Effect of hygroscopicity of fire retardant on hygroscopicity of fire retardant bamboo chips
This paper presents a study on the effect of hygroscopicity of fire retardant on the hygroscopicity of fire retardant materials (bamboo chips). The results showed that the hygroscopicity of fire retardant and fire retardant bamboo chips increased with increasing fire retardant concentration, and the suitable range of fire retardant concentration is 20- 30 %; the hygroscopicity of fire retardant and fire retardant bamboo chips increased with the increasing of drug loading rate of fire retardant bamboo chips, and the suitable drug loading rate is 10.2 %; the hygroscopicity of fire retardant bamboo chips increased with the increase of the hygroscopicity of fire retardant, and the hygroscopicity of fire retardant bamboo chips is smaller when treated with the fire retardant whose water absorption rate less than 18 %.
