Embodiment Construction

[0012] The specific implementation of the present invention will be further described below in conjunction with the examples. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0013] The technical scheme of concrete implementation of the present invention is:

[0014] A U-shaped heating tube, comprising a stainless steel main body, the outer surface of the stainless steel main body is sintered with a protective layer, and the protective layer is composed of the following components in parts by weight:

[0015] 6.7 parts polyurethane resin,

[0016] 2.3 parts ethylene bis stearamide,

[0017] 1.2 parts of vinyltrimethoxysilane,

[0018] 0.9 parts modified polysiloxane,

[0019] 0.4 parts silicon dioxide,

[0020] 1.6 parts of allyl heptanoate.

Abstract

The invention discloses a U-shaped heating tube which comprises a stainless steel main body, wherein a protecting layer is sintered on the outer surface of the stainless steel main body; the protecting layer is prepared from the following components in parts by weight: 6.7 parts of polyamino resin, 2.3 parts of ethylene bis stearamide, 1.2 parts of vinyl trimethoxy silane, 0.9 part of modified polysiloxane, 0.4 part of silicon dioxide and 1.6 parts of allyl heptanoate. As the protecting layer which is good in anti-corrosion anti-scale property, good in thermal resistance and oxidation resistance and high in hardness is sintered on the outer surface of the stainless steel main body, the service life of the U-shaped heating tube is prolonged.

Description

technical field [0001] The invention relates to a U-shaped heating pipe. Background technique [0002] The existing U-shaped heating tubes need to be improved in anti-corrosion, anti-scaling and anti-oxidation properties, and the service life of the U-shaped heating tubes is greatly affected. Contents of the invention [0003] The object of the present invention is to provide a U-shaped heating tube. The sintered surface of the stainless steel main body has a protective layer of anti-corrosion, anti-scaling, anti-oxidation and high hardness, which can improve the service life of the U-shaped heating tube. [0004] In order to achieve the above object, the technical solution of the present invention is to design a U-shaped heating tube, including a stainless steel body, and a protective layer is sintered on the outer surface of the stainless steel body, and the protective layer is composed of the following components in parts by weight: [0005] 6.7 parts polyurethane resi...
