[ Chinese wardrobe network ] In the custom furniture industry, the application of the plate has long been overwhelming. The consumers often see in the market that the brand is good for MDF, the brand is said to be particleboard. Well, another brand said that the straw board is better. Xiaobian made a simple comparison of the national standards of the three kinds of plates. Particleboard definition A board made of wood scrap (wood shavings, sawdust or similar materials) or non-wood plant scraps (flax, bagasse, wheat straw, straw or similar) hot pressed with an adhesive. MDF definition Using lignocellulosic or other plant fibers as raw materials, preparing by fiber, applying synthetic resin, and pressing into a plate having a thickness of not less than 1.5 mm and a nominal density ranging from 0.65 g/m3 to 0.80 g/m3 under heat and pressure. . Straw board definition A board made of wheat (rice) straw as a raw material, an isocyanate resin as an adhesive, and a process of pulverization, drying, sorting, sizing, molding, pre-pressing, hot pressing, cooling, and the like. Reference Standard: Particleboard standard GB/T 4897.1-2003 MDF standard GB/T11718-2009 Straw board standard GBT21723-2008 Related value description The following are the values ​​corresponding to the thickness of the furniture used for 13-22mm. For other controversial values, please check the relevant standards. The water content can be simply understood as the ratio of the moisture content of the board. The smaller the value, the better. The above table shows that the medium density board does not have this parameter, and the particle board has a smaller water content upper limit than the straw board. This project won the competition for particleboard. Density refers to the unit density of the plate. In theory, the larger the value, the better. Because the corresponding density is applied to different environments, for example, the density of the MDF is only 0.65, which can be used for exhibition hall construction and temporary use, and reaches 0.8 or The above can be used for load-bearing applications or outdoor, so this project is temporarily flattened. The static bending strength can be understood as the bending variable performance. The above table shows that the national standard quality of the medium density board is higher than that of the other two sheets, so the medium density board wins at this point. Elastic modulus is a physics metric that is very important for materials. The larger the value, the better. The current national standard does not find this parameter for Class A particleboard products used in furniture production. The MDF wins in the two existing indicators. The internal bond strength refers to the density strength in the sheet. The larger the value, the better. Therefore, the MDF wins in the project. The surface bond strength can be understood as the surface adhesion strength. The larger the value, the better. In this project, the MDF and particleboard win. Water swelling can literally be understood as the probability of the expanded absorbent sheet, this value is as small as possible, thus winning the item straw board. The holding screw force, that is, the holding force , is closely related to the firmness of the plate when applying the screw. Therefore, it is very important to have a parameter value. However, due to the different application environments of the MDF, the value is stated in the standard setting. It can be prepared by both the supplier and the buyer. In the existing values ​​of the project, the particle board wins. From the above comparison, the national standard requirements for straw boards are the lowest. In comparison of multiple parameters, only the water absorption expansion rate exceeds the other two comparison sheets, while the particle board and MDF requirements are relatively high, according to the previous investigation report. View China's custom furniture industry sheet application survey report] to see the particle board use market is larger than the MDF and the straw brand is more representative of the brand of the fragrant board only 9% of the final. Taking the 18mm thickness E1 environmental protection standard (this is the highest standard in the country) as an example, from the current three types of plates on the market, there is a certain reputation of the plate brand purchase price, straw plate > MDF > particle board, and glue The comparison is the particle board <straw board <MD board, from the scope of application is the following table (only for most brands as an example): Therefore, it can be basically considered that the particle board is the choice of most brands under the market economy of the wardrobe industry. In the wardrobe (custom furniture) industry, the MDF and the particle board are the main choices, while the straw board is slightly different in the comparison of the national standard related parameter values. For the other two types of plates, it is not currently the main application material in the industry.
