Vacuum high-pressure soaking is the key link of Jiangxi anticorrosive wood railing. By injecting preservatives into wood, it can kill biological components such as starch, cellulose, sugar, etc., further destroy the living environment of bacteria, pests and diseases, and improve its antiseptic performance. High-temperature characteristics High-temperature qualitativeness is a further improvement of Jiangxi anticorrosive wood railings based on vacuum and high-pressure soaking. At high temperatures, preservatives can effectively and deeply penetrate into the interior of the fence, continuously ending the possible biological decay components in the wood, and continuously compressing and even eliminating the growth space of pests and bacteria. Natural air drying Natural air drying has two functions. The first is to stabilize the performance of the preservative in the first two stages and continuously distribute the excess preservative; the second is to adapt the anticorrosive wood fence to the future use environment, and form a stable wooden unit layout as soon as possible to adapt to future use. Natural air drying is usually the last step in the preservative treatment of wooden fences, and its stability is related to the end use of wooden fences. Anticorrosive wood fences are generally put into use directly through natural air drying.
