Nhanganyaya ye graphite flexible felt

Graphite yekupisa kwakanyanya ine huremu hwakareruka, kukanganiswa kwakanaka, huwandu hwakawanda hwekabhoni,kuramba kupisa kwakanyanya, hapana kuvhiringidzika kwemhepo pakupisa kwakanyanya,kuramba nguradiki, dikikufambiswa kwemhepo inopisauye kuchengetedza chimiro chayo zvakanyanya.

Chigadzirwa ichi chine zvakanakira zvinotevera: mushure mekurapwa kwekupisa kwakanyanya kwe1800 ~ 2500 ℃, musiyano wekupisa pakati pemapoinzi maviri efelt haupfuuri 50 ℃, saka mashandiro echigadzirwa akagadzikana. Nekuti kugadzirwa kwacho kunoramba kuripo, kunogona kuve nechokwadi chekuti felt yakagadzirwa zvakaenzana muhupamhi nehurefu hwese.

Zvichienzaniswa nekabhoni yakanzwaYakarapwa patembiricha yakaderera (pasi pe900 ℃), graphite yakanzwa kuti yakarapwa patembiricha yepamusoro (pamusoro pe2200 ℃) ine zvakanakira zvinotevera:

（1) Kunyungudika kwemvura nemweya wemamwe magasi pa graphite felt kwakaderera nekaviri pane kunyungudika kwekabhoni kwakabatwa patembiricha yakaderera. Kune mimwe midziyo yemidziyo yakavharwa inoda kunyungudika, kuchena kwemhepo ndicho chinhu chakakosha. Zvisinei, nekuda kwekunyungudika kwakanyanya kwekabhoni yakabatwa patembiricha yakaderera, zvakaoma kunyungudika mumudziyo.

（2) Girafu ine simba guru rekudzivirira kupisa. Maumbirwo ekabhoni isina girafu imhando yechimiro chechikamu chisina kurongeka. Kuvapo kwezvikanganiso zvakasiyana-siyana zvemaumbirwo kunoita kuti nzvimbo yayo yechikamu ive yakakura, uye zviri nyore kurwiswa nemaatomu eokisijeni uye kuoxidized. Lattice yakakwana uye kurongeka kwetatu-dimensional kwegirafu yakafemerwa mushure mekurapwa kwekupisa kwakanyanya kunoderedza zvakanyanya nzvimbo yechikamu uye kunoita kuti zvisave nyore kurwiswa nemaatomu eokisijeni, nokudaro zvichiwedzera zvikuru kugona kweantioxidant.

（3) Kuchena kwegraphite felt kwakakwira, uye huwandu hwekabhoni hunopfuura 99.5%. Hunhu hwekabhoni hwekabhoni yakagadziriswa tembiricha yakaderera kazhinji hunenge huri pasi pe93%, izvo zviri nyore kukonzera kusvibiswa kwezvakatipoteredza muchoto.

Muchidimbu, girafiti yakabatwa nekupisa kwakanyanya ine simba riri nani uye hupenyu hurefu hwebasa pane girafiti yakabatwa nekupisa kwakaderera.
