Zirconia yog ib tug dawb hnyav amorphous hmoov los yog monoclinic siv lead ua, odorless, tasteless, yuav luag insoluble nyob rau hauv dej.Lub melting point yog hais txog 2700 ℃, nrog siab melting point thiab boiling point, hardness thiab lub zog, nyob rau hauv ib txwm kub raws li ib tug insulator, thiab kub kub muaj zoo heev zog xws li hluav taws xob conductivity.Tsis tas li ntawd, cov khoom siv tshuaj lom neeg ntawm zirconia yog qhov ruaj khov heev, tsis muaj dej, tsis muaj dej, hydrochloric acid thiab dilute sulfuric acid, muaj cov thermochemical stability, kub conductivity thiab kub kub lub zog thiab toughness, tib lub sij hawm muaj zoo mechanical, thermal, hluav taws xob, optical zog.
Zirconia txheej yog npaj los ntawm plasma txau, uas yog ib qho ntawm cov txheej txheem ceramic.Plasma spraying tshuab siv cov plasma arc uas tau tsav los ntawm cov khoom siv hluav taws xob ncaj qha los ntawm cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov khoom siv hluav taws xob, cov hlau, thiab lwm yam khoom siv rau molten lossis semi-molten lub xeev, thiab txau ntawm kev kub ceev mus rau saum npoo ntawm pretreated workpiece los tsim ib tug ruaj khov adhesion nto. txheej.Plasma txau los npaj zirconia txheej, nws cov yam ntxwv tseem ceeb yog raws li hauv qab no:
Muaj peev xwm;
1, kub tsis kam: zirconia melting point yog hais txog 2700 ℃, feem ntau siv nyob rau hauv cov ntaub ntawv refractory, yog li zirconia txheej muaj zoo kub kuj.
Muaj peev xwm;
2, hnav tsis kam: zirconia ceramics muaj zog dua thiab zoo dua hnav tsis kam, nws Mohs hardness yog li 8.5, nrog zoo hnav tsis kam;
3.Thermal barrier txheej: Daim ntawv thov ntawm plasma spraying zirconia thermal barrier txheej ntawm cov roj cav tau ua tiav zoo.Rau qee qhov, nws tau raug siv nyob rau hauv cov turbine ib feem ntawm cov roj turbines, uas tuaj yeem txhim kho qhov ua tau zoo ntawm cov khoom kub-kub.
Stainless hlau hlau mesh nrog Zirconia txheej yog dav siv nyob rau hauv kub kub ua hauj lwm ib puag ncig.Cov txheej txheem ib txwm muaj 60mesh / 0.15mm thiab 30mesh / 0.25mm.Peb tuaj yeem ua cov txheej txheem ntawm ob sab.Cov khoom siv no kuj tuaj yeem ua rau txheej txheej ntawm Nickel hlau mesh.High purity zirconia txheej tuaj yeem muab cov txheej txheem kub kub ua haujlwm. , corrosion kuj rau ntau yam ntaub ntawv workpiece, tshwj xeeb tshaj yog nrog txhuas, molybdenum, platinum, rhodium thiab titanium noCov ntaub ntawv hlau sib txuas ruaj khov dua.Nws yog qhov tshwj xeeb tshaj yog tsim rau txheej txheej ntawm cov cua sov ntawm lub qhov cub kub, uas tuaj yeem ua rau nws lub neej ntev.
