Corundum Cib

Cov khoom lag luam zoo: siab zog, tiv taus kub, tiv taus xeb, thiab ruaj khov tshuaj zoo.

khoom piav qhia

High-purity corundum bricks siv tabular corundum thiab fused corundum ua cov ntaub ntawv tseem ceeb, dhau los ntawm kev tshawb fawb thiab qib tsim nyog, nrog rau kev ua tau zoo tshaj plaws ntxiv, ua kom siab siab, ua kom sov kub, thiab cov khoom siv hluav taws xob tau ua los ntawm lub zog siab thiab kub tsis kam Corrosion kuj thiab tshuaj lom neeg ruaj khov.
