Abstract
A chimney white mud lime bamboo fiber-reinforced calcium silicate plate is prepared mainly by the following raw materials by weight: 6%-12% of lime bamboo fibers; 1%-3% of glass fibers; 20%-30% of chimney white mud; 25%-40% of quartz; 25%-35% of ordinary portland cement; and 1%-2% of expanded perlite. The advantages of the chimney white mud lime bamboo fiber-reinforced calcium silicate plate are that: the chimney white mud fiber-reinforced calcium silicate plate is prepared through effective study of Ca+ in chimney white mud and by making full use of the characteristics of gypsum at different temperatures; the strength is high; the appearance is beautiful; the cost is low; the raw material price is low; the impurities are few; waste water recovered through vacuum dehydration in the production process is recycled, and Ca+ in the waste water is completely used, which solves the problem of comprehensive utilization of industrial desulfurized gypsum, reduces the production cost of calcium silicate plates, and meets the requirements of circular economy.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of chimney white clay lime bamboo fiber reinforcement calcium silicate board.
Background technology
Density is low because having for fiber reinforced calcium silicate board, fire prevention, strong, the anticorrosion protection against the tide of sound-proofing, intensity advantages of higher, is therefore widely used in all kinds of buildings, in traditional method, take lime effective Ca in prepared using lime
+with SiO
2in Si
+produce calcium silicate board under certain condition, wherein unslaked lime CaO has certain influence to production environment.
Because the calcareous raw material cost that adopts lime to strengthen calcium silicate board as producd fibers is excessive, how to reduce production costs, be urgent problem always.
Summary of the invention
Object of the present invention is just to provide a kind of a kind of chimney white clay of industrial waste (being chimney white clay) replacement lime production lime bamboo fiber reinforcement calcium silicate board that adopts chimney white clay to form desulfurization.
Solution of the present invention is such:
The industrial residue that desulfurizing industrial fume forms, its major ingredient is calcium sulfite powder (being desulfurated plaster), there is identical rule with the physical and chemical performance of the plaster of paris, but the byproduct thing as a kind of flue gas desulfurization, general character matter is by flue gas desulfurization technique, make it there is some feature of reclaimed gypsum, have different with the plaster of paris, be mainly manifested in the aspects such as appearance property, particle characteristics, chemical composition, stability.
Chimney white clay main component is calcium sulfite, its unstable properties, and under certain temperature and humidity, wherein 30% ~ 35% Ca+ can separate out, with Si
+in conjunction with generating calcium silicate board.
By the systems analysis to desulfurated plaster (the being chimney white clay) component of chimney desulfurization formation, and effective Ca under High Temperature High Pressure
+formation ratio research, utilize under 150 ° of-200 ° of C part Ca in desulfurated plaster (CaSO4)
+separate out, with Si
+hydrothermal synthesis reaction occurs, generate hydrated calcium silicate gum material, other material adhesive is formed to integral body, effectively improve the strength characteristics of calcium silicate board, the sheet material of production is harder, attractive in appearance, smooth surface is fine and smooth, cost is low.
Solution of the present invention is such: a kind of chimney white clay lime bamboo fiber reinforcement calcium silicate board, mainly by containing following raw materials by weight, make: lime bamboo pulp fiber 6 % mono-12 %; Glass fibre 1 % mono-3 %; Chimney white clay 20 % mono-30 %; Quartzy 25 % mono-40%; Ordinary Portland cement 25 % mono-35 %; Pearlstone l % mono-2 %; Above-mentioned former wood pulp cellulose is added and appropriate water mill slurry after, then add other material slurrying, through stream slurry, vacuum hydro-extraction, moulding, rest, make finished product after the demoulding, steam pressure, oven dry.
Technical scheme also comprises more specifically: mainly by containing following raw materials by weight, make: lime bamboo fibers 7%; Glass fibre 2%; Chimney white clay 17%; Quartzy 46%; Ordinary Portland cement 25%; Pearlstone 1.6%.
Advantage of the present invention is:
(1), pass through Ca in chimney white clay
+effectively research, makes full use of the characteristic under gypsum differing temps, manufactures chimney white clay fiber reinforced calcium silicate board;
(2), intensity is high;
(3), appearance looks elegant;
(4), cost is low, realization utilizes integrated mill, the chimney waste residue desulfurated plaster (FGD) that enterprise's chimney dust removal desulfurization such as power plant precipitate substitutes CaO and as producd fibers, strengthens the calcareous raw material of calcium plate, greatly reduce raw materials cost, press CaO360 yuan/ton of calculating, chimney white clay reclaims 45 yuan/ton of prices, through high temperature, under high pressure, process the CaO that obtains 32.6%, only this item, per tonly cut down expenses 222 yuan, solved the comprehensive utilization of industrially desulfurized gypsum, reduced again the production cost of calcium silicate board, for flue gas desulfurization comprehensive utilization of waste material, to have opened up a technology reliable, economically viable approach, obtained the doulbe-sides' victory of environment and economy benefit,
(5), vacuum hydro-extraction is reclaimed in process of production cycling utilization of wastewater, the Ca in waste water
+arrived completely and utilized, cost is low, meets recycling economy requirement.
