So how do you distinguish the quality of packaging?
First of all, it can be judged visually with the intuitive feeling of touch. You can feel whether the package on both sides of the wood is flat and whether there is uneven foaming. If you do not have a smooth and rough feeling, you must begin to doubt whether the packaging is of poor quality.
Look at the side of the edge, the main problem of the unqualified side seal is the poor adhesion of the edge strip and the side edge, there are two main reasons: First, because the particle board and the density board are scrap glue, so there is If the edge is not smooth and rough, if the amount of glue used in the edge strip is insufficient, the edge strip can easily come off. Second, the quality of glue used in the edge banding is not good, and it is easy to fail. The quality of the glue in the past year or two may be very good in the past year, but as the time increases, oxidation and moisture in the air cause a series of causes, and then it will fall off. , And many businesses will use "usually caused by improper use of customers" as an excuse for consumers to suffer from a loss.
The fractures of the solid wood eco-board and the solid wood multi-layer board are flatter than those of the particle board and the density board, so the glue effect under certain conditions is better than that of the particle board and the density board.
Specifically, what should be done? The best option is to let the merchant provide a sample of furniture materials to test.
Common ways can have:
1. Look hard and see if the package material will loosen. If it is loose, then the package material must not be firmly bonded or even have gaps in the adhesive surface. It is impossible to effectively prevent the volatilization of formaldehyde in the inner material.
2. Use a sharp object to cut the package surface to see the thickness of the package material. Generally, the thickness is 1-1.5mm, which can be considered as the target, which can effectively block the volatilization of formaldehyde in the material inside;
3. Peel off the edge banding (mainly based on PVC edge banding, so the stripping work is also more convenient. Look at the flatness of the wood section and look at the glued area. If only a small part of the area is covered with glue, If you want to know that the effect is necessarily bad, of course, you can also take the opportunity to smell whether there is a pungent taste to simply determine the strength of the adhesive used.
4. Use a lighter to point the packaging material. Qualified packaging material should have a certain fire performance. If the packaging material is easily deformed or even ignited after ignition, it is definitely unqualified material. Purchase of such a plate will become a family. The danger of a fire.
There is no absolute difference between materials, especially in terms of physical properties, such as sound insulation performance, strength, degree of compression, etc. Even the same kind of material will have many differences. When you choose, you can learn more about the performance parameters of the materials and ask the merchants to issue relevant reports. They always help themselves to make choices and evade some of the options that will be regretted after purchase.
