Problems solved by technology

[0005] Because the present invention simulates the situation that the high-strength polyethylene monofilament is destroyed by the ultraviolet rays in the sunlight in actual use, it is consistent with the results obtained in the atmospheric aging test of the high-strength polyethylene monofilament for fishing. The detection and quality evaluation of artificial accelerated aging of monofilament provides a concise and effective method, which makes up for the deficiency of the current fishing gear material standards. It has reasonable and reliable technical indicators and practical technical effects. Fishing gear and matching fishing materials provide a reliable basis

Embodiment Construction

[0006] Atmospheric conditions, artificial accelerated aging equipment and exposure conditions, mechanical performance test conditions of aged samples, sampling and sample processing, artificial accelerated aging test, and sample processing affect the results of artificial accelerated aging test of high-strength polyethylene monofilament for fishery. Various factors in tensile property testing, data processing and presentation of results. In order to prevent and avoid deviation, to obtain accurate assessment results, while illustrating the test method, the best way to implement the present invention is explained below with respect to various factors affecting the artificial accelerated aging test results of high-strength polyethylene monofilament for fishery:

[0007] The atmospheric conditions of the laboratory are temperature (20±2)℃, humidity (62~68)%;

[0008] The artificial accelerated aging equipment adopts ultraviolet aging test chamber, and the technical parameters of t...

Abstract

The invention relates to a polyethylene fiber monofilament accelerated ageing test method for fishing. It includes the sampling, loading and mechanical test. The feature is that: it intercepts the sample at 20m distance from one end of filament or the joint, coiling the monofilament sample on aluminum sheet that would be fixed on the sample frame of ultraviolet ageing test box; taking manual accelerated ageing test according to the cycling test process of irradiating for 8h under black standard temperature of 60deg.C and condensing for 4h under black standard temperature of 50 deg.C; after balancing for 24h in standard lab, taking mechanical test. The invention is also suitable for other compounding fiber fishing netting twine.

Description

technical field [0001] The invention relates to a detection method for an anti-aging performance index of polyethylene monofilament for fishing. Background technique [0002] Ethylene has been widely used as a fishing material. Compared with ordinary polyethylene monofilament, high-strength polyethylene monofilament has the advantages of high strength, light weight, and high performance-price ratio. In recent years, it has achieved good use in the field of fishery production. Effect. The development of cage culture, lakeside culture and pelagic fishery has put forward higher requirements for the aging resistance of high-strength polyethylene monofilaments for fisheries exposed to the atmosphere for a long time. Therefore, it is necessary to carry out high-strength polyethylene filaments for fisheries The research on aging resistance of monofilament provides a scientific basis for the design of fishing gear and the reasonable selection of materials. During the processing, s...
