Galvanized hlau muaj zoo heev toughness thiab elasticity, nrog ib tug zinc txheej hnyav uas muaj peev xwm ncav cuag 300 grams ib square meter. Vim nws tuab zinc txheej, nws muaj zog corrosion kuj. Galvanized hlau yog dav siv nyob rau hauv kev tsim kho, handicrafts, hlau mesh weaving, txoj kev loj guardrails, cov khoom ntim, thiab ntau yam kev siv pej xeem. Nws yog feem ntau categorized rau kub-dip galvanized hlau thiab txias-galvanized (electro-galvanized) hlau.
Kub-dip galvanized hlau yog tsim los ntawm dipping cov hlau rau hauv da dej ntawm zinc molten; txheej txheem yog ceev, ua rau ib tug tuab tab sis tsis sib xws txheej. Txheej thickness yog li ntawm qhov tsawg kawg nkaus ntawm 45 microns mus rau ntau tshaj 300 microns. Kub-dip galvanized hlau muaj qhov tsos tsaus dua thiab siv zinc ntau dua; nws tsim ib txheej txheej txheej alloyed nrog lub hauv paus hlau, uas ua rau zoo corrosion kuj. Nws tuaj yeem nyob ruaj khov rau ntau xyoo hauv qhov chaw sab nraum zoov.
Txias-galvanized (electro-}galvanized) hlau yog tsim los ntawm kev siv lub tshuab hluav taws xob unidirectional nyob rau hauv lub da dej electroplating kom maj mam tso zinc rau ntawm cov hlau; Cov txheej txheem qeeb qeeb, ua rau cov txheej txheej tsis sib xws feem ntau tsuas yog 3-15 microns tuab. Thaum nws muaj qhov ci ci, ci ntsa iab, nws qhov kev tiv thaiv corrosion tsis zoo, thiab nws feem ntau pib xeb hauv ob peb lub hlis. Electro-galvanized hlau muaj nqi ntau lawm piv rau kub-dip galvanized hlau.
Vim tias nws cov txheej tuab thiab kev tiv thaiv zoo tshaj plaws, kub -dip galvanized hlau yog tsim rau kev ua haujlwm hnyav. Nws yog dav siv nyob rau hauv kev lag luam xws li tshuaj ua, roj av refining, marine kev tshawb fawb, hlau structural engineering, fais fab kis, thiab shipbuilding. Nws kuj pom muaj ntau daim ntawv thov hauv kev ua liaj ua teb (xws li, cov kav dej, kev tsim tsev cog khoom) thiab kev tsim kho kev lag luam (xws li, dej thiab roj kav dej, cov kav dej hluav taws xob, scaffolding, txuas hniav, thiab kev loj guardrails).
Stainless hlau hlau khoom
Stainless hlau hlau yog tsim los ntawm cov hlau uas tiv thaiv corrosion los ntawm cov xov xwm me me (xws li huab cua, chav, thiab dej) nrog rau cov tshuaj lom neeg tawm tsam (xws li acids, alkalis, thiab ntsev); nws tseem hu ua stainless acid-resistant steel. Hauv kev siv tswv yim, steel resistant rau me me corrosive xov xwm feem ntau hu ua "stainless steel," thaum steel resistant rau tshuaj lom neeg yog hu ua "acid-resistant steel." Vim qhov sib txawv ntawm cov tshuaj muaj pes tsawg leeg, stainless hlau tsis tas yuav tiv taus corrosion los ntawm cov tshuaj lom neeg, hos acid-resistant steel feem ntau muaj cov khoom tsis zoo.
Lub corrosion kuj ntawm stainless hlau nyob ntawm nws alloying ntsiab. Hlau kos duab yog cov txheej txheem kev kho saum npoo nrov siv rau cov khoom siv hlau stainless thiab txhuas los tsim cov nyhuv zoo nkauj tshwj xeeb.
Cov hlau tsis muaj hlau tsis sib xws- kos duab tiav suav nrog ncaj- kab qauv, cov qauv snowflake, thiab cov qauv nylon. Ncaj- kab qauv muaj cov kab nruam khiav ntawm sab saum toj mus rau hauv qab; cov qauv snowflake yog tsim los ntawm cov dot formations; thiab cov qauv nylon muaj cov kab sib txawv ntawm qhov ntev. Cov hlau- txheej txheem kos duab xav tau qhov tseeb; Cov tshuab tshwj xeeb feem ntau yog siv los kho thiab sib tov khawb thiab vuam seams, ua kom muaj kev sib koom ua ke, kos duab ua tiav thoob plaws tag nrho saum npoo.
