Embodiment Construction

[0029] A kind of production method of high roundness glass microsphere, it is characterized in that, comprises the steps:

[0030] a. On the cavity of the production device, a bead zone and a cooling zone are sequentially arranged along the length direction of the cavity;

[0031] b. Generate charged glass droplets through the production device of molten glass droplets in the prior art, and then blow the charged glass droplets into the beading area in the cavity 1 through a lateral high-temperature hot air flow, and the resulting The charged glass droplets are molten and have the same diameter;

[0032] c. The charged glass droplet is suspended in the cavity by the force of the electric field, so that under the action of the air flow in the horizontal direction, the charged glass droplet in the suspended state passes through the beading zone and cooling in sequence along the horizontal direction zone, and the charged glass droplets are raised in temperature when passing throu...

Abstract

The invention discloses a production method for high-roundness glass beads. The production method includes the following steps that a bead forming region and a cooling region are sequentially arranged in a cavity; electrified glass liquid drops are guided into the cavity; the electrified glass liquid drops are suspended in the cavity and sequentially pass through the bead forming region and the cooling region in the horizontal direction in the suspension state to obtain the high-roundness glass beads. The invention further discloses a production device for the high-roundness glass beads. The production device comprises a cavity, an electrode plate, a heating device, a cooling device, a side fan and a product collecting device. The production device has the advantages of being simple in structure, convenient to use and high in production efficiency.

Description

[0001] Technical field: [0002] The invention relates to the production field of glass microspheres, in particular to a production method and device for high-roundness glass microspheres. [0003] Background technique: [0004] The blowing method is one of the commonly used methods for producing glass beads at present. This method is to first melt the mineral raw materials into molten glass, and then use the high-speed hot air flow in the horizontal direction to blow the vertically falling glass liquid into droplets. Beads are formed under the action of their own surface tension, then cooled and collected. The production of glass beads by the blowing method has simple process, high beading efficiency, low cost, and good optical quality of the beads. The disadvantage is that the roundness of the beads is poor and often has defects such as "tails". It is easy to stick between the balls, and it is difficult to control the ball diameter. [0005] Invention content: [0006] The...
