Bulletproof structure and type

Bulletproof glass structure: First, we need to understand the basic structure and types of bulletproof glass. Since bulletproof glass is also a laminated type, we can see that most of the bulletproof glass structure is similar to the picture below, for example, three or more layers of glass are glued Crafted,

Bulletproof glass types: all glass type、composite polycarbonate bulletproof glass、and special types are shown in the following picture. The comparison of bulletproof glass grades between the same thicknesses, all glass type <special bulletproof glass <composite polycarbonate bulletproof glass grade According to the UL752 standard and the GA165 bulletproof glass standard, it can be understood that the grade of bulletproof glass is related to its test performance.

Bulletproof glass material

Through the above structure and types, we can understand that common materials for bulletproof glass are ordinary non-tempered glass and intermediate glue materials (commonly PVB film) can be combined into all-glass type bulletproof glass, and if the material contains polycarbonate composite materials, it can be combined into The composite bulletproof glass can be summarized as: glass + PVB + glass +... (PVB/polycarbonate+polyurethane) + glass + bulletproof film through the appeal structure.

Bulletproof glass cost

Because the cost of raw materials is different, the cost of bulletproof glass can be calculated by knowing the model, grade and type of bulletproof glass. The cost of all-glass bulletproof glass is relatively simple, mainly because the manufacturing cost of ordinary glass and PVB film are combined. The bulletproof glass containing polycarbonate composite material is represented by the cost of polycarbonate material plus the cost of glass and the cost of film
