Kind Code:
A1
Abstract:
Disclosed is a peroxide-crosslinked polyethylene (PEX-a) pipeline. The peroxide-crosslinked polyethylene (PEX-a) pipeline of the present utility model comprises a PEX-a antimicrobial layer, a PEX-a main body layer and an anti-UV layer sequentially bonded from inside to outside. By arranging the anti-UV layer outside the PEX-a main body layer, the weather resistance of the pipeline can be improved, so that the anti-aging performance of the pipeline is improved and the service life thereof is prolonged; and by arranging the PEX-a antimicrobial layer inside the PEX-a main body layer, the growth and reproduction of bacteria in water in the pipeline can be inhibited, and the water quality of drinking water is improved.
