Description

Method of manufacturing korean paper board

The present invention relates to a method for manufacturing Hanji Baekgol, and relates to a method for manufacturing Hanji Baekgol, which can form a thick cardboard in the form of a board using Hanji.

Korean traditional Korean paper is made from perennial vegetation, Dak tree, which has long been a mainstay of paper products in our lives, but after the introduction of high productivity Yangji, its scope of application has narrowed despite its excellent performance. It is limited to finishing papers.

In particular, in the case of Hanji crafts, one of the paper crafts is a skeleton that is made of thick paper in the form of a hard board, and Hanji is made by attaching it to the surface of the paper, but warpage occurs easily due to the difference in tension between the paper and the paper. In addition, in the case of the hard paper paper type, there is a problem in that the comparatively low compressive strength lowers the durability of the product.

The present invention was devised to improve the above problems, and an object of the present invention is to provide a method for manufacturing a white paper bone, which can produce a white paper board having a thickness of 2 millimeters or more by using paper.

Hanjibaekgol production method according to the present invention to achieve the above object is a. Stacking five to six wetlands formed by using a molding frame from the mulberry fibers extracted from the mulberry; I. Pressure drying the stacked wetlands to form a lamination; All. It includes; bonding the plurality of sheets of paper with a natural adhesive to form a white bone thickness of 2 to 6mm.

Preferably, in the autumn step, the wetlands are stacked to cross each other with the wet fiber fiber direction in which the wet direction of the fiber is stacked adjacent to each other.

In addition, the wetlands are laminated with the six sheets in the step, the step B is performed for about 4 to 5 minutes in a heating plate maintained at 80 to 90 ℃, after the multi-step the golgol 60% relative humidity at 20 ℃ Humidity treatment step of storing for 1 month to 2 months in the moisturizing room maintained as; further comprises.

According to the method of manufacturing Hanji Baekgol according to the present invention, the Baekgol having a thickness of 2 millimeters or more can be manufactured using only Hanji, which can be utilized for the production of Hanji crafts, and the occurrence of distortion during the production of crafts is suppressed because Baekgol and Hanji are made of the same material. It also offers the advantage of increasing durability.

Hereinafter, with reference to the accompanying drawings will be described in more detail the manufacturing method of hanji white bone according to a preferred embodiment of the present invention.

1 is a process chart showing the manufacturing process of Hanji Baekgol in accordance with the present invention, Figure 2 is a diagram showing the process of manufacturing Hanji Baekgol of FIG.

First, the wetland (100a to 100f) is formed by using a mold from the medicinal duct fibers extracted from the mulberry (step 10).

Here, the wetlands 100a to 100f refer to grass paper formed using a molding die (not shown) in the form of a screen, and the manufacturing process may be formed by a known method. In other words, the mulberry is immersed in water, peeled off after being soaked, boiled, then dissolved through a confession process, and added to the mulberry, then loosened in water and formed using a screen-forming mold. The wetland (100a to 100f) is formed in a form in which the direction of the mulch fibers are aligned in one direction by water flow by shaking the mold in one direction in the wetland forming process while floating the fibrous fibers adhered to the mold.

The wetlands 100a to 100f thus prepared are usually about 0.3 to 0.4 mm thick and have a water content of 90% or more.

Thereafter, the wetlands 100a to 100f manufactured are preferably stacked in an even number of 5 to 6 sheets, preferably in order to suppress curl generation.

To this end, six sheets of the wetlands 100a to 100f are stacked on each other to form a paper 110 (step 20).

At this time, the wetlands (100a to 100f) are mutually stacked so as to cross each other with the fiber direction of the wet fiber is stacked adjacent to the direction of the mulberry fiber.

Next, the laminated paper 110 in which the six wetlands 100a to 100f are stacked is compressed (step 30) and dried (step 40).

The pressing process may be performed using a press 200 or a pressure roller, and the pressing force may be appropriately applied within a range not to damage the wetland because there is an inherent bonding force between the mulberry fibers forming the wetland.

In addition, drying is performed for about 4 to 5 minutes in the heating plate 300 is maintained at 80 to 90 ℃. Pressurization and drying may be performed simultaneously.

Thereafter, the plurality of sheets of paper 110 are bonded to each other with a natural adhesive 120 to form a white bone having a thickness of 2 to 6 mm (step 50).

As the adhesive 120, a natural adhesive is applied, and preferably, an adhesive paste made of any one of wheat flour, old potato, and glutinous rice is applied.

Preferably, it is pressurized and heated secondly using a thermocompressor capable of simultaneously applying heat and pressure in a state of being bonded with an adhesive.

Next, the prepared white bone is subjected to a humidity treatment step of storing for 1 month to 2 months in a moisturizing room maintained at 60% relative humidity at 20 ° C (step 60).

During the humidification process, the white bone improves its ability to absorb and release moisture, thus suppressing the lifting and peeling of moisture, thereby increasing long-term preservation and durability.
