A Method for Preventing Cracking and Deformation of Poplar

Abstract

The invention mainly relates to the field of wood treatment, and discloses a method for preventing cotton wood from being cracked and deformed. The method comprises the steps of cotton wood wetting, cotton wood freeze drying, cotton wood peeling, cotton wood board wetting and cotton wood board drying. The method is simple, the water content of an obtained cotton wood board is 7-9%, the cotton wood is not likely to absorb water and is prevented from being cracked and deformed, the service life of the cotton wood is prolonged by 12.4%, and storage is convenient. The production cost is saved by 5.7%. The unpeeled cotton wood is wet by wetting liquid, and therefore the water content of the cotton wood is made uniform. Meanwhile, as cotton wood peel is not removed when wetted, the protection role of the cotton wood peel is brought into full play, the cotton wood is prevented from being expanded, and the fiber structure of the cotton wood is uniform and fine after the cotton wood absorbs water. In addition, the wetting liquid is formed by adding various Chinese herbal medicinal ingredients into wheat bran and wine yeast, the effective ingredients in traditional Chinese medicine are sufficiently extracted, bacteria resistance and pest killing are achieved, mildew and moths are prevented, no any chemical ingredient is contained, the method is safe and healthy, and the natural color and luster of the cotton wood are kept.

Description

technical field [0001] The invention mainly relates to the field of wood treatment, in particular to a method for preventing cracking and deformation of poplar wood. 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 wood is easy to deform, loves long insects, and is easy to crack. Poplar furniture that is strictly dried in a drying room is not easy to crack, but poplar wood is not easy to dry. There are many poplar boards on the market today due to many problems in cost or equipment. The drying is not in place, so the poplar furniture produced is prone to cracking and deformation. At present, in the process of poplar wood treatment, in order to prevent poplar wood from cracking and deformation, various chemical reagents are...

However, poplar wood is easy to deform, loves long insects, and is easy to crack. Poplar furniture that is strictly dried in a drying room is not easy to crack, but poplar wood is not easy to dry. There are many poplar boards on the market today due to many problems in cost or equipment. The drying is not in place, so the poplar furniture produced is prone to cracking and deformation. At present, in the process of poplar wood treatment, in order to prevent poplar wood from cracking and deformation, various chemical reagents are used for treatment, which is easy to damage the environment and human body. cause injury, therefore, there is a need for a safe and healthy method of preventing poplar wood from cracking and deforming
