防腐木不适用于哪些地方?

来源:http://www.jnajgc.com 时间:2020-06-15

由于化学防腐木里面含有对人体和牲畜有害的化学药剂,所以化学防腐木使用完毕后需要专门处理,从而增加使用成本。另外,化学防腐木不能回收利用,从而浪费木材资源。济南防腐木教你如何辨别防腐木好坏。
As chemical preservative wood contains chemicals harmful to human body and livestock, it needs special treatment after use, thus increasing the use cost. In addition, chemical preservative wood can not be recycled, which wastes wood resources. Jinan antiseptic wood teaches you how to distinguish the quality of antiseptic wood.
1、看毒效
1. See poison effect
木材防腐剂的效力主要是由其对有害生物的毒性决定的,对危害木材的生物毒性越大,其防腐效果就越强。一般情况下,木材还要加入其他的剂,一是起防腐作用,而且可以增强木材的刚度,强度,耐用度。
The effectiveness of wood preservative is mainly determined by its toxicity to harmful organisms. The greater the biological toxicity to wood, the stronger the preservative effect. In general, other agents should be added to the wood. First, it can prevent corrosion and enhance the rigidity, strength and durability of the wood.
2、看持久性与稳定性好坏
2. Look at durability and stability
木材防腐剂应具有较为稳定的化学性质,它在注入木材后,不易挥发,不易流失,持久地保持应有的毒性。鉴定方法为长久不褪色的稳定性越好。
Wood preservative should have stable chemical properties. It is not easy to volatilize and lose after being injected into wood. It can keep its toxicity for a long time. The stability of the method is better.
3、看渗透力强弱
3. See the strength of permeability
木材防腐剂必须容易渗透入木材内部,并且有一定的投入深度。辨别的时候可以将防腐木从中间切开,查看渗透情况。
Wood preservatives must be easy to penetrate into wood and have a certain depth of input. When distinguishing, the antiseptic wood can be cut from the middle to check the penetration.
4、看安全性高低
4. Look at the level of security

木材防腐剂对危害木材的各种菌虫要有较高毒性,但同时它应对人畜是低度或无毒的,对环境不会造成污染或破坏。随着人们对环境与可持续发展的关心,高效环保的复配木材防腐剂受到应有的重视。如上海沛迪所采用的ACQ环保防腐剂。
Wood preservative has high toxicity to all kinds of bacteria and insects that harm wood, but it is low or non-toxic to human and livestock, and will not cause pollution or damage to the environment. With people's concern for environment and sustainable development, efficient and environmentally friendly wood preservatives have been given due attention. Such as ACQ environmental protection preservative used by Shanghai Peidi.
5、腐蚀性
5. Corrosiveness
防腐剂要对各种金属的腐蚀性小,偏于中性的比较理想。
Preservatives should be less corrosive to all kinds of metals and more neutral.
6、对木材的危害性损害
6. Harmful damage to wood
木材经防腐处理后,对木材的力学强度、良好的纹理和悦人的色泽以不影响其使用度为宜。尽量选择没有开裂的为宜。
After preservative treatment, the mechanical strength, good texture and pleasant color of wood should not affect its use. Try to choose the one without cracking.
防腐木材适于各种户外结构,包括围栏、柱子、甲板、操场、码头等。尽管尚无证据表明在上述用途中,防腐木材有副作用,但仍建议不要将之用于:
Anticorrosive wood is suitable for all kinds of outdoor structures, including fences, columns, decks, playgrounds, wharves, etc. Although there is no evidence that preservative wood has side effects in the above applications, it is recommended not to use it in:
1、会与食物、动物饲料或者饮用水(人畜用)直接接触之处,比如切肉板、柜台面、蜂箱等。
1. Places that will be in direct contact with food, animal feed or drinking water (for people and animals), such as meat cutting board, counter top, beehive, etc.
2、防腐剂中的化学物可能进入食物链之处,比如存放食品或者动物饲料的储藏箱、地窖、水槽、覆盖物等。
2. Chemicals in preservatives may enter the food chain, such as storage bins, cellars, sinks, coverings, etc. for food or animal feed.
3、防腐剂中的化学物质可能接触到公共饮用水系统(比如水井或者蓄水池盖)之处,但偶尔接触之处,比如码头和桥梁,可以使用防腐木材。
3. Chemicals in preservatives may come into contact with public drinking water systems, such as wells or reservoir covers, but occasionally, such as docks and bridges, preservative wood can be used.
4、不建议将防腐木材用于家畜的草垫、干草或者可能被燃烧的产品如木质煤球以及木炭等。
4. It is not recommended to use preservative wood for straw mats, hay or products that may be burned, such as wooden coal balls and charcoal.
此外,一般应避免在室内条件下使用防腐木材,比如室内墙板、室内地板等都不应该用防腐木材制造。但是如果室内结构存在潮湿的可能,并且这些部件的更换非常的困难,则可以使用防腐木材,如地基、地下室、底层托梁以及地板下结构。
In addition, anticorrosive wood should not be used in indoor conditions, such as indoor wall panels, indoor floors, etc. However, if the indoor structure is likely to be wet and the replacement of these components is very difficult, anticorrosive wood can be used, such as foundation, basement, bottom joist and under floor structure.
