Kusiyana pakati pa graphite silicon carbide ndi dongo graphite crucibles

Zojambula za graphite silicon carbide cruciblesndi dongo graphite crucibles awiri zotengera labotale wamba amene ali ndi kusiyana kwakukulu mu zipangizo, katundu, ndi ntchito.

Zofunika:

graphite silicon carbide crucible: Wopangidwa ndi graphite silicon carbide zakuthupi, ali ndi kukhazikika kwa kutentha kwambiri, kukana kwa dzimbiri komanso matenthedwe abwino amafuta.
Dongo la graphite crucible: nthawi zambiri limapangidwa ndi dongo losakanizika ndi graphite, lokhala ndi ma graphite otsika, makamaka pogwiritsa ntchito dongo ngati maziko, ndipo graphite imawonjezedwa makamaka kuti ipititse patsogolo kutentha kwake.
Kukana kutentha:

Graphite silicon carbide crucible: Imatha kupirira kutentha kwambiri ndipo imatha kugwiritsidwa ntchito pa kutentha kwa 1500 ° C mpaka 2000 ° C kapena kupitilira apo.
Clay graphite crucible: Kutentha kwa kutentha kumakhala kochepa, ndipo kutentha komwe kumagwiritsidwa ntchito ndi 800 ° C mpaka 1000 ° C. Kupitilira kutentha kumeneku kumatha kuwononga mosavuta kapena kupindika kwa crucible.
Kulimbana ndi corrosion:

Graphite silicon carbide crucible: Ili ndi kukana kwa dzimbiri ndipo imatha kukana kukokoloka kwa mankhwala monga ma acid ndi alkalis.
Clay Graphite Crucible: Chifukwa cha dongo lake lambiri poyerekeza ndi graphite silicon carbide, ikhoza kukhala yosagonjetsedwa ndi mankhwala ena owononga kwambiri.
Thermal Conductivity:

Graphite silicon carbide crucible: Ili ndi matenthedwe abwino otenthetsera ndipo imatha kusamutsa kutentha kwachitsanzo mwachangu komanso mofanana.
Clay graphite crucible: Kutentha kwake kumatha kukhala koyipa pang'ono kuposa graphite silicon carbide crucible.
Mtengo ndi kugwiritsa ntchito:

Graphite silicon carbide crucible: Nthawi zambiri okwera mtengo, koma oyenera kuyesa ndi ntchito zomwe zimafuna kutentha kwambiri komanso kukana dzimbiri.
Clay graphite crucible: Mtengo wake ndi wocheperako, woyenerera ku labotale wamba, nthawi zomwe kutentha sikuli kokwera, kapena komwe kukana kwa dzimbiri sikuli kokhwima kwambiri.
Mwachidule, graphite silicon carbide crucibles ndi dongo graphite crucibles ali ndi kusiyana kwakukulu kwa zinthu, kutentha kukana, kukana dzimbiri, matenthedwe conductivity, etc. Kusankha mtundu wa crucible ntchito kuyenera kukhazikitsidwa pa zofunikira zoyesera ndi zofunikira. Mutha kutifunsa ndipo tidzakupatsirani ntchito zamaluso.
