HDPE mine pipe
Key words:
Water supply pipe, a kind of green, energy saving, environmental protection pipe, no rust, no scaling, no shrinkage, small fluid resistance, can effectively reduce the energy consumption of water supply, improve the water supply point, is an ideal pipe network with pipeline. Water is the source of life and the basis for the survival and development of human civilization. Water crisis has become the focus of common concern of all mankind in the world.
Key words:
Hdpe water supply pipe must withstand a certain pressure, usually to choose a large molecular weight, good mechanical properties of PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding processing, and difficult connection, and is not suitable as a material for water supply pressure pipes. However, due to its high health indicators, LDPE, especially LLDPE resin has become a common material for the production of drinking water pipes. LDPE, LLDPE resin melt viscosity is small, good fluidity, easy processing, so the choice of its melt index is also wide, usually MI between 0.3-3g/10min.
