In the face of the harsh external environment, ordinary wood can not resist the erosion of mold, rain, etc., and is extremely perishable. The anti-corrosion wood after the poisoning of the wood with preservatives can prevent the decaying function of the wood decaying wood. It is under vacuum, the antiseptic agent is immersed in the wood tissue cells by high pressure, closely mixed with its cell fibrous tissue, and the drug is not released.
At present, the preservative mainly has CCA/ACQ, the main component of CCA is copper arsenic, and the main component of ACQ is ammonia-soluble alkylamine copper. Because it retains the same characteristics, color and texture as ordinary wood, it is widely used in outdoor gardening environments.
In fact, in addition to anti-corrosion, anti-corrosion wood has three basic functions of preventing termites, fungi and corrosion. Anti-corrosion wood also has the characteristics of good permeability and strong resistance to leaching. At the same time, it can also inhibit the change of moisture content of treated wood and reduce the degree of wood cracking.
Due to the infusion of the agent during the pressurization process, the wood will have a slightly greenish chemical color, and the color is uneven, the color difference is large and dull, and it is easy to become gray and black with the loss of chemical agents. Generally, secondary drying is not taken, and the wood itself has a high water content, so that deformation and cracking are liable to occur.
Scope of application:
Outdoor courtyard, Ground platforms, guardrails, pavilions, rattan frames, tables and chairs, sketches, etc.
