sim los ntawm tshav ntuj, nag, kub, thiab atmospheric pa phem. Koj tuaj yeem xav tias nws yog "cov cuab yeej sib xyaw" uas muab kev tiv thaiv ruaj khov rau cov hlau substrate.
2. Dab tsi yog qhov tseem ceeb txiav txim siab huab cua tiv thaiv lub neej ntawm cov xim galvanized-coated coils?
A: Huab cua tiv thaiv lub neej yog txiav txim siab los ntawm peb yam tseem ceeb:
Txheej txheej (qhov ncaj tshaj "sov"): Qhov no yog qhov sib txawv tseem ceeb tshaj plaws. Cov txheej txheej sib txawv muaj qhov sib txawv tseem ceeb hauv huab cua tsis kam:
Polyester txheej (PE): Tus nqi qis dua, tab sis feem ntau qis dua huab cua tsis kam, lub neej ntev li ntawm 5-10 xyoo.
Silicone-hloov polyester txheej (SMP): Cov huab cua zoo dua li PE, lub neej ntev li ntawm 10-15 xyoo.
High- huab cua- tiv taus polyester txheej (HDP): Kev ua tau zoo ntxiv, kev ua neej nyob tuaj yeem ncav cuag 15 xyoo.
Fluorocarbon txheej (PVDF): Kev ua tau zoo tshaj plaws, muaj zog tiv thaiv UV rays thiab tshuaj lom neeg, kev ua neej nyob feem ntau tshaj 20 xyoo, qhov kev xaiv zoo tshaj plaws rau siab -kawg vaj tse thiab ntug hiav txwv dej.
Substrate thiab Txheej (Lub Load-Baring "Inner Layer"):
Substrate Hom: Aluminium-zinc (GL) substrates muab 2-5 npaug ntawm corrosion kuj ntawm zinc-plated (GI) substrates, muab kev tiv thaiv lub substrate ntev dua.
Txheej Thickness: Cov txheej txheej hnyav dua (xws li Z180, AZ150) ua rau muaj zog corrosion kuj thiab lub sijhawm tiv thaiv ntev dua.
Kev Siv Ib puag ncig (External "Tests"):
Kev faib tawm ib puag ncig: Lub neej tiag tiag ntawm cov ntaub ntawv tuaj yeem sib txawv los ntawm ntau zaus, los ntawm cov chaw nyob deb nroog qhuav (C1) mus rau siab - av noo, siab - thaj chaw ntsev ntug dej hiav txwv (C5).
Ib puag ncig tshwj xeeb: Cov tshuaj tsuag ntsev hauv cov ntug dej hiav txwv thiab cov kua qaub / alkaline gases hauv thaj chaw muaj kev ua kom muaj zog corrosion.
3. Raws li kev siv ib txwm muaj, qhov kwv yees huab cua tiv thaiv lub neej ntawm qib sib txawv ntawm cov xim galvanized yog dab tsi-coated coils?
A: Cov lus hauv qab no qhia txog lub neej kev pab cuam ntawm kev teeb tsa sib txawv raws li ib puag ncig:
Txheej hom|Ib puag ncig daim ntawv thov|Cia siab rau Kev Pabcuam Lub Neej
Polyester Txheej (PE)|Inland qhuav chaw, dav factories, warehouses|7 - 15 xyoo
Silicone Hloov Polyester (SMP) / Huab cua siab -Resistant Polyester (HDP)|Lub nroog sab nrauv, thaj chaw muaj teeb pom kev zoo, cov tsev lag luam dav dav|15 - 20 xyoo
Fluorocarbon Txheej (PVDF)|Cov cheeb tsam ntug hiav txwv, siab UV hluav taws xob, hnyav ntau qhov chaw ua lag luam|20 - 30 xyoo
4. Yuav ua li cas los txiav txim seb lub chaw tsim khoom "20-xyoo warranty" puas ntseeg tau?
A: Thaum ntsib nrog kev cog lus txuas ntxiv los ntawm cov chaw tsim khoom, koj tuaj yeem ua qhov kev txiav txim siab zoo raws li peb lub ntsiab lus hauv qab no:
Thov kom tsis txhob muaj: Kom meej meej thov cov ncauj lus kom ntxaws xws li xim zaj duab xis thickness (primer + topcoat) thiab txheej khoom / hnyav, thiab ceev faj ntawm vague thov.
Tshawb xyuas hom substrate: Paub meej tias qhov kev cog lus lav yog raws li qhov siab -kev ua haujlwm substrates xws li aluminium-zinc (AZ) lossis zinc- aluminium-magnesium (AM), vim qhov no yog lub hauv paus rau ntev -lub sij hawm corrosion.
Thov cov ntaub ntawv ntsuam xyuas: Thov kom pom cov ntaub ntawv tshaj tawm los ntawm cov chaw soj nstuam tso cai ntawm kev kuaj tshuaj ntsev nruab nrab thiab UV aging tests txhawm rau txheeb xyuas cov lus cog tseg nrog cov ntaub ntawv.
5. Yuav ua li cas kom ntev lub neej kev pab cuam ntawm galvanized xim -coated coils thaum lub sij hawm yuav khoom thiab kev tsim kho?
A: Ntxiv nrog rau kev xaiv cov ntaub ntawv raug, cov khoom tom ntej "30% khoom, 70% kev ua haujlwm" yog qhov tseem ceeb:
Scientific Design: Txhim kho lub ru tsev txoj kab nqes kom tsis txhob ntev -lub sij hawm dej thiab plua plav.
Fine Processing: Tiv thaiv cov txheej thaum ua kom tsis txhob khawb. Ntug ntawm - nplooj ntawv txiav ntawm qhov chaw yuav tsum tau coated nrog cov tshuaj tiv thaiv - xeb xim los yog sealant los tiv thaiv kev sib kis ntawm corrosion.
Standardized Installation: Xyuas kom cov fasteners raug kaw kom zoo los tiv thaiv dej seepage.
Kev Kho Kom Zoo: Tsis tu ncua ntxuav qhov chaw, tshuaj xyuas thiab kho cov kev puas tsuaj hauv zos; qhov no tuaj yeem ncua sijhawm cov khoom laus.
