防腐木分为哪几种状态?

来源:http://www.jnajgc.com 时间:2022-05-09

防腐木的状态可以分为绝干状态,纤维饱和状态,生材状态,气干状态四种。
The state of preservative wood can be divided into four types: absolutely dry state, fiber saturated state, green wood state and air dry state.
绝干状态:当木材中的自由水和结合水完全被除去时木材的状态称为绝干状态,纤维饱和状态:纤维饱和点是一个临界状态,一般自由水的量对木材的物理性质影响不大,而结合水含量的多少对木材的各项物理力学性质有很大的影响。
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.
防腐木生材状态:刚砍伐下来的木材处于生材状态,细胞腔和细胞壁中都含有水,自由水的量随着季节变化,结合水处于饱和状态。
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.
气干状态:当把生材放在大气环境中自然干燥,达到的水分平衡状态称为气干状态,一般来说,中国南方地区的气干含水率较高,大约为15%~16%,而北方地区则在12%~13%左右。
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%.
防腐木为什么会有防腐木色差。
Why does antiseptic wood have color difference.
密度高,强度高,握钉力好,纹理清晰非常具有装饰效果防止木材在户外环境中腐烂抗白蚁等虫害的侵蚀抗真类生物的侵蚀,防霉变防止水生(淡水,海水)寄生虫的寄生,可大量应用于水景成型产品,可直接安装,且维护方便ACQ处理,环保,可全球林业增长不易变形或开裂经济耐用,美观得体。
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.
为什么说木防腐木材的变形与开裂与含水率有关。
Why is the deformation and cracking of wood preservative wood related to moisture content.
木材做为一种材料,开裂是由于含水率及木质年轮不同等多种原因而产生的,属于正常现象,防腐剂做为一种防腐材料,其目的在于防腐,使木材置于室外的恶劣环境中可以抵制白蚁侵蚀,孢子的生长与腐朽,水生生物的寄宿以及其他昆虫的繁殖,的延长木质在自然环境下的使用时间。
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.
