What if the concentration of halogen-free flame retardant is too high during use?

There are many problems in the use of halogen-free flame retardants. However, only by understanding the causes and solutions can the problems be solved correctly. Some customers may think that the higher the concentration of halogen-free flame retardants, the better the flame retardancy effect. Therefore, the higher the concentration of halogen-free flame retardants, the flame retardants will change to a certain extent. What should be done if the concentration of halogen-free flame retardants is too high in the use process? Now let's have a look with the halogen-free flame retardant manufacturer.

1. Proper amount of water can be added to reduce the concentration of flame retardant fabric (fabric and wood) treated with high concentration of halogen-free flame retardant.

2. Shorten the treatment time of halogen-free flame retardant. Such as shortening the time of soaking fabrics and wood with halogen-free flame retardant.

3. Stop treating the flame retardant immediately and continue to treat with low concentration halogen-free flame retardant.

Flame retardants with good performance generally meet the following requirements:

1. It has high flame retardant efficiency and can easily make the flame retardant materials reach the required flame retardant level;

2. It has little influence on the physical properties of the materials, and the physical properties of the flame retardant materials manufactured after use should not be greatly changed;

3. It has good compatibility with materials, can be evenly dispersed in the flame retardant materials, and has good affinity; 4. The processing technology is feasible and can be used with traditional technology;

4. Affordable price, high cost performance ratio, and the cost of flame retardant materials can be accepted by the market;

5. Environmental protection, non-toxic, no release of harmful substances.

Flame retardant is a common auxiliary used to prevent or reduce the combustion possibility of combustibles. The current market situation of flame retardant is as follows.

1. Inorganic flame retardants such as magnesium hydroxide and aluminum hydroxide are not only low-cost green environmental protection products, but also have low flame retardancy, requiring a high amount of additives to make the material flame retardant. Moreover, inorganic flame retardants have poor compatibility and affinity, which greatly reduce the impact resistance of the material or the flexibility of the material. Therefore, they are often used in occasions where the mechanical properties of the material are not high.

2. Inorganic flame retardants such as antimony trioxide and zinc borate are often used as flame retardant materials, but their flame retardancy is mainly reflected in assisting other halogen flame retardants in flame retardancy, and their flame retardancy is very low or almost no.

3. Many foreign environmental friendly flame retardants also have relatively high flame retardancy to corresponding materials, and can produce flame retardant materials with good mechanical properties and good appearance. However, perhaps due to price and technology, the promotion in China is not very good.
