1, can withstand a large bomb explosion impact load;
2. After the bomb explosion, the glass remains in the frame.
Anti-bomb glass combination:
Type A: DFB8+ polymer material + DFB8
8mm high strength single piece strontium potassium fireproof glass + polymer material + 8mm high strength single piece cesium potassium fireproof glass
Type B: DFB10+ polymer material + DFB10
10mm high strength single piece strontium potassium fireproof glass + polymer material +10mm high strength single piece cesium potassium fireproof glass
Anti-bomb glass and other glass anti-explosion contrast:
When ordinary glass (annealed, tempered, semi-tempered) is hit by a bomb explosion, glass fragments are scattered, the glass is penetratingly damaged, and people and indoor facilities are seriously injured. RET≈0-0.2.
When the ordinary laminated glass is impacted by a bomb explosion, the glass breaks and the shock wave enters the room. In severe cases, the whole broken glass flies up, causing serious damage to the human body, and the overall damage range is smaller than that of ordinary glass. RET ≈ 0.3-0.5.
When the bomb-proof glass is impacted by a bomb explosion, the glass is bent backwards, while the frame system compresses and cushions backwards. The glass is intact or cracked, but substantially no debris is spilled to ensure that the indoor personnel and facilities are not harmed. RET≈1.0.
Note:
RET: Hold value, indicating the overall retention of the glass within the frame.
RET = glass weight after explosion impact / glass weight before explosion impact
When RET=1.0, the whole glass remains in the frame, the fragments are not scattered, and the glass does not penetrate;
When RET = 0, the whole piece of glass leaves the frame, the fragments are scattered, and penetrating failure occurs.
The polymer is generally PVB, and there are other kinds of transparent bulletproof films, but PVB is a commonly used material.
