Tswj kev tsim thiab Sintering txheej txheem rau Ceramic Insulators

Insulators feem ntau yog tsim los ntawm cov txheej txheem ntub dej hydraulic los yog isostatic nias txheej txheem. Ob txoj hauv kev kom ntseeg tau tias cov hmoov ceramic yog raug rau cov siab sib xws hauv cov pwm, uas ua rau muaj qhov siab - ntom ntom ntsuab. Isostatic nias, tshwj xeeb, yog qhov zoo rau cov insulators nrog cov duab nyuaj lossis qhov loj me; nws tau lees tias tsis sib xws siab faib thoob plaws txhua ntu, yog li tiv thaiv qhov sib txawv ntawm qhov sib txawv uas tuaj yeem ua rau muaj kev ntxhov siab sab hauv lossis deformation tom qab sintering.

 

Sintering yog ib theem tseem ceeb hauv kev tsim cov khoom siv ceramic. Cov neeg tsim khoom tau sau cov kev txawj ntse hauv kev tswj cov qhov cub kub thiab cov cua. Kev siv cov khoom siv hluav taws xob niaj hnub los yog cov chaw nres tsheb ciav hlau ua kom muaj kev tswj xyuas meej ntawm cov cua kub nkhaus, tuav lub sij hawm, thiab cov nqi cua txias. Cov txheej txheem cua sov qeeb, tswj tau yooj yim tshem tawm cov dej noo thiab decomposition ntawm cov organic teeb meem hauv lub cev ntsuab, tiv thaiv kev tawg. Thaum lub sij hawm siab -kub theem, lub sij hawm tuav txaus kom paub meej cov khoom zoo- xeev cov tshuaj tiv thaiv ntawm cov khoom siv ceramic, tsim kom muaj zog inter- particle bonding. Thaum kawg, lub qhov dej zoo-tsim lub caij txias txias tau zoo tshem tawm cov kev ntxhov siab thermal thiab tiv thaiv cov khoom los ntawm nkig dhau lawm. Qhov kev tswj xyuas zoo tshaj plaws ntawm tag nrho cov txheej txheem sintering yog qhov tseem ceeb los ua kom cov khoom lag luam zoo.
