Upfu hwegirafiti hunogona kushandiswa sepenzura, saka sei upfu hwegirafiti huchigona kushandiswa sepenzura? Unozviziva here? Verenga nemupepeti!
Chekutanga, hupfu hwegirafiti hwakapfava uye huri nyore kucheka, uye hupfu hwegirafiti hunonyorovawo uye huri nyore kunyora; Nezvekuti nei penzura ye2B ichifanira kushandiswa pabvunzo yekupinda kukoreji, kufambiswa kwayo kunofanira kushandiswa. Chechipiri, maererano nehunhu hwemakemikari, hupfu hwegirafiti hunoumbwa nechinhu cheC, uye hunhu hwemakemikari hwechinhu cheC hwakagadzikana patembiricha yemumba, saka kushandisa penzura yegirafiti kurekodha mafaira kunogona kuchengetedza nguva yakareba.
Upfu hwegrafiti hune hunhu hunotevera hunokosha nekuda kwechimiro chayo chakakosha:
1) Kudzivirira kupisa kwakanyanya: Graphite powder ine poindi yekunyunguduka ye3850 50℃ uye poindi yekufashaira ye4250℃. Kunyangwe ikapiswa nekupisa kwakanyanya, kudzikira kwayo uremu uye thermal expansion coefficient idiki kwazvo. Simba regraphite powder rinowedzera nekuwedzera kwekupisa, uye simba regraphite powder rinopetwa kaviri pa2000℃.
2) Kufambiswa kwemhepo nekupisa: Kufambiswa kwemhepo neupfu hwegrafiti kwakapetwa zana kupfuura kwesimbi dzisiri dzesimbi. Kufambiswa kwemhepo nekupisa kunopfuura kwesimbi dzakadai sesimbi, simbi nelead. Kufambiswa kwemhepo nekupisa kunoderera nekuwedzera kwekupisa, uye kunyangwe pakupisa kwakanyanya, upfu hwegrafiti hunova insulator. Upfu hwegrafiti hunogona kufambisa magetsi nekuti atomu yega yega yekabhoni muupfu hwegrafiti inoumba chete ma covalent bonds matatu nemamwe maatomu ekabhoni, uye atomu yega yega yekabhoni ichiri kuchengetedza elektroni imwe chete yemahara yekufambisa.
3) Kunyorovesa: Hunhu hwekunyorovesa hweupfu hwegrafiti hunoenderana nehukuru hwemakero eupfu hwegrafiti. Kana zviyero zvakakura, friction coefficient idiki uye hunhu hwekunyorovesa hunowedzera kunaka.
4) Kugadzikana kwemakemikari: Graphite powder ine kugadzikana kwakanaka kwemakemikari patembiricha yemumba, uye inogona kuramba ngura yeacid, alkali uye organic solvent.
5) Kupfava: Upfu hwegirafiti hwakasimba uye hunogona kukuyiwa kuita zvidimbu zvitete.
6) Kusabatwa nekupisa: Upfu hweGraphite hunogona kutsungirira kuchinja kukuru kwekupisa patembiricha yemumba pasina kukuvara. Kana tembiricha ikachinja kamwe kamwe, huwandu hweupfu hweGraphite hahuchinji zvakanyanya uye hahuzoitiki kuputika.
Tenga hupfu hwegrafiti, tinokugamuchirai kuQingdao Furuite Graphite Factory, tichakupai basa rinogutsa, kuitira kuti musazonetseka!
