1.What yog cov tseem ceeb yog qhov zoo ntawm txias - rollugized galugated ntawv?
Txias -} rolled galvanized corrugated sheet: lub substrate yog them nrog ib txheej sib dhos ntawm zinc (kub}} dip galvanizing). Cov ZINC ua rau rov qab los nrog oxygen thiab noo noo nyob rau hauv huab cua, sib sau ib tug tuab tiv thaiv cov yeeb yaj kiab ntawm zinc oxide, zinc hydroxide, thiab zinc carbonate. Cov yeeb yaj kiab zaj duab xis no khov kho rau cov ntawv saum npoo av, tiv thaiv corrosion ntawm txias- rolled steel substrate. Txawm hais tias lub zinc txheej yog ib nrab puas, puag ncig Zinc Txheej tseem tiv thaiv cov hlau ua kom zoo li ntawm "kev ua kom qeeb qeeb ntawm cov xeb.
Tsim nyog rau sab nraum zoov ib puag ncig (xws li cov rooj puag ncig thiab thawv cladding) thiab huab cua chaw ua haujlwm txias (xws li cov khoom lag luam cia txias), nrog lub neej pabcuam tshaj 30 xyoo.
Daim ntawv qhia txog corrugated zoo tib yam (xws li txias {{k} Tsis muaj kev tiv thaiv cov ntawv thiab kub.}} Thaum raug rau ya raws, ntsev (xws li nyob rau hauv ntug hiav txwv), lossis cov kuab paug, tsim cov hlau xoob, xeb xoob (xeb xoob (xeb). Qhov xeb xeb no tsis tu ncua, txo cov ntawv tuab thiab lub zog. Muaj feem xyuam nrog cov xwm txheej: Nws tsuas siv tau rau hauv qhuav, tsis - corrosive nyob rau hauv lub tsev nyob sab hauv ntawm cov tais sab hauv ib ntus). Cov kev pabcuam lub neej feem ntau tsuas yog 5-10 xyoo, thiab ntau kev rov pleev xim thiab txij nkawm yuav tsum muaj.
2.Qhov dab tsi yog qhov kev ua tau zoo ntawm txias - rolled galuganized corrugated daim ntawv?
Nce zog thiab deformation tsis kam
Txias -} rolled galvanized corrugated daim ntawv yog tsim los ntawm khaub thuas- rolled steel puag. Lub txias - Rolling cov txheej txheem ua rau muaj cov qauv zoo nkauj thiab ntau dua cov qauv kev sib tw, feem ntau ≥235 mpa) thiab hardness. Ua ke nrog cov ntawv corrugated tus qauv siv hluav taws xob, cov ntawv muab kev txhim kho kom tsis kam rau kev cuam tshuam, cua thauj khoom, thiab daus siab. Nws kuj tseem tsis tshua mob ua rau muaj kev ua rog thiab deformation vim yog cov tub sab sab nraud lossis kub nrawm dua (thermal expansion thiab mertaction) dhau lawm- siv.
Cov ntawv txheeb ze zoo tib yam siv kub - Rolled puag thiab cov tsis zoo ua rau cov kev ntxhov siab yas. Siv daim nyias nyias {{2} kev thov, txias}} Ntau hloov pauv tau vuam thiab ua lub peev xwm. Lub zinc txheej ntawm txias {{rolled galvanized corrugated daim ntawv ("metallurgical bonding" tus yam ntxwv ntawm kub {}} dip galvanizing txheej txheem). Qhov no tiv thaiv cov txheej zinc txheej los ntawm cov ntaub pua chaw thaum lub sijhawm vuam (piv txwv li, ntawm - Site Ruv Splicing). Tsis tas li ntawd, qhov txias - Rolled lub hauv paus ntawv muaj kev sib txuas zoo heev ntawm chaw thiab leeg vuam. Nws tseem txhawb rau ntawm -} mus rau cov ntaub thaiv npog nrog ntsia hlau, thiab pom kev ua ntej rau cov yeeb nkab ntau dua (piv txwv li.
Cov ntawv txheeb ze zoo tib yam nrog kub - Rolled Base Sheet yog nquag mus rau ntau dhau lawm splating heev thaum vuam thiab xeb ncig ntawm weld seams. Rau cov ntawv nrog cov txheej yooj yim (piv txwv li, txau -} PoT, Vuam tuaj yeem ua kev puas tsuaj, uas yuav tsum tau ua ntxiv ntawm lub installation.
3.Qhov yog cov nyiaj txiag zoo ntawm txias - rollugal galugaled ntawv?
Txawm hais tias thawj zaug yuav tus nqi txias - rollugal corrugated daim ntawv, nws yog ntau tshaj kev lag luam los ntawm kev pom ntawm "lub neej lub neej".
4.Yog dab tsi yog cov txiaj ntsig zoo ntawm txias- rolled galuganized corrugated ntawv?
Lub zinc txheej ntawm cold -}} maluganized corrugated daim ntawv ib "crystallized cov qauv ntawm nws cov npoo, tsim cov qauv ua kom zoo nkauj. Cov txheej xim ntxiv (xws li PVDF fluorocarbon txheej lossis PE Polyester txheej) tso cai rau cov xim kev cai (piv txwv, liab, xiav, lossis grey). Cov txheej muab cov ntawv sib txuas ua ke nrog zinc txheej, thiab ua kom muaj zog siv UV thiab ploj mus, tswj nws lub ntsej muag muaj zog txawm tias nyob hauv qab ntev} Lub hnub ci tshav ntuj raug. Qhov no ua rau nws haum rau cov kws kos duab kos ntawv thov kom zoo nkauj, xws li cov tsev ua liaj ua teb niaj hnub thiab kev txhawb nqa cov vaj tse.
Uncoated, zoo tib yam corrugated khaws cov xim qub ntawm cov hlau substrate, uas yog nquag mus rau xeb thiab tsaus ntuj nti, ua rau muaj kev pom zoo. Txawm hais tias muaj tshuaj tsuag dej ntshiab yooj yim, cov xim yooj yim peels thiab fades vim muaj xeb ntawm substrate, deterating nws lub ntsej muag nyob rau lub sijhawm.
5.How ua cov tub ntxhais sib txawv ntawm ob qho sib piv?
Corrosion Kuj: Txias -}} rolled galuganized corrugated yog muaj zog (Zinc txheej tiv, xeb +); Daim ntawv dog dig corrugated tsis muaj zog (tsis muaj kev tiv thaiv, yooj yim rau xeb, txhuam hauv 5-10 xyoo)
Kev Pab Lub Neej: Ntau tshaj 30 xyoo rau cold- rollugized galugated ntawv; 5-10 xyoo rau cov ntawv zoo tib yam
Lub zog thiab deformation kuj: cold {{0} {dov lub zog muaj lub zog siab (khaub noom txias}}} Daim ntawv dog dig corrugated muaj tsawg lub zog (yooj yim rau deform, lub zog poob tom qab xeb)
