Description
Technical field
The invention belongs to plastic conduit technical fields, and in particular to a kind of shock resistance, the polythene drainpipe of crack resistence.
Background technique
PE is vinyon, a kind of most basic plastics, and polybag, preservative film etc. are all PE, and HDPE is a kind of crystallization
Degree height, nonpolar thermoplastic resin.The milky appearance of ortho states HDPE, in meagre section in a degree of translucent
Shape.PE has the characteristic of excellent resistance to most of lives and chemicals for industrial use.
PE pipe has medium density polyethylene pipe and high density polyethylene pipe.Compare with steel pipe, construction technology is simple, has certain
Flexibility will save a large amount of process more important is preservative treatment is not used as.Disadvantage is not so good as steel pipe with regard to instrument, in construction
The special safe spacing for paying attention to heating power heating, and cannot be exposed in air under sunlight, and be used to drain in industry,
It is easy the expansive force bursting by freezing in low temperature environment by internal junction ice water.
Notification number is that the Chinese patent of CN207005472U discloses a kind of frost-cracking-preventing PE water pipe, including PE pipeline body,
The PE pipeline body is disposed with antibiotic layer, PE layers, insulating layer, enhancement layer, flame-retardant layer from the inside to the outside；The PE layer
Inside it is provided with toroidal cavity；The toroidal cavity is arranged between PE layers of left and right ends, and close to PE layers of inside.Low
Under the conditions of temperature, when the water freezing in water pipe, water volume expansion due to phase transformation, the pressure that PE layers of inside is subject to increases, and causes
PE layers of inside spalling provides space now close to the toroidal cavity of PE layers of inside for the volume that water is expanded by phase transformation, makes
In ice pressure reduce, thus prevent entire PE layers by excessive pressure spalling ontology, but the structural cavities two sides by
It is easy to happen damage in cavity inside mechanical force, leads to the mechanical damage of pipeline.
Summary of the invention
In order to solve the shortcomings of the prior art, the invention discloses a kind of shock resistances, the polyethylene drainage of crack resistence
Pipe, the present invention are to make drainpipe that can reach certain toughness and machinery by being modified and combining multilayer to be arranged to material
