Lub tshuab nqus tsev sintering rauv yog lub cub hluav taws xob tshwj xeeb uas ua kom sov cov ntaub ntawv hauv qhov chaw tswj, tsis tshua muaj siab - qhov chaw siab, tsis yog qhib cua.
Nws lub luag haujlwm tseem ceeb yog fuse cov khoom siv hmoov rau hauv cov khoom ntawm qhov kub thiab txias thaum tiv thaiv lawv los ntawm kev ua pa nrog oxygen lossis lwm yam pa cua. Cov txheej txheem no tiv thaiv kev kis kab mob thiab oxidation, ua rau cov khoom siv nrog ntau dua purity, ntom, thiab kev ua haujlwm.
Qhov tseem ceeb yog lub tshuab nqus tsev vacuum tsis yog cua sov xwb; nws yog hais txog kev tswj hwm ntawm cov cua hauv qhov cub.
Los ntawm kev tshem tawm cov huab cua, cov tshuaj tsis xav tau xws li oxidation raug tshem tawm, ua rau cov khoom siv siab heev uas tsis tuaj yeem tsim nyob rau hauv cov tsoos furnaces.
Vim li cas Nqus Tsev yog qhov tseem ceeb
Lub ntsiab feature ntawm no technology yog lub nqus tsev vacuum. Qhov kub siab xav tau rau sintering ua rau feem ntau cov ntaub ntawv muaj zog heev. Lub tshuab nqus tsev ib puag ncig ncaj qha daws qhov teeb meem tseem ceeb no.
Tshem tawm oxidation thiab paug
Nyob rau hauv ib puag ncig atmospheric, cov ntaub ntawv cua sov ua rau lawv hnov mob nrog oxygen, tsim ib txheej oxide. Qhov oxidation no tsis muaj zog rau kev ua haujlwm ntawm cov khoom kawg thiab tuaj yeem hloov kho nws cov khoom.
Los ntawm kev tsim lub tshuab nqus tsev, lub cub tawg chamber tshem tawm tag nrho cov pa oxygen thiab lwm yam reactive gases, yog li khaws cia cov tshuaj lom neeg ntawm cov khoom.
Ua tiav Precise Control
Lub tshuab nqus tsev ib puag ncig muab kev huv, nruab nrab hauv paus. Qhov no tso cai rau cov neeg ua haujlwm tswj hwm lub xeev lub tshuab nqus tsev ntshiab lossis txhob txwm ua kom paub cov khoom siv siab tshaj -purity inert gases, xws li argon. Kev tswj hwm qib no yog qhov tseem ceeb rau kev ua tiav cov khoom siv tshwj xeeb.
Txhim kho cov khoom purity thiab ntom
Tsis muaj kev cuam tshuam los ntawm cov pa cua hauv huab cua, cov khoom siv tuaj yeem sib txuas tau zoo dua. This results in a denser, stronger final product, avoiding the tiny voids and impurities that can form during atmospheric heating.
Qauv ntawm aNqus Sintering Rauv
Lub tshuab nqus tsev vacuum yog ib qho kev ua haujlwm uas muaj ntau yam tseem ceeb ua haujlwm ua ke los tswj qhov kub thiab txias nrog qhov tseeb heev.
Vacuum Chamber thiab Vaj Tsev
Qhov no yog lub kaw lus tseem ceeb thiab ruaj khov ntawm lub cub tawg. Nws yog tsim los tiv thaiv qhov kub sab hauv thiab lub zog sab nraud tsim los ntawm lub tshuab nqus tsev. Ib qho dej-qhov cua txias feem ntau yog muab tso rau hauv lub qhov cub kom tsis txhob muaj cua sov.
Cua sov System (Hot Zone)
Nyob rau hauv lub chamber, thaj chaw kub muaj cov cua sov uas tsim kom muaj qhov kub thiab txias.
Cov ntsiab lus no tuaj yeem ua los ntawm graphite lossis refractory hlau thiab ua kom sov cov khoom siv xws li cov cua kub tsis kam lossis induction cua sov.
Lub tshuab nqus tsev twj tso kua mis
Qhov no yog lub hauv paus tseem ceeb ntawm lub qhov cub qhov cua tswj. Nws feem ntau muaj cov twj tso kua mis- feem ntau yog lub twj tso kua mis sib xyaw ua ke nrog lub siab - lub tshuab nqus tsev twj (xws li lub twj tso kua mis diffusion lossis turbomolecular twj tso kua mis)- uas ua hauj lwm ua ke kom khiav tawm cua los ntawm lub combustion chamber, yog li ua tiav lub hom phiaj qis - lub xeev siab
Tswj System
Nyob rau hauv lub plawv ntawm lub cub tawg yog ib tug sophisticated electronic system uas tswj txhua theem ntawm tag nrho cov txheej txheem. Nws tswj cov cua kub kom meej, tswj cov khoom ntawm qhov kub thiab txias (lub npe hu ua "soaking"), tswj cov cua txias, thiab tswj lub tshuab nqus tsev.
