Izinzuzo zezesekeli ze-graphite nezinto zokushisa zikagesi zesithando somoya

Ngokuthuthuka kwezinga lesithando sokushisa se-vacuum valve, ukwelashwa kokushisa kwe-vacuum kunezinzuzo ezihlukile, futhi ukwelashwa kokushisa kwe-vacuum kuye kwathandwa ngabantu embonini ngenxa yochungechunge lwezinzuzo ezifana nokukhipha igesi, ukususa amafutha, ukungabi nomoya-mpilo kanye nokwenza izinto ngokuzenzakalelayo. Kodwa-ke, kuyaphawuleka ukuthi isithando sokushisa se-vacuum sinezinga eliphakeme lezinto zokushisa zikagesi, njengokuguquguquka kwezinga lokushisa eliphezulu, ukuqhekeka. Ukuguquguquka kwesimo sezulu kube yinto ebalulekile evimbela ukuthuthukiswa kwe-isithando somlilo se-vacuum.
Ukuze kuxazululwe le nkinga, imboni yaphendukela ekugxileni ku-graphite.I-Graphiteyenziwe ngezinye izinsimbi futhi inezinzuzo ezingenakuqhathaniswa. Kuyaqondakala ukuthi i-graphite ithandwa kakhulu ezinhlotsheni ezahlukene zezitofu zokwelapha ukushisa nge-vacuum njengento yokushisa kagesi.
Khona-ke izinzuzo zokwelashwa kokushisa kwe-graphite vacuum cleaner kagesi
1) Ukumelana nokushisa okuphezulu: iphuzu lokuncibilika kwe-graphite lingu-3850 ± 50 ℃ kanti iphuzu lokubilisa lingu-4250 ℃. Ngisho noma ishiswa yi-arc yokushisa ephezulu kakhulu, ukwehla kwesisindo kuncane kakhulu futhi i-coefficient yokwanda kokushisa incane kakhulu. Amandla e-graphite ayanda ngokwanda kwezinga lokushisa. Ku-2000 ℃, amandla e-graphite aphindwe kabili.
2) Ukuqhuba kanye nokuqhuba ukushisa: ukuqhubela kwe-graphite kuphakeme ngokuphindwe kayi-100 kunokwamaminerali ajwayelekile angewona awensimbi. Ukuqhuba ukushisa kudlula okwensimbi, insimbi, i-lead kanye nezinye izinto zensimbi. Ukuqhuba ukushisa kuyancipha ngokwanda kokushisa. Ngisho noma izinga lokushisa liphezulu kakhulu, i-graphite iba yisivikelo. I-Graphite ingaqhuba ugesi ngoba i-athomu ngayinye yekhabhoni ku-graphite yakha izibopho ezintathu kuphela ze-covalent nezinyeikhabhoniama-athomu, futhi i-athomu ngayinye yekhabhoni isagcina i-electron eyodwa yamahhala yokudlulisa ishaja.
3) Ukugcotshwa: ukusebenza kokugcotshwa kwe-graphite kuncike kusayizi wesikali se-graphite. Uma isikali sikhulu, i-friction coefficient iba ncane, futhi ukusebenza kokugcotshwa kuba ngcono. Ukuqina kwamakhemikhali:i-graphiteinokuqina okuhle kwamakhemikhali ekushiseni kwegumbi futhi ingamelana nokugqwala kwe-asidi, i-alkali kanye ne-organic solvent.
4) Ukuqina: i-graphite inokuqina okuhle futhi ingagaywa ibe amashidi amancane kakhulu. Ukumelana nokushaqeka kokushisa: uma i-graphite isetshenziswa ekushiseni kwegumbi, ingamelana noshintsho olukhulu lokushisa ngaphandle kokulimala. Uma izinga lokushisa lishintsha ngokuzumayo, umthamo we-graphite ushintsha kancane futhi ngeke kwenzeke imifantu.
Lapho siklama futhi sicubungula isithando somlilo esingenagesi, kufanele sicabangele ukuthi ukumelana kwento yokushisa kagesi akushintshani kangako ngokushisa futhi ukumelana kwayo kuzinzile, ngakho-ke i-graphite iyinto ekhethwayo.
