Dab tsi yog pre-galvanized steel yeeb nkab?
Raws li peb txhua tus paub, cov kav hlau kub-dipped galvanizedyog ib hom yeeb nkab hlau uas tau tsim thiab galvanized afetrwards.Yog li nws kuj hu ua post-galvanized steel tubes.
Vim li cas cov yeeb nkab hlau galvanized lossis cov yeeb nkab hlau galvanized yog hom kev tsim cov yeeb nkab hlau galvanized nrov tshaj plaws? Qhov laj thawj yog cov khoom siv uas xav tau rau kev tsim khoom pheej yig thiab cov txheej txheem no yooj yim heev. Tsis zoo li cov yeeb nkab hlau galvanized kub-dip, cov ntawv hlau galvanized xav tau lub sijhawm ua tiav luv dua, ua rau cov txheej hlau-zinc alloy nyias dua thiab cov txheej zinc ntshiab tuab dua.
Txawm li cas los xij, vim tias cov cua sov tsim tawm thaum lub sijhawm welding ntawmcov kav hlau ua ntej galvanizedYog tias cov zinc txheej tshem tawm ntawm cov hlau, cov hlau uas raug nthuav tawm yuav tsum tau rov kaw dua siv cov txheej txheem zinc thermal spraying. Qhov no kuj txhais tau tias cov vuam ntawm phab ntsa sab hauv ntawm cov yeeb nkab yuav tsis raug galvanized. Cov yam ntxwv sacrificial anode ntawm zinc ua kom ntseeg tau tias cov vuam sab hauv uas raug nthuav tawm tsis ua rau cov khoom tsis kam rau corrosion lossis lub neej ua haujlwm.
Kev ua ntej galvanizing suav nrog kev muab cov ntawv hlau tso rau hauv cov zinc molten rau txheej. Tom qab ntawd, cov ntawv raug txiav kom loj thiab rov qhwv. Thaum lub sijhawm ua ntej galvanizing, ib qho tuab ntawm zinc txheej raug siv rau tag nrho cov ntawv. Piv txwv li, cov hlau Z275 ua ntej galvanized muaj zinc txheej ntawm 275 grams ib square meter.
Piv rau cov hlau galvanized kub-dip, cov hlau galvanized ua ntej muaj qhov zoo dua hauv nws qhov tsos zoo dua. Tsis tas li ntawd, nws feem ntau pheej yig dua. Cov ntaub ntawv ua ntej galvanized siv dav hauv ntau yam khoom, suav nrog cov kav dej, flanges, thiab cov channel uas nthuav tawm.
Qhov txawv ntawm ua ntej yog dab tsi?-hlau galvanizedcov kav dejthiab cov hlau galvanizedcov kav dej?
Kev galvanization kub-dipped suav nrog kev muab tag nrho cov hlau lossis cov qauv hlau rau hauv lub thawv zinc uas yaj, ua rau muaj txheej txheej tas mus li ntawm qhov chaw. Kev ua ntej-galvanizing yog ua tiav ntawm theem thawj zaug, ua ntej cov ntawv raug txiav ua qhov loj me thiab daim, yog li cov npoo txiav tsis tau coated.
Tianjin Yuantai Derun Grouptsim cov kav hlau uas tau galvanized ua ntej raws li cov qauv thoob ntiaj teb xws li ASTM, JIS, BS, DIN, EN, thiab GB. Cov hom seem muaj xws li puag ncig, plaub fab, plaub fab plaub fab, oval, thiab lwm yam duab tshwj xeeb kom tau raws li ntau yam kev xav tau ntawm cov qauv thiab kev lag luam.
Cov raj xa dej ua los ntawm cov hlau galvanized uas tau ua ntej lawm yog cov qauv kev lag luam rau cov laj kab, thiab cov neeg ua haujlwm, cov kws kes duab vajtse thiab cov engineers siv. Cov kws kes duab vajtse thiab cov kws kes duab vajtse tau siv cov laj kab hlau los tsim ntau yam chaw nkaum, cov qauv teeb pom kev zoo thiab cov duab puab zoo nkauj rau txoj kev, cov tiaj ua si, chaw nres tsheb npav thiab tsheb ciav hlau, cov khw muag khoom loj, cov chaw ua si kis las, cov tsev ua haujlwm, cov chaw nres tsheb thiab lwm yam chaw. Cov laj kab hlau tau tsim ua tib zoo nrog cov kab huv si, kev ua kom zoo thiab yooj yim rau kev teeb tsa. Cov laj kab no muaj ntau yam qhov siab thiab dav hauv ntau qhov kev teeb tsa.
Dab tsi'yog lubDaim ntawv thov yeeb nkab ua ntej galvanizeds?
Cov kav hlau galvanized ua ntej siv rau ntau qhov chaw, xws li cov qauv hlau, cov qauv tsim kho, cov laj kab thaiv, cov rooj tog hlau thiab lwm yam. Peb cov khoom raug xa tawm mus rau kwv yees li 45 lub tebchaws thoob ntiaj teb, thiab peb tau txais kev lees paub ntau los ntawm peb cov neeg siv khoom rau qhov zoo thiab kev pabcuam peb muab.
