SPLEND-30A Is a fire protection system of air ducts with fire-resistance rating EI30 (Fire Safety Certificate № SSPB.RU.OP034.V.00285 on 18.06.2008)
A comprehensive fire protection system SPLEND -30A includes: - High adhesive compound of NATRSIL-541 (TU 2316-012-29346883-2007), which is the composition of the inorganic binder and mineral fillers, dry film thickness 0.7 mm, flow rate 1.62 kg / m 2.
- Insulating nonwoven foil ISOLIR 1000F (TU 5763-055-00204961-00), 5 mm thickness.
Recommended consumption of materials
for 1 m2 insulated surface with allowance for losses | | NATRSIL-C 541 kg | ISOLIR-1000F, m2 | | 1,78 | 1,1 |
The total thickness of the coating - 6 ± 1 mm. Installation of fire-retardant coating (performed by TI 017-2008): - Prepare the surface of the duct: clean, dedust, degrease and dry.
- Thoroughly mix of NATRSIL-541 by any manual machine tool until smooth.
- Apply NATRSIL-541 to the prepared surface of the duct, using plastering machine such as SB-150, spatula or brush.
- Paste on the wet layer the thermal insulating ISOLIR 1000F foil (cut to size of duct) with surface outward. Edge of the material assembled lapped a minimum width of 100 mm with the application of NATRSIL-541 between the layers.
- To press hard a foil leaf ISOLIR 1000F and stitch with rubber roller. If necessary, tape seams with aluminum tape.
Finishing SPLEMD-30A on the flange connection of duct performs according to scheme, blades overlap should be not less than 100 mm.
When installing the fire-retardant coating on ducts close to walls, ceilings and other barriers it is allowed to fill the gap between the duct and wall by foil ISOLIR 1000F or materials based on basalt fiber (wool, felt, mats, plates), then glue on the top ISOLIR 1000F to give the design aesthetic appearance.
The scheme of covering the flange of the duct with SPLEND-30A.  Packing:
Composition NATRSIL-541 comes in plastic packaging capacity of 20 liters.
Linens ISOLIR 1000F comes packed in polythene rolls 26X1, 17m. |
