What Are The Characteristics Of Outdoor Furniture Wood

- Apr 18, 2020-

With the pursuit of the quality of outdoor leisure life, outdoor wood products, outdoor furniture, and forest building sketches are becoming more and more abundant. Outdoor furniture is an important element for coordinating people and cities, people and natural environment in outdoor public spaces. It can improve the quality of outdoor activities and provide places for people to relax.

The outdoor environment changes a lot, which makes outdoor furniture exposed to the outdoor for a long time to face rain, sunlight, insect pests and other attacks. Ordinary wood can not resist these long-term natural erosion. This has prompted experts to carry out a large number of researches on new types of outdoor wood, including composite wood-plastic materials, anti-corrosion wood treated with chemical agents, and carbonized wood treated with high temperature. These new outdoor furniture wood can effectively extend its service life, making it more suitable for outdoor space environment.

Outdoor furniture wood requirements

In order to allow outdoor furniture to better adapt to the outdoor environment and allow people to relax and comfortable activities in the outdoor environment, usually outdoor furniture wood has the following requirements:

1. Long service life and high durability

Compared with indoor furniture, the most prominent feature of outdoor furniture is that it has good durability in outdoor environments, resists the erosion of rain and the exposure of sunlight, and prevents the furniture from cracking and deformation under the erosion of harsh outdoor environments for a long time. This is the most basic and the most critical requirement for outdoor furniture. Only when the durability is guaranteed can good quality be achieved.

2. Stable reinforcement method

Because outdoor furniture is generally placed in public spaces for people to entertain and relax, it is not often necessary to move furniture, so the furniture fixing structure needs special consideration, it is necessary to prevent the furniture from tilting or collapsing, and to ensure that the connecting parts are exposed to the It will not be easily destroyed after rain.

3. Regular maintenance and repair

Outdoor furniture also needs regular maintenance and repair. In addition to cleaning up the dust, it is necessary to avoid sun exposure in summer and rain erosion during the rainy season. If you do not use it for a long time, it is best to cover the furniture with a protective cover.

Outdoor furniture wood

Solid wood outdoor furniture is usually made of wood that is not easily cracked, deformed and discolored by moths in outdoor environments. Such as teak, ash, etc., these wood materials are tough, thick structure, easy to process.

However, solid wood resources are limited after all. In order to allow outdoor furniture wood to have good performance and to slow down the contradiction between supply and demand of wood resources, researchers have developed outdoor wood products.

1. Antiseptic wood

Anti-corrosion wood is to add ordinary wood with chemical preservatives, so as to achieve anti-corrosion, moisture-proof, fungus-proof, waterproof, insect-proof and other effects. There are two general treatment methods for anti-corrosion wood, namely high-pressure dipping tank treatment and non-pressure dipping tank treatment. Among them, the high-pressure dipping method is the most commonly used. This method is to add preservatives after drying, curing, and polishing the wood and react under vacuum to allow the preservatives to enter the wood cells for permanent fixation to achieve the effect of anti-corrosion and insect control. .

The preservatives are mainly CCA whose chemical composition is chromated copper arsenate. The chemical properties of CCA are very stable, but because of the trace arsenic content may cause harm to the human body, most developed countries have now banned the use of this preservative. Another kind of preservative is ACQ whose main chemical component is alkyl copper ammonium compound. Its active substance is ammonium, which can be degraded and relatively has little pollution to the environment.

2. Carbonized wood

Carbonized wood is wood obtained by heat treatment in an inert gas, water vapor, or oil medium at 160 ° C to 250 ° C. This high-temperature treated wood can form a stable and entangled structure, which greatly improves the stability, and the volatilization of the extracts reduces the food of the decaying fungi, and improves the performance of antiseptic and antibacterial. Compared with the chemically modified anti-corrosion wood mentioned above, this modification method does not use chemical agents and is a more environmentally friendly modification method.

3. Wood-plastic composite materials

Wood-plastic composite materials are made of wood fiber or plant fiber, mixed with polyethylene, polypropylene, polyvinyl chloride and other polymer compounds, added with coupling agents and additives, and compounded through a series of processes. This kind of material has high hardness, high strength, degradability, and excellent waterproof and moisture proof performance, and can effectively prevent mildew and insects. It is an excellent outdoor furniture material.
