Problems solved by technology

However, at present, the main physical indicators for evaluating the quality and safety of high-strength polyethylene monofilaments for fishing or polyethylene monofilaments for fishing are diameter, linear density, breaking strength, elongation at break and single-thread knot strength, GB10023-1988 "Fishing The standard for polyethylene monofilament only includes the test methods for the above four indicators, and there is no test method for the abrasion resistance of polyethylene monofilament for fishing.

Embodiment Construction

[0006] In order to prevent and avoid the deviation of the polyethylene monofilament wear resistance test results and obtain accurate evaluation results, when explaining the specific test method, implement the present invention according to the experimental conditions, experimental methods and data processing instructions that affect the wear resistance test results The best way:

[0007] Experimental conditions

[0008] The friction and wear and tensile mechanical performance tests are all carried out in the laboratory environment, the laboratory temperature is (20±1)°C, and the relative humidity is (65±5)%; the sample is balanced in the laboratory for more than 12 hours; the wear resistance test It is carried out under two conditions of dry friction and water lubrication. When tap water is used as the lubricating medium, it is dripped at the contact surface of the wear body at a rate of 65-70 drops / min; after a certain period of friction and wear test, the wear body -60 # Sa...

Abstract

A method for testing abrasion resistance of fishing high strength polyethylene single tread includes tying one end of thread on ring of tester and another end on weight through pulley and sand wheel, contact single thread surface closely on wearing body, obtaining rub frequency when thread is broken, using ratio of break rubbing frequency to tread density as thread abrasion resistance, wearing thread for certain time then using break strength ratio and break tensile variation D-value before and after thread wear-out to obtain strength hold rate and tensile variation of thread.

Description

technical field [0001] The invention relates to a method for testing the physical properties of monofilament for fishing. Background technique [0002] Fishing high-strength polyethylene monofilament has the advantages of high strength, light weight, and high cost performance compared with ordinary polyethylene monofilament. It is widely used in bottom trawls, sail nets, net cages and sea anchors for squid fishing boats. Rope and other fishery production fields. For the materials of net gear, mechanical wear is one of the main reasons for reducing the strength and service life of the net gear, and causing the deformation of the net gear. From the perspective of use and economy, it is very important that the fishing gear material has the ability to resist abrasion. With the continuous expansion of the application field of high-strength polyethylene monofilament for fishing, it is urgent to understand the performance of polyethylene monofilament materials against mechanical w...
