Abstract

------11/04/2566------(OCR) A formula for mixing gray-black wavy-surface tiles from waste materials consists of kaolin, rice husk ash, and green glass fragments. The production process is as follows: All raw materials are baked in an oven to remove moisture, then sieved through a 300-micron particle sieve. A dry mixing process with water spray is performed, followed by another sieving through a 600-micron sieve. The mixture is then molded using a one-way compression molding machine, dried in an oven, and fired in a kiln at a temperature increase rate of 100°C and maintained at 1050°C. The resulting product is gray-black wavy-surface terracotta tile that meets the strength standards of TIS 2508-2555. This invention promotes the creation of environmentally friendly terracotta materials, adds value to industrial waste, helps reduce environmental problems, lowers disposal costs for manufacturers, and provides consumers with more options. ------------ Page 1 of 1. Summary of the Invention: A formula for mixing gray-black wavy-surface tiles from waste materials consists of rice husk ash, kaolin, and green glass fragments. The manufacturing process is as follows: All raw material ingredients are baked in an oven to remove moisture, then sieved using a 300-micron particle sieve. A dry mixing process is then performed, followed by a water spray, and the mixture is sieved again using a 600-micron sieve. The mixture is then molded using a one-way compression molding machine, dried in an oven, and fired in a kiln at a temperature increase of 100 degrees Celsius and maintained at 1050 degrees Celsius. The resulting product is a dark gray wave-surfaced earthenware tile that meets the strength standards of TIS 2508-2555. This invention promotes the creation of environmentally friendly earthenware materials, adds value to industrial waste, helps reduce environmental problems, lowers disposal costs for manufacturers, and provides consumers with an alternative option.

------11/04/2566------(OCR) 1. The formula for the mixture of gray-black wavy-faced earthenware tiles from waste materials is as follows: - Kaolin 20% by weight - Rice husk ash 20% by weight - Green glass fragments 60% by weight 2. The manufacturing process of gray-black wavy-faced earthenware tiles from waste materials, as per claim 1, involves the following steps: a. Kaolin, rice husk ash, and green glass fragments are baked in an oven at 200 degrees Celsius for 2 hours or until all moisture is removed from the raw materials. b. The raw materials from step a are ground and sieved using a 50-mesh (300 micron) sieve. c. The raw materials from step b are mixed according to the specified ratio by hand, while spraying 10% water by weight of the raw materials to facilitate shaping. d. The raw materials from step c are sieved through a 20-mesh (600 micron) sieve to prevent particle clumping from the water spray. e. ... The raw materials obtained from step d are shaped into pieces using a single-direction compression molding machine at a pressure of 100 bar. The dimensions of the pieces are 50 x 100 x 7 mm (width x length x thickness). The pieces obtained from step e are then baked in an oven to remove moisture at 200 degrees Celsius for 2 hours. The pieces obtained from step f are fired in a kiln at 100 degrees Celsius and then at 1050 degrees Celsius for 1 hour. After the pieces obtained from step g have cooled, they are removed from the kiln. The resulting product is a dark gray wavy surface terracotta tile. ------------ Page 1 of 1 page. Claims. 1. The formula for mixing gray-black wavy-faced earthenware tiles from waste materials is as follows: - Kaolin clay (from wood grain) 20% by weight - Rice husk ash 20% by weight - Green glass fragments 60% by weight 2. The process of producing dark gray wave-surface earthenware tiles from waste materials involves the following steps: a. All raw materials are baked in an oven at 200 degrees Celsius for 2 hours, or until all moisture is removed. b. The raw materials from step a are ground and sieved using a 50-mesh (300 micron) sieve. c. The raw materials from step b are mixed according to the dry mixing formula by hand, with a spray of 10% water by weight to facilitate shaping. d. The raw materials from step c are sieved through a 20-mesh (600 micron) sieve to prevent particle aggregation. Step J: Take the raw materials from step D and shape them using a single-direction molding machine at a pressure of 100 bar. The dimensions of the finished product are 50 x 100 x 7 mm (width x length x thickness). Step F: Bake the finished product in an oven to remove moisture at 200°C for 2 hours. Step G: Fire the finished product in a kiln at a firing rate of 100°C and maintain the temperature at 1050°C for 1 hour. Step H: After the finished product from step G has cooled, remove it from the kiln. The resulting product is a dark gray wavy surface terracotta tile.
