Kuchena kweupfu hwegrafiti muzvigadzirwa zve graphite electrode chinhu chakakosha cheupfu hwegrafiti uye chinhu chinofanira kunzwisiswa nevashandisi ve graphite powder nevanoshandisa graphite powder. Graphite pachayo imineral ye crystalline yechisikigo, uye huwandu hwekabhoni hwakagadzika ndiyo chiratidzo chikuru chekuchena kweupfu hwegrafiti. Usati wabva mufekitori kana kuti waenderera mberi nekugadzirisa, upfu hwegrafiti hunofanira kuedzwa zvakasiyana-siyana, pakati pazvo bvunzo yekuchena kweupfu hwegrafiti inokosha.
Kuyera kuchena kweupfu hwegrafiti ndekwekuona huwandu hwekabhoni yakagadzika muupfu hwegrafiti. Nekuti graphite ine kugadzikana kwakanaka kwemakemikari patembiricha yemumba, hazvidikanwi kuziva zvakananga huwandu hwekabhoni hwayo. Hunhu hwekabhoni hunowanzo kuverengerwa nehuwandu hwekupisa kwakanyanya kwezvinhu zvichaedzwa. Kureva kuti, huwandu hwekabhoni hunoverengerwa zvichibva pakukosha kwenhamba yegraphite iri kuoxidized kuita carbon dioxide uye kuvhiringidzika pakupisa kwakanyanya. Nzira yekuverenga kuchena kweupfu hwegrafiti ndeyekuti kabhoni yakagadzika (%) = 100%- ash (%)- volatil matter (%).
Zvigadzirwa zvemakemikari zvezuva nezuva zveGraphene
Nzira chaiyo yekuedza kuchena kweupfu hwegrafiti ndeiyi inotevera: Yera nemazvo sampuli mbiri dzeupfu hwegrafiti ye1-gram uchishandisa electronic analytical balance, wodziisa zvakateerana mu double-lid porcelain crucible ne graphite boat ine huremu hunozivikanwa. Omesa muovheni yekuomesa ye105℃ kusvika yasvika pahuremu hunodiwa, wonyora huremu hweG1 neG2 hweupfu hwegrafiti zvakateerana. Isa double-lid porcelain crucible ine graphite powder muchoto chinodziya zvakanyanya wochichengeta patembiricha yakaenzana ye950℃ kwemaminitsi manomwe uchishandisa stopwatch. Wobva waibvisa woitonhodza kusvika patembiricha yakaenzana mu desiccator. Yera upfu hwegrafiti seG3. Tora graphite boat ine graphite powder woichengeta patembiricha yakaenzana ye950℃ kwemaminitsi makumi mapfumbamwe muchoto chinodziya zvakanyanya. Wobva wabvisa graphite powder woitonhodza kusvika patembiricha yakaenzana yemukamuri. Panguva ino, huremu hwezvinhu zvacho huremu hweash G4. Kutanga, verenga zvinhu zvinoshanduka zveupfu hwegraphite V (%)= (G1-G3)/ G1× 100%. Saka, fomura yekuverenga kuchena kweupfu hwegraphite C(%)=[(G2-V- G4)/ G2]× 100% inowanikwa. Kuchena kweupfu hwegraphite chinhu chakakosha zvikuru, kunyanya pakuedza kuchena kweupfu hwegraphite hwakachena. Kana chete upfu hwegraphite huchisangana nezvinodiwa zvekuchena kweupfu hwegraphite hwakachena ndipo panogona kuonekwa sechigadzirwa chakakodzera. Indasitiri yegraphite yemold yakachinja zvishoma nezvishoma kubva kumuenzaniso wekare kuenda kune imwe nzira yakasiyana-siyana nekukura kwayo. Hazvichawanzoitiki kuti mabhizinesi abatane uye apfuure miganhu kuti ararame uye akure. Munzvimbo yezvinodiwa mune ramangwana, kushandiswa kuchavawo nekutsvaga zvigadzirwa kwakasarudzika uye kwehunyanzvi.
Electrode yeGraphite
Saka, indasitiri ye graphite mold iri kuchinja zvakanyanya kuti itevedzere mafambiro eThe Times uye kuvandudza nekuvandudza zvirimo zvechigadzirwa. Kugadzirwa kwebhizinesi kunoda hunyanzvi. Mumwe muparidzi akataura kuti, mumamiriro ezvinhu aripo iye zvino, mabhizinesi mashoma kwazvo anogona kuita basa rakanaka mukuvandudza maindasitiri akasiyana. Sezvakaita mataira anofukidza graphite molds, graphite molds anofukidza mataira, makabati anofukidza graphite molds, nezvimwewo. Mundima yega yega, kune zvipingamupinyi zvayo uye hunyanzvi hwayo, izvo zvisingakwanisike nyore nyore nebhizinesi rimwe chete. Kuunganidzwa nekuvandudzwa kwematarenda, matekinoroji uye nzira zvese zvinoda maitiro.
Kuratidzwa kweKitchen and Bathroom kwechi20 kwatanga. Vanhu vari mukati meindasitiri vakanyanya kutarisa pakugadzira graphite molds pavaikurukura nezvekuratidzwa kwekicheni nebathroom. Asi zvechokwadi, kicheni nebathroom hazviparadzanisike. Munguva yekuvandudzwa kwekuratidzwa mumakore mashoma apfuura, kunyanya nekuvhurwa kwakazara kweHall N, mabhizinesi emakabati, mabhizinesi emidziyo yekicheni, mabhizinesi edenga nevamwe vagadziri vese vakatamira, uye mabhizinesi akasiyana-siyana anotsigira akapindawo rimwe nerimwe, zvichiita kuti mabasa nepfungwa huru dzekuratidzira zvive zvakapfuma uye zvakakwana, uye purofiti inogona kuva yakakura!
Zvisinei, kubatanidzwa kwemaindasitiri kunoita sekusingadzivisike. Chikonzero chinoita kuti graphite molds, makabati, midziyo yekicheni uye denga zvionekwe panguva imwe chete yekuratidzira inyaya yekuda kwemusika nevatengi. Ehe, hunyanzvi uye kusiyanisa zvinhu pachazvo inyaya dzave dzichikura nenzira yekutaura. Shanghai Kitchen and Bathroom Exhibition ikozvino yapinda padanho idzva. Zvese zviri zviviri kuratidzwa nemabhizinesi zviri kugadzirira chinyararire shanduko. Iyi tsika idiki diki yekushandurwa kwe "Made in China". Pakuratidzwa uku kwakavhurwa musi wa3 Chikumi 2015, tinogona kuona zvimwe zviratidzo zve "Internet Plus", zvimwe zviratidzo zve "huchenjeri", uye maitiro matsva uye asina kunyanya kupindira.
