First, the difference retardant MDF ordinary MDF 1, the apparent difference: Flame retardant MDF MDF belong in a functional MDF. From the exterior, the red, mainly based on the international calendar with a red dye used to dye the fibers to ordinary MDF difference. 2, physical and mechanical properties of flame retardant MDF is medium density fiber board, you must first have the physical mechanics of ordinary MDF to meet the requirements. Since the flame retardant MDF is added in the production process, the physical and mechanical properties caused some impact, especially on water absorption expansion coefficient. The use of water absorption coefficient of expansion large retardant MDF will cause delamination and unable veneer sheets, plates and even deformation, etc., eventually leading engineering quality problems. 3, functional with fire retardant MDF function, to prevent the fire stretch. Second, how to identify from flame retardant MDF MDF MDF with various common to individually as follows: 1, color color retardant MDF is dyed in red dye, so the red MDF board, not necessarily retardant MDF, this point can not be identified. 2, physical and mechanical properties due to the flame retardant added, resulting in a certain degree of influence on the swelling of the plate, so that the detector plate absorption coefficient of expansion, can initially determine retardant MDF is to meet the requirements. Swelling coefficient detection methods are as follows: Determination of thickness swelling simple: cutting the size of the approximate alternative model, first with the number after a micrometer to measure the thickness of the template of the measuring point, then add water and soak for 24 hours. Out and then measure its thickness, can be calculated before and after immersion thickness variation of the relative thickness swelling. 3, functional fire-retardant MDF functionality, that is fireproof performance. The detection method that is simple to get the fire to burn to see whether further combustion flame retardant. Flame retardant Easy Identification: A small piece is cut with a blade (diameter 2-3mm), lateral timing of burn, burn time of five seconds, from the fire, self-extinguishing within 10 seconds and no samples on Mars, you can reach C-class; the other vertical sampling is completed, the combustion time is five seconds, from the fire, self-extinguishing within five seconds samples, and no Mars, you can reach the B level. In summary, how to identify fire-retardant MDF, which is "to take water bubbles, get the fire burning!"
