Description

Control method of moisture content in the production process of solid wood furniture

Technical field:

The invention relates to the technical field of methods for controlling moisture content of wood, in particular to a method for controlling moisture content in the production process of solid wood furniture.

Background technique:

When wood is placed in humid air, it will absorb water vapor in the air and increase the moisture content of wood. This phenomenon is called hygroscopicity; on the contrary, if wood with high moisture content is placed in low humidity air, the wood will lose Wet and reduce the moisture content of wood, this phenomenon is called dehumidification. The process of moisture absorption and dehumidification is essentially a process in which the moisture content of wood gradually transitions to be consistent with the equilibrium moisture content of the environment. In the production process of wooden furniture, wood is often affected by the production environment, and its moisture content is difficult to control, so that the moisture content of the manufactured wooden furniture does not meet the requirements, which ultimately affects the quality of wooden furniture. For example, due to climate factors in the United States and air-conditioning facilities in the home environment, the moisture content of wooden furniture in the home environment is mostly between 6% and 8%. Therefore, furniture sold in China to the United States requires that the moisture content of wood must be controlled at 6%. ~8% range, while the annual average wood moisture content in most parts of China is 11% to 16%, especially in Guangdong, the annual average wood moisture content is as high as 15.9%. To produce solid wood furniture in such a humid environment, if there is no The special moisture content control method in the manufacturing process, even if the wood raw material is dried to reduce its moisture content to below 8% before starting to manufacture furniture, but after the complicated processing procedures in the production workshop and exposure to the environment of high equilibrium moisture content, with time With the increase of time, the moisture content of wood also increases. Often, the moisture content of wood has risen to more than 10% between furniture coatings. In this way, if the manufactured furniture is sold to drier areas in the United States, the wood will dehumidify and shrink, resulting in cracks in the furniture, which not only affects the quality of the furniture, but also easily leads to many transaction claims.

The existing technology generally uses dehumidification equipment to control the moisture content of wood used to produce solid wood furniture, such as microwave treatment dehumidification equipment, which uses the principle of microwave heating to control the moisture content of wood; there are also drying and heating equipment to control the moisture content of wood by controlling the drying and heating equipment. The temperature and humidity of the wood storage environment to control the moisture content of the wood. However, these dehumidification equipment or drying and heating equipment are only used in individual stages such as the material preparation stage in the production process of solid wood furniture, and are not used in the entire production process of solid wood furniture. Requirements, but in the whole production process of solid wood furniture, the moisture content of wood is still affected by the equilibrium moisture content of the production environment, which cannot make the moisture content of wood meet the requirements of each stage in the production process of solid wood furniture.

Step B, drying the raw materials in a drying kiln so that the moisture content of the wood is 6% to 8%, and entering step C;

Step C, put the raw materials into the raw material storage room, and control the temperature in the raw material storage room to control the equilibrium moisture content in the raw material storage room to 6% to 8%, so that the wood moisture content is 6% to 8%. %;

This step one is actually the control of the moisture content of the raw wood before material preparation, that is, the use of the raw material warehouse to control the initial moisture content of the solid wood furniture materials. This step is particularly important. Only wood with a moisture content that meets the requirements can be used in Effective control in subsequent processing.

Step 2, prepare the material, and control the moisture content of the wood prepared for the material to be 6% to 8%, specifically:

Step D, picking materials from the health care room of the raw material warehouse, the moisture content of the wood being picked is 6% to 8%;

The third step is the fine processing process of solid wood furniture, including the process of assembly, assembly, painting and packaging. Since the wood may take a long time in a certain process during the fine processing process, the wood in this process The moisture content of the wood is easily affected by the equilibrium moisture content of the production environment and changes, which may cause the moisture content of the wood to fail to meet the set requirements. This requires that in the fine processing process of solid wood furniture, corresponding health care rooms should be set up in different processes, such as bed assembly health care rooms, assembly health care rooms, and frame assembly health care rooms, so that the moisture content of the wood can be adjusted after the corresponding processes are completed. Then control to keep the moisture content of the wood within the set range. When entering the painting process, the wood should be sprayed with primer immediately, so that the paint film will form a protective film between the furniture and the atmosphere, reducing the wood's absorption of air moisture.

In the first embodiment, the moisture content of the wood is controlled in the range of 6% to 8%, which is mainly applicable to the production process of solid wood furniture sold in the United States and other places.

Example 3, the difference from Example 1 is that in the production process of all solid wood furniture, the moisture content of the wood is controlled at 11% in Step 1, Step 2 and Step 3, and in Step A of Step 1, the moisture content of the raw materials is detected For wood moisture content, if the wood moisture content is less than or equal to 11%, go to step C; if the wood moisture content is >11%, go to step B.

Embodiment 4 is different from Embodiment 1 in that in the production process of all solid wood furniture, step 1, step 2 and step 3 all control the moisture content of wood in the range of 8% to 10%, wherein step A of step 1 , when detecting the wood moisture content of the raw material, if the wood moisture content is ≤ 10%, then enter step C; if the wood moisture content > 10%, then enter step B.

Embodiment 5 is different from Embodiment 1 in that in the production process of all solid wood furniture, step 1, step 2 and step 3 all control the moisture content of wood in the range of 10% to 12%, wherein step A of step 1 , when detecting the wood moisture content of the raw material, if the wood moisture content is ≤ 12%, then enter step C; if the wood moisture content > 12%, then enter step B.

Embodiment 6, the difference from Embodiment 1 is that in the production process of all solid wood furniture, step 1, step 2 and step 3 all control the wood moisture content in the range of 12% to 13%, wherein step A of step 1 , when detecting the wood moisture content of the raw material, if the wood moisture content is ≤ 13%, then enter step C; if the wood moisture content > 13%, then enter step B.

The above different examples illustrate that in the production process of solid wood furniture, the control range of the corresponding wood moisture content should be determined according to the environmental balance moisture content of the area where the solid wood furniture is sold, so that the solid wood furniture can be suitable for the area where the solid wood furniture is sold. application.

The raw material warehouse health care room, material preparation health care room, central parts warehouse health care room, bed assembly health care room, assembly health care room and frame assembly health care room described in the present invention are all sealed health care rooms during work. The health care rooms are provided with steam pipes, Dry-bulb thermometer and wet-bulb thermometer, high-temperature steam supplied from the boiler room flows in the steam pipe, by judging the temperature difference between the dry-bulb thermometer and the wet-bulb thermometer, and then controlling the high-temperature steam flow in the steam pipe according to the temperature difference to control the health preservation The temperature in the room is used to control the equilibrium moisture content in the health care room, thereby controlling the moisture content of the wood. Each health care room is in charge of a dedicated operator. Every two hours, it is necessary to check whether the equilibrium moisture content in the health care room is within the set standard range of the health care room. The operator reads the dry bulb thermometer and humidity in the health care room. According to the readings of the bulb thermometer, calculate the temperature difference between the dry bulb thermometer and the wet bulb thermometer, and find out the equilibrium moisture content of the health care room at that time according to the comparison table used to guide the operation. If the equilibrium moisture content is too high, add steam The high-temperature steam flow in the pipe will properly increase the temperature in the health care room. If the equilibrium moisture content is too low, the temperature in the health care room will be appropriately lowered by reducing the high-temperature steam flow in the steam pipe. In this way, by monitoring the temperature in the health care room at any time The balanced moisture content ensures that the moisture content of wood in each production process can be maintained within the set range. Below, on the basis of Embodiment 1, several examples are given to illustrate the specific control process of the equilibrium moisture content in the health care room:

Example 1, the reading of the dry-bulb thermometer is 38°C, the reading of the wet-bulb thermometer is 28°C, and the calculated temperature difference is 10°C. According to the comparison table, the equilibrium moisture content in the health care room at this time is 8.1%, which is higher than For the set equilibrium moisture content, it is necessary to increase the temperature in the health care room to 46°C by increasing the high-temperature steam flow in the steam pipe.

Example 2, the reading of the dry bulb thermometer is 38°C, the reading of the wet bulb thermometer is 24°C, and the calculated temperature difference is 14°C. According to the comparison table, the equilibrium moisture content in the health care room at this time is 5.7%, which is lower than For the set equilibrium moisture content, it is necessary to lower the temperature in the health care room to 32°C by reducing the high-temperature steam flow in the steam pipe.

Example 3, the reading of the dry bulb thermometer is 39°C, the reading of the wet bulb thermometer is 27°C, and the calculated temperature difference is 12°C. According to the comparison table, the equilibrium moisture content in the health care room at this time is 6.9%, which is at the design level. A certain range of equilibrium moisture content without changing the temperature in the health care room.

Among them, the comparison table is an experience table obtained in the actual control process, which can be set according to different situations, as long as it can achieve the purpose of controlling the moisture content. The health care rooms of the present invention, such as raw material warehouse health care room, material preparation health care room, central parts warehouse health care room, bed assembly health care room, assembly health care room and frame assembly health care room, are designed according to the moisture absorption and dehumidification principle of wood. In the wood storage area, control and maintain its environmental equilibrium moisture content in the range of 6% to 8%. The moisture content of the wood parts being processed is 6% to 8% when they are taken out of the raw material warehouse. The wood parts will absorb air during the processing of the workshop. The water vapor in the wood will gradually increase the moisture content of the wood. If the wood parts are stored in the health care room with the equilibrium moisture content set at 6% to 8% after each processing step, the moisture absorption of the wood during the previous processing will be reduced. Moisture can be dehumidified in the wellness room, keeping the moisture content of the wood parts below 8%.

The present invention sets health care rooms for controlling the moisture content of wood in different production processes of solid wood furniture, such as raw material warehouse health care room, material preparation health care room, central parts warehouse health care room, bed assembly health care room, assembly health care room and frame Assemble the health care room, so that the wood can always be kept within the set moisture content range during the complicated processing process. Finally, after the furniture painting process is completed, the moisture content of the wood can be controlled to meet the requirements of the entire solid wood furniture production process. Within the range of moisture content, so as to effectively ensure the quality of furniture.

The above are only preferred embodiments of the present invention, so all equivalent changes or modifications made according to the structure, features and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
