Reduce the friction resistance of valves and pipelines and improve fluid transmission efficiency

Powder coating is a solid powder coating composed of resin, curing agent, pigment, filler and additives. It is applied to the surface of the substrate by electrostatic spraying, fluidized bed dipping and other processes, and then heated and cured to form a continuous coating film. Compared with traditional solvent-based coatings, powder coatings have the advantages of environmental protection, high efficiency, energy saving, and easy automation construction. Therefore, they have been widely used in the surface treatment of industrial parts such as valves and pipelines.

Optimize the powder coating formula to reduce the friction coefficient

Selection of resin and curing agent: Resin and curing agent are the main components of powder coatings. Their selection directly affects the hardness, toughness, wear resistance and friction coefficient of the coating. In order to obtain a coating with a low friction coefficient, it is necessary to select resins and curing agents with low surface energy and good lubricity. For example, fluorine-containing resins, polytetrafluoroethylene (PTFE), etc., due to their unique molecular structure, can effectively reduce the surface energy of the coating, thereby reducing the friction between the fluid and the coating.

Addition of fillers: Adding an appropriate amount of fillers such as nano-silica, graphite, talcum powder, etc. to powder coatings can further reduce the friction coefficient of the coating. These filler particles form a tiny lubricating layer in the coating film, which effectively reduces the direct contact area between the fluid and the coating film, thereby reducing friction resistance.
The role of additives: Additives play a role in regulating coating performance and improving construction conditions in powder coatings. By adding an appropriate amount of leveling agent, defoamer, antistatic agent, etc., the fluidity and curing process of the coating can be optimized, thereby obtaining a smoother and more uniform coating film and further reducing the friction coefficient.

Optimization of coating process
Electrostatic spraying technology: Electrostatic spraying is one of the most commonly used coating methods for powder coatings. The powder particles are charged by a high-voltage electrostatic field and adsorbed on the negatively charged surface of the valve pipe to form a uniform coating. Electrostatic spraying technology has the advantages of high coating efficiency, good coating quality, and low environmental pollution. It is a key step to reduce the friction coefficient and improve the performance of the coating film.
Heating and curing process: Powder coatings need to be heated and cured after coating to make the resin and curing agent react chemically to form a continuous coating film. The choice of curing temperature, time and method has an important influence on the performance of the coating film. By optimizing the curing process, it is possible to ensure that the coating is fully cured while avoiding performance degradation caused by overheating.
Coating thickness control: Coating thickness is one of the important factors affecting the friction coefficient. A coating that is too thick will increase the contact area between the fluid and the coating, thereby increasing the friction resistance; while a coating that is too thin may not provide sufficient lubrication. Therefore, the coating thickness needs to be strictly controlled during the coating process to ensure that the coating has the best lubrication performance.

Application effect of extremely low friction coefficient coating
Reducing friction resistance: The extremely low friction coefficient coating obtained by optimizing the pipeline powder coating formula and coating process can significantly reduce the friction resistance of the fluid in the valve pipeline. This not only reduces the energy loss during fluid transmission, but also improves the fluid transmission efficiency of the system.
Reducing energy consumption: Reducing friction resistance means reducing the pumping power required for fluid transmission, thereby reducing the energy consumption of the system. This has significant economic benefits for industrial systems that require long-term continuous operation.
Extended service life: The extremely low friction coefficient coating can also effectively reduce the scouring and wear of the valve pipeline by the fluid, extending its service life. This not only reduces the cost of replacement and maintenance, but also improves the stability and reliability of the system.
Improve system performance: By reducing friction and energy consumption, the ultra-low friction coefficient coating can also improve the performance of the entire fluid transmission system. For example, in the chemical, oil, and natural gas industries, the application of this technology can significantly improve production efficiency and reduce operating costs.
