AI Technical Summary

Technical Problem

The existing anti-corrosion process of the sampler can easily cause the anti-corrosion layer to fall off, causing the sampler to be corroded.

Method used

Frosted treatment is used to enhance the adhesion of the component surface, and a rare earth preservative and an oxygen-blocking resin layer are used to prevent the anti-corrosion layer from falling off under impact and friction, and to prevent the penetration and diffusion of O2 and H2O in the atmosphere.

Benefits of technology

It effectively prevents the anti-corrosion layer from falling off, enhances the adhesion between the anti-corrosion layer and the sampling tube, reduces the corrosion rate, and protects the sampler components.

Abstract

The invention discloses an anti-corrosion treatment process for parts of a sampling machine. The anti-corrosion treatment process comprises the following steps that 1), impurity removal and rust removal are carried out on the surface of each part of the sampling machine; 2), sanding is carried out on the surface of each part which is subjected to the treatments in the step 1) of the sampling machine; 3), a sampling pipe of the sampling machine is soaked in rare-earth preservative which is subjected to a curing treatment, the rare-earth preservative is taken out after deposited on the surface of the sampling pipe, and then the rare-earth preservative is naturally air-dried at normal temperature; 4) the rare-earth preservative which is subjected to the curing treatment is sprayed on the surfaces of the other parts of the sampling machine; and 5), the sampling pipe which is subjected to the treatment in the step 3) is coated with an antioxygenic resin layer, and the other parts of the sampling machine are coated with the antioxygenic resin layer. According to the anti-corrosion treatment process, on one hand, the corrosion-resistant layer can be prevented from being impacted and rubbed and the anti-corrosion layer is firmly adhered to the surface of the sampling pipe, and on the other hand, the problem that the surface of the sampling pipe is corroded and damaged as oxygen and water in the atmosphere permeate and diffuse to the surface of the sampling pipe can be prevented.
