Problems solved by technology

However, ancient wood is a scarce resource, and it is even more difficult to find wood of the same age
In recent years, the old-fashioned new wood process has been widely used in the production of antique furniture. Usually, wood is painted, waxed, acid-etched, etc., and this old-fashioned method is limited to achieve the old-fashioned visual effect.

Embodiment 1

[0046] Embodiment 1: the aging model establishment method of walnut wood, comprises the steps:

[0047] (1) Provide a batch of European walnut wood boards, cut into 90 radial boards of 90*120*10mm. Placed in three environments at 43.47° north latitude (30 blocks for each environment), the conditions are as follows: a. Under laboratory conditions: 20-25°C, 55±5%, do not receive direct sunlight, only receive sunlight Diffuse reflectance, the test time is 60 months, and it is measured every 30 days; b. Place the test piece in a room with a glass window that can be directly exposed to sunlight at an angle of 45° to the vertical direction, the temperature is room temperature 20-25°C, and the relative humidity is 55±5%, the test time is 36 months, and measure once every 15 days; c Simulate sunlight by ultraviolet light, and irradiate 290nm-600nm ultraviolet rays in an environment with a relative humidity of 55% at 40°C, measure once every 3 hours , a total of 216 hours. Each measu...

Abstract

The invention provides a method for quantifying aging degree of furniture materials. The method comprises the following steps: establishing a quantitative relation graph of color change, infrared chromatographic peak area and aging time in the artificial accelerated aging and natural aging process, establishing an aging model of furniture, obtaining an accelerated aging factor, and then predictingthe change trend of future wood aging, and judging the storage time of the aged wood through the relation model.

Description

technical field [0001] The invention relates to the technical field of old furniture restoration and protection, in particular to a method for quantifying the aging degree of wood. Background technique [0002] Old furniture carries a lot of value in art, history, folk customs, culture, etc. It is the crystallization of wisdom and art left by ancestors, and it is a national treasure. In recent years, with the state's emphasis on and support for the protection of cultural relics, the restoration and protection of old furniture has begun to take shape. In the process of restoring old furniture, missing parts and damage to structural parts are often encountered. The restoration principle of "repairing the old with the old" requires that the materials and processes used be as close as possible to the original state of the old furniture. In order to achieve this effect, the same kind of wood from ancient buildings or other furniture fragments is often used to fill in the gaps. ...
