Product Introduction
Bulletproof and explosion-proof laminated glass is a high-grade safety glass made of two or more layers of glass with bonding materials (such as polyvinyl butyral PVB or vinyl acetate polymer EVA interlayer, etc.) sandwiched between them. This structure allows the glass to remain in the frame even if it is broken when it is impacted by external forces, preventing glass fragments from splashing and injuring people.
Manufacturing Process
Raw material preparation: Select high-quality glass sheets and low-iron raw materials, as well as transparent organic polymer interlayer materials.
Tempering treatment: The glass sheets are heated at high temperature and cooled quickly to form uniform compressive stress inside, thereby improving its impact strength and bending strength.
Interlayer production: Add one or more layers of transparent organic polymer interlayer materials between tempered glass. These materials can melt and fill the gaps between the glass at high temperatures to form a strong interlayer structure.
Inspection and packaging: The finished transparent interlayer tempered low-iron tempered glass is strictly inspected to ensure that its various performance indicators meet the requirements. Then, the glass is packaged for transportation and installation.
Product Specifications
The specifications of bulletproof and explosion-proof laminated glass vary depending on the manufacturer and application scenario. Generally speaking, the total thickness is required to be above 20mm, while the total thickness of bulletproof and explosion-proof glass with higher requirements can reach above 50mm. The production thickness range is usually between 5mm and 60mm.
Application
Bulletproof and explosion-proof laminated glass is widely used in the following fields due to its excellent bulletproof, explosion-proof and safety performance:
Security places: such as banks, financial institutions, units and agencies, etc., used on isolation devices such as windows and doors to improve safety.
Transportation tools: such as cars and airplanes, used in key parts such as windshields and rearview mirrors to improve passenger safety.
Important buildings: such as embassies, museums, exhibition halls, etc., used to protect precious cultural relics and exhibits from damage.
Product Features
Bulletproof and explosion-proof performance:
Bulletproof: The use of multiple layers of interlayers can produce multi-level bulletproof glass, which can effectively resist the impact of bullets.
Explosion-proof: Even if the glass is broken, it will not fall to the ground as a whole, and it will remain in place to prevent the explosion fragments from causing damage to people and property.
Safety:When the bulletproof and explosion-proof laminated glass installed on the building is impacted by any external force, even if the glass is broken, it can still remain intact on the original frame, avoiding the flying glass fragments from causing harm to people inside and outside the building.
Hurricane and earthquake protection:Bulletproof and explosion-proof laminated glass can provide additional protection and reduce the risk of glass breaking in extreme weather conditions (such as hurricanes) and earthquakes.
Ultraviolet protection:It has a great blocking effect on ultraviolet rays in sunlight, with an ultraviolet blocking rate of more than 99%, preventing ultraviolet radiation from damaging indoor furniture, floors, etc.
Noise reduction:The bonding material (such as PVB film) has a blocking and absorbing effect on sound waves, thereby reducing noise and improving the comfort of the indoor environment.

FAQ
Q. Will the performance of bulletproof and explosion-proof laminated glass deteriorate over time?
A: The performance of bulletproof and explosion-proof laminated glass usually does not deteriorate significantly over time, provided that it is properly maintained and cared for. However, if the glass surface is severely scratched, impacted or contaminated, its bulletproof and explosion-proof performance may be affected. Therefore, regular inspection and maintenance are essential.
Q. Will bulletproof and explosion-proof laminated glass shatter after being impacted?
Answer: When bulletproof and explosion-proof laminated glass is impacted, its outer layer of glass may break, but due to the presence of the middle interlayer, the glass fragments will be firmly adhered to the interlayer and will not splash and injure people. At the same time, the interlayer itself also has a certain elasticity, which can absorb and disperse the impact energy, thereby protecting the safety of people and property.
Q3. Can bulletproof and explosion-proof laminated glass withstand high temperatures and fires?
Answer: The effects of high temperatures and fires are usually taken into account during the design and manufacturing process of bulletproof and explosion-proof laminated glass. Although it cannot completely resist the damage of high temperature and fire, it can slow down the spread of fire to a certain extent, and win precious time for personnel evacuation and fire fighting. However, long-term exposure to high temperature may have a certain impact on its performance, so it should be evaluated and selected according to the specific application scenario.
Q4. How to clean and maintain bulletproof and explosion-proof laminated glass?
Answer: When cleaning bulletproof and explosion-proof laminated glass, you should use a soft cloth and neutral detergent, and avoid using detergents containing abrasive particles or strong acid and alkali. At the same time, you should avoid using sharp tools such as metal scrapers to clean it to avoid scratching the glass surface. In terms of maintenance, the scratches, contamination and looseness of the glass surface should be checked regularly, and they should be handled and replaced in time.
Q5. Is the price of bulletproof and explosion-proof laminated glass high?
Answer: The price of bulletproof and explosion-proof laminated glass is usually higher than that of ordinary glass, because special materials and processes are required in its manufacturing process to ensure that it has high performance such as bulletproof and explosion-proof. However, considering the security it provides and its long-term use value, its price is also relatively reasonable. When choosing, you should weigh and choose according to the specific application scenario and budget.
Q6. Can bulletproof and explosion-proof laminated glass be used for home decoration?
Answer: Although bulletproof and explosion-proof laminated glass is mainly used in places with high security requirements, it can also be considered for use in home decoration. Especially for families with children or pets, the use of bulletproof and explosion-proof laminated glass can increase the safety of the home. However, it should be noted that its price is relatively high and the installation and maintenance costs are relatively high, so decisions need to be made based on personal needs and budget.
