　　It is said to be anti-corrosion wooden tile strips. But at the construction site, it is common to see cedar strips brushing tung oil or asphalt hanging tile strips. Even if not brushed on site, chrome copper and ACQ will still be added to the factory storage tanks. The main component of copper chromate is copper, and the main component of ACQ is ammonia soluble alkylamine copper.

　　Over the past thirty years, the main method of anti-corrosion treatment for hanging tile strips has been CCA. It is mainly composed of Chromated Copper Aarsenate, which is clean and odorless. After treatment, the surface of the wood can be left unpainted. It is an internationally recognized and effective method for addressing anti-corrosion issues.

　　Arsenic appears in the form of CCA and has relatively stable chemical properties. After entering wood cells, it quickly fixes on wood fibers and forms insoluble compounds in water. It will not dry up with rainwater or soil moisture, nor will it dissolve in sweat or vomit. #Currently, most of the anti-corrosion wood manufacturers in China use CCA treatment for their products. More importantly, the upcoming Chinese anti-corrosion wood standards also clearly list various environmental and safety regulations in China that are completely consistent with CCA anti-corrosion impregnation treatment.

　　Therefore, ACQ gradually replaced American communication companies and became the mainstream in the market. The main chemical components of alkaline copper quaternary ammonium salts are alkyl copper ammonium compounds. Acq is one of the many new preservatives developed in the past decade. There is no arsenic in the raw material medicine. The ammonium in raw materials can decompose in nature, so its pollution to the environment is relatively small. However, it cannot be said that it is harmless to the environment because its main raw material is copper, and its waste cannot be treated by combustion. Wood must undergo special treatment.

　　The main issues are as follows: ACQ has poor anti-corrosion effect on white mold, and long-term use of ACQ may cause some mold deposition on the surface of wood. After ACQ anti-corrosion treatment, the permeability of the wood is difficult to meet the requirements, that is, the edges of the wood cannot be completely soaked. Therefore, ACQ treated wood is generally used in areas that do not come into contact with soil. There is a certain difference in the application effect between anti-corrosion wood without chromium arsenic treatment and anti-corrosion wood without chromium arsenic treatment. Sediments may appear on the surface of anti-corrosion wood without chromium arsenic treatment. We take TANALITH's E-type preservative and ACQ1900 as examples. Although many antifungal agents are added to the preservatives in the factory, it can still be found that the surface of these anti-corrosion woods is eroded by white rot fungi. ACQ is a new type of preservative. At present, research on it is not sufficient, especially its anti-corrosion ability has not been finally determined. Moreover, there is still a gap in the production process of ACQ wood preservatives produced in China compared to foreign countries, such as the problem of delamination not being fundamentally solved. At present, further research is needed on the use of ACQ
