I-graphite enwetshiwe, eyaziwa nangokuthi i-vermicular graphite, iyinhlanganisela yecrystalline esebenzisa izindlela ezingokoqobo noma zamakhemikhali ukuze ihlanganise izinto ezisabelayo ezingezona ikhabhoni zibe izinto ze-nanocarbon ezihlanganisiwe ze-graphite ezilinganiselwe ngokwemvelo futhi ihlanganiswe nezindiza zenethiwekhi ye-carbon hexagonal ngenkathi igcina uhlaka lwe-Graphite layer. Ayigcini nje ngokugcina izici ezinhle kakhulu zomzimba namakhemikhali e-graphite, njengokumelana nokushisa okuphezulu, ukumelana nokugqwala, i-neutron flux, i-X-ray kanye ne-gamma-ray ye-irradiation yesikhathi eside. Iphinde ibe nezakhiwo ezinhle kakhulu zomzimba namakhemikhali, njenge-coefficient ephansi yokungqubuzana, ukuzigcoba okuhle, ukuhanjiswa kukagesi nokushisayo, kanye ne-anisotropy. Ngaphezu kwalokho, ngenxa yokuxhumana phakathi kwezinto ezixubene nongqimba lwe-graphite, i-graphite enwetshiwe ibonisa izici ezintsha i-graphite ehlanzekile nezinto ezihlanganisiwe ezingenazo, futhi inqoba ukuqina nomthelela wokuphikiswa kwegraphite yemvelo. Abahleli abalandelayo be-Furuite graphite babelana ngokwethulwa kwezindlela zokuhlanganisa izimboni kanye nokusetshenziswa kwegraphite enwetshiwe:
1. Izindlela zokwenziwa ezivame ukusetshenziswa embonini
①I-Chemical oxidation
Izinzuzo: I-Chemical oxidation iyindlela esetshenziswa kakhulu futhi esungulwe kahle embonini. Ngakho-ke, inezinzuzo ezisobala, ubuchwepheshe obuvuthiwe kanye nezindleko eziphansi.
Ububi: I-ejenti ehlanganisayo ngokuvamile i-concentrated sulfuric acid, edla inani elikhulu le-asidi. Kukhona ukungcoliswa kwegesi okuyingozi kwe-Sox enqubweni yokukhiqiza, futhi izinsalela emkhiqizweni ziphinde zigqwalise imishini yokuhlanganisa.
②I-Electrochemical oxidation
Njenge-oxidation yamakhemikhali, ingenye yezindlela ezivamile zokwenziwa kwezimboni ze-graphite eyandisiwe.
Izinzuzo: Asikho isidingo sokwengeza ama-oxidants aqinile, njengama-acids aqinile, futhi ukusabela kungalawulwa ngokulungisa amapharamitha afana namanje kanye ne-voltage. Imishini yokuhlanganisa ilula, inani le-synthesis likhulu, i-electrolyte ayingcolisiwe, futhi ingasetshenziswa kabusha.
Ukungalungi: Ukuzinza komkhiqizo ohlanganisiwe kumpofu kunezinye izindlela, ezidinga imishini ephezulu, futhi kunezici eziningi ezithinta ikhwalithi yomkhiqizo. Ngezinye izikhathi, umthamo owandisiwe womkhiqizo uyancipha kakhulu ngenxa yokwanda kwezinga lokushisa elizungezile. Ngaphezu kwalokho, kukhona ukusabela okusemaceleni emisinga ephezulu ezixazululweni ezinamanzi, ngakho-ke kunzima ukuthola ama-compounds oda lokuqala.
2. Amabhizinisi amakhulu okukhiqiza namandla okukhiqiza
Ukukhiqizwa kwemikhiqizo ye-graphite eyandisiwe ezweni lami kukhule kusukela esigabeni sokuqala kuya kubakhiqizi abangaphezu kwe-100, ngokukhishwa konyaka okungamathani angama-30,000, futhi ukugxilwa kwemakethe kuphansi. Futhi, abakhiqizi abaningi ngokuyinhloko bangama-seal fillers asezingeni eliphansi, angavamile ukusetshenziswa ezimpawu zezimoto kanye nezibani zezindiza zenuzi. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe basekhaya, ingxenye yemikhiqizo ephezulu izokhula kancane kancane.
3. Isidingo semakethe kanye nesibikezelo sezinto zokuvala
Njengamanje, i-graphite eyandisiwe isetshenziswa kakhulu njengezinto zokuvala zezimoto, njengama-cylinder gaskets, ama-port gaskets, i-exhaust port, njll. Izinto zokuvala ze-graphite ezinwetshiwe ezweni lami zisetshenziswa kakhulu njengezifaki zokuvala. Njengamanje, i-graphite eyandisiwe enokuqukethwe kwekhabhoni ephansi iye yathuthukiswa, enganciphisa kakhulu izindleko zokukhiqiza i-graphite eyandisiwe, ngaleyo ndlela ithathe indawo ye-asbestos ngesilinganiso esikhulu futhi ikhule isidingo. Ngakolunye uhlangothi, uma ipulasitiki, irabha kanye nezinto zokuvala zensimbi zingashintshwa kancane, isidingo sasekhaya sonyaka sezinto zokuvala ze-graphite ezinwebekayo sizoba sikhulu.
Embonini yezimoto, i-gasket yekhanda le-cylinder head, ukungenisa komoya kanye ne-exhaust port gasket idinga cishe u-2~10kg we-graphite enwetshiwe, futhi zonke izimoto ezingu-10,000 zidinga amathani angu-20~100 e-graphite enwetshiwe. Imboni yezimoto yaseChina isingene enkathini yokuthuthuka ngokushesha. Ngakho-ke, isidingo sonyaka sezwe lami sezinto ezinwetshiwe zokuvala i-graphite siseyinhloso enkulu.
