Abstract

The production method of building material by using broken glass as main raw material includes the following steps: firstly, preparing adjuvant, then grinding broken glass to obtain glass powder, mixing glass powder, adjuvant, flyash and waste gas according to a certain mixing ratio, uniformly stirring, prilling, roasting to obtain artificial light aggregate which can be used as concrete aggregate. The similar process also can be used for producing sintered brick and tile and filtering material in water treatment equipment,

Description

A kind of is the manufacture method of the building materials article of primary raw material with cullet

Technical field

The present invention relates to a kind of is the manufacture method of the building materials article of primary raw material with cullet, belongs to city garbage burning ash and industrial slag and handles and the ecological environment field.

Background technology

The mankind enter 21 century, expansion in the dough figurine, ecological deterioration and shortage of resources three big problems.Because urban population is increased sharply, the municipal refuse discharge capacity is also increased sharply.With Beijing is example, and the solid refuse discharge capacity was about 6,000,000 tons in 2000, and wherein cullet content is about 8.7%, about 500,000 tons.Because technology and economic cause are very low to the utilization rate of cullet.The U.S. also had only 25.7%, and was about 3.2Mt the recovery utilization rate of cullet in 1996.Also a large amount of simultaneously discharging flyash, phosphorus slag and sewage sludges.How with resources such as a large amount of cullet, flyash, phosphorus slag and sewage sludges, produce and make ecomaterial, be used for aspects such as construction project or environmental protection, improve people's ecological environment, be the problem that current mankind presses for solution.

Summary of the invention

For the resources such as a large amount of cullet, flyash, phosphorus slag and sewage sludge that people's daily life is produced, the present invention proposes a kind of is the manufacture method of the building materials article of primary raw material with cullet, under the situation that adds auxiliary agent, utilizing cullet powder, incinerator ash, sewage sludge, flyash etc. is raw material, easy fired obtains building material mades such as brick and tile.

What the present invention proposed is the manufacture method of the building materials article of primary raw material with cullet, comprises following each step:

1, at first make auxiliary agent:

Auxiliary agent 1: boride: the mass ratio of carbonate=1: 0.5-2, boride can be native borax, borax, boric acid etc.,

Auxiliary agent 2: sodium metasilicate: graphite powder or coke powder=1: 0.5-2,

Auxiliary agent 3: boride: carbonate: antimony bloom=1: 0.5-0.2: 0.4, antimony bloom wherein be dry powder not, can be natural products or industrial goods, carbonate powder wherein can be calcium carbonate, magnesium carbonate or sodium carbonate etc.;

The material of above-mentioned three kinds of different proportionings is put into the mixing of milling machine, levigate back respectively by 200 orders, promptly obtain three kinds of different auxiliary agents;

2, the glass pulverizing and jevigating is passed through 200 orders, obtain glass dust;

3, make artificial lightweight aggregate:

Any and flyash in three kinds of auxiliary agents of glass dust and above-mentioned the 1st step preparation (or incinerator ash, sewage sludge etc.) and waterglass are cooperated by following mass ratio:

Glass dust: auxiliary agent: flyash (or incinerator ash, sewage sludge): waterglass=100: 1-2: 0-300: 20-50,

The said ratio material is stirred, balling-up, pellet particle diameter 5-10mm, 800-900 ℃ of calcining 20-30 minute, can obtain apparent density was 0.5-1.5g/cm ³, bulk density is 300-800g/cm ³The artificial light aggregate, this artificial light aggregate useful as concrete aggregate;

4, make fired brick, watt:

Any and following raw materials according in three kinds of auxiliary agents of above-mentioned preparation is proportioned:

Glass dust: auxiliary agent: flyash: waterglass=100: 2-4: 200-400: 20-40

Stir, at 5-10Kg/cm ²Pressure under be prefabricated into base, 200-400 ℃ of down oven dry, 850 ℃-900 ℃ roasting 30-40 minute, lower the temperature, coming out of the stove obtains sintered brick and tile;

5, make dank material:

Glass dust: auxiliary agent: quartz sand: waterglass=30-40: 0.5-10: 100: 8-10 stirs each component raw material, makes slab or pipe, under 800-900 ℃, burn till, constant temperature 25-30min, cooling is come out of the stove, get dank material, can be used for the filtrate in the water treatment facilities.

What the present invention proposed is the manufacture method of the building materials article of primary raw material with cullet, the balling-up of cullet powder, or cullet Lou and incinerator ash, sewage sludge, flyash etc. is shaped to brick and tile respectively, and easy fired obtains building material mades such as brick and tile.Also can with natural siliceous sand, phosphorus slag equigranular material, proportion, burn till permeable sheet material or permeable tubing after the moulding, be used for sewage disposal.This method becomes municipal refuse, industrial residue and water treatment plant's mud etc. into resource, develops and produce various building material products, serves architectural engineering, environmental project, saves the resource and the energy, and improves environment, has good society and economic benefit.
