Application of polycarboxylic acid superplasticizer in refractories

(Application of polycarboxylic acid superplasticizer in refractories)

Basic action principle of superplasticizer

Superplasticizeris a chemical agent. Changing the chemical action ability of concrete and water can reduce the surface tension of the saturated paste of concrete and maintain the dispersion state between particles in concrete.

This can reduce concrete's viscosity and friction, increase its fluidity, and control its rheological properties.

In refractories, water reducer can play a similar role, make the dispersion state between different components of the material more uniform, and improve the comprehensive properties of the material.

Modification effect and advantages of polycarboxylic acid superplasticizer on refractories

Polycarboxylate superplasticizer is a superplasticizer. Compared with traditional sulfonate superplasticizers, polycarboxylate superplasticizer has the advantages of reducing water secretion, controlling expansion, improving crack resistance, accelerating hardening, and so on.

In refractories, the application of polycarboxylic acid superplasticizer can effectively improve the comprehensive properties of refractories, which is shown in the following aspects.

1. Reduce the amount of water and improve the processability of materials.

Polycarboxylic acid superplasticizer can effectively reduce the amount of cement needed for the material and improve its processability, ensuring its stability and quality during processing.

2. Improve crack resistance.

Polycarboxylic acid superplasticizer can reduce the material's cracking, greatly improving its crack resistance.

3. Improve high-temperature resistance. 

Polycarboxylic acid superplasticizer can accelerate the hardening process of the material and make it more compact, thus improving its high-temperature resistance.

Application and effect of polycarboxylic acid superplasticizer in different kinds of refractories1. Aluminosilicate refractory

In aluminosilicate refractories, the application of polycarboxylic acid superplasticizer can effectively improve the materials' comprehensive properties and greatly improve their crack resistance and high-temperature resistance.

2. Ceramic fiber thermal insulation material

In ceramic fiber thermal insulation materials, the application of polycarboxylic acid superplasticizer can accelerate the hardening process, improve the stability and processability of the material, and thus improve its comprehensive properties.

3. Silicon carbide refractory

In silicon carbide refractories, the application of a polycarboxylic acid superplasticizer can effectively reduce the water secretion rate and improve the materials' crack resistance and high-temperature resistance.

Conclusion

The application of polycarboxylate superplasticizers in refractories has obvious advantages and effects.

By adding the appropriate amount of polycarboxylic acid superplasticizer, the comprehensive properties of materials can be effectively improved, the quality and firmness of refractories can be improved, and the construction cost can be effectively reduced.
