Description

Technical Field

[0001] This invention relates to the field of cable technology, specifically to a water-blocking yarn liquid control device and method. Background Technology

[0002] The expansion ratio and expansion rate of water-blocking yarn used in communication cables and optical fibers are important indicators. The water-blocking principle of water-blocking yarn is that when the yarn fibers come into contact with water, they rapidly expand to form a large-volume gel-like substance. This gel-like substance has a strong water retention capacity, effectively preventing the growth of water trees and thus preventing further water seepage and diffusion, thereby achieving the purpose of water blocking. Cables and optical fibers are generally laid underground in damp areas. Once the cable is damaged, water can enter the cable from the damaged point.

[0003] For optical cables, if water freezes inside the cable, it will exert excessive pressure on the optical components, which will greatly affect light transmission. Therefore, the water-blocking performance of optical cables is an important performance indicator. To ensure water-blocking performance, water-blocking materials are introduced in every process of optical cable manufacturing, one of the most commonly used materials being water-blocking yarn. However, traditional water-blocking yarn has many problems in use. For example, uneven impregnation during glue application can lead to insufficient wrapping of the water-blocking yarn, affecting the waterproof effect. Excess glue residue on the surface of the water-blocking yarn can cause differences in the diameter of the cable surface, affecting the cable's specifications and aesthetic appearance. Summary of the Invention
