How long can the natural bamboo fence be used?
bamboo fences Because of its natural material, the service life of bamboo fence will be affected by many factors. In general, natural bamboo fences without special treatment are used for a relatively short time, usually around 3 to 5 years. However, if bamboo is properly treated and protected, its service life can be greatly extended.
First, the factors affecting the service life of natural bamboo fence
The natural properties of bamboo
Bamboo itself has a certain durability, but it is susceptible to biodegradation in the natural environment. For example, bamboo can be eroded by fungi, bacteria and insects, reducing its useful life
The moisture content of bamboo also affects its useful life. If the moisture content of bamboo is too high, it will easily lead to rot and mildew; If the moisture content is too low, it may become fragile and brittle.
Environmental factor
Climatic conditions are one of the important factors affecting the service life of natural bamboo fences. In a humid environment, bamboo is more susceptible to corrosion and mildew; In a dry environment, bamboo can become dry and crack.
Sun exposure can also have an effect on bamboo. After prolonged exposure to sunlight, bamboo may become discolored and brittle, reducing its service life.
In addition, wind, rain, snow and other natural factors will also cause certain damage to bamboo fences.
Bamboo weathering is mainly caused by the following factors:
First, physical factors
Temperature change
Bamboo undergoes day-night and seasonal temperature changes in its natural environment. When the temperature rises, the water inside the bamboo evaporates, causing the bamboo to shrink; When the temperature drops, the bamboo absorbs moisture from the air and expands. This repeated process of thermal expansion and contraction will gradually damage the structure of the bamboo. For example, in the hot day, the water in the bamboo fiber quickly dissipates, and the bamboo becomes dry and brittle; When the temperature drops at night, the bamboo absorbs some water. In this cycle, the connections between the bamboo fibers become loose, and eventually cracks appear on the surface of the bamboo, which is a sign of weathering.
Here are some common bamboo fence treatment methods:
First, anti-corrosion treatment
Chemical preservation
Soaking method:
Soak the bamboo in a solution containing preservatives. For example, a copper chromium-arsenic (CCA) antiseptic solution is used, which effectively inhibits fungus, bacteria and insects from attacking bamboo. The soaking time generally depends on the size of the bamboo and the concentration of the preservative, and usually requires soaking for 24-72 hours. During the soaking process, preservatives penetrate deep into the bamboo's inner fibers, forming a protective layer. However, because CCA contains heavy metals, its use may be limited in some occasions with high environmental requirements.
Painting method:
Choose a suitable preservative, such as environmentally friendly cuprizole (CA) preservative, and use a brush to evenly paint the preservative on the surface of the bamboo. This method is simple to operate, but the preservative penetration depth is relatively shallow. Generally, it is necessary to brush 2-3 times to ensure that the surface of the bamboo is completely covered.
Physical corrosion protection
Heat treatment:
The purpose of preservative is to cook bamboo at high temperature. The bamboo is put into a special cooking equipment and cooked at a high temperature of 180-230 ° C for 1-3 hours. This process kills pests such as eggs, fungi and bacteria inside the bamboo, while also denaturing nutrients such as starch in the bamboo
Why choose synthetic bamboo fence
The service life of synthetic bamboo fence is usually about 10-20 years, but the specific service life will be affected by a variety of factors, including the quality of raw materials, production process, installation method, use environment and so on.
Raw material quality: If the use of high-quality synthetic materials, with good weather resistance, aging resistance and corrosion resistance, then the service life of synthetic bamboo fence will be relatively long. For example, the use of high-quality plastic or composite materials made of synthetic bamboo fence, its performance is more stable, not easily affected by the external environment.
Production process: The advanced production process can make the structure of the synthetic bamboo fence more solid and the surface treatment more fine, thus improving its service life. For example, some synthetic bamboo fences that have been treated by special processes have better waterproof, moisture-proof and insect-proof properties, and can also maintain a better state in harsh environments.
Installation method: The correct installation can ensure the stability and firmness of the synthetic bamboo fence, reduce the damage caused by loosening, deformation and other problems, so as to extend the service life. When installing, ensure the depth and verticality of the column, as well as the connection between the fence and the column.
The use of environment: in a more moderate environment, such as dry climate, moderate sunshine, no severe weather areas such as strong winds and storms, the service life of synthetic bamboo fences will be longer
