How to use flame retardant

Different flame retardants are used in different ways. Use method of wood flame retardant Flame retardant method of wood flame retardant-atmospheric pressure impregnation method Atmospheric impregnation method: Wood is soaked in flame retardant solution with low viscosity at room temperature or under heating condition, and the soaking time depends on the required flame retardant degree and wood properties. Generally, when the drug loading reaches 32~ 80kg/m3, the flame retardant effect can be achieved. Note: 1. The normal pressure impregnation method can only penetrate into wood for about 6~ lOmm. 2. However, it is only suitable for thin plates and materials with good permeability.
