Khoom Description

Cov ntaub ntawv refractory xa mus rau cov ntaub ntawv uas tuaj yeem tswj tau qee yam khoom siv thiab tshuaj lom neeg ruaj khov nyob rau hauv ib puag ncig hnyav xws li kub, acid, alkali, thiab corrosion. High alumina cement yog cov khoom siv refractory feem ntau.

High alumina cement feem ntau yog ua los ntawm siab -alumina bauxite thiab limestone calcined ntawm qhov kub thiab txias. Txij li thaum lub ntsiab tseem ceeb ntawm alumina bauxite yog Al2O3, siab alumina cement muaj cov ntsiab lus Al2O3 siab heev thiab muaj hluav taws kub zoo heev.
