Hauv kev tsim kho niaj hnub no, galvanized hlau thiab qis carbon steel hlau feem ntau siv. Qhov tseeb, qis carbon steel hlau thiab galvanized hlau muaj ntau yam zoo sib xws. Txawm li cas los xij, yog tias koj paub qhov txawv lawv ua tib zoo, koj yuav pom tias lawv tsis tsuas yog sib txawv ntawm cov ntaub ntawv, tab sis kuj tseem muaj qhov sib txawv loj hauv cov yam ntxwv ntawm cov khoom. Yog li ntawd, koj yuav tsum ua kom pom qhov sib txawv ntawm ob qho tib si thaum lub sijhawm yuav khoom. Yog li dab tsi yog qhov txawv ntawm galvanized hlau thiab qis carbon steel hlau? Tus editor yuav qhia nws rau koj hauv qab no.
Tsawg carbon steel hlau: Ua los ntawm carbon structural steel los yog saum toj no, feem ntau tsis galvanized, siv nyob rau hauv machinery thiab springs. Dub, tawv heev; galvanized hlau: ua los ntawm cov pa roj carbon tsawg (me me steel), galvanized, siv rau kev sib txuas thiab qhwv. Dawb thiab mos heev.
Galvanized hlau yog ua los ntawm high-zoo low-carbon steel hlau qws, uas yog kos thiab tsim, pickled thiab xeb-tshem tawm, high-temperature annealed, thiab kub-dip galvanized. Ua los ntawm kev ua kom txias thiab lwm yam txheej txheem. Galvanized hlau muab faib ua kub-dip galvanized hlau thiab txias-dip galvanized hlau (electro-galvanized hlau).
Cov ntsiab lus ntawm cov pa roj carbon tsawg yog tsawg dua {{0}}.2%. Vim tias nws yooj yim rau xeb, qhov saum npoo feem ntau yog galvanized. Nyob rau hauv atmospheric tej yam kev mob, galvanized txheej ntawm galvanized hlau yuav tsis xeb kom txog thaum feem ntau ntawm nws ntog thiab yog kuj mos. Lub npe hu ua "tsawg carbon steel hlau" nyob rau hauv lub neej yog "cov pa roj carbon tsawg carbon steel hlau" nrog cov ntsiab lus ntawm cov pa roj carbon tsawg ntawm 0.6%, lossis "high carbon tsawg carbon steel hlau" nrog cov ntsiab lus carbon ntawm txog 0.8%. Lawv tau raug kho kom sov zoo. Nws muaj txaus hardness thiab elasticity thiab siab zog. Nyob rau hauv cov nqe lus ntawm kev siv, xws li winding dog dig springs, thiab lwm yam.
Qhov sib txawv loj tshaj plaws ntawm galvanized hlau thiab qis carbon steel hlau yog cov ntsiab lus carbon. Cov ntsiab lus carbon ntawm hlau yog ntau dua lossis sib npaug li 2.11%, thaum cov ntsiab lus carbon ntawm cov hlau tsawg dua lossis sib npaug li 2.11%. Hlau-carbon alloys uas muaj cov ntsiab lus ntawm ntau tshaj 2.11% yog cam khwb cia hlau (npua hlau), uas yeej tsis muaj ductility thiab tsis tuaj yeem kos rau hauv Silk. Qhov thib ob, cov ntsiab lus ntawm impurities txawv. Cov ntsiab lus ntawm teeb meem impurities xws li sulfur thiab phosphorus hauv hlau yog me dua. Tsawg carbon steel hlau feem ntau muaj xim xim ntau dua, thaum galvanized hlau muaj xim sib dua thiab dawb.
Cov ntsiab lus saum toj no yog tus editor cov lus qhia rau koj txog qhov sib txawv ntawm galvanized hlau thiab qis carbon steel hlau. Kuv vam tias nws yuav pab tau rau txhua tus neeg yuav khoom thiab siv!
