Flame retardants What are the ways that flame retardants can be used?
Many friends said that they would not use flame retardants, do not know how to use flame retardants for flame retardant, it doesn't matter, here, Xiaobian to teach you, how to use flame retardants for flame retardant, to achieve the effect of flame retardant.
1. Atmospheric immersion method:
Wood is impregnated in a low viscosity flame retardant solution at room temperature or under heating conditions. The length of immersion time depends on the required flame retardancy and wood properties. Generally, when the drug loading reaches 32~ 80kg/m3, the flame retardant effect can be reached.
Keep an eye on:
1, atmospheric pressure impregnation method can only soak into the wood about 6-lOmm.
2, but it is only suitable for thin plate, as well as better soaking base raw materials.
Two, vacuum high pressure impregnation method
Vacuum high pressure impregnation method:
The wood is placed in the high pressure tank, and the vacuum pump is used to form a certain negative pressure, so as to remove the gas in the wood cell cavity, and then through the vacuum inhalation of wood flame retardant liquid, and then through the pressure equipment to apply a certain pressure to the tank, the flame retardant liquid is pressed into the wood cell and then to the flame retardant effect.
