Modified starch of Gypsum board
Product Introduction of Modified Starch Of Gypsum Board
In the production process of gypsum boards, starch, as a crucial additive, plays a vital role in determining product quality. Our specialized starch for gypsum board production is a high - quality product meticulously developed according to the characteristics of gypsum board production processes. With its outstanding performance and stable quality, it provides reliable production guarantees for gypsum board manufacturers.
Main function of Modified starch:
Starch is a kind of natural Polysaccharide, which plays an important role in the production of Gypsum board.
1. Increase the adhesion and toughness of Gypsum board: The viscosity and adhesion of starch can make the Gypsum board particales and fibers better combined, thus greatly increasing the adhesion and toughness of Gypsum board.
2. Improve the stability and strength of Gypsum board: In the production process of Gypsum board, Starch can form a stable gelling system with water and other materials, so that the surface of Gypsum board is smooth and not easy to warp, increasing the stability and strength of Gypsum board.
3. Prevent cracks and deformation on the surface of Gypsum board. Starch can form a protective film on the surface of the Gypsum board, thereby avoiding problems such as cracks and deformation on the surface of the Gypsum board.

Modified Starch Of Gypsum Board Main components It's made of Corn, can't be other corn; Main process: 1. The raw material is denatured, then the denatured raw material is made into starch. In the denaturation process, some organic substances ar added to reintegrate the molecules of the raw material, thus forming some new molecules. These new molecules will change the shape of the raw material, which will greatly increase the fluidity and elasticity of the raw material; 2. When the denatured raw material is made into starch, the purpose is achieved by freeze-drying the raw material. |

II. Core Advantages
Superior Adhesive Performance: During the production of gypsum boards, it forms a strong bonding force between the gypsum and the facing paper, significantly increasing the overall strength and impact resistance of the boards. Tests show that for gypsum boards produced with this product, the bonding strength between the facing paper and the gypsum core is enhanced by over 30% compared to ordinary products, effectively preventing quality issues such as paper peeling and delamination.
Excellent Film - Forming Property: As the gypsum slurry solidifies, the starch forms a uniform film that fills the pores between gypsum crystals, resulting in a smoother and flatter surface of the boards and improving their appearance quality. Additionally, the film - forming effect enhances the water resistance of the boards, reducing the risk of water absorption and deformation in humid environments.
Stable Product Quality: We adopt strict production processes and quality control systems. Every link, from raw material screening to finished product delivery, undergoes precise inspection to ensure consistent product indicators. The fluctuation range of key indicators such as viscosity, moisture content, and ash content is extremely small, providing reliable guarantees for customers' stable production.
High Production Adaptability: It is suitable for various gypsum board production processes, including the production of paper - faced gypsum boards, fiber gypsum boards, and decorative gypsum boards. The product dissolves quickly and has good dispersibility, allowing it to be evenly incorporated into the gypsum slurry rapidly. This reduces the mixing time, improves production efficiency, and cuts down on energy consumption costs.
Green and Environmentally Friendly: Using natural starch as raw materials, it contains no harmful chemicals and causes no environmental pollution during production and use. It complies with national environmental protection standards and the development trend of green building materials, helping customers create eco - friendly gypsum board products.
