Research on thermal stability of new-style foamed gel

Common fire-prevention materials cannot be filled quickly and are toxic, corrosive and low efficiency. In order to solve the disadvantages of these common materials as well as to improve the efficiency of anti-extinguishing, a better coagulant was selected for developing a new type of environmentally friendly foamed gel. The results show that the dehydration rate of foamed gel accelerated with increasing temperature; The foamed gel in various stages of different temperatures meet different dynamics characters and mainly affected by the surface control and diffusion control; The complete dehydration time formula can be used to estimate complete dehydration time of foamed gel within a specific range; The differences in the physical properties made foamed gel a better evaporation-water loss rate than gel. So the new-style foamed gel is an effective anti-extinguishing material with good thermal stability.
