扬子石化公司自主研发的高性能树脂塑管聚丙烯装置的发展在其最近的工业化试生产成功。在YP -的全新管道树脂国外同类产品的性能水平，R503，将成为国内聚丙烯树脂管市场的{ldz}。

的聚丙烯具有宽分子量分布，更好的共聚单体序列分布，是非常适合的PPR管材生产，双方良好的刚性和韧性的产品，加工性能，能够满足超过63毫米到大直径管生产。试产在YP -经国家建筑材料测试中心测试的R503，达到1000小时以下的短期8760水压试验和长期热稳定性试验标准时间。

PPR管材的性能，已广泛用于各种管道系统，在各种需求迅速增长。然而，较高的原材料聚丙烯管，生产更加困难，国内品牌虽然已经开发出，但生产规模较小，大部分是难以满足需求，尤其是大直径管道PPR已更加短缺原材料，管道制造商进口原料，成本上升的基本依赖。

扬子石化聚丙烯复合管的研发，积累多年的经验，经过小的测试飞行员和大量的试点，通过新型催化剂的筛选，工艺路线的设计，工艺条件的优化，产品的机械性能测试和结构表征，产品试生产和加工应用，如设计和实验系列，掌握了树脂生产过程的所有。

目前，扬子石化20万吨聚丙烯设计能力/年，其中一些用于生产树脂，树脂后，PPR管材已稳定生产F401。为了实现顺利切换F401 - R503，扬子石化研究院在测试设备进行了F401 - R503模拟开关试验，设备的稳定运行，大小和活动，氢转移过程中发挥积极释放模式，乙烯饲料，等系统测试和分析，对稳定的催化剂在产品开发使用新型首次创造更好的技术条件。调整工业化进程中，试点研究成果已在工业装置验证，以确保工业性试验的顺利进行。 YP - R503，附加值高，市场容量，其试生产成功，标志着扬子石化聚丙烯到xx市场管材料。

Yangzi Petrochemical PP pipe into the high-end market

Yangzi Petrochemical Company independent research and development of high-performance resin PPR pipe polypropylene unit at its recent successful trial production of industrialization. The YP-R503 for the brand new pipe resin performance level of similar foreign products, will become the domestic market leader in polypropylene resin pipe.

The Polypropylene has a wide molecular weight distribution, better comonomer sequence distribution, is very suitable for the production of PPR pipe, and the products of both good rigidity and toughness, processing performance, able to meet more than 63 millimeters to large-diameter pipes production. Pilot production of the YP-R503 by National Building Materials Test Center testing, reached 1000 hours the following short-term hydrostatic testing and 8760 hours of long-term thermal stability test standards.

PPR pipe performance, is already widely used in a variety of pipe systems, the rapid growth in demand. However, the polypropylene tubes on higher raw materials, production more difficult, although the domestic brands have been developed more, but most of the smaller scale of production, it is difficult to meet the demand, especially large-diameter pipe PPR is more a shortage of raw materials, pipe manufacturers the basic dependence on imported raw materials, higher costs.

Yangzi Petrochemical Polypropylene Compound Tube R & D has accumulated years of experience, after a large number of small test pilot and pilot testing, through a new type of catalyst screening, process route the design, optimization of process conditions, the product of mechanical Performance Testing and Structural Characterization, product pilot production and processing applications, such as a series of design and experiment, to master all of the resin production process.

Currently, Yangzi Petrochemical Polypropylene design capacity of 200,000 tons / year, some of which are used in resin production, after PPR pipe resin has been stable production F401. In order to realize smooth switching F401-R503, Yangzi Petrochemical Research Institute in the test device had a F401-R503 analog switch test, the stable operation of the device, active release pattern of size and activity, hydrogen transfer process, the ethylene feed, etc. a system test and analysis, the first time for a new type of catalyst stability in the use of product development to create a better technical conditions. Adjust the process of industrialization, pilot study results has been verified in industrial installations, to ensure the smooth progress of the industrial test. YP-R503 high added value, market capacity, the success of its pilot production, marking the Yangzi Petrochemical Polypropylene tube material into high-end market. (07-9-29)
