Mu myaka yashize, ubushyuhe bwumuriro wibicuruzwa bya rubber byitabweho cyane.Ibikoresho bya reberi bitwara ubushyuhe bikoreshwa cyane mubijyanye n’ikirere, indege, ibikoresho bya elegitoroniki, n’ibikoresho by’amashanyarazi kugira uruhare mu gutwara ubushyuhe, kubika no kwinjiza ibintu.Gutezimbere ubushyuhe bwumuriro ningirakamaro cyane kubicuruzwa bya reberi yubushyuhe.Ibikoresho bya reberi byateguwe nubushakashatsi bwuzuza ubushyuhe bushobora kwimura neza ubushyuhe, bufite akamaro kanini mugukwirakwiza no kugabanya ibicuruzwa bya elegitoroniki, ndetse no kurushaho kwizerwa no kwagura ubuzima bwabo.

Kugeza ubu, ibikoresho bya reberi bikoreshwa mu mapine bigomba kugira ibimenyetso biranga ubushyuhe buke hamwe n’ubushyuhe bwinshi.Ku ruhande rumwe, mugikorwa cyo guhanagura amapine, imikorere yo kohereza ubushyuhe bwa reberi iratera imbere, igipimo cy’ibirunga cyiyongera, kandi ingufu zikagabanuka;Ubushyuhe butangwa mugihe cyo gutwara bugabanya ubushyuhe bwintumbi kandi bugabanya imikorere yipine iterwa nubushyuhe bukabije.Amashanyarazi yubushyuhe bwa reberi yubushyuhe bugenwa ahanini na materique ya reberi hamwe nuwuzuza ubushyuhe.Amashanyarazi yubushyuhe yaba ibice cyangwa fibrous yumuriro wuzuza ni byiza cyane kuruta materi ya rubber.

Byakunze gukoreshwa cyane byuzuye byuzuza ibikoresho ni ibikoresho bikurikira:

1. Cubic Beta icyiciro nano silicon karbide (SiC)

Ifu ya Nano-nini ya silicon karbide ifata iminyururu itwara ubushyuhe, kandi byoroshye gushinga amashami hamwe na polymers, ikora skeleton ya Si-O-Si yumuyoboro wogukwirakwiza nkinzira nyamukuru itwara ubushyuhe, iteza imbere cyane ubushyuhe bwumuriro wibikoresho bitarinze kugabanya ibikoresho byinshi Ibikoresho bya mashini.

Amashanyarazi yumuriro wa silicon karbide epoxy yibikoresho byiyongera hamwe no kwiyongera kwa karbide ya silicon, na karbide ya nano-silicon irashobora guha ibikoresho byose hamwe nubushyuhe bwiza bwumuriro mugihe amafaranga ari make.Imbaraga zingirakamaro nimbaraga zingirakamaro za silicon karbide epoxy yibikoresho byiyongera mbere hanyuma bigabanuka hamwe no kwiyongera kwa karbide ya silicon.Guhindura isura ya karubide ya silicon irashobora kunoza neza ubushyuhe bwumuriro hamwe nubukanishi bwibikoresho.

Carbide ya Silicon ifite imiti ihamye, itwara ubushyuhe bwayo iruta iyindi yuzuza semiconductor, kandi nubushyuhe bwumuriro burenze ubw'icyuma mubushyuhe bwicyumba.Abashakashatsi bo muri kaminuza ya Beijing y’ubuhanga mu bya shimi bakoze ubushakashatsi ku bijyanye n’ubushyuhe bw’umuriro wa alumina na karubide ya silicon ikomeza reberi ya silicone.Ibisubizo byerekana ko ubushyuhe bwumuriro wa silicone reberi yiyongera uko karbide ya silicon yiyongera;iyo ingano ya karibide ya silicon ari imwe, ubushyuhe bwumuriro bwingingo ntoya ya silicon karbide ya rebero ya silicone ya reberi iruta iy'ubunini bunini bwa silicon karbide ishimangira silicone;Ubushyuhe bwumuriro wa silicon reberi ishimangirwa na karubide ya silicon iruta iya alumina ishimangira silicon reberi.Iyo igipimo rusange cya alumina / silicon karbide ari 8/2 naho igiteranyo ni ibice 600, ubushyuhe bwumuriro wa silicon reberi nibyiza.

2. Aluminium Nitride (ALN)

Aluminium nitride ni kirisiti ya atome kandi ni nitride ya diyama.Irashobora kubaho neza ku bushyuhe bwo hejuru bwa 2200 ℃.Ifite ubushyuhe bwiza bwumuriro hamwe nubushobozi buke bwo kwagura ubushyuhe, bigatuma iba ibikoresho byiza byubushyuhe.Ubushyuhe bwumuriro wa nitride ya aluminium ni 320 W · (m · K) -1, yegereye ubushyuhe bwumuriro wa boride oxyde ya boron na karubide ya silicon, kandi iruta inshuro 5 kurenza alumina.Abashakashatsi bo muri kaminuza y’ubumenyi n’ikoranabuhanga ya Qingdao bakoze ubushakashatsi ku mashanyarazi ya nitride ya aluminium yongerewe imbaraga za EPDM reberi.Ibisubizo byerekana ko: uko ingano ya nitride ya aluminiyumu yiyongera, ubushyuhe bwumuriro wibikoresho byiyongera;ubushyuhe bwumuriro wibikoresho bitarimo nitride ya aluminium ni 0.26 W · (m · K) -1, iyo ingano ya nitride ya aluminiyumu yiyongereye kugera ku bice 80, ubushyuhe bwumuriro bwibikoresho bigera kuri 0.442 W · (m · K) -1, kwiyongera kwa 70%.

3. Nano alumina (Al2O3)

Alumina ni ubwoko bwimikorere myinshi ya organorganic yuzuza, ifite ubushyuhe bunini bwumuriro, dielectric ihoraho kandi irwanya kwambara neza.Ikoreshwa cyane mubikoresho bya reberi.

Abashakashatsi bo muri kaminuza ya Beijing y’ikoranabuhanga ry’ubushakashatsi bapimye ubushyuhe bw’umuriro wa nano-alumina / carbone nanotube / reberi isanzwe.Ibisubizo byerekana ko gukoresha hamwe nano-alumina na karubone nanotubes bigira ingaruka zingirakamaro mugutezimbere ubushyuhe bwumuriro wibikoresho;iyo ingano ya carbone nanotubes ihoraho, ubushyuhe bwumuriro bwibikoresho bigize ibintu byiyongera kumurongo hamwe no kwiyongera kwa nano-alumina;iyo 100 Iyo ukoresheje nano-alumina nkuzuza ubushyuhe bwumuriro, ubushyuhe bwumuriro bwibikoresho byiyongera byiyongera 120%.Iyo ibice 5 bya karubone nanotubes bikoreshejwe nkuzuza ubushyuhe bwumuriro, ubushyuhe bwumuriro wibikoresho byiyongera byiyongera 23%.Iyo ibice 100 bya alumina nibice 5 bikoreshejwe Iyo carbone nanotubes ikoreshwa nkuzuza ubushyuhe bwumuriro, ubushyuhe bwumuriro bwibikoresho byiyongera byiyongera 155%.Ubushakashatsi nabwo bukuramo imyanzuro ibiri ikurikira: Icya mbere, iyo ingano ya karubone ya nanone ya karubone ihoraho, uko ingano ya nano-alumina yiyongera, imiterere y'urusobekerane rwuzuzanya rwakozwe nuduce duto duto twinshi muri reberi yiyongera buhoro buhoro, hamwe nigihombo cya ibikoresho byinshi byiyongera buhoro buhoro.Iyo ibice 100 bya nano-alumina hamwe nibice 3 bya karubone ya nanotube ikoreshwa hamwe, imbaraga zo guhunika ubushyuhe bwo kubyara ibintu bigize ibintu byose ni 12 only, kandi ibikoresho bya mehaniki ni byiza cyane;icya kabiri, iyo ingano ya karubone nanotubes ikosowe, uko ingano ya nano-alumina yiyongera, Ubukomezi n amarira imbaraga yibikoresho byiyongera, mugihe imbaraga zingana no kurambura kuruhuka bigabanuka.

4. Carbon Nanotube

Carbone nanotubes ifite ibintu byiza byumubiri, ubushyuhe bwumuriro nu mashanyarazi, kandi nibyiza gushimangira ibyuzuzo.Ibikoresho byabo bishimangira reberi yibikoresho byitabiriwe cyane.Carbone nanotubes ikorwa no kugorora ibice byimpapuro.Nubwoko bushya bwibikoresho bya grafite bifite imiterere ya silindrike ifite diameter ya nanometero icumi (10-30nm, 30-60nm, 60-100nm).Amashanyarazi ya carbone nanotubes ni 3000 W · (m · K) -1, yikubye inshuro 5 ubushyuhe bwumuringa.Carbone nanotubes irashobora guteza imbere cyane ubushyuhe bwumuriro, amashanyarazi nu miterere yumubiri wa reberi, kandi imbaraga zayo hamwe nubushyuhe bwumuriro nibyiza kuruta kuzuza gakondo nka karubone yumukara, fibre fibre na fibre.Abashakashatsi bo muri kaminuza y’ubumenyi n’ikoranabuhanga ya Qingdao bakoze ubushakashatsi ku mashanyarazi y’umuriro wa karubone nanotube / ibikoresho bya EPDM.Ibisubizo byerekana ko: karubone nanotubes irashobora kunoza ubushyuhe bwumuriro nibintu bifatika byibikoresho;uko ubwinshi bwa karubone nanotube yiyongera, ubushyuhe bwumuriro wibikoresho byiyongera, kandi imbaraga zingana no kuramba mugihe cyo kuruhuka banza kwiyongera hanyuma bikagabanuka, Guhangayikishwa nimbaraga no kurira byiyongera;iyo ingano ya carbone nanotubes ari ntoya, nini ya diameter nini ya karubone nanotubes byoroshye gukora iminyururu itwara ubushyuhe kuruta diyimetero ntoya ya carbone nanotubes, kandi bihujwe neza na materique ya reberi.
