Abstract
The invention relates to a double-faced uniform forming method of a gypsum plaster ceiling board. A manufacturing mould of the gypsum plaster ceiling board is divided into a pair of upper and lower mould group; an upper mould comprises an upper soft mould and an upper hard mould, and a lower mould comprises a lower soft mould and a lower hard mould; and the soft moulds are fixedly connected with the hard moulds. The double-faced uniform forming method comprises the following steps of: firstly pouring a right amount of gypsum slurry into the upper mould during work, wherein the gypsum slurry is spread and uniformly distributed in the upper mould and uniformly vibrated to be formed; after the gypsum slurry is dried to a certain degree, starting to pour the gypsum slurry into the lower mould; after the gypsum slurry is spread and uniformly distributed in the lower mould, covering the upper mould on the lower mould, combining and extruding the upper and the lower moulds, and integrally and uniformly vibrating for forming, wherein after the upper and the lower moulds are sufficiently solidified, gypsums inside the upper and the lower moulds are formed into a whole. The upper and the lower moulds both comprise an inner mould and an outer mould, wherein the inner mould is the soft mould (made from silica gel and other materials) so as to be convenient for the gypsums to be smoothly separated from the soft mould after formed, and a flash cave is arranged in the periphery of the lower soft mould so as to be convenient for storing the superfluous gypsum slurry of the lower mould when the upper and the lower moulds are combined; and the outer mould is made of hard materials (aluminum alloy and the like) so as to be convenient to fix and move. By adopting the method, the problems of rough surface, multiple pores and lower strength of a common gypsum plaster board are solved; and the produced gypsum plaster ceiling board has few pores, fine and smooth surface and high rigidity.
Description
Technical field
The present invention relates to the gypsum board manufacture field, specifically be meant the two-sided even forming method of a kind of gypsum plaster ceiling board.
Background technology
Gypsum plaster ceiling board is because of its light weight, environmental protection, ventilative being widely used on the building decoration.At present the most frequently used gypsum plaster ceiling board preparation method is that calcium plaster is injected flexible die, treat the gypsum sets moulding after, take away mould and promptly obtain plasterboard.Simple preparation method is only with a bed die, mixes up the die cavity coagulation forming of the calcium plaster injection bed die of ratio, takes away bed die and just obtains plasterboard, the shortcoming that this method exists is that plasterboard upper surface shape is difficult to control, rough surface, and pore is many, intensity is little, easy fracture.Improved method is to adopt two moulds up and down, the bed die that has die cavity is used for slip casting, patrix then is used to make limit muscle and reinforcement, only in counterdie, inject calcium plaster during making, then will on be molded into pulp surface, treat to take away behind the calcium plaster coagulation forming upper and lower mould and just obtain plasterboard with reinforcement.Owing to be to make by hand, the variable thickness of the plasterboard reinforcement that this method is produced, surface and inside still have a lot of pores, and surface quality is not high, and when surface smoothness and intensity were had higher requirements, this method also can't meet the demands.Other has other similar improving one's methods, but still does not solve the problem of producing the high-quality gypsum plaster ceiling board in batches.
Along with the sharp increase of plasterboard demand, in order to satisfy the production requirement of enterprise, improve the social production benefit, it is imperative to develop the high-quality gypsum plaster ceiling board production method of a kind of high efficiency.
Summary of the invention
Purpose of the present invention provides a kind of surface that mass-produces fine and closely woven bright and clean just in order to overcome above-mentioned the deficiencies in the prior art, and pore is few, the two-sided even forming method of the gypsum plaster ceiling board that hardness is high.
The objective of the invention is to be achieved through the following technical solutions.
The gypsum plaster ceiling board mfg. moulding die is divided into a pair of set of molds up and down.Patrix is by last soft mode and upper die, and counterdie is made up of following soft mode and following die, has fixedly connected between soft mode and the die.At first an amount of calcium plaster is injected patrix during work, calcium plaster shakeouts uniform in patrix, vibrate even moulding, treat that calcium plaster is dried to a certain degree, begins calcium plaster is injected counterdie, calcium plaster in counterdie, shakeout uniform after, on counterdie, the upper and lower mould matched moulds also pushes the even vibration moulding of one with upper mould cover, after treating that upper and lower mould fully solidifies, the upper and lower mould gypsum forms one.Because bolster is formed by internal mold and external mold, internal mold is soft mode materials such as () silica gel, is convenient to the demoulding smoothly after the gypsum moulding; In the counterdie soft mode periphery flash gutters is arranged, the unnecessary gypsum pulp-water of counterdie when being convenient to deposit the upper and lower mould matched moulds; Exterior sheathing is with hard material materials such as () aluminium alloys, is convenient to fixing and moves.This method has solved ordinary gypsum board rough surface, pore is many, intensity is low problem, and the gypsum board surface of being produced is fine and closely woven bright and clean, and pore is few, the hardness height.
The technical solutions according to the invention performing step is:
1. patrix slip casting: an amount of calcium plaster is injected patrix, and calcium plaster shakeouts uniform in patrix, vibrates even moulding.
2. counterdie slip casting: treat that the patrix calcium plaster does to a certain degree, begin calcium plaster is injected counterdie that calcium plaster shakeouts uniform, vibrates even moulding in counterdie.
3. matched moulds solidifies: with upper mould cover on counterdie, the upper and lower mould matched moulds and the extruding, the even vibration moulding of one, treat that upper and lower mould fully solidifies after, the upper and lower mould gypsum is an integrator.
4. delivery: after treating that calcium plaster fully is set in together up and down, take away mould up and down, the gypsum plaster ceiling board that obtains being shaped.
During the upper and lower mould matched moulds, patrix extruding counterdie calcium plaster makes the upper and lower mould gypsum can fully be connected in one; Under certain pressure, keep certain hour behind the matched moulds up and down, make the accurate assembly of calcium plaster.
Cope match-plate pattern inner surface of the present invention posts the soft mode that macromolecular material is made, and generally selects macromolecule organic silicon rubber or polyvinyl chloride resin etc. for use, utilizes the soft characteristic that can bend, be difficult for sticking gypsum of its material, is easy to realize the demoulding; Be difficult for loss simultaneously, but repeated multiple times is used.Lower bolster uses hard material, is convenient to fixing and mobile.
Further set forth content of the present invention below in conjunction with Figure of description.
Description of drawings
Fig. 1 is that upper and lower mould of the present invention cooperates the schematic diagram of making plasterboard.
Fig. 2 is the matched moulds schematic diagram of one embodiment of the present of invention.
