Abstract

PURPOSE: A method for manufacturing of wood for wood crafts is provided which maintains beautiful carving surface and neither deforms nor cracks articles of wood crafts so that characteristics of wood-carvings are manifested to the utmost, and enables delicate carving so that accessories as well as wood-carvings can be produced. CONSTITUTION: The method for manufacturing of wood for wood crafts comprises first step of sawing the cut material wood into a square bar having about 3 to 5 cm of width and height and about 90 to 100 cm of length by cutting material wood such as jujube tree and Betula Schmidtii; drying the wood in the drying chamber at a temperature of 70 to 80 deg.C for 10 to 30 days until water content becomes 19 to 30% after putting the prepared wood into a drying chamber; heating and pressing the wood for 30 to 60 minutes in the press until wood is compressed to a half thickness of the original wood by applying a pressure of 20 to 250 kg/cm¬2 to wood as maintaining temperature of the hot plates as 130 deg.C after putting the dried wood into a space between hot plates of a press with a heater in which water and steam are alternately circulated; cooling the wood in the compressed state to an ordinary temperature for about 40 minutes by removing steam supplied to the hot plates and circulating cooling water through the hot plates after finishing heating and pressing; and cutting the cooled wood to a certain size and packing the wood for wood crafts cut to a certain size after taking out the cooled wood from the press.

Description

Method for manufacturing wood for woodworking {METHOD FOR MANUFACTURING OF WOOD FOR WOODWORK}

The present invention relates to a method for producing wood for producing various wood craft products such as wood tension, wood beads, wood beads, wood amulets, wood ornaments (accessories).

Woodworking is a wide range of types, but in the present invention is to supply wood used as a material in the manufacture of small items such as seals, beads, beads, charms, such as jujube or birch wood to process wood It aims to produce beautiful woodwork products made of materials of suitable strength and durability.

Conventionally, it is common to use natural dry wood in the shade to manufacture such a material.

However, the wood produced by natural drying has a problem that it is not suitable for wood crafts because of the lack of stability due to high stretch rate, it is not possible to make a high-quality wood craft products.

The present invention was developed in order to solve the above conventional drawbacks and will be described in more detail as follows.

First step (preparation of tree)

Cut wood, such as jujube or birch, and cut them into pieces of 3-5cm long and 90-100cm long.

2nd process (1st drying)

The wood prepared in the first step is placed in a drying chamber at 70-80 ° C. and dried to have a water content of 19-30% over 10-30 days.

3rd process

When the wood dried in the second process is placed between hot plates equipped with a heating device to alternately circulate water and steam, and the hot plate temperature is maintained at 130 ° C., the pressure is 200-250kg / cm ² and the thickness of the wood becomes about 2.5cm. Heat and press for 30-60 minutes until the end of the heat press, extract the steam supplied to the hot plate, circulate the cold water and cool it in the compressed state for about 40 minutes until it reaches room temperature.

4th process

Take out the cooled material, cut it to a certain size and pack it.

The processed wood is used as a wood for wood crafts such as tensile material, dyeing material, short addressing material, key ring, and accessories. It is hardened and stabilized so that no cracking occurs and elasticity is not easily deformed.

Therefore, making wood carving products has the advantage of maintaining beautiful carving surface and not easily deforming at the same time. It is not cracked, so it can maximize the characteristics of wood carving products and enables delicate carvings. Of course, it is also possible to satisfy the production of wood carving products such as seals, beads, and beers.

Claims (1)

Lubricate wood such as jujube or birch with a certain size of 3-5cm in length and 90-100cm in length, and put it in a drying room and dry it to less than 19-30% of water content at 70-80 ℃ for 10-30 days. Step and place the dried lumber between the hotplate, which alternately circulates water and steam, and apply pressure of 200-250kg / cm ^{2 with} a heat of 130 ° C. over 30-60 minutes until the thickness of the lumber is compressed to half. A method of manufacturing wood for woodworking obtained by sequentially performing a step of hot pressing and a step of removing steam in a hot plate and circulating cold water to cool to room temperature for about 40 minutes.
