Gypsum-specific Polycarboxylate superplasticizer details

The new Polycarboxylate superplasticizer is a high-efficiency water-reducing agent mainly composed of polycarboxylic acid and its derivatives. It has excellent physical and chemical properties and plasticizing effect, and can effectively improve the fluidity and processing performance of concrete. At the same time, the new polycarboxylic acid-based water-reducing agent has good dispersion and penetration, which can reduce defects such as shrinkage, cracks, and deformation of concrete, and improve the strength and durability of concrete.

Polycarboxylate superplasticizer has a retarding effect on gypsum and reduces the strength of gypsum. At the same dosage, adding cement and calcium oxide to gypsum can improve the fluidity of gypsum. As the water-to-gypsum ratio decreases, the density of gypsum increases, and the strength also increases. At the same time, due to the reinforcing effect of cement hydration products on gypsum, the flexural and compressive strength of gypsum is increased.  As the amount of cement and calcium oxide increases, the fluidity of gypsum increases, and an appropriate amount of cement can significantly increase the strength of gypsum.

When using polycarboxylate ether water-reducing agent in gypsum, adding an appropriate amount of cement can not only increase the strength of the gypsum, but also achieve greater fluidity and have less impact on the setting time of the gypsum.

Function of special polycarboxylic acid high-efficiency water-reducing agent for gypsum
It can effectively improve the processing performance of building gypsum. Adding water reducing agent within a certain dosage range can reduce the stickiness and viscosity of building gypsum, making the gypsum slurry easier to apply and operate. At the same time, the water-reducing agent can also improve the flatness and smoothness of the gypsum surface and improve the aesthetics of the gypsum.

It can effectively improve the strength and durability of building gypsum. By optimizing the ratio of additives to gypsum and controlling factors such as the cement ratio and hydration time of gypsum, the compressive strength and tensile strength of gypsum can be significantly improved.  In addition, water reducing agents can make the plaster more dense and uniform, thereby improving its water resistance, frost resistance and durability.

The performance and quality of building gypsum can also be optimized. The voids in gypsum are small, evenly distributed, and the surface finish is high, making it more suitable for wall decoration and interior decoration. In addition, the water-reducing agent can also make the color of gypsum more uniform and the dosage more economical, thus having a positive impact on energy conservation, emission reduction and environmental protection.
