Anti-acid tiles and bricks
Visits: 15
Anti-acid tiles and bricks are resistant to all acids except hydrofluoric acid at any concentration, as well as all oils, fats and solvents. These tiles are not resistant to strong alkalis in the long run, but they are resistant to alkalis falling on them. In other words, these tiles can not be used in tanks and pits that contain alkalis with high temperature and concentration, but on floor surfaces that are only exposed to alkali, the use of ceramic tiles is allowed.
These types of tiles, depending on the correct granulation structure of their ingredients and the appropriate baking temperature, have high mechanical strengths, especially desirable abrasion resistance.
The anti-acid tiles and bricks produced in this collection are in accordance with international standards and are in accordance with ASTM C-279 standard. These parts are designed and manufactured in simple and complex shapes and the shape and size of these parts can be changed according to need.
Although it is possible to make different dimensions, but the standard dimensions that are commonly produced and used in industrial projects are as follows: 230 * 114 * 60 and 230 * 114 * 30
Select the type of anti-acid tiles and bricks:
It is usually recommended not to use thin tiles with a thickness of less than 20 mm for anti-acid lining ceramics on floor surfaces in industrial units.
In case of normal heat loads, tiles with a thickness of more than 30 mm should be used.
In case of stronger thermal and mechanical loads, thick tiles with a thickness of about 60 mm (anti-acid bricks) should be used. If the retaining layer used under the tile is heat sensitive, the use of thick tiles is recommended.
How to make anti-acid tiles and bricks:
First, the concrete surfaces under the work should be inspected before starting the operation of the anti-acid tiling system. . All loose concrete surfaces, including the cement layer applied to the main concrete, as well as cement slurries and concrete mortar must be removed from the main concrete.
If old concrete floor surfaces are present, the condition of the concrete in terms of corrosion should be thoroughly examined. If the readings penetrate into the concrete, the corroded areas should be destroyed and the concrete should be poured again. Other areas should also be neutralized and washed. If there is oil on the surfaces, clean the operation.
Concrete or masonry surfaces must be completely dry when applying resin coatings. Apparent and surface dryness is not enough, but the applied concretes must have completely passed their drying period. If this is not observed due to the capillary nature, the remaining moisture will increase in the depth of the concrete and will cause the adhesion of the resin coating with the concrete to disappear. The moisture content of concrete should not be more than 4%.
How to arrange anti-acid tiles and bricks:
Regarding the type of tile arrangement, it is recommended to place the tiles in the direction of the length towards the exit paths and channels, or in other words, the longitudinal joints should be placed in the direction of the slope. In this way, corrosive liquids are transferred to the outlet paths more quickly
When tiling, the mortar is placed behind the tiles and installed on the surfaces. Mortars must be completely hollow and free of air and bubbles. The thickness of the installation mortar is 5 mm and up to 10 mm thickness is allowed if needed. Execution of more than this thickness causes shrinkage and at the same time is expensive.
