Zvakanakira zve graphite accessories uye magetsi ekudziya zvinhu zvevacuum vira

Nekuvandudzwa kweyero yevacuum vharafu yekupisa yekurapa choto, vacuum kupisa kurapwa kune yakasarudzika mabhenefiti, uye vacuum kupisa kurapwa kwave kudiwa nevanhu vari muindasitiri nekuda kweakatevedzana mabhenefiti senge degassing, degreasing, oxygen isina uye otomatiki. Nekudaro, zvakakosha kuti vacuum yekupisa yekupisa yevira ine yakakwira mwero wemagetsi ekudziya zvinhu, senge yakakwira-tembiricha deformation, kuputsika Volatilization yave chinhu chakakosha chinotadzisa kuvandudzwa.vacuum choto.
Kuti agadzirise dambudziko iri, indasitiri yakatendeudzira kutarisa kwayo kune graphite.Graphiteinogadzirwa nedzimwe simbi uye ine zvakanakira zvakanaka. Zvinonzwisiswa kuti graphite inenge yakakurumbira mumhando dzakasiyana dzevacuum kupisa kupisa mavira sechinhu chemagetsi chekudziya.
Zvadaro zvakanakira graphite vacuum kupisa kurapwa magetsi kudziyisa zvinhu
1) Kupisa kwekushisa kwepamusoro: nzvimbo yakanyunguduka yegraphite i3850 ± 50 ℃ uye nzvimbo yekubikira i4250 ℃. Kunyange kana yakapiswa ne-ultra-high tembiricha arc, kurasikirwa kwehuremu kuduku zvikuru uye coefficient yekuwedzera kwekushisa iduku zvikuru. Simba re graphite rinowedzera nekuwedzera kwekushisa. Pa2000 ℃, kusimba kwegraphite kwakapetwa kaviri.
2) Conductivity uye thermal conductivity: conductivity ye graphite yakapetwa ka100 kupfuura iyo yakawanda isiri-metallic minerals. Thermal conductivity inodarika iyo yesimbi, iron, lead nezvimwe zvinhu zvesimbi. The thermal conductivity inoderera nekuwedzera kwekushisa. Kunyangwe pakupisa kwakanyanya, graphite inova insulator. Graphite inogona kuitisa magetsi nekuti yega kabhoni atomu mugraphite inoumba matatu chete covalent zvisungo neimwekabhonimaatomu, uye atomu imwe neimwe yekabhoni ichiri kuchengetedza erekitironi imwe yemahara kuendesa mutero.
3) Lubricity: iyo lubrication performance yegraphite inoenderana nehukuru hwe graphite scale. Iyo yakakura chiyero, idiki iyo friction coefficient, uye zvirinani kuita kwekuzora. Kugadzikana kwemakemikari:graphiteine kugadzikana kwakanaka kwekemikari pakudziya kwekamuri uye inogona kuramba acid, alkali uye organic solvent corrosion.
4) Plasticity: graphite ine kusimba kwakanaka uye inogona kukuyiwa kuita mashizha matete. Thermal shock resistance: kana graphite ichishandiswa pakupisa kwekamuri, inogona kumira nekushanduka kwekushisa pasina kukuvara. Kana tembiricha ichichinja kamwe kamwe, huwandu hwegraphite hunochinja zvishoma uye kuputika hakuzoitika.
Paunenge uchigadzira uye uchigadzira iyo vacuum choto, isu tinofanirwa kufunga kuti kushorwa kwemagetsi kupisa chinhu chinochinja zvishoma nekushisa uye resistivity yakagadzikana, saka graphite ndiyo inofarirwa zvinhu.
