With the development of modern agricultural technology, the demand for efficient and environmentally friendly irrigation systems in horticulture is increasing. However, in actual operation, pesticide chemicals will inevitably affect the components of the irrigation system, especially the polymer hose materials used for water delivery. In order to ensure that polymer hoses can work stably and for a long time without corrosion, the selection and treatment of polymer materials become particularly important.
1. Selection of polymer materials
Selecting suitable polymer materials is the first step to ensure the corrosion resistance of polymer hoses. Polymers such as polyethylene (PE), polypropylene (PP) and polyvinyl chloride (PVC) are widely used in the manufacture of agricultural irrigation polymer hoses due to their excellent chemical stability and corrosion resistance. These materials have good resistance to a variety of acids, alkalis and salts, so that they can maintain structural integrity in environments containing pesticide chemicals.
2. Material modification and enhancement
In order to further improve the chemical resistance of polymer hoses, additives such as antioxidants and UV stabilizers can be added to improve the physical and chemical properties of the polymer matrix. In addition, the mechanical strength and chemical corrosion resistance of polymer hose can be effectively improved by combining different types of polymers by blending or compounding technology.
3. Surface treatment and coating
In addition to improving the material itself, surface treatment is also one of the key measures to improve the corrosion resistance of polymer hose. By coating the surface with a protective film with special functions, such as fluorocarbon coating or epoxy resin, an effective barrier can be formed to prevent pesticide chemicals from directly contacting the polymer material inside the polymer hose, thereby extending its service life.
4. Experimental verification and evaluation
Finally, any newly developed or improved polymer hose product should undergo rigorous laboratory testing and field trials to evaluate its performance under specific conditions. This includes simulating different usage scenarios, testing the durability of polymer hose when exposed to various types of pesticides, and making necessary adjustments and optimizations based on the results.
In summary, by carefully selecting suitable polymer materials, combining advanced material modification technology and effective surface treatment methods, the corrosion resistance and long-term stability of polymer hose in horticultural pesticide contact environments can be significantly improved, providing modern horticulture with more reliable and efficient irrigation solutions.
