Abstract

The invention discloses a microwave-dipping modifying treatment process for wood of a solid wood ground heating floor. The treatment process comprises a, microwave treatment: placing the wood in a microwave treatment device for performing microwave treatment, wherein the microwave treatment process is divided into 3 times, and the treatment every time has a time interval of 1-3min; adjusting radiation power to 2-5KW for the first time, wherein the radiation time is 30-60s; adjusting the radiation power to 1-4KW for the second time, wherein the radiation time is 20-40s; adjusting the radiation power to 0.2-0.8KW for the third time, wherein the radiation time is 8-15s; b, cooling; performing cooling and temperature reduction, taking the wood out of a tank after the temperature is reduced to 25-40 DEG C; c dipping for the first time: dipping the wood in an analysis pure water solution with a mass percent of 20-30%, wherein a dipping temperature is 50-70 DEG C; taking out for drying after dipping for 25-35h, and drying till a water content is 8%; d, dipping for the second time: placing the well-dried wood in a vacuum dipping tank, adjusting a vacuum degree to -0.20 to (-0.10)MPa, keeping for 10-20min, using negative pressure to inject resin into the tank body so as to dip the wood in the resin, and controlling a pressure to be 1-3MPa and keeping for 1-4h; and e: obtaining a finished product: drying to obtain the final material.

Description

technical field [0001] The invention relates to a wood modification treatment for solid wood floors for floor heating, in particular to a wood microwave-impregnation modification treatment process for solid wood floor heating, and relates to the field of wood floor and furniture manufacturing. Background technique [0002] In recent years, with the improvement of people's consumption level, people pay more and more attention to high-quality home life experience, especially people's requirements for environmental protection and living environment comfort, the solid wood floor heating industry is also showing a warming trend. Timber is also in increasing demand. Due to the problems of conventional wood drying and modification for a long time, high energy consumption and serious pollution, in addition, some common solid wood materials cannot be used in floor heating environments due to their natural properties of shrinking when dry and expanding when wet, and their dimensions a...
