Screening methods of Finnish wood and antiseptic wood in Guizhou

Screening methods of Finnish wood and antiseptic wood in Guizhou:

1. Screening the quality of wood processing:

Uniform specifications, small error and good processing quality. You can first see from the wood as a whole whether the specifications are correct and neat without much error. Generally, the error of thinner plates should be less than 0.5-1mm; the overall error of larger specifications should not be greater than 2mm. Generally through the materials under the production line, the specifications are neat and basically no errors. However, the materials processed by hand have large errors, which will cause difficulty in construction. In addition, for planing materials, you also need to look at the quality of the surface planing, it is better to be smooth and natural.

Second, identify the stability of wood preservatives:

The color change of the soaking water is the smallest, and the preservative has good stability. Take samples of different antiseptic woods (same specifications and same water content), and soak them in the same temperature and the same volume of clean water. After the same soaking time, observe the water color. The preservative with the smallest color change has the best stability. . This is not an absolutely accurate method, as preservative concentrations during processing can also vary widely. After the wood has undergone antiseptic treatment, the stability of the wood is greatly different due to the use of different preservatives. After pressure t
