In the production of ceramic wall and floor tiles, adding ceramic body reinforcing agent is an effective measure to improve the strength of the body, especially for porcelain tiles with large barren materials, its effect is more obvious. Today, when high-quality clay resources are increasingly scarce, the role of green body enhancers is becoming more and more obvious.
Features: The new generation of carboxymethyl cellulose CMC is a new type of polymer body reinforcing agent, its molecular distance is relatively large, and its molecular chain is easy to move, so it will not thicken the ceramic slurry. When the slurry is spray-dried, its The molecular chains are exchanged with each other to form a network structure, and the green body powder enters the network structure and is bonded together, which acts as a skeleton and significantly improves the strength of the green body. It fundamentally solves the defects of the currently commonly used lignin-based green body reinforcing agents—seriously affecting the fluidity of mud and being sensitive to drying temperature. Note: The performance test of this product should make a small sample and measure its actual strength after drying, instead of measuring its viscosity in aqueous solution like traditional methyl to measure its strengthening effect.
1. Performance
The appearance of this product is powdery, soluble in water, non-toxic and tasteless, it will absorb moisture when stored in the air, but it will not affect its performance. Good dispersibility, less dosage, remarkable reinforcing effect, especially can significantly improve the strength of the green body before drying, reduce the damage of the green body, and will not form black centers in the tiles. When the temperature reaches 400-6000 degrees, the reinforcing agent will be carbonized and burned, which has no adverse effect on the final performance.
Adding carboxymethyl cellulose CMC for the base has no adverse effect on the fluidity of the mud, no need to change the original production process, and the operation is simple and convenient. Transfer, etc.), you can increase the amount of carboxymethyl cellulose CMC used in the billet, which has little effect on the fluidity of the mud.
2. How to use:
1. The addition amount of carboxymethyl cellulose CMC for the new generation of ceramic blanks is generally 0.01-0.18% (relative to the ball mill dry material), that is, 0.1-1.8 kg of carboxymethyl cellulose CMC for ceramic blanks per ton of dry material, Green and dry body strength can be increased by more than 60%. The actual amount added can be determined by the user according to the needs of the product.
2. Put it into the ball mill together with the powder for ball milling. It can also be added in the mud pool.
