Overview of nylon polyamide deflashing media

Characteristics and advantages

Nylon polyamide deflashing media has become an ideal choice for cleaning precision instruments with its unique physical and chemical properties. It has good elasticity and softness, and can adapt to the surfaces of precision instruments of different shapes to avoid damage during the cleaning process. At the same time, high wear resistance ensures that the medium can still maintain a good cleaning effect after multiple uses, reducing the frequency of replacement and saving costs. In addition, it has strong chemical stability, good tolerance to a variety of chemicals and cleaning agents, and performs well in various complex working environments.

Current application areas and challenges faced

Nylon polyamide deflashing media are widely used in the automotive, electronics, aerospace, medical equipment and other industries. In the production and processing of automotive parts, burrs and flash are removed to improve the surface quality and assembly accuracy of parts; in the manufacture of electronic equipment, tiny burrs and impurities on chip packaging shells and printed circuit boards are removed to ensure the electrical performance and reliability of electronic components; in the aerospace field, tiny defects on the surface of key components are processed to improve the fatigue strength and safety of components; in the medical device industry, the surface smoothness and cleanliness of surgical instruments and implants are ensured to reduce the risk of infection in patients.

However, with the continuous development of precision instruments and the increasing requirements for cleaning, plastic media blasting also face some challenges. For example, for some extremely tiny particles and stubborn dirt, the removal effect is limited; during the cleaning process, it is difficult to accurately grasp the cleaning effect and the wear of the medium; for precision instruments with complex structures, cleaning is difficult, etc. Therefore, the combination with other equipment and technologies has become a new choice.

Combination of nanotechnology and nylon polyamide media

Application of nanotechnology in the field of materials

Nanotechnology has made major breakthroughs in the field of materials in recent years. By introducing nanoparticles or nanostructures into materials, the properties of materials can be significantly changed. For example, nano coatings can improve the wear resistance, corrosion resistance and self-cleaning ability of materials; nanocomposites have higher strength and toughness, and can also improve thermal stability. Nano metal films have good electrical and thermal conductivity and can be used in electronic components and solar cells. This also provides a reference for the application of nanotechnology in nylon polyamide deflashing media.

Principles and methods of giving nylon polyamide self-cleaning function

Using nano coating technology, a layer of nano coating with super hydrophobic or super hydrophilic properties is coated on the surface of nylon polyamide deflashing media to give it a self-cleaning function. Superhydrophobic coating can make water droplets form balls on the surface, roll off easily, and take away the dirt on the surface; super hydrophilic coating can make water spread quickly, dissolve the dirt and wash away. In addition, nano-photocatalytic technology can be used to load nano-photocatalysts, such as titanium dioxide, on the surface of the medium. Under light conditions, photocatalysts can produce strong oxidation, decompose organic dirt on the surface, and achieve self-cleaning. According to a research report published in the Journal of Facade Design and Engineering: Researchers from Alexandria University in Egypt have successfully developed a self-cleaning nanomaterial, mainly made of doubly doped titanium dioxide (TiO₂), which has photocatalytic properties and can decompose organic pollutants and impurities on the surface when exposed to sunlight, so that the building surface remains clean for a long time and reduces maintenance costs¹.

Ways to enhance the ability to remove tiny particles

In order to enhance the ability of nylon polyamide media to remove tiny particles, nanoparticles can be added to the media. For example, adding nano-magnetic particles, using the effect of magnetic field, makes the medium have a stronger adsorption force on tiny metal particles; or adding nano-adsorbents, such as activated carbon nanoparticles, to improve the adsorption capacity of organic pollutants. In addition, the surface area of ​​the medium can be increased through the design of nanostructures, which can improve the contact and adsorption opportunities for tiny particles. According to news reports, environmental protection company NanoTech Water Solutions has successfully treated tiny particle pollutants in industrial wastewater using nano-adsorption technology, achieving efficient purification of wastewater².

Actual application cases and effect analysis

From websites such as Semiconductor Engineering, it is learned that some semiconductor manufacturing companies use nylon polyamide media treated with nanotechnology to clean chip packaging shells. These nano-treated media can effectively remove tiny particles, reduce surface roughness, and improve insulation resistance. After using this medium, the number of tiny particles on the surface of the chip package was reduced by more than 50%, and the surface roughness was reduced by about 30%.

In the manufacturing process of electronic components, PA6 media treated with nanotechnology is used to clean circuit boards and other small parts, which can more effectively remove residual solder and other contaminants and reduce losses and equipment wear during the cleaning process. The cleaning efficiency of using this medium is increased by 20%, and the material consumption during the cleaning process is reduced by 15%.

Fusion of smart sensors and nylon polyamide media

Implementation method of real-time monitoring of the cleaning process

Combining smart sensors with nylon polyamide deflashing media can realize real-time monitoring of the cleaning process. For example, installing a pressure sensor in the cleaning equipment can monitor the pressure changes during the cleaning process, so as to judge whether the fluidity and injection angle of the medium are appropriate; installing an optical sensor can monitor the surface quality of precision instruments after cleaning in real time, such as whether there is residual dirt. For example, Bosch provides a series of smart sensors and automation solutions for quality monitoring in the automotive manufacturing process, including the cleaning process; Dürr also provides smart cleaning solutions and monitoring systems for improving the cleaning quality and process control of automotive parts, and has achieved good results.

Strategies for optimizing the cleaning process

By using smart sensors to monitor the parameters of the cleaning process in real time, corresponding strategies can be adopted to optimize the cleaning process. If the pressure sensor detects that the pressure is too high, the parameters of the cleaning equipment can be adjusted to reduce the pressure to avoid damage to the precision instrument; if the optical sensor detects that there is still residual dirt on the surface, the cleaning time can be extended or the cleaning process can be adjusted. In addition, the data feedback of the smart sensor can be used to establish a model of the cleaning process to achieve intelligent control of the cleaning process.

Case analysis and data display
