1.Temperature:fir pileThe main influencing factor of drying speed is temperature. Temperature rise isfir pileThe water pressure in the water will increase, and the viscosity of liquid free water will also decrease, which will help promotefir pileThe flow and diffusion of moisture in the medium will increase the wetting capacity 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 be reduced.

2. Humidity: Humidity will also affectfir pileDrying. When the temperature and air flow speed are the same, the higher the relative humidity, the greater the partial pressure of water vapor in the medium.fir pileThe moisture on the surface is not easy to evaporate, so the drying speed will naturally slow down.

3. Air circulation speed: high air flow will destroyfir pileThe saturated steam boundary layer on the surface improves the heat transfer and mass transfer conditions between the medium and the fir pile, and accelerates the drying speed. For wood that is difficult to dry or when the moisture content of the fir pile is relatively low, the moisture inside the fir pile Movement will determine the speed of drying. At this time, increasing the flow rate to speed up the evaporation of surface water has no effect, and may also have a counterproductive effect. Therefore, this method is not recommended for difficult-to-dry wood. How should fir piles be preserved? The following Yang's Wood Industry will introduce to you the characteristics of wood preservatives.

1. High toxic effect: averagefir pilePreservatives are toxic, and the greater the toxicity, the better the anti-corrosion effect. Generally, when adding preservatives, other chemical reagents will be added, which can better enhance the stiffness, strength, and durability of the wood.

2. Good durability and stability:fir pileThe preservative must have stable chemical properties. After being injected into the fir pile, it will not be easy to exert and lose, and it can maintain its proper toxicity for a long time.

3. Strong penetration:fir pileThe preservative must easily penetrate into the interior of the fir pile.

4. Low corrosiveness:fir pilePreservatives 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.
