Abstract
A chimney white mud fiber reinforced calcium silicate sheet is mainly prepared from the following raw materials by weight percent: 6-12 percent of fiber, 1-3 percent of fiberglass, 15-20 percent of chimney white mud, 35-46.04 percent of quartz, 20-30 percent of common silicate cement and 1-2 percent of expanded perlite. The chimney white mud fiber reinforced calcium silicate sheet has the advantages as follows: the chimney white mud fiber reinforced calcium silicate sheet is manufactured via effectively researching Ca+ in the chimney white mud and using the characteristics of the gypsum at different temperatures; the strength is high, the appearance is beautiful, and the cost is low; the problem about the comprehensive utilization of the industrial desulfurized gypsum is solved, the production cost of the calcium silicate sheet is lowered, and the method which is reliable in technique, economical and feasible is developed for the fume desulfurized waste material, accordingly, both the environmental benefit and the economical benefit are obtained; the sewage recovered via vacuum dehydration during production is reused, and Ca+ in the sewage is completely used; the problem that raw wood pulp is directly applied to the production of the calcium silicate sheet is solved, and the wood can be comprehensively utilized.
Description
Technical field
The present invention relates to a kind of material of construction, particularly a kind of chimney white clay fiber reinforced 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, its CaO is high, and production environment is under some influence.
Excessive owing to adopting lime to strengthen the calcareous raw material cost of calcium silicate board as producd fibers, how production cost is urgent problem always.
Summary of the invention
Object of the present invention is just to provide a kind of desulfurated plaster (being chimney white clay) replacement lime that adopts chimney white clay to form, and producd fibers strengthens the chimney white clay fiber reinforced calcium silicate board of calcium silicate board.
Solution of the present invention is such:
1, adopt chimney white clay to replace the technical scheme of lime: 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 as a kind of byproduct thing 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 analyse and branch away, with Si
+in conjunction with generating calcium silicate board.
By the systems analysis of desulfurated plaster (the being chimney white clay) component to chimney desulfurization formation, and effective Ca under High Temperature High Pressure
+formation ratio research, utilize under 150 ° of-240 ° of C part Ca in desulfurated plaster (CaSO4)
+separate out, with Si
+hydrothermal synthesis reaction occurs, generate hydrated calcium silicate as gum material, in the future the sand grains of reaction bonds together and forms entirety, effectively improves the strength characteristics of calcium silicate board, and the sheet material of production is harder, attractive in appearance, smooth surface is fine and smooth, cost is low.
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 the calcareous raw material of CaO as producd fibers enhancing 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,
(7), in process of production vacuum hydro-extraction reclaim the firm recycle of waste water, the Ca in waste water
+arrived completely and utilized, cost is low, meets recycling economy requirement.
Accompanying drawing explanation
Fig. 1 is process flow sheet of the present invention.
Specific embodiment is as following table:
