I. Product Overview

This foaming agent is specifically developed for the gypsum board production process. It is prepared through scientific formulation and special processes, using environmentally friendly surfactants, foam stabilizers, and functional additives as its core components. The product is in liquid form, featuring excellent foaming properties, a stable foam structure, and good compatibility. It can significantly improve the density, pore structure, thermal insulation, and sound insulation performance of gypsum boards. At the same time, it optimizes the production process and reduces comprehensive costs.

II. Core Advantages

1. High - efficiency Foaming Performance：With a unique foaming formula, it has a high foaming multiple and can generate a large number of fine and uniform bubbles in a short time. After being mixed with the gypsum slurry, the foam has strong stability and is not prone to breakage and defoaming, ensuring the formation of a uniform and stable pore structure inside the board. This effectively reduces the board's density by 15 - 25 kg per cubic meter and improves the board's thermal insulation and sound insulation effects.
2. Excellent Stability：It demonstrates outstanding stability and uniformity of foam under different temperatures (5°C - 40°C) and humidity conditions, as well as complex production process conditions. Whether it is large - scale continuous production or small - batch customized production, it can ensure the consistency of product quality, reduce the rejection rate, and improve production efficiency.
3. Good Compatibility：It has excellent compatibility with various raw materials used in gypsum board production, such as building gypsum, facing paper adhesives, and starch additives. It does not react chemically with other additives and does not affect the setting and hardening process of gypsum. It can be quickly and evenly dispersed in the gypsum slurry without the need to change the original production process, making it easy to use.
4. Green and Environmentally Friendly：Environmentally friendly raw materials are selected, and there are no harmful gas emissions during the production process. The product is non - toxic and harmless, meeting national environmental protection standards and the development requirements of green building materials. Gypsum boards produced with this foaming agent can meet the environmental protection requirements of interior decoration, helping enterprises build green product brands.
5. Cost - effectiveness：By optimizing the foam structure, while ensuring the performance of the board, it can reduce the consumption of gypsum raw materials by 5% - 10%, reducing raw material costs. At the same time, due to the high stability of the product, production losses caused by quality problems are reduced, further saving comprehensive production costs.

IV. Application Effects

1. Enhanced Board Performance：Gypsum boards produced with this foaming agent have a reduced density of 600 - 800 kg/m³, a thermal conductivity that can be reduced to 0.12 - 0.18 W/(m·K), and a sound insulation effect improved by 10 - 15 dB. This effectively meets the requirements of building energy conservation and sound insulation design, making it suitable for applications such as partition walls and ceilings in high - end residential buildings, commercial buildings, hotels, and other places.
2. Optimized Production Process：The foaming process is fast and stable, and the foam is evenly mixed with the gypsum slurry, reducing mixing time and energy consumption. At the same time, the uniform pore structure accelerates the drying speed of the boards, shortening the production cycle by 10% - 15% and increasing the production capacity and turnover efficiency of the production line.
3. Increased Market Competitiveness：With its excellent product performance and green and environmentally friendly features, it helps enterprises produce differentiated and high - quality gypsum board products, standing out in the market competition, attracting more customers, and enhancing the enterprise's brand influence and market share.

FAQ

I. Product Characteristics - related

1. What are the differences between this foaming agent and ordinary foaming agents?

This foaming agent is specially customized for gypsum board production. Compared with ordinary foaming agents, it has significant advantages in foam stability and compatibility with gypsum slurries. The foam of ordinary foaming agents is prone to breakage, and when mixed with gypsum, it may affect the setting and hardening process. In contrast, our product has a foam half - life of ≥ 30 minutes, which can remain stable during the mixing and molding of the gypsum slurry without interfering with the normal setting of gypsum. Additionally, it can reduce the density of the board and enhance its thermal insulation and sound insulation performance, making it more suitable for the requirements of gypsum board production.

2. Are the main components of the foaming agent environmentally friendly?

Yes. This foaming agent is mainly composed of environmentally friendly surfactants, foam stabilizers, and functional additives. There are no harmful gas emissions during the production process. The product does not contain harmful substances such as heavy metals and formaldehyde, and the content of volatile organic compounds (VOC) is not detected. It complies with the GB 18582 - 2020 standard. Gypsum boards produced with this foaming agent meet the environmental protection requirements of green building materials and can be used with confidence in interior decoration.

3. How to determine the dosage of the foaming agent?

The dosage should be adjusted according to the target density and performance requirements of the gypsum board. Generally, when the dosage of the foaming agent is 0.8 - 1.2 kg per cubic meter of gypsum slurry, the density of the board can be reduced to 600 - 800 kg/m³. For the first use, it is recommended to conduct a small - scale test and fine - tune the dosage according to the test results. You can also contact our technical team to obtain a precise dosage plan based on your production process.

4. Does the foaming agent need to be diluted before use?

Yes, it does. It is recommended to dilute the foaming agent by mixing it with water at a ratio of 1:10 - 1:20, and use it after stirring evenly. Dilution can make the foaming agent disperse more quickly and evenly in the gypsum slurry, giving full play to the foaming effect. If the dilution ratio is inappropriate, it may result in uneven foam size or insufficient foaming volume.

5. At which stage of gypsum board production should the foaming agent be added?

It is recommended to slowly add the diluted foaming agent after the gypsum raw materials are mixed with water to form a slurry, and continue stirring for 3 - 5 minutes to ensure that the foam is fully and evenly mixed with the gypsum slurry. Then, the subsequent processes such as molding and drying can be carried out. Adding it too early or too late may affect the foaming effect and the quality of the board.

6. Will the foaming agent prolong the setting time of gypsum?

Yes, but within a controllable range. Under normal use, this foaming agent will extend the initial setting time of gypsum by ≤ 30 minutes and the final setting time by ≤ 60 minutes. This is because the presence of foam changes the internal structure of the slurry, but it will not seriously affect the overall production schedule. If further adjustment of the setting time is required, setting accelerators or retarders can be used in combination, and you can consult our technical staff for guidance.

7. What properties of gypsum boards can be improved by using this foaming agent?

Using this foaming agent can significantly reduce the density of gypsum boards, reducing the weight by 15 - 25 kg per cubic meter. At the same time, it can effectively improve the thermal insulation performance of the boards, with the thermal conductivity reduced to 0.12 - 0.18 W/(m·K), and the sound insulation effect is enhanced by 10 - 15 dB. This makes the gypsum boards more suitable for construction projects with high requirements for energy conservation and sound insulation, such as residential partition walls and commercial building ceilings.

8. Does the ambient temperature affect the use effect of the foaming agent?

Yes, it does. The applicable temperature range of this foaming agent is 5°C - 40°C. When the temperature is too low, the activity of the foaming agent decreases, the foaming multiple drops, and the foam stability deteriorates. When the temperature is too high, the foam may break quickly. If the production environment temperature exceeds this range, it is recommended to take heating or cooling measures, or contact us to obtain solutions for special working conditions.
