The state of preservative wood can be divided into four types: absolutely dry state, fiber saturated state, green wood state and air dry state.
Absolute dry state: when the free water and combined water in wood are completely removed, the state of wood is called absolute dry state. Fiber saturation state: the fiber saturation point is a critical state. Generally, the amount of free water has little effect on the physical properties of wood, while the content of combined water has a great effect on the physical and mechanical properties of wood.
Green wood state of preservative wood: the newly cut wood is in green wood state, and the cell cavity and cell wall contain water. The amount of free water changes with seasons, and the combined water is saturated.
Air dry state: when the raw wood is naturally dried in the atmospheric environment, the water balance state is called air dry state. Generally speaking, the air dry moisture content in southern China is high, about 15% ~ 16%, while that in northern China is about 12% ~ 13%.
Why does antiseptic wood have color difference.
High density, high strength, good nail holding force, clear texture, very decorative effect, prevent wood from rotting in the outdoor environment, resist the erosion of termites and other pests, resist the erosion of real organisms, prevent mildew and prevent the parasitism of aquatic (fresh water, sea water) parasites. It can be widely used in Waterscape products. It can be directly installed and easy to maintain. ACQ treatment is environmentally friendly, and it can prevent global forestry growth from deformation or cracking. It is economical, durable and beautiful.
Why is the deformation and cracking of wood preservative wood related to moisture content.
As a material, wood cracking is caused by various reasons such as different moisture content and wood rings, which is a normal phenomenon. As an anti-corrosion material, the purpose of preservative is to prevent corrosion, so that the wood can resist termite erosion, the growth and decay of spores, the boarding of aquatic organisms and the reproduction of other insects in the harsh outdoor environment, and prolong the service time of wood in the natural environment.
