Water Treatment in Resin Mold Maintenance: Sunlets Technology Provides Comprehensive Solutions
Water treatment plays a crucial role in the maintenance of resin molds used in high-pressure casting for sanitary ceramics. Proper water treatment not only ensures the longevity of the molds but also helps prevent contamination during production, ensuring product quality. Below are some key factors to consider in water treatment:
Typically, the slip used in sanitary ceramic production has a pH value lower than 7, making it acidic. To prevent the acidic water from corroding the resin molds, the wash water needs to be neutralized. Using appropriate neutralizing agents (such as sodium hydroxide or calcium hydroxide), the pH of the water should be adjusted to neutral (around pH 7) to ensure no adverse effects on the mold surface.
The slip may contain fine particles such as clay or sand, which can accumulate in the pores and surface of the resin molds, leading to mold wear or affecting the quality of the molded products. Therefore, when cleaning the molds, filtering devices or sedimentation tanks should be used to remove these particles from the water, ensuring the wash water is clean and preventing particles from re-entering the molds.
During production, chemical additives such as water-reducing agents and dispersants may be added to the slip. These additives will be washed out with the water during cleaning. If not properly treated, they could pollute the environment and even harm downstream water bodies. Therefore, suitable water treatment methods, such as chemical precipitation, adsorption, or membrane filtration, should be used to remove harmful additives from the slip, ensuring the water quality is compliant with environmental standards.
After prolonged use, small amounts of resin may detach from the molds. If this detached resin is not effectively treated, it may cause secondary contamination of the mold surface or affect subsequent production. A specialized resin recovery system should be considered to collect and treat the detached resin, preventing it from entering the water system.
Different types of resins react differently to water, making it essential to understand the type of resin used in the molds. The type of resin determines how the resin detaches and what potential contaminants may be present. When implementing water treatment, the characteristics of the resin should be considered to select the appropriate treatment method. For example, water treatment methods for epoxy resin and polyester resin may differ. Understanding the resin type and properties provided by the supplier helps develop a more targeted water treatment solution.
Water treatment is an essential part of maintaining resin molds. By properly neutralizing pH, removing slip particles, effectively treating additives and resin detachment, the lifespan of the molds can be extended, and the production process can run smoothly with consistent product quality. Furthermore, understanding the type of resin used in the molds and selecting suitable water treatment methods based on its characteristics will provide strong support for efficient production.
