本考案は積み重ねて保管、荷役、搬送されるガ
ラス板間に挟み込まれる合紙に関する。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to interleaf paper that is sandwiched between glass plates that are stacked for storage, handling, and transportation.

ラス板間に合紙を挟み込むようにしている。(Prior art) When storing, handling, or transporting a large number of stacked glass plates, when the glass surface comes into contact with moisture in the air, so-called burns occur, and when the glass plates come into contact with each other or are subjected to impact, they can be damaged. Therefore, a piece of paper has traditionally been inserted between the glass plates.

高く樹脂分も0.5〜1.2重量％程度含有している。 Such interleaf paper is mainly made from old newspapers, etc., from which ink and ink base have been removed, using the fourdrinier method, short wire method, or twin wire method. ) is added (approximately 65 kg to 1000 kg of raw materials). The glass interleaving paper produced by this method mainly has a pH of 4.5 to 5.5 and one surface is smooth, and generally has a high density and contains about 0.5 to 1.2% by weight of resin.

く白い粉を発生する。(Problem to be solved by the invention) The above-mentioned conventional interleaving paper has a large amount of fine fibers in the paper, and the fine fibers have a relatively large amount of adsorption of resin and fat, and as a result, the paper has a large amount of fine fibers. The resin content, etc. of If the resin content in the interleaving paper increases, it will be transferred to the glass surface (formation of paper texture) due to contact with the glass surface, resulting in a decrease in the transparency of the glass. In addition, if there are many fine fibers, the density will be relatively high, and the degree of freedom of fiber expansion and contraction will be reduced when moisture is added, making it more likely to wrinkle and form paper texture (tiger skin) when it comes into contact with the glass surface. . Furthermore, the PH is 4.5
~5.5, chlorine, etc. in the interleaf reacts actively with metals (Na, Fe, Mn, Mg, etc.) appearing on the glass surface, forming a white film on the glass surface. In addition, paper dust easily separates from the interleaf paper, making the glass surface white.
In addition, a large amount of aluminum sulfate transfers to the glass surface, producing white powder.

る。(Function) By reducing the amount of aluminum sulfate added, the fine fibers in the interleaving paper are reduced, and as a result, the resin content in the interleaving paper is reduced, reducing the density of the interleaving paper and increasing the porousness. Further, by reducing the amount of aluminum sulfate added, the pH of the paper is set to 6 to 7, thereby suppressing the chemical reaction and preventing the paper powder from separating into a film. Further, the dislocation of aluminum sulfate crystals is reduced.
（実施例）
以下に本考案の実施例を添付図面に基いて説明
する。(Example) An example of the present invention will be described below based on the accompanying drawings.
第１図は本考案に係る合紙をガラス板間に挟み

状態で架台３上に積層される。 FIG. 1 is a perspective view of a state in which the interleaving paper according to the present invention is sandwiched between glass plates. The glass plates 1 are manufactured by a float method or the like and cut into predetermined dimensions, and each glass plate 1... They are stacked on a pedestal 3 with interleaf paper 2 sandwiched between them.

７となるようにしている。 The interleaf paper 2 is made from deinked pulp, which is obtained by removing ink and ink base from waste newspapers made from ground wood pulp, as the main raw material, and aluminum sulfate is added thereto, and is made by a Fourdrinier method, a short wire method, or a twin wire method. . Here, the amount of aluminum sulfate added is aluminum sulfate per 1000 kg of deinked pulp.
The amount of aluminum sulfate added is significantly reduced compared to the conventional method, and the pH of the interleaf paper 2 to be made is 6 to 35 kg.
I'm trying to make it 7.
また、硫酸アルミニウムの添加量を上記の割合

中の樹油脂分が少なくなる。 In addition, by adjusting the amount of aluminum sulfate added to the above ratio, the amount of fine fibers in the interleaving paper 2 is reduced, and as a result, the density of the interleaving paper 2 becomes coarse and porous, and when moisture is absorbed. Since the degree of freedom of expansion is increased, wrinkles are less likely to occur, and the interleaving paper 2
The resin content inside will decrease.
更にポーラスであることから水分の放散が良く

転移がなくなり、紙肌の白さが減少する。 Furthermore, since it is porous, moisture dissipates better and chemical effects such as burning and paper skin formation are reduced.
In addition, since the amount of aluminum sulfate added was adjusted to the above ratio so that the pH of the interleaf paper 2 was 6 to 7, the chemical reaction on the glass surface was reduced, and the whiteness of the paper surface was reduced. Furthermore, by adjusting the amount of aluminum sulfate added in the above ratio, the aluminum sulfate crystals in the interleaf paper 2 are eliminated, no longer transfer to the glass surface, and the whiteness of the paper surface is reduced.

100％相対湿度の条件下で行つた。(Effect of the invention) Figure 2 is a graph comparing the interleaving paper (PH6-7) according to the present invention and the conventional interleaving paper (PH4.5-5.5) in terms of the number of days elapsed and the white cloudiness. is a graph comparing the interleaving paper according to the present invention and the conventional interleaving paper in terms of the relationship between the number of days elapsed and transparent skin. Both experiments were performed at 60℃ and 98~
It was carried out under conditions of 100% relative humidity.
これら第２図及び第３図から明らかなように、
合紙のPHを６〜７とすることにより、PH５又はPH

By setting the PH of the paper to 6 to 7, PH5 or PH
It can be seen that compared to around 8, there is a significant improvement in white cloudiness and transparent skin.
