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 epoxy powder is a kind of thermosetting
nontoxic coating, forming the high molecular weight cross-linking
structure coating after solidifying, featuring, featuring good
chemical anticorrosion and high molecular mechanical properties.
The function of epoxy-powder bottom layer is to form continuous
coating, providing excellent and cathodic disbanding resistance.
The function of polymer adhesive is to agglutinate the epoxy powder
before gelation, and to agglutinate the polyethylene top layer,
which unites all three layers together. The three-layer PE process,
with the epoxy powder coating as bottom layer, binding and bundling
through polyethylene PE and adhesive, is widely used in
anticorrosion of steel pipes at home and abroad, and applied to the
oil pipeline and gas pipeline, as well as to the gas supply and
water supply for civil use.
