Eminyakeni yamuva, ukuthuthuka okushisayo kwemikhiqizo yenjoloba sekutholile ukunakwa kakhulu. Imikhiqizo evuthayo yenjoloba eshisayo isetshenziswa kabanzi emikhakheni ye-aerospace, izindiza, ama-elekthronikhi, kanye nemishini kagesi yokudlala indima ekushiseni, ekufakweni nasekutholeni ukushaqeka. Ukuthuthukiswa kokusebenza okushisayo kubaluleke kakhulu emikhiqizweni evuthayo enjoloba. Izinto ezihlanganisiwe zenjoloba ezilungiselelwe i-filler ye-thermicr zingadlulisela ngempumelelo ukushisa, okubaluleke kakhulu ekuhlazisweni kanye nokuncishiswa kwemini ye-elekthronikhi, kanye nokwenza ngcono ukuthembeka kwabo kanye nokunwetshwa kwempilo yabo yenkonzo.

Njengamanje, izinto zenjoloba ezisetshenziswa emathangeni zidinga ukuba nezimpawu zesizukulwane esiphansi sokushisa kanye nokusebenza okuphezulu okushisayo. Ngakolunye uhlangothi, kwinqubo yeTire Vulcanization, ukusebenza kokufudumeza okushisayo kwerabha kuyathuthuka, izinga lokuvuselela liyanda, futhi ukusetshenziswa kwamandla kuncishisiwe; Ukushisa okwenziwe ngesikhathi sokushayela kunciphisa izinga lokushisa lesidumbu futhi kunciphise ukonakaliswa kokusebenza kwamathayi okubangelwa ukushisa ngokweqile. Ukuvuselelwa okushisayo kwenjoloba okuphathekayo okuthe xaxa kunqunywa ikakhulu yi-matrix yerabha kanye ne-filler ephathekayo. Ukuvuselelwa okushisayo kwezinhlayiya noma i-fibrous thermal yokuphamba ingcono kakhulu kunaleyo matrix yerabha.

Ama-fillers asetshenziswa kakhulu asetshenziswa yi-therrly angenzi-thrive izinto ezilandelayo:

1. Isigaba se-Cubic Beta Isigaba se-Nano Silicon Carbide (Sic)

Amafomu we-nano-scale we-silicon Carbide Powder athintana namaketanga okushisa, futhi kulula ukugabha ngama-polymers, athuthukisa kakhulu indlela yokushisa eshisayo njengendlela yokushisa eshisayo ye-composite ebonakalayo ngaphandle kokunciphisa impahla eyinhlanganisela yezakhiwo zemishini.

Ukuvuselelwa okushisayo kwe-silicon Carbide Epoxy Epoxy Material kuyakhuphuka ngokwanda kwenani le-carbide ye-silicon, futhi i-carbide ye-nano-silicon kunganikeza impahla eyinhlanganisela enhle kakhulu lapho inani liphansi. Amandla aguqukayo kanye namandla omthelela we-Silicon Carbide Epoxy Materials Accosite Materies anyuse kuqala bese ekwehla ngokwanda kwenani le-silicon carbide. Ukuguqulwa komhlaba kwe-silicon Carbide kungathuthukisa ngempumelelo ukuthuthuka okushisayo kanye nezindawo zemishini yezinto ezihlanganisiwe.

I-Silicon Carbide inezakhiwo ezizinzile zamakhemikhali, ukuvumelanisa kwayo okushisayo kungcono kunezinye izicubu ze-semiconductor, kanye nokuvuselelwa kwaso okushisayo kukhulu kakhulu kunalokho kwensimbi ekushiseni kwegumbi. Abaphenyi baseBeijing University of Chemical Technology bacwaninga ngokuvuselelwa okushisayo kwe-alumina kanye ne-silicon Carbide aqinisiwe irabha le-silicone. Imiphumela ikhombisa ukuthi ukuthuthuka okushisayo kwerabha le-silicone kukhuphuka njengenani le-silicon carbide lenyuka; Lapho inani le-carbiide ye-silicon liyefana, ukuqina okushisayo kwesayizi elincane le-silicon Carbide eliqinisiwe kukhulu kune-silicon carbide eqiniswe yi-silicon carbide eqiniswe irabha; Ukuvuselelwa okushisayo kwe-silicon Rubber kuqiniswe nge-silicon Carbide kungcono kunalokho kwe-alumina irabha eliqinisiwe. Lapho isilinganiso esikhulu se-Alumina / Silicon Carbide singu-8/2 kanti inani eliphelele liyizingxenye ezingama-600, ukuthuthuka okushisayo kwe-silicon Rubber kuhamba phambili.

2. I-Aluminium nitride (ALN)

I-Aluminium Nitride iyi-atomic crystal futhi ingeyakwaDayimane NITride. Kungaba khona ngokuqinile ekushiseni okuphezulu kwama-2200 ℃. Inokuvuka okuhle okushisayo kanye ne-coefficie ephansi yokunwebeka, okwenza kube yinto enhle yokushaqeka okushisayo. Ukuvuselelwa okushisayo kwe-aluminium nitride kungu-320 w · w Abaphenyi baseQingdao University of Science neTechnology bafundele ukuthuthuka okushisayo kwe-aluminium nitride aqinisiwe ama-aluminium nitride aqinisiwe ahlanganiswe ama-EPDM Rubber Composites. Imiphumela ikhombisa ukuthi: Njengoba inani le-aluminium nitride liyanda, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kuyanda; Ukuvuselelwa okushisayo kwezinto ezihlanganisiwe ngaphandle kwe-aluminium nitride kungu-0.26 w · (m ·

3. Nano alumina (Al2o3)

I-Alumina uhlobo lwe-inorganic foller olusebenzayo, olunokuqhutshwa okukhulu okushisayo, ukumelana okungapheli kwe-dielectric kanye nokugqokwa okuhle. Isetshenziswa kabanzi ngezinto ezihlanganisiwe zenjoloba.

Abaphenyi baseBeijing University of Technology Technology bahlola ukuthinta okushisayo kweNano-Alumina / Carbon Nanotube / Composites yemvelo. Imiphumela ikhombisa ukuthi ukusetshenziswa okuhlangene kweNano-Alumina neCarbon Nanotubes kunomthelela wokuvumelanisa nokwenza ngcono ukuthuthuka okushisayo kwezinto ezihlanganisiwe; Lapho inani le-carbon nanotubes lihlala lihlala likhona, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kukhulisa ngokuqondile ngokwanda kwenani le-nano-alumina; Lapho u-100 lapho usebenzisa i-nano-alumina njengomsizi ophethe kahle, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kukhuphuka ngo-120%. Lapho izingxenye ezi-5 ze-carbon nanotubes zisetshenziswa njenge-filler ephathekayo, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kukhuphuka ngo-23%. Lapho izingxenye eziyi-100 zezingxenye ze-alumina nezingxenye ezi-5 zisetshenziswa lapho kusetshenziswa i-carbon nanotubes njengomsizi ovuthayo we-thermally, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kukhuphuka ngo-155%. Ukuhlolwa kubuye kudwebe iziphetho ezimbili ezilandelayo: okokuqala, lapho inani le-carbon nanotubes lihlala likhona, njengoba inani le-nano-alumina liyakhuphuka, isakhiwo senethiwekhi ye-filler esenziwe yizinhlayiya zerofiti kancane zikhuphuka kancane kancane. Lapho izingxenye eziyi-100 zeNano-Alumina nezingxenye ezi-3 zama-nanotubes e-carbon zisetshenziswa ndawonye, ​​isizukulwane sokushisa okucindezelwe esinamandla sempahla eyinhlanganisela ingu-12 ① Okwesibili, lapho inani le-carbon nanotubes lihleliwe, njengoba inani le-nano-alumina liyanda, ubulukhuni kanye nokuqina kwezinyembezi zezinto ezihlanganisiwe ukwanda, ngenkathi amandla ashubile ekwehla.

4. I-Carbon Nanotube

I-Carbon Nanotubes inezindawo ezinhle kakhulu zomzimba, ukusebenza okushisayo kanye nokusebenza kukagesi, futhi kungama-fillers aqinisile. Izinto zabo eziqinisayo zenjoloba zithole ukunakwa okusabalele. Kwakhiwa ama-carbon nanotubes ngezendlalelo ezilindayo zamashidi we-graphite. Uhlobo olusha lwe-graphite impahla enesakhiwo se-cylindrical esinobubanzi bamashumi ama-nanometers (10-30NM, 30-60NM, 60-100nm). Ukuvuselelwa okushisayo kwe-carbon nanotubes kungu-3000 w · w · (m · k) -1, okuphi izikhathi ezi-5 zokuvuselelwa kwethusi. I-Carbon Nanotubes ingathuthukisa kakhulu ukuthuthuka okushisayo, ukuqina kukagesi kanye nezakhiwo ezibonakalayo zenjoloba, futhi ukuqiniswa kwazo nokuqina kwazo kungcono kunama-carbon amnyama, i-carbon fiber kanye ne-fiber yengilazi. Abaphenyi baseQingdao University of Science neTechnology baqhuba ucwaningo ngokuvuselelwa okushisayo kwe-carbon nanotubes / i-EPDM composite izinto. Imiphumela ikhombisa ukuthi: I-Carbon Nanotubes ingathuthukisa ukusebenza okushisayo kanye nezinto ezibonakalayo zezinto ezihlanganisiwe; Njengoba inani le-carbon nanotubes likhuphuka, ukuthuthuka okushisayo kwezinto ezihlanganisiwe kukhuphuka, namandla ashukumisayo kanye nokugcwala lapho kukhula ekuqaleni bese kuncipha, ukucindezelwa okuthe xaxa kuyanda; Lapho inani le-carbon nanotubes lincane, iningi le-carbon nanotubes kulula ukwakha amaketanga okwenza ukushisa kwama-carbon nanotubes, futhi ahlanganiswe kangcono ne-matrix yerabha.
