In modern industrial production, electroplating is a common and important surface treatment process. Whether it is hardware, auto parts, or electronic product shells, electroplating can improve the appearance, corrosion resistance and service life of the product. However, during the processing, storage or transportation of metals, they are often stained with various lubricants, hand sweat, dust and other pollutants. If these impurities are not removed cleanly, they will seriously affect the subsequent electroplating quality, such as causing the coating to be poorly adhered, bubbling, and shedding. It is necessary to select a suitable electroplating pretreatment degreasing agent for cleaning.
Application of electroplating pretreatment degreasing agent
Electroplating pretreatment degreasing agent products do not contain phosphorus and heavy metals, are safe and environmentally friendly, and do not produce irritating odors during use; cathode or anode electrolytic degreasing is suitable, degreasing is fast, the product has low foam, good water washability, strong cleaning ability, and quickly removes carbon deposits and putty. The surface of the workpiece treated with this product is clean and residue-free, which can effectively activate the surface of the workpiece and enhance the bonding strength of the coating; the product does not agglomerate, is easily soluble in water, has the function of inhibiting alkaline mist, and has low or no corrosion to the metal surface; the product has a long service life. The product is suitable for degreasing metals such as steel, copper and alloys, but not for non-ferrous metals and non-metallic materials such as aluminum.
In order to improve the degreasing efficiency, many companies now use ultrasonic cleaning equipment. Ultrasonic cleaning is an efficient physical cleaning method. It forms countless tiny bubbles in the liquid through high-frequency sound waves. These bubbles will produce a strong impact when they burst, "shaking" the oil stains on the metal surface.
Adding the electroplating pre-treatment degreasing agent to the ultrasonic cleaning tank is better than traditional manual brushing, especially suitable for parts with complex shapes and dead corners. Ultrasonic waves can enter tiny gaps and clean places that ordinary cleaning cannot reach. This method not only improves cleaning efficiency, but also saves labor and reduces product defective rates.
However, during use, it is also necessary to pay attention to controlling the cleaning time, temperature and degreasing agent concentration. The temperature is generally controlled at 50-80℃, which is ideal, which can help the degreasing agent to play a better effect. It is a very mature and efficient method in current industrial cleaning. It can not only greatly improve the quality of electroplating, but also help enterprises improve production efficiency and reduce costs. It is an indispensable part of modern metal processing.
