Qianshan Wood Industry: Common sense of panelboard for decoration panels
Blockboard is a kind of board commonly used in the decoration process. It is commonly known as: large core board. Many people think that they are two kinds of boards, which is actually a kind of board.
Blockboard is a plywood with solid wood core. It has longitudinal bending resistance, poor compressive strength and high lateral bending resistance. Most of the market is solid, glued, double-sided sanding five-layer joinery. Board, which is the most common decorative sheet in the current decorative market.
 
If we want to hang the ceiling in our house, the wall needs some woodwork, and the blockboard plays a huge role. Of course, in our cabinets and wardrobes, there are also a lot of blockboards. The overall weight of the blockboard is very heavy and heavier than the other plates.
Blockboard advantages:
It has good nail holding power, high strength, very hard, and very sound-absorbing, heat-insulating characteristics, water content is very low, only about 10% , very hard, so be careful when taking this kind of board, do not touch people .
But the blockboard processing is relatively simple, mainly used in cabinets, wardrobes, and other uses, doors and windows, partitions, heating covers, etc., because the interior of the blockboard is solid wood, so the equipment requirements are not particularly high during processing. Easy to process, which allows many processing plants to process blockboard.
The shortcoming is that urea-formaldehyde glue is used in the manufacturing process. This glue contains a certain amount of formaldehyde. This is the reason why this blockboard has a taste. Some manufacturers have the phenomenon of cutting corners. When splicing the core, the gap is compared. Big, if nails are nailed in the gap, the nail holding power is greatly reduced. In addition, the blockboard is longitudinally spliced, so the vertical bending resistance is relatively poor, and the long-term stress will cause the lateral deformation of the sheet and the appearance is lowered. Of course, these shortcomings use regular plate manufacturers, according to national standards, the impact is not large, so it is recommended to choose the big brand blockboard.
