Outdoor bamboo flooring is a special kind of artificial board, which requires higher processing accuracy and aesthetics than other artificial boards. Therefore, the production processes usually adopted by bamboo floor manufacturers are:
Select fresh, four-year-old raw bamboo according to the preset length and cut it into bamboo tubes with a cutting machine. When cutting materials, attention should be paid to the selection of materials to improve the utilization rate of bamboo materials and reduce production costs.
The bamboo tube cut by the cutting machine is sawed with a coaxial double saw blade slicer to obtain bamboo chips of equal width and length. The width of the bamboo chips is determined by the interval between the saw blades and can be adjusted as required.
3. Rough planing (rough smoothing on all sides)
The bamboo chips after sawing and separating the bamboo tube are actually a section of the arc of the bamboo tube. In order to facilitate subsequent processing, the bamboo outer skin and tabasheer on both sides of the bamboo chip must be removed and processed into a rectangular bamboo chip as its section shape.
Bamboo contains more nutrients than ordinary wood. These organic substances are the best nutrients for insects and microorganisms (fungi). Therefore, it is easy to be damaged by worms and mildew to be used and stored under suitable temperature and humidity conditions. The rot and mildew of bamboo are mainly caused by the parasitism of decaying bacteria, which can easily occur under the humid and hot conditions with poor ventilation. However, outdoor bamboo flooring has a long service life, high appearance requirements and poor using environment, and it will inevitably affect its service life if it is not treated or treated poorly. Therefore, outdoor bamboo flooring must solve the problem of insect and mildew prevention first.
The principle of carbonization is to place bamboo chips in a high temperature, high humidity, and high pressure environment to decompose and denature the organic compounds in the bamboo, such as sugar, starch, and protein, so that moths and molds lose their source of nutrients, and the eggs and fungi are killed at the same time. After the bamboo material is subjected to high temperature and high pressure, the bamboo fiber is coked into a bronze color or a color similar to coffee. The carbonized flooring is antique in color and unique. Since there is no soluble organic matter precipitated during the carbonization process, the carbonized bamboo flakes are larger than the steamed bamboo flakes. At the same time, due to the coking of bamboo fiber, the surface hardness of bamboo is increased, but the flexibility of bamboo is reduced.
