Khoom Taw Qhia
Lub hauv paus muaj pes tsawg leeg ntawm alumina weldable phaj yog alumina ceramic khoom, yog li ntawd, alumina weldable phaj yog ib qho tseem ceeb daim ntawv thov ntawm alumina ceramic cov ntaub ntawv. Nws muaj qhov tshwj xeeb hollow tsim, uas ua kom lub zog thiab ruaj khov thaum txhim kho hnav tsis kam ntawm cov ntaub ntawv ceramic kom ua tiav kev tiv thaiv zoo dua.
Yam ntxwv
1. Kev tsim tshwj xeeb hollow: Lub ntsiab tseem ceeb ntawm alumina weldable phaj yog ib qho ntawm cov qhov, uas txo qhov hnyav ntawm liner, txo cov khoom siv, thiab txhim kho qhov hnav tsis kam ntawm cov khoom siv.
2. High hardness thiab lub zog: Aluminium oxide yog ib qho nyuaj heev thiab hnav-resistant khoom nrog siab hardness thiab lub zog, thiab muaj peev xwm tiv taus hnyav siv ib puag ncig thiab kev ua haujlwm.
3. Kev tiv thaiv corrosion zoo heev: Txawm tias nyob rau hauv ib puag ncig ua haujlwm hnyav, cov khoom siv alumina ceramic tuaj yeem tiv taus corrosion thiab corrosion intrusion, tswj qhov zoo ntawm qhov zoo thiab kev ua tau zoo.
Daim ntawv thov
Alumina weldable phaj yog dav siv nyob rau hauv ntau yam khoom siv kho tshuab thiab kev lag luam, thiab lawv cov kev siv tseem ceeb yog raws li hauv qab no.
1. Metallurgical teb: Kub kub, siab siab thiab hnav yuav tshwm sim thaum lub sij hawm casting thiab dov txheej txheem, tab sis alumina weldable phaj tuaj yeem tiv taus qhov ntsuas kub, siab siab thiab hnav nyob rau hauv qhov chaw no, kom ntseeg tau tias siv cov khoom siv ib txwm muaj.
2. Kev siv hluav taws xob hluav taws xob: Hauv thaj chaw hluav taws xob xws li thee, roj av, thiab hluav taws xob nuclear, alumina weldable phaj liners tuaj yeem tiv thaiv cov cuab yeej los ntawm kev puas tsuaj vim qhov kub thiab txias, siab siab, thiab hnav hauv cov khoom siv.
3. Kev lag luam tshuaj: Hnav-resistant alumina weldable phaj tuaj yeem siv rau hauv kev tsim cov tshuaj tiv thaiv reactors thiab lwm yam khoom siv los ntawm hnav thiab corrosion.
Ua tib zoo saib xyuas kom tsis tu ncua thiab hloov kho thaum siv kom tsis txhob txo lub neej ntawm cov khoom siv thiab txo qhov hnav-tiv taus vim liner puas.
