Description

Field of invention:

The present invention relates to the method of creating a high frequent, turbulent and directional movement of one or more expanded glass particles made from recycled glass and a blowing agent when entering a plastic state at high temperature to avoid sticking or merger of particles during the expansion phase. In the expansion phase the particles will move more than 85% of time in air.

Background:

There is an increasing demand for expanded glass pellets made from recycled glass to be used as insulants, lightweight aggregates in concrete, or fillers in epoxy, or other applications where low weight, low water absorption, flowability and high insulation capacity is needed.

Traditionally expanded glass pellets have been made from recycled glass powder, water glass, one or more additional blowing agents, and some time metakaolin, all mixed in order to form a slurry, then granulated into pellets and dried, to be foamed at temperature between 780<o>C and 950<o>C, preferably at temperatures below 850<o>C in a rotary kiln as mentioned in WO 2016/124428 A1.

Other prior art suggests the use of recycled glass powder and SiC as the blowing agent as part of a two-stage sintering process where foaming takes place at temperatures above 850<o>C, as mentioned in WO 2019/002561 A1.

To be able to produce an approximately spherical and expanded glass product at temperatures above 850<o>C with SiC as the blowing agent, the problem of sticking or merger of the particles when they enter a plastic state needs to be overcome, and especially when the production volume is large.

Prior art shows good results of using virgin kaolin powder as a release agent to overcome problem at process temperatures below 850<o>C.

On the other side, at temperatures above 850<o>C the release agent transforms into metakaolin and it loses some of its release agent properties. In addition, the metakaolin tends to melt into the surface of the expanded pellets in its plastic state due to the softening of the product, hence reducing the release properties of the agent. This problem increases as closer to the elastic state of the expanded glass pellets the foaming process needs to take place, and it increases with time at 3 operating temperature, and the amount of blowing agent used due to excess heat created from the exotherm reaction taking place inside the pellets that again reduces the viscosity of the expanded particle.

This invention overcomes the problem of prior art of sticking or merger of the expanded glass pellets at temperatures above 850<o>C and at all temperatures below the transition temperature where the expanded glass pellets enters an elastic state, making it possible to produce continuously large volume of expanded glass pellets and gaining economies of scale.

Summary of the invention:

The present invention provides a method of creating a high frequent, turbulent, and directional movement of glass particles that are applied to the surface of a horizontally angled plate body exposed to vertically angled g-forces at high temperature, the plate body being attached on top of a vibration table with a vibration engine attached under, where the frequency of the vibration engine is in the range from 25Hz to 75Hz.

Further embodiments of the method according to the present invention are described in the dependent patent claims.

The present invention has as one of its objectives to overcome the disadvantages of the prior art, by introducing a method to be able to make large volumes of approximately spherical expanded glass products at high temperature without any risk of sticking or merger of the expanded glass pellets before it has reached its solid state after cooling.

The present invention comprises a method to create a high frequent, turbulent and directional movement of one or more expanded glass particles at temperatures above 850<o>C and to avoid sticking or merger of the particles when entering a plastic state, but below the elastic state of the particle.

According to one aspect, the particles are added onto a horizontally angled vibrating plate body placed inside a furnace.

According to another aspect, the uniformly created and vertically angled g-force on top of the plate body, created by a vibration engine located under the plate body and outside the furnace, should be strong enough to create a turbulent movement in the particles, keep the particles in air more than 85% of the time, limit the time two particles are in direct contact with each other to not create any sticking or merger opportunities between them.

According to another aspect, the particles should move in one direction through the furnace to enable control of process time for each particle.

According to another aspect, different combinations of release agents are introduced to create a mineral on the surface of the particles and on the surface of the plate body, further reduce the risk of sticking or merger of particles or sticking to the plate body, when production volume is large.

According to another aspect, different combinations of water glass solutions are introduced to coat the particles to enhance strength or alter the surface of the particles or increase waterproofing of the particles or to bind dust.

According to another aspect, the expanded glass pellets can be used as filler in concrete, as filler in epoxy, as filler in artificial turf systems, or as filler in water filtration cartridges.
