Composite fire-resistant glass is a general term for fire-resistant glass processed by composite methods. Among them, hollow fireproof glass, laminated fireproof glass, cast fireproof glass, and laminated fireproof glass are widely used. The above-mentioned glass is mostly composed of two or more layers of glass composite or one layer of fire-resistant glass composite with organic materials, in order to achieve fire-resistant glass with a certain fire resistance rating.
With the development of the times, the research and development of different product combinations and new processes have produced new types of composite fire-resistant glass. The new composite fire-resistant glass is made by adjusting the composition of the fire-resistant adhesive and using a dry wet process
Wet insulated composite fireproof glass
Main materials: fireproof glass raw board or other glass, fireproof silicone. Use two or more glass sheets and pour a single or multiple layers of new fire-resistant adhesive in the middle. Seal the surroundings with special flame-retardant adhesive, and bond the fireproof adhesive and glass together through physical methods such as air drying. Unlike previous flame retardant liquids, this flame retardant adhesive has stronger fire resistance and thermal insulation properties. The fire-resistant integrity of insulated fire-resistant glass made of single-layer fire-resistant silicone can reach 1 hour, while the fire-resistant integrity of insulated fire-resistant glass made of double-layer or multi-layer can reach 1.5 hours.
Dry - process Heat - Insulating Composite Fire - Resistant GlassCombination structure: 5mm tempered glass + 1mm fire - resistant adhesive + 3mm float glass + 9A + 5mm tempered glass, with a thickness of 23mm and above. Although the surface is made of ordinary glass, the glass - clad components obtained by combining dry - process heat - insulating composite fire - resistant glass with metal frames (such as aluminum alloy) have passed the inspection of the National Architectural Quality Supervision Center, and the fire resistance integrity is ≥ 61min.
Single - layer Fire - Resistant Silicone Heat - Insulating Composite Fire - Resistant GlassCombination structure: 6mm tempered single glass + 10mm fire - resistant silicone + 6mm tempered single glass. Due to the excellent fire - resistant performance of fire - resistant silicone, the single - layer fire - resistant silicone heat - insulating fire - resistant glass meets the specification conditions in the quality supervision and inspection center of fire - resistant components and the fixed fire extinguishing system inspection: when the fire test is carried out for 60 minutes, it still maintains fire resistance integrity without cracking; at the same time, it maintains heat insulation: the temperature rise on the back surface only reaches 63.7°C, and the single - point temperature rise only reaches 70.1°C.
Double - layer Fire - Resistant Silicone Heat - Insulating Composite Fire - Resistant GlassCombination structure: 5mm tempered single glass + 7mm fire - resistant silicone + 5mm tempered single glass + 7mm fire - resistant silicone + 5mm tempered single glass, with an overall fire - resistant glass thickness of about 30mm. According to experience, the thicker the composite fire - resistant glass, the better the fire resistance. Similarly, the double - layer fire - resistant silicone composite heat - insulating fire - resistant glass was sent to a professional institution for inspection. When the fire test was conducted for 90 minutes, it still maintained fire resistance integrity and heat insulation: the temperature rise on the back surface of the test piece only reached 64.7°C, and the maximum single - point temperature rise was 80.1°C.
The above new - type composite fire - resistant glasses are the products of the development of the times and the improvement of building fire protection requirements. We should not choose fire - resistant glasses blindly. Purchasing according to the actual needs of the project is the basic concept, and passing the construction acceptance inspection is the goal.
