The insulation flexible duct is the ventilation pipeline of concentrate cooling and heating. It is integrated by the grassroots, heat -blocking thermal insulation layers, protective layers, and thermal reflex layers , which has changed the traditional on -site manual operation. And it has some advantages, such as reliable, good thermal insulation performance and waterproof, moisture -proof, anti -corrosion and sealing performance.
In addition to the advantages of good stiffness and strong intensity , the insulation flexible duct has the performance of secondary insulation, sound absorption and noise reduction. The appearance of the insulation flexible duct is an aluminum foil, which overcomes the fatal weakness of the previous glass fiber air duct ,such as susceptible to damaging the outer wall, and it promotes the advantages of aluminum foil. The next layer who is close to aluminum foil is high -quality fiberglass wool, retaining the advantages of sound absorption and noise reduction
Now let's talk about the composition and specification of insulation flexible duct in detail
First, material: aluminum foil+heat -thermal fiberglass cotton+glass fiber cloth
Second, specification :
1. SIZE: R6 & R8
2. Thickness: 0.5mm
3. TEMPERATURE: -30Degree to 150Degree
4. Wire: 0.8 ~ 2mm
5. Flow velocity; 28m/s
Third, adbantages:
1. The outermost layer is aluminum foil, a layer of thermal glass fiber cotton in the middle, and then bonding a layer of glass fiber cloth, which is supported by spiral steel wire
2. High telescopic, good bending, easy construction
3. Compared with life, the current insulation flexible duct is longer than traditional insulation duct, and the appearance is beauty.
4. fiberglass wool is a fiber structure, which has low thermal conductivity and good thermal insulation
5. The glass wool plate with open -hole structure can absorb sound waves and reduce environmental noise
6. No need to add other thermal insulation materials , which save space and save costs
