Anti-corrosive wood is a kind of anti-rot, anti-termite, and anti-fungal effect. It is specially used for outdoor wood floor in outdoor environment, and can be directly used in the environment in contact with water and soil. It is outdoor wood floor, garden landscape floor, outdoor wood platform, terrace floor, outdoor wood plank and other outdoor anticorrosive wood pergola. Preferred material. At present, the main preservatives are CCA, ACQ, and CAB. The main component of CCA is copper arsenic, the main component of ACQ is copper salt of ammonia-soluble alkylamine, and the main component of CAB is copper file. Preservative wood determines the amount of preservatives according to the conditions of use. For details, see the recently issued national standard "Preservative Wood". There is also an antiseptic wood-deep carbonized wood without preservatives, also known as heat treated wood. Carbonized wood is used to carbonize the effective nutritional components of wood, and to achieve the purpose of antisepsis by cutting off the nutritional chain of decaying bacteria. It is a real green building material and environmentally friendly building material. The other is pure natural Canadian red cedar (Red Thuja) without any treatment, mainly by containing an enzyme inside, emitting a special fragrance to achieve the purpose of preservation. The main wood used in the anticorrosive flooring of our national defense floor is Pinus sylvestris var.mongolica, which is thin in texture and straight in texture. After antiseptic treatment, it can effectively prevent the invasion of mold, termites, and microorganisms, and can effectively inhibit Dealing with changes in the moisture content of wood, reducing the degree of cracking of the wood, making outdoor anticorrosive wood panels more durable and extending the service life of anticorrosive wood. Pinus sylvestris var.mongolica is mainly distributed in climatic conditions with cool summers and cold winters and appropriate precipitation. It is distributed in some mountainous areas in the Greater Xing'an Mountains, Heilongjiang, west of Hailar, Inner Mongolia, and northern Xiaoxing'an Mountains. Edit this paragraph The deep carbonized wood treatment process puts the agent into the wood by vacuum pressure and pressure. The wood is treated with high temperature treatment agent CCA, ACQ, CAB at about 200 degrees. No treatment cycle 4-6 hours 32-48 hours. Good, excellent, good dimensional stability second, better than teak hygroscopic swelling, second better than teak, good anti-corrosion and insect resistance, slightly worse, very good, quite use grade 2/3 grade anti-cracking performance outdoor use There will be cracking phenomenon, almost no cracking strength. Decrease about 40-70%. Limitations of use. Restricted use in places in contact with humans and animals. Unrestricted. Unrestricted. It is not recommended to use yellow, green, honey, and honey color of the carrier. Conditions, golden to brown. The wood preservatives in this paragraph are mainly CCA, ACQ, CAB. The main component of CCA is copper arsenic, the main component of ACQ is copper ammonia-soluble alkylamine, and the main component of CAB is copper file. Preservative wood determines the amount of preservatives according to the conditions of use. For details, see the recently issued national standard "Preservative Wood". For the past decades, CCA has been the main method of wood antiseptic treatment. Its main chemical component is Chromated Copper Aarsenate. It is clean and odorless. The treated wood surface can be painted. High-quality CCA agents have very stable characteristics, and their excellent antiseptic properties make them widely used. Long-term experience has taught us that CCA-treated wood can be used in a variety of harsh outdoor environments and is an ideal chemical preservative for wood protection. Due to the extremely trace amount of arsenic in CCA, people have recently become psychologically worried about its health hazards. The United States has stopped using CCA-treated wood (except industrial and special environmental aspects) on January 1, 2004. But at the same time, the authoritative organizations in the United States have clearly stated that "there is no scientific evidence to prove that CCA is harmful to human health. China's forthcoming industry standards for the application of anticorrosive wood specify that CCA is one of the anticorrosive agents that can be applied. ACQ ( The main chemical composition of Alkaline Copper Quaternary is an alkyl copper ammonium compound. It does not contain chemicals such as arsenic and chromium, has no adverse effects on the environment, and does not cause harm to humans, animals, fish, and plants. This treatment method is considered to be likely to become An effective alternative to CCA, but experiments have shown that ACQ is not as stable as CCA and is relatively easy to lose. At present, the cost is also nearly 20% higher than CCA. Therefore, from the domestic market perspective, the two methods of anticorrosive wood should coexist for a period of time. The continuous improvement of related technologies, in the long run, ACQ may become one of the main methods for the treatment of anticorrosive wood in the future.
