How to choose blockboard

The blockboard is commonly known as the large core board. It is a solid wood plate or a square plate made of rubber or non-stick solid wood strips. The two sides are covered with two or more layers of different textures of the veneered veneer (thin wood). A special plywood made by hot pressing and sanding. The main tree species of the core board are Liujing, Chinese fir, pine, poplar, etc. The main tree species in the surface layer are Oguman, Liuqi, Shanxiangguo and Huangzhixiang. The commonly used tree species in the market of Zhejiang market are Chinese fir and poplar. The Chinese fir is the best, the poplar is the second, and the common tree species in the surface are Oguman and Liujing.

The blockboard can be divided into two types according to the processing technology. One type is the hand-made board, which is to manually tile the solid wood strips together and form a fixed by sticking with the two layers of the upper and lower boards. The nail force is poor, the gap is large, it is not suitable for sawing and processing, and it can only be used in one piece; the other is the mechanism board, which is made by processing the solid wood strips together, removing the adhesive connection between the layers and the solid wood. There is also glue bonding between the strips, and the quality is better than the hand-made panels. Blockboard is the main material for home decoration and furniture production. Due to the different processing techniques and materials selected, there are still great differences in the tree species of embedded materials, the degree of processing fineness, the use of adhesives, and the selection of surface trees. Therefore, be careful when selecting blockboards:

one look

1. Look at the appearance: The appearance of the good blockboard is smooth, the board surface is smooth, no warpage, deformation, foaming, depression, and the surface color is slightly deep. Inferior boards are generally white, with special fresh trim to mask their lack of quality, and even paint all around (or other colors) with paint. Since the coating covers the texture of the material, it is easy to identify. If there is a phenomenon of filling glue and filling putty around it, it is also likely that there are gaps or voids inside.

2, look inside: If there are conditions, it is best to saw the board open to observe the surface, to see if the inner core is even and tidy, there can be no cracks. Whether the bonding is firm and there is no looseness. Whether the quality of the core strip is qualified, there must be no decay, breakage, insects, etc.

Second, ask

1. Ask the processing technology: Is it a machine piece or a hand piece?

2. Ask the tree species: The texture of the different tree species varies greatly.

3, ask for environmental performance: "national standards" require that the amount of formaldehyde released directly into the indoor blockboard must be less than or equal to 1.5 milligrams per liter. Blockboard is divided into E1 and E2 according to its formaldehyde emission, and only E1 grade blockboard can be used for home interior decoration. When purchasing, what is the environmental rating? Its superiority is the product that has obtained the certification of China's environmental labeling products.

Third, listen

1. Pick up the board and listen to whether there is a "beep" sound. If there is any, the board is not glued well.

2. Gently tap the surface with your fingers or small wooden strips. If there are holes inside, the sound will be different from other places.

Due to the asymmetry of information, for the majority of consumers, the choice of blockboard to see the brand is a shortcut, not only quality assurance, there is no worries in after-sales service.

After editing: According to the sampling results announced by the Provincial Bureau of Quality and Technical Supervision, the pass rate of blockboard is only 26.7%. At present, the unit price of blockboard on the market is between 55 yuan and 140 yuan. Generally speaking, the quality of products with low price is difficult to guarantee. Therefore, consumers should not only look at the price when purchasing, but also master some basic purchasing knowledge. Very necessary.
