Kodi kugwiritsa ntchito graphite crucible ndi kotani?

Kodi chophikira cha graphite n'chiyani?

Chophimba cha graphitendi gawo lofunika kwambiri la mafakitale, lomwe limagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana a mafakitale, monga zitsulo, kuponyera, makina, chemistry, semiconductor, ndi zina zotero. Ndi chosinthira kutentha chabwino komanso chowongolera kutentha, chomwe chingathe kuyendetsa bwino kutentha ndi magetsi popanga zinthu ndipo chingathe kusunga zinthu zambiri. Pakupanga semiconductor, graphite crucible imagwira ntchito yofunika kwambiri ndipo ndi imodzi mwa zida zofunika kwambiri popanga semiconductor.

Kodi mitundu ndi makhalidwe a graphite crucibles ndi ati?

Pali mitundu yambiri ya zoyikira za graphite, ndipo pali zoyikira za graphite zoyenera zochitika zosiyanasiyana, monga zoyikira zozungulira, zoyikira za sikweya, zoyikira zophatikizika, ndi zina zotero. Zoyikira za graphite zosiyanasiyana zimakhala ndi makhalidwe osiyanasiyana, koma zonse zimakhala ndi kutentha kwabwino komanso kuyendetsa bwino magetsi, zomwe zingathandize bwino magwiridwe antchito a zida.

Miyala ya graphite ikhozanso kugawidwa m'magulu mwatsatanetsatane malinga ndi malo osiyanasiyana ogwiritsira ntchito:
1. Chophikira wamba: choyenera kusungunuka, kutenthetsa ndi kusunga kutentha kwa zitsulo ndi aloyi wamba.
2. Chophimba chotentha kwambiri: choyenera kusungunula zitsulo zosagwira ntchito ndi zinthu zina zosungunula pa kutentha kwambiri, monga tungsten, molybdenum, tantalum, ndi zina zotero.
3. Chopangira zinthu: chimagwiritsidwa ntchito popanga ndi kukonza zinthu zoyera kwambiri, monga zinthu za semiconductor, zinthu zadothi, ndi zina zotero.
4. Chotsukira cha vacuum: choyenera kutentha ndi kusungunula m'malo opanda vacuum, chomwe chimagwiritsidwa ntchito makamaka pokonzekera zipangizo zapadera komanso kusungunula zitsulo zoyera kwambiri.

Zipangizo zopangira graphite crucible zimakhala ndi kukana kutentha kwambiri komanso kukhazikika kwa mankhwala. Zingagwiritsidwe ntchito kutentha kwambiri popanda kusinthika kapena kuwonongeka chifukwa cha kutentha kwambiri. Nthawi yomweyo, graphite crucible imakhalanso ndi kukana dzimbiri bwino ndipo imatha kukana kuwonongeka kwa mankhwala osiyanasiyana, motero kuonetsetsa kuti zipangizo za semiconductor zili bwino popanga.

Kodi kugwiritsa ntchito kwakukulu kwa ma graphite crucibles mu semiconductor ndi kotani?

Mu njira yopangira semiconductor,mipiringidzo ya graphiteamagwiritsidwa ntchito makamaka kunyamula ndi kuteteza zigawo za semiconductor, ndipo amathanso kusamutsa bwino kutentha ndi mphamvu. Kudzera mu chogwirira ndi mabulaketi atatu okhazikika pansi pa cholumikizira cha graphite, zigawo zambiri za semiconductor zitha kuyikidwa mu cholumikizira cha graphite kuti zigwirizane bwino ndi cholumikizira cha graphite, motero zimasamutsa bwino kutentha ndi mphamvu.

Kuphatikiza apo, chovindikira cha graphite chingagwiritsidwenso ntchito ngati chovindikira cha kutentha ndi magetsi choyenera. Chifukwa cha kutentha kwake kwakukulu komanso mphamvu yamagetsi, chovindikira cha graphite chimatha kuyendetsa kutentha ndi mphamvu kuchokera kunja kwa zida kupita ku zigawo za semiconductor mkati mwa chovindikira cha graphite, motero chimatenthetsa bwino zigawo za semiconductor ndikulamulira mphamvu yamagetsi.

Kuphatikiza apo, chophikira cha graphite chingathenso kugwira ntchito ngati chowongolera kutentha ndi magetsi abwino kwambiri, chomwe chingathe kusunga zinthu zambiri za semiconductor, zomwe zimathandiza kuti zipangizozi zigwire zinthu zambiri nthawi imodzi, motero zimathandiza kuti zipangizozi zigwire bwino ntchito.

Kodi kugwiritsa ntchito graphite crucible mumakampani ndi kotani?

Kukhazikika kwa kutentha kwambiri komanso kukhazikika kwa mankhwala kwa chofufumitsa cha graphite kumathandiza kuti chizitha kupirira kusungunuka kwa chitsulo kutentha kwambiri, zomwe zimapangitsa kuti zinthu zosungunuka zikhale bwino komanso zokhazikika. Chifukwa chake, chingagwiritsidwe ntchito pokonzekera ndi kusungunula zinthu zosiyanasiyana zachitsulo, monga mkuwa, aluminiyamu, zinki, ndi zina zotero. Kuphatikiza apo, chofufumitsa cha graphite chingagwiritsidwenso ntchito pokonzekera ndi kusungunula zinthu za alloy.

Kuphatikiza apo, zophimba za graphite zimakhalanso ndi kukana dzimbiri bwino. Graphite imakhala ndi kukana dzimbiri kwambiri ku zinthu zambiri zamakemikolo ndipo imatha kulimbana ndi kuwonongeka kwa zinthu zowononga monga ma acid, alkali, ndi zosungunulira. Chifukwa chake, zophimba za graphite nthawi zambiri zimagwiritsidwa ntchito kusunga, kusamalira, ndi kusanthula zinthu zowononga. Mwachitsanzo, mumakampani opanga mankhwala, zophimba za graphite zitha kugwiritsidwa ntchito potola zitsanzo, kusungunula zinthu, ndikusunga ma acidic reagents. Mu kapangidwe ka organic, zophimba za graphite zitha kugwiritsidwa ntchito pochiza zosungunulira ndi zoyambitsa, komanso njira yopangira makristalo ndi kuumitsa zinthu zachilengedwe.

Chidule

Kuwonjezera pa kugwiritsidwa ntchito kwake popanga zinthu za semiconductor, zinthu zoyambira za graphite zimathanso kugwira ntchito yofunika kwambiri pakupanga zitsulo, kuponyera, makina, chemistry ndi madera ena. Mwachitsanzo, mumakampani opanga zitsulo, zinthu zoyambira za graphite zitha kugwiritsidwa ntchito kusungunula ndi kuyeretsa zipangizo zachitsulo; mumakampani opanga zitsulo, zinthu zoyambira za graphite zitha kugwiritsidwa ntchito kusungunula zipangizo zachitsulo ndikupanga zinthu zosiyanasiyana zachitsulo; mumakampani opanga mankhwala, zinthu zoyambira za graphite zitha kugwiritsidwa ntchito ngati zoyezera kapena zotengera za machitidwe a mankhwala. Chifukwa chake, kufunika kwa zinthu zoyambira za graphite sikungowonekera m'magawo ogwiritsira ntchito, komanso pantchito yake yofunika kwambiri popanga mafakitale. Ndi chitukuko chopitilira cha sayansi ndi ukadaulo, mwayi wogwiritsa ntchito zinthu zoyambira za graphite udzakhala wokulirapo.
