izindaba

I-graphite powder iwuhlobo lwe-mineral powder, ikakhulukazi eyakhiwe ngekhabhoni, ethambile futhi empunga emnyama;Inamafutha futhi ingangcolisa iphepha.Ubulukhuni buyi-1-2, futhi ubulukhuni bungakhula bufinyelele ku-3-5 ngokwanda kokungcola endaweni eqondile.Amandla adonsela phansi athile angu-1.9 ~ 2.3.Ngaphansi kwesimo sokuhlukanisa umoya-mpilo, indawo yawo yokuncibilika ingaphezu kuka-3000 ℃, futhi ingenye yamaminerali amelana kakhulu nokushisa.Ngaphansi kwezinga lokushisa elivamile, izakhiwo zamakhemikhali ze-graphite powder azinzile, azincibiliki emanzini, zihlanza i-asidi, zihlanza i-alkali kanye ne-organic solvent;Impahla inokumelana nokushisa okuphezulu kanye ne-conductivity, futhi ingasetshenziswa njengezinto zokugcoba eziphikisayo, eziqhubayo nezingagugi.

Amacala wokufaka izicelo
1. Isetshenziswa njengezinto eziphikisayo: i-graphite nemikhiqizo yayo inezici zokumelana nokushisa okuphezulu namandla aphezulu.Ngokuyinhloko zisetshenziselwa ukwenza izinsimbi ze-graphite embonini ye-metallurgical.Ekwenziweni kwensimbi, i-graphite ivame ukusetshenziswa njenge-ejenti evikelayo yezinsimbi zensimbi kanye nolwelwesi lwezithando zensimbi.
2. Isetshenziswa njengempahla eqhubayo: esetshenziswa embonini kagesi ukwenza ama-electrode, amabhulashi, ama-carbon rod, amashubhu ekhabhoni, isigxobo esihle se-mercury positive current, ama-graphite gaskets, izingxenye zocingo, kanye nokunameka kwamashubhu ezithombe zikamabonakude.
3. Njengempahla yokugcoba engagugi: i-graphite ivame ukusetshenziswa njengamafutha embonini yemishini.Amafutha okugcoba angeke asetshenziswe ngesivinini esikhulu, izinga lokushisa eliphezulu nokucindezela okuphezulu, kuyilapho izinto ezikwazi ukumelana ne-graphite zingasebenza ngaphandle kwamafutha okugcoba ngesivinini esikhulu sokushelela ku-(I) 200 ~ 2000 ℃.Imishini eminingi ethutha imidiya ebolayo yenziwa kabanzi ngezinto zegraphite zibe izinkomishi zepiston, izindandatho zokuvala nama-bearings.Abadingi ukwengeza amafutha okugcoba ngesikhathi sokusebenza.I-emulsion ye-graphite iphinde ibe yi-lubricant enhle yokucubungula insimbi eminingi (umdwebo wocingo nomdwebo wepayipi).

inhloso
Imboni yokugoqa
I-graphite inokusimama okuhle kwamakhemikhali.I-graphite ecutshungulwe ngokukhethekile inezici zokumelana nokugqwala, ukuguquguquka okuhle kwe-thermal kanye ne-permeability ephansi.Isetshenziswa kabanzi ukwenza izishintshisi zokushisa, amathangi okuphendula, ama-condensers, imibhoshongo evuthayo, imibhoshongo yokumuncwa, ama-coolers, izifudumezi, izihlungi kanye nemishini yokupompa.Isetshenziswa kabanzi ekukhiqizeni i-petrochemical, i-hydrometallurgy, i-asidi ne-alkali, i-synthetic fiber, iphepha kanye neminye imikhakha yezimboni, engasindisa izinto eziningi zensimbi.

Isetshenziswa njenge-casting, i-Foundry, i-molding kanye ne-high-temperature metallurgical materials: Ngenxa ye-coefficient encane yokwandisa okushisayo kwe-graphite kanye nekhono layo lokumelana nezinguquko zokupholisa okusheshayo nokushisa, ingasetshenziswa njengesikhunta se-glassware.Ngemva kokusetshenziswa kwe-graphite, insimbi eyinsimbi ingathola usayizi onembile wokuphonsa, izinga eliphezulu lokuqeda, futhi ingasetshenziswa ngaphandle kokucubungula noma ukucubungula okuncane, ngaleyo ndlela ilondoloze insimbi eningi.Ukuze kukhiqizwe i-carbide enosimende kanye nezinye izinqubo ze-powder metallurgy, izinto ze-graphite zivame ukusetshenziselwa ukwenza izikebhe ze-ceramic zokucindezela nokucwilisa.I-crystal yokukhula kwe-silicon ye-monocrystalline, isitsha sokucwenga sesifunda, i-bracket clamp, i-heater induction, njll. zonke zenziwe nge-graphite ehlanzekile kakhulu.Ngaphezu kwalokho, i-graphite ingasetshenziswa njengepuleti lokufaka i-graphite kanye nesisekelo sokuncibilika kwe-vacuum, ishubhu yesithando sokushisa esiphezulu sokushisa, induku, ipuleti, i-lattice nezinye izingxenye.

I-graphite ingaphinda ivimbele ukukala kwe-boiler.Ukuhlolwa kweyunithi efanelekile kubonisa ukuthi ukwengeza inani elithile lempushana ye-graphite (cishe amagremu angu-4~5 ngethani lamanzi) emanzini kungavimbela ukukalwa kwendawo yebhayela.Ngaphezu kwalokho, ukumbozwa kwe-graphite kushimula wensimbi, uphahla, ibhuloho kanye nepayipi kungavimbela ukugqwala nokugqwala.

I-graphite ingasetshenziswa njengomthofu wepensela, i-pigment kanye ne-ejenti yokupholisha.Ngemuva kokucubungula okukhethekile, i-graphite ingenziwa ibe yizinto ezihlukahlukene ezikhethekile zeminyango yezimboni efanele.

Ngaphezu kwalokho, i-graphite iphinde ibe i-ejenti yokupholisha kanye ne-ejenti yokulwa nokuvinjelwa kwengilazi nephepha embonini yokukhanya, kanye nempahla eluhlaza engabalulekile ekwenzeni amapensela, uyinki, upende omnyama, uyinki, amadayimane okwenziwa namadayimane.Kuyinto enhle yokonga amandla nokuvikela imvelo, esetshenziswe njengebhethri lemoto e-United States.Ngokuthuthuka kwesayensi yesimanje, ubuchwepheshe kanye nezimboni, insimu yokusetshenziswa kwegraphite isakhula.Sekuyimpahla ebalulekile yokusetshenziswa kwezinto ezintsha eziyinhlanganisela emkhakheni wezobuchwepheshe obuphezulu futhi idlala indima ebalulekile emnothweni wezwe.

Ukugoqa ukuvikela kwezwe
Isetshenziswa embonini yamandla e-athomu kanye nemboni yezokuvikela kazwelonke: i-graphite inomodareyitha omuhle we-neutron ukuze isetshenziswe kuma-athomu, kanti i-uranium-graphite reactor iwuhlobo lwe-athomu esetshenziswa kakhulu.Impahla eyehlisa izinga kureactor yenuzi esetshenziswa njengamandla kufanele ibe nendawo ephezulu yokuncibilika, ukuzinza kanye nokumelana nokugqwala.I-graphite ingahlangabezana ngokugcwele nezimfuneko ezingenhla.Ukuhlanzeka kwe-graphite esetshenziswa njenge-reactor ye-athomu kuphezulu kakhulu, futhi okuqukethwe okungcolile akufanele kudlule inqwaba yama-PPM.Ikakhulukazi, okuqukethwe kwe-boron kufanele kube ngaphansi kuka-0.5PPM.Embonini yezokuvikela kazwelonke, i-graphite iphinde isetshenziselwe ukwenza umlomo wombhobho werokhethi kaphethiloli oqinile, i-nose cone of missile, izingxenye zemishini yokuhamba emkhathini, izinto zokuvala ezishisayo kanye nezinto ezilwa nemisebe.
