Sekepe sa Mocheso oa Ceramic

Tlhaloso e Khutšoanyane:

Sekepe sa mocheso oa ceramic haholo-holo se entsoe ka lera la ho qhala mocheso le lera la conduction ea mocheso, lera la ho qhala mocheso ke tšebeliso ea mohato oa mokelikeli oa phetoho ea lik'hemik'hale ho latex slurry e sa lekanang ho qhalakanngoa, sebopeho sa poone ea ceramic e tšesaane, 'me e kopantsoe le sub-micron. phofo, 'me joale e thunngoa ka sekoti kristale cavity sebopeho mocheso dissipation lera, porosity ea micro cavity sebopeho sa mocheso dissipation lera pakeng tsa 5% le 40%, The phatsa boholo ba phofo ke pakeng tsa 90 nm le 300 nm.Sebaka sa ho kopana le mohloli oa mocheso se na le mocheso oa conductivity oa mocheso, o monyang le ho tsamaisa mohloli oa mocheso.Ka sebaka se phahameng sa sebopeho sa porous sa mocheso oa mocheso oa mocheso, matla a ho senya mocheso a ntlafatsoa ka ho sebelisa moea e le mocheso oa mocheso oa mocheso.

Sekepe sa mocheso oa ceramic ke sesebelisoa se senyang mocheso ho tloha likarolong tsa elektronike tse nang le mocheso oa sesebelisoa sa motlakase.Hajoale, letlapa le sebelisoang hangata la aluminium ceramic, aluminium nitride ceramic sheet, silicon carbide ceramic sheet.

Letlapa la ceramic la aluminium: E na le ts'ebetso e phahameng ea mocheso, conductivity ea mocheso: 24W / MK, mocheso o phahameng / khatello e phahameng ea khatello, mocheso o lekanang, ho chesa mocheso ka potlako.Ho phaella moo, e na le sebopeho se bonolo le se kopane, boholo bo bonyenyane, bokaholimo bo boreleli, matla a phahameng 'me ha ho bonolo ho senya, ho hanyetsa kutu ea acid le alkali, ho tšoarella.

Letlapa la aluminium nitride ceramic:Mmala o bosoeu bo bosoeu, bokaholimo bo boreleli, bo ka etsoa ka sebopeho kapa boholo bofe kapa bofe, bo bonolo ho bo sebelisa le ho bo kenya.Radiator ena ea ceramic e na le conductivity e phahameng haholo ea mocheso, mocheso oa mocheso ke linako tse 7-10 tsa letlapa la alumina ceramic, le ka fihla holimo ho 180W, ts'ebetso ea eona ea motlakase ea motlakase e tsitsitse haholo, dielectric kamehla le tahlehelo e bohareng e tlaase, e ka mamella likhato tse 1800 tsa Celsius le ha e ame ts'ebetso ea sehlahisoa.Ka nts'etsopele e potlakileng ea lisebelisoa tsa elektroniki, tlhokahalo ea lihlahisoa tsa elektroniki kapa tse thusang e ntse e eketseha, mme sekhahla sa ts'ebeliso ea sehlahisoa sena e le letlapa le phahameng la conductivity la aluminium nitride ceramic joalo ka matrix kapa thepa ea ho paka e ntse e eketseha le ho feta 'marakeng. .

Letlapa la silicon carbide ceramic: Ke lisebelisoa tse tala tsa tšireletso ea tikoloho, ke tsa sebopeho sa microporous, sebakeng se le seng sa yuniti e ka ba porosity e fetang 30%, e eketsa haholo sebaka sa ho senya mocheso le ho kopana le moea, ho ntlafatsa phello ea mocheso oa mocheso.Ka nako e ts'oanang, mocheso oa mocheso oa eona o monyenyane, polokelo ea eona ea mocheso e nyenyane, mocheso o ka fetisetsoa lefats'eng la ka ntle ka potlako, litšobotsi tse ka sehloohong tsa mocheso oa mocheso oa ceramic: ts'ireletso ea tikoloho, ho kenya letsoho le ho hanyetsa khatello e phahameng, mocheso o sebetsang hantle oa mocheso. , ho qoba ho ikatisa ha mathata a EMI.E ka rarolla ka katleho mathata a ho tsamaisa mocheso le ho senya mocheso indastering ea lisebelisoa tsa elektronike le lisebelisoa tsa lapeng.Ka nako e ts'oanang, e loketse ka ho khetheha bakeng sa tšebeliso ea matla a metsi a manyenyane le a mahareng.Sebaka sa moralo se ela hloko lihlahisoa tse bobebe, tse tšesaane, tse khutšoane le tse nyane, tse ka fanang ka ts'ehetso ea tekheniki le ts'ebeliso ea ntlafatso le nts'etsopele ea lihlahisoa tsa elektronike.
