Aluminum hydroxide flame retardant is a kind of flame retardant with aluminum hydroxide as the main raw material, which has strong flame retardant properties, so its appearance can basically prevent the further spread of fire and effectively protect the safety. Many users are concerned about their effects because their effects have a great impact on humidity.

1, generally require flame retardant not less than a certain value. If the flame retardant value is too low, the leakage current along the wire and cable line will inevitably increase, resulting in a waste of electric energy, and at the same time, the electric energy becomes heat energy, which prepares the conditions for thermal breakdown and increases the possibility of thermal breakdown.

2. Aluminum hydroxide flame retardant can also use material components with different resistivity to flame retardant in DC cable flame retardant, so as to improve the utilization rate of materials. Improving surface resistivity is also very important for cable flame retardant. When there is dirt and moisture on the surface, due to its uneven distribution, some surfaces may bear higher voltage, resulting in partial discharge or surface discharge, causing serious failure.

3. Reduce the surface resistance by artificial methods, such as the conductive core of the cable. Because the surface is not completely smooth, the electric field distribution is uneven, and the high electric field intensity will cause corona discharge. After the surface of the conductive core is covered with conductive rubber or semi-conductive plastic, the electric field intensity on the surface of the core will be reduced to eliminate corona. The moisture degree of the material can be judged according to the change of the resistivity of the flame retardant material.

4. Due to the small conductivity, the size of aluminum hydroxide flame retardant water molecules is much smaller than that of polymer molecules. Under the action of heat, polymer macromolecules and the relative movement of chain links make it easy for water molecules to penetrate into the polymer, increasing the conductive ions in the polymer and decreasing the flame retardant.

From the above, we can see the effect of aluminum hydroxide flame retardant on humidity. The flame retardant value is different, and the effect is not the same. We should correctly recognize the effect of humidity. Use them properly.
