Analysis of antiseptic wood fence preservatives
Now, we can see all kinds of antiseptic wood fences around us, and the arrival of it adds another beauty. In the process of use, the correct use of the method is very important. It is not understood by the antiseptic wood manufacturers that the antiseptic wood is used as a preservative to permeate and solidify wood to prevent the decay of rotten fungi.
In the past few decades, the main methods of the wood preservative treatment of anticorrosive wood manufacturers are CCA. The main chemical composition is chromic copper arsenate, which is clean and odorless, and the surface of the treated wood can be painted. High quality CCA agents have very stable properties, and their excellent anticorrosive properties make it widely used. Long term experience tells us that wood treated by CCA can be used in all kinds of harsh outdoor environments. It is an ideal anticorrosive agent for wood barrier protection. Because CCA contains extremely small amounts of arsenic,
So people began to worry about their mental health hazards. The United States began to stop using wood treated by CCA in January 1, 2004 (except for industrial and special environment). But at the same time, the United States' authority has made it clear that "there is no scientific evidence to prove that CCA is harmful to human health." It is clear that CCA is one of the antiseptic agents that can be applied in the industry standard of anticorrosion wood that will be announced in China.
