Ua tib zoo xaiv cov khoom siv raw
Sib nrug los ntawm qhov muaj pes tsawg leeg ntawm cov khoom siv ceramic nws tus kheej, optimizing cov txheej txheem tsim khoom thiab tswj cov txheej txheem nruj me ntsis yog qhov tseem ceeb cuam tshuam rau qhov zoo ntawm -voltage ceramic capacitors. Yog li ntawd, thaum xaiv cov khoom siv raw, ib qho yuav tsum xav txog ob qho tib si tus nqi -kev ua tau zoo thiab purity; tshwj xeeb, thaum xaiv cov khoom lag luam ntshiab huv, tshwj xeeb yuav tsum tau them rau lawv qhov tsim nyog rau daim ntawv thov.
Kev npaj ntawm Frit
Qhov zoo ntawm kev npaj frit ho cuam tshuam qhov zoo ntawm cov hmoov ceramic tom qab pob milling nrog rau cov txheej txheem tom ntej firing. Piv txwv li, yog tias frit synthesis kub tsawg dhau lawm, cov synthesis yuav ua tsis tiav, uas yog detrimental rau downstream txheej txheem. Yog tias seem Ca²⁺ ions tseem nyob hauv cov khoom siv hluavtaws, lawv tuaj yeem cuam tshuam cov kab xev -casting (film-forming) txheej txheem. Hloov pauv, yog tias qhov sib xyaw ua ke kub siab dhau lawm, qhov tshwm sim frit yuav nyuaj heev, yog li txo pob -milling efficiency. Tsis tas li ntawd, kev taw qhia ntawm impurities los ntawm kev sib tsoo xov xwm tuaj yeem txo qhov reactivity ntawm cov hmoov, yuav tsum tau kub kub kub rau cov khoom siv ceramic.
Txheej txheem txheej txheem
Thaum lub sij hawm tsim, nws yog ib qho tseem ceeb kom tsis txhob muaj qhov sib npaug ntawm qhov sib npaug ntawm qhov tuab ntawm cov khoom thiab kom tsis txhob muaj qhov kaw ntau dhau - cell pores hauv lub cev ntsuab. Lub xub ntiag ntawm cov pores loj lossis cov laminations sab hauv tuaj yeem cuam tshuam lub zog dielectric (hluav taws xob tawg tsis kam) ntawm lub cev ceramic ua tiav.
Kev tua hluav taws
Lub sijhawm tua hluav taws yuav tsum tau tswj xyuas nruj me ntsis, siv qhov siab -cov cuab yeej tswj qhov kub thiab txias thiab cov rooj tog hauv tsev nrog cov thermal conductivity zoo heev.
Encapsulation
Kev xaiv ntawm cov ntaub ntawv encapsulation, kev tswj cov txheej txheem encapsulation, thiab kev kho deg ntawm cov khoom siv ceramic muaj qhov cuam tshuam loj heev rau lub capacitor tus yam ntxwv. Yog li ntawd, nws yog ib qho tsim nyog yuav tau xaiv cov ntaub ntawv encapsulation uas nthuav tawm cov dej noo zoo heev, tsim kom muaj kev sib raug zoo nrog ceramic nto, thiab muaj lub zog dielectric siab. Tam sim no, epoxy resin yog cov khoom siv dav tshaj plaws, txawm hais tias qee cov khoom siv phenolic resin rau encapsulation. Qee cov tuam txhab lag luam kuj siv ob -kab ruam txoj hauv kev uas muaj cov txheej txheem thawj zaug ntawm cov kua roj vanish ua raws li los ntawm encapsulation nrog phenolic resin; txoj hauv kev no muaj qee qhov zoo ntawm cov nqi txo. Hauv loj - cov kab ntau lawm, hmoov encapsulation tshuab yog nquag ua haujlwm.
Txhawm rau txhim kho qhov tawg ntawm cov khoom siv hluav taws xob ceramic, txheej txheej iav glaze feem ntau siv nyob ib puag ncig ntawm qhov cuam tshuam ntawm cov electrodes thiab dielectric nto. Cov txheej txheem no ua tau zoo txhim kho ob qho tib si qhov hluav taws xob muaj peev xwm tiv taus thiab siab - qhov kub thiab txias kev ua haujlwm ntawm ceramic capacitors siv nyob rau hauv siab -voltage circuits, xws li cov pom hauv TV teeb. Piv txwv li, daim ntawv thov ntawm cov hlau lead borosilicate iav glaze tuaj yeem ua rau lub capacitor tawg voltage los ntawm ib qho ntawm 1.4 nyob rau hauv DC hluav taws xob teb thiab los ntawm ib qho ntawm 1.3 nyob rau hauv AC hluav taws xob teb.
