The manufacturing principle of security glass mainly includes the following aspects:
1. Multi-layer structure: Security glass consists of two or more layers of glass alternating with one or more layers of interlayer material. The interlayer material is usually a high-strength plastic film such as PVB (polyvinyl butyral) or ion-exchange plastic.
2. High-pressure bonding: Under high temperature and pressure, the glass and interlayer material are tightly bonded together to form a solid whole.
3. Enhanced impact resistance: The elasticity and adhesive properties of the interlayer material allow the glass to adhere to the film even if it breaks, preventing it from scattering and thus improving its impact resistance.
