METHOD OF MAKING PRODUCTS FROM WOOD

Methods are known for the manufacture of wood from wood and for the pressing of the workpiece, and in advance of it, in the heated state and at the same time, the effects of ultrasound and pressure by resin. However, these siobi not obesiechivayut uniform and complete ironics.

The proposed method consists in ironing the heated billet from one of the ends, supplying the resin with iodine, ultrasound and pressure, while evacuating with its opposite end. Then, the billet is dried until the solvent is volatilized with emols and compressed with 100-110 ° C, followed by heating to 150-17Q ° C.

FIG. 1 and 2 two variants of the device are shown for carrying out the described method.

Wood in the form of a continuous wave of any humidity is a hall, it is between two flanges 1 and 2 with an internal cone. Vacuum is applied to the flag 2 and a tap is installed to lower the water; To the flange / from the side of attachment, a magnetic magnetic converter 3 of the ultrasonic generator and pressurized systems of hot compressed air and resin are fed to the system.

fines, i.e., Orilitsa 1, are supplied with hot compressed air (at least 5 atm), which is forced under pressure through the wood, drying it. Moisture is blown out 1gg through the drain specks. In addition, compressed hot air breaks the hyperfacial vascular neregorodn, which contributes to a better dispersion of the filler into the wood.

In the process of ianolieni, the resin is fed under pressure (at least 3 atm) to the resin, while switching on the ultrasonic generator. Under the action of ultrasonic vibrations and pressure, the resin penetrates the wood, floor of pores and vessels. For more than 1P1 dispersed nplioiii wood at the other end of the harvesting created vacuum.

For nanolenny small blanks, I have Hj, Hx complex configuration, the device can be varied. The refinishing is made by polpi polo: 1 immersing the billet in a papolitel. 2). Wood blanks help the vessel 4 with the nap1N1tel. The following is attached to the bottom of the vessel: an agitio-strictium transducer of the ultrasonic generator. By creating a vacuum vessel (up to 99%), air is pumped out of the wood and removed from the vessel. Prnz11ako; At an eye for air pumping, Irekran1 is used, the evacuation of air bubbles is PZ: apolp1 tel. After the air has been pumped out, the ultrasonic generator is turned on and an overpressure is created in the tank. Due to the ultrasonic oscillation and overpressure, the nstoissio resin penetrates the wood, filling its pores and vessels. Wood blanks in a vessel are positioned in such a way that the ultrasonic vibrations tutorial would be parallel to the fiber drabs, i.e. would be perceived as the end part of the wood.

After the wood is dried, the solvent of the resin is completely volatilized and pressed at a temperature of 100-110 ° C, followed by heating to 150-170 ° C, during which the resin is polymerised, the cementite is woody fibers of wood.
