Insulation Glass Fiber Reinforced Plastic Gfrp Water Blocking Yarn for Optical Cable

Product Description

Glass wire water blocking material is a new type of waterproof material made of glass fiber as the main raw material and through high temperature heated pressure after adding special chemicals.

Product Description
Generally, the cable is laid underground in the wet area, and when the cable is damaged, the water will enter into the cable from the damaged point.For copper cables, water reduces signal strength because the capacitance changes; For optical cable, if the water is frozen in the cable, it will cause too much pressure on the optical element, which can greatly affect the transmission of light.General requirements for water-blocking yarn has higher tensile strength, longitudinal elongation, long-term heat stability, instantaneous thermal stability, expansion rate and height, lower surface resistance and volume resistance characteristics.
Water blocking yarn can block water because of containing absorbent resin component, when the water into the cable, it can quickly put the water absorption, and through the expansion effect, blocking the water from the damaged point and cavity closed immediately, water cannot penetrate further. Water blocking type cable is essential for water-blocking cable material, absorbing water quickly, high expansion ratio, and the advantages of resistance to tension stress, can instead of the commonly used ribbon and ointment or water-blocking tape, especially for pipeline, directly buried cable and the cable in water can provide more full and lasting protection, it is one of the best materials cable internal longitudinal resistance of water.In recent years, with the slow growth production of China's fiber optic and cable , the growth rate of the water retardant yarn industry has also been slowing down.

Product Features
1. Good air permeability: one of the characteristics of glass waterproof material is good air permeability, which is because glass waterproof material can achieve waterproof effect through air, at the same time, air permeability can also help accelerate the drying speed inside the building.
2. Good temperature resistance: glass wire waterproof material in high temperature and low temperature environment have good tolerance.
3. Corrosion resistance: glass wire waterproof material can effectively resist the influence of acid, alkali and other corrosive substances, and reduce its damage to the building structure.
4.Long life: glass wire waterproof material has a long life, can last for more than 10 years.
The role of glass wire waterproof mainly has the following aspects:
1.Prevent water penetration: glass wire waterproof material can prevent water penetration, so that the building structure is not subject to water erosion, so as to ensure the stability of the building.
2.Prevent corrosion: the glass wire waterproof material can effectively prevent the building structure from being affected by corrosive substances, and prolong the service life of the building.
3. Improve the quality of buildings: glass and wire waterproof materials have a very high role in the protection of buildings.
Application
waterproof yarn widely used in the building roof, wall, basement and pool and other places. In addition, glass wire waterproof materials can also be used in factories, workshops, municipal roads and other waterproof projects.
