The role of humidity, in this way, has the function of regulating humidity.

When the above-mentioned humidity-controlling board (1) for interior wall decoration is installed, the part of the hard fiberboard (11) is exposed on the inner wall of the collection hall, and the inner side of the soft fiberboard (12) is bonded with the moisture-proof board (3). Board (3) is a water-resistant plywood with aluminum board paper bonded on both sides. In this way, the moisture from the outside cannot penetrate into the interior of the collection at all.

An air flow passage (11a) is formed on the hard fiberboard (11) constituting the humidity-controlling board (1) for interior wall decoration. 11) In contact with the soft fiberboard (12), the moisture in the air is absorbed or released by the hard and soft fiberboard, thereby adjusting the humidity. In order to make the air circulation smooth, the air flow path (11a) is carried out horizontally Construction, in addition, the side portions of the air flow path (11a) are formed to form a certain interval (S) so that the air can freely flow in and out.

The board (2) for ceiling decoration forms mutually symmetrical recesses (21) and protrusions (22) on its two side edges, and construction is carried out by inserting and assembling the recesses (21) and protrusions (22). A very narrow gap (D) is also formed in the assembled part of the humidity-controlling plate (2), and moisture is smoothly absorbed or released through the gap (D), and the outside (upper side) of the humidity-controlling plate (2) for ceiling decoration Also be provided with the moistureproof plate (3) of blocking moisture.

The humidity-regulating panel (1) for interior wall decoration and the humidity-regulating panel (2) for ceiling decoration are all formed by the same manufacturing method with wood fiber as raw material. Each step of this production method will be described below. 〔Crushing process〕

In this process, the remaining wood chips, shavings, sawdust, etc. after pine processing are collected and broken into broken particles of various sizes of 3cm, 2cm, and 0.5cm. 〔Fibrillating process〕

In this step, water is supplied to the particles crushed in the above-mentioned crushing step to maintain an appropriate moisture content, and then high temperature pressure of 160 to 190° C. is applied to decompose the fibers. 〔Adhesive coating process〕

In this step, the fiber decomposed in the above-mentioned defibrating step is put into a blowing line, and a resin adhesive (urea resin) is applied. The resin adhesive is sprayed by a blower wire in a liquid state and adhered to the fiber. 〔Drying process〕

In this step, the fibers passed through the above-mentioned adhesive coating step are put into a drier and dried to such an extent that the moisture content of the fibers becomes 8 to 13%. 〔Injection mold process〕

In this step, the fibers dried in the above-mentioned drying step are injected into a molding die in a mat state using air, and the fibers injected into the molding die are laminated to a predetermined thickness with large voids. 〔Anvil beating process〕

In this process, the fibrous material that was thickly laminated in the molding die in the form of a block in the above-mentioned injection molding process is punched with a press anvil several times, so that the laminated fibrous pads in the molding die are laminated. Thickness decreases. 〔Forming process〕

In this process, at a high temperature of 150-170 ° C, with a pressure of 20-30 kg/cm ² , the fibrous pads that have been anviled to a certain extent by the above-mentioned anvil beating process are heated and crimped, and the humidity-regulating plate is compressed. to the required thickness.

The thickness and density of the humidity-controlling board for interior wall decoration or the humidity-controlling board for ceiling decoration are compressed and formed by this process, that is, the hard fiberboard constituting the humidity-controlling board for interior wall decoration is compressed to a thickness of 8 to 10 cm, and the density It is 680～730kg/cm ³ . The soft fiberboard is compressed to a thickness of 14-16cm and a density of 630-670kg/cm ³ . 〔Cooling process〕

In this process, since the resin adhesive applied to the fibrous material of each humidity-conditioning panel that has been heat-compressed into the required thickness and density by the above-mentioned forming process is not completely hardened, it is put into a cooling machine and cooled for a certain period of time. time (about 30-40 minutes), the resin adhesive is completely hardened. 〔Cutting and grinding process〕

In this step, each humidity-controlling plate that has passed through the above-mentioned cooling step is cut to a certain size, and its surface is ground. The surfaces of the humidity-controlling panels that have passed through the above-mentioned cooling process harden early due to the cooling effect, leading to weakening of the adhesive force of the resin adhesive, and the humidity-controlling panels with strong adhesive force are finally produced by grinding.

The humidity-controlling panels for interior walls and ceilings manufactured through the above-mentioned processes are stored in a warehouse after being inspected and sorted by category, and then transported to the construction site of the collection hall. At this time, for the humidity-controlling board (1) for interior wall decoration, after the melamine resin is coated on the surface of the hard fiberboard (11), the decorative board is bonded, and the groove is made on the back surface of the hard fiberboard (11). Grooves are processed to form multiple air flow passages (11a) on the surface, and then bonded with soft fiberboards (12) to construct the inner wall of the collection hall. As for the humidity-controlling board (2) for the ceiling, decorative boards are bonded on both sides to form the ceiling.

As mentioned above, according to the present invention, the humidity-regulating panels and the like constituting the inner walls and ceiling of the cultural relics collection hall are made of wood fibers, and compared with those made of logs, they have a better humidity-regulating function and can keep the humidity constant. Diurnal ranges are low, making humidity changes moderate. Even if the air conditioner is stopped for a long time, the humidity in the collection hall does not change, and a constant humidity state can be maintained, so the operating cost of the air conditioner can be saved. In addition, because it is manufactured by using leftover wood chips, shavings, sawdust, etc. after log processing, resources can be reused.
