摘要:
A centrifuge apparatus and a method of using the apparatus to make hollow glass microspheres and hollow glass vacuum microspheres. The centrifuge has a plurality of coaxial blowing nozzles (55) disposed in the outer peripheral wall (20) of the rotor (1). Molten glass (4) is supplied to the centrifuge and by centrifugal force is caused to coat the inner wall surface (20) of the rotor (1) and be fed to the coaxial nozzles (55). A blowing gas or metal vapor blowing gas is supplied to the centrifuge and fed to the coaxial blowing nozzles (55). An entraining fluid (54) is also supplied to the centrifuge which flows through the centrifuge and is directed at the coaxial blowing nozzles (55). The hollow glass vacuum microspheres (67) are made by forming a liquid film of molten glass across the coaxial blowing nozzles (55), applying a metal vapor blowing gas (60) at a positive pressure on the inner surface of the glass film to blow the film which combines with the centrifugal force to form an elongated cylinder shaped liquid film (62) of molten glass which is detached by a jet (63) to form a hollow sphere (67).
