ELECTRON GRADE ZINC OXIDE

NANO-ZINC OXIDE FOR ANTISTATIC COMPOSITE MATERIALS

Nano-Zinc Oxide for Antistatic composite materials
    Anti-static additives primarily for the traditional carbon black, metal powder and surfactant. Carbon black for static additives can only get black products, the amount of damage will be great when some of the mechanical properties of materials. Metal anti-static additives in general a larger amount, about the quality of composite materials 40%, and susceptible to oxidation during processing, it is not easy oxidation of gold, silver, copper and other precious than that. Anti-static additives Surfactants with high relative humidity requirements of the environment and do not durable. And nano-Zinc oxide has a better anti-static effect. Zinc oxide whisker additive white osteoporosis-like appearance of the material, microstructure, compared with four three-dimensional needle-like single crystal, the angle between any two needles are approximately 109 degrees, the advantage of needle-like three-dimensional structure of four easy to form an effective three-dimensional network conductive channel through the tunnel whisker point discharge and antistatic effect to achieve the purpose, and with less; Zinc oxide stability, 1720 ℃ direct sublimation, and other materials is not easy chemical reaction, the durability of a good anti-static. In addition, the Zinc oxide whiskers is white, a variety of composite materials to meet color requirements.
