acid resistant ceramic bricks

acid resistant ceramic brick's advantage: 1)acid resistance 99.8% 2)water absorption<0.5% 3)Not easy to be oxidized

Installation of acid resistant ceramic bricks:

 Using oxalic acid to wash the surface of concrete and tiles, make it neutralization of acid and alkali. Usually, we use colophony, araldite, acid-proof cement to install the tiles.

The slot between the tiles is usually 8 -10mm . It's better to make the slot thickness is same as the thickness as the tile thickness to prevent from chemical leakage.

 Using the oxalic acid to wash the surface of the floor after the installation.
