Description
Technical field
The present invention relates to conveyance conduit, more particularly to a kind of corrosion-resistant and anti abrasive steel-plastics composite pipe.
Background technology
Steelplastic pipe is found broad application as a kind of engineering tubing in fields such as municipal administration, chemical industry, mining.However, common
Polypropylene steelplastic pipe due to transporting various industrial liquids for a long time, and liquid often has corrosivity and temperature change is very big, to compound
The influence of pipe layers cementing intensity and intermediate layer steel band is very big, this with regard to an urgent demand steelplastic pipe inwall have preferably it is wear-resistant and
Resistance to chemical corrosion.
The appearance of graphene brings hope to cracking for this problem.Graphene is that current mechanics known in the world is strong
Spend highest (fracture strength 130GPa, Young's modulus 1.0TPa), most thin (thickness 0.3nm), most conductive (resistivity 10-6 Ω
Cm, slightly below most conductive argent), (thermal conductivity reaches 5000W/mk at room temperature, more than being currently known thermal conductivity for most heat conduction
Highest diamond) etc. performance.These excellent properties of graphene so that it is comprehensive that graphene very likely turns into raising plastic conduit
Close the material of performance.
