Performance requirements of irrigation sprinkler knowledge

The irrigation sprinkler uses high-density polyethylene as the main raw material and is produced with advanced equipment. Under the action of a catalyst, the slurry polymerization or gas-phase polymerization process is adopted. The obtained polymer is flashed, separated, dried, and granulated. A finished product with uniform particles is obtained. Including such as sheet extrusion, film extrusion, pipe or profile extrusion, blow molding, injection molding and rotational molding.

Among all engineering plastics, HDPE has the highest abrasion resistance among plastics and is the most eye-catching. The higher the molecular weight, the more wear-resistant the material, even more than many metal materials (such as carbon steel, stainless steel, bronze, etc.). Under the conditions of strong corrosion and high wear, the service life is 4-6 times that of steel pipes and 9 times that of ordinary polyethylene; and the transmission efficiency is increased by 20%. The flame retardant and antistatic properties are good, and they all meet the standard requirements. The downhole service life is more than 20 years, the economic benefit is remarkable, the impact resistance, abrasion resistance, and the double resistance effect are remarkable. Good performance makes it very good for mining mineral resources.
The water supply pipe must bear a certain pressure, usually a PE resin with a large molecular weight and good mechanical properties, such as HDPE resin, should be used. Due to its high hygienic index, PE, especially HDPE resin, has become a common material for the production of drinking water pipes. A good pipeline should not only have good economic efficiency, but also have a series of advantages such as stable and reliable interface, anti-impact, anti-cracking, anti-aging, and anti-corrosion.
Irrigation sprinklers are the replacement products of traditional PVC and steel pipes for drinking water pipes. The water supply pipe must be able to withstand a certain pressure, usually a PE resin with good mechanical properties and a large molecular weight, such as HDPE resin; from the perspective of high temperature resistance, the performance of the PE pipe decreases rapidly as the temperature rises. The use temperature is Between ±60°, it is generally used for cold water transportation, mainly for the main road of water supply pipes. Therefore, PPR pipes will be used in the selection of water supply pipes after entering the house.
PE pipe has light weight, good toughness, high impact strength, non-toxic, cheaper price, and good low temperature resistance. It is currently the first choice for water supply and drainage pipelines such as municipal construction, real estate, factories, and water conservancy construction. Tengtong irrigation sprinklers are pollution-free, ecological, and environmentally friendly. No toxic additives are added during the production process. The inner wall of the pipe is smooth, no scaling, no bacteria breeding, and mature production, connection and construction technology. According to its physical and mechanical properties, it adopts hot-melt connection or flange connection, which has high toughness, reliable connection and convenient construction, so the safety factor is high and the pipe network leakage rate is low.
