Description
Technical field
The present invention relates to water cinder calcium silicate plate that a kind of refuse that utilizes coal water slurry boiler discharging produces and preparation method thereof.
Background technology
Calcium silicate board is one of important materials for wall that is applied to modern architecture, because of it has that density is low, intensity is high, bulking factor is little, fire prevention, moistureproof, mothproof, mildew-resistant; Workability is good, surfacing, premium properties such as elegant in appearance, is widely used as indoor partition wall, suspended ceiling decoration material in modern architecture.At present, calcium silicate board commonly used mainly adopts other organic fibres such as a large amount of former mineral substance and silica powder, slaked lime powder, fibrous magnesium silicate, paper fiber to make, constantly soaring along with the raw mineral materials price, its production cost height, and expend raw mineral materials, incompatibility environmental requirement.And coal water slurry boiler produces a large amount of waste residue etc. in the industries such as present pottery, cement, can use on calcium silicate board, but not obtain utilizing, and how carrying out refuse reclamation is a problem that is worth discussion.
Summary of the invention
The objective of the invention is and provide a kind of refuse to be recycled environment-friendly type water cinder calcium silicate plate that compliance with environmental protection requirements, cost are low, up-to-standard and preparation method thereof in order to solve above-mentioned deficiency.
The technical solution that the present invention adopts in order to achieve the above object is as follows:
This environment-friendly type water cinder calcium silicate plate, mainly make by raw material asbestos, paper fiber, slaked lime, silica powder, cement, it is characterized in that, its raw material also comprises water cinder and dust and produces the precipitation waste material that its concrete production formula is made of following proportioning raw materials (weight part): asbestos 90-100 part, paper fiber 30-34 part, slaked lime 75-85 part, water cinder 50-100 part, silica powder 235-265 part, cement 150-250 part, dust 20-35 part, production precipitation waste material 20-35 part.
Wherein, dust and produce the precipitation waste material and can adopt the dust that the purifying air of enterprises such as Production of Ceramics collects and dust, the sulphur removal of coal water slurry boiler to take off dirt water.
Its preparation technology's method is to comprise the steps:
One, preparation slip; Above-mentioned slag and cyclone dust removal powder are measured according to dry weight, desulfurization and dedusting water is directly pumped in the storage slurry stirred pot stir, it is stand-by the slip (concentration 2.5%) that stirs to be pumped into the test tank metering again; The paper fiber loosened earlier make 3.5-5% concentration, measure standby; With the fibrous magnesium silicate metering, loosen into concentration 3.5-5%, the slip that degree of loosening reaches more than 90% is stand-by, and other raw material meterings are stand-by;
The various raw materials that measure are sent in the hollander pull an oar, be prepared into uniform slip, concentration is controlled at 18%-21%; Slip in the hollander is pumped in the bucket type pulp storage tank, add the slip of producing the backwater neutralization, being diluted to concentration 13-16%;
Two, slab preparation; Slip after neutralization, the dilution is tiled in slurry at the uniform velocity the felt equably by head box after paste roller mill is discongested again, through the draining step by step of natural dehydration, vacuum, the moulding extrusion dehydration regulation moisture to 31%-34%; Be slit into specified dimension through horizontal rip cutting again, through product thickness, surface quality testing, salable product patrix stacking; The scrap stock unification of unacceptable product and salable product is reclaimed and is pumped into pulp storage tank after the slurrying again and produce;
Three, it is steam-cured to carry out slab, behind the salable product patrix, through 8 hours quiet naturally stop maintenance after the slab of the demoulding, send into autoclave with the form of the every still of 11 dollies and carry out steam-cured; It is main crystalline flyash silicic acid calcium component that product after steam-cured forms with holder shellfish mullite;
Four, sheet material processing, detection warehouse-in; After product after reaching steam-cured requirement shifts out autoclave, send into drying machine drying by every mode; Through check product thickness, outward appearance, moisture up-to-standard product, change sanding, edging, chamfering process again over to and carry out product specification size and chamfer machining, qualified through mechanical properties test again, the buttress heap puts in storage and gets final product.
Above-mentioned steam-cured main technologic parameters control: boosted constant voltage 14 hours, step-down 2.3 hours, pressure 1.0-1.1 MPa, temperature 180-182 ℃ 3 hours.
Above-mentioned oven dry main technologic parameters control: the high-temperature area temperature is controlled at 135-155 ℃.
The main quality of above-mentioned sanding: control thickness e＜± 0.2mm; Edging, chamfer quality control: the length and width standard size≤± 2mm; Chamfering width 26-28mm, chamfering degree of depth 0.6-1.0mm.
The beneficial effect that the present invention adopts above-mentioned technical solution to reach is:
Product of the present invention adopts the raw materials for production that are different from traditional calcium silicate board, made full use of industrial waste, the three wastes (the slag of coal water slurry boiler, dust, dirt water is taken off in sulphur removal), gathering materials on the spot turns waste into wealth, reduced the consumption of former mineral substance, reduced second environmental pollution, be example with 1 6T coal water slurry boiler after testing, day produces the about 400kg of slag, dust 600kg, desulfurization and dedusting water reaches 600T, and be mixed with the dust about 10% in the desulfurization and dedusting water, desulfurization and dedusting water (about pH value 5-6) is handled needs lime, day medication costs such as caustic soda reach 650 yuan, raw-material chemical ingredients of bonded products forming process of the present invention and bonding water (production cycle water ph value 14-15) are directly as desulfurization and dedusting water, thereby stablizing its pH value is controlled at about 8-9, utilize slag, dust sulfur oxide content situation, reduce the consumption of silica powder, produce product and reduced cost, the product physics that it is produced, mechanical property has reached the industry quality standard requirement of calcium silicate board fully, only because three wastes material color is greyish black, the product of producing is darker than common color, behind the process surface decoration, with common calcium silicate board indistinction.
