Product Name: Steel fireproof smoke curtain (side type)

Product Introduction:

Ordinary side fire curtain is mainly made of LF24 type curtain, the material used is double layer δ=0.8mm high quality electrolytic zinc plate filled with aluminum silicate fiber cotton composite after surface spray treatment or with double layer δ=0.8mm stainless steel plate composite, suitable for fire resistance grade ≥3 hours in all kinds of buildings fire partition. ◆ Super lateral fire curtain is according to GB50045-95 "High-rise civil building design fire Code" emphasizes: "In the place where the firewall is really difficult to set, fire curtain can be used for fire partition." When the fire protection roller curtain including the temperature rise of the back fire surface is used as the fire resistance limit determination condition, the fire resistance limit is not less than 3.00h; When a fireproof rolling curtain is used that does not include the temperature rise of the back fire surface as the fire resistance limit determination condition, both sides of the rolling curtain shall be protected by independent closed automatic sprinkler system, and the sprinkler duration of the system shall not be less than 3.00h." Products developed under such requirements. The production of the product is to add a water curtain spray system on the basis of the LF24 type ordinary side-fire rolling curtain, and the surface of the LF24 type curtain sheet is specially treated. When the control system receives the fire alarm signal, and the rolling curtain is completely closed, the electromagnetic valve of the spray system is opened, so that the surface of the entire curtain surface forms a layer of uniform and flowing water curtain, constantly taking the heat away. Effectively control the temperature rise of the curtain, greatly improve the fire resistance of the curtain. It is the ideal product to replace the firewall, which is suitable for the partition partition of the fire rating of the building and the place with high wind pressure resistance.

The above products are mainly used in the places where the internal fire partition of the buildings is more complex, such as with the Angle (R≥400mm), the opening span is large (unilateral ≤50m, double axis ≤100m, greater than this value can refer to the design), the space height (≤6m greater than this value can refer to the design) is not suitable for the installation of vertical rolling curtains and other places; When the guide rail is equipped (according to customer needs), its mechanical properties are better, with wind pressure resistance, high strength and other properties, so it has the anti-theft function; Simple and convenient to use, can realize the linkage control of the fire control center, can also be an independent unit, by the smoke, temperature detector to provide signals and separate opening and closing, and both automatic and manual opening and closing function.
