Galvanized square yeeb nkabyog ib tug hollow square cross-section steel yeeb nkab nrog ib tug square cross-section duab thiab loj ua los ntawm kub dov los yog txias dov galvanized sawb hlau los yog galvanized coil phaj, uas yog tsim los ntawm txias dabtsi yog khoov thiab ces high-frequency welding, los yog galvanized. square square kav dej ua los ntawm kub-dip galvanizing lub pre-ua txias-tsim hollow steel kav.
【Classification】
Galvanized square raj tau muab faib uaKub-dip galvanized square tubesthiab txias-dip galvanized square raj nyob rau hauv cov nqe lus ntawm ntau lawm technology. Nws yog precisely vim hais tias ntawm qhov sib txawv ntawm cov ob galvanized square raj uas lawv muaj ntau yam sib txawv lub cev thiab tshuaj. Feem ntau hais lus, lawv muaj ntau qhov sib txawv ntawm lub zog, toughness thiab mechanical zog.
Kub-dip galvanized square tube: Nws yog ib lub raj square ua los ntawm vuam steel phaj los yog steel sawb tom qab tau curled thiab tsim. Nyob rau hauv lub hauv paus ntawm lub square tube, lub square raj yog muab tso rau hauv ib tug kub-dip galvanizing pas dej ua ke thiab undergoes ib tug series ntawm tshuaj tshua. Ib lub raj square tsim. Cov txheej txheem ntau lawm ntawm kub-dip galvanized square tubes yog qhov yooj yim, cov khoom siv tau zoo heev, thiab muaj ntau ntau yam thiab specifications. Hom square tubes no yuav tsum tau siv cov khoom me me thiab nyiaj txiag, thiab tsim nyog rau kev tsim cov khoom me me galvanized square tube manufacturers. Txawm li cas los xij, nyob rau hauv cov nqe lus ntawm lub zog, lub zog ntawm cov yeeb nkab steel no yog qis dua li ntawm seamless square kav.
Cold-dip galvanized square tube: Cold-dip galvanized square tube siv lub hauv paus ntsiab lus ntawm txias galvanizing los ua cov square raj los tiv thaiv corrosion. Sib txawv ntawm kub-dip galvanizing, txias-dip galvanizing txheej tsuas yog siv cov txheej txheem electrochemical los tiv thaiv corrosion. Yog li ntawd, nws yog ib qho tsim nyog los xyuas kom meej tag nrho kev sib cuag ntawm zinc hmoov thiab hlau los tsim ib qho electrode muaj peev xwm sib txawv, yog li kev kho saum npoo ntawm cov hlau tseem ceeb heev.
[Qhov txawv ntawm kub thiab txias galvanizing]
Galvanized square raj tau muab faib ua ob pawg: kub-dip galvanized square raj thiab electro-galvanized square raj. Kub-dip galvanized square kav muaj xws li txoj kev ntub dej, txoj kev qhuav, txoj kev txhuas-zinc, txoj kev redox, thiab lwm yam. tom qab acid leaching tu ntawm cov yeeb nkab steel. Txoj kev qhuav thiab redox txoj kev yog siv rau hauv kev tsim khoom tam sim no, thiab lawv cov yam ntxwv tau qhia hauv lub rooj. Qhov saum npoo ntawm zinc txheej ntawm electro-galvanizing yog heev du, ntom thiab sib xws hauv cov qauv; nws muaj zoo mechanical zog thiab corrosion kuj; zinc noj yog 60% mus rau 75% qis dua qhov kub-dip galvanizing. Electro-galvanizing yog technically complex, tab sis txoj kev no yuav tsum tau siv rau ib leeg-tog coatings, ob-sided coatings nrog txawv txheej thicknesses nyob rau hauv sab hauv thiab sab nrauv, thiab nyias-walled yeeb nkab galvanizing.
【siv】
Txij li thaum galvanized square tubes yog galvanized ntawm square tubes, daim ntawv thov ntau yam ntawm galvanized square tubes tau nthuav dav heev piv rau cov raj square. Nws yog tsuas yog siv nyob rau hauv cov ntaub thaiv phab ntsa, kev tsim kho, machinery manufacturing, steel siv tej yaam num, shipbuilding, hnub ci zog tiam brackets, steel qauv engineering, hluav taws xob engineering, fais fab nroj tsuag, kev ua liaj ua teb thiab tshuaj machinery, iav kab hlau rhuav phab ntsa, tsheb chassis, tshav dav hlau, thiab lwm yam.
【 yam ntxwv】
Galvanizing muaj zog tiv thaiv cov nyhuv thiab muaj zog corrosion kuj. Tag nrho cov qauv yog ua los ntawm zinc, tsim ib tug ntom quaternary siv lead ua. Cov siv lead ua no ua ib qho kev thaiv ntawm cov hlau phaj, yog li tiv thaiv corrosion yam tsis zoo los ntawm kev nkag mus. Corrosion kuj los ntawm cov txheej txheem tiv thaiv muaj zog ntawm zinc. Thaum zinc muab kev tiv thaiv kev txi ntawm cov npoo npoo, khawb, thiab khawb qhov chaw ntawm cov txheej, zinc tsim cov txheej txheem oxide insoluble thiab ua lub luag haujlwm tiv thaiv kev tiv thaiv.
