Disasters are merciless, and we always feel regret and sorrow after they occur. Therefore, fire prevention must start from the source. Using fire-retardant boards in renovations can slow the spread of fire, buying more time for rescue. This is especially important in densely populated places such as shopping malls, hospitals, office buildings, and schools, where firefighting and evacuation are difficult.
So what exactly is flame-retardant board, and does it really not burn?
In the building materials market, fire-retardant boards have many names, such as fire-retardant plywood, flame-retardant plywood, and fire-retardant board. This type of board is made by rotary cutting logs into wood chips or planing timber into small blocks, treating the wood chips with fire retardants, and then gluing them together with adhesives. It is typically made with an odd number of wood chips, with the fiber directions of adjacent layers perpendicular to each other. This process largely overcomes the defects of wood, greatly improving its physical and mechanical properties. At the same time, flame-retardant plywood also overcomes the flammability of ordinary plywood, effectively improving its fire-retardant performance.
Therefore, flame-retardant boards are not non-flammable, but they prevent the fire from spreading, making them more difficult to burn.
So what kind of flame-retardant board is good?
The quality of a flame-retardant board can be judged from two dimensions: flame retardancy and environmental protection. On the one hand, the flame retardancy rating should be high enough, and on the other hand, it should meet the national environmental protection standards.
Flame-retardant OSB board, B1 flame-retardant grade, and formaldehyde-free environmental protection level, is a brand-new upgraded high-quality flame-retardant board.
Advantages of flame-retardant OSB boards
B1 flame retardant rating
The new generation of flame-retardant OSB board is made from imported pine wood sliced into sheets. It changes the traditional coating/immersion process for large boards and adopts a small-piece spraying method with up to 120 three-dimensional nozzles spraying at high speed. The flame retardant penetrates into every tiny pore, perfectly achieving B1 rating, making it safer!
Formaldehyde-free and environmentally friendly
It uses MDI formaldehyde-free adhesive, and according to the industry standard "LY/T 1580-2010 Oriented Strand Board", there is no need to test for formaldehyde emission limits, making it healthy and environmentally friendly.
Safe and reliable
It has passed the testing of the National Fireproof Building Materials Quality Supervision and Inspection Center and obtained the Certificate for the Use of Flame Retardant Products and Components Labels in Public Places.
It meets the requirements of the national standard GB 8624-2012 B1 (c-s1,d0,t2) level, and the tests for individual combustion, combustibility, and smoke toxicity level are all qualified.
Good product consistency
The board has small internal density deviation and external thickness deviation, which facilitates construction and ensures construction quality.
Stable performance
Produced on a world-class automated production line, subjected to high temperature and high pressure, ensuring static bending strength and bonding strength, making it sturdy, durable, and resistant to deformation.
Good moisture resistance
It has a small coefficient of linear expansion; after 24 hours of immersion in the sample test, the expansion coefficient is ≤8.6%, indicating good moisture resistance.
The all-new, upgraded formaldehyde-free flame-retardant OSB board is truly environmentally friendly with no added formaldehyde, and every pore is flame-retardant!
