PP-R管材目前是我国塑料管材应用较好的一个品种,据北京塑料工业协会的统计,我国2002年在室内冷热水管道中PP-R管材的销量达到2.5亿m(约相当于2.85万t),是国内新型塑料管道中用量最大的品种(2002年铝塑复合管销售量1亿m,交联聚乙烯管0.7亿m)。已是2002年欧洲20国PP-R管材用量6.48千万m的3倍,并已接近全球PP-R用量6万t/a的50%。在北京市建委备案的PP-R管材生产企业达到300家,在浙江诸暨地区最少有500家工厂在生产类似的产品。总之,我国PP-R管材的生产已经有了相当的规模,整体上处于严重的供大于求的状态。但在PP-R管材的应用和生产上还有一些误区,这些直接影响到PP-R管材市场正常健康的发展,而培育一个良好的国内市场则是众多国内PP-R生产企业生死悠关的头等大事。
According to the statistics of Beijing Plastics Industry Association, the sales volume of PP-R pipes in domestic hot and cold water pipes in 2002 reached 250 million m (equivalent to about 28,500 t) is the largest new type of plastic pipe in China (2002, sales of aluminum-plastic composite pipe 100 million m, cross-linked polyethylene pipe 70 million m). It is three times of 6.48 million m PP-R pipe used by 20 European countries in 2002 and is close to 50% of the global PP-R consumption of 60,000 t / a. The PP-R pipe manufacturer filed with the Beijing Municipal Construction Commission has reached 300, and at least 500 factories in Zhuji, Zhejiang, are producing similar products. In short, China PP-R pipe production has been a considerable scale, as a whole is in a state of oversupply. However, PP-R pipe application and production there are some errors, which directly affect the PP-R pipe market normal and healthy development, and to cultivate a good domestic market is the life and death of many domestic PP-R manufacturing enterprises Top priority.
