How to identify the quality of preservative wood

For the identification methods of anticorrosive wood, there are mainly several methods

1. Material quality identification:

From the visual point of view, the finer the ring material is, the better, because the ring density indicates that the wood grows slowly. In short, the wood that looks less "bran" from the cutting surface should be better.

2. To identify the quality of wood processing:

The specification is uniform, the error is small, and the processing quality is good. It can be seen from the overall wood whether the specification is correct and tidy without too much error. Generally, the error of thinner plate should be less than 0.5-1 mm; The overall error of larger size material should not be greater than 2mm. Generally through the birth

The material under production line is in order without error. However, the manual processing materials have a large error, which will cause the construction difficulty. In addition, for the planer, we need to see the quality of the surface planing, smooth and natural for good.

3. To identify the stability of wood preservatives:

The color of soaking water is small, and the preservative stability is good. Take samples of different anticorrosive wood (the same specification and the same moisture content), soak them in the same temperature and volume of water respectively. After the same soaking time, observe the color and color change of water

The stability of the smaller preservative is better. This is not an accurate method, as preservative concentrations may also vary significantly when treated. After the preservative treatment, the stability of wood is different because of the different preservatives. After being pressurized, it is in the wood

The stability of the wood is also different. The preservatives with high quality do not improve the anti-corrosion performance of wood, on the contrary, it will cause significant potential harm.

4. To identify the quality of wood anti-corrosion and pressure treatment:

The side material is fully immersed in preservative, and the surface is clean and even. From the aspect of wood cutting, the quality of preservative immersion in the sapwood is good, because the core wood part of the tree has natural durability, but most other species should be immersed in preservative.

5. Quality certificate of anti-corrosion and pressure treatment of wood: the quality of the anti-corrosion wood which can issue the test report is guaranteed.
