Problems solved by technology

At present, the commonly used calcium silicate board is mainly made of a large amount of raw minerals and other organic fibers such as quartz powder, slaked lime powder, asbestos fiber, paper fiber, etc. With the rising price of mineral raw materials, its production cost is high, and it consumes minerals. Raw materials, not suitable for environmental protection requirements
At present, coal-water slurry boilers in ceramics, cement and other industries produce a large amount of waste residue, etc., which can be used on calcium silicate boards, but have not been utilized. How to reuse waste is a problem worth exploring

Embodiment 1

[0019] This environment-friendly water cinder calcium silicate board, considering that the color of the product is basically close to ordinary ones, it is composed of the following component distribution (parts by weight): asbestos 95kg, paper fiber 32kg, slaked lime 80kg, water cinder 50kg, quartz powder 265kg, 200kg of cement, 30kg of dust, and 30kg of wet production sediment waste. Water coal slag is composed of slag, dust, desulfurization and dust removal water produced by coal water slurry boiler.

[0020] Its preparation process comprises the following specific steps:

[0021] 1. Prepare the slurry; measure the above slag and dust powder according to the dry weight, pump the desulfurized and dust-removed water directly into the slurry storage mixing tank for stirring, and then pump the stirred slurry (concentration 2.5%) into the metering tank for measurement Stand-by; loosen the paper fiber first to make a concentration of 3.5-5%, and measure it for later use; measure ...

Embodiment 2

[0029] This environment-friendly water cinder calcium silicate board, without considering that the color of this product is basically close to that of ordinary products, it is composed of the following component proportions (parts by weight): asbestos 100kg, paper fiber 32kg, slaked lime 80kg, water cinder 100kg, 235kg of quartz powder, 200kg of cement, 30kg of dust, and 30kg of production sediment waste.

[0030] Since the preparation method is the same as the above-mentioned embodiment, it will not be repeated here; but the difference is that the color of the three wastes is gray and black, and the color of the product obtained is darker than that of ordinary products, and after surface decoration, it is no different from ordinary products. up.

Abstract

The invention discloses an environmental friendly calcium silicate board of water cinder, which is manufactured from raw materials of asbestos, paper fiber, hydrated lime, quartz powder and cement, and is characterized in that: the raw materials further comprise water cinder and dust and manufactured precipitation waste. The specific manufacturing ingredients is composed of the raw materials in proportion (part by weight): 90 to 100pbw of asbestos, 30 to 34pbw of paper fiber, 75 to 85pbw of hydrated lime, 50 to 100pbw of water cinder, 235 to 265pbw of quartz powder, 150 to 250pbw of cement, 20 to 35pbw of dust and 20 to 35pbw of manufactured precipitation waste. At the same time, the invention discloses a preparation method of the environment friendly calcium silicate board of water cinder which comprises steps that slurry is prepared firstly, then slabs are produced and steam cured and processed for board material, finally the board material is stored after detection. The invention has the advantages of environment protection, cost saving and stable quality, etc.

Description

technical field [0001] The invention relates to a water coal slag calcium silicate board produced by utilizing waste discharged from a coal water slurry boiler and a preparation method thereof. Background technique [0002] Calcium silicate board is one of the important wall materials used in modern buildings, because of its low density, high strength, small wet expansion rate, fire prevention, moisture resistance, moth resistance, mildew resistance; good processability, smooth surface and beautiful appearance Generous and other excellent properties, it is widely used as interior partition walls and ceiling decoration materials in modern buildings. At present, the commonly used calcium silicate board is mainly made of a large amount of raw minerals and other organic fibers such as quartz powder, slaked lime powder, asbestos fiber, paper fiber, etc. With the rising price of mineral raw materials, its production cost is high, and it consumes minerals. Raw materials are not su...
