As shown in fig. 1, there is shown a flow chart of the teak sun-curing process of the present invention. The teak drying plate treatment process comprises the following steps: s1, placing the first surface of the teak board upwards on a plate drying rack; s2, flushing the first surface of the teak board placed on the drying rack; s3, turning the teak board flushed with water to ensure that no accumulated water remains on the first surface of the teak board; s4, continuously placing the teak board without accumulated water residue on the first surface upwards on a board drying rack for drying, and when the temperature of the first surface of the teak board reaches 40-42 ℃, preferably 42 ℃, performing water flushing treatment on the first surface of the teak board placed on the board drying rack again; repeating the step S3 once, continuously placing the teak board without accumulated water residue on the first surface upwards on the plate drying frame for drying, and placing the second surface of the teak board upwards on the plate drying frame when the first surface temperature of the teak board reaches 40-42 ℃ again, preferably 42 ℃; s5, flushing the second surface of the teak board placed on the drying rack; s6, turning the teak board flushed with water to ensure that no water is left on the second surface; s7, placing the teak board without accumulated water residue on the second surface on a drying rack to be dried in the sun, and when the temperature of the second surface of the teak board reaches 40-42 ℃, preferably 42 ℃, performing water flushing treatment on the second surface of the teak board placed on the drying rack again; repeating the step S6 once, continuously placing the teak board with no accumulated water residue on the second surface upwards on the plate drying frame for drying, and placing the first surface of the teak board upwards on the plate drying frame when the temperature of the second surface of the teak board reaches 40-42 ℃ again, preferably 42 ℃; s8, repeating the steps S2-S7 until the first surface and the second surface of the teak board are golden yellow and uniform in color.
According to the teak board drying treatment process, the first surface and the second surface of the teak board are subjected to water flushing treatment for multiple times, so that dust on the surfaces of the teak board can be removed, water flushing is performed when the temperature of the first surface and the temperature of the second surface of the teak board reach 40-42 ℃, and the step is repeated for multiple times, so that impurities such as silt in a conduit and a sieve tube of the teak board can be extruded out and washed away from the surfaces by water according to the principle of thermal expansion and cold contraction, the surface layer of the whole teak board has higher cleanliness, and the risk of cracking the board surface is reduced; in addition, in the teak board drying treatment process, the first surface and the second surface of the teak board are alternately washed with water, so that the damage of the teak board due to overlarge internal stress in the process of drying the teak board can be avoided, and the reliability of drying the teak board is ensured.
Preferably, step S1 is preceded by step S01: the first and second surfaces of the teak board were polished with sand paper. The first surface and the second surface through polishing the teak board can make the surface of the teak board become more level and smooth to make things convenient for subsequent processing step more. For example, the flow of water is facilitated, and water accumulation is avoided; the final teak finished product can also have better aesthetic property. Specifically, the first surface and the second surface may be sanded with 180-mesh sandpaper. Of course, a lower or higher grit sandpaper may be used depending on the application.
Preferably, the water pressure of the flush water in step S2 is 3.5 MPa. The water pressure of flushing water in step S5 was 3.5 MPa. The impurities such as silt in the guide pipe and the sieve pipe can be further removed through the water pressure of specific pressure, and the impurities such as silt can be prevented from remaining on the surface of the teak board.
Preferably, the angle between the teak board placed on the rack and the horizontal plane in step S1 is 15 °. In the step S4, the included angle between the teak board and the horizontal plane is 15 degrees after the teak board is placed on the plate drying frame. Through setting teak board to specific angle and advancing, can be convenient for the flow down of water after washing by water, be unlikely to again simultaneously to let the water flow down at the excessive speed for there is impurity such as silt in pipe and the screen pipe can be taken away to teak board's surface has sufficient water capacity. In addition, the water flushing mode is adopted in the invention, so that the water content of the teak board is not too high.
Preferably, step S8 is followed by step S81: the teak board is put into the room for storage. The temperature of the first surface or the second surface when the teak board is stored in the room is 42 ℃. The teak board is collected into the room for storage, so that the teak board can be better protected, and the teak board is collected at the temperature of 42 degrees, so that the surface of the teak board can be kept dry, and the damage to the teak board in the storage process is avoided.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
