        玻璃微珠--Glass Microspheres
        Glass Microsphere(Glass Beads)
        Glass Bead is colourless and transparent ball, no visible bubbles and impurity.
        And available for different uses, including surface treatment, road marking, reflective, decorative and etc.

        Product Description :
        High strength glass beads ( blasting and peening ) 
        It takes compressed air as the momentum and uses glass bead as the medium, through high-speed and high-pressure jetting on the surface of workspace. Products after shot blasting can eliminate the tensile stress, lengthen the fatigue life, and improve its capacity for anti-stress corrosion. 

        Usage :
        Micro glass beads are widely used as one new type of material in medical treatment, nylon, latex, engineering plastic, and aviation fields, for example, the filler and intensifier.

        Advantages :
        The glass beads made of the soda-lime silica glass has the good chemical stability, certain mechanical intensity and hardness, so as polishing grind.
        Material compared to other grind materials has the very big superiority. 
        Cannot pollute the processing metal. 
        May accelerate the cleaning up, make the processing material to restore originally clean, smooth.
