With the rapid advancement of science and technology, an increasing number of technological products have become integral to everyday life and are even widely employed in industrial production. In the coating industry, non‑curing spray machines have gained widespread adoption. Next, I will outline 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 are primarily responsible for preparing workpieces, loading and unloading equipment, and monitoring adjustments—eliminating direct contact with the coating during operation and significantly reducing physical labor. Moreover, during the spraying process, non‑curing spray machines produce oil mist that spreads far less than in air‑pressure or conventional spray applications, thereby minimizing workplace contamination and safeguarding 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 integrity and shortens the service life of the project. Using a non‑curing spray machine yields high paint utilization. During application, 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 a high‑voltage electrostatic field, ensuring relatively uniform distribution during spraying. 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 a fire. Therefore, reliable fire‑ and explosion‑proof measures must be in place, and strict adherence to safety operating procedures is essential. Furthermore, for surfaces with complex geometries or deep recesses and protrusions, it is difficult to achieve a uniform coating using this technique. In such cases, alternative methods should be considered, or, under constrained budgetary conditions, manual spraying may be employed directly.
