Description
Technical field
The utility model relates to partition wall and uses light building material field, especially a kind of paper faced desulfurized gypsum hollow, light wt. partition.
Background technology
The Overseas New materials for wall mainly contains 3 large classes: hollow brick, concrete hollow block and building board.According to different building systems, load bearing wall adopts hollow brick, concrete hollow block, and non-load bearing inner partition wall adopts building board.The present building board output of China is 1.46 hundred million m2 approximately, about 0.88 hundred million m2 of gypsum plank wherein, light cellular partition board 0.58 hundred million m2.Although building board in novel wall material proportion near 5%, proportion 1% left and right only in whole materials for wall.Gypsum plank has been subject to suitable attention in the development of China, brought into play effect for promoting wall reform, but, light cellular partition board as the internal partition wall substitute does not but obtain general application, except be subjected to economics dictate and understanding not deep enough, also there are certain quality problems in light cellular partition board self: sheet material crack (comprise assembly unit crack) and sound-proofing are poor.
Light cellular partition board mainly contains following several: GRC porous batten, Aerated Concrete batten, light aggregate concrete batten, gypsum porous batten, color steel clamp heart batten and steel wire net rack filled board etc.The flue gas desulfurization gypsum light cellular partition board of Development of Novel should reduce drying shrinkage value, and emphasis solves the sheet material crack problem; Changing single row of holes is many rounds or filling core, improves the sheet material sound insulation value, satisfies a minute family partition wall requirement.Along with comfortable house and live in peace dwelling house to the modernization future development, large bay system ratio increases gradually, estimates that the demand of light cellular partition board is increasing, will have better growth momentum.
According to statistics, the gross reserves of China's plaster of paris is 570 * 108t, in these reserves, only have about 8% to be high-quality gypsum (referring to that mainly CaSO42H2O content is greater than 90% superfine and one-level gypsum) resource, the content of poor value and anhydrite is relatively many, and the distribution of China's Gypsum Mine is also inhomogeneous, has considerable area there is no gypsum resource.By desulfurated plaster and the plaster of paris more as can be known: the desulfurated plaster list can be used as the gypsum raw materials for production of high-quality with regard to its active constituent content.At present, the growth rate of gypsum industry is with the recovery rapid growth of global economy, and the application of desulfurated plaster in building material industry is more and more extensive.
The main component of desulfurated plaster is calcium sulphate dihydrate crystal CaSO42H2O, has identical rule with the physical and chemical performance of the plaster of paris, but as a kind of flue gas desulfurization byproduct, its character is determined by flue gas desulfurization technique, makes it have some characteristic of reclaimed gypsum.The particle diameter of desulfurated plaster particle is narrower, particle mainly concentrates on 30-50 μ m, grating is not as the plaster of paris, but its purity is higher than the plaster of paris, be embodied in the plaster of paris and mostly be impurity through coarse granule after grinding, fine grained mostly is gypsum, and the desulfurated plaster coarse granule mostly is gypsum, and fine grained mostly is impurity.The existing a large amount of desulfurated plasters of output of forcing can not be fully utilized, and produce serious environment pollution, and the raw material of plasterboard are reducing gradually, and separate with area of consumption the grown place.
Mainly desulfurated plaster is used for cement retarder and building plasterboard abroad, needs such as Germany is nearly all using desulfurated plaster with the enterprise of gypsum.Main as the production building product with as cement retarder.Other European countries are many is applied to produce paper faced desulfurized gypsum plate and building block with desulfurated plaster, also is useful on flyash activity exciting agent, soil conditioner and road basement material.Domestic existing multiple point is studied the development in desulfurated plaster-fly ash geopolymer, desulfurated plaster is carried out activity to be processed or chemi-excitation, the multiple trade waste that adds silicon-aluminum containing phase, calcareous component and containing sulfate etc., prepared product has architectural feature preferably, have certain mechanical property, the possible technique approach that provides is provided for it is efficient.
