tooj dag
Kev siv tooj dag thiab tooj liab hnub rov qab mus rau ntau pua xyoo, thiab niaj hnub no yog siv rau hauv qee qhov kev siv thev naus laus zis tshiab thiab kev siv thaum tseem siv yog ntau cov ntawv siv xws li cov twj paj nruag, tooj dag eyelets, ornamental khoom thiab kais thiab qhov rooj kho vajtse.
Brass yog dab tsi?
Brass yog ib qho alloy ua los ntawm kev sib xyaw ntawm tooj liab thiab zinc los tsim cov ntaub ntawv nrog ntau yam kev siv engineering. Brass muaj pes tsawg leeg muab cov hlau melting point haum rau ntau daim ntawv thov, nrog rau tsim nyog rau kev koom nrog siv cov txheej txheem brazing. Lub melting point ntawm tooj dag yog qis dua tooj liab nyob ib ncig ntawm 920 ~ 970 degrees Celsius nyob ntawm seb tus nqi ntawm Zn ntxiv. Brass melting point yog qis dua tooj liab vim yog ntxiv Zn. Brass alloys tuaj yeem sib txawv hauv Zn muaj pes tsawg leeg los ntawm tsawg li 5% (feem ntau hu ua Gilding Metals) mus rau ntau dua 40% raws li siv hauv machining tooj dag. Ib lo lus uas tsis tshua siv yog tooj dag bronze, qhov twg qee qhov ntxiv ntawm tin yog siv.
Dab tsi yog tooj dag siv rau?
tooj dag muaj pes tsawg leeg thiab ntxiv zinc rau tooj liab nce lub zog thiab muab ntau yam ntxwv, uas ua rau cov tooj dag yog ntau yam khoom siv. Lawv yog siv rau lawv lub zog, corrosion kuj, tsos thiab xim, thiab yooj yim ntawm kev ua hauj lwm thiab koom. Ib theem alpha tooj dag, muaj txog li 37% Zn, yog cov ductile heev thiab yooj yim rau kev ua haujlwm txias, weld thiab braze. Lub dual theem alpha-beta brasses feem ntau yog ua haujlwm kub.
Puas muaj ntau tshaj ib qho tooj dag muaj pes tsawg leeg?
Muaj ntau ntau cov tooj dag nrog ntau qhov sib txawv thiab cov yam ntxwv tshwj xeeb rau kev siv tshwj xeeb los ntawm qib sib ntxiv ntawm zinc. Qib qis ntawm Zn ntxiv feem ntau hu ua Guilding Hlau lossis Liab Brass. Thaum cov qib siab ntawm Zn yog cov alloys xws li Cartridge Brass, Dawb Machining Brass, Naval Brass. Cov brasses tom qab no kuj muaj qhov sib ntxiv ntawm lwm cov ntsiab lus. Qhov sib ntxiv ntawm cov hlau lead rau tooj dag tau siv ntau xyoo los pab lub machinability ntawm cov khoom los ntawm inducing chip so point. Raws li qhov kev pheej hmoo thiab kev phom sij ntawm cov hlau lead tau pom tau tias nws tsis ntev los no tau hloov nrog cov khoom xws li silicon thiab bismuth kom ua tiav cov yam ntxwv zoo sib xws. Cov no tam sim no paub tias yog cov hlau lead uas tsis muaj hlau lead lossis cov hlau lead dawb.
Puas muaj lwm yam ntxiv?
Yog lawm, me me ntawm lwm yam alloying ntsiab kuj tseem yuav ntxiv rau tooj liab thiab tooj dag. Commons piv txwv yog txhuas rau tshuab-muaj peev xwm raws li tau hais los saum no, tab sis kuj arsenic rau corrosion kuj mus dezincification, tin rau lub zog thiab corrosion.
Brass Xim
Raws li cov ntsiab lus zinc nce, cov xim hloov. Qhov qis Zn alloys feem ntau zoo li tooj liab hauv cov xim, thaum lub siab zinc alloys zoo li kub lossis daj.
