Embodiment 1

[0030] A drying process for mahogany, comprising the steps of:

[0031] a. Anti-oxidation treatment, mix 0.25%-0.30% propyl gallate aqueous solution with 60%-70% tea polyphenol aqueous solution, the mixing temperature is 40-50 degrees, soak the redwood in the mixed liquid , the time is 2-3 hours;

[0032] After a large number of experiments, it was found that a certain concentration of propyl gallate and tea polyphenols can prevent the redwood from discoloration during the drying process. The substance cannot be oxidized in the subsequent drying step, which greatly reduces the discoloration of the mahogany, so that the color of the mahogany is good, and the appearance of the processed furniture is beautiful.

[0033] b, preheating, so that the humid air with a temperature of 70-75 degrees and a humidity of 0.08kg / m3-0.13 kg / m3 circulates through the above-mentioned redwood for 70-80min;

[0034] When moist air passes through the mahogany, part of the water vapor in the air w...

Embodiment 2

[0056] In the present embodiment, take the rosewood kind in the mahogany as an example:

[0057] a. Mix the 0.3% propyl gallate aqueous solution with the 60% tea polyphenol aqueous solution, the mixing temperature is 40 degrees, soak the redwood in the mixed liquid for 2.5 hours;

[0058] b. Make the humid air with a temperature of 70 degrees and a humidity of 0.08kg / m3 circulate through the above-mentioned mahogany for 80 minutes;

[0059] c, make the temperature be 30 degrees and the humid air with humidity 0.05kg / m3 circulate and flow through the above-mentioned mahogany for 60min;

[0060] d. Make the humid air with a temperature of 20 degrees and a humidity of 0.03kg / m3 circulate through the above-mentioned mahogany for 40 minutes;

[0061] e. Make the humid air with a temperature of 45 degrees and a humidity of 0.01kg / m3 circulate through the above-mentioned mahogany for 60 minutes;

[0062] f, making the temperature 55 degrees and humidity 0.004kg / m3 humid air circula...

Abstract

The invention provides a drying process of rosewood, and belonging to the field of furniture making. The drying process comprises the following steps: anti-oxidization treatment, preheating, first-stage temperature and humidity reduction, second-stage temperature and humidity reduction, first-stage temperature increase and humidity reduction, second-stage temperature increase and humidity reduction, and surface protection. The rosewood is subjected to anti-oxidization treatment before being preheated, so that the discoloring phenomenon of the rosewood is greatly reduced to ensure that the color of the rosewood is good, and processed furniture is attractive in appearance and color and excellent in anti-oxidization capability. The drying process has the advantage that the rosewood can be protected from being discolored.

Description

technical field [0001] The invention belongs to the field of furniture manufacturing and relates to a drying process for mahogany. Background technique [0002] Mahogany, the collective name for high-end and precious furniture materials in China, originally refers to red hardwood, with many varieties; after the 1980s, the demand for mahogany furniture increased, and the industry urgently needed to be regulated. According to the standard, the standard of mahogany is: two families, five genera, eight types, and thirty three types. Because of its slow growth, hard material, and more than a few hundred years of growth period, many mahogany native to southern my country were felled as early as the Ming and Qing Dynasties. Today's mahogany is mostly produced in Southeast Asia, Africa, my country's Guangdong and Yunnan have cultivated and introduced cultivation. The difference between the heartwood and sapwood of the wood is obvious, the sapwood is narrow, off-white; the heartwo...
