Kunzwisisa Musiyano pakati peClay Graphite Crucibles uye Graphite Silicon Carbide Crucibles

Paunenge uchiita kuyedza-kupisa kwemakemikari kuyedza kana maindasitiri mashandisirwo, kusarudzwa kwezvinhu zvecrucible kunoita basa rakakosha mukuona kubudirira uye kuchengetedzeka kwemaitiro. Mhando mbiri dzinowanzo shandiswa dzemacruciblesivhu graphite cruciblesuyegraphite silicon carbide crucibles. Kunzwisisa kuumbwa kwayo kwezvinhu, tembiricha yerefractory, makemikari inertness, uye thermal conductivity kwakakosha pakuita sarudzo ine ruzivo kana uchisarudza crucible yakakodzera kune chaiyo murabhoritari kana maindasitiri zvinodiwa.

material ingredient:
Clay graphite crucible inonyanya kuumbwa negraphite, ivhu uye imwe huwandu hwemafuta, uye inozivikanwa nekusagadzikana kwayo kwemakemikari. Kune rimwe divi, graphite silicon carbide crucible inogadzirwa nesilicon carbide poda uye imwe isingawanzo pasi oxides, uye ine hunhu hwekupisa tembiricha kuramba, yakanakisa kupisa kwekuvhunduka, uye yakakwira makemikari inertness.

Kupisa kupisa kwemoto:
Tembiricha yekuramba yevhu graphite crucibles kazhinji inosvika 1200 ° C, nepo graphite silicon carbide crucibles inogona kumira tembiricha iri pamusoro pe1500 ° C. Izvi zvinoita kuti graphite silicon carbide crucibles inyatsokodzera zvikumbiro zvinoda kupisa kwakanyanya mukuyedza kwemakemikari uye maindasitiri maitiro.

Kemikari inert:
Mhando mbiri dzemacrucibles dzinoratidza dhigirii remakemikari inertness, inoramba yakagadzikana mune yakawanda acid, alkali, uye munyu mhinduro uye inoshingirira mukuora. Nekudaro, chikamu chevhu muvhu graphite crucibles chinoita kuti zvive nyore kutora trace elements uye tsvina zvichienzaniswa negraphite silicon carbide crucibles.

Thermal Conductivity:
Graphite ine high thermal conductivity uye inogona kubvisa kupisa nekukurumidza. Zvisinei, nekuda kwechimiro chakasununguka chevhu graphite crucible, mavara madema anowanzoonekwa pamusoro payo uye anoda kugara achicheneswa. Kusiyana neizvi, graphite silicon carbide crucibles ine yakaderera yekupisa conductivity uye haizosiyi mavara pamusoro. Mukuwedzera, kuoma kwavo kwakakwirira kunodzivirira kupfeka uye deformation.

Sarudza crucible chaiyo:
Pakusarudza kemikari laboratory crucible, zvinodiwa chaizvo zvinofanirwa kutariswa. Clay graphite crucibles akakodzera kune akajairwa kemisitiri kuyedza, nepo graphite silicon carbide crucibles yakanakira kuyedza inoda yakanyanya tembiricha uye zvakanyanya kudiwa mamiriro. Zvakakosha kunyatsotevera mirairo yekushandiswa kudzivirira kukundikana kwekuedza nekuda kwekushanda kusina kunaka.

Muchidimbu, kunzwisisa mutsauko uripo pakati pevhu graphite crucibles uye graphite silicon carbide crucibles yakakosha pakusarudza yakanyanya kufanira crucible kune chaiyo rabhoritari kana indasitiri yekushandisa. Nekutarisa zvinhu zvakaita serefractory tembiricha, makemikari inertness uye kupisa kwekushisa, vaongorori nenyanzvi dzemaindasitiri vanogona kuita sarudzo dzine ruzivo kuti ive nechokwadi chekubudirira uye kuchengetedzeka kwekuedza uye maitiro.
