One is to look at. Look at the product appearance, usually good quality ropes and nets look from the appearance, uniform thickness, color pure, smooth and brightness. And inferior product color is not pure, uneven thickness, mixed with reworked material product color gray, even abnormal smell. Then look at the product label, large scale, good quality of normal manufacturer production net fishing tackle products have the producer name and address and factory inspection certificate, etc, have executed standard code, even comes with a copy of inspection report, the product quality are guaranteed. Instead provide the relevant information is hard to ensure the quality of the products. Open for fishing nets, mesh look have obvious K type, are there any appreciable size line, if there is any leakage of mesh, so as to judge the quality of network.
2 measure strain. Our products main inspection items for breaking strength, with a tensile testing machine to get accurate data. As a general consumer, inspection pull the simplest way is to take out a monofilament, snap it with both hands, according to the size of the force, monofilament is not easy to break the nets are of good quality, monofilament gently pull it off the nets quality is poor. With farmar monofilament hoisting test inspection or the quality of the cable, it's also a good way. For our products also can use finger to pull a pull, tensile strength of the mesh, so as to judge the quality of network.
Three touch by hand. Most of polyethylene net fishing tackle products, in addition to the special requirements, general with soft as well. Touch the, so as to choose good product.
Four selected manufacturers. For larger user demand, should be based on the usage of our products, choose the manufacturers as a supplier quality stable, directly from the manufacturer replenish onr's stock, so can enjoy preferential treatment in the factory wholesale price, and convenient for contact when have special requirements. State supervision and spot checks of qualified enterprises products can be at ease use.
Synthetic fibers are widely used in fishery, basically replaced the natural fiber, shows the unique advantages. One is the low hygroscopicity, anticorrosion and durable. Water quantity is smaller than plant fiber 1/2 ~ 1/3, some of synthetic fiber is not hygroscopic, almost made of net fishing gear can long-term immersion in water or in wet and not decay damage. The second is the proportion of small, high strength, especially the proportion of polyethylene and polypropylene fiber are less than the proportion of water, nets made of light weight, water resistance is small, convenient to operate and can improve the towing speed, increasing the amount for fishing. Third, good elasticity, impact resistance. Especially the polyamide (nylon) monofilament net at 8% elongation, elastic recovery rate is 95% ~ 100%, suitable for the production of gillnets. In addition to the above advantages, we should also see the products there are still some defects. To avoid defects, play advantage, extend the use fixed number of year of net fishing tackle products, need to pay attention to the following:
1, because of the large synthetic fibre elongation, holding force is small, made into nets, net and poor stability, must be treated with heat styling to use.
2, our products are light fastness is poor, so when the storage and use, should not be placed outdoor or in the sunlight, otherwise it will reduce the strength.
3, polyamide (nylon) nets have alkali resistant effect, but not resistant to strong acid, therefore should not be stored together with strong acid and other chemicals.
4, soft polypropylene fiber stiffness is bigger, more commonly used to make ropes, mainly used for middle-level trawl abroad and crab gill net material.
5, our product has the combustibility, so should be paid attention to during storage and use of fire prevention.
