Fire curtain easily exist quality problems of some fire shutter refers to a certain period of time, together with a framework to meet fire resistance and fire stability requirements of the shutter. Fire shutter is an active fire compartmentation, usually rolled up in window and door hinges tank outlet, it put down when the fire started, to prevent fire spread from the door and window openings. By curtain panels, Rails, doorway, block, plate, gearing, shutter, control box, etc. Fire shutter is widely used in various industrial and civil buildings, once the fire occurs, turn off automatically, the blocked fire smoke spread, for the time and reduce fire injuries and economic loss. In the fourth quarter of 2006, in Henan province fire curtain production units for cars and found the overall fire shutter product quality is good, but there are some quality problems: 1, material inspection, thickness of the main parts of the raw material is not up to standard requirements such as seat plate thickness of steel sheet required 3.0mm, some manufacturers have used the thickness of plate 1.0mm, this will cause the seat plate stiffness, easy extrusion. 2, rail inspection, most manufacturers of parallelism error and vertical alignment error does not satisfy the standard requirements, resulting in a larger Middle gap, fire smoke measures will lose its effect. 3. seat Board examination, some manufacturers of fire shutter cannot contact with the ground, in the event of fire, flames from the base plate and the ground, the fire spread to other parts of the site, you cannot prevent the spread of fire smoke, no fireproofing function. 4. fire shutter manufacturers generally have no drawings production. Most of the enterprise in order to facilitate, in accordance with the size of door opening, Assembly and installation, drawing, resulting in low quality installation. Quality problems due to the above there are many reasons, however, the most important are: 1, the installation team low quality, the level is not high, particularly in order to catch the duration temporary deployment of Installer, installation quality is not stable. Therefore, the enterprise should increase installation team building and enhancing its installation level, achieve the goal of improving product quality. 2. each producer cannot project reality drawing, and organize production installation. To this end, the enterprise should be based on the actual situation of engineering drawings and shutter control of production quality, while at the same time increase the installation team building and enhancing its installation level, thereby enhancing the quality of products.
