Borosilicate Foam Glass Lining Brick
Borosilicate Foam Glass Lining Brick
- Borosilicate foam glass, B203 containing, has good resistance to both acid and alkali, so it is a good protection layer to acid condensation produced from wet desulphurization.
- foam glassbrick reaches more than 1.5MPa, which significantly exceeds the requirement of chimney liner, in a way offers potential to reduce the cost of the chimney.
- Cellular Glassis coefficient is less than 0.058 w/m.k， and its service life is the same as the chimney itself.
