Embodiment 1

[0018] A mildew-proof and moth-proof treatment method for poplar, comprising the following steps:

[0019] (1) Heating and steaming: put the poplar in the steam and steam for 30 minutes, the instant high temperature kills the bacteria inside and on the surface of the poplar, inhibits mold and insects, takes it out, cools it down to 40~45°C, and it can be loosened Fiber structure, increase the softness of poplar, reduce the occurrence of cracking, and steam poplar;

[0020] (2) Freeze-drying: freeze-dry the steamed poplar at -38°C until the water content is 20-22%, increase the fine pore structure inside the poplar, increase the air content, facilitate the loss of water, and inhibit the growth of mold. The fine pore structure can increase the degree of deformation of poplar, increase softness, reduce brittleness, reduce cracking and deformation, and obtain freshly dried poplar;

[0021] (3) Soaking and sterilization: put the newly dried poplar in the soaking solution, soak at ...

Embodiment 2

[0030] A mildew-proof and moth-proof treatment method for poplar, comprising the following steps:

[0031] (1) Heating and steaming: put the poplar wood in steam for 30 minutes, the instant high temperature will kill the bacteria inside and on the surface of the poplar wood, inhibit mildew and insects, take it out, cool it down to 40~45℃, it can be loosened Fiber structure, increase the softness of poplar, reduce the occurrence of cracking, and steam poplar;

[0032] (2) Freeze-drying: freeze-dry the steamed poplar at -37°C until the water content is 20-22%, increase the fine pore structure inside the poplar, increase the air content, facilitate the loss of water, and inhibit the growth of mold. The fine pore structure can increase the degree of deformation of poplar, increase softness, reduce brittleness, reduce cracking and deformation, and obtain freshly dried poplar;

[0033] (3) Soak and sterilize: put the freshly dried poplar in the soaking solution, soak at a constant ...

Embodiment 3

[0042] A mildew-proof and moth-proof treatment method for poplar, comprising the following steps:

[0043] (1) Heating and steaming: put the poplar wood in the steam and steam it for 35 minutes, the instant high temperature kills the bacteria inside and on the surface of the poplar wood, inhibits mold and insects, takes it out, cools it down to 40~45°C, and it can be loosened Fiber structure, increase the softness of poplar, reduce the occurrence of cracking, and steam poplar;

[0044] (2) Freeze-drying: freeze-dry the steamed poplar at -36°C until the water content is 20-22%, increase the fine pore structure inside the poplar, increase the air content, facilitate the loss of water, and inhibit the growth of mold. The fine pore structure can increase the degree of deformation of poplar, increase softness, reduce brittleness, reduce cracking and deformation, and obtain freshly dried poplar;

[0045] (3) Soaking and sterilization: put the newly dried poplar in the soaking solut...

Abstract

The invention mainly relates to the field of wood treatment, and discloses a mould-proof and moth-proof treatment method for poplar. The method includes the steps of heating steaming, freeze drying, soaking for sterilization and heating curing. The method is simple, no harmful chemical components are contained, the bacteriostasis rate of the poplar is made to reach 76.3%, storage and usage are facilitated, the service life is prolonged by 16.2%, losses caused by mildew and damage by worms are reduced, and the economic income is increased by 7.6%. The poplar is placed into steam for steaming, a flash high temperature is obtained to kill infectious microbes inside the poplar and on the surface of the poplar, and the phenomenon of mildew and damage by worms can be restrained; and meanwhile, the temperature is lowered gradually after the flash high temperature, the filter structure can be loosened, softness of the poplar is improved, and the cracking phenomenon is reduced. The poplar is subjected to freeze drying, the dense air pore structure inside the poplar is added, the air content is increased, moisture missing is facilitated, and mould growth is inhibited; and meanwhile, due to the dense air pore structure, the deformation degree of the poplar can be raised, the softness is improved, the brittleness is lowered, and cracking and deformation are reduced.

Description

technical field [0001] The invention mainly relates to the field of wood treatment, in particular to a mildew-proof and moth-proof treatment method for poplar. Background technique [0002] Poplar, also known as "small leaf poplar", often has a luster like a joke, so it is also called "satin poplar". It is a wood commonly used in northern my country. It is soft, stable, cheap and easy to get, and is very popular among consumers. one of the wood. However, poplar is easy to deform, loves long insects, and is easy to be moldy and insect-eaten. In the current treatment process of poplar, in order to prevent moldy and insect-eaten, it is treated with various chemical reagents, which is easy to cause damage to the environment and human body. Therefore, a safe Anti-mold and anti-moth treatment methods for healthy poplar. Contents of the invention [0003] In order to make up for the defects of the prior art, the object of the invention is to provide a mildew-proof and moth-proof...
