Hauv tsab xov xwm no, peb yuav tshawb txog lub luag haujlwm ntawm cov nplaum hauv kev tsim cov khoom siv hluav taws xob ceramic thiab lawv qhov tseem ceeb hauv kev ua tiav cov khoom zoo, txhim khu kev qha Circuit Court boards.
Nyob rau hauv xyoo tas los no, ceramic circuit boards tau nrov heev vim lawv cov thermal thiab hluav taws xob zoo heev. Lawv tau siv dav hauv ntau yam kev lag luam, suav nrog tsheb, aerospace thiab kev sib txuas lus. Cov txheej txheem ntawm cov khoom siv hluav taws xob ceramic muaj ob peb kauj ruam yooj yim, ib qho ntawm kev siv cov nplaum nplaum.
Yog li, dab tsi yog lub luag haujlwm ntawm cov nplaum ua si hauv kev tsim cov khoom siv hluav taws xob ceramic?
Txhawm rau kom nkag siab qhov no, cia peb ua ntej txhais tias lub binder yog dab tsi. Hauv kev tsim cov khoom siv hluav taws xob ceramic, cov ntawv khi yog cov khoom siv ntxiv rau cov hmoov ceramic sib tov los txhim kho nws cov tuav thiab ua haujlwm. Nws ua raws li cov nplaum ib ntus uas pab khi cov khoom ceramic ua ke thaum lub sij hawm molding thiab cov kauj ruam tom ntej.
Lub luag haujlwm tseem ceeb ntawm cov nplaum hauv cov khoom siv hluav taws xob ceramic yog muab lub zog ntsuab rau lub cev ceramic.Lub zog ntsuab hais txog lub peev xwm ntawm cov khoom siv hluav taws xob uas tsis muaj hluav taws xob los tiv thaiv kev tuav, shaping, thiab kev thauj mus los yam tsis muaj kev tawg lossis tawg. Qhov no yog qhov tseem ceeb vim tias cov ntaub ntawv ceramic yog nkig thiab nkig, ua rau lawv muaj kev cuam tshuam rau kev puas tsuaj thaum lub sijhawm tsim khoom. Los ntawm kev ntxiv cov ntawv khi, cov qauv ntawm cov hmoov ceramic hmoov sib tov ua kom ruaj khov, ua kom yooj yim rau kev tswj thiab cov duab tsis muaj qhov tseem ceeb deformation.
Ntxiv nrog rau lub zog ntsuab, cov nplaum ua lub luag haujlwm tseem ceeb hauv kev ua tiav qhov tseeb qhov yuav tsum tau muaj rau cov laug cam ceramic.Lub binder tuav cov khoom siv ceramic ua ke thaum lub sij hawm molding txheej txheem, tiv thaiv ntau shrinkage los yog deformation. Qhov no yog qhov tseem ceeb tshwj xeeb tshaj yog thaum tsim cov khoom siv hluav taws xob sib txuas uas xav tau cov qauv meej thiab sib txawv. Yog tias tsis muaj kev sib khi, cov khoom siv ceramic tuaj yeem txav los yog hloov pauv thaum lub sijhawm molding, ua rau cov qauv distortion thiab cuam tshuam kev ua haujlwm.
Lwm qhov tseem ceeb ntawm cov nplaum hauv cov khoom siv hluav taws xob ceramic yog lawv lub peev xwm los tswj cov viscosity ntawm ceramic slurries.Slurry yog ib qho sib xyaw ntawm cov hmoov ceramic, binders thiab lwm yam additives raug tshem tawm hauv cov kua nruab nrab. Lub viscosity ntawm slurry txiav txim siab nws ntws thiab yooj yim ntawm deposition mus rau lub substrate. Los ntawm kev kho cov ntsiab lus binder, manufacturers tuaj yeem hloov qhov viscosity ntawm slurry los xyuas kom meej tias Circuit Court boards yog coated los yog luam tawm tusyees.
Tsis tas li ntawd, cov binder pab tshem tawm cov khoom siv organic thaum lub sijhawm tua hluav taws.Ceramic circuit boards dhau los ntawm cov txheej txheem hluav taws kub kub uas cov nplaum hlawv thiab tawg. Kev kub hnyiab ntawm cov binder tshem tawm cov organic Cheebtsam, tawm hauv cov qauv ceramic ntshiab. Tshem tawm cov nplaum yog qhov tseem ceeb vim tias nws tiv thaiv kev tsim cov pa roj carbon monoxide, uas tuaj yeem cuam tshuam rau hluav taws xob thiab thermal zog ntawm lub rooj tsavxwm.
Nws yog ib qho tseem ceeb uas yuav tsum nco ntsoov tias cov nplaum uas siv rau hauv kev tsim cov khoom siv hluav taws xob ceramic yuav tsum tau ua tib zoo xaiv kom ntseeg tau tias muaj kev sib raug zoo nrog cov khoom xav tau ntawm cov khoom kawg.Qhov zoo tshaj plaws, cov nplaum yuav tsum muaj cov khoom sib txuas zoo, qis shrinkage thiab negligible residue tom qab decomposition. Kev xaiv cov nplaum tsim nyog nyob ntawm seb yam xws li hom khoom siv ceramic, qhov xav tau kev ua haujlwm thiab cov txheej txheem tsim khoom siv.
Hauv cov ntsiab lus,adhesives ua lub luag haujlwm tseem ceeb hauv kev tsim cov khoom siv hluav taws xob ceramic. Lawv muab lub zog ntsuab, tswj qhov tseeb qhov tseeb, tswj cov slurry viscosity thiab pab tshem tawm cov khoom siv organic. Kev nkag siab thiab ua kom zoo dua lub luag haujlwm ntawm cov nplaum yog qhov tseem ceeb kom tau txais cov khoom siv hluav taws xob zoo tshaj plaws nrog cov thermal thiab hluav taws xob zoo. Raws li qhov kev thov rau ceramic circuit boards txuas ntxiv mus, cov tuam ntxhab yuav tsum tau tshawb nrhiav thiab tsim cov thev naus laus zis tshiab los ua kom tau raws li kev xav tau ntawm kev lag luam.
