Irrigation pipe manufacturers, Xiong Wang Thai (certified), Zaozhuang irrigation pipe provided by Xiong Wang Thai Plastic Products Factory. Xiong Wang Thai Plastic Products Factory (www.wangtai668.com) is specialized in the "plastic tube, MPP power tube, CPVC pipe electricity, irrigation pipes, HDPE pipes, p" of the enterprise, the company of "honesty, hard service" concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Fengjing Li. Since the 1990s, our synthetic resin industry booming, production and consumption has maintained a good momentum of growth. At present, China's synthetic resin production capacity will reach 10 million tons, after the column the United States, Japan, Germany, South Korea, the top five in the world. However, required a variety of special resin plastic pipe there is a big gap in our country, although PE and PP resin production is large, but not many suitable pipe resin, especially suitable for urban water supply, city gas distribution with PE hot and cold water pipes and construction of special PP-R Compound with fewer sales irrigation pipe, need to import a certain amount of plastic pipe special resin. Rapid development of plastic pipe, the quality has been improving. Xiong Wang Thai Plastic Products Factory PE is the most common method of producing a slurry or gas processing method, there are a few with a solution-phase processing. All these processes are derived from ethylene monomers, a- olefin monomer, the catalyst system (may be more than one compound), and various types of hydrocarbon diluent exothermic reaction participation. Some hydrogen and catalyst to control the molecular weight. The slurry is generally stirred tank reactor or a more common large loop reactor irrigation pipe specifications, in which the slurry can be recycled stirring. When ethylene and comonomer (if necessary) and a contact catalyst irrigation pipe, polyethylene particles will form. After removal of the diluent irrigation pipe manufacturers, polyethylene granules or powder is dried and press the additive dose, it produced pellets. Large reactors with a twin-screw extruder modern production lines, production PE40000 pounds or more per hour. Development of new catalysts for the improved performance of the new grade HDPE contribute. The two most common types of catalysts of the chromium oxide catalyst is Philip compound an alkyl aluminum and titanium-based catalyst. Phillips catalyst produced HDPE has a molecular weight distribution width; titanium aluminum alkyl catalyst for the production of a narrow molecular weight distribution. Production of narrow MDW dual reactor polymer catalyst used can also be used to produce a wide MDW grade. For example, the production of two reactors in series significantly different molecular weight products can produce a bimodal molecular weight polymer, the polymer having a molecular weight distribution of the full width of the domain.
