Cooling towers operate continuously, leading to the potential for scale buildup, corrosion, and microbiological growth in the water system. These issues can cause substantial problems, including reduced heat exchange efficiency, increased energy costs, and equipment failure. Therefore, water treatment is critical to mitigating these risks. The main objectives of water treatment are to control scale formation, prevent corrosion, inhibit biofilm development, and ensure the overall efficiency of the cooling system.
Colorants, including pigments and dyes, enhance the aesthetics of plastic products. They can provide vibrant colors, improve opaqueness, and even impart special effects such as metallic or pearlescent finishes. The choice of colorant depends on the desired application and the properties of the base polymer. For example, certain pigments are designed to withstand UV light to prevent fading and maintain the product's appearance over time.
