Tooj daj
Kev siv tooj dag thiab cov tsev tooj liab qab ntau pua xyoo thiab cov ntawv siv suab paj nruag xws li cov khoom siv suab paj nruag xws li cov khoom siv suab paj nruag, khoom siv dag thiab coj mus rhaub thiab cov khoom siv.
Dab tsi yog tooj dag ua los ntawm?
Tooj dag yog ib qho alloy ua los ntawm kev sib xyaw ntawm tooj liab thiab zinc los tsim cov khoom siv nrog ntau hom kev siv tshuab. Brass muaj pes tsawg leeg muab cov hlau melting taw tes haum rau ntau daim ntawv thov, suav nrog tsim nyog rau kev koom nrog kev siv cov txheej txheem brazing. Lub ntsiab lus melting ntawm tooj dag yog qis dua tooj liab nyob ib ncig ntawm 920 ~ 970 degrees Celsius nyob ntawm tus nqi ntawm ZN ntxiv. Tooj dag melting point yog qis dua li ntawd ntawm tooj liab vim yog cov ntxiv ZN. Tooj dag alloys tuaj yeem sib txawv nyob rau hauv ZN muaj pes tsawg leeg los ntawm tsawg li 5% (ntau dua uas tau hais txog cov hlau nplaum) rau ntau dua 40% raws li siv nyob rau hauv lub tshuab luam ntawv. Ib qho tsis tshua muaj hnub siv yog tooj dag bronze, qhov twg ntxiv ntawm tin yog siv.
Dab tsi yog tooj dag siv rau?
Tooj dag muaj pes tsawg leeg thiab qhov sib ntxiv ntawm zinc mus rau tooj liab thiab muab ntau yam ntawm cov yam ntxwv, uas yog ntau yam khoom siv. Lawv siv rau lawv lub zog, corrosion tsis kam, tsos thiab xim, thiab yooj yim ntawm kev ua haujlwm thiab koom nrog. Lub theem alcha brasses, muaj txog li ntawm 37% zn, yog cov du cus heev thiab yooj yim rau kev ua haujlwm txias, weld thiab barl. Lub dual theem alpha-beta brasses feem ntau yog kub ua haujlwm.
Puas muaj ntau dua ib qho tooj dag muaj pes tsawg leeg?
Muaj ntau ntau brasses nrog cov kev sib txawv thiab cov yam ntxwv ua kom haum rau cov ntawv thov tshwj xeeb los ntawm qib ntawm kev sib ntxiv ntawm cov kev sib ntxiv ntawm cov kev sib ntxiv ntawm zinc. Qeb qis dua ntawm ZN ntxiv yog feem ntau hu ua guilding hlau lossis tooj liab liab. Thaum cov qib siab dua ntawm cov ZN yog cov alloys xws li Cartridge tooj dag, dawb machining tooj daj, naval tooj dag. Cov brasses tom qab no tseem muaj qhov sib ntxiv ntawm lwm cov ntsiab lus. Qhov sib ntxiv ntawm cov hmoov txhuas tau siv rau ntau xyoo rau kev sau cov tshuab ntawm cov khoom los ntawm kev ua yuam kev cov ntsiab lus. Raws li kev pheej hmoo thiab kev phom sij ntawm cov hmoov txhuas tau raug pom tau tias nws tau hloov tshiab xws li silicon thiab bismuth kom ua tiav kev tes dag zoo sib xws. Cov no yog tam sim no paub tias cov txhuas cov hmoov txhuas lossis txhuas dawb.
Lwm tus tau ntxiv?
Yog lawm, cov khoom siv hluav suav me me yuav muab ntxiv rau tooj liab thiab tooj dag. Cov qauv ua piv txwv yog ua rau lub tshuab muaj peev xwm tau hais los saum toj no, tab sis kuj arsenic rau corrosion tsis kam, tin rau lub zog thiab corrosion.
Nrig Brass Xim
Raws li cov ntsiab lus zinc yog nce, cov xim hloov. Cov alloys tsawg zaus tuaj yeem sib zog kho tus tooj liab hauv cov xim, thaum lub siab zinc zoo tshwm sim kub lossis daj.
