Industrial Descaling refers to the process of removing inorganic scale (such as calcium carbonate, calcium sulfate, iron oxide, silica scale, etc.) or organic scale (such as oil contamination, microbial biofilms) that has accumulated in industrial equipment, pipelines, and heat exchange systems due to prolonged operation.
These deposits typically originate from calcium and magnesium ions in hard water, corrosion products in cooling water or steam systems, and impurities in process fluids. They adhere to pipe walls or equipment surfaces, leading to reduced heat transfer efficiency, restricted flow, accelerated corrosion, and increased energy consumption.
These products are chemical descaling additives that do not directly react with scale deposits in industrial cleaning systems. Instead, they enhance cleaning efficiency by improving the descaling environment and the performance of cleaning solutions:
Emulsifier E1300 series and E1000 series primarily function as surfactants. They significantly reduce the surface tension of cleaning solutions, thereby enhancing the wetting and penetration capabilities of acid solutions against deposits such as calcium carbonate or iron oxide. This accelerates reaction rates and reduces chemical consumption. Polyethylene glycol oleate excels in complex environments where oil and scale coexist. It emulsifies and disperses grease adhering to equipment surfaces, enabling acid solutions to effectively contact and dissolve scale layers. Polyethylene glycol laurate focuses more on dispersion and stabilization, keeping detached particles in suspension to prevent redeposition. Its low-foaming properties make it suitable for circulating cleaning systems. Emulsifier O series is particularly effective against scale accompanied by oil deposits. By emulsifying oil layers it prevents them from shielding metal surfaces, allowing descaling agents to function fully. Emulsifier LAE series combines penetration and dispersion properties, making it especially common in applications requiring rapid, efficient cleaning (e.g., CIP systems for food or pharmaceutical equipment). Collectively, these additives synergistically complement each other through “wetting, penetration, emulsification, and dispersion,” making the chemical descaling process more thorough, efficient, and controllable.
