Shop by curtain plate rolling gates, rail, transmission, rolling door motor and electrical control systems and other components, with innovative design, beautiful appearance, compact structure, wind, fire, smoke, flexible opening and closing, smoke, temperature sense detector and fire alarm system linkage, the case of the fire can be achieved when the automatic control. shop roll gates for various industrial and civil buildings fire district, the case of a fire, you can cut and prevent flame spread and reduce losses, fight fire rescue time. Products according tostandard production, the national fixed fire extinguishing systems and fire Component Quality Supervision and Inspection Center to test its technical performance has reached national advanced level of similar products.
Technical performance 1, according to judgment, refractory time 180 minutes or more, completeness undamaged;
2, according to , measured at a distance of 3 m pieces of radiant heat is measured at 0.53W / m
3, the strength test, resistance to wind pressure 120 curtain plate B = 3m, midspan deflection ≤ 60mm
4, according to , opening and closing speed 2.5 - 6.5m/min
Injury, brush roll scrap and cause considerable damage, while using the brush roll will never completely scrapped phenomenon. (4) The grinding brush roll (commonly known as carbon fiber sanding rolls) imported from Germany abrasive wire brush plate can be quickly replaced, when sanding abrasive filaments were flexible contact with the fabric, grinding force, the role of soft, fabric sanding roll hair short and uniform, delicate and soft, fabric strength decreased slightly, difficult to produce a common sand paper roller stripes, a bump on the surface texture of the fabric is unique.
The grinding roller adopts advanced flocking technology, good stability, do not shed, no deformation, high strength, good balance, completely avoid the traditional brush roller mill problems arising.
The brush roll has been used for more than one Rafah sanding machine, the effect is quite good
