Brief introduction of PE farmland irrigation pipe

PE is polyethylene plastic, the most basic kind of plastic, plastic bags, cling film, etc. are PE, HDPE is a highly crystalline, non-polar thermoplastic resin. The appearance of the original HDPE is milky white, and it is translucent to a certain extent in the thin section. PE farm irrigation pipes must withstand a certain pressure, and usually PE resins with large molecular weight and good mechanical properties, such as HDPE resins, are used. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, and is not suitable as a material for water pressure pipes. However, due to its high sanitary indicators, PE, especially HDPE resin, has become a common material for the production of drinking water pipes. HDPE resin has a small melt viscosity, good fluidity, and easy processing, so the range of choice of its melt index is also wide, usually MI is between 0.3-3g / 10min.

PE farm irrigation pipes need to work in a low temperature environment. The low-temperature brittleness temperature of polyethylene is extremely low, and it can be safely used in the temperature range of -60-60 ° C. During construction in winter, due to the good impact resistance of the material, the pipe will not be brittle. At the same time, resistance to stress cracking is good, and the effect of temperature changes is small.

PE farm irrigation pipes can withstand the corrosion of a variety of chemical media, and the chemicals in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator, so it does not rot, rust, or electrochemically corrode; it also does not promote the growth of algae, bacteria, or fungi.

PE farmland irrigation pipes have a long service life. Polyethylene pipes containing 2-2.5% uniformly distributed carbon black can be stored or used outdoors for 50 years without being damaged by ultraviolet radiation.

To sum up, PE irrigation pipe is an excellent choice for agricultural pipes.
