Definitions

  • the present invention relates to a manufacturing method according to claim 1 developed for the production of wooden door panels which have decorative exterior features and enhanced durability, which are used In the production of wooden interior doors that have a large field of work and manufacturing in the woodworking sector.
  • GB 2 364 268 can be shown as an example of the prior art of this technical field as the Invention subjected to this document refers to a door obtained by securing a melamine Impregnated crepe paper or phenolic resin crepe paper coated Medium Density Fiber (MDF) board to a door frame.
  • MDF Medium Density Fiber
  • the wooden door manufacturing method which is developed in order to overcome all of these technical problems and which is used widely in the state of the art, in summary, consists of the steps of compressing and pressing the wood dust and making molded panels by oven baking the dust, and then, cutting these panels in appropriate sizes and obtaining the final product which is the wooden door panel.
  • panel doors have disadvantages arising from some of the technical problems they have.
  • the most important of these disadvantages is that the durability of the doors is reduced depending on the method of production and structural features.
  • Another significant disadvantage is that, it is really hard, and even impossible, to give decorative features to a manufactured panel door with wood carving methods.
  • the woods which will be used as raw materials fort he manufacturing of the wooden door are grouped according to their types (hardwood - softwood).
  • Other cellulosic raw materials can be used instead of using wood as raw material.
  • the woods or other cellulosic raw materials which are grouped according to their types are chipped by being chipped in the chipping machine after being separated from their barks.
  • the chipping is the process where the cutting blades on the revolving drum degrade the wood or the other cellulosic raw materials by cutting them perpendicular to their fibers.
  • the obtained chips are then carried via transporter conveyors to silos or open areas and are stored herein.
  • the chips which are stored in the silo or in the open field according to their types are taken by transporter conveyors in wood mixture rates of 70 ⁇ 10% pine and similar softwood, and 30 ⁇ 10% beech and other hardwood; and are subjected to sifting.
  • the sifting process is conducted in the disc sifter. In the sifting process; the chips are sifted by falling down from the discs on the machine and the spaces between these discs according to the sizes of the pieces. Furthermore, the chips are separated from fine dust, bark and large chips during this sifting process. The large chips are cut in the small chipper so that they have the appropriate size to go back to manufacturing and are, thus, included in the manufacturing process.
  • the sifted chips which have appropriate sizes, are brought to the chips bunker of the fiberizer machine by the transporter conveyors.
  • the chips are transformed into a suberose structure by being pressed with a pressure (suberization piston) applied by the auger conveyor on the opposite side.
  • the suberose chips are carried into the scouring boiler of the fiberizer machine. Chips are boiled while being stirred, under a vapour pressure of 7,5 - 8 bar and a temperature of 160 - 170 °C for a time ranging between 2,5 - 6 minutes.
  • Chemical adhesives, binders, and optionally, other chemical materials which provide resistance against heat, moisture and fire are added into the obtained fibers.
  • the fibers are dried until they reach a moisture gradient of 8 - 10%. After the drying process, the fibers are subjected to a sifting process with an air-operated system; the caked fibers and fine dust metals are separated. Caked and thick fibers are removed from manufacturing and are collected in the waste silo.
  • the dried and sifter fibers are collected in the fiber bunker called Spreading Bunker via the pneumatic conveying system.
  • the fibers which are spread on the conveyor belt in 3.20 - 3.80 kg/m 2 set weights with a 2.5 - 3 m free fall are shaped and balanced (spreading and leveling the fiber).
  • the fibers, which go through the revolving cylinders of the front press and which have their air voids removed, are shaped into outlines of desired moisture, width, length and thickness with the help of the side shaping and crosscut saws.
  • a chemical substance which has adhesive and coater properties is sprayed on the outline in order to make sure that the paper adheres to the outline and to increase the structural strength of the door panel. Then, melaminous decor paper or finish foil paper is spread on the outline which is prepared with the desired width and length.
  • the papers to be spread can have the desired color, pattern and various weights.
  • the outline which is covered with melaminous decor paper or finish foil paper is subjected to layered pressing under a temperature of 150 - 200 °C and a pressure of 150 - 250 Bar, in a patterned swage for 20 - 60 seconds; and thus, a door panel which is 950 - 1100 kg/m 3 dense, 3.2 ⁇ 0.2 mm thick, which is resistant to heat, moisture, cracking, breaking and scratching, which is easy to clean, ergonomic and which is covered with a patterned paper on the surface is obtained.
  • the paper-covered panels which are out of the hot layered pres are left to cool for 1- 24 hours in order to prevent twisting and buckling. After the cooling process, the panels are sized by cutting them in desired width and length via circular saws. The panels which have undergone the sizing process are divided into quality classes and the paper-covered panels which have the same model and size are packaged as products that are available to the door manufacturers.
