PE Lay Flat Hose Polymerization Conditions
PE Lay Flat Hose Polymerization conditions
PE hose is made of monomer ethylene polymerization, due to the polymerization due to pressure, temperature and other polymerization conditions are different, can be obtained different density of resin, pe hose is one of them. 3, low energy consumption, low input, low irrigation Cost, high standard water saving and high efficiency; 4, pipeline water and field water-saving technology combined. Applicable conditions: suitable for all types of irrigation field field irrigation performance, specifications 1, diameter: 63 mm 75mm 90mm 2, wall thickness: 0.15,0.20,0.25,0.30,0.35,0.40mm 3, working pressure: 30 ~ 600Kpa applicable Scope and characteristics: 1, widely used in urban and rural water supply and drainage works. 2, good resistance to wear, non-toxic, anti-ultraviolet, good flexibility. 3, add anti-aging agent, long life, corrosion resistance.
4, to adapt to a variety of terrain, climate change. PE pipe, a good pipe, not only should have a good economy, and should have a stable and reliable interface, material impact resistance, anti-cracking, anti-aging, corrosion and a series of advantages, compared with traditional pipe, HDPE pipe system Has the following advantages: ⑴ reliable connection: polyethylene pipe system between the use of electric hot melt connection, the joint strength is higher than the pipe body strength. ⑵ low temperature impact resistance: polyethylene low temperature embrittlement temperature is very low, in the -60-60 ℃ temperature range of safe use. Winter construction, due to good impact resistance of the material, will not occur tube embrittlement. ⑶ good resistance to stress cracking: HDPE has a low gap sensitivity, high shear strength and excellent scratch resistance, resistance to environmental stress cracking performance is also very prominent. ⑷ good chemical resistance: HDPE pipe can withstand a variety of chemical media corrosion, the soil of the chemical substances will not cause any degradation of the pipeline. Polyethylene is an electrical insulator and therefore does not degrade, rust or electrochemical corrosion; it does not promote algae, bacteria or fungi. ⑸ resistant to aging, long service life: containing 2.5.5% of the uniform distribution of carbon black polyethylene pipe can be stored in outdoor open or use for 50 years, will not be damaged by UV radiation. ⑹ good wear resistance: HDPE pipe and steel pipe wear resistance comparison test shows that HDPE pipe wear resistance of steel pipe 4 times. In the field of mud transport, compared with steel, HDPE pipe has better wear resistance, which means that HDPE pipe has a longer life and better economy. ⑺ flexible: HDPE pipe flexibility makes it easy to bend, the project can change the direction of the pipeline to bypass the obstacles, in many cases, the flexibility of the pipe can reduce the amount of pipe and reduce the installation costs. ⑻ low flow resistance: HDPE pipe has a smooth inner surface, the Manning coefficient of 0.009. Smooth performance and non-sticking properties ensure that HDPE pipes have a higher transmission capacity than traditional tubing, while also reducing piping pressure loss and water consumption. Is made of monomer ethylene polymerization, due to the polymerization due to pressure, temperature and other polymerization conditions are different, can be obtained different density of resin, pe hose is one of them. PE pipe

2, the field of water and field irrigation control system set into one;
3, low energy consumption, low input, low irrigation cost, high standard water saving and high efficiency;
4, pipeline water and field water-saving technology combined.
Suitable for field irrigation of various types of irrigation
