Antiseptic and mildewproof treatment technology for bamboo

Abstract

The invention belongs to the field of bamboo treatment and relates to an antiseptic and mildewproof treatment technology. The technology comprises the following steps that (1), the fresh bamboo is dried to be with the water content of 12-15%; (2), the dried bamboo is put into a vacuum pressure tank, the vacuum degree of the vacuum pressure tank is controlled to be over 0.08 MPa, and the treatment time ranges from 35 min to 50 min; (3), a protective agent is added to the vacuum pressure tank; (4), a vacuum pump is closed, a pressure pump is started, the pressure is made to be in the range of 1.2-1.8 MPa, and treatment is conducted for 50-70 min under the condition of keeping the pressure; and (5), the pressure is relieved, and the protective agent is drained. According to the antiseptic and mildewproof treatment technology for the bamboo, for the characteristic of the bamboo, the technological processes of drying, high-pressure, vacuum, pressurization and vacuum are adopted, in combination with the protective agent special for the bamboo, the protective agent can be effectively permeated into the bamboo from bamboo inner rings (inner of the bamboo) with the high nutrient content and the low density, the ideal protective agent saturation injection effect is achieved, the protective agent stays in the bamboo for a long time and is not easy to drain, and the long-term protective effect can be played.

Description

technical field [0001] The invention belongs to the field of bamboo and wood treatment, and relates to anti-corrosion and anti-mildew treatment, in particular to an anti-corrosion and anti-mildew treatment process. Background technique [0002] As one of the important raw materials for national construction and people's daily necessities, bamboo is widely used in the manufacture of building decoration materials and furniture because of its hardness, flexibility, straightness, compression resistance, tensile resistance, and corrosion resistance. The use of bamboo in the design, structure and materials of modern bamboo buildings is a highlight in the development of green buildings, which is in line with the concept of global sustainable development and the theme of low-carbon economy and low-carbon buildings in my country. my country is rich in bamboo resources. If a new type of bamboo structure wall can be developed, it will not only broaden the utilization range of bamboo, b...

Problems solved by technology

At present, the wood preservatives used in countries all over the world are mainly CCA preservatives. This kind of preservatives are toxic because they contain arsenic, chromium and other substances, which is not conducive to environmental protection. In some countries, their use has been strictly restricted.

The current anti-corrosion method is mainly aimed at the bamboo after splitting. It is applied to the original bamboo, the effect is poor, and the anti-corrosion effect is not obvious
