Zeziphi iimpawu zegraphite eyandiswayo emva kokufudumeza kwigraphite eyandiswayo?

Iimpawu zokwandiswa kweiphepha legraphite elandisiweyozahlukile kwezinye ii-arhente zokwandisa. Xa ishushu kwiqondo lobushushu elithile, igraphite eyandisiweyo iqala ukwanda ngenxa yokubola iikhompawundi efunxwe kwileti interlayer, leyo ibizwa ngokuba ubushushu lokuqala ukwanda. Iyanda ngokupheleleyo kwi-1000 ℃ kwaye ifikelele kumthamo omkhulu. Umthamo wokwandisa unokufikelela kumaxesha angaphezu kwama-200 exabiso lokuqala. Igraphite eyandisiweyo ibizwa ngokuba yigraphite eyandisiweyo okanye intshulube yegraphite, eguqukayo ukusuka kwimilo yeflake yokuqala ukuya kwimilo yeentshulube ezinoxinano oluphantsi, yenze umaleko olungileyo kakhulu wokugquma kwe-thermal. Igraphite eyandisiweyo ayingomthombo wekhabhoni kuphela kwinkqubo yokwandisa, kodwa kunye ne-insulating layer. Inokuba nempumelelokhusela ubushushu. Emlilweni, uneempawu zokukhutshwa kobushushu obuphantsi, ukulahleka kobunzima obuncinci kunye negesi encinci ye-flue.

Zeziphi iimpawu zegraphite eyandiswayo emva kokufudumeza kwigraphite eyandiswayo?

Iimpawu zegraphite eyandisiweyo

① Ukumelana noxinzelelo olunamandla,ukuba bhetyebhetye, iplastiki kunye nokuzithambisa;

② Ukuchasana okunamandla kubushushu obuphezulu, obuphantsi,umhlwakunye nemitha;

③ Iimpawu zenyikima ezomeleleyo ngokugqithisileyo;

④ Yomelele kakhuluconductivity;

⑤Iipropathi ezinamandla zokuchasa ukuguga kunye nokuchasana nokuphazamiseka.

⑥ Inokumelana nokunyibilika kunye nokungena kweentsimbi ezahlukeneyo;

⑦ Ayinatyhefu, ayinayo nayiphi na i-carcinogens kwaye ayinabungozi kwindalo.

Izalathiso ezininzi zophuhliso lwegraphite eyandisiweyo zimi ngolu hlobo lulandelayo:

1. Igraphite eyandisiweyo ngeenjongo ezizodwa

Uvavanyo lubonisa ukuba iintshulube zegraphite zinomsebenzi wokufunxa amaza ombane. Igraphite eyandisiweyo kufuneka ihlangabezane nezi mfuno zilandelayo: (1) iqondo lokushisa eliphantsi lokuqala kunye nomthamo omkhulu wokwandisa; (2) Iimpawu zeekhemikhali zizinzile, zigcinwe iminyaka emi-5, kwaye umlinganiselo wokwandisa ngokusisiseko awuboli; (3) Umphezulu wegraphite eyandisiweyo ayithathi hlangothi kwaye ayinayo i-corrosion kwi-cartridge case.

2. Igraphite eyandisiweyo yegrafu

Amasuntswana amancinane egraphite eyandisiweyo ikakhulu ibhekiselele 300 mesh enwebekayo igraphite nomthamo wokwandiswa 100ml / g. Le mveliso isetyenziswa ikakhulu kwi-flame retardantiingubo, efunwa kakhulu.

3. Igraphite eyandisiweyo enobushushu obuphezulu bokwandiswa kokuqala

Ubushushu bokuqala bokwandiswa kwegraphite eyandisiweyo kunye nobushushu bokuqala bokwandiswa okuphezulu yi-290-300 ℃, kunye nomthamo wokwandiswa ngu-≥ 230ml / g. Olu hlobo lwegraphite eyandisiweyo isetyenziswa ikakhulu kwidangatye lokubuyiswa kweeplastiki zobunjineli kunye nerabha.

4. Umphezulu oguqulwe igraphite

Xa igraphite eyandisiweyo isetyenziswa njengesixhobo sokubuyiswa komlilo, ibandakanya ukuhambelana phakathi kwegraphite kunye namanye amacandelo. Ngenxa ye-mineralization ephezulu ye-graphite surface, ayikho i-lipophilic okanye i-hydrophilic. Ngoko ke, umphezulu wegraphite kufuneka uguqulwe ukusombulula ingxaki yokuhambelana phakathi kwegraphite kunye namanye amacandelo. Kuye kwacetywa ukuba kwenziwe mhlophe umphezulu wegraphite, oko kukuthi, ukugubungela umphezulu wegraphite ngefilimu emhlophe eqinileyo, eyingxaki enzima ukuyicombulula. Ibandakanya i-membrane chemistry okanye i-surface chemistry. Ilabhoratri inokukwazi ukwenza oko, kwaye kukho ubunzima kwimizi-mveliso. Olu hlobo lwegraphite emhlophe enwebekayo isetyenziswa ikakhulu njengezogqumethelo zedangatye.

5. Iqondo lobushushu lokuqala elisezantsi kunye negraphite eyandisiweyo yobushushu obuphantsi

Olu hlobo lwegraphite eyandisiweyo luqala ukwandisa kwi-80-150 ℃, kwaye umthamo wokwandisa ufikelela kwi-250ml / g kwi-600 ℃. Ubunzima ekulungiseleleni intlanganiso yegraphite eyandisiweyo kulo mqathango zezi: (1) ukukhetha i-arhente yokunxibelelana efanelekileyo; (2) Ukulawula kunye nokulawula iimeko zokomisa; (3) Ukuqinisekiswa kokufuma; (4) Isisombululo seengxaki zokusingqongileyo.
