Steel super fire shutter

TFJ(G) type steel super-grade fire shutter, according to the GB50045-95 "Code for Fire Protection Design of High-rise Civil Buildings": "When a fire shutter that does not include the temperature rise of the back fire surface as the fire resistance limit judgment condition is adopted, both sides of the shutter shall be protected by an independent closed automatic water spray system, and the water spray duration of the system shall not be less than 3.0h", a new product developed considering the needs of fire prevention. The Ministry of Public Security "National Fire Building Materials Quality Supervision and Testing Center" of the inspection, the average water flow of 1.30 m3/h, fire resistance time 240min, performance reached the advanced level at home and abroad. The curtain of this product is made of double-layer galvanized steel plate and filled with aluminum silicate fiber cotton composite rolling. The surface is electrostatically sprayed and pressed with X-shaped grooves. The curtain surface is evenly distributed with water and has a long water retention time, so as to ensure the requirements of lower temperature and radiation protection and improve the fire resistance limit of fire-resistant roller shutter. In addition to excellent fire resistance performance, it also has the following characteristics: 1. It only occupies the upper space, good mechanical performance, reasonable structure, flexible opening and closing. 2. High tensile strength: corrosion resistance and moisture resistance. 3, the shutter door opening and closing can be linked with the fire control center, can also be independent unit, by the smoke, temperature detector to provide action signal and separate opening and closing. It has both automatic and manual opening and closing functions.

Product Introduction

TFJ(G) type steel super-grade fire shutter, according to the GB50045-95 "Code for Fire Protection Design of High-rise Civil Buildings": "When a fire shutter that does not include the temperature rise of the back fire surface as the fire resistance limit judgment condition is adopted, both sides of the shutter shall be protected by an independent closed automatic water spray system, and the water spray duration of the system shall not be less than 3.0h", a new product developed considering the needs of fire prevention. The Ministry of Public Security "National Fire Building Materials Quality Supervision and Testing Center" of the inspection, the average water flow of 1.30 m3/h, fire resistance time 240min, performance reached the advanced level at home and abroad. The curtain of this product is made of double-layer galvanized steel plate and filled with aluminum silicate fiber cotton composite rolling. The surface is electrostatically sprayed and pressed with X-shaped grooves. The curtain surface is evenly distributed with water and has a long water retention time, so as to ensure the requirements of lower temperature and radiation protection and improve the fire resistance limit of fire-resistant roller shutter. In addition to excellent fire resistance performance, it also has the following characteristics: 1. It only occupies the upper space, good mechanical performance, reasonable structure, flexible opening and closing. 2. High tensile strength: corrosion resistance and moisture resistance. 3, the shutter door opening and closing can be linked with the fire control center, can also be independent unit, by the smoke, temperature detector to provide action signal and separate opening and closing. It has both automatic and manual opening and closing functions.

Scope of application:

Steel super fire shutter has the characteristics of good fire resistance, simple structure, corrosion resistance, wind pressure resistance, and anti-theft. It is widely used in partitions that require fire protection in various industrial and civil buildings. It is mainly used in:

1. The place where the temperature rise of the back fire surface needs to be measured;

2, a large area of fire prevention area partition, there are people and goods through the place.

3. Places with fire prevention and theft prevention requirements:

4. Places with high wind pressure requirements: such as industrial plants, hotels, warehouses, waiting (car) buildings, libraries and other places.

Main parameters

1. Fire resistance limit: the radiant heat intensity of the back fire surface is 0.3 w/cm2, the average temperature rise ≤ 75°C, and the fire resistance limit is greater than 4.0h.

2. Wind pressure resistance: when the wind pressure is 784.5Pa, the central deflection of curtain plate is less than 45mm (international)

3. Average water distribution strength ≤ 216L/m2, min, average water flow 1.30m3/h, water supply pressure ≥ 0.1MPa

4. Motor power: 0.25-0.75Kw

5. Power supply: AC 380v,50HZ: control power supply: DC 12-24V.

6. Opening and closing speed: rising speed 2-9 m/min, falling speed 2-9 m/min, self-weight falling speed 4-9 m/min
