Ntau lawm Technology Ntawm Composite Ceramic Evaporation Nkoj
Dec 10, 2021
Lub nkoj sib xyaw ceramic evaporation feem ntau yog siv rau hauv kev tsim cov txheej hauv kev lag luam ntim khoom kuj tseem tuaj yeem siv rau hauv kev lag luam sib xyaw ua ke txheej txheej teeb, tsis muaj qhov tsis ntseeg tias cov khoom sib xyaw ceramic evaporation nkoj yog lub zog tseem ceeb ntawm kev lag luam txhuas plating. Kev siv dav dav, cov hauv qab no yog los piav qhia txog kev tsim cov thev naus laus zis ntawm kev sib xyaw ceramic evaporation nkoj.
Evaporation nkoj khoom siv cov cuab yeej tsim khoom yog" kub nias sintering". Cov cuab yeej tsim khoom no yog hais txog kev sintering ntawm lub cev nyob rau hauv qhov kub thiab txias siab, thiab molding thiab firing ntawm lub cev yog ua tiav tib lub sijhawm.
Tam sim no, qhov kub ntawm cov khoom tiav hauv Suav teb yog nyob nruab nrab ntawm 1700-1900 ℃, thiab qhov kub ntawm lub tshuab hluav taws xob tshiab tuaj yeem ncav cuag ntau dua 2300 ℃. Nyob rau hauv cov xwm txheej no, lub nkoj evaporation yog qhov zoo. Nws tau raug pov thawj tias lub nkoj evaporation tsim nyob rau hauv America tshiab yog rhuab mus rau 1900 ℃. Kev txhim kho ntawm qhov kub thiab txias rau cov khoom hauv cov txheej txheem ntawm sintering (kub nias) kom qhov ceev ntawm lub cev yog siab dua, koj tuaj yeem tau txais cov khoom tsis muaj qhov porosity, kom cov khoom los tiv thaiv bending anti-seismic evaporation kis thiab lwm yam khoom, vim hais tias lub evaporation nkoj lub cev ntsuas yog feem ntau yog ob, ceev thiab resistivity. Nyob rau hauv tus txheej txheem ntawm kev siv yuav tsum muaj tus coj ntom ntom thiab coj resistivity.
Kev ua haujlwm kub ntawm cov khoom sib xyaw ceramic evaporation nkoj hauv lub tshuab nqus tsev yog feem ntau txog 450 ℃, thiab kev pabcuam lub neej ntawm lub nkoj evaporation dav dav yog 12 txog 15 teev.
Hauv kev tsim cov evaporation nkoj, BN, TiB2, ALN raws li ib qho kev faib ua feem ntawm tempered rau hauv pwm, kub thiab siab siab, thiab tom qab ntawd, tos kom txias pwm, molding khoom rau txiav khiav-hauv, peb yuav tsum tsim boron. nitride ceramic - cov khoom siv ceramic evaporation nkoj.
