[0005] The epoxy resin used in the existing graphene anti-corrosion coating has poor flexibility, resulting in poor coating quality; at the same time, the residual stress of the existing graphene anti-corrosion coating during the curing process will cause the coating to crack, and the weather resistance is poor, easy to pulverize, and the high temperature Poor resistance to strong corrosive media, etc.
[0006] The existing ultrasonic phase noise measurement methods all use special hardware circuits to extract the phase information of the signal source under test, and use this to analyze the SSB phase noise of the signal source under test, so that the extraction performance of the phase extraction circuit is largely It determines the performance of phase noise measurement, and the frequency response of the phase extraction circuit will also affect the measurement results
[0007] At present, the usual flexible epoxy resin preparation equipment produces a large amount of moisture when drying raw materials, which is not easy to discharge in the mixing tank, and it is easy to cause the tank wall to rust
When the staff put the nylon raw material into the feed tank, a large amount of dust will be generated in the feed tank, which will affect the health of the staff
At present, the thermal efficiency of dryers in this industry is low, and installation and operation are inconvenient

Description
technical field [0001] The invention belongs to the technical field of anti-corrosion materials, and in particular relates to a graphene anti-corrosion coating, a preparation method and a management method. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: [0003] Anti-corrosion coatings are generally divided into conventional anti-corrosion coatings and heavy-duty anti-corrosion coatings, which are an indispensable coating in paint coatings. Conventional anti-corrosion coatings play an anti-corrosion effect on metals under normal conditions and protect the service life of non-ferrous metals; A type of anti-corrosion coating that achieves a longer protection period than conventional anti-corrosion coatings. However, the epoxy resin used in the existing graphene anti-corrosion coatings has poor flexibility, resulting in poor coating quality; at the same time, the residual stress of the existing graphene anti-c...
