摘要
PP -R管道具有质轻、连接方便、良好耐热性和较小导热系数、耐腐蚀且管道阻力小等优点 ,属绿色产品 ,本文对施工过程中就PP -R管与混凝土的粘结不密。
PP-R pipeline is characterized by it's light wt. convenience to connect, good heat-resistance? small heat-conductance coefficient, corrosion resistance and small hydraulic resistance. It is a green product. The disadvantages are difficulty to stick PP-R pipes with concrete tightly and poor resistance to UV, therefore counter-measures were suggested.
