16 * 2 sanitary stainless steel tube wet polishing process significantly improve the surface finish and smoothness of the tube surface

Sanitary stainless steel tube polishing belongs to a finishing technology, its purpose is to enhance the surface finish and smoothness of the tube surface, so that it can achieve the desired surface quality, the polishing process generally involves the use of fine micron or submicron abrasive particles combined with a liquid to carry out the “wet” polishing, this process is extremely important in the processing of sanitary stainless steel tube. This process is extremely important in the processing of sanitary stainless steel tubes because it removes minor surface defects, improves smoothness, enhances corrosion resistance and cleanliness.

Among the processes that combine liquid media with fine micron or sub-micron abrasive particles is a method called wet polishing. The main difference between this method and conventional polishing is the use of a liquid medium, which facilitates better control of the polishing process and thus improves surface quality. Water, chemical additives and abrasive particles make up the liquid medium, with the abrasive particles being the key ingredient that determines the polishing result.

In the wet polishing process, the size and shape of the abrasive particles have an important influence on the polishing result. Fine micron or sub-micron abrasive particles with high surface energy and abrasive properties are able to cut through the surface of the tube better, resulting in a higher degree of finish and smoothness. In addition, these abrasive particles are able to penetrate better into the microstructure of the tube surface and remove deep surface defects.

To evenly distribute the abrasive particles in the liquid medium, generally have to add the right amount of chemical additives, such additives can improve the suspension and dispersion of the abrasive particles, and thus improve the polishing effect, the commonly used chemical additives cover surfactants, pH adjusting agents, oxidising agents and so on.

In the process of sanitary stainless steel tube polishing, the use of wet polishing process can significantly improve the surface finish and smoothness of the tube. First of all, the sanitary stainless steel tube to be polished to be immersed in the kind of liquid medium containing abrasive particles and chemical additives. Then, with the help of mechanical vibration or rotation of such a way, so that the abrasive particles and tube surface friction, in order to remove surface defects. In this friction process, the liquid medium plays a cooling, lubricating and cleaning effect, can reduce heat generation, improve the efficiency of polishing, and maintain the cleanliness of the tube surface.

In order to better control the polishing process, generally have to accurately control a number of process parameters, such as temperature, pressure and liquid quality, temperature if high will cause the liquid medium to evaporate very quickly, thus reducing the efficiency of the polishing, if the temperature is too low, it is possible to cause the liquid medium to solidify or freezing, which has an impact on the effect of the polishing, so the selection of appropriate temperature range is particularly critical to the So, selecting the appropriate temperature range is particularly critical to maintain the quality of polishing.

Pressure is one of the important factors affecting the polishing effect, too high a pressure may cause excessive wear and tear or deformation of the surface of the tube, thereby reducing the surface quality, too low a pressure may result in a bad polishing effect, so, according to the tube material, abrasive particles, and the characteristics of the liquid medium to select the appropriate pressure range.

The quality of the liquid has an important influence on the polishing result. If the liquid medium, the accumulation of excessive abrasive particles, or other impurities, will lead to its cooling, lubrication and cleaning effect is reduced, resulting in a decline in polishing efficiency. Therefore, the liquid media should be replaced regularly to maintain its cleanliness and effectiveness.

After polishing, the sanitary stainless steel tubes are cleaned and then tested and evaluated. The purpose of cleaning is to remove the residual abrasive particles on the surface of the tube as well as the liquid medium to ensure surface cleanliness. After cleaning, the use of optical surface profiler, atomic force microscope and other testing equipment, the tube surface testing, assessment of its finish and smoothness is not to meet the requirements.

The implementation of wet polishing process, in the sanitary stainless steel tube polishing link has a key effect, with the help of letting the fine micron or submicron abrasive particles and liquid combination of ways, can greatly enhance the degree of surface finish and smoothness of the tube to improve the corrosion resistance and cleanliness, in the pursuit of reaching the optimal polishing effect, to accurately control a number of process parameters, such as temperature, pressure, liquid quality, and so on. In the pursuit of achieving the best polishing effect, to accurately control some process parameters, such as temperature, pressure, liquid quality, etc., and, after the end of the polishing work, but also for the sanitary stainless steel tube cleaning, testing and evaluation.
