How to distinguish the quality of flame retardant board ? In our lives, flame retardant boards are still widely used, but 90% of the flame retardant boards are limited to commercial real estate uses. Now, many high-end communities, villas, and high-rise buildings also use flame retardant plywood. The widespread application of flame retardant boards has made many people have some doubts while purchasing, just because they don’t know how to distinguish the quality of flame retardant boards. Quanwen Science and Technology has summarized several methods for identifying flame retardant boards. Let’s learn together.

1. How to identify flame retardant board

flame retardant board (also known as flame retardant plywood). Flame retardant plywood is a three-layer or multi-layer plywood made of logs rotary cut into wood slices or cut into small wooden squares, and then glued with adhesive. It is usually made of odd layers of wood slices, and the fiber directions of adjacent layers of wood slices are glued perpendicularly with each other.

Flame-retardant material board produced with wood as the main raw material can generally overcome the defects of wood in the production process of reasonable structure and fine processing, thereby greatly improving and improving the physical and mechanical properties of wood. In addition, it also overcomes the shortcomings of flammable ordinary plywood and effectively improves the flame retardant performance of plywood. The Millennium Boat Flame Retardant Board has five major characteristics: flame retardant, smoke resistance, corrosion resistance, insect resistance and stability, and can be said to be very practical. It maintains the excellent physical performance, processing performance and decoration functions of traditional artificial boards, and is widely used in public construction and decoration projects such as hotels, hotels, conference centers, exhibition centers, sports centers, libraries, transportation and transportation centers, leisure and entertainment venues, shopping malls, medical institutions, office buildings, building decoration projects of high-end residential buildings, and manufacturing projects of high-end furniture.

2. How to determine whether the flame retardant board is good or bad?

Suggestions—touch, burn, three pinch, four bubbles, and five smells.

1. Once you touch it, you will touch with your hands whether the surface of the board is smooth.

2. Secondly, use a blade to cut a small strip, burn with a lighter, observe the extinguishing time, see if there is any dark fire, and compare it with ordinary boards.

3. Three pinching means pinching the core of the board with your nails, it will feel hard or soft; then pinching the nails upwards near the board surface to observe whether the surface layer is peeled off easily.

4. Four bubbles means soaking a small piece of sample in cold water for 24 hours to observe how much thickness increases. This item is the most critical

5. Five smells are just a few flame retardant boards stacked together and sticking them to the edge of the board to smell whether it has a pungent smell. If it is said that the formaldehyde emission is high and the environmental protection performance is poor, it is not recommended to buy it.
