As we all know, wooden furniture is divided into solid wood furniture and panel furniture according to the material composition . Among them, panel furniture refers to disassembled modular furniture with wood-based panels as the main substrate and plate as the basic structure, because of its plasticity and price. The lower advantage is loved by consumers. For consumers, the names of wood-based panels such as particleboard , fiberboard , and blockboard are familiar, with some understanding, but not accurate enough. Below, Xiaobian will arrange the four misunderstandings of furniture plates for everyone .
Misunderstanding 1: Blockboard is solid wood board
The blockboard is also called a large core board. The logs are cut into strips, spliced ​​into a core, and the outer surface material is processed. Because the main materials are solid wood, many sales people will introduce environmentally friendly plates. In fact, the large core plates are artificial boards with adhesives.
Myth 2: Trimeric hydrogen ammonia plate is medium density board
Many sales people will tell you when they introduce the products that they use a tripolyhydrogen ammonia plate. When consumers further ask what the tripolyhydrogen ammonia plate is, they are told: "The trimeric hydrogen ammonia plate is the MDF." Under the misleading of sales personnel, consumers generally believe that the trimeric hydrogen ammonia plate is a medium density board. Conversely, the medium density board is a trimeric hydrogen ammonia board. In fact, the sheet is a paper printed with color or wood grain, which is immersed in a melamine transparent resin and then heat-pressed on the surface of the substrate. After the melamine resin is cured, the veneer has good physical properties such as abrasion resistance and scratch resistance, and has certain resistance to open flame. The plates made of this material are called tripolyhydrogen ammonia plates, and the substrates are different. MDF and particleboard can be made into tripolyhydrogen ammonia plates.
Misunderstanding 3: Solid wood particle board is a "new environmentally friendly product"
Since many types of indoor pollution have been caused by panel furniture made of medium-density boards and particleboards that have not yet reached the national standard, the reputation of these two types of boards is not very good. Therefore, many sales people have given new names to these two types of boards. Name, misleading consumers. The most common name is called MDF, which is called particle board. Some sales people will add the word "solid wood" in front of them to indicate that they are "natural, environmentally friendly" products. Some sales people will say: "We use the new products developed by our company, natural solid wood particle board, absolutely environmentally friendly." When consumers carefully question the difference between solid wood particle board and solid wood, the sales staff is vague, not to admit Their true identity: "The solid wood particle board is the solid wood pellets. It is definitely different from the solid wood. The panel furniture is awkward! But, look at this price, the same environmentally friendly thing, can solid wood furniture be so cheap?" If consumption All the way down, I met seven or eight sales people to say so, can not faint!
Myth 4: Particleboard is more environmentally friendly than MDF
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, that is, its environmental protection degree. . 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. Some furniture salesmen said when introducing the product: "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? The board is more environmentally friendly!†Is this really the case? Experts from the China Furniture Association believe that “the qualified, that is, the environmental protection of the 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 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.
