Problems solved by technology

[0002] Pine wood has the characteristics of pine fragrance, light yellow color, many boils, quick response to atmospheric temperature, easy to swell, and extremely difficult to dry naturally. Cracking; however, most of the current methods to prevent pine deformation and cracking use toxic chemical reagents, and the process is complicated. While delaying the deformation and cracking of pine furniture, it will also endanger human health during the preparation and use of furniture. Therefore, a safe Healthy, simple and efficient method to prevent deformation and cracking of pine wood

Embodiment 1

[0020] A method for preventing deformation and cracking of pine, comprising the following steps:

[0021] (1) Arrangement: cut off the felled pine wood according to the required length, retain the pine bark, increase the protective effect of the pine bark, inhibit the color change in the process of pine wood treatment, and facilitate the unified bleaching treatment in the later stage to obtain pine wood sections;

[0022] (2) Freezing: Put the pine wood section in the treatment room, adjust the temperature to 11°C and let it stand for 6 hours, then lower the temperature to 2°C and let it stand for 15 hours, then lower the temperature to -7°C, let it stand for 26 hours, continue Lower the temperature to -32°C, keep it warm for 50 hours, reduce the moisture in the pine wood in a low temperature environment, increase the gaps between the pine fibers, improve the tolerance of the pine wood to temperature and humidity, and reduce the impact of environmental changes on the pine wood....

Embodiment 2

[0034] A method for preventing deformation and cracking of pine, comprising the following steps:

[0035] (1) Arrangement: cut off the felled pine wood according to the required length, retain the pine bark, increase the protective effect of the pine bark, inhibit the color change in the process of pine wood treatment, and facilitate the unified bleaching treatment in the later stage to obtain pine wood sections;

[0036] (2) Freezing: Put the pine wood section in the treatment room, adjust the temperature to 12°C and let it stand for 7 hours, then lower the temperature to 3°C and let it stand for 16 hours, then lower the temperature to -6°C, let it stand for 27 hours, continue Lower the temperature to -31°C, keep it warm for 55 hours, reduce the moisture in the pine wood in a low temperature environment, increase the gaps between the pine fibers, improve the tolerance of the pine wood to temperature and humidity, and reduce the impact of environmental changes on the pine wood....

Embodiment 3

[0048] A method for preventing deformation and cracking of pine, comprising the following steps:

[0049] (1) Arrangement: cut off the felled pine wood according to the required length, retain the pine bark, increase the protective effect of the pine bark, inhibit the color change in the process of pine wood treatment, and facilitate the unified bleaching treatment in the later stage to obtain pine wood sections;

[0050] (2) Freezing: Put the pine wood section in the treatment room, adjust the temperature to 13°C and let it stand for 8 hours, then lower the temperature to 4°C and let it stand for 17 hours, then lower the temperature to -5°C, let it stand for 28 hours, continue Lower the temperature to -30°C, keep it warm for 60 hours, reduce the moisture in the pine wood in a low temperature environment, increase the gaps between the pine fibers, improve the tolerance of the pine wood to temperature and humidity, and reduce the impact of environmental changes on the pine wood....

Abstract

The invention mainly relates to the technical field of wood product processing, and discloses a method for preventing deformation and cracking of pines. The method comprises arrangement, refrigeration, fermentation, primary drying, humidification and secondary drying; the method is simple and convenient in batch processing; no poisonous reagent is added in the treatment process to achieve safety and health; the water content of the treated pines is stable, and the water absorbing capacity is reduced, so that deformation and cracking are radically prevented, the service life is prolonged by 14.5%, and the use value of pine products is obviously improved; the cut pines are cut according to needed lengths; pine barks are retained; the protecting effect of the pine barks is improved, so that the color change in the pine treatment process is inhibited, and later unified bleaching treatment is convenient; and pine sections are put in a treatment chamber to gradually cool for refrigeration, so that the water in the pines is reduced under low-temperature environment, gaps among pine fibers are increased, the resistance of the pines to temperature and humidity is improved, the influence of environmental change to the pines is relieved, and deformation and cracking of the pines are prevented.

Description

technical field [0001] The invention mainly relates to the technical field of wood product processing, in particular to a method for preventing deformation and cracking of pine wood. Background technique [0002] Pine wood has the characteristics of pine fragrance, light yellow color, many boils, quick response to atmospheric temperature, easy to swell, and extremely difficult to dry naturally. Cracking; however, most of the current methods to prevent pine deformation and cracking use toxic chemical reagents, and the process is complicated. While delaying the deformation and cracking of pine furniture, it will also endanger human health during the preparation and use of furniture. Therefore, a safe A healthy, simple and efficient method to prevent deformation and cracking of pine wood. Contents of the invention [0003] In order to make up for the defects of the prior art, the purpose of the present invention is to provide a method for preventing deformation and cracking ...
