The insecticidal treatment of paulownia lumber may be a bit confusing at first glance. I was also very confused at the time, and the master explained it to me.
If the paulownia log board has been processed, the moisture content of all parts is not much different, at about three milliseconds, there is no need for insecticide treatment, but if it is not within this range, insecticide treatment is required.
There are two main methods of insecticidal treatment:
1. Fumigation and insecticide:
The fumigation of paulownia logs is the same as fumigation of other materials. It relies on the volatilization of the medicine to kill the insects by breathing. This method is most commonly used and most convenient.
2. Microwave high temperature insecticide
The paulownia wood is sterilized by microwave and high temperature. Using advanced microwave technology-microwave energy penetrates into the inside of the paulownia log board, so that the outside and the inside of the paulownia log generate heat at the same time, without external heat and internal cooling, the surface color of the product does not change when the product is microwaved, and the speed is fast and efficient; After microwave treatment. Achieve no insects and ensure good quality for a long time. The equipment has a high degree of automation and simple operation. Finally, the performance of paulownia board is balanced. It is guaranteed that there will be no insects within 3 years!
The above is the explanation of the insecticidal treatment of paulownia board.
