In modern industry, the performance of boiler pipelines directly affects the efficiency and safety of the entire system. Therefore, choosing the appropriate surface coating material is of vital importance. In recent years, arc-sprayed PS45 material coatings have attracted extensive attention due to their superior performance. This article will explore why arc-sprayed PS45 material coating is chosen for boiler pipes, as well as the advantages and improvement space it brings.
The arc-sprayed PS45 material coating has excellent wear resistance and corrosion resistance, which can effectively extend the service life of boiler pipes. Boiler pipes operate in high-temperature and high-pressure environments, making them prone to corrosion and wear. However, the PS45 coating can form a strong protective film, reducing the occurrence of these problems. In addition, this coating has strong adhesion and can form a good bond with the surface of boiler pipes, ensuring long-term stable performance.
2. The preparation and strengthening of surface coatings for boiler pipes are crucial steps to enhance their overall performance. By properly cleaning and treating the surface of the pipes, the adhesion and durability of the coating can be enhanced, thereby further improving the operational efficiency of the boiler. Improving the application process and material selection of coatings can effectively reduce maintenance costs and enhance production efficiency.
3. Boiler pipes coated with arc-sprayed PS45 material not only reduce downtime due to faults but also lower the frequency of maintenance and replacement, thereby saving a significant amount of operating costs. In addition, enhancing the performance of boiler pipes also helps to improve overall production efficiency and strengthen the market competitiveness of enterprises.
In conclusion, choosing arc-sprayed PS45 material coating for boiler pipes not only improves the performance of the pipes but also brings significant economic benefits to enterprises.
Arc Spraying PS45 Common Problems
I. Coating and peeling
Reasons:
Base spray is not clean and not rough enough
Staining too long after sand spraying and rusting
The spray distance was too far and the binding force was insufficient
Solution:
Sandblasting to Sa2.5, roughness Ra40 or more; Apply within 2 hours of sand spraying; Control spraying distance of 150-200 mm.
II. Corrosion of the Coating
Reasons:
One blow was too thick, and the internal stress was great.
Interlayer temperatures are too high
The substrate was not preheated and the temperature difference was large
Solution:
Spray in layers, and do not thicken the single layer;Interlayer temperature ≤ 80 ° C;Base material is preheated at 80 - 120 ° C.
III. The coating is loose, there are many needles, and the corrosion protection is poor
Reasons:
The voltage current is unstable, and the vaporization is not good
The angle of spraying was not right, too far.
No sealing hole or no sealing hole is in place
Solution:
Stability parameters 30-38 V / 180-250A;Angle 60-90 °;High temperature seals must be made.
IV. The wire delivering is not smooth, the wire is broken, the short circuit
Reasons:
Silk is bent, damp, and dirty on the surface
The conductive nozzle worn out and the two filaments are not in sync
Solution:
Use straight, dry silk; Timely replacement of conductive nozzles; Ensure that the transmission wire is uniform and stable.
V. The coating becomes black and brittle
Reasons:
Insufficient wind pressure and severe oxidation
The workpiece overheated
Solution:
Ensure the pressure of the air compressor is stable; Increase wind cooling and control temperature.
VI. The thickness is uneven and locally too thick
Reasons:
The spray gun was not moving at a steady pace and the overlapping rate was inconsistent
Solution:
Shot at a uniform speed, overlap 1 / 3 to 1 / 2, divided and segmented spray.
