Kumvetsetsa Mfundo za Kutentha kwa Mayamwidwe a Graphite Silicon Carbide Crucibles

Zojambula za graphite silicon carbide cruciblesndi zigawo zikuluzikulu mu ntchito zosiyanasiyana kutentha kwambiri, kuphatikizapo zitsulo, ma laboratories mankhwala, ndi njira mafakitale. Ma crucibles awa ndi odziwika chifukwa cha mawonekedwe ake apadera amayamwidwe a kutentha, omwe ndi ofunikira kwambiri kuti azikhala okhazikika komanso ochita bwino m'mikhalidwe yovuta kwambiri. M'nkhaniyi, tikufufuza mfundo zazikuluzikulu zomwe zimayendetsa kutentha kwa ma graphite silicon carbide crucibles.

1. Kutentha Kwambiri Kwambiri

Chimodzi mwa zifukwa zazikulu zomwe ma graphite silicon carbide crucibles amachitira bwino pakuyamwa kutentha ndi mphamvu yawo yotentha. Makhalidwe amenewa amawathandiza kuti azitha kuyamwa mofulumira ndikusunga kutentha kwakukulu. Akakumana ndi kutentha kwambiri, ma crucibles amangotenga mphamvu kuchokera kumadera awo komanso amasunga kutentha kwambiri kwa nthawi yayitali. Kutha kupirira ndi kusunga kutentha kwakukulu kumawapangitsa kukhala ofunikira pakuyesa ndi njira zomwe zimafuna kutenthedwa ndi kutentha kwambiri.

2. Chemical Properties

Kuphatikiza pa mphamvu yamafuta, mankhwala a graphite silicon carbide crucibles amagwira ntchito yofunika kwambiri pakuyamwa kwawo kutentha. Pakutentha kwambiri, gawo la graphite la crucible limatha kuchitapo kanthu ndi okosijeni kupanga mpweya wa carbon dioxide. Izi zimatsagana ndi kutulutsa mphamvu, zomwe zimapangitsa kuti crucible itenthe kutentha. Kulumikizana pakati pa mankhwala azinthu ndi momwe chilengedwe chimakhalira kumapangitsa kuti mphamvu zake zizitha kutentha bwino.

3. Maluso a Adsorption

Ma graphite silicon carbide crucibles alinso ndi mphamvu zotsatsa, zomwe zimawapangitsa kukopa ndikusunga chinyezi ndi zonyansa zina zomwe zimawazungulira. Katundu wa adsorption uyu amapereka njira yowonjezera yolumikizira kutentha, kukulitsa mphamvu zonse zowongolera kutentha kwa crucible.

Mapeto

Njira yoyamwitsa kutentha kwa ma graphite silicon carbide crucibles ndi kuphatikizika kovuta kwa zinthu zawo zakuthupi ndi mawonekedwe amankhwala. Kutentha kwawo kwakukulu, chilengedwe chokhazikika cha mankhwala, ndi mphamvu zotsatsa pamodzi zimathandizira kuti athe kutenga bwino kutentha ndikukhalabe bata pansi pa kutentha kwakukulu. Makhalidwewa amapanga ma graphite silicon carbide crucibles kukhala chida chofunikira pakugwiritsa ntchito kutentha kwakukulu, kuwonetsetsa kulondola komanso kuchita bwino pamachitidwe omwe amafunikira kuwongolera kwambiri kutentha.
