Lub npe "galvanizing" yog thawj zaug siv rau cov txheej txheem tsim los ntawm Stanislas Sorel. Nyob rau hauv 1836 nws patented ib tug txheej txheem ntawm tu steel thiab ces coating nws nrog zinc los ntawm dipping rau hauv molten zinc.
Thaum twg Galvanized tsim?
In 1836, Sorel hauv Fab Kis tau tawm thawj zaug ntawm ntau patents rau txheej txheem txheej hlau los ntawm dipping hauv zinc molten tom qab thawj zaug ntxuav nws. Nws muab cov txheej txheem nrog nws lub npe 'galvanizing'.
galvanized steel tau txais nws lub npe li cas?
Steel dipped nyob rau hauv molten zinc ua fashionable rau ua lauj kaub, lauj kaub, thiab kettles uas yuav tsis corrode ntau xyoo ntawm kev siv. Cov khoom no tau los ua lub npe hu ua "galvanized" tsis yog vim kev tsim khoom, tab sis vim yog cov ntsiab lus tshuaj uas nws tau hais tseg.
galvanized hlau yog dab tsi?
Kub-dip galvanizing yog txheej txheem ntawm immersing hlau lossis hlau hauv da dej ntawm zinc molten los tsim cov tshuaj tiv thaiv corrosion, ntau txheej txheej ntawm zinc-hlau alloy thiab zinc hlau. Thaum cov hlau nkag rau hauv zinc, cov tshuaj tiv thaiv metallurgical tshwm sim ntawm cov hlau hauv cov hlau thiab cov zinc molten.
Dab tsi yog qhov tshwj xeeb ntawm galvanized steel?
Muaj ntau ntau cov txheej txheem galvanizing muaj, tab sis feem ntau muab thiab siv txoj kev hu ua kub-dip galvanizing. Galvanized steel yog ib qho ntawm cov hlau nrov tshaj plaws vim ntawm nws cov kav ntev,muaj lub zog thiab formability ntawm hlau ntxiv rau kev tiv thaiv corrosion ntawm zinc-hlau txheej.

Vim li cas hlau tsis tsim nyog raws li cov tub ntxhais ntawm cov hlau nplaum?
Yog cov hlau siv los ua cov tub ntxhais ntawm cov hlau nplaum, cov hlau tsis plam tag nrho nws cov hlau nplaum thaum tam sim no nres thiab nws dhau los ua cov hlau nplaum ruaj khov. Yog li cov hlau tsis siv los ua lub hauv paus ntawm electromagnet.
Puas yog cov ntsia hlau tiav galvanized?
Tiav rau tes muab cov tshuaj seamless rau fastening koj cov hniav moldings thiab sab nrauv trim. Cov ntsia hlau no muaj qhov kub-dipped galvanized tiavuas muaj kev tiv thaiv corrosion zoo tshaj plaws rau sab nraum zoov. Koj puas tuaj yeem siv cov ntsia hlau ua tiav sab nraud?
Leej twg tsim cov hlau ore smelting?
Txoj kev loj hlob ntawm cov hlau smelting yog ib txwm ua los ntawm cov neeg Hittites ntawm Anatoliantawm lub hnub nyoog Bronze lig. Nws tau ntseeg tias lawv tswj hwm txoj haujlwm ntawm cov hlau ua haujlwm, thiab lawv lub tebchaws tau ua raws li qhov txiaj ntsig ntawd.
Thaum twg cov tshuaj tiv thaiv thermite tiav lawm, cov hlau uas tsim los yog dab tsi?
Cov tshuaj tiv thaiv thermite yog cov tshuaj tiv thaiv oxidation-txo qis zoo ib yam li qhov hluav taws kub ntawm cov hmoov dub. Cov tshuaj tiv thaiv yuav tsum muaj hlau oxide thiab roj. Cov roj hauv cov tshuaj tiv thaiv thermite koj tsim yog txhuas hauv cov ntawv ci.
Yuav dej ntsev corrode galvanized hlau?
Cov dej ntshiab ib puag ncig muaj ob lub ntsiab lus tseem ceeb rau categorizing corrosion muaj peev xwm: dej tawv thiab mos. … Yog li ntawd, yam koj muaj yog ib txoj cai dav dav uas cov dej mos hnyav heev corrodes kub-dip galvanized steel thaum cov dej tawv tsis.
