I-graphite eyandisiweyo, eyaziwa ngokuba yi-vermicular graphite, yi-crystalline compound esebenzisa iindlela zomzimba okanye zeekhemikhali ukudibanisa ii-reactants ezingezizo iikhabhoni zibe zizinto ze-nanocarbon ezihlanganisiweyo ngokwendalo kwaye zidityaniswe ne-carbon hexagonal network planes ngelixa igcina isakhiwo se-Graphite. Ayigcini nje ngokugcina iipropati zomzimba nezekhemikhali ezibalaseleyo ze-graphite, ezinje ngokumelana nobushushu obuphezulu, ukumelana nokugqwala, i-neutron flux, i-X-ray kunye ne-gamma-ray irradiation yexesha elide. Ikwanazo neepropati zomzimba nezekhemikhali ezibalaseleyo, ezinje ngokulingana okuphantsi kokungqubana, ukuzithambisa okuhle, ukuqhuba kombane kunye nobushushu, kunye ne-anisotropy. Ngaphezu koko, ngenxa yokusebenzisana phakathi kwezinto ezihlanganisiweyo kunye nomaleko we-graphite, i-graphite eyandisiweyo ibonisa iipropati ezintsha ezingenazo i-graphite ecocekileyo kunye nezinto ezidibeneyo, kwaye yoyisa ubuqhophololo kunye nokuxhathisa kwempembelelo ye-graphite yendalo. Abahleli be-graphite abalandelayo be-Furuite babelana ngentshayelelo yeendlela zokwenziwa kwe-industrial kunye nokusetyenziswa kwe-graphite eyandisiweyo:
1. Iindlela zokwenziwa ezisetyenziswa kakhulu kushishino
①Ukunyibilika kweekhemikhali
Iingenelo: Indlela yokucoca ngekhemikhali yindlela esetyenziswa kakhulu neyaziwayo kushishino. Ke ngoko, ineengenelo ezicacileyo, iteknoloji evuthiweyo kunye nexabiso eliphantsi.
Ingxaki: I-arhente edibanisayo idla ngokuba yi-sulfuric acid exineneyo, etya isixa esikhulu se-asidi. Kukho ungcoliseko lwegesi oluyingozi lweSox kwinkqubo yokuvelisa, kwaye iintsalela kwimveliso zikwadla ngokugqwala izixhobo zokwenziwa.
②Ukunyibilika kwe-electrochemical
Njenge-chemical oxidation, yenye yeendlela eziqhelekileyo zokwenziwa kwe-industrial graphite.
Iingenelo: Akukho mfuneko yokongeza ii-oxidants ezinamandla, ezifana nee-asidi ezinamandla, kwaye impendulo ingalawulwa ngokulungelelanisa iiparameters ezifana nombane kunye ne-voltage. Izixhobo zokwenziwa zilula, ubungakanani bokwenziwa bukhulu, i-electrolyte ayingcoliswanga, kwaye inokusetyenziswa kwakhona.
Iingxaki: Uzinzo lwemveliso eyenziweyo luphantsi kunezinye iindlela, ezifuna izixhobo eziphezulu, kwaye kukho izinto ezininzi ezichaphazela umgangatho wemveliso. Ngamanye amaxesha, umthamo owandisiweyo wemveliso uncipha kakhulu ngenxa yokunyuka kobushushu obungqongileyo. Ukongeza, kukho iimpendulo ezingalindelekanga kwimisinga ephezulu kwizisombululo zamanzi, ngoko ke kunzima ukufumana iikhompawundi zokuqala.
2. Amashishini aphambili emveliso kunye namandla emveliso
Imveliso yeemveliso zegrafiti ezandisiweyo kwilizwe lam ikhule ukusuka kwinqanaba lokuqala ukuya kubavelisi abangaphezu kwe-100, kunye nemveliso yonyaka emalunga neetoni ezingama-30,000, kwaye uxinaniso lwemarike luphantsi. Kwakhona, uninzi lwabavelisi ikakhulu zizizalisi zesitywina ezikumgangatho ophantsi, ezingasetyenziswa rhoqo kwizitywina zeemoto kunye nezibane zeenqwelo moya zenyukliya. Nangona kunjalo, ngophuhliso lwetekhnoloji yasekhaya, umlinganiselo weemveliso eziphezulu uya kunyuka kancinci.
3. Imfuno yemarike kunye noqikelelo lwezinto zokutywina
Okwangoku, i-graphite eyandisiweyo isetyenziswa kakhulu njengezinto zokuvala iimoto, ezifana nee-cylinder gaskets, ii-intake kunye nee-exhaust port gaskets, njl. Izinto zokuvala i-graphite ezandisiweyo kwilizwe lam zisetyenziswa kakhulu njengezinto zokuvala. Okwangoku, i-graphite eyandisiweyo enomxholo ophantsi wekhabhoni iye yaphuhliswa, nto leyo enokunciphisa kakhulu iindleko zemveliso ye-graphite eyandisiweyo, ngaloo ndlela ithathe indawo ye-asbestos ngomlinganiselo omkhulu kwaye imfuno iyanda. Kwelinye icala, ukuba izinto zokuvala zeplastiki, zerabha kunye nesinyithi zinokutshintshwa ngokuyinxenye, imfuno yasekhaya yonyaka yezixhobo zokuvala i-graphite eyandisiweyo iya kuba nkulu.
Kwishishini leemoto, i-gasket nganye yentloko yesilinda yemoto, i-air intake kunye ne-exhaust port gasket nganye ifuna malunga ne-2 ~ 10kg ye-graphite ekhutshiweyo, kwaye nganye imoto ezili-10,000 ifuna iitoni ezingama-20 ~ 100 ze-graphite ekhutshiweyo. Ishishini leemoto laseTshayina lingene kwixesha lophuhliso olukhawulezileyo. Ke ngoko, imfuno yonyaka yelizwe lam yezinto zokuvala i-graphite ekhutshiweyo isasebenza kakuhle.
