There are many kinds of flame retardants, aluminum hydroxide flame retardants should be more familiar to everyone, generally used in some cables and wires, for the environment is not polluted. So, what is the impact of such products on humidity? In order to facilitate our future use, the following content is recommended for everyone to understand.
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 electrical energy, while electrical energy becomes heat energy, preparing conditions for thermal breakdown, increasing the possibility of thermal breakdown.
2. In the flame retardant of DC cables, materials with different resistivity can also be used to make flame retardant in order to improve the utilization rate of materials. Improving the surface resistivity is also very important for the flame retardant of cables. When there is dirt and water on the surface, due to its uneven distribution, some surfaces may bear higher voltage, resulting in partial discharge or surface discharge, resulting in serious failure.
3. However, it is sometimes necessary to reduce the surface resistance by artificial methods. For example, the conductive core of the cable, because the surface is not smooth, the electric field distribution is uneven, and the high electric field strength will cause corona discharge. After the surface of the conductive core is covered with conductive rubber or semi-conductive plastic, the electric field strength on the surface of the core will be reduced except corona. In addition, the moisture degree of the material can be judged according to the change of the resistance coefficient of flame retardant material.
4, due to the small conductivity is large, and the size of water molecules is much smaller than the polymer molecules, under the action of heat polymer macromolecules and the composition of the relative movement of the chain, water molecules are easy to penetrate into the polymer, so that the polymer conductive ions increased, and the flame retardant decreased.
The above is some of the effects of aluminum hydroxide flame retardant on humidity. I hope it can help you better. If you still have doubts about such products, you can contact our manufacturer.
