What are the precautions for material selection of adjustable micro sprinkler

As an important equipment for agricultural irrigation, the selection of materials for adjustable micro sprinklers is crucial to ensure their performance and durability. During the design and manufacturing process, special attention should be paid to the following points. 
First, corrosion resistance is an important consideration. There are many corrosive substances in the agricultural irrigation environment, such as chemical fertilizers and pesticides, so the material of the adjustable micro sprinkler needs to have good corrosion resistance to prevent corrosion and performance degradation or damage. Commonly used corrosion-resistant materials include stainless steel, plastics (such as polyethylene, polyvinyl chloride) and chemical corrosion-resistant alloys. When selecting materials, it is necessary to determine the most suitable material according to the specific irrigation environment. 
Secondly, high temperature resistance is also a factor to be considered. Agricultural irrigation is usually carried out in a high temperature environment, especially in summer. Therefore, the material of the adjustable micro sprinkler needs to have good high temperature resistance to ensure normal operation in a high temperature environment. Some plastic materials, such as polyethylene and polypropylene, have good high temperature resistance and can be used for a long time in a high temperature environment. In addition, some special alloy materials can also provide high high temperature resistance. 
Third, resistance to ultraviolet radiation is also an important factor to be considered. Agricultural irrigation equipment is usually exposed to outdoor environments, and long-term exposure to ultraviolet rays will cause material aging and performance degradation. Therefore, the material of the adjustable micro sprinkler needs to have good resistance to UV radiation. Some special plastic materials, such as polyethylene and polypropylene, have good resistance to UV radiation and can be used for a long time in outdoor environments without being affected by UV rays. 
Fourth, strength and wear resistance are important factors to consider when manufacturing adjustable micro sprinklers. Agricultural irrigation equipment usually needs to withstand greater pressure and wear, especially when used for a long time and frequently adjusting the position of the sprinkler. Therefore, the material of the adjustable micro sprinkler needs to have sufficient strength and wear resistance to ensure that it will not deform or damage under pressure and wear. Some materials with higher strength, such as stainless steel and wear-resistant plastics, are often selected to manufacture key components of the sprinkler. 
Finally, for some special agricultural irrigation applications, such as irrigation of vegetables and fruits, the material of the adjustable micro sprinkler needs to meet food grade standards. This means that the material needs to be non-toxic, tasteless, odorless, and will not have a negative impact on crops and human health. Common food-grade materials include food-grade plastics (such as polyethylene, polypropylene), stainless steel, etc. In this special application, it is very important to choose materials that meet food-grade standards.
