It should be noted that the above sequence of steps is not fixed, and can be adjusted according to the actual situation, for example: the step (2) can also be arranged after the step (3); the step (1) and the step (2) can be performed simultaneously, that is, after the scoring of one side of the lower protective paper is completed, when the other side is scored, the scored side can be folded or coated with an adhesive. The scored region is a region between the innermost score and the outermost score on the left side (or right side) of the lower protective paper sheet.
The gypsum board preparation method provided by the application can be used for manufacturing irregular gypsum boards at the edges of the boards and is applied to various splicing conditions, and the preparation method reduces errors (tolerance) of the gypsum boards and improves the quality of the gypsum boards by folding the lower protective paper with the dies after nicking. In addition, the gypsum board preparation method provided by the application has the advantages of compact and simple process, high reliability and long service life of the prepared gypsum board, and greatly improves the practicability of the preparation method.
In an exemplary embodiment, in step (1), one side of the lower protective paper is scored using an 8-score knife device, and the other side is scored using a 6-score knife device.
Fig. 2 is a schematic structural diagram of a workable gypsum board, in which 8 right angles are formed on the left side of the gypsum board, i.e., 8 creases are required to be formed, and an 8-point knife device is used for scoring, and 6 right angles are formed on the right side of the gypsum board, i.e., 6 creases are required to be formed, and a 6-point knife device is used for scoring. In fig. 2, in order to clearly show the structure of the gypsum board, the upper protective paper is not bonded on the lower protective paper, and gaps are left between the fillers and the left and right sides of the lower protective paper so as to clearly display the structure of the gypsum board.
In an exemplary embodiment, in the step (2), the adhesive is applied to both sides of the lower protective paper in a width range of 0.5 to 3 cm.
An adhesive is applied to both sides (inner surfaces of both sides, i.e., the side in contact with the fillers) of the lower protective sheet for subsequent fixing of the fillers disposed on both sides, the adhesive being applied in a width range of 0.5 to 3cm, for example, 0.5cm, 2cm or 3 cm.
In an exemplary embodiment, in step (3), the left and right sides of the lower protective paper are folded along the scores, and the left and right sides of the lower protective paper are folded into the shape as shown in fig. 2.
The lower protective paper is folded along the nicks through the die, so that the error of the gypsum board is reduced, the folding accuracy is improved, and the quality of the gypsum board is improved. In fig. 2, the left side and the right side of the lower protective paper of the gypsum board are folded upwards along the nicks, the front side and the rear side of the gypsum board do not need to be folded, the bottom of the lower protective paper forms a horizontal bottom surface, so that the lower protective paper forms a groove body capable of containing gypsum slurry (the left side and the right side are folded to form a shielding, and the front side and the rear side are not folded), the outlet of the mixer firstly starts spraying from the front side of the lower protective paper, the spraying is gradually carried out towards the rear side of the lower protective paper, the gypsum slurry on the front side is gradually solidified, and therefore the gypsum slurry which is not solidified at the rear side is blocked (the fluidity of the gypsum slurry is smaller), and the gypsum slurry is solidified on the lower protective paper.
In an exemplary embodiment, in the step (4), the filler is a three-dimensional porous mesh structure woven by glass fiber, one side of the filler has a shape corresponding to the shape of the lower protective paper after being folded along the score, and the other side of the filler is a vertical plane.
The filler is filled in a space formed by folding nicks on two sides of the lower protective paper, the shape of the filler is corresponding to that of two sides of the lower protective paper, the filler can play a role in supporting an edge structure, and the influence of cavity bubbles and the like on the quality of a final gypsum board is avoided when gypsum slurry is sprayed.
In an exemplary embodiment, in step (5), the gypsum slurry is ejected from the mixer outlet into the space formed by the folding of the lower liner paper
After being mixed according to a certain proportion, the gypsum slurry is poured into a mixer, and is fully mixed by the mixer and then is sprayed to a space formed by folding the lower protective paper.
In an exemplary embodiment, in step (6), the upper protective paper is fixed to the lower protective paper after being coated with 0.5-3cm wide adhesive on both sides.
The upper protective paper is coated with adhesive on both sides and then adhered to the lower protective paper to form a wet gypsum board, wherein the width of the adhesive coating is in the range of 0.5-3cm, for example, the width of the adhesive coating is 2 cm.
In an exemplary embodiment, wet gypsum board is dried in a dryer and cooled in the dryer after drying is complete.
And (3) placing the wet gypsum board for solidification, cutting the wet gypsum board by a cutting saw, drying and cooling the wet gypsum board in a dryer, and finally sawing edges and trimming the edges to obtain the finished gypsum board.
In an exemplary embodiment, the distance between adjacent scores is 1-17.5 mm.
In FIG. 3, the size of each part structure is indicated, wherein L1 is 3-5mm, L2 is 3-6mm, L3 is 1-3mm, L4 is 3.5-6.5mm, L5 is 3-6mm, L6 is 10.5-17.5mm, L7 is 4-6mm, L8 is 4-7mm, L9 is 4-7mm, L10 is 3.5-6.5mm, and L11 is 4-7 mm.
The distance between the nicks is not too short, so that the phenomenon that the structure formed after folding is too thin and is easy to break is avoided; meanwhile, the distance between the nicks is not too long, and inconvenience in assembly when the folded structure is used for clamping and splicing is avoided. The distance between adjacent nicks ranges from 1 mm to 7mm and can be adjusted according to actual needs. It should be noted that the distance between the respective scores is not necessarily the same, i.e., the width of the respective projections on the left side (or the right side) in fig. 2, the width of the respective planes, and the width of the respective grooves may be set according to actual needs.
The gypsum board preparation method provided by the application can be used for manufacturing gypsum boards with irregular edges and is applied to various splicing conditions, and in addition, the preparation method reduces errors (tolerance) of the gypsum boards and improves the quality of the gypsum boards by folding the lower protective paper with a die after nicking; through set up corresponding filler in mask paper both sides down, leave the bubble in the less space department in both sides when avoiding the spraying gypsum ground paste and influence gypsum board quality. The binder in the application can be the binder commonly used in the building industry, so that the production cost of the gypsum board is reduced. In addition, the gypsum board preparation method provided by the application has the advantages of compact and simple process, high reliability and long service life of the prepared gypsum board, and greatly improves the practicability of the preparation method.
