Explosion-proof glass, as a high-strength and high-safety glass material, is widely used in construction, transportation, and other fields. To ensure its safety and stability during use, explosion-proof glass needs to meet a series of load-bearing standards.
Impact Resistance
Blast-proof glass must be able to withstand a certain amount of impact force without breaking. According to international standards, blast-proof glass must be able to withstand an impact force equivalent to at least 1000 Newtons. Higher-level blast-proof glass, such as Class IV blast-proof glass, can even withstand the powerful impact of a 1.8kg steel ball dropped freely from a height of 9m. This impact resistance is achieved through special design and manufacturing processes, including the addition of reinforcing mesh or thin films within the glass.
Penetration Resistance
In addition to impact resistance, blast-proof glass must also have good penetration resistance. When subjected to external impact, blast-proof glass is not easily penetrated, effectively protecting the safety of people and property. This performance is usually determined through tests using representative steel balls or bullets.
Pressure Resistance
Blast-proof glass also needs to withstand a certain amount of pressure to prevent breakage due to pressure. According to international standards, blast-proof glass must be able to withstand a pressure equivalent to 2000 Newtons without breaking. This pressure resistance is determined by applying pressure for a certain period of time and observing the results.
Other Performance Standards In addition to the load-bearing standards mentioned above, explosion-proof glass also needs to meet other performance standards, such as tensile strength, high-temperature resistance, corrosion resistance, and optical properties. These performance standards are all designed to ensure the safety and stability of explosion-proof glass during use.
