How to know whether the preservative wood purchased is environmentally friendly? The so-called outsider watching the fun, as an outsider, consumers can only prove through the inspection certificate.

防腐木是將普通木材經過人工添加化學防腐劑之后，使其具有防腐蝕、防潮、防真菌、防蟲蟻、防霉變以及防水等特性。

Preservative wood is a kind of common wood which is artificially added with chemical preservatives, which makes it have the characteristics of anti-corrosion, moisture-proof, fungi, insects, ants, mildew and water-proof.

木材防腐劑的使用要針對合適的對象，在適當的時機進行處理，選用有效的防腐劑產品，使用恰當的濃度，采用恰當的處理方法，使木材達到正確的藥劑保持量，防腐處理木制品的使用環境是正確的。

The use of wood preservatives should aim at the right object, treat at the right time, select the effective preservative products, use the appropriate concentration, adopt the appropriate treatment methods, so that the wood can reach the correct pesticide retention, and the use environment of preservative treatment of wood products is correct.

目前防腐木加工主要有兩種防腐處理技術，一是CCA防腐處理，CCA，其主要化學成分為鉻化砷酸銅，由于CCA中含有微量的砷元素及重金屬鉻，近年來人們從心理上開始擔心其對健康的危害，美國及歐盟在本世紀初已停止使用CCA;處理過的木材，在我國用CCA防腐藥劑處理木材防腐還是占主導地位。

At present, there are two kinds of antiseptic treatment technology in antiseptic wood processing. One is CCA antiseptic treatment, CCA. Its main chemical component is chromized copper arsenate. Because CCA contains trace arsenic element and heavy metal chromium, people have been worried about its harm to health in recent years. The United States and European Union have stopped using CCA at the beginning of this century; For the treated wood, CCA preservative is still dominant in China.

ACQ是季銨銅的簡稱，它主要是由氧化銅和季胺鹽組成，它不含砷和鉻，是一種對人畜低毒的環保型的木材防腐劑。對環境無不良影響，這種新型的環保防腐劑，不會對人畜魚及植物造成危害，同時又具備良好的防腐性能。這種處理方法被認為是CCA的有效替代品。隨著相關技術的不斷改進，從長遠看ACQ將有可能成為未來防腐木材處理的主要方法之一。

ACQ is the abbreviation of quaternary ammonium copper. It is mainly composed of copper oxide and quaternary ammonium salt. It does not contain arsenic and chromium. It is an environmental friendly wood preservative with low toxicity to human and livestock. This new type of environmental protection preservative will not cause harm to human, livestock, fish and plants, but also has good anti-corrosion performance. This treatment is considered to be an effective alternative to CCA. With the continuous improvement of related technologies, ACQ will probably become one of the main methods of preservative wood treatment in the long run.
