Aluminum alloy lining plastic pipe PPR three core technical features

Date:2017-04-19 15:50:23

1, surface treatment technology
Special polymer resin materials Aluminum Alloy surface treatment plastic lining pipe fittings product with PPR Aluminum Alloy outer tube aluminum tube surface color anodized after very coordinated spray, anti ageing, oxygen resistance agent special polymer resin which contains a certain amount of spray in the pipe, on the surface, in addition to the surface of the pipe with the color Aluminum Alloy outer tube color matching, but also on the (PPR PERT Pb) plastic pipe itself has certain anti ultraviolet shielding effect, thus delaying the aging of plastic pipe make it durable for more than 50 years.
2, prestressed composite technology
The physical PPR plastic pipe adopts prestressed technology Aluminum Alloy lining, will have two kinds of materials with different elongation (Aluminum Alloy metal tube and plastic tube) through the prestressed composite technology effectively combine the best, and don't change the physical properties of the 2 kinds of materials, to effectively solve the plastic pipe and pipe with different Aluminum Alloy the application of composite materials in compatibility, sealing; the composite pipe prestressed composite form, in combination with the two kinds of material surface, the design parameters, to obtain the best bonding strength between layers, the composite pipe in thermal expansion and contraction, which reflects the consistency, the Aluminum Alloy plastic composite pipe line 1/5 only pure plastic pipe expansion coefficient about. In the stiffness, strength, aluminum alloy lining plastic composite pipe than a single material (aluminum alloy tube or plastic tube) performance is more excellent.
3, anodic oxidation technology
Aluminum Alloy lining plastic pipe outer tube PPR without anodic oxidation treatment will have serious corrosion, corrosion problems which must be solved fundamentally to improve the protective, decorative and practical function, do the electrochemical treatment (anodic oxidation) the anodic oxidation technology of domestic aluminium is the most widely used and most successful technology the tube surface anodic oxidation in Aluminum Alloy, forming a layer of dense oxide film (three two aluminum oxide), average thickness of more than 10 mu m (CJ/T321-2010 standard). The process of surface oxide film layer there is still a certain gap, therefore, we must further through the sealing technology, effective repair, bridging the gap between the attachment in the oxide film, best film of the aluminum surface to oxidation.
