Embodiment 1

[0018] (1) Pretreatment: The wood to be treated is red sandalwood hedgehog, which has a pungent sour and spicy smell, and the density of red sandalwood hedgehog is 0.76g / cm 3 , with an initial moisture content of 38%, and a thickness of 12mm to be dried for the red sandalwood hedgehog to be treated so that its moisture content is 25%;

[0019] (2) Saturated steam treatment: place the pretreated red sandalwood hedgehog in a saturated steam medium, control the temperature of saturated steam to 160°C, the pressure to 0.63MPa, and the treatment time to 3 hours;

[0020] (3) Cyclic treatment: After the saturated steam treatment, release the pressure. When the air pressure reaches 0.1Mpa, keep it for 30 minutes; then heat and pressurize until the temperature is 160°C, the pressure is 0.63MPa, and the treatment time for heat preservation and pressure is 3 hours. , the number of cycles is 4 times.

[0021] (4) Tempering treatment: After the cycle treatment, the hedgehog red sandalwoo...

Abstract

Provided is a method for removing the smell of rosewood. According to the method, saturated steam under certain pressure intensity serves as a heat-transfer medium, the pungent smell in the rosewood is removed through steam adsorption, and the technical purpose of removing the pungent smell in the rosewood is achieved. Through the method, the process is simple, the cost is reduced, and the purpose of drying the rosewood can be achieved while the smell is removed. The certain pungent smell in the rosewood can be removed; moreover, the cracking ratio of the rosewood can be reduced significantly, and the dimensional stability of the rosewood is improved.

Description

technical field [0001] The invention belongs to the technical field of wood heat treatment, and in particular relates to a method for removing the smell of mahogany. Background technique [0002] Wood is the main material used in furniture and interior decoration. However, some woods cause people to be unhappy because they release pungent odors during use. The wood itself is odorless, and the reason why there are various odors is due to the volatile oil, tannin, resin, gum, etc. contained in the wood cell cavity and the deposits on the cell wall. The vast majority of wood contains extractives, resulting in a variety of odors. For example, the hedgehog red sandalwood has a spicy and sour smell, and the white flower cliff pea has a sour and traditional Chinese medicine smell. Such smells will not only affect people's sense of smell, but also make the wood lack a sense of grade to a certain extent. In order to improve the satisfaction of wood in the customer group and make p...
