Problems solved by technology

[0002] At present, foam glass is widely used as a decorative material in the building materials industry, but the existing foam glass generally adopts a two-step molding method, that is, glass powder is added with calcium carbonate, carbon powder foaming agent, accelerator, etc., mixed and then loaded into a steel mold After the glass is softened, the bubbles formed by the foaming agent are used to make foam glass. After the steel mold is removed from the furnace, it is annealed. Then the uneven part of the surface is cut to make a homogeneous and same-color glass with concave holes on the surface The foam glass, in order to be used for architectural decoration, must be covered with other materials on the surface of the foam glass, so as to give full play to the advantages of heat insulation, sound insulation, non-combustibility, non-corrosion, and non-water absorption of the foam glass. Processing, which increases the cost of the product and hinders the wider application of the product

example 1

[0006] Mix the foaming agent (calcium carbonate, carbon powder type foaming agent) with glass powder, generally 100 kg of glass powder is placed in 20 kg of foaming agent, mixed and put into an open mold made of inorganic refractory material. And it is leveled, and then a layer of colored glass powder is laid on the glass powder mixed with the foaming agent, the thickness is 2-3mm, and then the open mold is heated in a furnace at a heating temperature of 800 degrees Celsius, and the heating temperature is about 800 degrees Celsius. After 10 minutes, the glass powder melts and the foaming agent foams. Due to the heat absorption on the wall of the inorganic refractory mold, the foaming agent near the wall of the inorganic refractory mold vaporizes first, while the glass powder does not show a viscous flow. At this time, the foaming of the glass layer at the wall of the inorganic refractory mold gradually weakens from far to near to form a transition from foam to micro-foaming into a...

[0008] Mix the foaming agent (calcium carbonate, carbon powder type foaming agent) with glass powder, generally 100 kg of glass powder is placed in 20 kg of foaming agent, mixed and put into an open mold made of inorganic refractory material. Then put the open mold into a furnace and heat it at a heating temperature of 800 degrees Celsius. After heating for about 10 minutes, the glass powder melts and the foaming agent foams. Due to the heat absorption on the mold wall of the inorganic refractory, it is adjacent to the wall of the inorganic refractory mold. The foaming agent at the place is vaporized first, and the glass powder is not in a viscous flow state. At this time, the foaming of the glass layer at the wall of the inorganic refractory mold gradually weakens from far to near to form a transition from foam to micro The foaming is transformed into a glass bulb. After the foaming of the glass powder mixed with the foaming agent at the open mold is basically completed, a layer ...

Abstract

The production process of foamed glass with one color glass shell of the same material includes the following steps: setting glass powder with mixed foaming agent inside opened mold of refractory inorganic material, spreading one layer of color glass powder on the glass powder with foaming agent, heating the open mold inside furnace to foam the glass, annealing and demolding. The color glass powder may be also spread after the glass foaming, and the color glass powder is then heated inside the furnace before annealing and demolding. The present invention has the advantage of producing foamed glass with one color glass shell of the same material in one-step formation process.

Description

Technical field [0001] The invention relates to a method for processing foam glass with a colored homogeneous glass shell on one side. Background technique [0002] At present, foam glass is widely used as a decorative material in the building materials industry, but the existing foam glass generally adopts a two-step molding method, that is, glass powder is added with calcium carbonate, carbon powder foaming agent, accelerator, etc., and then mixed into steel molds. After the glass is heated, the bubbles formed by the foaming agent are used to make foamed glass after the glass is softened. The steel mold is removed from the furnace and annealed, and the uneven surface is cut to make the same quality and color with concave holes on the surface. In order to use the foam glass for architectural decoration, it is necessary to cover the surface of the foam glass with other coverings, so that the foam glass has many advantages such as heat insulation, sound insulation, non-combustibil...
