Description
Technical field
The invention belongs to polymeric material field, and in particular to a kind of anticorrosive wear-resisting PE plastic pipes.
Background technology
Polyethylene（Polyethylene, abbreviation PE）It is a kind of aggregated obtained thermoplastic resin of ethylene.Polyethylene according to
Polymerization, molecular weight height, the difference of chain structure, point high density polyethylene (HDPE), Low Density Polyethylene and linear low density polyethylene
Alkene.Its medium high density polyethylene (HIGH DENSITY POLYETHYLENE, HDPE) is commonly called as low-pressure polyethylene, with LDPE and
LLDPE is compared, and has higher heatproof, oil resistivity, resistance to vapour permeability and environmental stress crack resistance, in addition electrical insulating property and anti-
Impact and cold tolerance very well, are mainly used in the fields such as blowing, injection.HDPE tubing is by made by high density polyethylene (HDPE)
Traditional iron and steel tubing, regeneration product of polychloroethylene pipes, it mainly undertakes appointing for the drainings such as rainwater, sewage, farmland discharging-irrigating
Business, is widely used in highway, railway bed, subway engineering, Landfills, tunnel, greenbelt, sports ground and water content higher
The draining such as side slope protection for causing field, and agricultural, the sub-irrigation of gardening, drainage system.And HDPE in the market
Tubing has that case hardness is low, and the shortcoming of easy scratch strongly limit the use of HDPE pipes, for this purpose, our matching somebody with somebody from product
Side sets about, and develops new high performance HDPE tubing, there is provided a kind of anticorrosive wear-resisting PE plastic pipes.
