Embodiment 1

[0019] A compressor anti-corrosion treatment method is carried out in the following order:

[0020] (1) Pickling the compressor first;

[0021] (2) Rinse the cleaned compressor with clean water and let it dry naturally;

[0022] (3) Dip the shell of the cleaned and dried compressor into the molten surface treatment agent to form an anti-corrosion coating. The surface treatment agent is composed of the following components and proportioned by weight percentage: polytetrafluoroethylene 4 %, Dimethylformamide 12%, Trifluoroacetyl Chloride 6%, Triethyl Benzene Tricarboxylate 4%, Zinc Undecylenate 7%, Tetranitrotetrazolium Blue 12%, Carbon Nanotube 14% , trifluoroethyl acrylate 6%, nano-diamond 10%, magnesium reagent 6%, dioctyl sebacate 6%, trifluoromethoxybenzene 9%, diphenylphosphoryl chloride 4%.

[0023] (4) Put the soaked compressor casing into the furnace for drying, raise the temperature of the furnace to 500°C, keep it for 10 hours, then raise the temperature of the furn...

Abstract

The invention discloses a compressor surface treating agent and an anti-corrosion treatment method. The surface treating agent is prepared from the following components in percentage by weight: 1%-6%of polytetrafluoroethylene, 6%-18% of dimethyl formamide, 5%-7% of trifluoroacetyl chloride, 2%-6% of triethyl benzene tricarboxylate, 3%-7% of zinc undecylenate, 6%-12% of tetranitrotetrazole blue, 10%-15% of carbon nanotubes, 2%-6% of trifluoroethyl acrylate, 5%-10% of nano diamond, 1%-6% of a magnesium reagent, 3%-6% of dioctyl sebacate, 3%-9% of trifluoromethoxybenzene and 2%-4% of diphenyl phosphoryl chloride. The compressor surface treating agent can be effectively prevented from being corroded, the service life of the compressor is prolonged, the investment cost of an enterprise is reduced, and good application prospects are achieved.

Description

technical field [0001] The invention relates to the technical field of compressors, in particular to a compressor surface treatment agent and an anti-corrosion treatment method. Background technique [0002] A compressor is a driven fluid machine that elevates low-pressure gas to high-pressure gas, and is the heart of the refrigeration system. It inhales low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle. Compressor casings are usually stamped from hot-rolled or cold-rolled mild steel, or constructed of gray cast iron. Therefore, it is usually necessary to form an anti-corrosion coating on the casing of the compressor for protection, otherwise the compressor will be highly susceptible to corrosion. Especially in the marine atmospheric environment, the comp...
