High strength function of outdoor fireproof glass

High strength monolithic fireproof glass not only has excellent fireproof function, but also has better strength. Under the same thickness, its strength is 6-12 times that of float glass and 1.5-3 times that of tempered glass.

Compared with traditional grouted or laminated fireproof glass, high-strength monolithic fireproof glass is characterized by high weather resistance in addition to high strength.

Chemical grouting or laminated fireproof glass will soon become milky white and bubble under ultraviolet irradiation, losing the basic function of glass permeability, which is also the main reason why fireproof glass can not be used as a wall for a long time.

High strength monolithic fireproof glass is the same as ordinary glass. There is no change under infrared irradiation.

It can be processed into laminated safety glass, insulating glass, coated glass, point curtain wall glass and hot bending fireproof glass. It can also be used as an indoor fire prevention distance and escape passage. It has a large break in the single use area, and can reach a height of 9m x a width of 2.4m.

The installation method is also simple and easy to understand, close to general glass.

General glass curtain walls are easy to break when they are burned or heated. Float glass burst in one minute when exposed to fire, and tempered glass burst in one minute when exposed to fire, forming a rapid extension of the fire, becoming a large fire and a "fire air duct". Therefore, the fire prevention measures that should be adopted for glass curtain wall are regulated in the relevant national engineering planning and fire prevention specifications. According to article 3.0.8 of the current national code code for fire protection planning of high rise civil buildings (gb50045), the setting of glass curtain wall shall comply with the following rules: ① the filling data of window wall and window olive wall shall be non combustible data. When the non combustible body with a fire resistance limit of not less than 1.00h is selected for the outer wall, the data filled in the wall can be difficult to burn. ② For the glass curtain wall without window wall and window parapet wall, a non combustible solid skirt wall with a fire resistance limit of not less than 1.00h and a height of not less than 0.80M shall be set at the outer edge of each floor. ③ The gap between the glass curtain wall and each floor slab and partition wall shall be tightly filled with non combustible materials.

Such structural treatment can effectively avoid the rapid extension of fire in the straight direction, but its negative impact is that the interlayer distance composed of skirt wall with a height of 800mm and fireproof rock wool seriously affects the visual effect of glass curtain wall, changes the original intention of planning glass curtain wall, and makes the architectural style different.

The emergence of new high-strength single piece cesium potassium fireproof glass provides us with a practical treatment method to kill two birds with one stone. Class C class I and class B class I fire resistance time requirements in accordance with gb15763.1-2009 safety glass and fireproof glass for buildings.

Fire prevention function

In modern architecture, there are various kinds of glass used for building envelope. For example, tempered glass, laminated glass, insulating glass, float glass, coated glass, etc. These are the different functions of glass, but the types of these glasses do not have the function of heat-resistant and fireproof glass. Once a fire breaks out, the glass will break in a very short time, so that the fire can be extended, and everyone's life safety and industry will be severely threatened.

High strength monolithic cesium potassium fireproof glass is a kind of curtain wall or door and window glass for building exterior wall with fireproof function. It is obtained by treating float glass with special technology.

It can hold for 80-120 minutes in 1000 ℃ flame, and then effectively block the extension of flame and smoke, which is conducive to discovering the fire at the first time, enabling everyone to evacuate the site for a long time and carry out disaster relief work.

The appearance of outdoor fire-proof glass solves the fatal disadvantage of poor fire safety of general glass exterior wall, and greatly improves the safety factor of glass exterior wall.
