As a subtropical tree species, fir loves light and is not tolerant of severe cold and heat and humidity. It is widely used in various places. What are its influencing factors? How to preserve fir piles?

1. Temperature: The main factor affecting the drying speed of fir piles is temperature. When the temperature increases, the water pressure in the fir piles will increase, and the viscosity of liquid free water will also decrease, which helps to promote the flow of water in the fir piles. And diffusion, improve the melting and wetting ability of the copper wire drying medium, and accelerate the evaporation rate of water on the surface of the fir pile. However, the temperature should not be too high. If it is too high, the fir pile will crack and deform, and the mechanical strength will also decrease.

2. Humidity: Humidity will also affect the drying of fir wood piles. Under the same temperature and air flow speed, the higher the relative humidity, the greater the partial pressure of water vapor in the medium. The moisture on the surface of the fir wood piles will not evaporate easily, and the drying speed will naturally change. slow.

3. Air circulation speed: High air flow will destroy the saturated steam boundary layer on the surface of the fir pile, thereby improving the heat and mass transfer conditions between the medium and the fir pile, and speeding up the drying speed.

In addition, how to prevent fir wood piles? The editor below will introduce the characteristics of wood antisepsis.

1. High toxicity: Generally speaking, fir wood pile preservatives are toxic. The greater the toxicity, the better the antiseptic effect. Generally, other chemical reagents are added when adding preservatives, which can better enhance the rigidity, strength and durability of the wood. sex.

2. Good persistence and stability: The preservative for fir wood piles should have stable chemical properties. It is not easy to develop and lose after injection into fir wood piles, and can maintain its due toxicity for a long time.

3. Strong penetration: The preservative for fir piles must be able to easily penetrate into the interior of the fir piles.

4. Low corrosivity: fir wood pile preservatives cannot corrode wood, so they are less corrosive.

5. Although it is a reagent to prevent fir piles from corroding, it still has certain harm to fir piles.
