Embodiment 1
[0022] A kind of manufacture craft of mahogany hollow screen, comprises the following steps:
[0023] (1) Material selection: select peach trees with a tree age of more than 20 years and a diameter greater than 15cm as processing materials;
[0024] (2) Sawing wood boards: cut the trunk of the felled peach tree into stakes, and peel off the outer bark; in the wood cutting machine, cut into peach wood boards;
[0025] (3) Boiling in salt water: immerse the peach wood board completely in the heating pool, in which the heating pool has water with a concentration of 0.8% sodium chloride, which has strong penetrating power, can inactivate peach wood cells and microorganisms, and improve the density of peach wood. First soak for 1-2 days; then heat-boil; take out the peach wood board and dry at low temperature until the moisture content is 30%-40%;
[0026] (4) High-pressure fumigation: Put the peach wood boards prepared in step (3) vertically on the distillation layer of the press...
Embodiment 2
[0037] Present embodiment 2 is compared with embodiment 1, and step changes in the following aspects:
[0038] Step (3) boiling in salt water, the concentration of sodium chloride is 0.9%.
[0039] Step (3) boiling in salt water, the water temperature is 98°C, and the treatment time is 5 hours.
[0040] Step (4) high pressure fumigation, its process parameters are:
[0041] The pressure is 2.7Pa, the temperature is raised at a rate of 5°C / 2min, to 116°C, the humidity is 75%, and the time is 4h; the temperature is lowered to 38°C at a rate of 5°C / 5min, and the time is 57min.
[0042] Step (5) acid-base softening, wherein the concentration of sodium hydroxide solution is 0.35%, soaking for 3 hours; the concentration of hydrochloric acid solution is 0.45%, soaking for 3 hours.
[0043] Step (6) drying, its process parameters are:
[0044] In the heating stage, the heating rate is 4°C / 3min, the humidity drop rate is 5% / 2min, the temperature reaches 68°C, the humidity reaches 15...

Abstract
The invention discloses a manufacturing technology of a hollowed-out peach wood screen. The technology is characterized by comprising the steps as follows: (1) material selection is performed as follows: a peach tree with the tree age being 20 years or above is selected as a machining material; (2) board sawing is performed as follows: a peach wood board is 1.8-2 cm thick; (3) heating and boiling in saline water are performed as follows: the board is immersed in water with the sodium chloride concentration ranging from 0.7% to 1% for heating and boiling; (4) high-pressure fumigation is performed as follows: the board is vertically placed on a distillation layer of a pressure cooker, a preservative is added, and high-temperature fumigation is performed; (5) softening in an acid and a base is performed as follows: the board is immersed in a sodium hydroxide solution and a hydrochloric acid solution respectively for soaking treatment; (6) drying is performed as follows: the board is vertically placed in a drying box, and a drying technology is performed; (7) hollowing-out engraving is performed as follows: the hollowed-out screen is engraved; (8) waxing is performed as follows: the screen is coated with wood wax by the aid of a soft brush and is coated repeatedly for 3-4 times. With the technology, the content of moisture in the peach wood board can be reduced, the anti-corrosion and moisture-proof performance can be improved, and the engraving performance and the smoothness of the peach wood board can be improved.
Description
technical field [0001] The invention belongs to the technical field of mahogany handicraft processing, and in particular relates to a manufacturing process of a mahogany hollow screen. Background technique [0002] Peach wood, also known as Jianglong wood and ghost wood, is widely used as material for cutting down evil spirits and making ghosts. The ancients once called peach wood a fairy wood. Legend has it that peach wood was transformed from the stick in the hand of the giant Kuafu chasing the sun. It is used in folk beliefs and important place in culture. Peach wood has a profound meaning and a long history.
