Abstract
The invention discloses a process for producing a thistle board by using desulphurization gypsum and natural gypsum, which comprises three process steps of milling, pulping and board making. The method uses the desulphurization gypsum and the natural gypsum according to certain proportion, reduces energy consumption of a manufacturing technique of the natural gypsum, effectively adjusts the grain composition of building gypsum powder, reduces the resource consumption while ensuring the normal production and the product quality of the thistle board, protects natural minerals and the environment, and achieves better effect of comprehensive utilization of resources.
Description
Technical field
The present invention relates to a kind of technology of utilizing the desulfurated plaster and the plaster of paris to produce Thistle board, belong to architectural decoration material field.
Background technology
Present domestic most building materials of gypsum enterprise is that main raw material(s) is produced with the plaster of paris, gypsum ore can prepare grain composition arbitrarily as required when producing, the power consumption of plaster of paris production technology is high, need to obtain to be used for after ore dressing, fragmentation, fine grinding, the calcining building gypsum plaster of Thistle board, and the plaster of paris belongs to non-renewable mineral resources, and exploitation will inevitably cause the influence of environment.
A large amount of destructions of using gypsum ores to cause the exhaustive exploitation and the natural environment of mineral resources are added the finiteness of plaster of paris resource, cause its price also to raise year by year.
Desulfurated plaster is from exhaust gas desulfurization industry, the hygrometric state calcium sulphate dihydrate crystal that particle is tiny, of high grade.Claiming flue gas desulfurization gypsum, sulphur gypsum or FGD gypsum again, is that the flue gas that burning produces to sulfurous fuels (mainly being coal) carries out the desulfurizing and purifying processing and the industry by-product gypsum of generation.China is that coal resource consumes big country, and the sulfur content of coal is higher, and thermal power generation is generally thought coal-fired main, accounts for about 1/3 of coal production, and a large amount of SO is all discharging every year in the coal-burning power plant
2, since 2002 implemented " clean production method ", country is the explicit order time limit coal-burning power plant desulfurization unit that starts, and each high-power station installs desulfurizer in succession, has produced a large amount of desulfurated plasters.
Desulfurated plaster is compared with the plaster of paris, and it is few to have an impurity content, and granularity is little, stable components, because its raw material free water content is between 10-15%, and viscosity is stronger, in the middle of loading, lifting, course of conveying, causes choking phenomenon, is unfavorable for automated production.In addition because grating is bad, the distribution of particles band is narrower than the land plaster of the plaster of paris after levigate far away, intensity is low after making building gypsum plaster, hard and crisp because of its property, mobile performance is bad, as producing Thistle board with it, be difficult to control conveying, metering, the feeding performance of its dry powder on the one hand, after adding water on the other hand and stirring, problem such as it is inhomogeneous to be easy to generate in the plate foaming, and plate core and mask paper bonding are not firm.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the invention provides a kind of technology of utilizing the desulfurated plaster and the plaster of paris to produce Thistle board, its technical scheme of taking is:
This technology comprises powder process, slurrying and making sheet three process, and concrete process is as follows:
(1) powder process
After the desulfurated plaster and the plaster of paris are pulverized removal of impurities respectively, desulfurated plaster is dried respectively, and the plaster of paris is levigate, and the desulfurated plaster after the processing mixes with the weight proportion of the plaster of paris according to 7: 3, the first continuous calcining of mixed material cools off homogenizing then and makes gesso;
(2) slurrying
The gesso of 100 weight portions adds the modified starch of 6 weight portions, the fortifying fibre of 6 weight portions, the blowing agent of 8 weight portions, the water reducing agent of 3 weight portions and the water of 70 weight portions and evenly makes slip after the stirring;
(3) making sheet
At first slip cuts off then with mask paper is adhesion-molded up and down, and final drying makes Thistle board.
The present invention with desulfurated plaster and the plaster of paris according to the special ratios admixture; reduce the power consumption of plaster of paris production technology; effectively regulate the grain composition of building gypsum plaster; when guaranteeing Thistle board ordinary production and product quality; reduce resource consumption; protect natural mineral products and environment, realize better comprehensive utilization of resources effect.
Good effect of the present invention is as follows:
1, utilize the desulfurated plaster and the plaster of paris to produce Thistle board, industrial residue is turned waste into wealth, saved the mineral resources of the plaster of paris again, the cost of gypsum plank also reduces greatly.
2, both are combined into raw material and produce building gypsum plaster and produce Thistle board to utilize desulfurated plaster, the plaster of paris, can reduce effectively that desulfurated plaster moisture is big, the particle branch wear narrow, to energy consumption, the influence of gypsum plank intensity.
3, desulfurated plaster is in the drum-type turn-around machine under the effect of lifting blade device, contain the big material of moisture and can be good at kicking up and pulverizing, material is heated evenly, and has avoided wall powder burn-off phenomenon, improved the heat energy utilization rate, had the advantages that oven dry is even, dehydration is fast, output is high.
The specific embodiment
Describe the present invention below in conjunction with embodiment:
This technology comprises powder process, slurrying and making sheet three process, and concrete process is as follows:
(1) powder process
1, after the desulfurated plaster and the plaster of paris are removed metal impurities by the crushing engine pulverizing respectively, desulfurated plaster enters in the roller dryer and dries, temperature is controlled at 100 ℃, and when the free water content in the material finishes oven dry when following 5%, it is levigate that the plaster of paris enters grinding machine;
2, the desulfurated plaster and the plaster of paris after the processing weighed according to 7: 3 weight proportion by belted electronic balance, enters then in the gypsum homogenizing storehouse to mix;
3, mixed material at first enters fluidized bed furnace, carries out continuous calcining at 200 ℃, when the crystallization water reduces to 6%, makes gesso after entering powder storehouse cooling and aging.
(2) slurrying
Gesso is sent into mixer through accurate weighing 100 weight portions of belted electronic balance, and the water that adds the fortifying fibre of water reducing agent agent, 6 weight portions of blowing agent, 3 weight portions of modified starch, 8 weight portions of 6 weight portions and 70 weight portions stirs evenly and makes slip.
(3) making sheet
At first up and down mask paper through splicing, correction, indentation operation after, slip and mask paper up and down is bonding sends into board-like forming machine, is delivered to cutting off machine through solidifying conveyor, according to customized cut-off, enters No. 1 laterally through quickening belt; Enter plaster tablet drying machine through dispenser then, this drier is by the circulating fluid bed hot-air furnace heat supply, and 220～280 ℃ of bake out temperatures make Thistle board after the drying; Last Thistle board is through operations such as go-on-go, side cut, automatic edge sealing, stacking, packing, quality inspection warehousing after passing.
