The application of ammonium metatungstate in the production of fire-resistant fabrics is mainly reflected in the following aspects:
Raw material addition
Ammonium metatungstate is one of the raw materials for fire-resistant fabrics and is added to the fabric fibers during the production process of fire-resistant fabrics. This can be achieved by mixing ammonium metatungstate with fiber raw materials before spinning, or by coating or impregnating the fabric with an ammonium metatungstate solution during the fabric production process.
Improve fire performance
The addition of ammonium metatungstate can significantly improve the fire resistance of fabrics. Ammonium metatungstate will decompose at high temperatures to produce water vapor and other non-combustible gases. These gases can dilute the combustible gas concentration in the combustion area and reduce the flame temperature, thereby inhibiting the combustion process. In addition, the oxide residue formed after the decomposition of ammonium metatungstate can also form a protective layer on the surface of the fabric, isolating the contact between flame and oxygen, and further preventing the progress of combustion.
Applications in the production process of fire-resistant fabrics
In the production process of fire-resistant fabrics, ammonium metatungstate is usually added during the fiber spinning or fabric finishing stage. In the fiber spinning stage, ammonium metatungstate is mixed with fiber raw materials and then spun to form fibers with fire-retardant properties; in the fabric finishing stage, the ammonium metatungstate solution is coated or impregnated on the fabric and processed through drying and other processes. Make ammonium metatungstate firmly adhere to the fabric.
Safety Precautions
Although ammonium metatungstate is an important fire retardant raw material, safety needs to be paid attention to during use. Ammonium metatungstate is a flammable substance. It should be kept away from fire sources and avoid situations such as high temperature and friction that may cause fires.
During the production process of fire-resistant fabrics, the amount of ammonium metatungstate added should be strictly controlled to avoid excessive addition that may lead to fabric performance degradation or safety hazards.
In summary, ammonium metatungstate plays an important role in the production process of fire-resistant fabrics by serving as a raw material additive for fire-resistant fabrics, significantly improving the fire-resistant performance of the fabrics. At the same time, you also need to pay attention to safety during use to ensure the safety of the production and use of fire-retardant fabrics.
