Title:
MICROWAVE-IMPREGNATING MODIFIED TREATMENT PROCESS FOR WOOD FOR GROUND HEATING SOLID-WOOD FLOORING
Document Type and Number:
WIPO Patent Application WO/2019/006836
Kind Code:
A1
Abstract:
Disclosed is a microwave-impregnating modified treatment process for wood for ground heating solid-wood flooring. The process comprises a. microwave treatment: putting wood in a microwave treatment device to undergo microwave treatment, wherein a microwave treatment process is carried out three times, and a treatment time interval is 1-3 min; regulating the radiation power to 2-5 KW the first time, the radiation time being 30-60 s; regulating the radiation power to 1-4 KW the second time, the radiation time being 20-40 s; and regulating the radiation power to 0.2-0.8 KW the third time, the radiation time being 8-15 s; b. cooling: carrying out cooling to reduce the temperature, and removing the wood from a tank when the temperature is reduced to 25-40°C; c. primary impregnation: impregnating the wood in an analytically pure water solution in a mass fraction of 20-30 % at an impregnation temperature of 50-70°C, taking out the wood and drying same after impregnating the wood for 25-35 h, wherein drying the wood is carried out until the water content reaches 8 %; d. secondary impregnation: putting the dried wood in a vacuum impregnating tank, regulating a vacuum degree to -0.20-(-0.10) MPa, maintaining the vacuum degree for 10-20 min, using a negative pressure to inject resin into a tank body at the same time, so that the wood is impregnated in the resin, and controlling the pressure to be 1-3 MPa and maintaining the pressure for 1-4 h; and e. obtaining the finished product: drying the wood and obtaining a final material.
