Wood preservative is used after curing wood preservative penetration and let the wood has to prevent decay function and biological damage features of the wood. Because wood preservative has antiseptic effect, so more will be used as outdoor flooring materials. Anticorrosive wood floor can effectively prevent the erosion of the microorganism, but also prevent infestation, and waterproof, anti-corrosion, so it can withstand outdoor relatively harsh environment, do not bother to take care of.
Anticorrosive wood now domestic rare mainly have two kinds of material: Russian and Nordic pine Pinus sylvestris var. mongolica. Russian Pinus sylvestris material anticorrosive wood is mainly wood preservative treatment of imported logs do at home, much as CCA agent disposal. North Akamatsu material is anticorrosive wood by foreign good anti-corrosion treatment, anti-corrosion timber import to domestic direct sales, and now are ACQ reagent disposal, and is often called "Finland wood" as the domestic wood preservative is most early over imported from Finland people accustomed to the preservation of wood called Finland wood, in fact, this is wrong it is easy to make people don't understand anticorrosive wood misunderstood.
Wood floor is the main defense rot of Pinus sylvestris var.mongolica Pinus sylvestris, fine quality, straight texture, the anti-corrosion treatment, can effectively prevent mold, termites, microbial invasion borers, can effectively inhibit the disposition change of wood moisture content, reduce the fracture level wood, let the outdoor anticorrosive wood more durable, so that the wood preservative to prolong the service life. Pinus sylvestris var. mongolica distributed mainly in the summer Liangdong cold with proper precipitation climate condition, distribution in Heilongjiang Greater Khingan Range North local mountain, Inner Mongolia Hailar and west of the Xingan mountains, Russia's rich in natural resources of Pinus sylvestris var. mongolica.
Because the chemical anticorrosive wood contains chemicals harmful to human and livestock, so chemical anticorrosive wood needs special disposal after use, thereby increasing the use of capital. In addition, chemical anticorrosive wood can not be recycled, thereby wasting wood resources. The effectiveness of wood preservatives are mainly determined by the toxicity of harmful organisms for biological toxicity hazard wood is bigger, the stronger the antiseptic effect. In general, the wood must be joined to other agents, one is from corrosion, but also can enhance the wood stiffness, strength, durability.
Buy wood preservative, don't just look at the color and appearance, should focus on to see the drug loading and depth of penetration. A wood preservative CCA -C wood preservative treatment as an example, if used in outdoor, but do not touch the ground, wood preservative should reach loading need is greater than or equal to 4 kg / m3, penetration depth should be greater than or equal to 85%; if used in outdoor, ground contact or immersion in fresh water, anti rotten wood should reach the drug loading needs to be greater than or equal to 9.6 kg / m3, penetration depth should be greater than or equal to 95%. From the appearance of color, wood preservative generally appear green or blue green, this is because the CCA or ACQ wood preservatives containing copper oxide. But the color is actually not the main quality indexes of wood preservative. It should be pointed out some illegal manufacturers by soaking, even qualified by posing as palette simple methods such as wood preservative. For these products the consumer must identify.
Buy wood preservative must choose product inspection certificate of anticorrosive wood. Especially for bulk purchase or temporary purchase wood preservative of users, but it is not the technical means of anticorrosive wood quality verification, to find the best specialized in wood preservative quality inspection institutions for quality verification, quality detection of speech.
