1. Product introduction of fireproof glass
Fireproof glass is a special safety glass that can maintain stability in a high-temperature fire environment and prevent the spread of flames and smoke. The goal is to maintain the integrity and thermal insulation of the building for a specific period of time, protecting the lives of people. The fire rating of fireproof glass is divided according to its fire resistance limit, and the common grades include 30 minutes, 60 minutes, 90 minutes and even 120 minutes.
According to the structure and function, fireproof glass is mainly divided into Class A heat-insulating fireproof glass (EI class) and C-class non-heat-insulated fireproof glass (E class), in which heat-insulating fireproof glass not only blocks flames, but also can effectively insulate heat, while non-heat-insulating type mainly prevents the spread of flames.

2. Product Compounding Process (Machinable Type)
Fire-resistant glass can be produced through a variety of lamination processes, common including:
· Monolithic fireproof glass: It is treated with special high temperatures to maintain its integrity in the event of a fire, and is generally used to stop flames and smoke.
· Laminated fire-resistant glass: A fire-resistant layer (e.g. fire-resistant film or refractory fluid) is sandwiched between two or more pieces of glass to improve thermal insulation.
· Insulating fireproof glass: Combine fireproof glass with ordinary glass to form sound insulation and thermal insulation effects, which is suitable for architectural design with comprehensive requirements.
· Tempered fireproof glass: through high-temperature tempering treatment, the impact resistance is increased, and it is not easy to break and splash in the fire.
These composite processes combine advanced glass manufacturing techniques to ensure that the strength, stability and thermal insulation of the glass are maintained in the event of a fire.

3. The minimum processing thickness of fireproof glass
Depending on the fire rating, the minimum processing thickness of fireproof glass is usually 6mm, but to ensure a high fire resistance limit and thermal insulation performance, the common thickness is 8mm to 60mm. The actual thickness will be adjusted according to the fire time rating and the specific application.

5. Use
Fireproof glass is widely used in places with high requirements for safety and fire protection, including:
· Public buildings: such as airports, shopping malls, schools, museums
· High-rise buildings: used for fire doors, partition walls, stairwells, etc
· Industrial facilities: such as fireproof windows and firewalls in factories and laboratories
· Special buildings: used in elevator shafts, fireproof curtain walls, emergency passages, etc
In addition, fire-resistant glazing is often used in curtain wall and skylight structural systems that require strict fire protection requirements.
