Flame retardant application of biguanide phosphate in building wood

Guanidine Phosphate (Guanidine Phosphate) as an efficient and environmentally friendly flame retardant, can significantly improve the fire resistance of building wood and enhance the safety of buildings when used in construction. Its multiple application methods (coating, impregnating agent, additive) allow Guanidine Phosphate to be flexibly adapted to different construction needs and usage scenarios. However, attention should be paid to the potential impact on human health and the environment during use, and appropriate protective measures should be taken to ensure safe and effective use. Guanidine Phosphate provides a reliable flame retardant solution for the construction industry and has broad application prospects.

This article will provide a detailed introduction to the application methods of Guanidine Phosphate in building wood, its potential impact on human health, and its main benefits.

Application Methods:

1. Apply a coating of phosphoric diamidate by spraying, brushing, or rolling it evenly on the surface of the wood. Make sure the coating thickness and evenness are consistent to achieve the best fire-resistant effect. The coating forms a protective film that effectively reduces the combustibility of the wood surface and improves the wood's fire resistance. The coating not only slows down the spread of flames but also releases fire-retardant gases at high temperatures, further suppressing the fire.

2. It can be used as an impregnating agent by dissolving phosphoric diamidate and water in the required proportion and immersing the wood in the phosphoric diamidate solution to allow it to penetrate fully into the wood. The soaking time and solution concentration need to be adjusted according to the type and size of the wood to ensure the treatment effect. The impregnation treatment not only protects the wood surface but also allows phosphoric diamidate to penetrate into the wood interior, providing more comprehensive protection. The treated wood is harder to burn at high temperatures or in a flame, extending the escape time for people in a fire.

3. It can be used as an additive during the production of wood products, such as plywood and fiberboard, by adding phosphoric diamidate as an additive. In this way, the wood has fire-resistant properties during manufacturing. After being processed, the finished wood product does not require any further treatment and can be used directly in construction, significantly improving its fire resistance and saving the cost and time of subsequent treatment.

Potential Impact on the Human Body

1. Phosphonic acid dihydrazide has a certain toxicity and may cause skin, eye, and respiratory system irritation. Long-term exposure may result in skin allergic reactions. Personal protective equipment such as gloves, safety glasses, and face masks should be worn when using it to avoid skin contact and inhalation of dust or vapor. A good ventilation system should be set up in the operation area to reduce the accumulation of harmful substances.

2. Some phosphonic acid dihydrazide products may emit volatile organic compounds (VOCs) that may affect air quality, especially when used in enclosed spaces. Good ventilation should be maintained during use, and low-VOC or VOC-free formulations should be used to reduce the impact on indoor air quality.

3. Safety measures should be taken in the workplace when handling and applying phosphonic acid dihydrazide. Avoid fire sources and high temperatures. Strictly follow safety operating procedures and ensure a clean and fire-free workplace. Regularly train employees to ensure they are familiar with safe operation and emergency response procedures.

Benefits of Applying Phosphoric Diamide:

1. Fire-resistant Performance, phosphoric diamide can significantly reduce the combustibility of wood. By forming a carbonized layer and releasing fire-retardant gases, it inhibits flame spread and extends the evacuation time during a fire, reducing damage to buildings and people.

2. Enhanced Safety, the fire safety of building wood is improved by applying phosphoric diamide. It enhances the overall fire resistance of buildings, especially suitable for high-rise buildings, public facilities, and buildings requiring high fire protection.

3. Increased Durability of Wood, phosphoric diamide enhances the durability of wood, resisting the growth of mold and fungi. It extends the service life of wood and reduces maintenance and replacement costs, suitable for wood applications in humid environments.

4. The application of phosphoric diamide meets building codes and fire safety requirements. It meets the standard requirements of building projects and complies with relevant safety standards, making it easier for fire inspections to pass.

5. Phosphoric diamide is a relatively environmentally friendly flame retardant that does not contain bromine compounds and chlorine compounds, reducing negative impacts on the environment. It has a smaller impact on the environment and human body during production and use, helping to achieve green building and environmental protection goals. 6. Phosphoric dimonium amide is multifunctional, in addition to its flame-retardant function, it also has the function of increasing the stability and resistance to moisture of wood. It reduces the problem of wood swelling and deformation due to moisture, enhances the structural stability of wood, and has certain antibacterial and antifungal properties.
