In the decoration, the usage of large core boards is quite large, and about 3 million of the projects generally require 28 or so. The quality of Daxin board directly affects the quality of decoration and the quality of indoor air quality. Therefore, when you purchase a large core board, you must make a good pass. Differences in the quality of the big core board can be started from the following aspects:

1, the quality of the grinding process determines the level: the machine to fight the big core board as an example, the quality of the big core board at least two times after grinding, that is, the core of the big core board polished once, after the skin and then double-sided sanding Polished. Some plates are only polished after being well-surfaced, but the unsmoothed plate cores will be rough and uneven, which will affect the bond strength of the surface layer and cause bulging and affect the use.
2. It is better to use a single wood species for core board cores: the core material should be made of poplar and other single wood species. If different wood corners are used as cores, the physical properties of various wood fibers are not the same, and the reactions from cold, hot and humid are not the same. Such a large core board is easily deformed.
3. Distinguish between hand and machine puzzles: The hand puzzles are not as tight as the machine puzzles. The flatness and thickness will have a certain error. The quality of the core wood strips of the hand-made panels is poor, the gap is large, and the used adhesive is Poorer, the market price of good hand-made puzzles will be about 70-80 yuan, and it will be similar to the medium and low-end price of machine-made puzzles. The thickness of a good machine core board should be 1.7-1.75 centimeters, while the quality of large board thickness is 1.5-1.6 centimeters.
4, eye, ears, nose smell: a big core board to see Shun Shun yo, hand touch its flatness is good, double-sided sanding feel good. Raise the corner of the big core board by hand, measure the amount of helium, and listen to the sound inside the board. If there is buzzing, it means that the slat has poor adhesion, and if the weigh board is too heavy, it is not a good thing. This large core board core may be a kind of miscellaneous wood, and such a large core board is not easy to eat nails, and is easily deformed. When the big core board was sawn at the scene, it basically did not smell the pungent smell of formaldehyde. According to the recent one-month experiment, I feel that the Deli brand Daixin board is of good quality.
