Kwiminyaka yakutshanje, ukuqhubela kwe-thermal yeemveliso zerabha ifumene ingqalelo ebanzi. Iimveliso zerabha zerabha esetyenziswa ngokubanzi zisetyenziswa ngokubanzi kumacandelo e-aerospace, inqwelo moya, i-elektroniki, kunye nezixhobo zombane zokudlala indima ekuqulunqweni komsebenzi wobushushu, i-insulser kunye neyothusa. Ukuphuculwa kokuphuculwa kwe-thermal kubaluleke kakhulu kwiimveliso zerabha. Izinto ezihlanganisiweyo zerabha ezilungiselelwe ngumfihleli obenziweyo zinokutshintshela ngokufanelekileyo ubushushu kwaye bubaluleke kakhulu kwiimveliso ze-elektroniki, kunye nokuphuculwa kwentembeko yobomi babo.

Okwangoku, izinto zerabha ezisetyenziswa kumatayara kufuneka zibe neempawu zokuveliswa kobushushu obuphantsi kunye nokuphumelela okuphezulu. Kwelinye icala, kwinkqubo yokuziqhelanisa i-tyhunga, ukutshintshwa kobushushu kwerabha kuphuculwe, ireyithi yobuqhetseba iyanda, kwaye ukusetyenziswa kwamandla kuncitshisiwe; Ubushushu obuveliswe ngexesha lokuqhuba kunciphisa ubushushu besidumbu kwaye kunciphise ukonakala kwendlela yokusebenza kwengqondo ebangelwe bubushushu obukhulu. Ukuqhubela kwe-thermal yerabha ngokuthembekileyo kumiselwa ikakhulu yirabha yerabha kunye ne-filler emnyama. Ukuqhubela phambili kwe-thermal nokuba amasuntswana okanye i-fibm ye-fibble ye-filter ilunge ngakumbi kune-matrix yerabha.

Ezona zixhaphakileyo zisetyenziswa ngokuthe gca iifilimu zezi zinto zilandelayo:

1. I-Cubic Beta yeSigaba se-Beta Silicon Carbide (i-SIC)

I-Nano-Back Silicon Parbide Powder Iifom zoKhuphiswano lobushushu, kwaye kulula ukubhala i-polymers, ekwakhetha i-skein yokuphucula i-Skelemes, ephucula kakhulu indlela yokuqhubela phambili kwempahla yokudibanisa izinto ezihlanganisiweyo.

Ukuqhubela phambili kwe-thermal ye-Clicon Carbide Epoxy Epoxy Epoxy ye-Epoxy ye-Epoxy ye-Silicon Carbide, kwaye i-Nano-Carbide inokunika izinto ezihlanganisiweyo xa imali iphantsi. Amandla aguqukayo kunye namandla empembelelo ye-Silicon Carbide Eposupy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy Espoxy I-Epossox eKonyusa kuqala emva koko incitshiswe ngokunyuka kwexabiso le-silicon carbide. Ukulungiswa okungaphezulu kwe-selicon carbide kunokuphucula ngokufanelekileyo ukuqhutywa kwe-shirmal kunye neempawu zoomatshini zezinto ezihlanganisiweyo.

I-Silicon Carbide inezindlu ezizinzileyo zeekhemikhali, ukuSebenza kwayo ngeMpumelelo kungcono kunezinye iifilimu ze-semiconductor, kwaye ukuqhubela phambili kwe-sumicom mkhulu nangaphezulu kuneso sinyithi kubushushu begumbi. Abaphandi kwiDeijing kwiTekhnoloji yeTekhnoloji yeekhemikhali ezaqhutywa uphando malunga nokuphuculwa kwe-aluminii kunye ne-silicon carbide yomeleza irabha ye-silicone. Iziphumo zibonisa ukuba ukuqhubela kwengqondo yerabha yerabha yerabha njengenani le-silicon carbide yonyuswa; Xa inani lexabiso le-calbide le-silicon liyafana, ukuqhubela kwe-thermal ye-paricle ye-carbide ye-silicon ye-silicone irabha ingaphezulu kweyona nto iphambili kwi-carbicle ye-silicone ye-silicone yerabha; Ukuqhubela kwe-sermal yerabha eqiniswe nge-silicon carbide kungcono kunelo ka-Alumina yomeleze irabha yeSilicon. Xa umyinge omkhulu we-Aluminii / Slicon Carbide yi-8/2 kwaye inani lilonke ngamacandelo angama-600, ukuqhubela kwengqondo yerabha yeSilicon irabha yeyona ilungileyo.

2. I-aluminium nitride (Aln)

I-Aluminium Nitride yikristali yeatomic kwaye yeyokidayimani witride. Inokubakho ngokusesikweni kubushushu obuphezulu abangama-2200 ℃. Inengxaki yokuhamba kwe-hormal elungileyo kunye nokwandiswa okuphantsi kwe-thermal ukusebenza, kuyenza ibe yinto entle yokothuswa. Ukuqhubela kwe-Aluminium ye-Aluminium yi-320 Wi-M · m (nge-1, esondeleyo ekuqhubeni i-thermas ye-boron oxide ne-silicon carbide, kwaye ingaphezulu kwamaxesha ama-Aluminii. Abaphandi kwi-Qingdao Universivesithi yesayensi kunye netekhnoloji baye bafunda ukuqhubela phambili kwe-aluminium nitride eyomeleza i-EPDM i-EPDM iqhekeza izihlunu zerabha. Iziphumo zibonisa ukuba: Njengexabiso le-aluminium yonyuso, ukuqhubela kwenkululeko yokunyuka kokuhlulwa kwezinto; Ukuqhubela phambili kwe-shirmal yezinto ezihlanganisiweyo ngaphandle kwe-aluminium nitride yi-0.26 Witride -1, xa inani le-Aluminium yonyuswa ukuya kuma-80 ama-Alumn, ukuqhubela phambili kwe-MATE) -1, ukunyuka kwama-70%.

3. I-Nano Alumina (Al23)

I-Alumna luhlobo lwe-Inorganic ye-Inorganic ye-Inorganic, enobunkunkqele obukhulu, i-Diectoric rhoqo kwaye inxibe kakuhle. Isetyenziswe ngokubanzi kwizinto ezihlanganisiweyo zerabha.

Abaphandi abavela kwiDeijing Beijity kwitekhnoloji yeekhemikhali bavavanya ukuqhubela phambili kwe-nano-alumina / i-carbon natbube / irabha yendalo. Iziphumo zibonisa ukuba ukusetyenziswa okuhlanganisiweyo kwe-Nano-Aluminina kunye ne-carbon nanon kunesiphumo esilinganayo ekuphuculeni ukuqhubela phambili kwempahla yobukrwada; Xa inani lenani leekhabhoni lihlala lihleli, ukuqhubela kwe-shirmal yezinto ezihlanganisiweyo kukonyusa umgca kwinani le-NANo-Aluminina; Xa i-100 xa isebenzisa i-nano-alumina njenge-filler emnyama, ukuqhubela phambili kwenkululeko yokunyuswa kwe-120%. Xa iinxalenye ezi-5 zeekhabhoni zekhabhoni zisetyenziswa njenge-filler emnyama, ukuqhubela kwe-shirmal yezinto ezihlanganisiweyo nge-23%. Xa iinxalenye ezili-100 ze-Aluminina kunye neenxalenye ezi-5 zisetyenziswa xa i-carbon nanobs isetyenziswa njenge-filler ehleliyo, ukuqhubela phambili kwe-shirmal yezinto ezinokunyuka nge-155%. Uvavanyo lukwazisa ezi zigqibo zimbini zilandelayo: Okokuqala, xa inani leekhabhoni lihlala lihleli, njengoko inani le-Nano-Alumina lisonyuka ngokunyuka kwerabha ngokuthe ngcembe, kwaye into elahlekileyo iyanda. Xa iinxalenye ezili-100 zeNano-Aluminina kunye neenxalenye ezi-3 zekharbon nanobs zisetyenziswa ndawonye, ​​ukuzala kobushushu obunamandla kwizinto ezihlanganisiweyo ziipropathi eziguqukayo. Okwesibini, xa inani le-carbon nanobs lilungisiwe, njengesixa se-Nano-Aloumina sonyuka, ubunzima kunye namandla obuzingalisayo bezinto ezihlanganisiweyo, ngelixa amandla e-surile kunye ne-Elongile kwi-Dreat.

4. I-carbon nautube

I-carbon natoutubs inepropathi ebalaseleyo yokwenyama, ukuqhubela phambili kwengqondo kunye nokuqhutywa kombane, kwaye zikwamele ukuqinisa iifilimu. Izinto zabo zokulinganisa irabha zifumene ingqalelo ebanzi. I-carbon nanobi yenziwa ngamacala e-curling amaphepha amaphepha. Luhlobo olutsha lwezinto zegrafu ezinesakhiwo se-cylindrical esinemithambo yamashumi eNanometers (10-30nm, 30-60nm, i-60-100nm). Ukuqhubela phambili kwe-carbn nanowes yi-3000 W · m (i-5, enamaxesha ama-5 eyokuphambuka kobhedu. I-carbon nanobi ingayiphucula kakhulu ukwenziwa kwe-shirmal, ukwenziwa kombane kunye neepropathi zerabha, kwaye ukuqiniswa kwabo kunye nokuqhuma kwabo kungcono kune-carbon emnyama, i-carbon fiber kunye nefayibha ye-carbon emnyama. Abaphandi kwi-Qingdao Universivesithi yeSayensi kunye neTekhnoloji eqhube inxaxheba kuphando ngembonakalo ye-carbn nanobs / e-EPDM. Iziphumo zibonisa ukuba: I-carbon nanobi natwes inokuphucula ukwenziwa kwe-shirmal kunye neempawu zomzimba zezinto ezihlanganisiweyo; Njengoko inani leekharbon natosubs, ukuqhubela kwengqondo kwezinto ezihlanganisiweyo kuyanda, kwaye amandla obuzini kunye ne-elongile kunye nokwehla, ukomelela kwamandla kunye nokukrazula; Xa inani lexabiso lekhabhoni incinci, i-carbon ye-carbon ye-carbon ye-National Nanon ilula ukwenza amakhonkco okwenza amakhonkco okwenza amakhonkco e-carbon ye-carbon ye-nameter natutubs, kwaye zidibene ne-mattrix yerabha.
