Production of Glass Bubble

2015-01-16 06:56:15

Glass bubble flotation method commonly used flame, release agent production method and the injection method. Where the blowing method is a molding method, generally using mineral raw materials for production. Flame floating method and release agent law is secondary molding method, usually recycled glass as raw materials to produce, more common in domestic applications.
The basic principle of flame float method is that the recycled glass is crushed into particles of a certain size, and in such a way the glass particles into a flame, under the action of the flame, glass particles softened, melted, beads oriented, cooled and solidified i.e. become a glass bubble.
The basic principle of the release agent law the waste glass is broken into small particles and mixed with a certain percentage of a release agent (such as graphite), fed at a constant speed rotating drum heated, glass particles under the effect of surface tension of beads after cooling washing, drying was finished. The method generally used to produce fine beads. Hollow glass bubble diameter is generally between 10 ~ 250μm, the thickness may be controlled according to requirements. Hollow glass bubble usable waste glass and water glass as the main raw material used to manufacture. Production process is broadly divided into beads and bead molding blank firing blanks in two phases, the basic approach is that in the thermal field, the use made of the colloidal suspension spray method to a diameter of glass powder and sodium silicate solution formed following 1um droplets. Endothermic temperature drops, the water acts as a foaming agent to the surface of the glass powder agglomeration, concentrated sodium silicate to the surface, forming shell beads from glass powder and water glass preform formed. Semi-finished beads tower sintering furnace, after melt, foam and annealing process is finished baking beads.
