Background introduction
Optical fiber non-woven tape has a variety of important roles in optical fiber manufacturing and application, including heat preservation, fire prevention, moisture-proof, anti-corrosion and so on. It is mainly used in water cables and fire-resistant optical cables that require water resistance and fire protection performance.
Main role
1) Thermal insulation: optical fiber non-woven tape can effectively reduce the energy loss of optical fiber and heat loss, so as to improve the transmission efficiency and energy saving effect of optical fiber.
2) Fire protection: As a fireproof material, optical fiber non-woven tape can effectively slow the spread of fire, and to a certain extent reduce the harmful gases and toxic smoke generated by optical fiber, protect the safety of optical fiber and its surrounding environment.
3) Moisture resistance: fiber optic cable non-woven tape can effectively prevent the fiber optic cable from being invaded by water vapor, rain and fog, especially in the long-term outdoor environment of the fiber optic cable, this moisture resistance is essential to improve the service life of the fiber optic cable.
4) Anti-corrosion effect: optical fiber non-woven tape can effectively prevent corrosion of optical fiber in the process of long-term use, reduce maintenance costs, while enhancing the structural strength of optical fiber, improve the mechanical properties of optical fiber.
Summarize
In addition, optical fiber non-woven tapes also have high strength, good high temperature resistance (can be used in 150℃ environment for a long time), aging resistance and ultraviolet resistance, high elongation, stability and good permeability, corrosion resistance, sound insulation, anti-mothproof, non-toxic and other advantages, these characteristics make non-woven tapes become the global optical fiber industry's conventional coating materials. In the optical cable manufacturing process, the non-woven material is usually used for the internal insulation layer of the optical cable or the external sheath coating, and its good thermal insulation performance, mechanical strength and good water resistance also have a corresponding role in the extension of the life of the optical cable.
