Our country new heat-resisting performance one hour up to nine hundred and ninety-nine degrees Celsius flameproof glass grave
2012.11.15, Shanghai occurrence of a catastrophic fire, fire safety once again attracted the public attention and discussion. In order to avoid such tragedies from happening again, the general public immediately put forward demands for the common people can also be installed on can block the fire from spreading fire window it? You can replace withstand fire scorched more powerful fire monolithic glass it? Three days later, the high-tech China Construction Metal Structure Association conference held in Beijing spread the gospel, a thousand degrees Celsius burning still maintain more than one hour is not burst, maintain good integrity monolithic fire-resistant glass, complete to achieve the fire safety requirements of home life. Residents to install the glass, which can effectively prevent the spread of fire and smoke, as in the scene of the fire and evacuate people trapped firefighters rescue to win precious time. The chemistry of new technology for the manufacture of monolithic fire-resistant glass, bullet-proof glass played a key role.
China Construction Metal Structure Association official said, using a single fire outside the building window glass is to raise the level of an important part of building fire, fire-resistant glass as a material to improve building fire rating requirements, has been used as an important indicator of building fire safety standards. This new technology though not yet the majority of people are familiar with, but it has become the focus of professional fire people and designers to fire safety concerns. Beijing "Bird's Nest" National Convention Center, Shanghai World Expo Performing Arts Center, Shanghai Passenger Transport Center, Shanghai Super Brand Mall, Shanghai Metro Line 6 to 11, Tokyo "chrysalis" building, the Knesset building, and so many iconic international influence public construction, have adopted this particular fire monolithic glass, bullet-proof glass.
Since "11 • 15" fires so far, the Shanghai authorities often receive many residents want to install fire-resistant glass upon request. According to the China Construction Metal Structure Association introduced a monolithic fire glass combination of new technologies, can greatly improve the overall performance of a building fire. The new products will become home to improve the fire rating, conducted renovation of choice.
It is understood that, as a general construction outside the window openings of the external structure of the building is an important channel up the spread of the fire thermocline. Therefore, the fire protection for windows is to enhance the building fire can not be ignored important part of its fire performance become important landmarks fire rating. With the rapid increase in urban high-rise residential buildings, high-rise building fire has become an important issue. Height of fire rescue equipment is limited, it is often difficult to start rescue work surface, as well as affect the timely implementation of fire fighting and rescue operations personnel. Therefore, to improve the fire rating of windows, effectively prevent the fire spread rapidly and become an important measure to reduce fire losses and casualties. Fire glass high-rise buildings has become an important means to prevent the spread of fire between floors.
At present, the building exterior windows, curtain wall glass used diverse as monolithic fire-resistant glass, bullet-proof glass, laminated glass, hollow glass. Although the performance of these glasses vary, but not with fire resistant function, in case of fire, the glass will be broken in a very short period of time to form a flame channel, the fire spread rapidly, so that people's lives and property suffered very serious threat. The large fire monolithic glass by molten alkali metal ions displace sodium ions of the glass surface of this chemical method, the glass surface more stress, not only to enhance the high-temperature performance of the material, significantly improved fire performance, but also improve the mechanical strength , with the thickness of fire-resistant glass is float glass of 6 to 12 times the strength of glass of 1.5 to 3 times. And this fire-resistant glass, both energy, economic, and security, and environmental protection.
Tests show that at 1000 ℃ fire burning grill, ordinary float glass breakage damage time is only one minute, tempered glass is five minutes, the two glass basically do not have fire safety features. The fire monolithic glass baking at 1000 ℃ flame burning for 60 minutes or more can not burst, maintain good integrity, so as to effectively prevent the spread of fire and smoke.
Monolithic fire glass price will not be very high, the general public family can afford to install them? Monolithic fire glass area of windows is typically about 1/10 of the total residential area, press estimates, a building area of 100 square meters of residential windows and doors area of 10 to 15 square meters, compared with the other glass, installation of fire Glass just more spending 3,000 to 5,000 yuan, while the family life and property posed security is far less able to measure these money.
It is understood that the national real estate New Deal have been put forward to reduce the demand for glass, the other backward production capacity of flat glass has been included in the list last year phase-out of the building materials industry. Atrophy architectural glass market, a direct result of product sales decreased upstream soda, soda ash industry loss expanded. Building fire accident prevention, promote the use of laminated glass new fire monolithic glass came into being, which not only promotes the building materials enterprise crises into opportunities, adjust product structure, but also to chemical companies see hope.
