Lub tswvyim ntawm "zinc phaj" - yog vim li cas nws thiaj li hu ua "zinc phaj" es tsis txhob "titanium zinc phaj"
Cov zinc (zinc) board feem ntau siv hauv kev tsim kho yog cov khoom siv hlau niaj hnub nrog cov khoom zoo heev tsim los ntawm kev ntxiv zinc ua cov khoom tseem ceeb thiab ntxiv me me ntawm titanium ({0}}.06% ~ 0.20% ), aluminium, thiab tooj liab alloy ntsiab. Nws tseem yog feem ntau hu ua "zinc" hauv Suav teb. Titanium zinc phaj".
Kev nkag siab ntawm "titanium-zinc phaj" tuaj yeem ua rau tsis meej pem nrog "titanium phaj" uas yog tsim los ntawm titanium hlau. Yog li ntawd, peb ntseeg hais tias "zinc phaj" yog yooj yim rau txhua leej txhua tus kom nkag siab thiab zoo dua qhia nws cov yam ntxwv feem.
Qhov zoo ntawm zinc phaj
Tom qab ntxiv tooj liab thiab titanium rau zinc, cov yam ntxwv ntawm zinc phaj ua zoo dua. Tooj liab zoo txhim kho lub zog tensile ntawm cov hlau. Titanium txhim kho kev nkag siab ntawm cov hlau phaj kom deformation dhau sijhawm. Lub alloy ntawm plaub hlau ua rau lub phaj Lub expansion coefficient yog txo. Cov txheej txheem European rau zinc nplooj ntawv rau kev tsim kho EN988 qhia tias ntxiv rau cov zinc tseem ceeb (Zn), cov tshuaj muaj pes tsawg leeg ntawm zinc-titanium alloy nplooj ntawv suav nrog titanium (Ti) cov ntsiab lus ntawm 0.06% ~0.20% thiab txhuas (Al) cov ntsiab lus tsis tshaj 0.015%. Cov ntsiab lus tooj liab (Cu) yog 0.08 ~ 1.{11}}%. Feem ntau zinc panels siv hauv kev tsim kho thoob ntiaj teb yog tsim raws li tus qauv no.
Thaum cov zinc phaj tuaj rau hauv kev sib cuag nrog carbon dioxide thiab dej hauv huab cua, cov txheej txheem tshuaj hloov pauv muaj ob theem tseem ceeb, uas yog tsim cov zinc hydroxide txheej thiab zinc carbonate txheej. Cov txheej txheej oxide tuab no ua raws li cov yeeb yaj kiab tiv thaiv kom tsis txhob muaj zinc sab hauv los ntawm kev xeb ntxiv, ua kom lub neej ua haujlwm ntev ntawm cov ntawv hlau. Ib lub koom haum sim kev ywj pheej tau saib xyuas cov phiaj xwm zinc hauv Ruhr Industrial Zone hauv lub teb chaws Yelemees rau 14 xyoo. Cov txiaj ntsig tau pom tias qhov nruab nrab corrosion poob ntawm zinc phaj txheej txheej ntawm lub ru tsev tiaj tus nrog txoj kab nqes dej ntawm 3% yog li 4µm / xyoo. Muab xam raws li feem ntau siv 0.7 hli tuab ru tsev panels, cov xeb tuab ntawm cov vaj huam sib luag yuav tsuas ncav cuag ib nrab ntawm cov thawj panels hauv 90 xyoo. Nws lub neej voj voog tuaj yeem ncav cuag thiab tshaj qhov ua tau zoo ntawm lub cev tseem ceeb ntawm lub tsev thib ob hauv kuv lub teb chaws; Thaum siv los ua phab ntsa vaj huam sib luag (nruab ntws), zinc phaj txheej txheej siv tus nqi tsawg dua 1-2µm / xyoo, thiab 0.7 hli tuab zinc phaj muaj lub neej theoretical txog li 200 xyoo thaum nws yog kev tu-dawb kiag li, uas tuaj yeem ncav cuag lossis txawm tshaj li thawj-chav ua haujlwm durability lub neej ntawm cov tsev. Lub neej voj voog ntawm cov qauv, uas txhais tau hais tias siv zinc ntawv cladding yuav luag ua tiav cov nyhuv teeb-thiab-tsis nco qab.
Hauv kev tsim kho, zinc daim hlau muaj qhov zoo dua piv nrog cov feem ntau siv galvanized steel daim hlau thiab txhuas daim hlau. Zinc phaj muaj cov khoom tiv thaiv tus kheej thiab tsis tas yuav muaj lwm yam tshwj xeeb los tiv thaiv corrosion. Txawm hais tias qhov chaw puas lawm, nws cov khoom tiv thaiv tus kheej tuaj yeem rov tsim cov txheej txheem tiv thaiv kom tsis txhob muaj corrosion ntxiv. Cov nplooj ntawv galvanized thiab cov ntawv txhuas yuav khawb lossis tev tawm ntawm cov zinc txheej lossis oxide zaj duab xis rau ntawm qhov chaw vim yog pob thiab lwm yam laj thawj, thiab tom qab ntawd raug corroded, yog li yuav tsum tau them nqi kho ntxiv.
Tsis tas li ntawd, zinc alloy yog ib qho yooj yim rau kev tsim thiab vuam, tsis ua rau muaj kuab paug rau ib puag ncig ib puag ncig, thiab muaj cov khoom siv khib nyiab siab. Txawm hais tias tus nqi ntawm zinc panels yog tus nqi siab, xav txog nws lub neej ntev dua, kev siv lub neej txij nkawm-dawb zinc panels yog ib qho kev xaiv zoo tshaj plaws thiab kev lag luam.
Raws li cov khoom sib txawv ntawm cov hlau thiab cov txheej txheem electrochemical, zinc phaj tuaj yeem sib cuag nrog cov hlau lead, txhuas, stainless hlau, coated steel daim hlau, tsis txhob sib cuag nrog tooj liab, tsis muaj coated steel phaj, thiab tib lub sijhawm, los ntawm siab mus rau qis ( los ntawm sab nraud mus rau sab hauv)) Cov hlau sib xyaw ua ke yuav tsum yog txhuas, zinc, coated steel phaj, txhuas, tooj liab.
Ib txwm tsis kho thawj xim zinc panels yog ci dawb dawb thiab tsis tshua siv nyob rau hauv cov vaj tsev zoo li lawv yuav maj mam oxidize thiab hloov xim hauv qhov chaw. Tau kawg, lub tsev tsis hloov pauv tsis tas yuav muaj txiaj ntsig uas txhua tus kws tsim vaj tsev nrhiav. Cov txheej txheem oxidation thiab discoloration no tuaj yeem ntxiv lub tswv yim ntawm lub sijhawm rau lub tsev, thiab tuaj yeem qhia cov ntsiab lus tshwj xeeb thaum siv hauv qee lub tsev tshwj xeeb.
Feem ntau siv zinc panels hauv tsev yog Hoobkas-preoxidized silver-grey. Cov xim no txawv ntawm oxidation txheej ib txwm tsim ntawm zinc panels hauv cov cua. Nws tuaj yeem nyob ntev mus txog rau thaum cov txheej txheem ua ntej oxidation puas lawm, uas yog ib qho tseem ceeb heev rau zinc panels. Nws yog qhov zoo los tswj cov duab ntev ntawm lub tsev thiab tsis txhob muaj xim sib txawv thaum kho thiab hloov cov panels. Ntxiv nrog rau prefabricated silver-grey zinc panels, qee lub tuam txhab kuj muab prefabricated dub-grey zinc panels thiab lwm yam xim zinc panels nrog tshwj xeeb kev kho xim txheej.
