Embodiment 1

[0023] Poplar modified technique of the present invention comprises the following steps,

[0024] The first step is to test the material, and it is detected that the pH of the pretreated poplar is 5.5;

[0025] The second step is to peel and saw the poplar logs;

[0026] The third step, cooking: put 140 cubic meters of wood into a pool with 18.9 kg of sodium hydroxide solid particles, a water temperature of 40°C, and a water storage capacity of 126 tons, and cook for 15 days; the water is heated through a steam pipeline Constant temperature;

[0027] The fourth step is to drain the water in the pool first, then fill it with clear water at 5°C, and soak the poplar in clear water for two days;

[0028] The fifth step is to salvage the poplar and move it into the drying kiln;

[0029] The sixth step, drying: after the wood is put into the kiln, increase the temperature in the kiln to 20°C, keep it for one day, then increase it by 10°C every day, when it reaches 80°C, the tempe...

Embodiment 2

[0034] Poplar modified technique of the present invention comprises the following steps,

[0035] The first step is to test the material, and it is detected that the pH of the pretreated poplar is 7.8;

[0036] The second step is to peel and saw the poplar logs;

[0037] The third step, cooking: put 140 cubic meters of wood into a pool with a water temperature of 50°C and a water storage capacity of 155 tons, wherein the pool is added with 62 kg of hydrochloric acid solution with a mass fraction of 25%, and cook for 15 days;

[0038] The fourth step is to drain the water in the pool first, then fill it with clean water at 20°C, and soak the poplar in the clean water for two days;

[0039] The fifth step is to salvage the poplar and move it into the drying kiln;

[0040] The sixth step, drying: after the wood is put into the kiln, increase the temperature in the kiln to 20°C, keep it for one day, then increase it by 10°C every day, when it reaches 80°C, the temperature will n...

Abstract

The invention discloses a poplar modifying process, and belongs to the technical field of wood modification treatment. The poplar modifying process comprises processes of poplar acid-base property detection, stewing, wood acid-base neutralization, drying, adding a wood softener for modification, adjusting wood moisture content and the like. The poplar modifying process provided by the invention has the advantages that not only can the desired equipment be simple, but also large-scale production can be realized; and meanwhile, the effectiveness of the wood softener can be improved to the greatest extent, and the cost can be reduced.

Description

technical field [0001] The invention belongs to the technical field of wood modification treatment and relates to a poplar wood modification process. Background technique [0002] Influenced by foreign cultures, wooden residential buildings have appeared in many cities in China, and the trend is increasing year by year, and the demand for wood is increasing day by day. [0003] In today's increasingly tense timber resources, deforestation is becoming more and more serious. In order to reduce the damage to the natural forest, how to effectively utilize the wood produced by the artificial fast-growing poplar forest to make it have a wider range of applications is an effective way to alleviate the shortage of wood resources. [0004] Poplar has the advantages of short production cycle and high speed of becoming a material; but at the same time, it is not enough to be used as a structural material due to its disadvantages such as low density, poor material, and low strength. ...
