Description

Mildew-proof treatment device and method for small bamboos

Technical Field

The invention relates to the technical field of bamboo product processing, in particular to a mildew-proof treatment device and method for small bamboos.

Background

The bamboo weaving is to weave bamboo into various furniture, living goods and artworks by processing bamboo into bamboo filaments, bamboo strips and bamboo chips. The bamboo weaving process in China has long history, abundant raw materials and various products, can be used for producing articles for daily use and is convenient for daily life of people, can also be made into high-grade bamboo weaving artworks, and has artistic appreciation and collection values and very wide market prospect.

In the process of bamboo weaving, the small bamboo is used as a raw material, the problems of fading, mildew, worm damage and the like are easy to occur, the usability and the ornamental value of bamboo weaving furniture products and handicraft products are influenced, and therefore the bamboo weaving can be carried out only after the small bamboo raw material is subjected to cutting, cleaning, mildew-proof treatment and drying treatment in sequence. At present, the mildew-proof treatment of the small bamboos is mainly divided into two methods, wherein the small bamboos are placed at high temperature through high-temperature sterilization to effectively kill mildew and moth on the surfaces, but the high-temperature sterilization only can kill germs on the surfaces and cannot achieve the long-term mildew-proof effect; the second way is sterilization by soaking with chemical mildew inhibitor, although the method can permeate the mildew inhibitor into the bamboo surface to improve the mildew-proof period, the chemical mildew inhibitor is easy to attach to the small bamboo, and is unsafe and environment-friendly. For example, patent No. CN108943233A discloses a method for mildew-proof treatment of bamboo, comprising the following steps: cleaning bamboo, cutting into sections, soaking, air drying, and performing microwave treatment to obtain a material A; adding the material A into an insect-proof and mildew-proof agent for soaking, taking out, draining, and drying to obtain a material B; soaking the material B in titanium sol, taking out and putting into an oven, controlling the temperature, washing and annealing to obtain a material C; dissolving zinc acetate and sodium hydroxide in methanol to prepare a mixed solution, soaking bamboo wood in the mixed solution, taking out, and annealing to obtain a material D; then, dissolving zinc nitrate and hexamethylenetetramine in water to prepare an aqueous solution A, and then soaking, washing and annealing the material D in the aqueous solution A. Although the mildew-proof treatment method disclosed by the invention improves the mildew-proof effect of the bamboo to a certain extent, the chemical mildew-proof agent exists on the surface of the bamboo for a long time and has certain harm to the health of a human body.
