With the rapid advancement of science and technology, an increasing number of technological products have become part of everyday life and are even widely employed in industrial production. In the coating industry, non‑curing spray machines have found extensive application. Next, I will discuss the key features of these machines to help you better understand this type of equipment. Non‑curing spray machines operate under favorable environmental and working conditions. Currently, the most commonly used models are typically paired with inspection conveyors, enabling the creation of continuous spray‑coating production lines. In such setups, operators primarily focus on preparing workpieces, loading and unloading equipment, and monitoring adjustments, thereby minimizing direct contact with the coating material and reducing physical labor. Moreover, during operation, the dispersion range of oil mist from non‑curing spray machines is significantly shorter than that of air‑pressure or high‑pressure spraying, which helps mitigate workplace contamination—a factor of great importance for operator health.

Seepage in underground structures can cause the dissolution of calcium hydroxide in reinforced concrete and a reduction in pH, thereby promoting corrosion of the reinforcing steel and accelerating alkali–aggregate reactions in the concrete. This compromises structural safety and shortens the service life of the project. Using a non‑curing spray machine yields high paint utilization. During spraying, negatively charged paint particles are uniformly deposited onto the workpiece surface along the direction of the electric field, minimizing rebound and overspray. As a result, coating loss is minimal, and paint utilization can reach 85% to 90%. Moreover, thanks to the excellent performance of the non‑curing spray machine and operators’ strict adherence to proper procedures, the coating exhibits excellent dispersion under the influence of a high‑voltage electrostatic field, ensuring relatively uniform distribution during application. Consequently, the resulting coating on the workpiece surface is smooth and even, with superior gloss and strong adhesion.

Finishing efficiency is high. Production experience shows that the conveyor speed of electrostatic spray‑coating continuous lines can reach 24 m/min, significantly exceeding that of other coating lines. The overall economic benefits of non‑curing spray equipment are particularly pronounced for wooden components with frame structures—such as tables, chairs, and frames—that cannot be coated by conventional spraying or roller application.

The primary drawback of the non‑curing spray method is its high fire risk; sparks or electrical discharges resulting from improper spraying distances or operator error can easily ignite fires. Therefore, reliable fire‑ and explosion‑proof measures must be in place, and safety operating procedures must be strictly followed. Moreover, for surfaces with complex geometries or deep recesses and protrusions, it is difficult to achieve a uniform coating using this method. In such cases, alternative techniques should be considered, or, under constrained budgetary conditions, manual spraying may be employed directly.
