Glass bubble,Hollow glass microspheres , Glass sphere beads, Manufacturer & suppliers

There are many preparation methods of hollow glass microspheres, such as flame, into the ball inside the furnace, Si – GDP (silicon doping glow discharge polymerization coating) spherical shells pyrolysis and sputtering method, etc. In many ways, furnace into a ball of mature technology, prepared by the quality of microspheres (concentricity, sphericity and wall thickness uniformity, etc.) is higher, and is suitable for batch production, hydrogen storage with hollow glass microsphere preparation is one of the main candidate method.Furnace into a ball method according to different raw material state can be divided into droplets method and dry gel method. Ball temperature range of the main equipment is more SPC vertical high temperature furnace, droplet method and the solution of sodium silicate on raw materials, raw materials by droplet generator change uniform droplets into the high temperature furnace, and raw materials for high gel method of dry gel particles. Using the furnace into the ball technology preparation of glass microspheres in 150 ~ 250 microns in diameter, wall thickness in 0.9 ~ 40. Mu m between. The diameter of the microspheres and the wall thickness can be adjusted by using condition.
Hollow glass microspheres hydrogen storage
Microspheres filling hydrogen equipment main function is to simply by changing the empty ball external hydrogen pressure and microsphere environment temperature, in order to realize the empty core ball of hydrogen. Hydrogen plant by vacuum system, high pressure gas source and control part, plenum chamber and road.Control part of the main function is to set and control of temperature, record the gas chamber in the process of temperature, pressure and the relation curve of time, temperature and pressure of gas chamber upper limit alarm and processing, etc.25 mpa plenum chamber maximum working pressure, temperature range for the room temperature to 450 ℃, the heating rate is 3 ~ 15 ℃, min 1, in the process of heating up the biggest deviation is less than 30 ℃, the maximum overshoot temperature less than 10 degrees Celsius, the temperature of the heating process to the constant temperature fluctuation time less than 20 min, the temperature drift when temperature is less than 0.5 ℃. Hollow glass microspheres can be studied by using the device condition of air pressure balance time and specific air pressure inside the ball.
