What is Scots Pine for Wood slide
Created on 08.22
The material properties and processing of wood have a direct impact on the quality and safety of wooden playground equipment. As the main preservative wood substrate in the market, due to the material and processing process of Russian Scots Pine has many advantages, it has become the first choice of children's playground equipment. For foreign friends, we must master the necessary performance and application of this wood to make the right purchase.
1. Russian Scots Pine.
Russian Scots Pine is not a independent tree species, but a geographical variety of Scots Pine (Pinus sylvestris var. mongolica) in the Pinaceae family. It is widely distributed in the cold temperate forest area of Siberia, Russia. Long and cold winters and short summers make Russian Scots Pine a long slow growth cycle in the growth process, the wood structure is fine and the growth ring is obvious. This dense wood structure is formed in the cold climate,better bending and compressive strength than many fast growing pine trees, laying a good foundation for the service life of wood playground equipment.
2. Core Advantage.
Russian Scots Pine's dominant position in the antiseptic wooden playground equipment field is due to its multi advantages. The first is that it has excellent bearing capacity, whether as the climbing frame's load-bearing beam or the supporting frame of the outdoor slide can be used for a long time. The second is that it has excellent processing properties. The grain of the wood is straight, the hardness is moderate, the texture is uniform, and the cutting, grinding, drilling and splicing processes are relatively convenient, which can meet precise and diverse playground equipment design requirements, from curved ladders to hollow platforms. The most important is that the wood has excellent corrosion resistance. Although its own corrosion resistance is not enough, the porous cellular structure of wood allows preservatives to penetrate the wood tissue evenly and deeply under pressure, and the pressure enhances the efficiency and performance of anti-corrosion treatment, providing reliable protection for long-term exposure to the air.
3. Appearance.
Untreated Russian Scots Pine shows the natural beauty of pine: the main body of wood is elegant pale yellow to light yellow brown, and there are clear and fine growth rings on the surface, which is the result of slow growth. The texture is uniform and the gloss is soft, making the wood appear rustic and warm. After carbonization at high temperature and high pressure, the color turns dark brown or tan, showing the growth rings. The carbonized part on the surface of the wood enhances the anti-corrosion performance of the wood, and the retro appearance brings visual effects. Wood pressure treated with environmentally friendly preservatives such as ACQ will retain most of its original natural color, just slightly darker than untreated wood, but the texture remains fine. It is worth noting that Scots Pine can be polished to a very fine and smooth surface after processing, effectively avoiding the safety hazards of burrs and splinters, and it is particularly suitable for use in kid playground equipment and children's furniture that contact children's skin.
4. Anti-corrosion treatment.
The two main treatment process in the industry focus on their own field.
Carbonization: The habitat of decay fungi in the wood is damaged by high temperature and high pressure. In addition to improving the anti-corrosion and insect-killing performance, it can also improve the dimensional stability, and the cracking and deformation in the humid-dry environment outdoors will be reduced.
Pressure Infusion: This is a more common way. Environmentally friendly preservatives ACQ (alkyl copper ammonium compounds) are infused into the wood under high pressure into the deep wood, forming a durable bioprotective layer to resist the attack of fungi and mold, decay fungi and termites, greatly extending the service life of the equipment.
Fir treated in this way maintains its original warmth and beautiful view and has very good anti-outdoor environment durability. The surface is smooth and will not scratch children. The structure is stable and safe for a long time, which is the best material for outdoor playground equipment.
