[ Chinese wardrobe network ] When consumers buy plates, they often encounter a lot of confusion: in the face of many brands, how to choose the plate, how to identify its quality, whether the purchased plates meet environmental standards, etc. The answer to this question is as follows.
Blockboard, commonly known as the large core board. The large core board is made up of two sheets of veneers bonded together in the middle. Can be used for furniture and wooden doors and door covers, heating covers, curtain boxes, etc. The characteristics of the large core board: the large core board has good clamping force, high strength, strong quality, sound absorption, heat insulation, etc., and the water content is not high, between 10% and 13%, the processing is simple and the most widely used. The large core board is more stable than the solid wood board, but it is afraid of moisture. It should be avoided in the kitchen during construction.
How to identify the quality of the large core board:
When selecting the wood inside, it should not be too broken, and the large core board with a gap of about 3mm between the woods is suitable.
Look at the weight, look at the price. In fact, the heavier the core board, the worse the quality. Because the weight is higher, the more the board is used, the more wood is used. This large core board made of miscellaneous wood is not nailed at all, so it cannot be used. In addition, the price of a very low-core large core board will certainly be very poor. It is not a big gap, it is the use of unqualified wood.
How to choose a high quality core board:
A look at whether it is a regular manufacturer's product. To check the manufacturer's trademark, production address, anti-counterfeiting mark, etc. Second, look at the formaldehyde emission in the product test report is less than or equal to 1.5 mg per liter. The formaldehyde emission of E0 grade plate is less than or equal to 0.5 mg per liter. Generally, there are test reports produced by regular manufacturers. The detection value of formaldehyde should be as low as possible.
How to use large core boards reasonably to reduce formaldehyde pollution:
Generally, the maximum core board should not exceed 30 sheets in the room of about 100 square meters. At the same time, other indoor decoration should be considered. If used too much, the formaldehyde in the indoor environment will exceed the standard. In particular, do not use a large core board as a lining under the floor to avoid serious formaldehyde in the indoor air.
