Abstract
A compressor includes a housing, and an anticorrosive coating covering a surface of the housing. The anticorrosive coating includes a base layer applied on the surface of the housing, and a surface layer applied on the base layer. Both the base layer and the surface layer are organic coatings. Thus, the housing of the compressor is effectively separated from the external environment by means of the two organic coatings, so as to ensure that the compressor is not corroded; moreover, the anticorrosive coating does not contain a metal coating, thereby preventing the problem of the compressor being severely corroded due to an exposed metal coating.
Claims11
A compressor, comprising a housing and an anticorrosive coating layer covering a surface of the housing, wherein the anticorrosive coating layer does not comprise a metal coating layer and comprises a phosphating layer applied on the surface of the housing, a base layer applied on the phosphating layer and a surface layer applied on the base layer, and the base layer and the surface layer are both organic coating layers,
- wherein a material of the base layer is epoxy resin and a material of the surface layer is acrylic amino resin,
- wherein a thickness of the base layer is in a range of 45 μm to 95 μm, and a thickness of the surface layer made of acrylic amino resin is in a range of 10 μm to 40 μm.
A processing method of a compressor, configured to form an anticorrosive coating layer of the compressor, the processing method comprising:
- performing a surface treatment to form a phosphating layer on a surface of a housing of the compressor;
- applying a first organic coating onto the surface of the housing of the compressor, to form a base layer made of an epoxy resin system coating with a thickness in a range of 45 μm to 95 μm;
- and
- applying a second organic coating onto a surface of the base layer, to form a surface layer made of an acrylic amino system coating with a thickness in a range of 10 μm to 40 μm,
- wherein the anticorrosive coating layer of the compressor does not comprise a metal coating layer.
