What are the production processes of wooden handicrafts?

Logs from 100-300 primeval forests in Southeast Asia are harvested in September-65438+February (autumn and winter) every year, then naturally dried on the log growth line, pruned in March-September every other year, and then transported to the processing site.

Square wood molding:

Square wood modeling is very important in the production of pure solid wood furniture. In order to improve the bending properties of wood and increase plastic deformation, it is necessary to soften it before bending. After hydrothermal treatment, part of hemicellulose is easy to decompose and dissolve into liquid state, and the free hydroxyl group on the amorphous region of cellulose molecular chain absorbs water, which makes the water film in the cellulose gap thicker, the intermolecular distance increases, and the attraction decreases, which is convenient for relative sliding under the action of external force.

Insufficient cooking leads to poor plasticization, which is easy to cause damage under severe bending; Excessive cooking will reduce the tensile strength and compressive strength along the grain. Kontnan had done experiments in the temperature range of 19 1℃-200℃, which proved that the compressive strength of wood along grain increased with the decrease of temperature. Due to excessive cooking, the compressive strength along the grain decreases, and it will be difficult for the square wood to bear the compressive deformation produced by the end face when bending.

drying process

1. Manual drying: the wood is sealed in a steam drying chamber, and the water is evaporated by steam to dry the wood. (depending on the size and thickness of wood, for example, the drying time of 4cm board usually takes one week), the highest drying degree can make the moisture content of wood only reach 3%, but the wood after high temperature evaporation is fragile, loses toughness and is easy to be damaged, which is not conducive to carving furniture. Under normal circumstances, the dryness of logs should be kept at about 30% moisture content.

2. Natural drying: classify the wood and put it in a ventilated place (board, square or log), and put it in piles. The bottom of the stake is about 60cm from the ground, and there is a gap in the middle, which makes the air circulate and take away the water, and the wood gradually dries. Natural drying usually takes several years or months to meet certain drying requirements.

Elaborate:

Today's woodcarving constantly innovates on the basis of comprehensively inheriting fine traditions and unique styles, and moves towards domestic and foreign markets, mainly as follows:

1, with stronger decorative flavor;

2. The distinct integrity is more prominent;

3. The combination of practicality and sculpture is more harmonious;

4. The subject matter is richer and more applicable.

The main series of products are finely carved with world-famous wood, and incorporate various carving techniques such as flat knife method, round knife method, relief, shallow carving, hollow carving, through carving and through carving, which fully embodies the long and profound culture of China. Every piece of carved furniture is a work of art, and the thinking and cultural connotation of the carved master are integrated into it. Nowadays, hand-carved furniture and high-grade solid wood furniture are favored by consumers, not only because of the artistic beauty of carving, but also because of the environmental protection characteristics of hand-carved furniture and solid wood furniture, which are truly healthy and environmentally friendly furniture.

Polishing:

Furniture polishing is to make the surface of furniture smooth. From coarse to fine, it has to be sanded with 12 sandpaper. Every polisher must thoroughly polish the traces left by the last one, and finally polish the furniture surface with the finest sandpaper. This is a purely manual process, and it is also an important technological link of handmade furniture. 12 polishing, to be exact, 12 pieces of different types of sandpaper are used to polish furniture. These different types of 12 sandpaper also have their own division of labor in the process of furniture polishing. For example, 120~600 sandpaper is used to polish the basic appearance of furniture, 600~ 1500 sandpaper is used to polish the details of furniture, and 1500~2500 sandpaper is used to make furniture more charming. In this step, when polishing the corners of the object, you should use appropriate force, and the action should be light, and you must maintain the original circular or square outline.

Painting:

Brand series products are all made of natural raw lacquer, which is painted by experienced masters. This is the last major process of handmade furniture and hand-carved furniture. Natural raw lacquer, also known as national lacquer, raw lacquer, earth lacquer, wood lacquer, lacquer, painting, etc. , a kind of high-quality natural paint, comes from virgin forest and natural lacquer tree. It is a natural lacquer tree sap artificially cut from lacquer tree. The natural lacquer tree sap mainly contains urushiol, resin and water, and has the functions of corrosion resistance, strong acid resistance, alkali resistance, moisture-proof insulation, high temperature resistance and dirt resistance. Natural raw lacquer also has the world-recognized reputation of "king of coatings".
