Ceramic reinforcing agent refers to the material used for strengthening and plasticizing ceramic billet. The reinforcing agent is usually organic polymer. Common enhancers are modified starch, methyl cellulose, polyvinyl alcohol and acrylic polymers, sodium alginate, dextrin, extract, etc. Recently, there are new ceramic enhancers such as sodium polyacrylate compound, etc.

The strengthening effect of common ceramic enhancers is poor, and often requires a high amount of addition. However, when the addition amount is high, a series of problems often occur; For example, in the slurry stage, the higher content of reinforcing agent will lead to the thixotropy of the slurry and affect the fluidity of the slurry; In the billet forming stage, often cause easy to stick mold, resulting in surface defects; In the firing stage, defects such as black hearts can be caused.

On the other hand, clay is one of the main raw materials in the production of building ceramics. In addition to providing the ingredients needed for building ceramics, it is more important to provide plasticity to give the forming performance of the billet. However, clay will increase the firing loss of the formula, which not only restricts the shortening of the firing cycle, but also increases the emission of flue gas, which brings greater pressure to the environmental protection production of building ceramics. Clay mainly exists in farmland, fish ponds and hilly and low-lying areas. It is difficult to regenerate resources, and a large amount of mining has caused damage to the environment. Therefore, replacing clay is of great significance for ceramic production.

As a ceramic reinforcing agent, sodium lignosulfonate has a good effect and a small amount, which does not affect the ceramic production process. It is widely used all over the world.
