Description
Gypsum Defoamer is a defoamer designed specifically for the foam problem in the gypsum production process. As an important raw material for building materials, decorative materials, and various industrial applications, gypsum often produces a lot of foam during the production process, which not only affects production efficiency but also may affect the quality of the final product. Our products can effectively control foam, improve production efficiency, and ensure the consistency of product quality.
Feature
High-efficiency defoaming performance
Our products adopt advanced chemical formulas, which can quickly diffuse and destroy the foam structure in the gypsum system, effectively inhibiting the generation and accumulation of foam. Secondly, after adding an appropriate amount of Gypsum Defoamer to the gypsum slurry, the foam height can be reduced to less than 10% of the original, and the defoaming time does not exceed 3 minutes.
Excellent temperature resistance
Our defoamer is specially designed to maintain stable defoaming performance in a high-temperature environment. Secondly, under high-temperature conditions of 100℃, the defoaming effect of our products is still significant, and the foam height reduction rate remains above 90%.
Good compatibility
The defoamer has good compatibility with the gypsum system and can be evenly dispersed in the gypsum slurry without affecting the physical and chemical properties of gypsum products.
Widely applicable
During the gypsum production process, the pH value of the slurry is usually in an acidic environment, and our defoamer can be used stably in an environment with a pH value of 4 to 9, whether in acidic or neutral conditions, it can effectively inhibit the generation of foam.
Applications
Construction gypsum production
In actual application, the amount of Gypsum Defoamer added is usually 0.1%-0.3% of the weight of gypsum. Even at a very small amount, the defoaming effect can reach more than 90%, which can improve production efficiency.
Decorative gypsum products
Our defoamer ensures the smoothness and fineness of the gypsum by quickly removing foam, making the surface of the decorative gypsum after molding smoother and more delicate.

FAQ
Q: How does Gypsum Defoamer work?
A: Gypsum defoamer works by breaking the surface tension of bubbles formed during the mixing of gypsum slurry. It disperses the foam, allowing air bubbles to collapse and preventing them from interfering with the quality and consistency of the final product.
Q: What are the main applications of Gypsum Defoamer?
A: Gypsum defoamer is mainly used in the production of plasterboard, gypsum plaster, gypsum-based cement, and other gypsum-based products. It is used to control foam during mixing, slurry preparation, and the setting process.
Q: How is Gypsum Defoamer applied?
A: Gypsum defoamer is typically added to the gypsum slurry during the mixing process. The recommended dosage varies based on the specific product and production conditions but is generally very small-often less than 0.05% of the total weight of the gypsum.
Q: Can Gypsum Defoamer affect the final quality of gypsum products?
A: When used properly, gypsum defoamer does not negatively impact the final quality of the gypsum product. It can enhance the quality by preventing air pockets and foam bubbles that could lead to defects. However, excessive use can cause issues such as reduced strength or surface appearance problems.
Q: How do you determine the appropriate dosage of Gypsum Defoamer?
A: The appropriate dosage depends on the specific formulation and the degree of foaming observed during production. It is typically determined through small-scale trials, where different concentrations of defoamer are tested to find the optimal balance between effective foam control and maintaining the desired product properties.
Q: Is Gypsum Defoamer safe to use?
A: Yes, gypsum defoamers are generally safe when used according to manufacturer guidelines. They are specifically designed for use in industrial applications, such as gypsum product manufacturing, and are typically non-toxic. However, it is important to handle any chemicals with care, following safety data sheet instructions to avoid unnecessary exposure.
