Definitions

  • the present invention relates to a composite wood processing method and equipment for unidirectionally pressurizing and filling wood, by which natural wood 30, including bamboo, which is suitable for acting as a building material, is made into the composite wood having fire-proof and preservation functions and is thus particularly suitable for an application in markets of the building materials.
  • wood is put into a pressure tank which can sustain with high pressure and then a solution is added into the pressure tank, followed by carrying out a pressurization process, thereby speeding up osmosis of the solution into the wood.
  • this method requires exerting very large pressure to the pressure tank (a pressure value of about 10 ⁇ 30kg/cm 2 ); therefore, an equipment cost of the pressure tank is high and it is also very dangerous to work under this kind of condition. As a result, a production cost is very high and the processed wood will be rather expensive, which is often complained by users..
  • vascular tissues and conductive tissues which are assembled by tracheary elements arranged longitudinally to transport water and nutrients, and the vascular tissues and the conductive tissues in the trunk will not be damaged after making the wood.
  • the property of longitudinal arrangement intensifies transversal resistance to pressure.
  • the composite wood processing equipment for unidirectionally pressurizing and filling wood includes a pressure vessel and a solution pressurization device.
  • An interior of the pressure vessel allows at least one piece of wood to be put into, a side of the pressure vessel is provided with openings, an amount of which being equal to that of the wood and the other side of the pressure vessel is connected to the solution pressurization device to fill the solution into the pressure vessel.
  • Each opening of the said pressure vessel is provided with a plug, an outline of the plug fits with shape of the opening of the pressure vessel to close the opening, and an inner rim of the plug is provided with a through-hole to seal with an outer rim of the wood, such that a front end part of the wood can be connected with atmosphere through the through-hole of the plug.
  • the solution pressurization device pressurizes and fills the solution into the pressure vessel, as the front end parts of the wood are connected with the atmosphere through the through-holes of the plugs, negative pressure will be formed at the front end parts of the wood by the pressurized solution in the pressure vessel, allowing the solution to exert pressure from rear end parts to the front end parts of the wood.
  • the solution can be quickly permeated into the wood from the rear end parts toward the front end parts of the wood.
  • the aforementioned solution is a gaseous or liquid solution added by a fine grain material (a grain size of smaller than 0.002mm).
  • the additive includes clay such as kaolinite, illite or montmorillonite, a nano material and a natural or chemical fire-proof agent or preservative agent, which allows the wood to have the fire-proof and preservation functions when the composite wood is formed after the solution has permeated and been adsorbed in wood tissues.
  • the method of the present invention puts the wood longitudinally into the pressure vessel, seals the wood with the pressure vessel and pressurizes and fills the solution into the pressure vessel after the front end parts of the wood have been connected with the atmosphere, allowing the solution to enter into the wood through the ducts of wood that transport water and nutrients from the rear end parts of the wood.
  • the composite wood processing method utilizes the original ducts of wood that transport water and nutrients, the composite wood can be formed by lower pressure and with a saving of energy.
  • the processed composite wood can be provided with the fire-proof and preservation functions, the wood intensity can be improved and the lifetime of usage can be extended, thereby achieving the object of wide application in the markets of building materials and having the multiple advantages of fast processing, stability, labor saving and time saving.
  • FIG. 1 shows a structural schematic view of composite wood processing equipment of the present invention.
  • composite wood processing equipment for unidirectionally pressurizing and filling wood comprises a pressure vessel 10 and a solution pressurization device 20.
  • An interior of the pressure vessel 10 provides for at least one piece of wood 30 (natural wood including bamboo) to be put into longitudinally; a side of the pressure vessel 10 is provided with openings 11, an amount of which being equal to that of the wood 30; and the other side of the pressure vessel 10 is connected to the solution pressurization device 20 which fills the solution into the pressure vessel 10.
  • Each opening 11 of the said pressure vessel 10 is provided with a plug 40, an outline of the plug 40 fits with shape of the opening 11 of the pressure vessel 10 to close the opening 11, an inner rim of the plug 40 is provided with a through-hole 41 and an inner rim of the through-hole 41 can be sealed with an outer rim of the wood 30, allowing a front end part 31 of the wood 30 to be connected with atmosphere through the through-hole 41 of the plug 40.
  • the plug 40 can be made by rubber or soft plastic, whereas the method for sealing the inner rim of the through-hole 41 with the outer rim of the wood 30 can be achieved by sealing seams with water-proof glue or a washer, fitting with shape of the wood 30.
  • the solution pressurization device 20 pressurizes and fills the solution into the pressure vessel 10
  • the front end parts 31 of the wood 30 are connected with the atmosphere through the through-holes 41 of the plugs 40
  • negative pressure will be formed at the front end parts 31 of the wood 30 by the solution that is pressurized in the pressure vessel 10, allowing the solution in the pressure vessel 10 to exert pressure from rear end parts 32 of the wood 30 to the front end parts 31.
  • the solution can be quickly permeated into the wood 30 through original ducts which transport water and nutrients from the rear end parts 32 of the wood 30 toward the front end parts 31 of the wood 30.
  • the aforementioned solution is a solution added by a natural or chemical fire-proof agent or preservative agent, including clay such as kaolinite, illite or montmorillonite, or a nano-material.
  • the solution is a gaseous or liquid solution added by a fine grain material.
  • the composite wood which is formed after the solution has permeated and been absorbed into tissues of the wood 30 can be provided with fire-proof and preservation functions.
  • the front end parts 31 of the wood 30 are exposed out of the through-holes 41 of the plugs 40.
  • the front end part 31 of the wood 30 is aligned with a front end of the through-hole 41 of the plug 40; whereas, in FIG. 4 , the front end part 31 of the wood 30 is indented in the front end of the through-hole 41 of the plug 40. Both are feasible embodiments.
  • the composite wood processing method for unidirectionally pressurizing and filling wood comprises following steps:
  • the composite wood processing method utilizes the original ducts of wood that transport water and nutrients to permeate the solution into the wood, the composite wood can be formed by lower pressure and with a saving of energy. Accordingly, an equipment cost is cheaper, the processed composite wood can be provided with the fire-proof and preservation functions, wood intensity can be improved and a lifetime of usage can be extended, thereby achieving an object of wide application in the markets of building materials, which is provided with multiple advantages of fast processing, stability, labor saving and time saving, in comparison with the prior art.
