Kev sib xyaw ntawm impurities yuav cuam tshuam rau cov khoom hluav taws xob ntawm cov plooj (porcelain).
Cov qauv kev lag luam hluav taws xob xyoo 2001 SJ/T11260-2001 ntawm Cov Neeg Tuam Txhab Tuam Txhab Tuam Txhab Tuam Txhab muab cov kev kam rau siab ntawm txoj kab uas hla, flatness thiab roundness ntawm ceramic casing ntawm lub tshuab nqus tsev hloov yeeb nkab. Peb lub Hoobkas kuj tau tsim cov qauv tshuaj ntsuam xyuas raws li tus qauv no. Feem ntau, tsuas yog 5% ntawm cov neeg tsim khoom tsim nyog hauv peb lub Hoobkas tsis tsim nyog rau qhov loj thiab cov duab, thaum tsis tsim nyog tus nqi ntawm qee cov tuam txhab yog siab li 30% mus rau 40%, thiab qhov loj me yog qhov tsis sib xws thiab qhov sib xws tsis zoo. Qhov sib txawv ntawm qhov loj thiab cov duab yuav ua rau muaj teeb meem rau kev sib dhos, tshwj xeeb tshaj yog rau cov neeg tsim khoom siv cov txheej txheem sib khi ib zaug, thiab faus zais qhov phom sij rau kev lees paub ntawm coaxiality thiab huab cua nruj ntawm tag nrho cov raj, yog li txo qhov kev ntseeg tau ntawm cov khoom. Txhawm rau kom ntseeg tau qhov tseeb ntawm qhov loj thiab cov duab ntawm cov plooj (porcelain plhaub), nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev tswj hwm thiab kev tswj hwm ntawm txhua tus txheej txheem ntawm kev tsim cov plooj (porcelain), suav nrog cov khoom siv raw, kev npaj slurry, molding, wax paug thiab tua cov txheej txheem. .
Vim tias qhov sealing nto yog qhov tseem ceeb ntawm kev sib khi ntawm cov khoom siv ceramic thiab cov khoom hlau, nws yuav cuam tshuam ncaj qha rau sab hauv zoo ntawm metallization thiab sealing, yog li cov kev cai zoo ntawm sealing nto yog nruj heev. Peb lub Hoobkas xav kom lub ntsej muag sealing tsis pub muaj cov kab nrib pleb, qhov hws, khawb, pits, interlayers, thiab lwm yam. Cov impurities hauv plooj (porcelain) feem ntau yog los ntawm cov khoom siv raw thiab cov txheej txheem. Qee qhov impurities nyob rau hauv oxidizing cua yog xim, xws li Cr2O3, Fe2O3, TiO2, thiab lwm yam, yog li nyob rau hauv lub teeb pom kev liab, daj los yog dub me ntsis, ib co impurities tsis muaj xim.
Kev sib xyaw ntawm cov impurities no yuav cuam tshuam rau cov khoom siv hluav taws xob ntawm cov plooj (porcelain) qhov chaw, ua kom cov dielectric poob thiab txo qhov voltage. Yog li ntawd, porcelain manufacturers yuav tsum nruj me ntsis tswj qhov zoo ntawm raw cov ntaub ntawv thiab cov txheej txheem. Cov saum toj no yog qee qhov teeb meem uas yuav tshwm sim hauv kev tshuaj xyuas ntau lawm, cov no yog qee qhov teeb meem uas cov tuam txhab plooj (porcelain) tuaj yeem tswj tau lossis txhim kho, thiab yuav ua li cas tswj cov teeb meem no yuav tsum tau ua tiag tiag los ntawm cov tuam ntxhab.
