(1) Qhov zoo ntawm kev ntxiv cov hlau lead rau zinc kua
Ntxiv cov hmoov txhuas rau zinc ua kom luv lub sij hawm melting ntawm zinc, txo qhov yaig ntawm zinc kua ntawm lub lauj kaub galvanizing, yooj yim tshem tawm slag, thiab tiv thaiv cov adhesion ntawm zinc slag rau hauv qab ntawm lub lauj kaub galvanizing. Tsis tas li ntawd, kom tau txais qhov zoo nkauj zoo nkauj ntawm kub-dip galvanized nyias steel daim hlau, txhuas yog ntxiv rau cov kua zinc.
Kev siv cov hmoov txhuas txhim kho qhov ntub dej ntawm zinc kua rau hlau hauv galvanized steel, ua kom muaj kev sib faib ntawm zinc kua rau saum npoo ntawm cov kav dej steel thiab txhim kho qhov zoo nkauj thiab ci ntsa iab ntawm txheej galvanized (hauv cov ntsiab lus ntawm cov txheej txheem ntawm cov txheej txheem. , feem ntau yog 0.2%-0.25%, sib npaug rau cov ntsiab lus ntawm Zn-4 qib). Thaum cov ntsiab lus hlau nyob rau hauv cov kua zinc yog siab, piv txwv li, muaj ntau cov zinc slag, ntxiv ib qho kev tsim nyog ntawm cov hlau lead tuaj yeem txhim kho cov wettability ntawm zinc kua.
(2) Qhov tsis zoo ntawm kev ntxiv cov hmoov txhuas rau zinc kua
Ua ntej, nws txo qhov fluidity ntawm zinc kua. Raws li pom nyob rau hauv daim duab {{0}}, qhov fluidity ntawm zinc kua yog qhov phem tshaj thaum cov ntsiab lus txhuas yog 0.5%, thiab nws tsuas yog rov qab mus rau qib piv rau cov zinc ntshiab thaum cov ntsiab lus txhuas nce mus txog 2%.
Thib ob, thaum cov ntsiab lus txhuas siab dhau lawm, nws tsis tsuas yog ua tsis tau raws li qhov tau hais tseg saum toj kawg nkaus ntawm txheej galvanized tab sis kuj hloov mus rau hauv cov xim grey tsaus. Yog li, cov ntsiab lus txhuas feem ntau txwv rau hauv qab {{0}}.5%. Cov ntsiab lus txhuas feem ntau yog nyob ib ncig ntawm 0.24%, raws li pom nyob rau hauv cov sawb steel galvanizing chav tsev ntawm Wuhan Iron thiab Steel Corporation lub txias dov cog. Tsis tas li ntawd, thaum cov ntsiab lus txhuas hauv txheej galvanized ntau dhau, nws tuaj yeem cuam tshuam rau kev tiv thaiv corrosion; Txawm li cas los xij, qee cov kws tshawb fawb ntseeg tias muaj kev cuam tshuam me ntsis.
