Embodiment 1
[0057] This embodiment discloses a kind of production method of solid wood thick core board, comprises the following steps:
[0058] S1. The preparation of thick core board specifically includes:
[0059] (1) Selection of raw materials: choose pine logs with a diameter of 50 cm or more imported from New Zealand as raw materials for thick core board processing, and choose Australian red eucalyptus single-piece veneer as raw materials for panel processing;
[0060] (2) Degreasing of pine wood: peel off the selected pine wood with a diameter of 2 cm, remove the natural weathering layer, then immerse the stripped pine wood in warm water at 50°, and after natural immersion for 12 hours, the water temperature will rise to 80°- 100°, keep it for 20-26 hours, let the pine fiber expand with high strength, remove the pine grease and cool down, take out the log after the water temperature drops to 35°, and proceed to the next step of processing, while maintaining the air humidity in the ...
Embodiment 2
[0082] like Figure 4 As shown, this embodiment discloses a solid wood thick core floor, including a panel 104, a first core layer 102, a thick core layer 101, a second core layer 103 and a back board 105, and the thickness of the first core board layer is the same as that of the second core board layer, and the wood fiber directions of the first core board layer and the second core board layer are perpendicular to the wood fiber direction of the thick core board layer, and the second core board layer The first core board layer, the thick core board layer and the third core board layer are all wood core boards, the first core board layer and the second core board layer are all eucalyptus, the thick core board is pine wood, and the The first core layer, the thick core layer and the third core layer are all directly cut into a whole core from logs.
[0083] Among the above, the patterned paper layer is pasted on the top of the panel layer, and the moisture-proof paper layer is ...
Embodiment 3
[0106] Among them, the soaking, cooking and degreasing of logs are carried out in cooking equipment, such as figure 1 As shown, a kind of cooking equipment for rotary cutting thick core board provided by the present embodiment comprises:
[0107] container 10 for liquid and log segments;
[0108] A heating device 20 arranged in the container 10;
[0109] and a hoisting device 40 for hoisting log segments into and out of the container 10;
[0110] An opening for hoisting in and out log segments is arranged above the container 10; a cover 30 for sealing the opening is arranged on the opening.
[0111] When in use, put the log section for rotary cutting into the container 10, start the heating device 20 to heat the liquid, after the log section is heated, the log section is softened and the flexibility increases, so that the thickness of the log section can reach 7mm ~12mm entire rotary cut veneer (i.e. thick core board), the thickness is greatly increased, and the whole rotar...
