Galvanized ntawv thiab stainless hlau ntawv
Cov ntawv galvanized yog kom tsis txhob xeb ntawm qhov chaw ntawm cov phaj tuab tuab thiab ua kom nws lub neej ua haujlwm.
Qhov saum npoo ntawm cov phaj tuab yog coated nrog ib txheej ntawm hlau zinc.
Qhov no hom ntawm galvanized txias dov steel ntawv yog hu ua galvanized ntawv.
Kub-dov galvanized sawb cov khoom lag luam feem ntau yog siv hauv kev tsim khoom lag luam, xws li kev tsim vaj tsev, kev lag luam teeb, trolleys, kev ua liaj ua teb, tsiaj txhu thiab nuv ntses, thiab kev lag luam.
Ntawm lawv, kev tsim kho kev lag luam tsim nyog rau kev tsim cov khoom lag luam corrosion-resistant thiab cov xim hlau ru tsev thiab ru tsev grills ntawm cov tsev lag luam;
kev lag luam metallurgical siv nws los tsim cov khoom siv hauv tsev, cov kav dej hauv tsev, cov khoom siv hauv tsev, thiab lwm yam.,
thiab kev lag luam tsheb tsim khoom tsim nyog rau kev tsim tsheb.
Anti-corrosion Cheebtsam.
Kev ua liaj ua teb, tsiaj txhu thiab nuv ntses feem ntau yog siv rau kev khaws khoom noj thiab kev thauj mus los,nqaij cov zaub mov thiab nqaij nruab deg tub yees ntau lawm thiab cov khoom siv, thiab lwm yam.cov kev pabcuam kev lag luam feem ntau yog siv rau cov khoom siv, kev cia khoom thiab ntim khoom.
Stainless hlau galvanized ntawv hais txog cov hlau uas tiv taus cov khoom tsis muaj zog corrosive xws li roj, chav,dej thiab cov organic tshuaj corrosive xws li acids, alkalis thiab ntsev.
Kuj tseem hu ua stainless hlau thiab acid-resistant steel.
Hauv qee qhov kev siv, steel resistant rau tsis muaj zog corrosive tshuaj feem ntau hu ua stainless hlau,hos steel resistant rau hnyav tshuaj hu ua acid-resistant steel.
Raws li nws cov txheej txheem, stainless hlau daim hlau feem ntau faib ua austenitic steel, ferritic steel,ferritic steel, ferritic metallographic qauv (duplex) stainless hlau phaj thiab kev sib haum xeeb nyuaj stainless hlau phaj.
Tsis tas li ntawd, nws tuaj yeem faib ua chromium stainless hlau phaj, chromium-nickel stainless hlau phaj thiab chromium manganese nitrogen stainless hlau phaj.
Yog vim li cas
Qhov kev tiv thaiv corrosion ntawm galvanized stainless hlau ntawv txo qis nrog qhov nce ntawm cov ntsiab lus carbon.
Yog li ntawd, cov ntsiab lus carbon ntawm feem ntau stainless hlau daim hlau yog tsawg, tsis pub tshaj 1.2%,thiab Wc (cov ntsiab lus carbon) ntawm qee cov hlau tseem tsawg dua 0.03% (piv txwv li, 00Cr12).
Lub ntsiab tseem ceeb ntawm aluminium alloy nyob rau hauv stainless hlau phaj yog Cr (chromium).
Tsuas yog thaum cov dej ntsiab lus ntawm Cr ntau tshaj ib qho nqi, cov hlau muaj corrosion kuj.
Yog li ntawd, cov dej dav dav Cr (chromium) cov ntsiab lus ntawm stainless hlau phaj yog tsawg kawg yog 10.5%.
Stainless hlau phaj tseem muaj cov khoom xws li Ni, Ti, Mn, N, Nb, Mo thiab Si.
Galvanized stainless hlau ntawv tsis yooj yim ua rau corrosion, crevice corrosion, xeb, lossis puas.
Ntawm cov khoom siv hlau sib xyaw rau kev siv engineering, stainless hlau daim hlau kuj yog ib qho ntawm cov khoom siv raw nrog lub zog siab tshaj plaws.
Raws li stainless hlau phaj muaj zoo heev corrosion kuj.
Nws tuaj yeem ua rau cov tswv cuab hauv cov qauv tsim kom muaj kev sib luag ntawm cov qauv tsim vaj tsev tsim vaj tsev.
Cov chromium-muaj stainless hlau phaj kuj muaj kev cuam tshuam toughness thiab siab ductility,uas yog qhov yooj yim rau kev tsim, ua thiab tsim cov khoom, thiab cov kev xav tau ntawm architects thiab tag nrho cov tsim qauv tuaj yeem txiav txim siab.
