According to the standard, seat belts and safety ropes should use nylon, vinylon, and silk materials, and metal fittings should use ordinary carbon steel. In fact, due to the low strength of vinylon materials, they are used less and less in actual production. The strength of silk material is similar to that of nylon. It has good heat resistance and light specific gravity. It is a good material for making seat belts, but it is expensive and seldom used except in special places. With the continuous development of science and technology, the research and development of new technologies and new products, some new materials with high strength, light weight and better comfort are used in the production of safety belts and safety ropes. These materials should not be excluded from safety. Outside of production. In addition, when selecting raw materials, producers should pay attention to identifying high-strength yarns and polypropylene yarns. Polypropylene fiber is not resistant to aging and is a material that is prohibited by the state from being used in the production of safety belts. If polypropylene is used in the production of safety belts, it will pose a great threat to the lives of the users. Because polypropylene filaments and high-strength filaments are very similar in appearance, it is difficult for non-professionals to identify them. Manufacturers should pay special attention to them when purchasing raw materials. When the authenticity cannot be identified, it should be sent to the relevant department for inspection, and it can be used only after passing the inspection. Users of seat belts should also increase their self-protection awareness, pay attention to identifying the materials of the seat belts when purchasing, and ask for relevant certificates from the manufacturer. Avoid using it when you cannot confirm it. The safety belt standard expressly stipulates that the use of welded semicircular rings, triangle rings, figure-eight rings, pin-shaped rings, and circular rings is not allowed. However, in order to reduce production costs, some companies still use welded parts to assemble seat belts, and some users have not paid enough attention to this problem. There is a great hidden danger of insecurity. The welding process itself is an ancient production process. The welding quality is good, and the strength of the weld joint will not be lower than that of other parts of the accessory; if the welding quality is not good, the metal part will be disconnected from the weld joint first when the force is applied. Companies that produce welded parts are mostly informal manufacturers with low technology, poor processing capabilities, and quality cannot be guaranteed. It is very dangerous to use such parts to assemble seat belts. In the event of a fall accident, casualties are inevitable. Therefore, both producers, sellers and users should pay enough attention to this issue and control the quality of each.
