Problems solved by technology
[0002] Products made of general metals such as copper or iron, or the metal surface of some outdoor facilities, are prone to corrosion failures when used in special environments such as acidic, alkaline, and salty particles. At present, Taiyi paint is generally used to paint Anti-corrosion solution for membrane protection, but its metal surface is still prone to corrosion problems
Especially for the pipeline system of the existing air conditioner, since the current air conditioner generally uses copper pipes to form the pipeline system, this type of pipeline system is used in the special environment such as acid, alkali, and salty particles mentioned above , the corrosion rate will increase exponentially, because the anti-corrosion ability is limited, the pipeline is prone to leakage due to corrosion, and the service life of the product will be reduced

Embodiment Construction
[0016] The present invention will be described in detail below with reference to the accompanying drawings and examples.
[0017] figure 1 A schematic structural diagram of the first embodiment of the metal part is shown. In this embodiment, the metal part may be common materials such as copper, iron or aluminum. like figure 1 As shown, the metal part of the present embodiment comprises a metal body 1, the outer surface of the metal body 1 has a first layer of paint 2, the first layer of paint 2 is a zinc-rich primer, and the main components of the zinc-rich primer are epoxy resin and zinc powder, which can effectively improve the anti-rust ability and play the role of sacrificial anode cathodic protection. There is also a second layer of paint 4 on the outer layer of the first layer of paint 2, the second layer of paint 4 is a tetrafluorocarbon topcoat, the main component of the tetrafluorofluorocarbon topcoat is tetrafluoroethylene-vinyl ether copolymer, It has excellent ...

The invention provides a metal part. The metal part comprises a metal body. The outer surface of the metal body is provided with a first oil paint layer and a second oil paint layer arranged outside the first oil paint layer. The first oil paint layer is an epoxy zinc rich primer layer, and the second oil paint layer is a polytetrafluoroethylene fluorocarbon paint layer. The metal part is sprayed with multiple oil paint layers or is processed in a wiping mode. The metal part has the good antiseptic property, and the normal product service life is ensured.
Description
technical field [0001] The invention relates to the field of metal manufacturing, in particular to a metal piece and its surface treatment method, a pipeline system and an air conditioner.
