Acid-resistant tile resistant to acidic environments and other corrosive chemical compounds for use in petrochemical, power plant and food industries, chemical corrosion-resistant tile or antacid tile produced by Pasargad Refractory Company, a fully vitreous tile with very low water absorption and dissolution in It is a low acid which is produced on the basis of mineral clay compounds and by pressing or extrusion method in the factory of this company. These products are produced with a thickness of 20-30 mm, of which a thickness of 25 mm is more common.
All quality tests of this product, in addition to the laboratory located in the quality control unit of the factory, are routinely performed in reputable laboratories. The compressive strength of these products is optimal (about 70 MPa) and its flexural strength is about 12 MPa. The acid solubility of this product is so low that the amount of acid solubility in 48 hours in sulfuric acid was 98% – less than 0.5%
This tile is used in environments that are exposed to a variety of acids (except HF). Also in areas where there is a need for mechanical strength, such as the floor of industrial warehouses where there is light vehicle traffic and forklifts. In acid and chemical ponds and floor and wall coverings of industrial halls in various industries, including petrochemical and chemical industries. Used in dairy and beverage factories, acid and galvanized sheet factories, as well as power plants.
To install and fasten this type of anti-acid tile. Definitely requires the use of anti-acid mortars. The company also produces some types of mortars domestically. The common size of this type of tile is 25 x 117 x 233 mm. The tile floor has grooves 3 mm thick for a stronger connection with the mortar below.
Important points of implementing anti-acid tiles:
Before running
If the concrete surface under the work is loose or has a depression, these parts should be filled with cement plaster. If the damage is severe and the acid has penetrated deep into the concrete surface, the concrete surface must be destroyed and the concrete must be applied again. Check the slopes. If the slope is not applied, it is better to apply it with cement plaster. The surface under the work must be dry and free of fat and oil.
Before execution, pay attention to the sealing of the structure and the minimum temperature required for installation
Membrane layer
Inside open tanks, pits and collection tanks, due to the presence of permanent corrosive substances, the use of a resin layer or a plastic sheet or a rubber layer as membranes is not enough and should be applied on it or ceramic or carbon tiles or tiles. Be.
There should not be a long time interval between the application time of the membranes and the application of the anti-acid tile and no mechanical load should be applied to it.
Anti-acid tile arrangement
In general, the grooves on anti-acid tiles have better adhesion due to the mechanical connection between the tile and the mortar. The maximum depth of the depression should not be more than 5 mm because it may create empty spaces under the tile, which is very dangerous and on the other hand, the consumption of mortar is higher.
The tiles are arranged in such a way that the longitudinal strap is in the direction of the floor slope. If the walls are not tiled, at least 10 cm from the wall should be tiled
First, cover the back of the tile with mortar, then install
The thickness of the executive mortar is between 5-10 miles
The mortar bond between the tiles is filled after grazing
The thickness of the tile strap is between 5-20 miles (better value is 5-8 miles). Tile joints are very important and are always subject to corrosion and damage
Tile fastening should be done a few days after installing the tile
Anti-acid mortar:
To make anti-acid tiles, you need anti-acid mortar or anti-acid adhesive. This company produces some types of anti-acid mortars. Depending on the environmental conditions and corrosive factors, the type of mortar is selected, the most important type of mortar needed to connect anti-acid tiles. Acid is a volatile mortar which is a type of synthetic resin mortar and is resistant to corrosion of sulfuric acid up to 60%. Also, in parts where there are stronger acids, silicate mortar should be used.
packing :
This product should be packed in a wooden pallet and plastic cover with a plastic strap. There is a cardboard sheet between the layers.
