How to identify the environmental protection of preservatives used in preservative wood? Now please follow Xiaobian to understand it.
After preservative treatment, the stability of wood is different due to the use of different preservatives. Therefore, after pressure treatment, the stability of wood is also different. The use of poor quality preservatives does not greatly improve the preservative function of wood, on the contrary, it will cause serious potential damage.
Preservative wood is processed by preservative, but whether preservative is harmful to human body, and how to choose preservative processing is safer, these should be the most concerned problems of consumers. The early wood preservatives were CCA-C, B and other wood preservatives. Although this preservative has certain toxicity, it is only used outdoors, so it has less damage to human body. ACQ-D, C and B, which reach the European environmental protection standard, are used as preservatives for high-quality preservative wood, and their toxicity is almost zero, which enables consumers to purchase with their hearts fixed.
In general, the color change of soaking water is small, the preservative stability is good, that is more environmental protection. We can take different preservative wood samples (the same specifications, the same moisture content) and soak them in the same temperature, the same volume of water. After the same soaking time, we can observe the color of the water. The preservative with small color change has good stability. However, this is not a sure and accurate method, because the preservative concentration at the time of disposal can also vary greatly.
