Origin of Finnish wood

Feb. 8,2020

The Finnish wood that is usually referred to is actually a kind of antiseptic wood. Finnish anticorrosive wood at home is divided into two examples: original Finnish entrance and processing and disposal of imported materials. An important material is Pinus silvestris, an important development in Finland.

Finland is the country with the highest forest coverage in Northern Europe, and the world's forest coverage ranks second. Finland is one of the Nordic countries on Scandinavia, and it is the world's most favorable place for the development of high-quality wood. Extremely cold and long winters make it possible for trees to develop as long as about 100 days in a year, and the slow and average development cultivates the best wood. The wood is strong, the texture is average, and the trees are small and few. Low-resin, natural-textured Nordic wood has been the wood of choice in many industries for centuries, and is known as the "nordic green diamond." Finland is the country with the highest forest coverage in Northern Europe, and the global forest coverage ranks second. It is also the first country to export the preserved Nordic pine to China. It is customarily called the Nordic pine pine as "Finnish wood".

Nordic pine has a good layout function, the air-dry density is 0.54g / cm3 (the dry material content is about 540 kg / m3). The texture is average and precise, with good quality. Nordic Pinus koraiensis was developed in the severe cold region. It is a slow-growing tree species, with careful wood, low fat content, wood fiber texture, small knots, and higher strength than most softwood species.

Finnish wood is an outdoor anti-corrosion wood that is artificially preservative wood, treated with ACQ preservatives under pressure and KDAT (secondary kiln dried). Finnish preservatives are degreased in a vacuum, and the water-soluble preservative ACQ is injected in a closed low-pressure warehouse, so that the preservatives are dipped into the deep cells of the wood, so that the wood has antifungal, anticorrosive, termite and other parasitic effects, and High density, high strength, good nail holding force, clear texture and decoration effects.

Finnish wood adopts ACQ preservatives without arsenic and chromium. ACQ is the abbreviation for ammonia-soluble quaternary ammonia copper. ACQ preservative is a new environmentally friendly preservative developed rapidly. Compared with traditional CCA preservatives, ACQ does not contain heavy metal chromium and highly toxic arsenic, which has minimal impact on humans, animals and conditions, and has good antiseptic properties. Therefore, the preservative wood products treated with ACQ preservatives are a safe and environmentally friendly product.
