Description

Technical Field

[0001] The present invention relates to the technical field of water-blocking tape testing, and in particular to a water-blocking tape testing system and a testing method. Background Art

[0002] With the development of the times, cables occupy an increasingly important position in people's lives. In humid areas, if the sheath is damaged, moisture in the environment can easily penetrate into the cable. The water-blocking tape can effectively prevent moisture from penetrating along the longitudinal direction of the cable due to its characteristic of rapidly expanding in rainwater to form a gel-like substance, thereby ensuring the dryness of the cable. However, due to problems such as the poor storage environment and usage habits of the water-blocking tape, the waterproof ability of the water-blocking tape is greatly reduced, which requires the water-blocking tape to have a certain ability to resist the external environment at the beginning of production, so as to reduce the incidence of the problem of reduced waterproof ability of the water-blocking tape. Therefore, it is necessary to study a testing technology after the production of the water-blocking tape.

[0003] Prior art, such as the invention patent application with announcement number: CN115993427B, discloses a water-blocking tape testing device, system and testing method, the method comprising: a cup unit, comprising a main body and a fixing rod arranged in the main body, the fixing rod being arranged along the axial direction of the main body, the main body comprising a first cup body and a second cup body connected to each other, the diameter of the second cup body being larger than the diameter of the first cup body, during testing, the water-blocking tape to be tested is placed in the second cup body; a pressure plate, which is provided with a first through hole, the pressure plate is arranged on the fixing rod through the first through hole, and the pressure plate is also provided with a plurality of injection holes. The water-blocking tape testing device of the present invention can provide space for the horizontal expansion of the water-blocking tape, can reflect the actual situation of the hydrogel in the water-blocking tape expanding in the horizontal direction and the height direction when encountering water, obtain relatively accurate test results, and thus accurately judge the water-blocking performance of the water-blocking tape.

[0004] It can be seen from the above scheme that the current water-blocking tape testing technology, on the one hand, in actual applications, the water-blocking tape is prone to physical structure damage during use and storage due to poor storage environment and bad usage habits. The existing technology lacks tensile testing and temperature change testing, resulting in the quality of the water-blocking tape under extreme use conditions cannot be guaranteed. On the other hand, there is a lack of testing of water-blocking tapes of various test lengths. During the processing of water-blocking tapes, uneven mixing of composite materials is prone to occur. At certain test lengths, this problem will lead to low water absorption efficiency and slow expansion rate of the water-blocking tape. Customers of water-blocking tape manufacturers may need to use the water-blocking tape at these lengths, and thus the water-blocking performance of the water-blocking tape cannot be guaranteed.

[0082] The water-blocking tape evaluation and processing module is used to determine whether the water-blocking tapes of this batch meet the production quality standards. If not, each abnormal test length is screened and the person in charge of the water-blocking tape quality is notified that the water-blocking tapes of this batch will have the problem of uneven mixing of composite materials at each abnormal test length.

[0083] In a specific embodiment of the present invention, the specific screening method for screening each abnormal test length is: obtaining a compliance ratio threshold from a local database, counting the number of compliance test water-blocking tapes of each test length based on each compliance test water-blocking tape of each test length, counting the number of test water-blocking tapes of each test length based on each test water-blocking tape of each test length, dividing the number of compliance test water-blocking tapes of each test length by the number of test water-blocking tapes, thereby obtaining a compliance ratio of the compliance test water-blocking tapes of each test length, comparing the compliance ratio of the compliance test water-blocking tapes of each test length with the compliance ratio threshold; if the compliance ratio of the compliance test water-blocking tape of a certain test length is less than the compliance ratio threshold, it is judged that the water-blocking tape of this batch does not meet the production quality, and the test length is marked as an abnormal test length, thereby screening each abnormal test length.

[0084] The water-blocking tape evaluation and processing module of the present invention determines whether the water-blocking tape of this batch meets the production quality requirements. If not, each abnormal test length is sent to the person in charge of the water-blocking tape quality. On the one hand, it ensures that the water-blocking tape will not have the problem of uneven mixing of the composite materials in each test length, thereby ensuring the water-blocking performance of the water-blocking tape. On the other hand, it is convenient for the person in charge of the water-blocking tape quality to judge whether each abnormal test length will threaten the actual needs of the customer based on the actual needs of the customer, thereby facilitating subsequent work.

[0085] Reference Figure 2 As shown, the second aspect of the present invention provides a water-blocking tape testing method of the water-blocking tape testing system, comprising: Step 1. Water-blocking tape selection: After the water-blocking tapes of this batch are produced and processed, each test water-blocking tape of each test length is randomly selected from this batch, and each feature point of each test water-blocking tape of each test length is selected according to a predefined feature point selection strategy, and the test graphics corresponding to each feature point of each test water-blocking tape of each test length are obtained.

[0086] Step 2. Tensile test: perform a tensile test on each test water-blocking tape of each test length, and screen each tensile potential test water-blocking tape of each test length and each tensile normal test water-blocking tape.

[0087] Step 3. Abnormal environment test: perform high and low temperature tests on each normal tension test water-blocking tape of each test length, calculate the abnormal expansion coefficient of each low-temperature expansion test water-blocking tape of each test length, evaluate the abnormal expansion coefficient of each high-temperature expansion test water-blocking tape of each test length, and screen each high-temperature expansion abnormal test water-blocking tape, each low-temperature expansion abnormal test water-blocking tape and each normal expansion test water-blocking tape of each test length.

[0088] Step 4. Durability test: perform durability test on each normal expansion test water blocking tape of each test length, and screen each abnormal durability test water blocking tape and each qualified test water blocking tape of each test length.

[0089] Step 5. Water-blocking tape evaluation and processing: Determine whether the water-blocking tape of this batch meets the production quality. If not, screen the abnormal test lengths and notify the person in charge of the water-blocking tape quality. This batch of water-blocking tape will have the problem of uneven mixing of composite materials at each abnormal test length.
