As an outdoor floor, it must be able to withstand the changing weather of the outdoors, and the strong temperature difference, which is very high for outdoor wood flooring. To become a leader in outdoor flooring, it is generally necessary to have the following A few basic conditions:
1. Strong stability: ordinary wood flooring has relatively large hygroscopicity. It is easy to be deformed when it is washed by rain and snow outdoors. It is not a long-term solution;
2, strong corrosion resistance: outdoor rain is sufficient, easy to breed fungi and termites, wood corrosion rate is faster;
3, strong pressure resistance: many people walking outdoors, the floor is required to resist pressure according to the characteristics of the outdoor floor, the material suitable for outdoor flooring is carbonized wood.
Carbonized wood technology has not developed rapidly in China, but it is already a mature technology in foreign countries. Many countries use carbonized wood. In China's public facilities, there is no widespread use of carbonized wood in outdoor flooring. Most of the flooring used are composite flooring, laminate flooring, solid wood flooring, etc. These floorings are not resistant to corrosion and are easily deformed under outdoor conditions. Cracked, faded.
The technology of carbonized wood technology in China is not mature. The earliest research is the Shiyou Carbonized Wood Division of Zhejiang Shiyou Wood Industry Co., Ltd., now renamed Meishu Meiting, specializing in the production of deep carbonized wood. The advantages of carbonized wood outdoor flooring are:
1. It is not easy to deform. The pyrolysis treatment of wood by ultra-high temperature reduces the concentration of hydroxyl groups in the wood components, thereby reducing the hygroscopicity and internal stress of the wood, and achieving the purpose of reducing wood deformation.
2, strong corrosion resistance by pyrolysis of wood by ultra-high temperature, wood components in the ultra-high temperature heat treatment process has a complex chemical reaction, changing some components of wood. On the one hand, it reduces the nutrients of wood decay bacteria, inhibits the growth of fungi in wood from the food chain, and improves the corrosion resistance of wood; on the other hand, complex chemical reactions occur in wood to produce some anti-corrosion bacteria. Harmful acidic substances inhibit the growth of decaying bacteria, thereby improving the corrosion resistance of wood.
3. Uniform color and luster The wood is pyrolyzed by ultra-high temperature, and the wood color is uniform. Some minerals inside the wood, after ultra-high temperature treatment, are analyzed to the surface of the wood and glow.
4. The texture is clear. The wood is pyrolyzed by ultra-high temperature. The wood is more obvious in the early and late wood, the annual ring is clear, the texture is natural and beautiful.
5, healthy, environmentally friendly carbonized wood does not add any chemical preservatives to ensure the health and environmental protection of charred wood, the skin can be directly exposed to charred wood.
6. Recyclable Because the charcoal wood is not added with any chemical ingredients during production and use, it is pure natural wood, which can be recycled, thus saving resources and reducing costs.
