硬聚氯乙烯建筑塑料大有发展前途首先,广大的建筑市场为发展硬聚氯乙烯建筑塑料提供了巨大的机能性。据建设部预计,到2000年,全国新增城市150个,新建集镇3000个左右;新增城市上水管普及率达95%;城市新增燃气管道、集中供热新增的建筑面积、还有邮电通讯的增长,都要求硬聚氯乙烯建筑塑料有相应的增长。另外,“九五”期间,全国村镇建设住宅将达7.5亿平方米。合计起来,每年工业和民用建筑面积将不少于12亿平方米。如此巨大的建筑市场,在今后一段相当长的时期内,将保持其发展势头。其次,我国已有一批相当规模的建筑塑料厂,有近200条进口双螺杆生产线,有些企业从事建筑塑料生产已达10年以上。
Hard PVC building plastics have great development prospects First of all, the vast construction market has provided tremendous functionalities for the development of hard PVC plastics. According to the Ministry of Construction’s estimation, by the year 2000, 150 new cities will be added nationwide, and 3,000 new towns will be newly built; the penetration rate of new urban water pipes will reach 95%; new gas pipelines for urban areas, new heating area for centralized heating, and The growth of post and telecommunications requires a corresponding increase in the use of PVC plastics. In addition, during the “Ninth Five-Year Plan” period, the total number of residential buildings in villages and towns will reach 750 million square meters. Taken together, the annual industrial and civil construction area will be no less than 1.2 billion square meters. Such a huge construction market will maintain its development momentum for a long time to come. Secondly, China has a number of large-scale construction plastics plants. There are nearly 200 imported twin-screw production lines. Some companies have been engaged in building plastics production for more than 10 years.
