Khoom Taw qhia
Machinable Glass Ceramic los ntawm UNIPRETEC zoo ib yam li qeb Macor. Peb Mica-based machinable ceramic khoom muab cov adaptability ntawm cov ua tau zoo polymer, qhov yooj yim machining ua haujlwm-muaj peev xwm ntawm cov hlau, thiab cov khoom qib siab ntawm ib qho kev ua lag luam zoo. Nws yog cov iav mica-based iav-ceramic uas muaj cov khoom sib txawv tsis tshua muaj los ntawm ob tsev neeg cov ntaub ntawv. Hauv kev nkag siab dav dav, iav mica ceramic yog cov hluav taws xob thiab thermal ua tau zoo thiab tshwj xeeb zoo rau hauv daim ntawv thov nyob rau hauv qhov kub thiab txias, nqus tsev, thiab qhov chaw tsis muaj teeb meem.
Kev siv cov cuab yeej hlau nquag los ua cov tshuab machining yog ib qho ntawm cov txiaj ntsig tseem ceeb ntawm mica iav ceramic. Nws yog li ntawd txhais tau tias tsis muaj kev txwv rau ntau lub sijhawm ntawm tus qauv tuaj yeem tsim thiab cov nqi tsim khoom qis dua qis dua nrog lwm cov kev txua ntoo txau, ua nws qhov kev xaiv zoo tshaj plaws rau ob qho thaum pib ntawm kev txhim kho thiab nruab nrab-ntau lawm khiav.
MGC machinable ceramic yog qhov muaj zog. nws yuav tsis keej lossis deform zoo li polymer kub. Nws muaj qhov tsawg kawg nkaus porosity thiab tuaj yeem ua polished rau saum npoo ntawm 0.2 micrometers.
Vim tias nws cov cua sov ua kom ruaj khov, siv tau mica-based iav ceramic yuav tseem tsis nkag lossis deform, txawm tias nyob hauv qab kub. Nws muaj cov khoom cua sov qis, ua rau nws haum rau siv raws li cov kub siab. rwb thaiv tsev. Thiab nws qhia tau zoo tshaj plaws qhov kev nyab xeeb nyob rau hauv ib puag ncig ntawm ib puag ncig kev mob (tshav kub, hluav taws xob, thiab lwm yam). Nws cov coefficient ntawm thermal expansion yog ze heev ntawm lwm cov hlau thiab cov iav tsom iav.
Kev ntsuas hluav taws xob ua tau zoo ntawm iav mica ceramic yog qhov tshwj xeeb tshaj yog thaum muaj kev sov siab. mob. Nws yog qhov zoo thaum ua ntawv thov rau cov kev ntsuas siab nrog ntau yam ntawm cov zaus thiab qhov ntev. Tsis tas li ntawd, cov khoom siv no kuj tiv taus hluav taws xob.
