- the gypsum board waste introduced into the dusting machine is wet, machine troubles are likely to occur. For this reason, the gypsum board waste material is generally removed in a dry state. It is introduced and processed. However, when crushing dry gypsum paste waste, a large amount of gypsum and paper dust is generated, which requires extensive environmental dust collection.
- an object of the present invention is to remove a gypsum and paper easily and cleanly in a very short time when processing a gypsum-paper joined body in which gypsum and paper such as gypsum board waste are joined. Is to provide.
- Another object of the present invention is to provide a method for separating paper from a gypsum-paper joined body using the above-described stripping solution.
- the present inventors can easily remove the paper by removing the paper from the gypsum in the state where the alkali metal salt or ammonium salt of the carboxylic acid is present on the joint surface of the gypsum and paper in the gypsum-paper joined body.
- the present inventors have found a new finding that neat and gypsum can be separated neatly and have completed the present invention.
- a stripping solution used for separating paper from a gypsum-paper joined body made of an aqueous solution of alkali metal salt or ammonium salt of carboxylic acid.
- the carboxylic acid is malonic acid, malic acid, tartaric acid, or citrate,
- a nonionic surfactant or a water-soluble organic solvent is further contained.
- the paper is peeled from the gypsum under the condition that the carboxylic acid metal salt or ammonium salt of carboxylic acid is present on the joint surface between the paper and the gypsum in the gypsum-one-sheet joined body.
- a method for separating paper from a plaster-one-sheet assembly is provided.
- an aqueous solution of a nonionic surfactant or a water-soluble organic solvent Prior to infiltrating the stripping solution into the bonding surface, an aqueous solution of a nonionic surfactant or a water-soluble organic solvent is allowed to penetrate into the bonding surface;
- the stripping solution contains a nonionic surfactant or a water-soluble organic solvent
- the paper is peeled by passing a gypsum-paper joint between the pair of peeling rollers,

- carboxylate is present on the joint surface, and the paper is peeled off from the gypsum in the presence of the strong ruponate, the gypsum and the paper are separated at the joint surface. It can be separated cleanly. That is, the presence of carboxylic acid alkali metal salt or ammonium salt weakens the adhesive strength between paper and gypsum, so that gypsum and paper can be separated cleanly.
- Carboxylate has the effect of improving the solubility of gypsum due to the chelating effect. This effect varies depending on the type of carboxylic acid. For example, an aqueous solution of 3 sodium citrate has the effect of dissolving gypsum in the same mole as 3 sodium citrate dissolved. That is, gypsum dissolves 10 O mm o I / I in trisodium citrate aqueous solution of 1 O O mm o I no I. On the other hand, gypsum dissolves only 2 O mm o I / I in the same molar aqueous solution of citrate.
- Gypsum dissolved in trisodium citrate aqueous solution then reacts with citrate and precipitates as poorly water-soluble calcium citrate. That is, in the present invention, the presence of a carboxylic acid alkali metal salt or ammonium salt on the joint surface of gypsum and paper causes the gypsum to dissolve once, and then the dissolved gypsum reacts to cause poor water solubility. As a result, the entanglement between the paper fibers and the gypsum surface is relieved, the adhesive strength between the gypsum and the paper is significantly reduced, and the paper and gypsum are separated easily and cleanly. This is considered possible.
- paper and gypsum can be separated cleanly.
- the amount of gypsum attached to paper peeled off from gypsum according to the present invention is apparent from the examples described later. In fact, it is virtually zero.
- an alkali metal salt or ammonium salt of a carboxylic acid By immersing an aqueous solution (stripping solution) (hereinafter sometimes simply referred to as a carboxylate) into the gypsum-paper joint by immersing, shearing, spraying, etc. It takes only a few ten minutes, and a few ten seconds at the shortest, so that the gypsum and the paper can be separated from each other. Therefore, it is possible to separate the paper from the gypsum very quickly.
- the carboxylate is present at the bonding interface between paper and gypsum, such an effect continues, for example, once the stripping solution has permeated the bonding interface, Even when left for several hours, the paper can be easily and cleanly separated from the gypsum.
- the stripping solution of the present invention containing a carboxylate can contain a nonionic surfactant or a water-soluble organic solvent, thereby improving the permeability of the stripping solution and shortening the time.
- a sufficient amount of the carboxylate can be present on the joint surface of the gypsum-paper joined body, and the paper can be separated in a shorter time.
- an aqueous solution of a nonionic surfactant or a water-soluble organic solvent is allowed to penetrate the gypsum-one-sheet joined body, thereby increasing the permeability of the stripping solution. Can be increased.
- a water-soluble organic solvent there is also an effect of increasing the drying speed of the secondary separated paper.
- the adhesive strength between gypsum and paper is weakened by the presence of an alkali metal salt or ammonium salt of carboxylic acid on the joint surface. It can be carried out continuously using a peeling roller having a needle-like projection formed on the surface. For example, by passing a gypsum-one-paper assembly between a pair of the peeling rollers, by continuously peeling the paper, the paper can be easily peeled off from the gypsum, and its industrial value is extremely high. high.
- the gypsum recovered by separating the paper from the gypsum board waste material can be reused as two-water gypsum. It is also possible to heat the recovered gypsum to make hemihydrate gypsum or anhydrous gypsum. At this time, since there is no mixed paper dust, gypsum due to carbonization of the paper dust even when processed at a relatively low temperature. There is no discoloration. Furthermore, the separated paper can be reused as waste paper because it has no plaster adhesion and is not damaged by heating. When the separated paper is incinerated, there is an advantage that generation of sulfur oxide (SOX exhaust gas) can be effectively prevented.
- SOX exhaust gas sulfur oxide

- the solubility of calcium carboxylate corresponding to the carboxylate salt is lower than that of an aqueous solution having the same molar concentration. This is preferred because it tends to increase the force ⁇ , the effect of improving the peelability of the paper (shortening the time taken to separate the gypsum and paper, lowering the adhesive strength of the joint surface between gypsum and paper, etc.).
- the carboxylic acid having a smaller molecular weight tends to have a higher penetration rate into the gypsum-one-sheet joined body.
- a stripping solution comprising an aqueous solution of an alkaline metal salt or ammonium salt of carponic acid is prepared by adding, for example, sodium hydroxide to the aqueous solution of the carboxylic acid. It can be prepared by mixing potassium hydroxide or ammonia, or by dissolving the sodium salt, potassium salt or ammonium salt of the above carboxylic acid in water.
- the concentration of the aqueous solution of the carboxylate used as the stripping solution is not particularly limited, and may be appropriately determined within the range in which the carboxylate to be used is dissolved.
- the solubility of the carboxylate considering the operability when used as a stripping solution, the concentration is 0.1 to 5 0% by weight of the carboxylic acid salt, to be particularly 1-3 is 0 mass 0/0 preferable.
- the total carboxylate concentration satisfies the above range.

- the above-mentioned carboxylate is present on the joint surface of the gypsum-one-sheet joined body, and the paper can be separated quickly and cleanly by peeling off the paper.
- the above-described stripping solution is allowed to permeate the joint surface.
- Various methods can be employed as a method for causing the stripping solution to penetrate into the joining surface. For example, (1) using a brush or a roller for painting, supplying the stripping solution to the paper surface, (2) Dipping the gypsum-paper joint into the stripping solution and allowing the stripping solution to penetrate into the joint surface. (3) Supplying the stripping solution to the paper surface by showering or spraying and joining It is possible to adopt a method such as penetration into the surface. [0035]
- the amount of stripping solution used depends on the size and shape of the target gypsum-to-paper joint and the strength rupnate concentration in the stripping solution. An amount that can be present on the joint surface is sufficient. Since the effect of improving the paper separability by such a stripping solution is extremely high, in general, the amount of stripping solution used may be quite small. Specifically, a gypsum-to-paper joint is 0.1 per 1 part by mass. What is necessary is just to set the usage-amount of stripping solution so that the carboxylic acid salt of mass part or more, especially 0.5 mass part or more may be supplied to the gypsum-one-paper joined body. In addition, even if an excessive amount of stripping solution is supplied, the economic efficiency is only impaired. Therefore, the supply amount of the carboxylate to the gypsum-paper joined body may be 2 parts by mass or less. preferable.
- an aqueous solution of a nonionic surfactant or a water-soluble organic solvent may be allowed to permeate the gypsum-one-paper joined body. That is, an aqueous solution of a nonionic surfactant or a water-soluble organic solvent is infiltrated in advance, so that when the stripping solution is supplied thereafter, the stripping solution is quickly applied to the joint surface between gypsum and paper.
