硬聚氯乙烯塑料管的应用是建筑业“九五”期间重点推广应用10项新技术之一。这种塑料管可用于城乡供水管、室内外排水管、建筑雨水管和建筑电线套管,以部分取代钢制管道。目前这种塑料管已有升级产品,其性能比普通硬聚氯乙烯塑料管更加优异。该塑料管以聚氯乙烯为主要原料,采用两种聚氯乙烯配方3层共挤而成,其内外2层是优质硬聚氯乙烯皮层,芯层
The application of rigid PVC plastic pipe is one of the 10 new technologies that have been popularized and applied in the construction industry during the Ninth Five-Year Plan period. This type of plastic pipe can be used in urban and rural water supply pipes, indoor and outdoor drain pipes, construction rainwater pipes and building wire bushings to partially replace steel pipes. At present, this type of plastic pipe has been upgraded and its performance is more excellent than ordinary hard PVC plastic pipe. The plastic pipe uses polyvinyl chloride as the main raw material, and is made of two layers of polyvinyl chloride, which are co-extruded in three layers. The inner and outer layers are high-quality hard polyvinyl chloride skins and the core layer.
