Selection of anti-corrosion wood in courtyard design
With the gradual deepening of courtyard design, there are also various types of wood usage. Anticorrosive wood has also played an important role in the construction of yards, villas, gardens, and roof gardens. Anticorrosive wood is still a relatively new product at present, and it is indeed a difficult problem for consumers who have just come into contact with it to identify their quality. Here is a simple introduction to help them make a better choice.
The simple way to identify the quality of raw materials is to look at it intuitively. The finer the annual rings of the wood, the better the raw material is. Because the finer annual rings indicate that the wood grows slowly, in short, the wood that does not look so chaffy from the cross section should be thicker. Good wood.
The way to identify the quality of wood processing is to first look at the overall quality of the wood to see if it is of correct size and regular without much error. Generally, the error of thinner boards should be smaller than that of larger materials, and the overall error of larger materials should not be greater than. Generally, the materials that pass through the production line are standard and there is no error at all. However, the materials that are hand-processed have larger errors, which will cause difficulty in construction. In addition, regarding the planed material, you also need to pay attention to the quality of the surface planing, which is smooth and natural.
r Method to identify the stability of wood preservatives: Take samples of different preservative wood and soak them in clean water of the same temperature and volume. After the same soaking time, observe the color of the water. The color change is minimal. , should be the one with the best preservative stability. This is not a definitely accurate method, as the preservative concentration at the time of disposal may also make some difference. After the wood has been preservative treated, the stability of the wood itself varies greatly due to the use of different preservatives. After pressure treatment, its stability in the wood is also greatly different. The use of preservatives of substandard quality will have a negative impact on the preservative function of the wood. Not much improvement, but serious potential damage.
r Methods to identify the quality of wood preservative and pressure treatment (the sapwood is fully immersed in the preservative, and the surface is clean and uniform). For European Scots pine, from the cross-section of the wood, the quality is better when the preservative is fully immersed in the sapwood. , because some of the heartwood of this tree species is naturally durable. But most other tree species should usually be thoroughly soaked in preservatives.
