However, in the first compression step, a specific pressure must be applied to the compression while maintaining the natural pattern of the plant intact. If the stem of the plant, such as the reed stem, vine stem is soaked in water, if the pressure is not accurate, there is a problem that can not be processed due to the death or crushed like pulp. Appropriate pressure for compressing while maintaining the natural pattern of the plant is 0.5bar ~ 1bar.

Next, 2.5 kg of polyester 800 cps to 1600 cps low density resin and 7 kg of 8000 to 11000 cps high density resin were dissolved in 10 L of toluene, 3 L of xylene and 5 L of MEK (Methyl Ethyl Ketone) to dilute the first resin solution (coating solution). Make After putting the stems of plants such as the first pressing (0.5 bar to 1 bar) and the first dried reed stems and vine stems into the first resin solution, the first resin solution is sufficiently infiltrated into the stems for 2-3 hours. Allow precipitation. Thereafter, the stem is completely dried and subjected to a second pressing step using a pressing roller as shown in FIG. 3.

In the second compression, a pressure of 3 to 4 bar is applied to increase the pressure to make the stem of the plant very flat. Even if the pressure is increased, the polyester resin is infiltrated, so that the natural material is not damaged and it is hard and flexible. 4 shows the stem of the plant subjected to the second compression process.

Then, a second resin solution produced by mixing 5 kg of polyester 800 cps to 1600 cps low density resin, 2 kg of 8000 to 11000 cps high density resin and 300 g of antioxidant was mixed with a solvent of 10 l of toluene, 3 l of xylene, and 5 l of methyl ethyl ketone (MEK). After 25 to 35 minutes (preferably 30 minutes) of the stem of the plant, such as the reed stem and vine stem, which has been pressed into the adhesive, it is allowed to dry using a hot air dryer and to be able to perform the design work. .
