According to customer demand for the production of different
specifications production
Through long-term efforts Qingdao Huashida Machinery Co.Ltd. has
produced 3PE coating production line, so that meetthe demand of
more customer. It indicating the direction of the 3PE coating
production line with high performance.
The composition of 3-layer PE coating production line
The three -layer PE anticorrosion structure includes fusion bonded
epoxy-powder bottom layer, polymer adhesive middle layer and
polyethylene top layer. The so-called 3-layer PE Coating Production
line,3-layer refers to the 3-layer structure of epoxy primer, that
is a thermosetting, non-toxic coating, curing after form high
molecular weight cross-linked structure coating, With excellent
chemical corrosion resistance and high mechanical properties,
especially the best wear resistance and adhesion. It can form a
continuous coating and steel pipe surface directly bonded, with
good resistance to chemical corrosion and anti-cathode stripping
performance.
To ensure that the overall coating at a higher temperature Has a
good adhesion, making the middle layer of adhesive reactive groups
to form a chemical bond. That is high quality of steel pipe
anti-corrosion coating buried in the ground.
The intermediate layer is usually a copolymer binder, the main
component of which is polyolefin, and is widely used as a vinyl
copolymer adhesive. The polar moiety of the copolymer adhesive and
the epoxy group of the epoxy primer can react to form hydrogen
bonds or chemical bonds to form a good bond between the
intermediate layer and the substrate; and the non-polar ethylene
moiety has a Good affinity, so the middle layer and the surface
layer also has a good bonding performance. Three-layer structure of
polyethylene anti-corrosion, as the buried pipe outside the
protective layer is very superior, and the technology has been
widely used in the West-East Gas and oil field oil supply, urban
gas supply, water pipeline used on the anti-corrosion.
