Dab tsi yog qhov siab tshaj plaws sintering kub? Cov Ntsiab Lus Tseem Ceeb thiab Ranges piav qhia

Qhov kub tshaj plaws rau Sintering nyob ntawm cov ntaub ntawv, khoom siv thiab cov txheej txheem siv. Direct Sintering tuaj yeem ncav cuag qhov kub li 3000 degree, thaum tus qauv Sintering rapaces feem ntau muaj nyob ntawm 1120 degree thiab 1800 degree. Siab kub sintering yog feem ntau siv rau cov hlau sintering thiab tuaj yeem ncav cuag txog 2050 degree f (1121 degree) lossis siab dua, nyob ntawm cov khoom uas xav tau. Yam khoom xws li cov ntaub ntawv muaj pes tsawg leeg, qhov loj me me thiab sintering cua kuj cuam tshuam rau qhov kub siab tshaj plaws uas tuaj yeem ua tiav. Qhov kev xaiv ntawm qhov kub yog qhov tseem ceeb rau kev ua kom zoo densification, cov khoom siv mechanies thiab tus nqi ua tau zoo.

Dab tsi yog qhov kub tshaj plaws rau sintering? Cov Ntsiab Lus Tseem Ceeb thiab Ranges
Ntau tshaj plaws Sinterging Kub Ntau Yam:

Direct Sintering: Qhov ntsuas kub txog 3000 degree siab yog hais txog hauv cov ntawv pov thawj. Hom no yog tsim nyog rau cov ntaub ntawv tshwj xeeb uas yuav tsum muaj kub heev.
Txheem Sintering Furnaces: Feem ntau ntawm 1120 Degree thiab 1800 Qib raws li ntawm Kiln tsim thiab cov khoom yuav tsum tau ua.
Kev ntsuas kub siab: Siv cov hlau, tshwj xeeb tshaj yog cov hlau ua kom hnyav, ntawm qhov kub thiab txias txog 2050 degrees Fahrenheit (1121 degrees Celsius) lossis siab dua. Tus txheej txheem no txhim kho cov khoom siv me txhua yam xws li lub zog tensile thiab qaug zog tsis kam.
Yam cuam tshuam rau qhov siab tshaj plaws sinining kub:

Cov Khoom Siv Khoom Siv: cov khoom sib txawv muaj cov kev xav tau yooj yim tshaj plaws. Piv txwv li, ceramics thiab cov hlau feem ntau yuav tsum tau kub dua li cov polymers.
Cov peev txheej siv tau: Hom ntawm cov cub tawg (conghab, pusher, lossis nws cov kev ua haujlwm siab tshaj plaws uas tuaj yeem ua tiav.
Cov huab cua: Sintering nyob rau hauv lub nqus dej lossis iner roj (xws li argon lossis nitrogen) tuaj yeem ua tiav qhov siab dua cua ntau dua li huab cua vim tias nws tiv thaiv oxidation thiab paug.
Ntxim Kub Kub ntawm Sintering Cov Ntsiab Lus:

Quav ntom ntom: ntau qhov kub siab ua rau cov kev sib tw uas muaj zog ntawm cov khoom thiab cov porosity sab hauv, uas txhim kho qhov ntawj ntom.
Cov cuab yeej kho tshuab: nce kub txhim kho tensile lub zog, flexural qaug zog, tab sis kuj tseem tuaj yeem ua rau cov nyom loj lossis theem kev hloov pauv.
Tus nqi thiab lub zog kub uas yuav tsum muaj lub zog ntau dua thiab cov khoom siv siab dua, uas nce cov nqi ua haujlwm ntau dua.
Kev lag luam tawm thiab cov kev txiav txim siab:

Cov khoom siv tsis haum: kev kub heev tuaj yeem ua rau cov khoom siv tsis tau, xws li theem hloov pauv lossis tsis xav tau.
Txheej Txheem Tswj: Kev tswj kom sov, cua sov tus nqi, thiab tus ntsuas cua txias yog qhov tseem ceeb rau kev ua kom tiav yam tsis muaj qhov tsis xws luag.
Economic Finibility: Kev kub siab sintering yog kim kim dua vim muaj hluav taws xob ntau siv thiab cov khoom siv hnav.
Cov Ntawv Thov Siv:

Cov hlau: Kev siv kub-kub tau siv rau cov hlau, hlau, thiab lwm cov alloys kom nce lub zog thiab kav ntev.
Ceramics: Sinining ntawm huab cua sov heev (txog 3000 degree) cov txiaj ntsig hauv cov ceramics tau siv hauv aerospace thiab electronics.
Polymers: polymers tuaj yeem yog sintered ntawm qis dua kub, feem ntau hauv qab 300 degree.
Hauv cov ntsiab lus, qhov siab tshaj plaws sintering kub vary nyob ntawm cov khoom siv, khoom siv, thiab txheej txheem tseev kom muaj. Nkag siab txog cov xwm txheej no yog qhov tseem ceeb rau kev ua kom ua tiav cov txiaj ntsig kev ua tiav thiab ua tiav cov khoom siv uas xav tau.
