Why choose LVL sheet
Laminated LVL, or LVL for short, is a veneer made of logs as raw materials by rotary cutting or planing, then dried, coated, assembled according to the grain or most of the grain, and then laminated by hot pressing. It has the structural characteristics that solid wood sawn timber does not have: high strength, great toughness, good stability, accurate specifications, which is three times higher in strength and toughness than solid wood sawn timber. This product has the advantages of high environmental protection, waterproof, fireproof, anti-corrosion, pest prevention, and no fumigation

LVL forward plate shall be strictly controlled for the whole drying process. The manufacturer of the packaging board reminded that sharp things must be prevented from using on the surface of the packaging board to prevent damage to the phenolic resin film on the surface. If it is stored for a long time, the surface of the packaging board should be coated with a surface agent for protection.

First of all, in terms of the product characteristics of LVL directional board, it has good durability. Through comparison in the use process, the damage is less than that of the adhesive layer when the finished wood is glued; Its strength function is good, and its log shortcomings are evenly distributed in LVL, and its uniform function is better than that of finished wood.

The drying speed of LVL forward plate is also determined by surface evaporation and internal diffusion, but its surface evaporation area is large, the internal diffusion resistance is small, and the surface evaporation and internal diffusion are very intense. They can adapt to each other. Therefore, high temperature rapid drying process can be selected during veneer drying.

Generally, abnormal drying occurs because of the relationship between raw materials. Because the internal moisture content and water absorption of different tree species are also different, it is necessary to adjust according to the product specifications and tree species during processing. In addition, the state of the surrounding environment will also have a certain impact on the drying situation, if the ambient humidity is adjusted.

When transporting LVL forward plate, relevant wear measures must be taken, which is an important link to ensure the application quality. In many cases, if the materials are worn without dead angle for 360 degrees, it is due to the collision hazards between the wood blocks stacked together, because the damage is relatively serious.

In the choice process of many people, they will choose expensive people. There are many types of lvl forward plate flooring, and the quality of different types of flooring is also different. The choice must be made according to the actual situation. We hope that any product will have good robustness when it is purchased.

LVL forward plate has been used in many fields. First, it is used in furniture work. Because of its flexibility, durability and processability, it is widely used in furniture work. Then there is the wooden packaging work. The traditional wooden packaging uses solid wood materials. Due to the environmental differences among countries, the customs of various countries have made suggestions on wooden packaging materials.

The excellent creep resistance is very excellent in the natural creep test, which can reduce the changes in its own shape caused by deformation and external forces, and can persistently adhere to the appearance shape of a better LVL forward plate; The excellent appearance integrates the external image, and the physical performance of the LVL forward plate is excellent.

The production process of LVL forward plate mainly includes monotonous substrate, mold paper foam, hot pressing, etc. If the dryness of the substrate is not enough and the plate is too wet, foaming, moisture reversal and cracking will occur during use; If the glue on the mold paper is uneven and the hot pressing temperature is not enough, the mold paper and the substrate cannot be really integrated and then formed.

When selecting the LVL forward plate, the product with clear wood grain shall be selected, and the front shall be smooth, smooth, not rough, and flat without sluggish feel. The surface of LVL forward plate shall be free of defects such as damage, bruise, hard wound, scar, and degumming. Attention shall be paid to that the joint of plywood shall be tight without unevenness.

The use and storage environment of LVL forward plate should be suitable for both temperature and humidity. If the temperature is too high, the glue inside the plate will change, which will affect the stability of the plate. If the temperature is too low, the plate will crack; If the humidity of the environment is too high, the plates will become moldy, and if the humidity is too low, the plates will crack.
