Alumina Tube yog dab tsi?

Q1: Dab tsi yog alumina raj?
A1: Alumina raj yog cov khoom siv tubular ua los ntawm txhuas oxide. Alumina yog ib qho inorganic compound nrog cov tshuaj formula Al2O3. Nws muaj cov khoom zoo xws li siab hardness, hnav tsis kam, thiab corrosion kuj. Nws yog feem ntau siv los tsim ntau yam khoom uas muaj kev hnav tsis kam, kub tsis kam, rwb thaiv tsev thiab lwm yam yuav tsum tau ua.
Q2: Dab tsi yog cov yam ntxwv ntawm alumina raj?
A2: Kev kub siab ua haujlwm: Aluminium oxide raj muaj qhov kub thiab txias tsis kam thiab tuaj yeem tswj kev ruaj ntseg thiab lub zog hauv qhov kub thiab txias. Feem ntau nws tuaj yeem tiv taus kub txog li ob peb txhiab degrees Celsius.
Hnav tsis kam: Aluminium oxide yeeb nkab muaj qhov tawv tawv heev thiab hnav tsis kam, thiab tuaj yeem tswj kev ruaj ntseg hauv kev sib txhuam siab thiab hnav ib puag ncig. Yog li ntawd, nws feem ntau yog siv los tsim cov khoom siv hnav-tiv taus lossis ua cov yeeb nkab hauv ob sab phlu.
Corrosion tsis kam: Alumina kav dej muaj zog tiv thaiv cov tshuaj xws li acids thiab alkalis, thiab tuaj yeem siv tau ruaj khov hauv corrosive media rau lub sijhawm ntev. Yog li ntawd, lawv feem ntau siv rau hauv cov kav dej tshuaj thiab lwm yam kev lag luam.
Rwb thaiv tsev: Alumina yog cov khoom siv insulating zoo, yog li cov raj alumina muaj cov khoom insulating zoo heev thiab feem ntau siv hauv kev lag luam fais fab raws li cov khoom siv hluav taws xob.
Chemical stability: Alumina tubes muaj tshuaj ruaj khov zoo ntawm chav tsev kub thiab tsis yooj yim corroded los ntawm cov tshuaj lom neeg. Yog li ntawd, lawv tau siv dav hauv kev lag luam tshuaj, tshuaj thiab lwm yam haujlwm.
Mechanical zog: Aluminium oxide yeeb nkab muaj lub zog txhua yam thiab nruj, tuaj yeem tiv taus qee qhov sab nraud thiab kev thauj khoom, thiab feem ntau siv los nqa thiab thauj khoom.
Cov khoom siv kho qhov muag: Aluminium oxide raj muaj qhov pom tseeb thiab lub teeb pom kev zoo, yog li lawv tau siv rau hauv qee qhov khoom siv kho qhov muag thiab cov khoom siv kho qhov muag.
