Abstract

The invention relates to a sample structure for measuring seawater permeation depth and concentration of a polymer insulating material in a deep marine environment and a using method of the sample structure, and aims to solve the problems that the measurement result of an existing method for measuring permeation depth and concentration of seawater in insulation is not accurate enough, an operation process is tedious, required equipment costs are high, and the technical doorsill is also high. The device consists of a sheet sample overlapping module 1 and an injection molding thickening module 2. The method comprises the following steps: preparing the sample structure; soaking the sample structure for a certain time in a seawater environment under a certain pressure; taking out the sample structure; grouping each two layers of sheet samples into a group; and comparing difference between qualities before and after the different groups of sheet samples are dried so as to obtain permeation depth and concentration of the seawater. The sample structure is used for measuring the seawater permeation depth and concentration of the polymer insulating material in the deep marine environment.

Description

technical field [0001] The invention relates to a sample structure for measuring the penetration depth and concentration of seawater of polymer insulating materials in deep sea environment and its application method. Background technique [0002] Large-length deep-sea photoelectric composite cables with power transmission and signal transmission functions have received extensive attention and will generate greater demand in the future. Since the insulation layer of the deep-sea photoelectric composite cable is in direct contact with seawater, the infiltration of seawater will affect the insulation performance of the insulation layer. When developing corresponding products, seawater infiltration tests must be carried out. However, how to measure the penetration depth and concentration of seawater in the insulation is very difficult. The traditional technology usually adopts the following two methods. The first method is to soak a sample of a certain thickness in high-pressu...
