Raw materials for the production process of kaolin tiles, feldspar, bentonite are used as the main raw materials of the body in tiles and ceramics, and the main of these materials are bentonites, because bentonites increase the resistance of the body of tiles and ceramics, which is also It goes back to their granulation type.
Amin Business Group is a supplier of raw materials for the tile and ceramic industry!
Type and specifications of minerals used in the tile industry:
1. Elite
The three-layer soil has potassium, which leads to low water absorption. The greener the color, the betterBecause it has more K.
Properties:
1: Low hardness
2: High baking strength
3: Stability in dimensions
4: Increasing the efficiency of balmil and press
5: Normal expansion after pressing
6: Low melting point
2. Bentonite (Montmorey Lonite)Pure bentonite is called montmorillonite. Its main mineral is montmorillonite. Its structure is similar to illite.
Properties in the body:
1: Thickness expansion after pressing
2: High raw and dry strength but low curing strength
3: High contraction
4: High water absorption
5: Strength after pressingIts use is more on the wall than on the floor.
3. talkAqueous magnesium silicate
Properties:
1: the softest substance in Mohs’ table; Difficulty 1
2: It has a greasy or soapy touch.
3: Three-layer building
4: High expansion after cooking and drying
5: Resistance to thermal shock
6: dimensional stability
7: Improving the quality of the body surface
8: Help to dry the glaze
9: The glaze applied on it creates a smooth surface after baking.
4. PyrophylliteThree-layer clay.
It is mostly used in floor tiles.
Properties:
1: Low plasticity
2: Low water absorption
3: Normal expansion after pressing
4: Low raw and dry strength
5: Expansion after drying is high.
6: After baking, it shows a very high expansion at a temperature of 1020 degrees.
5. Types of carbonates and double carbonatesThey come out at temperatures lower than 900-800 degrees. If we do not give time for 2Co to leave, defects such as swelling and darkening of the glaze will be created in the body. After this, these ingredients should not be used in quick cooking because they will not come out quickly.Its advantages (2Co):
1: High baking strength
2: Preventing the lunar eclipse defect
3: preventing thermal expansion
4: dimensional stability
5: High water absorption
6. destructionCalcium silicate can be used instead of carbonate.
Properties:
1: High baking strength: the main reason is having needle crystals.
2: Low thermal expansion coefficient
3: Low raw and dry strength but high curing strength
4: no dry shrinkage at all; which is good for floor tiles.
5: At a temperature of 1020 degrees, its baking shrinkage is 0.3%. In Iran, this material is used for the body, but it is used for the glaze because it is used in the glaze of the tiles The wall and floor no longer boil due to the opaqueness of calcium carbonate.
7. chlorite
Due to the dark color after cooking, it is mostly used in single-baked red bodies.
