[ Chinese wardrobe net ] sheet is the main component of the overall wardrobe , its quality directly determines the quality of the product. The wardrobe panels on the market mainly use wood-based panels, while the use of solid wood is rare. Wood-based panels are further divided into splints, particle boards (particle board), and fiberboard. Among them, fiberboard has high density, medium density and low density. 1, particle board (particle board): middle long wood fiber + fine wood fiber on both sides, pressed into a board. There are 18MM, 25MM, and so on. The expansion ratio, fire resistance, deformation resistance, and nail holding power are superior to the MDF. The high quality imported particle board meets the highest European E1 standard and the formaldehyde content is less than 0.9mg/100mg. The molecular structure is tight, the bending strength is high, and the moisture-proofing agent is added, and the nail holding ability is strong, and the specification is 2.44*1.22, which is 4.8 ft. 2. MDF (fiberboard): The powdered wood fiber is pressed at high temperature and the surface is flat. It is suitable for blister board, baking varnish board, etc. Because it is mostly broken into pieces, and the particle board has long wood fiber, more retains the characteristics of wood, so the MDF expansion rate is higher than the particle board and it is easy to deform. MDF is also divided into low-density boards, medium-density boards and high-density boards. Blacker merchants will use low-density boards, while high-density boards will be used for business, and moisture-proof performance is better. Many people think that particleboard is more environmentally friendly than MDF, but this is not the case. Currently, the plate of furniture on the market is mostly made of particleboard and MDF. Since both plates are made of wood and pulverized, they are made of adhesive. The amount of glue determines the amount of chemical composition, which is the degree of environmental protection. The reporter learned that most consumers are very concerned about which of the two types of plates is more environmentally friendly. As a result, many salespeople tend to mislead consumers when they market their products. In the interview, a furniture salesperson told reporters when introducing the product: "Our plates are all solid wood particleboards in the northeast. You see, how big the particles are, the glue used is less, and it can be the same as the MDF glued with glue. Is it more environmentally friendly than their MDF! "Is this really the case? The experts of the China Furniture Association told the reporter: "The qualified, that is, the environmental protection of the MDF and particleboard that meet the national standards is the same, does not exist. Which is more environmentally friendly. "The so-called MDF usually 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 raw material of the particleboard is not completely pulverized into fibers, but is pulverized into granules, which is generally called shavings, and then added with rubber. The MDF is completely made of wood raw materials. It is pulverized into a fiber and then added by a rubber. The density of the particleboard is similar to that of the medium-density fiberboard. However, since the particleboard is pressed by the shaving material and added to the adhesive, the density is uneven, the middle is low, and the two ends are high, so the holding force is lower than that of the 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.
