Embodiment 1

[0018] A method for repairing and processing an old wicker chair, comprising the following steps:

[0019] (1) Cleaning and polishing: Use 40-mesh sandpaper to rough the old rattan chair to remove the surface coating and oil layer, then use 80-mesh sandpaper to polish the rattan chair again, so that the xylem is completely leaked out, and then wash it with salt water to polish the rattan chair; It can remove the surface paint and tung oil of the rattan chair, so that the xylem is exposed, which is convenient for the penetration of the active ingredients into the rattan chair during the restoration process;

[0020] (2) Ammonification: Put the polished rattan chair in a vacuum cabinet to evacuate to a vacuum, and then pass ammonia gas with a volume of 13% of the volume of the vacuum cabinet for ammoniation treatment. The temperature is 46°C and the time is 54 minutes. After cleaning, the ammoniated rattan chair is obtained. ; Ammonification can denature and decompose the oil, p...

Embodiment 2

[0030] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:

[0031] For the brine washing described in step (1), the concentration of sodium chloride is 2.7%, the temperature is 98°C, and the time is 29 minutes.

[0032] Step (2) ammonification, the process parameters are: put the polished rattan chair in a vacuum cabinet to evacuate to a vacuum, and pass ammonia gas with a volume of 14% of the volume of the vacuum cabinet for ammoniation treatment at a temperature of 48°C and a time of 56 minutes.

[0033] The parameters of the vacuum impregnation in step (3) are: magnetizer frequency 1.9MHz, temperature 73°C, pressure 0.78MPa, and immersion time 1.8h.

[0034] The impregnation solution described in step (3), wherein the mass ratio of cortisone: deoxycorticosterone is 2:1, and the mass concentration of the mixture of cortisone and deoxycorticosterone in other solvents is 3.7%.

[0035]The parameters of the cooking treatment in step ...

Abstract

The invention discloses a method for repairing and processing an old rattan chair. The method is characterized by comprising the steps of (1) cleaning and polishing the old rattan chair, specifically, polishing the old rattan chair by using 40-mesh abrasive paper and 80-mesh abrasive paper and cleaning the old rattan chair by using a sodium chloride solution; (2) carrying out ammoniation treatment, specifically, putting the polished rattan chair into a vacuum cabinet, introducing ammonia gas and carrying out ammoniation treatment; (3) soaking the rattan chair, specifically, immersing the ammoniated rattan chair into impregnation liquid and carrying out vacuum impregnation by using a magnetizing and pressurizing method; (4) carrying out antibacterial treatment, specifically, immersing the impregnated rattan chair into antibacterial liquid at a constant temperature, alternately using 24kHz ultrasonic waves and 35 kHz ultrasonic waves for impregnation cooking treatment, carrying out cooking repeatedly and carrying out drying for 3-4 times; (5) drying the rattan chair, specifically, placing the antibacterial rattan chair at the temperature of 75-78 DEG C and the temperature of 46-52 DEG C for baking; and (6) carrying out dyeing, specifically, stirring wood wax oil, ethanol and dye at a high speed and then spraying and drying the rattan chair.

Description

technical field [0001] The invention belongs to the technical field of rattan products processing, and in particular relates to a method for repairing and processing old rattan chairs. Background technique [0002] Rattan is the main product of weaving due to its excellent softness and smoothness. The products produced by it are safe, comfortable, natural and fashionable. Moreover, rattan has strong regeneration ability and fast growth speed, which can provide abundant raw materials for processing. , matching with modern environmental protection, low-carbon, natural life style, the rattan handicrafts and furniture products processed by it have gradually become high-end consumer goods. However, rattan products also have their own disadvantages. For example, rattan chairs will have their surface paint faded and inconsistent in color if used for a long time, and there are many dust and impurities on the rattan, which is easy to mold and deteriorate. Scrapping will cause resourc...
