Definitions

  • the invention relates to a composite solid wood board and a crucible preparation process and a product thereof, in particular to a composite solid wood board and a crucible preparation process and a product using the artificial timber forest wood as raw materials.
  • the artificial timber forest Due to the short material production period and fast growth rate, the artificial timber forest is mostly loose in wood, low in density, hardness and strength, and has poor processing properties.
  • the use of artificial timber forests has always required natural forests (high-quality materials) to be used as fabrics and cannot be used independently. Therefore, the value of artificial fast-growing and high-yield forestry timber is very low, and the goal of artificial wood forest replacing natural forest is difficult to achieve. Summary of the invention
  • the technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a new preparation process by which high-quality composite solid wood boards with excellent appearance and good physical and mechanical properties can be prepared by using artificial timber forest wood as raw materials.
  • Composite solid wood enamel
  • a composite solid wood board and crucible preparation process the steps are as follows:
  • step 2) Modify the material obtained in step 2), slice the wood chips, dry the wood chips, trim the wood chips, classify the wood chips, glue the composite, and saw the finished product.
  • the artificial timber forest wood is preferably used as the log; in the step 2), when the wood chips are sliced, the longitudinal planing is preferably adopted, so that the thickness specifications and the fancy varieties of the wood chips are more, so that various kinds of wood chips can be produced. Thick wood and composite solid wood slabs of various specifications; in step 2), in the case of adhesive compounding, according to the different needs of composite solid wood panels, enamel appearance and physical and mechanical properties, the slab of two layers of wood The grain direction faces may be in the same direction, or may be perpendicular or at other angles, that is, the same direction or the vertical and horizontal fit.
  • the invention combines the needs of the Chinese market, integrates a set of processes, and firstly transforms the artificial timber forest with low density, low strength and poor hardness into a post-treatment material with high density, hardness, high strength and good processing performance.
  • the treated material is cut longitudinally or obliquely to obtain a wood chip (single board) with smooth surface, and then classified and glued to make the low-cost artificial timber material into a beautiful appearance with good physical and mechanical properties.
  • Composite solid wood panels and composite solid wood enamel are used to make the low-cost artificial timber material into a beautiful appearance with good physical and mechanical properties.
  • Figure 2 Cylindrical wood with the same diameter after rounding.
  • Fig. 3 The cylindrical wood is sawn with a band saw in a longitudinal direction parallel to the center line of the cylinder to obtain a small side skin, and a longitudinal plane is used as the cutting base surface.
  • Figure 4 Schematic diagram of longitudinal planing.
  • Raw wood rounding After cutting the artificial timber forest wood and cutting it into a certain length of logs as needed, cut it into a cylinder of uniform diameter on the rotary cutting machine (refer to Figure 2).
  • cylindrical sawing edge the cylinder with a band saw in the longitudinal direction parallel to the center line of the cylinder saw a small side skin, a vertical plane as a planing base (refer to Figure 3),
  • Modification treatment The column after sawing is post-treated by conventional modification method.
  • Sliced wood chips The modified wood is longitudinally cut on a wood planer (the direction of the cutter is parallel to the center line of the cylinder, see Figure 4), and the sliced wood chips (single boards) of the same thickness are obtained. The thickness of the wood chips depends on actual needs. 5. Drying of wood chips: Slice the wood chips on a dryer or naturally dry to a suitable moisture content.
  • Wood chips The two long sides of the wood chips are trimmed and straightened, so that the wood chips and the wood chips are seamlessly combined.
  • Classification of wood chips The dried wood chips are divided into two types, one is non-defective (the texture is clear and beautiful, the color is basically the same, there is no local decay, no dead knot, no insects or holes and other defects caused by processing), as Composite solid wood board, enamel surface layer; another type of defective is used for composite solid wood board, enamel inner layer.
  • Adhesive compounding a. Firstly, the pieces of wood chips are bonded and assembled to the required width, and placed on the flat press machine table; or the single piece of wood chips can be directly aligned on the flat press machine to form the required width. Machine or manual chipping. The close sides of the two pieces of wood should be tight and seamless. b. Next, apply a suitable wood adhesive to the surface of the spliced wood chips. The adhesive can be applied mechanically or manually, requiring uniform application and moderate thickness. c. Cover the glued wood chips with another layer of stitched wood chips, or directly cover the individual pieces of wood one by one.
  • the direction of the grain of the two layers of wood chips may be the same direction, or may be perpendicular or at other angles (ie, the same direction or vertical and horizontal stickers) Combined).
  • d. Repeat b, c, until the required thickness. Generally, the composite solid wood board is thinner, and the composite solid wood board is thicker.
  • Open the flat press to press the adhesive to cure, and the wood chip is glued and shaped into a composite solid wood board and a slab blank. The pressure and time parameters for cold or hot pressing and pressing are selected depending on the equipment conditions and the curing conditions of the adhesive.
  • Composite solid wood Use a single-piece saw, multi-blade saw or other equipment to cut a composite solid wood billet into a coffin of the specified width (see Figure 5).
  • Composite solid wood panels Trimming composite solid wood panels into sheets of the required size using a single-piece saw or other equipment (refer to Figure 6).
