I-graphite enwetshiwe, eyaziwa nangokuthi i-vermicular graphite, iyinhlanganisela yekristalu esebenzisa izindlela zomzimba noma zamakhemikhali ukuhlanganisa ama-reactants angewona ama-carbon abe yizinto zemvelo ezihlanganisiwe ze-graphitic nanocarbon futhi ihlanganiswe nezinhlelo zenethiwekhi ye-carbon hexagonal ngenkathi igcina isakhiwo se-Graphite. Ayigcini nje ngokugcina izakhiwo ezinhle kakhulu zomzimba nezamakhemikhali ze-graphite, njengokumelana nokushisa okuphezulu, ukumelana nokugqwala, i-neutron flux, i-X-ray kanye ne-gamma-ray isikhathi eside. Iphinde ibe nezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali, njenge-coefficient ephansi yokungqubuzana, ukuzigcoba okuhle, ukuqhuba kukagesi nokushisa, kanye ne-anisotropy. Ngaphezu kwalokho, ngenxa yokusebenzisana phakathi kwezinto ezihlanganisiwe kanye nesendlalelo se-graphite, i-graphite enwetshiwe ibonisa izakhiwo ezintsha i-graphite ehlanzekile nezinto ezihlanganisiwe ezingenazo, futhi inqoba ubuthakathaka kanye nokumelana nomthelela we-graphite yemvelo. Abahleli be-graphite abalandelayo be-Furuite babelana ngesingeniso sezindlela zokwenziwa kwezimboni kanye nokusetshenziswa kwe-graphite enwetshiwe:
1. Izindlela zokwenziwa ezivame ukusetshenziswa embonini
①Ukushiswa kwamakhemikhali
Izinzuzo: Ukushiswa kwamakhemikhali kuyindlela esetshenziswa kabanzi futhi esungulwe kahle embonini. Ngakho-ke, inezinzuzo ezisobala, ubuchwepheshe obuvuthiwe kanye nezindleko eziphansi.
Ububi: I-ejenti yokuhlanganisa imvamisa i-sulfuric acid egxilile, edla inani elikhulu le-asidi. Kukhona ukungcola kwegesi okuyingozi kwe-Sox enqubweni yokukhiqiza, futhi izinsalela kumkhiqizo nazo zilimaza imishini yokwenziwa.
②Ukushiswa kwe-electrochemical
Njenge-oxidation yamakhemikhali, ingenye yezindlela ezivamile zokwenziwa kwezimboni ze-graphite enwetshiwe.
Izinzuzo: Asikho isidingo sokwengeza ama-oxidant aqinile, njengama-acid aqinile, futhi ukusabela kungalawulwa ngokulungisa amapharamitha afana nogesi kanye ne-voltage. Imishini yokwenza izinto ilula, inani lokwenza izinto likhulu, i-electrolyte ayingcolisiwe, futhi ingasetshenziswa kabusha.
Okubi: Ukuzinza komkhiqizo owenziwe kuphansi kunezinye izindlela, ezidinga imishini ephezulu, futhi kunezici eziningi ezithinta ikhwalithi yomkhiqizo. Ngezinye izikhathi, ivolumu enwetshiwe yomkhiqizo incipha kakhulu ngenxa yokwanda kwezinga lokushisa elizungezile. Ngaphezu kwalokho, kunezimpendulo ezingemuhle kumaza aphezulu ezixazululweni zamanzi, ngakho-ke kunzima ukuthola ama-compounds okuqala.
2. Amabhizinisi amakhulu okukhiqiza kanye namandla okukhiqiza
Ukukhiqizwa kwemikhiqizo ye-graphite eyandisiwe ezweni lakithi kukhule kusukela esigabeni sokuqala kwaya kubakhiqizi abangaphezu kwe-100, okukhiqizwa minyaka yonke okungaba amathani angu-30,000, futhi ukuhlushwa kwemakethe kuphansi. Futhi, abakhiqizi abaningi bangabagcwalisi be-seal abasezingeni eliphansi, abavame ukusetshenziswa ezimpahleni zezimoto nasezibanini zezindiza zenuzi. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe basekhaya, isilinganiso semikhiqizo esezingeni eliphezulu sizokhula kancane kancane.
3. Isidingo semakethe kanye nokubikezela kwezinto zokuvala
Njengamanje, i-graphite enwetshiwe isetshenziswa kakhulu njengezinto zokuvala izimoto, njenge-gaskets zesilinda, ama-gaskets okungenisa kanye nokukhipha umoya, njll. Izinto zokuvala i-graphite enwetshiwe ezweni lakithi zisetshenziswa kakhulu njengezinto zokugcwalisa i-sealing. Njengamanje, i-graphite enwetshiwe enokuqukethwe okuphansi kwekhabhoni iye yathuthukiswa, okunganciphisa kakhulu izindleko zokukhiqiza i-graphite enwetshiwe, ngaleyo ndlela ithathe indawo ye-asbestos ngezinga elikhulu futhi ikhule isidingo. Ngakolunye uhlangothi, uma izinto zokuvala zepulasitiki, zerabha kanye nensimbi zingashintshwa ngokwengxenye, isidingo sasekhaya sonyaka sezinto zokuvala i-graphite enwetshiwe sizoba sikhulu.
Embonini yezimoto, i-gasket ngayinye yekhanda lesilinda semoto, i-air intake kanye ne-exhaust port gasket ngayinye idinga cishe u-2 ~ 10kg we-graphite enwetshiwe, kanti njalo ngezimoto eziyi-10,000 idinga amathani angu-20 ~ 100 we-graphite enwetshiwe. Imboni yezimoto yaseShayina ingene enkathini yentuthuko esheshayo. Ngakho-ke, isidingo saminyaka yonke sezwe lami sezinto zokuvala i-graphite enwetshiwe sisalokhu sinombono oqondile.
