How to do a good job of fishing nets and repair
Nylon, nylon, polyester, Eylon, polypropylene, polyvinyl chloride, chlorinated lycopene is through the chemical synthesis of some low-temperature, low-temperature, low-temperature, Molecular weight compounds into polymer compounds, and then through the melting, spinning, drawing and made with better physical and mechanical properties of synthetic fibers. These synthetic fibers have the characteristics of small specific gravity, fast filtration, high strength, light mesh and so on, but the synthetic fiber has the disadvantage of poor anti-sunlight performance. Such as long-term exposure to sunlight will reduce the fiber strength accordingly. According to the test, the general Eulan 625 hours after the sun, the intensity decreased by 20%, the nylon line by 900 hours after sun its intensity decreased by 40% or more. Such as cotton, linen, brown and other plant fiber fishing nets with low strength, water absorption, perishable and other shortcomings. Therefore, should be based on the characteristics of various networks to take the correct storage method.
Fish net storage, the net should be on the sludge, fish greasy and other attachments washed, and then dry, and remove the seeds were stored, so as not to damage the iron Shenzi rusty clothing.
Storage sites should be kept air circulation, no direct sunlight, for a small number of small and small fishing nets can be tied tied to the roof beam; for large and large number of fishing nets, can be stored in the ground high, well ventilated conditions Warehouse. Fishing nets can not be directly on the ground, should be bundled in the ground above 0.5 meters high wooden or on a large wooden box. However, the tung oil dyed the network should not be tied to the volume, should be scattered in a higher grid, to prevent spontaneous combustion fever.
Storage time to ground inspection. When the weather is clear, dry air, the need to open the library door window, so that air circulation; in the rainy days or high humidity air, the Treasury to be strictly closed. Each value of the rainy season or the summer season, with particular attention to the network of plant fibers and the rope rope mold, should be regularly exhibited in the sun dry. Do not fish nets and chemical fertilizers, pesticides and diesel volatile or corrosive materials such as mixed strong. At the same time pay attention to insecticide, rodent work.
During the storage or fishing process, the damaged clothing should be promptly repaired. There are two methods of patching and imputation: patch method is the main method of netting repair. (3 feet and nodules connected to the three feet) from the series, in order to make up a row of holes in the lack of the same mesh with the mesh items, in the hole below the end of the tripod. In the patch before the hole to be trimmed, so that the upper and lower holes have a three-legged, the rest was straight head (side), transverse head (dang eye) -like complement, also known as single-line compilation method, not pruning Called the heavy line compounding method.
Embedded method is to cut the hole into a square or rectangle, cut a piece of clothing with the original specifications of the original network, than the hole long, wide edge of the net purpose of a less embedded, with sewing method, the four sides and holes Edge suture together, in the case of a larger hole, with the make-up method takes too much time, generally can be embedded method.
