Abstract
The invention discloses a process for producing thistle boards from phosphogypsum and natural gypsum, which comprises the three steps of pulverization, pulping and board manufacturing. The invention dopes the phosphogypsum and the natural gypsum according to the specified proportion and adjusts the process correspondingly, and can reduce the impurities in the phosphogypsum and the acid influence and simultaneously guarantee the product quality of the thistle boards, reduce the amount of the natural gypsum and protect mineral resources and the environment, thereby realizing better economic benefit and environmental benefit.
Description
Technical field
The present invention relates to a kind of technology of utilizing the ardealite and the plaster of paris to produce Thistle board, belong to architectural decoration material field.
Background technology
The a large amount of ardealite of annual discharging in the phosphate fertilizer industrial production, its main chemical compositions is CaSO42H
2O, identical with the plaster of paris, but show slightly acid, because of containing impurity such as P, F, free acid, the time of setting in the time of can slowing down the plaster of Paris aquation that makes, the intensity of reduction goods, domestic existing cement doping agent, the building building-block etc. of being used on a small quantity.All the other air storages that can only occupy cultivated land in a large number take a large amount of soils and deposit, and can cause surface water and environment pollution.
At present, the domestic widespread usage plaster of paris of the same trade is produced Thistle board, consider impurity and faintly acid that ardealite had, if use can cause the setting time when slowing down aquation separately, reduce product strength, phenomenons such as mask paper and plate core bonding are not firm, water requirement shakiness influence the ordinary production of Thistle board and reduce yield rate.
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 ardealite 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
Ardealite purifies the back removal of impurities, and is levigate after the broken deironing of the plaster of paris, and the ardealite after the processing and the plaster of paris mix homogenizing according to 7: 3 weight proportion, quick burning subsequently, and cooling and aging makes gesso at last;
(2) slurrying
The gesso of 100 weight portions adds the modified starch of 6 weight portions, the blowing agent of 8 weight portions, the setting accelerator 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 ardealite and the plaster of paris according to the special ratios admixture; correspondingly carry out the technology adjustment; can be in impurity in the middle of the reduction ardealite and acid influence; guarantee the product quality of Thistle board; reduce the consumption of the plaster of paris; protection mineral resources and environment, thus realize better economic benefit, environmental benefit.
Good effect of the present invention is:
1, utilize the ardealite 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 ardealite, the plaster of paris, faintly acid in the time of effectively reducing independent use ardealite, impurity are to the setting time of slip, with the adhesion strength of mask paper, the influence of the intensity of Thistle board.
3, adopt quick calcining process, raw material is once finished in the quick burning machine and is broken up, oven dry, calcining, with disposable the finishing of technology in three original steps, and adopt the pneumatic conveying drying method, it is fast that material is heated evenly heat transfer, improve the heat energy utilization rate, had oven dry even, dewater fast, high, the characteristic of low energy consumption of output.
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, purify ardealite, remove soluble impurity through washing, tramp iron separator enters storage bin after removing metal impurities;
2, the plaster of paris through crushing engine pulverize, grinding machine is levigate, the powder concentrator sorting enters storage bin;
3, the ardealite 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;
4, mixed material at first enters the quick burning machine, finishes at 200～300 ℃ and breaks up, dries, calcines, and when the crystallization water reduces to 8%, makes gesso after sending into 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 setting accelerator 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
The mask paper that slip is sent into board-like forming machine and top, bottom surface is combined into gypsum plank type just, through solidifying conveyor coagulation forming in course of conveying, the gypsum plank of cutting off machine after with coagulation forming cut by certain specification, send into drier oven dry (220～280 ℃ of bake out temperatures) by dispenser again, dry good gypsum plank is through operations such as go-on-go, side cut, automatic edge sealing, stacking, packing, quality inspection warehousing after passing.
Claims (1)
1, a kind of technology of utilizing the ardealite and the plaster of paris to produce Thistle board comprises powder process, slurrying and making sheet three process, it is characterized in that concrete process is as follows:
(1) powder process
Ardealite purifies the back removal of impurities, and is levigate after the broken deironing of the plaster of paris, and the ardealite after the processing and the plaster of paris mix homogenizing according to 7: 3 weight proportion, quick burning subsequently, and cooling and aging makes gesso at last;
(2) slurrying
The gesso of 100 weight portions adds the modified starch of 6 weight portions, the blowing agent of 8 weight portions, the setting accelerator 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.
