How to use flame retardant

Different flame retardants are used in different ways.






Application of wood flame retardant






Flame retardant method of wood fire retardant atmospheric pressure impregnation method






Atmospheric pressure impregnation method:






Wood is impregnated in a low viscosity flame retardant solution at room temperature or under heating conditions. The length of impregnation depends on the degree of flame retardancy required and the wood properties. Generally, when the drug loading is 32 ~ 80kg / m3, the flame retardant effect can be achieved.






be careful:






1. Atmospheric pressure impregnation can only penetrate into wood about 6 ~ 10 mm.






2. But it is only suitable for thin plates and materials with good permeability.
