Reference numeral 1 denotes a humidity control panel for wall finishing, wherein the humidity control panel 1 for wall finishing is a hard fiber panel 11 and a soft fiber panel 12 bonded by an adhesive, and reference numeral 2 denotes a ceiling finish. It shows humidity control panel.

The wall finishing humidity control panel (1) and the ceiling finishing humidity control panel (2) is composed of wood-based fibers to absorb moisture when there is a lot of moisture in the air and to release the moisture absorbed when the moisture is low It has a function to control humidity.

In the case of the humidity control panel 1 for wall finishing, the hard fiber panel 11 is constructed to be exposed to the inner wall surface of the storage cabinet, and the rear side of the soft fiber panel 12 is made of a water-resistant plywood board on which both sides are bonded with aluminum cardboard. The impervious panel 3 is bonded to be constructed so as to completely block the penetration of moisture from the outside into the storage.

The air flow passage 11a formed in the hard fiber panel 11 constituting the wall finishing humidity control panel 1 allows the air inside the cabinet to flow while the air flows through the hard fiber panel 11 and the soft fiber panel ( 12) to allow the moisture in the air to be absorbed or released to the hard and soft fiber panel to control the humidity, so that the air flow path (11a) has a horizontal state so that the flow of air smoothly appears. Also, both parts of the air flow passage 11a are formed so that a predetermined interval S is formed to freely move in and out of the air.

The ceiling finishing humidity control panel (2) is to be constructed by sandwiching the concave portion 21 and the projections 22 formed on both edges symmetrically to each other, the assembly part of the ceiling finishing humidity control panel (2) By allowing a very narrow gap D to be formed, the moisture absorbs or discharges the gap D smoothly, and also penetrates the outside of the humidity control panel 2 for finishing the ceiling. The impervious panel 3 is installed to block the.

The humidity control panel (1) for wall finishing and the humidity control panel (2) for ceiling finishing are all molded by the same manufacturing method using the wood-based fiber as a raw material, the manufacturing method for this will be described as follows.

<Crushing process>

In this process, the crushed particles are shredded into 3cm, 2cm, and 0.5cm size by using shredder after collecting the sawdust generated by the planer or sawdust caused by the planer when crushing the remaining pine wood. It is a process.

<Sea Island Process>

This process is to decompose into fibrous by supplying water to the crushed particles that have undergone the crushing process to maintain a proper moisture content and applying pressure at a high temperature of 160 ~ 190 ℃.

<Adhesive coating process>

This process is a step of applying a resin adhesive (urea resin) by introducing the fiber decomposed in the sea island process to the brew line, the resin adhesive is sprayed on the brow line in the liquid phase to be bonded to the fiber.

<Drying process>

The present step is a step of drying the fiber after the adhesive coating step into the dryer to dry, so that the water content of the fiber is about 8 to 13%.

<Mold injection process>

This process is a step of injecting the fiber dried in the drying step into the molding mold using air, the fiber injected into the molding mold is laminated to a predetermined thick thickness with a very large voids. .

<Differentiation process>

This process is a process of reducing the stacking height of fibrous mats that are injected and laminated in a molding die by trimming a plurality of fibers stacked thickly in a mat in a mold in a mold injection process as a press.

<Molding process>

This process is a process of compressing and finishing the fibrous mat, which has been squeezed to some extent in the finishing process, at a pressure of 20 to 30 Kg / cm ² under a high temperature of 150 to 170 ° C. to a thickness required by the humidity control panel. The humidity control panel for wall finishing and the humidity control panel for ceiling finishing are determined according to the thickness and density of the panel.

That is, in the case of the hard fiber panel constituting the humidity control panel for wall finishing, the thickness is 8 to 10 mm and the density is about 680 to 720 kg / m ³ , and the soft fiber panel is 14 to 16 mm in thickness and the density is It is pressed to be about 330 ~ 370kg / m ³ , the humidity control panel for ceiling finishing is pressed to be ¹⁴ ~ 16mm thick, density 630 ~ 670kg / m ³ .

<Cooling process>

In this process, the resin adhesive applied to the fibers of each of the humidity control panels heat-compressed to have the thickness and density required in the molding process is not completely cured, so it is put into a cooler for a predetermined time (about 30 to 40 minutes). It is a process of completely hardening a resin adhesive by cooling.

Cutting and polishing process

This process is a process of cutting each humidity panel that has undergone the cooling process to a certain standard and then polishing and removing the surface, wherein the surface of each humidity panel that has passed the cooling process is preliminarily cured by a cooling action, so that the resin adhesive The binding force of the weak state is removed by polishing work to make a humidity pad with excellent bonding strength.

After inspecting and screening the humidity control panel for wall finishing and ceiling finishing humidity control panel manufactured by the above process, it is stored in the storage warehouse and shipped to the manufacturing site of the storage warehouse, where the humidity control panel for wall finishing (1) In the case of the surface of the hard fiber panel 11, after applying a melamine resin adhesive, and then glued special paper, the back of the grooved to form a plurality of air flow passage (11a) and then the soft fiber panel 12 It is to build a wall of the storage by joining with, in the case of the humidity control panel (2) for finishing the ceiling is to adhere the special paper on both sides to build the ceiling.

According to the present invention as described above, each of the humidity panels for building the wall and ceiling of the cultural heritage store is made of wood-based fiber as a raw material, so it is superior in humidity control function compared to that made of wood, and the effect of suppressing the daily variation of humidity small and gentle. In addition, even if the air conditioner is stopped for a long time, the humidity inside the cabinet can be kept constant humidity, which can reduce the operating cost of the air conditioner. It is a useful invention that has a secondary effect such as contributing to the recycling aspect of the resource by manufacturing.
