1.  The reason for opening the glue?
Answer: Laminates (including veneer, wood board, and multi-layer boards) can be glued due to the following reasons: (1) Poor glue quality    If it is a low-end product, the glue used in it has low viscosity, which will lead to glue opening and delamination; Due to the lack of the curing agent of formaldehyde, the environmentally friendly glue, if the other ingredients are not good or the processing technology is not good, the bonding force will be reduced. (2) Poor wood material    If the wood contains water

If the rate is more than 14%, there will be the possibility of opening the glue. The higher the moisture content, the greater the degree of opening. (3) The middle board of some multilayer boards is made of fragments, and the glue will be opened due to uneven height. Even if the putty is scraped, the glue will open.
2. Why is it easier to open the glue in winter?
Answer: Due to the low temperature in winter, it is difficult to dry the wood, which will increase the moisture content. At the same time, since the regaining speed of the adhesive layer in winter is much faster than in summer, the curing speed will be much slower, which will reduce the adhesiveness. , So the laminate is easier to open in winter.
3.  Wood board and panel are easy to rise?
Answer: The processing technology of wood board and panel are similar, both belong to the plywood category. Since the production of plywood is a large-scale non-standard production, it is more likely to cause quality problems, especially the opening of the glue. It’s just that standard manufacturers have fewer quality problems, and non-standard manufacturers have more problems, so you should choose products from large manufacturers to avoid quality problems. But this type of product

Will be in a higher grade, so the price is higher.
4.  The difference between the whole puzzle and the hand puzzle? (How to recognize the whole puzzle and the hand puzzle)
Answer: The whole board is the machine-made board, which is to use the automatic ballasting machine to put the wooden core strips into a whole core board; the hand-made board is to manually arrange the wooden core strips together, including pure hand-made, two-piece, and three-piece board. In the market, three and two puzzles are often called manual puzzles because they mislead customers. The characteristics of the whole panel are: ①The wooden core strips are of equal width and thickness, ②The wooden core strips are glued together, and the appearance quality

It won’t be bad. High-grade woodworking boards are all integrated boards. Hand-made features: ①The wooden core strips are not of equal width, ②There is no glue or not completely glued between the wooden core strips, ③The false heads with equal-width wooden core strips are made by hand, and the false heads are more obvious. There is a seam in the center of the short side of the two panels; each of the three panels has a seam at the third point of the short side. ④Most of the hand panels use hydrogen peroxide and ammonia

Add talcum powder to dye the edge, the surrounding is whiter, not the natural color of the wood, so the wood board that has been dyed must be hand-made.
5. Is the quality of the wedge-shaped wood board better? If not, why is the price more expensive?
Answer: The use time of wedge core strips is not long because some manufacturers believe that this will strengthen the bonding force of the core strips in the core board and make it difficult to disperse; some manufacturers do not use the wedge core strips because they do not have a splicing machine. Put all hands together into a whole piece. Because the material requirements of the wedge core strip are higher than that of the flat core strip, and more wood is used at the same time, its cost is higher than that of the flat-ended splint, so the price

The bit is slightly higher.

6. Can I paint directly on the wood board?
Answer: Under normal circumstances, the surface of the wood board can be painted directly, but for the sake of safety, it is best to tell the customer to stick a good three-layer board on the surface.

7. What does the symmetry of plywood do?
Answer: The principle of symmetry is the most basic principle for the production and use of plywood. This is to avoid deformation, warping, and cracking of the plywood, because the wood has large changes and cracks along the grain direction.

8.  What kind of wood is the surface of plywood?
Answer: The surface of multi-layer board and wood board often includes: Okoume (mahogany), big white wood, white rue, cologne (clone wood), eucalyptus, etc. The most common is the pink Okoume. The surface of the veneer is made of different wood due to different decorative effects.

9. Is the surface of the veneer and plywood the same wood?
Answer: Under normal circumstances, the veneer is different from the multi-layer board and wood board. But the more popular red walnut on the market is actually Okoume. It’s just that the surface of the veneer is sliced, and the surface of the multi-layer board and wood board is peeled.
10.  What kind of wood is there in the base layer of the veneer? Which is best?
Answer: The base layer of the veneer often has eucalyptus, miscellaneous wood, poplar and so on. This refers to the material of the middle core board of the base layer. The base plate of eucalyptus and miscellaneous wood is hard; the rate of deformation of miscellaneous wood is larger; while poplar is more expansive and easy to absorb moisture, so it is prone to mildew; therefore, the substrate of eucalyptus is the best.
