Tetrabromoether has fire prevention effect and is suitable for fire prevention treatment of walls, floors and finishes. In order to give full play to the use requirements of tetrabromoether, strict requirements must be put forward for the environment when using it to make it known to the public. The details can be learned through the following introduction.
1. The use conditions are a common problem. Tetrabromoether can be used no matter where it is used or what the material is, but there are many conditions to meet for the specific operation process.
2. When using, first consider the use environment, and first clean the surface to ensure flatness and integrity.
3. If the temperature is too high to add, sagging, cracking, discoloration and other phenomena may occur. Try to avoid direct sunlight to prevent accidents.
4. In addition to the temperature problem, the tetrabromoether state may also be affected by low temperature in a low temperature environment, becoming thick and stiff, and difficult to paint.
5. After the addition, pay attention to ventilation, which is more conducive to the drying of tetrabromoether and ensures the normal state. In addition, pay attention not to use it in a humid environment, so as not to affect the use effect. In a humid environment, moisture-proof measures should be taken, otherwise the use effect of tetrabromoether will be directly affected.
