A treatment method for improving the dimensional stability of mahogany

Abstract

The invention relates to a processing method for increasing the dimensional stability of rosewood, which belongs to the technical field of wood processing methods. The processing method comprises the following steps of sending dried rosewood to a closed greenhouse; performing cold treatment, wherein refrigeration equipment is started to operate, the temperature in the greenhouse is slowly reduced to a lower limiting value of the preset temperature, and the temperature in the greenhouse is kept; shutting down the refrigeration equipment after continuous cold treatment for specific time; performing heat treatment, wherein heating equipment is started to operate, the temperature in the greenhouse is slowly increased to an upper limiting value of the preset temperature, and then the temperature is kept; operating an indoor dehumidifier at the same time so as to absorb water vapor generated by temperature rise, and keeping the greenhouse dry; shutting down the heating equipment after continuous heat treatment for specific time; and repeatedly performing cold and heat treatment for 3 to 6 times in sequence. According to the processing method for increasing the dimensional stability of the rosewood, the cold and heat treatment is repeatedly performed, so that expansion and contraction coefficients of the rosewood are effectively reduced, and the dimensional stability of the rosewood is increased.

Description

technical field [0001] The invention belongs to the technical field of wood treatment methods, in particular to a treatment method for improving the dimensional stability of mahogany. Background technique [0002] The dimensional stability of mahogany is of great significance for improving the quality of mahogany furniture. As mahogany furniture is favored by consumers, mahogany furniture has appeared in many families from the south to Singapore and the north to Heilongjiang. The north-south latitude span of the target sales area is huge, so the impact of climate on mahogany furniture cannot be ignored. In order to ensure that mahogany furniture does not deform or crack, manufacturers and consumers put forward higher requirements for the dimensional stability of mahogany, so that the expansion of mahogany in hot weather and the shrinkage of mahogany in cold weather can reach the acceptable range of mahogany materials . [0003] The existing typical method is that the Chin...

Problems solved by technology

However, for mahogany, this method does not substantially improve the dimensional stability of the wood. Once the surface filling material falls off or loosens, it still faces the risk of expansion and deformation.

In addition, the components of mahogany furniture are not only flat plates, but also a large number of round bars and square sticks of different sizes. It is difficult to realize surface filling, and the scope of application of the inventive method is limited.
