Definitions

  • the invention relates to the woodworking industry, in particular, to the production of sleepers from modified wood.
  • the technical disadvantage of this method is the low 5 form stability of the resulting wood, because when staying in the water, the railroad ties restore their original sizes by 80%.
  • the technical problem, the solution of which the Yu invention is aimed, is to increase the form stability of modified wood for sleepers.
  • a method for producing modified wood including simultaneous drying, impregnation and pressing of wood in an oily antiseptic according to the invention, throughout the process, XJ wood is exposed to a pulsed ultrasonic field with a frequency of 20 kHz, 4 kW, and ultrasound pulses of 2.5- 3 min. alternate with pauses of 6-6.5 minutes.
  • antiseptics such as coal oil, shale oil, liquid toluene condensate (ZhTK), etc. All these antiseptics do not protect the wood from swelling.
  • Ultrasound wood processing under soft conditions leads to an increase permeability (Konovalova NN Establishment of optimal regimes for combined treatment of oak wood with ultrasound and heat to accelerate the maturation of cognac spirits during their tank aging - Abstract. Diss. Cand. Tech. Sciences, M., MGUPP, 2004, 28 s).
  • ultrasonic treatment under severe conditions - a frequency of 20 kHz, a power of 4 kW, leads to the melting of individual wood components - hemicelluloses and part of the lignin in the middle plate, which ultimately can lead to a decrease in the strength of wood.
  • the method is as follows. Raw billets of soft hardwood and conifers are placed in a drying impregnating bath and pump hot antiseptic, such as coal oil. The oil temperature is maintained at 90-100 0 C, the mechanical pressure is 0.8-1.2 MPa for 6 hours. Simultaneously with drying, impregnation and pressing during the whole process, the wood is treated with an ultrasonic field with a frequency of 20 kHz and a power of 4 kW with alternating exposure to an ultrasound pulse of 2.5-3 minutes. and pauses of 6-6.5 minutes. As a result of exposure to ultrasound, pressed wood acquires hydrophobic properties, and its swelling in water does not exceed 12%, as can be seen from the table.
  • a drying impregnating bath and pump hot antiseptic such as coal oil.
  • the oil temperature is maintained at 90-100 0 C
  • the mechanical pressure is 0.8-1.2 MPa for 6 hours.
  • the wood is treated with an ultrasonic field with a frequency of 20 kHz and a power of 4 kW
  • Example 1 Examples of a specific implementation of the invention Example 1.
  • Raw materials - aspen blanks with a diameter of 25 cm, a length of 275 cm were placed in an impregnation bath with coal oil and dried at a temperature of 100 0 C for 6 hours with simultaneous pressing under a pressure of 1.0 MPa.
  • the wood was pulsed by an ultrasonic field with a frequency of 20 kHz and a power of 4 kW with an alternating ultrasound pulse of 3 minutes.
  • the proposed method allows to obtain sleepers from pressed wood of soft hardwood and coniferous species that are superior in strength to oak wood, and the swelling of such sleepers after a long stay in water remains at the level of swelling of natural (unpressed) wood, i.e. fully comply with GOST 78-2004.

Abstract

L'invention concerne l'industrie du bois et notamment la fabrication de traverses à partir de bois modifié. Ce procédé de fabrication de bois modifié comprend le séchage, l'imprégnation et la compression du bois dans un produit antiseptique huileux. Pendant tout le processus, on traite le bois avec un champ ultrasonore pulsé possédant une fréquence de 20 KHz et une puissance de 4 kWt, les impulsions ultrasonores d'une durée de 2,5 à 3 min. sont alternées avec des pauses de 6-6,5 min. L'invention permet d'obtenir une plus grande stabilité de forme du bois modifié destiné à la fabrication de traverses.
