Calcined Alumina

Alpha calcined alumina yog cov khoom tom qab reactive alumina hmoov yog calcined nyob rau hauv siab kub. Lub ntsiab theem yog -Al₂O₃.

Alpha Calcined alumina tuaj yeem yog 1 μm tom qab sib tsoo, nrog rau kev ua haujlwm zoo. Nws yog dav siv raws li ultra nplua hmoov rau monolithic refractories kom nce lub liquidity ntawm lub castable. Nrog Alpha calcined alumina ntxiv, refractory blocks kuj muaj zog dua, zoo corrosion kuj thiab zoo thermal kuj.

Thaum lub sij hawm sintering txheej txheem los ntawm Alumina hmoov rau calcined alumina, lub -Al₂O₃pib tig mus rau -Al₂O₃theem txij li 1000 degree, thiab nws xav tau sijhawm kom tau txais Alpha Calcined alumina tag nrho. Muaj qhov ntim loj txo thaum lub sijhawm ua haujlwm no. Yog li alumina hmoov tsis tshua siv ncaj qha los ua raw khoom rau cov khoom siv refractory. Calcined alumina hmoov muaj kev ua haujlwm ruaj khov tom qab cov txheej txheem sintering no, yog li feem ntau nws tau siv los ntawm alumina hmoov.

Nyob rau hauv xyoo tas los no, vim muaj kev cuam tshuam tsis zoo rau castable los ntawm CaO (nqa los ntawm siab alumina cement), ntau thiab ntau lub tuam txhab tsim ultra- cement castable tsawg lossis tsis muaj cement castable. Nyob rau hauv xws li cov khoom, Alpha alumina hmoov yog ntxiv los ua tus neeg sawv cev es tsis txhob siab alumina cement. Kev kho yog yooj yim dua, thiab liquidity yog zoo dua.

Cov ntaub ntawv refractory xa mus rau inorganic non{0}}cov ntaub ntawv hlau nrog refractoriness tshaj 1580℃.

Refractory raw khoom yog cov khoom siv raw siv los tsim cov cib refractory thiab monolithic refractories.

Hom: Muaj cov khoom sib xyaw ua ke, cov khoom sib txuas, cov khoom ntxiv, cov tshuaj tiv thaiv -oxidants thiab lwm yam.

Rau cov kev siv sib txawv, muaj cov ntaub ntawv nyoos thiab cov khoom siv hluav taws xob hnyav

Ntev Keter muab cov khoom siv dav dav, suav nrog alumina bauxite siab, Kaolin flint av nplaum, tabular alumina, alumina hmoov, xim av fused alumina, dawb fused alumina, magnesia spinel, mullite thiab lwm yam.
