At present, the plates of panel furniture are mostly made of particleboard and medium density board. Since both kinds of boards are made of wood and pulverized and then mixed with adhesive, the amount of glue determines the chemical composition and determines the environmental protection level. High and low. Consumers are very concerned about which boards are more environmentally friendly. When introducing a product, a furniture salesperson said: 'Our plates are all solid wood particleboards in the northeast. You see, how big is the granules, and the glue used is less, can it be the same as the MDF glued with glue? More environmentally friendly than their MDF! 'Is this really the case? Experts from the China Furniture Association told the reporter: 'Qualified, that is, the environmental protection of MDF and particleboard that meet the national standards is the same. There is no more environmentally friendly statement. Usually, the so-called MDF refers to MDF, also called MDF. It is a kind of artificial board which is made of wood or plant fiber by mechanical separation and chemical treatment, mixed with adhesive and waterproofing agent, and then paved, formed and high temperature and high pressure. The density is relatively uniform and the mechanical properties are close to wood. An artificial plate that is more popular internationally. The difference between particleboard and MDF is that the density of particleboard is close to that of medium density fiberboard, but because the particleboard is pressed by the binder material, the density is not uniform, the middle is low, and the two ends are high, so the nail holding power is low. For medium density fiberboard. Moreover, the surface of the MDF is relatively fine, and the flatness is higher than that of the particle board. However, particleboard is better in terms of moisture absorption and moisture resistance than medium density board, and the price is relatively low. Therefore, it can be said that qualified MDF and particleboard are only functionally different, and no one is more environmentally friendly. The raw material of the particleboard is not completely pulverized into fibers, but is pulverized into granules, which is generally referred to as shavings, and then added by gluing. The MDF is completely pulverized into fibrous and then added to the rubber. Made up. 150mm (6 Inch) Depressed Center Grinding Disc B&H TOOLS CO., LTD. , https://www.bandhtools.com
