Zirconia Crucible Description
Zirconia lub siab txhua yam khoom, tshuaj inertness, high-temperature stability, corrosion resistance, thiab high quality tau muab cov ceramic steel rau ntawm radar nyob rau hauv ntau industries thiab daim ntawv thov. Ntau yam khoom ntawm niaj hnub no, xws li refractory mus rau cov khoom kho mob, pigments, electronics, coatings, thiab ceramics, tau raws li zirconia vim nws superior yam ntxwv thiab zoo piv rau lwm yam ntaub ntawv.
Vim nws cov thermal tsis kam, zirconium dioxide yog siv los ua cov khoom siv hauv crucibles, furnaces, thiab lwm qhov chaw kub kub. Tsis tas li ntawd, zirconium dioxide boosts fireproof zog ntawm ceramics.
Zirconia cov khoom tuaj yeem tiv taus qhov kub siab txog 2100 degree. Nws yog cov khoom siv zoo tshaj plaws rau melting ntawm precious hlau thiab super-alloys uas muaj melting point siab tshaj 1800 degree. Zirconia Crucibles muaj nyob rau hauv ntau qhov ntau thiab tsawg.
Zirconia crucibles yog cov khoom zoo heev thiab cov ntaub ntawv insulating. Lawv muaj cov yaj huv si ntawm qhov kub siab tshaj 1900 degree thiab siab dua thiab tau tsim tshwj xeeb rau melting superalloys thiab cov hlau muaj txiaj ntsig. Lawv kuj muaj cov tshuaj zoo heev inertness, superior thermal shock tsis kam mus rau qhov kub thiab txias mus txog 2200 degree, thiab zoo corrosion kuj rau acids thiab alkalis.
Cov khoom ntawm Zirconia
● High mechanical resistance
● Kub kub tsis kam thiab nthuav dav
● Tsawg thermal conductivity
● Tsawg thermal conductivity

Cov neeg siv phau ntawv qhia rau Zirconia khoom
● Zirconia cov khoom tsis muaj zog. Thov ua tib zoo saib xyuas lawv thiab tsis txhob sib tsoo thaum lub sij hawm unpacking, tsheb thauj mus los, tuav thiab tu.
● Tshawb xyuas seb puas muaj micro-cracks ua ntej siv cov khoom zirconia. Cov khoom siv nrog micro-cracks yuav tsum tsis txhob siv.
● Tsis txhob thauj cov ntaub ntawv ntau dhau hauv zirconia crucibles, uas tuaj yeem ua rau kom muaj cua sov tsis sib xws.
● Tus nqi qis qis thiab qhov ntsuas cua txias tau pom zoo kom txo qis thermal shock ntawm crucibles. Thaum nce qhov kub thiab txias, kev saib xyuas tshwj xeeb yuav tsum tau them rau ob lub sijhawm ntsuas kub: tsis tshaj 3 degree / MIN thaum lub sijhawm 100 degree - 300 degree thiab 1050 degree - 1200 degree . Tus nqi tuaj yeem nrawm dua hauv lwm qhov ntsuas kub, tab sis nws raug pom zoo kom tsawg dua 5 degree / MIN.
● Txhawm rau nqa lub crucible ncaj qha tawm ntawm qhov cub thaum kub kub yuav ua rau tawg. Yog tias ua tau, tshem nws tawm thaum qhov kub thiab txias qis dua 100 degree.
● Zirconia crucibles yuav tsum tsis txhob muab cua sov los ntawm lub teeb lossis lub cub tawg uas tswj tsis tau qhov kub thiab txias hloov pauv. Cov cua kub tsis sib xws tuaj yeem ua rau tawg.
● Nws raug nquahu kom muab qee cov hmoov zirconia (ib ncig ntawm 100mesh) nruab nrab ntawm lub hauv qab ntawm lub crucible thiab kev txhawb nqa ntawm crucible kom ua tiav qhov sib xws hauv thermal expansion coefficient.
● Yog hais tias lub crucible yog siv nyob rau hauv induction rauv, lub crucible yuav tsum tau surrounded los ntawm zirconia hmoov.
