扁平化插画风木材阻燃过程示意图

Scientific mechanism diagram illustrating the P-N-B synergistic flame retardancy of wood under fire. Split into three phases: Left side (Heating) shows ATMP molecules releasing ammonia (NH3) and water vapor to dilute oxygen; Middle (Pyrolysis) shows Phosphorus (P) catalyzing wood dehydration to form a dense char layer; Right side (High Temp) shows Borax (BX) forming a glassy B2O3 protective layer covering the char.Visual Elements: Microscopic view, atomic and molecular models, semi-transparent wood cell wall background. Color code: Phosphorus (P) as orange, Boron (B) as pink, Nitrogen (N) as blue.Style: Infographic, flat vector style, clean lines, chemical structures, high quality, white background.
