Embodiment 1

[0052] Present embodiment prepares cellular glass as follows:

[0053] Weigh 30% of the total weight, straw ash with a particle size range of 200-250 mesh and 70% of the total weight, with a particle size range of 140-200 mesh waste flat glass; use a mixer to mix the two evenly to obtain a mixture; Pour the mixture into the mold (450mm×350mm×100mm) on the table, adjust the vibration frequency of the vibrating table to 50HZ, and the amplitude to 5mm, and vibrate for 2s in the vertical and horizontal directions to make the distribution of the mixture dense and uniform; put the mold into In the furnace, rise from room temperature to 400°C at a heating rate of 5°C / min, and hold for 25 minutes; then rise to 900°C at a heating rate of 20°C / min, and hold for 25 minutes; then cool down to 600°C at a cooling rate of 20°C / min, Insulate for 30 minutes; then cool down to room temperature at a cooling rate of 1°C / min to obtain foam glass. The parameters of the cellular glass prepared by t...

Embodiment 2

[0055] Present embodiment prepares cellular glass as follows:

[0056] Take by weighing 25% of the total weight, coniferous ash with a particle size range of 200-250 mesh and 75% of the total weight, with a particle size range of 140-200 mesh embossed glass; adopt a ball mill to mix the two evenly to obtain a mixture; Pour the mixture into the mold (450mm×350mm×100mm), adjust the vibration frequency of the vibrating table to 50HZ, and the amplitude to 5mm, and vibrate in the vertical and horizontal directions for 3s to make the distribution of the mixture dense and uniform; put the mold into the furnace Inside, from room temperature to 450°C at a heating rate of 6°C / min, and hold for 20 minutes; then rise to 950°C at a heating rate of 15°C / min, and hold for 20 minutes; 30min; then cool down to room temperature at a cooling rate of 1°C / min to finally obtain foam glass. The parameters of the cellular glass prepared by this method are respectively: bulk density 165kg / m 3 ; Comp...

Embodiment 3

[0058] Present embodiment prepares cellular glass as follows:

[0059] Weighing sunflower stalk ash accounting for 20% of the total weight and having a particle size range of 200-250 mesh and waste bottle glass accounting for 80% of the total weight and having a particle size range of 140-200 mesh; using a mixer to mix the two evenly to obtain a mixture; Pour the mixture into the mold (450mm×350mm×100mm) on the vibrating table, adjust the vibration frequency of the vibrating table to 50HZ, and the amplitude to 5mm, and vibrate for 5s in the vertical and horizontal directions to make the distribution of the mixture dense and even; place the mold Put it into the furnace, raise the temperature from room temperature to 400°C at a heating rate of 7°C / min, and keep it for 25 minutes; then raise it to 900°C at a heating rate of 20°C / min, and keep it for 25 minutes; then cool it down to 600°C at a cooling rate of 15°C / min ℃, keep warm for 30min; then cool down to room temperature at a...

Abstract

The invention discloses a method for preparing foam glass with plant ash and waste glass. The method is characterized in that the plant ash and the waste glass are used as raw materials and mixed uniformly by a ball mill or a mixer so as to obtain a mixture; the mixture is poured into a die on a vibration table, enabled to be distributed densely and uniformly through vibration and then placed into a furnace to be fired, so that the foam glass is obtained. According to the method, a lot of solid waste of the plant ash and the waste glass is used, and no chemical additive is required, so that the production cost can be reduced substantially, the energy can be saved effectively, the environment can be protected, the waste can be changed into wealth, and the method has remarkable social benefit and economic benefit; the plant ash foam glass produced with the method is excellent in performance, has the advantages of light weight, high strength, good heat-insulation performance and the like, can meet requirements of buildings for heat insulation, is an excellent Level-A incombustible outer wall heat-insulation material and can be used as a substitute for roof and outer wall heat-insulation materials.

Description

technical field [0001] The invention relates to a method for manufacturing foam glass, in particular to a method for preparing foam glass by using plant ash and waste glass. Background technique [0002] The "2010 Building Energy Conservation Goals and 2020 Building Energy Conservation Long-term Planning Goals" issued by the Building Materials Industry Association stipulates that by 2010, fully start building energy conservation and promote green buildings, and the average energy saving rate will reach 50%; from 2010 to 2020, All building energy-saving standards have been fully implemented, with an average energy-saving rate of 65%. Since walls account for the largest proportion (accounting for about 50%) of the energy loss of Chinese housing and residential buildings, it is urgent to carry out a comprehensive renovation of building exterior walls, and the market for wall insulation materials will increase significantly. [0003] On the other hand, fire accidents caused by ...
