Cov tswv yim siv los txheeb xyuas cov neeg tsim khoom lag luam muaj txiaj ntsig Ceramic: Kev Ntsuam Xyuas Cov Khoom Siv, Craftsmanship, Thiab Qhov Tseem Ceeb Zoo

Ceramic bases yog cov khoom tsim los ntawm cov khoom siv ceramic uas feem ntau ua haujlwm xws li kev txhawb nqa, rwb thaiv tsev, kev sib txuas, lossis kev tiv thaiv; lawv tau siv dav hauv cov khoom siv hluav taws xob, cov cuab yeej tswj qhov kub thiab txias, thiab cov khoom siv davhlau ya nyob twg. Lub chaw tsim khoom muaj peev xwm ntawm cov khoom siv ceramic feem ntau txhais tau tias yog ib lub lag luam uas muaj cov ntaub ntawv paub tab, cov txheej txheem tsim khoom, thiab kev tswj xyuas zoo. Cov tuam txhab lag luam no feem ntau ua raws li cov khoom lag luam, thiab kev ua haujlwm ntawm lawv cov khoom ncaj qha cuam tshuam rau kev ntseeg siab thiab kev pabcuam lub neej ntawm cov khoom siv hauv qab.

 

Txhawm rau nkag siab txog cov peev txheej tsim khoom rau cov hauv paus ceramic, ib qho yuav tsum xub nkag siab txog cov ntaub ntawv koom nrog. Nyob ntawm daim ntawv thov, ceramic bases yuav ua los ntawm cov ntaub ntawv xws li alumina, zirconia, steatite, cordierite, los yog corundum-mullite ceramics. Alumina ceramics muaj lub zog txhua yam thiab zoo heev rwb thaiv tsev, ua rau lawv haum rau cov qauv hluav taws xob hauv paus; zirconia ceramics feature zoo toughness, ua rau lawv zoo tagnrho rau cov khoom uas yuav tsum tau muaj feem xyuam; steatite ceramics pom qhov tsis tshua muaj dielectric poob thiab feem ntau siv nyob rau hauv siab - zaus lossis precision hluav taws xob ib puag ncig; cordierite ceramics muaj cov coefficient tsawg ntawm thermal expansion thiab tiv thaiv thermal shock, ua rau lawv haum rau cov hauv paus nyob ze cov cua sov. Yog li ntawd, kev xaiv cov khoom siv yog qhov taw qhia tseem ceeb thaum ntsuas tus neeg tsim khoom txoj hauv kev.

 

Hais txog kev tsim khoom, cov tuam txhab muaj peev xwm feem ntau muaj peev xwm ua tiav hauv kev npaj hmoov, sib sau, sintering, thiab tom qab- ua. Hmoov particle loj tis thiab granulation zoo ncaj qha cuam tshuam qhov ntom ntawm "ntsuab lub cev" (tsis muaj hluav taws xob ib feem) thaum lub sij hawm qhuav nias, thaum kub siab casting yog haum rau cov hauv paus nrog cov ntaub ntawv nyuaj. Kub profiles thiab huab cua tswj thaum lub sij hawm sintering txiav txim siab qhov ntom ntawm lub cev ceramic thiab seb puas muaj deformation lossis tawg tshwm sim. Cov tuam txhab lag luam ntseeg siab feem ntau tsim cov txheej txheem kev khiav hauj lwm rau cov theem no thiab ua haujlwm hauv - cov txheej txheem tshuaj xyuas kom txo qis batch - rau - batch variation.

 

Los ntawm kev tswj xyuas qhov zoo, kev ntseeg siab ntawm cov hauv paus ceramic tuaj yeem raug soj ntsuam thoob plaws ntau qhov ntev. Thawj yog qhov tsos: cov khoom yuav tsum tsis muaj qhov pom tseeb pinholes, me ntsis, los yog tawg thiab muaj xim zoo ib yam. Qhov thib ob yog qhov tseeb qhov tseeb: kam rau ua rau qhov chaw mounting thiab qhov chaw yuav tsum ruaj khov. Qhov thib peb yog kev ua tau zoo, npog rwb thaiv tsev tsis kam, dielectric zog, kub tsis kam, thiab mechanical zog. Cov kev ntsuas no yuav tsum muaj cov cuab yeej ntsuas kev tshaj lij es tsis yog kev tshuaj xyuas qhov muag; Yog li, muaj peev xwm kuaj tau yog ib qho cim ntawm lub chaw tsim khoom muaj peev xwm.

 

Kev paub txog kev siv cov hauv paus ceramic kuj tsim nyog sau cia. Thaum sib dhos, yuav tsum tau saib xyuas kom tsis txhob muaj ntug kev puas tsuaj los ntawm kev cuam tshuam sab nraud. Txawm hais tias cov ntaub ntawv ceramic muaj cua sov- tiv taus, qhov kub thiab txias hloov pauv sai tuaj yeem ua rau thermal shock tawg; Yog li ntawd, cov khoom siv nrog thermal expansion coefficients yuav tsum raug xaiv rau siab - khoom siv fais fab. Hauv kev siv txhua hnub, qhov ntev - lub sij hawm txuam nrog cov plua plav lossis cov dej noo tuaj yeem ua rau cov rwb thaiv tsev ua haujlwm tsis zoo, yog li kev tu thiab ua kom cov khoom kom qhuav yuav pab tswj lawv txoj haujlwm.

 

Los ntawm kev xav hauv kev lag luam, kev tsim cov ceramic mounts poob rau hauv thaj tsam ntawm kev tsim khoom lag luam, qhov kev txawj ntse yog qhov tseem ceeb tshaj li kev lag luam lag luam. Lub chaw tsim khoom lub zog yog feem ntau cuam tshuam los ntawm nws txoj kev nkag siab ntawm cov khoom tsim, kev paub ntau ntxiv hauv kev ua cov txheej txheem, thiab kev ua haujlwm rau cov teeb meem zoo, tsis yog txhais los ntawm qhov ntsuas ntawm kev ua haujlwm. Yog li ntawd, kev ntsuam xyuas lub chaw tsim khoom muaj peev xwm yuav tsum muaj kev ntsuam xyuas ntau yam xws li cov khoom siv, kev siv thev naus laus zis, kev kuaj muaj peev xwm, thiab kev pabcuam; ib tug yuav tsum tsis txhob cia siab rau tus nqi quotes los yog qhov muag pom ntawm cov qauv.

 

Hauv cov ntsiab lus, raws li cov khoom tseem ceeb, qhov zoo ntawm ceramic mounts yog txiav txim siab ntawm txhua theem ntawm kev tsim khoom, los ntawm cov khoom siv raw mus rau qhov kawg sintering txheej txheem. Kev nkag siab txog cov khoom siv, cov txheej txheem tsim khoom, thiab cov ntsiab lus tseem ceeb ntawm kev tswj xyuas zoo ua rau muaj kev ntsuam xyuas tseeb dua ntawm cov chaw tsim khoom lub peev xwm. Los ntawm lub hom phiaj kev xav, lub zog tsis yog pob khawm ntawm ib qho kev txwv tab sis yog qhov tshwm sim ntawm kev muaj peev xwm ua tau zoo.
