The aging problem has always been an issue that plastic irrigation fittings need to face. To solve it effectively, the best approach is to start from the characteristics of the product itself and address it at the root. It should be noted that the aging of plastic products is an inevitable phenomenon that cannot be completely avoided in the long run. What we can do is to slow down the aging process as much as possible.
Essentially, the aging of plastic fittings occurs because plastic molecules degrade under external factors, which causes their physical and chemical properties to deteriorate, eventually leading the product to lose its vitality. Nächste, I will explain how to slow down the aging process of plastic irrigation fittings from several aspects, including material selection, protective measures, improving irrigation water quality, preventing mechanical damage, and performing regular inspections and maintenance.
Choosing High Quality Materials
The most commonly used material for irrigation fittings is PP. It has a relatively low density and good heat resistance, allowing it to be used in high-temperature environments. Gleichzeitig, its price is relatively low, making it a cost-effective material that perfectly fits the usage scenarios of irrigation fittings.
Zusätzlich, to slow down aging, anti-UV agents and anti-aging additives can be added to the raw materials during the production process of irrigation fittings. Darüber hinaus, we must avoid using recycled or inferior materials to produce products and must use 100% new material to manufacture irrigation fittings.
Protective Measures
Direct sunlight, high temperature, and oxidation reactions are the three main culprits that cause plastic irrigation fittings to age.
The ultraviolet rays in sunlight can destroy the molecular chain structure of plastics. Prolonged exposure will cause plastic products to turn white and hard, reduce their strength, and eventually make them completely unusable. To deal with this problem, we can add anti-UV agents during the production process. Gleichzeitig, it is necessary to apply a protective film on the product surface.
We also cannot ignore the impact of high temperatures. As the temperature rises, the molecular chain structure of plastics will also change, causing the products to become hard and brittle, which shortens their service life. Especially during hot weather, we need to take cooling measures for the products.
Endlich, the oxidation issue should not be overlooked either. Oxygen reacts with many substances in the world, and plastic products are no exception. Especially under the combined effects of strong light and high temperature, oxidation reactions will intensify, leading to changes in the performance of plastic products. daher, we can cover the surface of the products with heat-insulating films and add antioxidants during production to slow down oxidation and degradation.
Zusätzlich, irrigation fittings should be stored in cool, shaded warehouses. If they must be kept outdoors, it is important to avoid direct sunlight — using a shade net to block sunlight is a good solution.
Improving Irrigation Water Quality
Irrigation fittings often come into contact with water. Im Laufe der Zeit, hydrolysis reactions can occur between water and plastic products, damaging the molecular structure of the plastic fittings and causing deformation or even cracking.
It is especially important to note that irrigation water is not the same as ordinary water. In fertigation systems, irrigation water often contains fertilizers, which means it may include chlorine, weak acids, and weak alkalis. These chemical substances can react with plastics.
Even if the water does not contain fertilizers, if the water source is polluted, it can still have an impact on the irrigation fittings.
daher, we must improve the water quality as much as possible. After fertilization, the pipes should also be flushed and cleaned promptly to avoid chemical residues remaining in the pipelines, which could affect the service life of irrigation products.
Preventing Mechanical Damage
When plastic fittings are squeezed against each other — for example, when they are being connected — mechanical stress is generated between them. This pressure can cause deformation of the irrigation fittings to some extent, changing their physical structure, which is also one of the reasons for their aging.
To avoid this problem, engineers should try to minimize the use of connectors when designing irrigation systems, as long as it does not affect the final irrigation performance. This can help reduce mechanical stress to a certain degree.
In addition to mechanical stress between products, the external environment can also cause mechanical damage. For instance, collisions during transportation, being struck by stones during installation, being stepped on, or run over by vehicles can all cause harm to the products. All these situations should be carefully avoided.
Regular Inspection and Maintenance
The aging process of plastic irrigation fittings is very slow. During long-term use, we must not forget to regularly inspect and maintain them. These products should be kept clean and free from dirt and impurities.
We also need to regularly check whether they have problems such as cracking, discoloration, hardening, or becoming brittle. If any issue is found, it must be addressed promptly.
When storing irrigation fittings, it is important to choose a dry and shaded warehouse for storage.
