How does Hunan anticorrosive wood flower stand identify the quality of anticorrosive wood on the market?
1. A simple way to identify the quality of the material (not "bran" is better). From an intuitive point of view, the finer the wood growth rings, the better the material is, because the fine growth rings indicate that the wood grows slowly. Simply put, it doesn't look that way from the cut surface. "Bran" wood should be a better wood.
2. The method of identifying the quality of wood processing (uniform specifications, small errors, good processing quality) can first look at the wood as a whole to see if the specifications are correct and tidy without much error. Generally, the error of thinner plates should be less than 0.5-1mm; larger specifications The overall error of the material should not be greater than 2mm. Generally, the material under the production line has a neat specification and basically no error. However, the manual processing material has a large error, which will cause construction difficulty. In addition, for planed materials, you also need to look at the quality of surface planing. Smooth and natural is better.
3. The method to identify the stability of wood preservatives (the color of the soaking water is the smallest, and the preservative is stable). Take samples of different preservative woods (same specifications and the same moisture content) and soak them at the same temperature and the same volume. After the same soaking time in clear water, obse
