Abstract

DC60 (April 27, 2015) This invention describes a low-water-absorbent foamed glass product made from recycled glass and glass sediment. It consists of recycled glass, glass sediment, coloring agents, and a binder. The manufacturing process begins by finely grinding the recycled glass and glass sediment before mixing them with the coloring agents and binder. The mixture is then placed in molds, dried, and then fired in a high-temperature kiln to produce the low-water-absorbent foamed glass product. This product can be cut to the desired size and shape and is suitable for various applications, including soil moisture retention, thermal insulation panels, lightweight concrete blocks, and other uses. (Revised Invention Summary April 27, 2015) This product can be cut to the size and shape required by the user. It is suitable for various applications, such as soil moisture retention, thermal insulation panels, lightweight concrete blocks, and other uses as needed. --------------------------------------------------------------------------------------------------------------------------------------------------------- This invention describes a low-water-absorbing foamed glass product made from recycled glass and glass sediment.

Revised 27/04/2015 1. Low-absorption foamed glass products from recycled glass and glass sediment are characterized as consisting of: - Glass powder (particle size less than 74 µm) 60-90% by weight - Glass sediment powder (particle size less than 74 µm) 10-40% by weight - Coloring agent (size less than 45 µm) 1-10% by weight (of total glass powder) - Binder (5-20% by weight) (of total glass powder) 2. Low-absorption foamed glass products from recycled glass and glass sediment according to claim 1, where glass powder constitutes 60% by weight. 3. Low-absorption foamed glass products from recycled glass and glass sediment according to claim 1, where glass sediment powder constitutes 40% by weight. 4. Low-absorption foamed glass products from recycled glass and glass sediment. According to Reputation 1, where the coloring agent contains 1-2% of the total glass powder by weight; 5. Low-absorption foamed glass products from glass waste and glass sediment according to Reputation 1, where the binder contains 10% of the total glass powder by weight; 6. The process for producing low-absorption foamed glass from glass waste and glass sediment according to Reputation 1 consists of the following production steps: a. Finely grind the glass waste and glass sediment using an industrial edge runner; b. Select glass powder with particle size less than 74 micrometers (200 mesh) and sediment powder with particle size less than 74 micrometers (200 mesh) by sieving. Sediment that is still clumpy will be... A. Grind the glass powder again using an industrial grinder until a fine powder with particle size less than 74 micrometers (200 mesh) is obtained. B. Mix the glass powder and sediment powder from step B together. D. Add a coloring agent with a particle size less than 45 micrometers (325 mesh) and a binder, and mix thoroughly for 20-60 minutes using a dry mixer, then pour into ceramic molds. E. Dry the glass powder mixture in the ceramic molds from step D at 60-80°C in a hot air oven for 1-30 minutes to remove any binder that may cause uncontrolled air bubbles in the glass. F. Heat the dried glass powder mixture from step E in a batch-to-batch high-temperature kiln at 700-950°C at a heating rate of 5-10°C per minute and stand for 1-20 minutes, which is the optimal condition. This strengthens the internal structure of the bubble glass, making it less prone to breakage. B. Allow the bubble glass from step C to cool slowly in a kiln or through an annealing process. C. Cut the bubble glass from step G to the desired size and shape. 1. Low-water absorption foamed glass products from glass waste and glass sediment have the following characteristics: They consist of: - Glass powder (particle size less than 74 micrometers) 60-90% by weight - Glass sediment powder (particle size less than 74 micrometers) 10-40% by weight - Coloring agent (size less than 45 micrometers) 1-10% by weight (of the total glass powder) - Binder 5-20% by weight (of the total glass powder) 2. Low-absorption foamed glass products from glass fragments and glass sediment, as per claim 1, where glass powder constitutes 60% by weight. 3. Low-absorption foamed glass products from glass fragments and glass sludge, as per claim 1, where glass sludge powder constitutes 40% by weight. 4. Low water absorption foamed glass products from glass fragments and glass sediment, as per claim 1, where the coloring agent is 1-2% of the total glass powder by weight. 5. Low water absorption foamed glass products from glass fragments and glass sediment, as per claim 1, where the binder contains 10% of the total glass powder by weight. 6. The process for producing low-water absorption foamed glass products from glass waste and glass sediment, as per claim 1, consists of the following production steps: a. Finely grind the glass waste and glass sediment using an industrial edge runner. b. Select glass powder with particle sizes less than 74 micrometers (200 mesh) and sediment powder with particle sizes less than 74 micrometers (200 mesh) by sieving. Any remaining clumps of sediment are ground again using an industrial edge runner until a fine powder with particle sizes less than 74 micrometers (200 mesh) is obtained. c. Mix the glass and sediment powders from step b. d. Add a coloring agent with particle sizes less than 45 micrometers (325 mesh) and a binder, and mix thoroughly for 20-60 minutes using a dry mixer. The glass powder is then placed into ceramic molds. Next, the glass powder from step d is dried at 60-80°C in a hot air oven for 1-30 minutes to remove any binders that might cause uncontrolled air bubbles in the bubble glass. Finally, the dried glass powder from step e is subjected to a batch-to-batch high-temperature kiln at 700-950°C at a heating rate of 5-10°C per minute for 1-20 minutes. This optimal condition strengthens the outer structure of the bubble glass, preventing breakage. The bubble glass from step f is allowed to cool slowly in the kiln or through an annealing process.
