Shanghai Dadong Wood Technology Co., Ltd. tells you: Wood preservatives Background source?
Wood is a kind of natural organic material, which has obvious biological characteristics. It is easy to be invaded by bacteria, insects, marine borers and so on. Before using, according to the different application environment, choose the appropriate preservative, carry on the appropriate treatment, can effectively delay the wood decay. With the improvement of people's living standards, the demand for wood is also increasing. The forest resources that can be harvested and used in our country are very limited, so it is unrealistic to expect to import timber with a large amount of foreign exchange. Based on domestic, making full use of existing resources and taking the road of sustainable development is the only way for the development of China's wood industry. It is one of the important ways to save wood and protect forest resources by antiseptic treatment of wood and prolonging the service life of wood products. In our country, there are few wood after antiseptic treatment, and most of them are traditional ones which are harmful to human and environment Wood preservation Agent. Therefore, it is necessary to understand the development of wood preservatives and develop new wood preservatives.
The most common way to prevent wood decay is to use chemical preservatives. At present, water-soluble preservatives are used most, accounting for about 3 / 4 of the total amount of preservatives used . As the arsenic and hexavalent chromium contained in CCA are highly carcinogenic to human storage and cause great environmental pollution, they are gradually replaced by ACQ.
The advantages of ACQ are as follows:
1) It has good anti mildew, anti-corrosion and anti insect performance;
2) It has good permeability to wood and can be used to deal with large size and difficult wood products;
3) It has a long-term effect;
4) It has low toxicity and does not contain harmful substances such as arsenic, chromium and phenol.
ACQ has been widely used in the United States, Japan and China.
Due to the narrow range of single preservative against wood rot fungi and insects, two or more preservatives are usually mixed in a certain proportion, which can not only overcome the shortcomings of single preservative, but also produce some new characteristics. Nowadays, composite preservatives have been widely used in the world and achieved good results.
Due to the shortcomings of traditional preservatives, people are forced to study and look for new preservatives which are harmless to human beings and animals, pollution-free to the environment and toxic to microorganisms only. There are many preservatives that meet the above requirements. Nowadays, more and more researches have been carried out including ammonia soluble copper alkylamine (ACQ), boride, copper DIMETHYLDITHIOCARBAMATE (CDDC), oil soluble chlorothalonil (CTL) and organic iodide (IPBC).
