Green silicon carbide uye dema silicon carbide: Misiyano yakadzika kupfuura ruvara
Mundima yakakura yezvigadzirwa zveindasitiri,green silicon carbideuyedema nesilicon carbide dzinowanzotaurwa pamwe chete. Ose ari maviri akakosha mabrasives anogadzirwa nekunyungudika kwekushisa kwepamusoro-soro mumavira ekupikisa ane zviwanikwa zvakaita sejecha requartz uye petroleum coke, asi mutsauko wavo wakanyanya kudarika misiyano yemavara pamusoro. Kubva pamisiyano yakadzikama yezvigadzirwa, kusvika pakusiyana kwemaitiro ekuita, kusvika kune mutsauko wakakura wemamiriro ekushandisa, misiyano iyi yakabatana yakaumba mabasa akasiyana ezviviri mumunda weindasitiri.
1 Musiyano mukuchena kwezvinhu uye chimiro chekristaro chinotarisa maitiro akasiyana ezviviri.
Green silicon carbideinogadzirwa nepetroleum coke nejecha requartz sezvinhu zvikuru, uye munyu unowedzerwa kuti ucheneswe. Kuburikidza nekuita uku, kusvibiswa kwemukati kunoderedzwa kusvika pamwero mukuru, uye kristaro inogara ine hexagonal system ine mipendero yakapinza uye makona. Iyo mbishi kugadzirwa kweiyo nhema silicon carbide iri nyore, uye hapana munyu unowedzerwa. Izvo zvisina kuchena zvakaita sesimbi nesilicon zvakasiiwa mune zvakabikwa zvinoita kuti zvimedu zvekristaro zvisakanganise muchimiro uye zvakatenderedzwa uye zvakagomara kumicheto nemakona.
2 Misiyano yezvakagadzirwa uye zvimiro zvinotungamira kune akasiyana emuviri maitiro ezviviri.
Panyaya yekuoma, iyo Mohs kuoma kwegreen silicon carbideinenge 9.5, yechipiri chete kudhaimondi, uye inogona kugadzira zvinhu zvekuoma zvakanyanya; nhema silicon carbide ingangoita 9.0, ine kuomarara zvishoma. Panyaya ye density, green silicon carbide ndeye 3.20-3.25g/cm³, ine dense chimiro; dema silicon carbide ndeye 3.10-3.15g/cm³, yakasununguka. Panyaya yekushanda, green silicon carbide ine kuchena kwepamusoro, yakanaka kupisa conductivity, magetsi conductivity uye yakakwirira tembiricha kuramba, asi ine brittle uye nyore kupaza mumicheto mitsva; dema silicon carbide ine zvishoma isina kusimba yekupisa conductivity uye magetsi conductivity, yakaderera brittleness, uye yakasimba particle kukanganisa kuramba.
3 Misiyano yemashandiro inosarudza chinangwa chekushandisa chezviviri.
Green silicon carbide inekuoma kwepamusorouye zvimedu zvinopinza, uye yakanaka pakugadzirisa kuomarara kwepamusoro uye kusimba kwakadzika: mumunda usiri wesimbi, unogona kushandiswa kukuya girazi, kucheka ceramic, semiconductor silicon wafers, uye kupenya kwesafire; mukugadzirwa kwesimbi, ine yakanakisa yepamusoro-chaiyo yekugadzirisa kuita kwezvinhu zvakaita semendi carbide uye simbi yakaomeswa, uye inoshandiswa zvakanyanya muzvigadzirwa zvakaita sekukuya mavhiri nemadhisiki ekucheka. Black silicon carbide inonyanya kuita yakaderera-kuomarara, yakakwirira-kuomarara zvinhu uye yakakodzera kugadzirwa kweasina-ferrous simbi uye refractory zvinhu senge simbi yakakandwa, mhangura nealuminium. Muzviitiko zvakakasharara senge deburring castings uye ngura kubviswa kwesimbi, yave sarudzo yakajairika muindasitiri nekuda kwekudhura kwayo.
Kunyange zvazvo green silicon carbide uyedema nesilicon carbidendezveiyo silicon carbide zvinhu system, yavo yemuviri uye makemikari zvimiro uye maitiro ekushandisa akasiyana zvakanyanya. Nekuenderera mberi kwekuvandudzwa kwezvinhu zvesainzi uye tekinoroji yekugadzira, girini silicon carbide uye nhema silicon carbide inotarisirwa kuwana yakawedzera dhizaini yekuwedzera munzvimbo dzepamusoro-tekinoroji dzakadai semiconductor kugadzira, kunyatso kugaya, uye simba idzva, ichipa yakakosha tsigiro yemhando yepamusoro indasitiri yemazuva ano.
