Monolithic cesium-potassium fire-resistant glass
Monolithic cesium-potassium fire-resistant glass is a kind of curtain wall, door and window glass for building exterior walls with fire-resistant function. It is made by using a special process to chemically and physically enhance the float glass. It can keep for 80-120 minutes without bursting in a flame of 1000℃, thus effectively preventing the spread of flames and smoke. It is conducive to discovering the fire early, so that people have enough time to escape and leave the scene, and to carry out disaster relief work.
Characteristics of monolithic cesium potassium fireproof glass:
1. Excellent fire resistance, it can maintain integrity without breaking within the fire resistance time limit, and can prevent the spread and spread of flames and smoke.
2. The strength is 6 to 12 times that of float glass of the same thickness and 1.5 to 3 times that of tempered glass.
3. Deep processing: it can be processed into hollow fireproof, laminated fireproof, coated fireproof glass, etc.
4. Safety: The integrity is maintained within the fire-resistant time limit. When the fire-resistant time limit is exceeded, the glass will soften, and when it is impacted and broken by external force, the particles are extremely small and not easy to hurt people.
5. Anti-aging: heat resistance, cold resistance, humidity resistance, light resistance, etc.
There are five main types of fireproof glass, one is laminated composite fireproof glass, the other is wire fireproof glass, the third is special fireproof glass, the fourth is hollow fireproof glass, and the fifth is high-strength single-layer cesium potassium fireproof glass. In the past two years, several major fire accidents have occurred in China, such as the North Annex Building of the new CCTV site and high-rise residential buildings in Jing'an District, Shanghai, causing serious losses and harm. The country has carried out a wide range of fire safety inspections, and the people's awareness of fire protection has been gradually improved. Fire-resistant glass has the advantages of retarding the spread of fire, heat insulation, and smoke isolation. It can create favorable conditions for the rescue of personnel, property and buildings when a fire occurs, and minimize losses. It is favored by the people and has the potential of the fire-resistant glass market.
Fireproof glass is a new type of building fireproof material, which is mainly used to make fireproof doors, firewalls, fireproof partitions, etc. In Europe, fireproof glass is divided into monolithic integral type and composite insulation type fireproof glass. From the classification of fire resistance performance, fireproof glass can be divided into three grades: 30 minutes, 60 minutes and 90 minutes. Single-piece complete fire-resistant glass is a fire-resistant glass constructed from a single layer of glass, which is mainly used for partitions, fire compartments, outdoor curtain walls and other building parts of large public buildings. After a long time high temperature ion exchange chemical treatment process, single-piece fireproof glass has the advantage of low thermal expansion rate. It can keep the glass soft and not broken at high temperature for a period of time. By maintaining the integrity of the glass, it prevents the open flame on the fire side and is toxic. Harmful gases, etc., but cannot be insulated from heat. In addition, in addition to fire-resistant glass, the importance of glass frames should also be emphasized. If the frame is not fireproof, it is easy to soften and deform in the event of a fire, and even the best fireproof glass will not play its due role. Therefore, it is also very important to equip the corresponding fireproof frame installation accessories.
