Is anticorrosive wood poisonous? How can I tell?

   Anti-corrosion wood is made by artificially adding chemical preservatives to ordinary wood to make it have anti-corrosion, moisture-proof, anti-fungal, insect-proof, anti-mildew and waterproof properties. Able to directly touch the soil and humid environment. So are anticorrosive wood products and engineering harmful to the human body? Is anticorrosive wood poisonous? The following will tell everyone to reveal the answer!




Anticorrosive wood




The use of wood preservatives should be targeted at the appropriate objects (wood or wood-based panels or engineered wood), treated at the appropriate time (before decay and deterioration), select some preservative products, use appropriate concentrations, and adopt appropriate treatment methods , So that the wood reaches the correct amount of chemical retention, and the use environment of anti-corrosion treatment of wood products is correct (correct application).




At present, there are two main anti-corrosion treatment technologies for anti-corrosion wood processing, CCA anti-corrosion treatment, CCA, its main chemical composition is chromated copper arsenate, because CCA contains trace amounts of arsenic and heavy metal chromium, people have begun to worry about psychologically in recent years For its health hazards, the United States and the European Union have stopped using CCA at the beginning of this century; treated wood (except for industrial and special environmental aspects), in our use of CCA preservatives to treat wood preservation is still dominant.




   ACQ is the abbreviation of quaternary ammonium copper. It is mainly composed of copper oxide and quaternary ammonium salt. It does not contain arsenic and chromium. It is an environmentally friendly wood preservative with low toxicity to humans and animals. No adverse effects on the environment, this new type of environmentally friendly preservative will not cause harm to humans, livestock, fish and plants, and at the same time has good antiseptic properties. This treatment method is considered to be an alternative to CCA. With the continuous improvement of related technologies, ACQ may become one of the main methods of anti-corrosion wood treatment in the long run. Rongjing anticorrosive wood uses ACQ preservative processing. It can be said that the anticorrosive wood products treated with ACQ preservative are an environmentally friendly product.
