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.

Example Embodiment

[0021] Example 1:
[0022] The anti-corrosion treatment process of sampling machine components includes the following steps:
[0023] 1) The surface of each part of the sampling machine is cleaned of impurities and rust;
[0024] 2). The surface of each part of the sampling machine after step 1) is frosted;
[0025] 3). Immerse the sampling tube of the sampling machine in the matured rare earth preservative. After the rare earth preservative is deposited on the surface of the sampling tube, take it out and dry it naturally at room temperature. The temperature of the sampling tube during the immersion deposition process is 80 ℃, the immersion time is 30minmin, the rare earth preservative is a mixture of aminopropyltriethoxysilane, lanthanum oxide, ethanol and deionized water in a weight ratio of 3:1:3:4, and the curing treatment Is to stand for 60 hours at room temperature;
[0026] 4) Spray the surface of other parts of the sampling machine with the cured rare earth preservative;
[0027] 5). The sample tube after step 3) is sprayed with an oxygen barrier resin layer, and other parts of the sampling machine are sprayed with an oxygen barrier resin layer. The thickness of the oxygen barrier resin layer is 50 μm.

Example Embodiment

[0028] Example 2:
[0029] The anti-corrosion treatment process of sampling machine components includes the following steps:
[0030] 1) The surface of each part of the sampling machine is cleaned of impurities and rust;
[0031] 2). The surface of each part of the sampling machine after step 1) is frosted;
[0032] 3). Immerse the sampling tube of the sampling machine in the cured rare earth preservative. After the rare earth preservative is deposited on the surface of the sampling tube, take it out and dry it naturally at room temperature. The temperature of the sampling tube during the immersion deposition process is 130 ℃, the immersion time is 60min, the rare earth preservative is a mixture of aminopropyltriethoxysilane, lanthanum oxide, ethanol and deionized water in a weight ratio of 3:1:3:4, and the aging treatment is Let stand for 70 hours at room temperature;
[0033] 4) Spray the surface of other parts of the sampling machine with the cured rare earth preservative;
[0034] 5). The sample tube after step 3) is sprayed with an oxygen barrier resin layer, and other parts of the sampling machine are sprayed with an oxygen barrier resin layer. The thickness of the oxygen barrier resin layer is 200 μm.
