I-silicon carbide crucible ekwazi ukumelana nobushushu obuphezulu kunye ne-thermal conductivity elungileyo

Ubushushu obuphezulu obuxhathisa isilicon carbide crucible with good conductivity thermal Image Featured

Inkcazelo emfutshane:

I-silicon carbide crucible yenziwe ngamasuntswana e-silicon carbide acocekileyo. I-silicon carbide ine-refractoriness ephezulu kakhulu kunye nokuchasana kakuhle kwe-oxidation, kwaye inokugcina iimpawu zayo zokuqala zomzimba kunye neekhemikhali kumaqondo okushisa aphezulu ngaphezu kwe-2000 ° C. I-silicon carbide crucible nayo ine-conductivity ephezulu ye-thermal kunye nokuzinza okulungileyo kwe-thermal, enokudlulisa ngokufanelekileyo ubushushu kunye nokuthintela isinyithi esityhidiweyo kwi-crucible evela ekushiseni.

Iinkcukacha zeMveliso

Iithegi zeMveliso

I-silicon carbide crucible yethu yenziwe ngokucofa okuphezulu kwe-isostatic kwaye inokuqhuba kakuhle kwe-thermal kunye nokumelana nobushushu obuphezulu. Kwinkqubo yokusetyenziswa kobushushu obuphezulu, i-coefficient yokwandiswa kwe-thermal incinci, kwaye inobunzima obuthile bokumelana nokufudumala kunye nokupholisa ngokukhawuleza. Inokumelana ne-corrosion eyomeleleyo kwisisombululo se-asidi kunye ne-alkali kunye nokuzinza okuhle kakhulu kweekhemikhali. Imodeli ethile ingenziwa ngokwezifiso ngokuzoba kunye nesampuli, kwaye izinto eziphathekayo ziyigraphite yasekhaya kunye negraphite ethunyelwa ngaphandle ukuhlangabezana neemfuno ezahlukeneyo zabathengi.

Iimpawu ze-silicon carbide crucible ziyaziswa

I-silicon carbide crucible yi-silicon carbide material, izinto zegraphite ezenziwe ngefomula yesayensi, yahlukile kwizinto eziqhelekileyo, xa ubushushu bonyusa i-silicon carbide crucible kungekuphela nje ukuthambisa okungaguqukiyo, amandla kodwa kwanda, kwii-degrees ezingama-2500, amandla okuqina kodwa aphindwe kabini.

I-1, itekhnoloji ephucukileyo: ukusetyenziswa kwendlela yokubumba i-isostatic ebandayo yehlabathi ebandayo yokwenza i-crucible, isotropy yemveliso ilungile, ingxinano ephezulu kunye namandla, ingxinano efanayo, akukho ziphene.

I-2, ukuxhathisa okulungileyo kwe-oxidation, qwalasela ngokupheleleyo uyilo lwefomula yokuthintela i-oxidation ye-graphite ngexesha lokusetyenziswa.

I-3, umaleko we-glaze oyingqayizivele: umphezulu we-crucible uneempawu ezininzi ze-glaze layer, ezidityaniswa nezinto ezixineneyo zokwenza izinto, ziphucula kakhulu ukuxhathisa kwe-corrosion yemveliso, ukwandisa ubomi benkonzo ye-crucible.

I-4, i-conductivity ephezulu ye-thermal: ukusetyenziswa kwezinto ze-graphite zendalo, indlela yokubumba i-isostatic, ukuveliswa kodonga lwe-crucible kuncinci, ukuhanjiswa kwe-thermal ngokukhawuleza.

I-5, ukugcinwa kwamandla okubalulekileyo: i-crucible eyenziwe ngezinto ezisebenzayo ze-thermal conductivity inokugcina amandla amaninzi kubasebenzisi kwinkqubo yokusetyenziswa.

I-Ningbo VET Energy Technology Co., Ltd (i-Miami Advanced Material Technology Co., LTD）lishishini lobugcisa obuphezulu obugxile kwimveliso kunye nokuthengiswa kwezinto eziphezulu eziphezulu, izixhobo kunye neteknoloji yokugubungela igraphite, i-silicon carbide, i-ceramics, unyango lomphezulu kunye nokunye. Iimveliso zisetyenziswa ngokubanzi kwi-photovoltaic, semiconductor, amandla amatsha, isinyithi, njl.

Ukutyhubela iminyaka, ipasile i-ISO 9001:2015 inkqubo yolawulo lomgangatho wamazwe ngamazwe, siqokelele iqela lamava kunye neetalente zeshishini elitsha kunye namaqela e-R & D, kwaye sinamava atyebileyo asebenzayo kuyilo lwemveliso kunye nezicelo zobunjineli.

Ngobuchule be-R & D obuvela kwizinto eziphambili zokuphelisa iimveliso zesicelo, undoqo kunye nobuchwephesha obuphambili bamalungelo azimeleyo epropathi enomgangatho ophezulu wokuqonda aphumeze inani lezinto ezintsha zenzululwazi nezobuchwepheshe. Ngenxa yomgangatho wemveliso ozinzile, isikimu soyilo esinexabiso eliphezulu kunye nenkonzo ekumgangatho ophezulu emva kokuthengisa, siphumelele ukuqondwa kunye nokuthenjwa kubathengi bethu.
