The smoke wall is the passive fire protection equipment adopted by most countries in the world. The purpose is to control the spread of the disaster caused by the spread of smoke under fire conditions. There are three basic classifications: the fixed smoke wall and the wall. Plate-type smoke wall, curtain-type smoke wall (wind curtain). The smoke block body of the smoke curtain wall is a block cloth.

Smoke curtain wall cloth is usually made of glass fiber coated silica cloth, the quality of which depends on several factors: the quality of the cloth, the quality of the glue, and the use of high quality alkali-free glass fiber cloth is the strength of the smoke curtain wall cloth The guarantee is also the guarantee of delaying embrittlement at high temperatures; the use of high-quality silica gel is a guarantee that the smoke wall will not burn at high temperatures of 600°C!

The basic requirements for the smoke detection of the smoke wall of the BS EN 12101-1-2005+A1-2006 standard are: After passing preliminary air permeability and strength tests, it is necessary to provide two sets of gears of 3m*6m and 3m*10m. The smoke wall was first tested for 2,000 windings. After passing through, a 3 m * 3 m smoke wall was intercepted on a smoke wall that had been wound up for 2000 times. The fire resistance test was performed. °C for half an hour to maintain fire integrity.

Beijing Feifufu's customers conducted an annual recheck of the smoke wall in Singapore this year. Beijing Feifufu Engineering Technology Co., Ltd. provided the smoke-hanging wall cloth, and customers sewed and produced machinery, transmission, and control equipment. Singapore conducted a sample test and successfully passed the test.

The BS EN 12101-1-2005+A1-2006 standard has been adopted in many regions such as Europe, Southeast Asia, etc. The test passed this standard means that it is possible to implement the smoke-blocking wall project in these areas.

Beijing Feifufu owns the finished textile and coating production line for high-temperature textiles, and has complete fire-resistance and strength laboratories. The technical team launches new research and development projects every year, and has many patented technologies in the fields of heat insulation, heat preservation, sealing, and fire protection.

To do fire is to do conscience, do insulation is to do merit!
