Acid resistant bricks
    They are used as flooringlining in many kinds of chemical reactors, towers (including drying towers, absorption towers, etc.), and tanks of acids & other chemicals in chemical factories, fertilizer factories, sulphuric acid factories, iron & steel factories, etc. They are used as lining of antiseptic pools and ditches.
Installation:
    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.
