Die-casting release agent is a water-based substance used between molds and finished products. It mainly prevents products from sticking to molds and serves as a type of production auxiliary that facilitates demolding. Due to the rapid development of the die-casting industry, the usage of release agents has increased significantly. Youteng Environmental Protection independently develops and produces release agent recovery equipment dedicated to release agent recovery, and also has certain expertise in the selection of release agents.
Release agents are mainly divided into three categories: inorganic substances, organic substances, and polymers. Inorganic release agents, such as compounds formulated with talcum powder, mica powder, kaolin, white clay and other main components, are mainly used as release agents for preventing adhesion of rubber sheets and semi-finished products in rubber processing. Release agents usually come in powder, semi-solid and liquid forms. Powder and semi-solid release agents can be applied to the mold surface with a brush or by hand like wax. Liquid release agents can be applied to the mold surface using tools such as sprayers or brushes to form a separation film. Liquid release agents are mainly sprayed, and most of them are packaged in metal spray cans. Die-casting machines use water-based spray release agents. Since metal spray cans have good sealing performance, they can prevent the release agent from oxidizing or mixing with impurities, ensuring the purity of the release agent when leaving the factory. Large injection molding equipment is installed indoors, where the ambient temperature changes little, so it has no impact on the use of spray release agents.
In the selection of release agents, economy is an important factor that cannot be ignored. Low-quality release agents can cause cracking and wrinkling on the product surface, affect the product appearance and the service life of the mold, and bring environmental pollution. Choosing high-quality spray release agents is more expensive, but the comprehensive economic benefits are high. To prevent environmental pollution, it is necessary to select release agents that are not easy to burn and have low odor and toxicity.
In summary, the key points for selecting a release agent are:
1. It has heat resistance and does not carbonize or decompose when heated.
2. It does not affect the secondary processing performance of die-casting.
3. It has excellent release properties; for spray release agents, the surface tension should be between 17 and 23 N/m.
4. It has stable chemical properties and does not undergo chemical reactions with the molded products.
5. It does not corrode molds, does not contaminate products, and has low odor and toxicity.
