Antiseptic wood is usually used for balconies or courtyards and gardens at home. I believe we don't know about antisepsis. The treatment of antiseptic wood is to put the wood in a high-pressure closed space, and then put the antiseptic into the wood, so that the wood can better penetrate into the deep cells of the wood in the high-pressure environment. Preservatives mainly include CCA, ACQ and cab. The main component of CCA is copper arsenic, the main component of ACQ is ammonia soluble alkylamine copper, and the main component of cab is copper file.
At present, ACQ is more recognized by the market
1. Vacuum high pressure impregnation process is the key step of anti-corrosion treatment. Firstly, the physical process of injecting preservative into wood is completed, and some active components of preservative are fused with wood. Is it better to use dry material or wet material?
The answer is that the dry material is better, because the log itself is only mining water containing a certain amount of water, which needs advanced drying treatment, otherwise the water of the original wood will affect the treatment of anti-corrosion effect, making it difficult for the drug to penetrate into the wood of deep cells or dilute the drug. Whether or not the natural drying is still placed in the constant temperature drying room for drying, the standard anticorrosive wood should be treated first before treatment. The standard drying should be carried out under the condition of high temperature and humidity above 80 ° for 19 hours, so as to make the oil in the wood evaporate and overflow along with the water content of the wood, so as to achieve the basic purpose of degreasing. Dry materials are used for anticorrosion treatment to ensure that all the indexes meet the national anticorrosive wood quality standards.
In addition to the causes of humidity, the use of dry materials for corrosion treatment has the following two advantages:
1. It can reduce the risk of pine oil phenomenon. There is no drying, degreasing and antiseptic wood processing. Pine oil phenomenon is easy to occur in the process of use. It occurs in summer. This situation can make the wood surface pale, and then affect the appearance. And the overflow port will be sticky. The overflow of pine oil will corrode the wood bond by the edible insect organic compound bacteria, and then lead to the acceleration of wood decadence.
2. Reduce the cracking and deformation of wood, because the deformation and cracking of wood are mainly due to the anisotropy of wood itself and the characteristics of dry shrinkage and wet expansion, so the water content in the treatment of wood and the unified water content in the use environment are equal, in order to ensure that their own wood water will not be transmitted.
