I-graphite enwetshiwe, eyaziwa nangokuthi i-Vermicular graphite, iyingxenye ye-crystalline esebenzisa izindlela ezingokomzimba noma zamakhemikhali zokuhambisa izindiza ze-graphitic ezingekho emthethweni ze-graphitic ezihlanganisiwe ze-graphitic ezihlanganisiwe ngenkathi zihlangana nesakhiwo se-grapbon hexager. Akugcini ngokugcina kuphela impahla enhle kakhulu yenyama kanye namakhemikhali ye-graphite, njengokumelana okuphezulu kwamazinga okushisa, ukumelana nokugqwala, i-flux ye-neutron, i-X-ram kanye ne-gamma-ray nerradiation yesikhathi eside. Iphinde ibe nezakhiwo ezinhle kakhulu zomzimba nezamakhemikhali, njenge-coefficial ephansi yokuphikisana, ukuzilibazisa okuhle kokuzithaba, ukuvumelanisa nogesi, ne-anotropy. Ngaphezu kwalokho, ngenxa yokusebenzisana phakathi kwezinto eziphakathi nendawo kanye ne-graphite ungqimba, i-graphite enwetshiwe ekhombisa izakhiwo ezintsha i-pristine graphite nezinto zokufunda eziphakathi nendawo ezingenazo, futhi ziyeqeni ukumelana nokuphikiswa komthelela we-graphite yemvelo. Abahleli be-Fruuite Graphite abalandelayo babelana ngokwazisa kwezindlela zezinhlobo zezimboni kanye nokusebenzisa i-graphite enwetshiwe:
1. Izindlela zokwenziwa ezivame ukusetshenziswa embonini
①Chemical Oxidation
Izinzuzo: I-Chemical Oxidation iyindlela esetshenziswa kabanzi futhi esungulwe kahle embonini. Ngakho-ke, inezinzuzo ezisobala, ubuchwepheshe obuvuthiwe kanye nezindleko eziphansi.
Ububi: I-ejenti yokuxhumana imvamisa i-sulfuric acid, edla inani elikhulu le-acid. Kukhona ukungcoliswa kwegesi okulimazayo kwe-SOX kwinqubo yokukhiqiza, futhi izinsalela emkhiqizweni nazo zilungisa imishini yokuhlanganiswa.
②Electrochemical oxidation
Njenge-oxidation yamakhemikhali, kungenye yezindlela ezivamile zokuhlanganiswa kwezimboni zegrafu ezandisiwe.
Izinzuzo: Akunasidingo sokungeza ama-oxidants aqinile, njengama-acid aqinile, futhi ukusabela kungalawulwa ngokulungiswa kwamapharamitha anjenge kwamanje nogesi. I-synthesis imishini elula, inani le-synthesis likhulu, i-electrolyte ayingcolisiwe, futhi ingaphinde isetshenziswe kabusha.
Okubi: Ukuqina komkhiqizo owenziwe ampofu kunezinye izindlela, ezidinga imishini ephezulu, futhi kunezinto eziningi ezithinta ikhwalithi yomkhiqizo. Kwesinye isikhathi, ivolumu eyandisiwe yomkhiqizo incishiswa kakhulu ngenxa yokwanda kokushisa okukhona. Ngaphezu kwalokho, kukhona ukusabela okuseceleni kwemisinga ephakeme kwizixazululo zamanzi, ngakho-ke kunzima ukuthola amakhompiyutha okuqala.
2. Amabhizinisi Okukhiqiza Main kanye namandla Okukhiqiza
Ukukhiqizwa kwemikhiqizo ye-graphite enwetshiwe ezweni lami kukhule kusukela esigabeni sokuqala kubakhiqizi abangaphezu kwe-100, ngokukhipha unyaka wonke amathani angama-30,000, futhi ukugxishwa kwemakethe kuphansi. Futhi, iningi labakhiqizi lingama-fillers seal end ephansi, akuvamile ukuthi asetshenziswe ezimotweni zezimoto kanye nezibani zezindiza zenuzi. Kodwa-ke, ngokuthuthukiswa kobuchwepheshe bekhaya, ingxenye yemikhiqizo ephezulu kakhulu izokhula kancane kancane.
I-3. Isidingo semakethe kanye nesibikezelo sezinto zokwakha uphawu
Njengamanje, i-graphite enwetshiwe isetshenziswa ikakhulukazi njengezinto zokwenziwa kokubekwa kwezimoto, njengama-cylinder gaskets, ukuthambisa kanye nama-gaskets e-graphite wokubopha, njll. Njengamanje, i-graphite enwetshiwe enokuqukethwe okuphansi kwekhabhoni iye yathuthukiswa, enganciphisa kakhulu izindleko zokukhiqiza zegrafu ezandisiwe, ngaleyo ndlela zibuyise ama-asbestos ngezinga elikhulu nesidingo esandayo. Ngakolunye uhlangothi, uma izinto zeplastiki, izinto zokubopha zensimbi nezinsimbi zingashintshwa ngokwengxenye, isidingo sonyaka sasekhaya sezinto zokubopha ze-graphite ezinwetshiwe zizoba zinkulu.
Embonini yezimoto, i-gasket ye-motooberle ye-bilide yemoto ngayinye, i-air yokuphuza kanye ne-purt port gasket idinga cishe i-2 ~ 10kg ye-graphite enwetshiwe, futhi zonke izimoto eziyi-10,000 zidinga ama-graphite anwetshiwe. Umkhakha wezimoto waseChina ungene esikhathini sokuthuthuka okusheshayo. Ngakho-ke, isidingo sonyaka wami sonyaka se-graphite seaving seaving esinwetshiwe sisenhloso kakhulu.
