Description

Technical Field

[0001] The invention relates to the field of interior decoration materials, and in particular to a non-deformed ultra-long extremely energy-efficient ecological board made of solid wood of Chinese fir that has been dehydrated and degreased and has a production process thereof. Background Art

[0002] Fragrant fir is a high-quality furniture material with a natural wood fragrance. It has many beneficial effects on the human body. Fragrant fir is a kind of fir tree with clear texture, uniform structure, light and soft material, easy to dry, small shrinkage, no warping and cracking, good durability, easy processing, good gluing performance, and various colors, mainly light yellow, but also light reddish brown, etc. Fragrant fir has natural insect and anti-corrosion properties. This is because its wood contains ingredients such as cedar alcohol, which can effectively resist the erosion of insect pests and mold. Fragrant fir is widely used in furniture manufacturing, interior decoration, building materials and other fields. In furniture manufacturing, fragrant fir can be used to make tables, chairs, beds, cabinets, etc.; in interior decoration, it can be used to make floors, wall panels, ceilings, etc.; in building materials, it can be used to make roofs, window frames, doors, etc.

[0003] In decoration practice, the deformation degree of ordinary fir solid wood ecological board is relatively large, which causes the surface to crack and the cabinet doors cannot be closed flat. According to the climate changes throughout the year, the deformation degree of the board also changes constantly, resulting in constant disputes between suppliers and users. In serious cases, the board has to be dismantled and reinstalled, causing huge economic losses. Summary of the invention

[0004] The main purpose of the present invention is to provide a non-deformed ultra-long extremely energy-efficient ecological board made of solid wood of Chinese fir, which can be dehydrated and degreased and whose production process is also provided, and can effectively solve the problems in the background technology.

[0005] To achieve the above object, the technical solution adopted by the present invention is:

[0006] A dehydrated and degreased non-deformed ultra-long extremely energy-efficient ecological board made of solid fir wood comprises fir wood.

[0007] Preferably, the annual rings of the fragrant fir are more than twenty years.

[0008] A production process of a non-deformed ultra-long extremely energy-efficient ecological board made of solid wood of Chinese fir, which comprises the following steps:

[0009] S1: Pretreatment of the fir wood, removing the edge material of the fir wood, taking the core material after the removal, and sawing the core material into strips with a length of 50 cm and a width of 5 cm;

[0010] S2: outdoor curing, the pre-treated slats are placed outdoors, neatly stacked with spacers, and cured for 25 days;

[0011] S3: high temperature dehydration, vacuum degreasing treatment, after curing, take out the slats, and perform high temperature dehydration and vacuum degreasing treatment on each slat;

[0012] S4: Indoor curing, curing the slats after high temperature dehydration and vacuum degreasing indoors for 7 days, and preparing slab embryos through machines after curing;

[0013] S5: Post-processing: Sanding and veneering the prepared board blank to complete the preparation of the non-deformed ultra-long extreme energy ecological board.

[0014] Preferably, in S1, a sliding table saw is prepared, and the fragrant fir is fixed on the workbench of the sliding table saw to ensure that the fragrant fir does not move during the cutting process. The cutting angle and depth of the sliding table saw are adjusted according to needs, the sliding table saw is started, and the fragrant fir is slowly pushed toward the saw blade to remove the edge material. After the removal is completed, the cut edges are trimmed with a file and sandpaper to make them smooth and flat, so as to obtain the core material of the fragrant fir.

[0015] Preferably, in S2, the outdoor conditions are selected from areas with smooth ventilation, including but not limited to open areas of courtyards and corners with natural ventilation channels; avoid placing them in small closed spaces, close to walls, fences and locations that hinder air circulation, and build a sunshade where the slats are placed to ensure that the shading rate is 50%-70%. The partitions are made of dry wooden strips with a width of 3-5 cm and a thickness of 1-2 cm. A partition is placed every 1-1.5 meters, and the spacing between the slats on the same layer is 10-15 cm. The slats at both ends are staggered by 30-50 cm to avoid problems such as cracking at both ends of the wood due to stress concentration.

[0016] Preferably, in S2, when the slat surface is too dry, use a fine sprayer to spray water appropriately in the early morning or evening, avoid spraying water when the sun is strong, and the amount of water sprayed each time should be enough to slightly moisten the slat surface. When the slat moisture content is too high, if mold occurs, clean the moldy part and improve the ventilation conditions, including but not limited to adding vents, adjusting the stacking method of the slats, and regularly checking whether there are signs of insect bites on the slat surface. If insect pests are found, use environmentally friendly slat preservatives for treatment, including but not limited to borate preservatives, dilute them in proportion, and apply the preservatives to the slat surface with a brush.

[0017] Preferably, in S3, the parameters of high temperature dehydration are: dehydration at 50 degrees for 24 hours; dehydration at 60 degrees for 24 hours; dehydration at 70 degrees for 24 hours; dehydration at 80 degrees for 36 hours; and the slats are cooled to 40 degrees.

[0018] Preferably, in S3, the parameters of vacuum degreasing are: degreasing at 70 degrees for 3 hours; degreasing at 80 degrees for 3 hours; degreasing at 90 degrees for 4 hours; degreasing at 100 degrees for 4 hours; degreasing at 110 degrees for 4 hours, and steam spraying for 20 minutes at the same time; degreasing at 120 degrees for 5 hours after steam spraying, and steam spraying for 30 minutes at the same time; then liposuction is started; degreasing at 130 degrees for 5 hours, and steam spraying is started for 60 minutes, and liposuction is started; degreasing at 140 degrees for 5 hours, and steam spraying is started at the same time. After 120 minutes of steaming, start liposuction; degreasing at 150 degrees for 6 hours, and start steaming 180 minutes later, start liposuction; degreasing at 160 degrees for 4 hours, and start steaming 100 minutes later, start liposuction; degreasing at 170 degrees for 3 hours, and start steaming 80 minutes later, start liposuction and shaping; degreasing at 180 degrees for 2 hours, and start steaming 60 minutes later, start liposuction and shaping; cool down and degreasing for 12 hours, and when the temperature reaches 30 degrees, you can start discharging.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] In the present invention, the problem of the deformation of the fragrant fir can be effectively solved by subjecting the fragrant fir to high-temperature dehydration and vacuum degreasing treatment. The length of the board prepared by this method is 2.75 meters, but the length of the conventional board is 2.44 meters. The cabinet door needs to be divided into 2 sections, which solves the current consumer's requirement for a wardrobe with a door reaching the top. At the same time, the core of the board does not need to be wrapped with eucalyptus veneer on both sides, but is directly veneered on the core of the board, which reduces a layer of glue and has a higher environmental protection level.
