Cable wire anti-icing coating to solve icing problems
HITS: DATE:2018-2-10 15:19:09

      Precipitation icing, sublimation and ice icing into electricity lines of icing, bring great inconvenience to people's lives and work, but also for the regional economic development caused huge losses. Beijing Zhixin Weihua Chemical Co., Ltd., located in the East Tieying Camp in Fengtai District, adopts the latest coating synthetic IPN technology in the world. It uses the silicon-containing inorganic polymer to modify the organic polymer to obtain alternate multi-block copolymers. The ZS -611 anti-icing coating, the paint coating smooth, high elevation, good flexibility to reduce friction, high adhesion, anti-icing adhesion performance. At the same time, the coating surface presents a low surface energy. By adding special surface active materials and nanometer rare earth oxides, through the interaction of each component and the synergistic effect, the coating has the advantages of low surface energy, high corrosion resistance, large binding force with the substrate, anti-blocking and anti-waxing properties Reached the advanced world level, ZS-611 anti-icing coating has been recognized by experts on the national grid power transmission line effect and widely used.
      Zhi-Wei Weihua anti-icing paint R & D personnel on a long-term field study found that, in addition to transmission line icing on the surface of the phenomenon of temperature is an important factor, the surface properties of the icing surface, in particular the size of the surface energy, surface adhesion to ice As well as the surface hydrophobicity has a greater impact on icing. Ice crystals are adsorbed on the icing surface, and continue to sediment, the size of this adsorption depends on the surface wetting between the ice and the ice surface, if it is a low surface energy hydrophobic surface, it It can be non-wetting between the ice crystal and the surface, which can greatly reduce the adsorption force on the ice crystal so as to effectively prevent freezing. Chi Shing ZS-611 anti-icing paint test results also show that, in order to reduce the surface of the water to prevent the freezing, the surface of the water contact angle greater than 90, the surface energy must be less than  25x10-3N / m or more can be fog Causing the icing to hang on the wire and cable, but the thickness of the pendant is not coated with a coating of anti-icing coating on the cable. The top of the cable can be covered with 5 cm around, coated with ice coating 1 to 1.5 mm thick, Fall ice flow thickness of 1 to 2 cm repeatedly broken off with the line to reduce the weight of ice covered, do not make the cable break, down the tower down accident.
