  • The loss of insulation board-ZTELEC GROUP

    2020-4-22u2002·u2002The moisture of the insulating plate on the surface of the insulating material has a very sensitive effect on its surface resistance. In particular, the adsorption force of water-absorbing substances such as polar materials on water is greater than the cohesion of water molecules, and it is easy to form a continuous water layer on the surface and reduce the surface resistance.
