Fire retardant particle board: basically use liquid flame-retardant to treat the wood particles (spraying liquid flame-retardant). Mix the flame retardant into the resin: Due to the limited amount of flame retardant added, it is usually supplemented by sizing or secondary air delivery.

Flame retardant suitable flame retardant: flame retardant is difficult to react with the methylol of urea-formaldehyde resin, such as inorganic flame retardant such as aluminum hydroxide and magnesium hydroxide, and phosphorus-nitrogen flame retardant with surface modification treatment The flame retardant is covered by the adhesive, which has little effect on the physical and chemical properties of the product. The flame retardant that can be added is limited (20-30kg/m3), and the flame retardant needs to be supplemented during sizing or secondary air delivery.

After metering, the powdered flame retardant enters the glue mixing machine together with the shavings, and is transported to the paving machine after sizing, paving, pre-pressing, hot pressing, and sanding to make fire retardant particle board. Part of the flame retardant is covered by the adhesive, which has little effect on the physical and chemical properties of the product. The flame retardant and the shavings are bonded together by the adhesive, and the distribution is uniform, and it will not be concentrated on the surface of the slab during paving.

This method uses airflow paving equipment to pave a certain amount of flame retardant into the slab before forming the fire retardant particle board. This method can not only avoid the loss of flame retardant during sanding, but also make the minimum amount of flame retardant volatilize to maximize the flame retardant effect.
