The anti-aging advantage of polyester lanyard enables it to show good stability in a variety of environments, and to further delay its performance decline, it is necessary to start from multiple aspects.
First of all, from the perspective of storage environment, polyester lanyard should be stored in a dry, well-ventilated and temperature-appropriate place. A humid environment easily causes polyester fibers to absorb moisture, which will cause the material to expand or hydrolyze, thereby affecting its performance. For example, in some coastal areas, the air humidity is high. If the lanyard is placed randomly, it may change in size and decrease in strength due to moisture absorption. A dry environment can effectively avoid this situation. At the same time, good ventilation can prevent the lanyard from breeding microorganisms such as mold due to long-term confined space. These microorganisms may decompose the organic components of the lanyard and accelerate its aging. Suitable temperature is also very important. Excessive temperature will accelerate the movement of polyester molecular chains, prompt oxygen molecules to react with polyester molecules, lead to oxidation of the material, make the lanyard brittle and lose elasticity.
Secondly, during use, avoid exposing polyester lanyard to sunlight for a long time. Ultraviolet rays are one of the main factors that cause polymer materials to age. When exposed to sunlight for a long time, ultraviolet rays will destroy the chemical bonds in polyester molecules, causing the molecular chains to break, which will cause the surface color of the lanyard to turn yellow, become brittle, and lose its luster. For example, some polyester lanyards used outdoors will show obvious signs of aging after a period of sun exposure if proper protective measures are not taken. Therefore, when used outdoors, the lanyard can be equipped with a sunshade or placed in a sheltered place to reduce direct exposure to ultraviolet rays.
In addition, care should be taken to avoid contact between polyester lanyard and chemicals. Although polyester has good resistance to most chemicals, some strong acids, strong alkalis and other chemicals may corrode it. For example, in some industrial production environments, there may be various chemical reagents. If the lanyard is accidentally exposed to these reagents, chemical reactions may occur, causing the surface of the lanyard to be corroded, cracked or brittle, thereby affecting its performance and service life. Therefore, when using the lanyard, make sure it is away from these chemicals.
In addition, the correct use method can also delay the performance degradation of polyester lanyard. Avoid subjecting the lanyard to a load that exceeds its rated tensile force. Excessive stretching may cause changes in the molecular structure of the lanyard, reducing its strength and wear resistance. At the same time, try to minimize the twisting of the lanyard, because twisting will cause uneven stress distribution inside the lanyard, and local areas are prone to wear and fatigue damage. For example, when hanging items, ensure that the lanyard is evenly stressed to avoid excessive local stress.
Regular inspection and maintenance of the polyester lanyard is also very important. Before and after use, carefully check the lanyard for wear, cracks, deformation, etc. If the lanyard is found to be severely damaged, such as cracks or partial breaks, the damaged part or the entire lanyard should be replaced in time. In addition, clean the lanyard regularly to remove impurities such as dust and oil on the surface, which may react chemically with other substances in the environment or increase the degree of wear of the lanyard.
You can also consider surface treatment of the polyester lanyard. For example, special protective coatings can be used. These coatings can contain ingredients such as UV inhibitors, lubricants and preservatives. Anti-ultraviolet agents can effectively absorb and reflect ultraviolet rays, reducing the aging effect of ultraviolet rays on the lanyard; lubricants can further reduce the friction coefficient of the lanyard surface and enhance its wear resistance; preservatives can resist chemical corrosion in harsh environments.
Finally, operators should receive relevant training and be familiar with the use specifications and precautions of polyester lanyard. Understand the load parameters, temperature limits and other requirements of the lanyard, and strictly follow the specifications during use to avoid accelerated aging and performance degradation of the lanyard due to improper operation.
