Dab tsi yog qhov smelting ntawm malleable steel yeeb nkab castings?
May 12, 2023
Kub-dip galvanizing yog ib txwm txheej txheem ntawm malleable steel yeeb nkab fittings hauv Hongma Steel Casting Company. Nws hloov dua siab tshiab rau electroplating tsis yog tsuas yog ib qho tseem ceeb hloov nyob rau hauv txoj kev plating, tab sis kuj yog ib qho kev tshwm sim ntawm tus nqi qis, txhim kho ib puag ncig ntau lawm, thiab yooj yim tshem tawm cov pa phem. Txij li cov malleable steel yeeb nkab fittings yog malleable cam khwb cia hlau nrog complex muaj pes tsawg leeg thiab xoob qauv, muaj ntau yam xws li shrinkage kab noj hniav, pores thiab hlwv nyob rau hauv thiab nyob rau saum npoo ntawm substrate. Nyob rau tib lub sij hawm, hlau oxide zaj duab xis yog yooj yim tsim rau ntawm qhov chaw, uas ua rau kom qhov nyuaj ntawm electroplating.
Tam sim no, galvanizing ntawm malleable steel yeeb nkab fittings yog qhov txheej txheem no. Qhov kom zoo dua ntawm cov poov tshuaj (sodium) ntsev-plated malleable steel yeeb nkab fittings yog tias cov txheej txheem zoo dua li dip-plating ci rib hlau, thiab cov nqi tsim khoom tau txo qis. Qhov tsis zoo yog tias nws tsis yooj yim rau kev tsim cov txheej txheem ntawm cov phab ntsa sab hauv ntawm lub raj, thiab qhov saum npoo ntawm lub raj yog yooj yim hloov xim, uas cuam tshuam rau kev tiv thaiv txheej. Hlau impurities yog ib qho kev txhawj xeeb rau yav tom ntej. Yog tias lawv tsis kho txhua lub hlis, lawv yuav cuam tshuam rau kev tsim khoom ib txwm muaj. Chloride ci zinc-hlau platform kub electroplating txheej txheem tswj kev tiv thaiv kev ua haujlwm ntawm kub-dip plating, txhim kho qhov zoo ntawm cov poov tshuaj (sodium) ntsev galvanizing, thiab ua rau qhov tsis txaus ntawm cov txheej txheem no. Qhov zoo thiab qhov tsis zoo ntawm cov txheej txheem qhia txog kev txhim kho tshiab ntawm kev tiv thaiv electroplating technology. Tshwj xeeb, zinc-hlau alloys yog nyiam los ntawm cov yeeb nkab fittings electroplating manufacturers tom qab lawv tig cov hlau impurities uas nyuaj rau kev daws teeb meem hauv galvanizing rau hauv cov txiaj ntsig. Zinc-hlau alloy yog lub npe hu ua cov txheej txheem zoo tshaj plaws los hloov galvanized yeeb nkab fittings yam tsis muaj kuab paug.
Los ntawm txoj kev loj hlob ntawm kev kho deg ntawm malleable steel yeeb nkab fittings, kev hloov pauv los ntawm kub-dip plating rau electroplating tej zaum yuav yog yav tom ntej kev taw qhia. Nws yog inevitable nyob rau hauv cov kev taw qhia no los hloov galvanized steel yeeb nkab fittings nrog zinc-hlau platform. Kev ua tau zoo ntawm lub thoob plating yog siab dua li ntawm khib plating. ib qho tshwm sim tsis tau.
