Precision petroleum mesh through the etching process

Precision oil mesh is a kind of filtration material widely used in the oil industry, which is mainly used in oil filtration, dewatering and deslagging. In order to manufacture this kind of mesh, firstly, we need to use high strength, corrosion-resistant and high temperature-resistant materials, such as stainless steel, nickel-based alloy and so on. Next, we will etch and process these materials to achieve the required precision and surface quality.

1、 Preparation stage

Before starting the etching processing of precision petroleum mesh, the raw materials need to be pre-treated. First, the surface of the material is polished smooth using a mechanical polishing machine to remove burrs and oxidized layers. Then, chemical cleaning is performed to remove grease and other dirt. These pretreatment steps are to ensure the precision and surface quality of mesh etching processing.

2、 etching processing

1. Make mask

In the precision petroleum mesh before the etching process, the need to make the corresponding mask according to the design drawings. Mask is a protective film, used to protect the part that does not need to be etched. The process of making the mask includes transforming the design drawings into mask graphics and transferring them to the substrate coated with photosensitive materials.

2. Exposure

The mask is placed on the material to be etched and then exposed. At this point, the graphics on the mask are transferred to the material in preparation for the next step of etching.

3.Etching

The exposed material is placed into the etching solution, which will dissolve the material to be removed. During this process, a mask will protect the parts that do not need to be etched.

4. Remove Mask

After the etching is completed, the mask is removed. At this time, the material will remain on the etching completed graphics.

3、 post-processing

1. Cleaning

After removing the mask, the material is cleaned to remove residual etching solution and other dirt.

2.Inspection

After cleaning, the mesh is inspected to ensure that it meets the design requirements. At this stage, a magnifying glass or microscope can be used to check the precision and surface quality of the mesh. If problems are found, it needs to be trimmed or reworked accordingly.

3.Packaging

After the precision petroleum mesh etching process is checked, packaging is carried out. Before packaging, you can use a desiccant to remove the moisture on the mesh to avoid rust and corrosion after packaging. Then, the mesh will be placed in a special bag, and extract a vacuum for sealing. This protects the mesh from the environment and the effects of transportation. Finally, the packaged mesh is sent to the delivery location.

IV. Summarize

Through the above steps, we have successfully completed the etching process of precision petroleum mesh. In this process, the process parameters and operation details of each step play a key role in the final product quality and precision. Therefore, operators must undergo strict training and assessment to ensure the stability and consistency of the processing.
