Advantages of low-odor reaction catalysts in electronic product shell manufacturing: the choice of both environmental protection and aesthetics

Catalytic selection for electronic product shell manufacturing: Thoughts on both environmental protection and aesthetics

In today’s era of rapid technological development, the popularity of electronic products has become an indispensable part of our lives. From smartphones to laptops to smart home devices, these products not only need to have powerful functions, but their appearance design and material choice are also increasingly valued by consumers. Especially in the manufacturing process of electronic product shells, how to balance environmental protection and aesthetics has become an important topic.

Traditionally, many manufacturers tend to use catalysts with high levels of volatile organic compounds (VOCs) to accelerate the curing process of materials. However, although this practice improves productivity, it has an important impact on the environment and human health. As global awareness of environmental protection increases, more and more companies are seeking more environmentally friendly, low-odor reactive catalysts as alternatives.

The advantage of low-odor reaction catalysts is that they not only significantly reduce the emission of harmful gases, but also effectively improve the surface quality of the final product.

Before we have a deeper understanding of the application of low-odor reaction catalysts in the manufacturing of electronic product shells, we need to master its basic working principles and main categories. Catalysts are substances that can change the rate of chemical reactions without being consumed, while low-odor reaction catalysts are further optimized on this basis to reduce the generation of adverse by-products, especially those that have potential for human health and the environment. Hazardous volatile organic compounds (VOCs).

Working Principle

The core function of low-odor reaction catalysts is to accelerate or regulate the progress of specific chemical reactions. Taking polyurethane materials as an example, such catalysts usually form a stable polymer network structure by promoting the reaction between isocyanate groups and polyols. During this process, the catalyst not only increases the reaction speed, but also ensures that the reaction path is more accurate, thereby reducing unnecessary side reactions. This means that the final product not only forms faster, but also has a more uniform internal structure.Higher surface quality.

Specifically, the mechanism of action of a catalyst can be divided into the following steps:

Activation reactants: The catalyst makes the reaction easier to start by reducing the activation energy required for the reaction.
Directional guided reaction paths: By selectively accelerating certain reaction steps, avoiding the production of unwanted by-products.
Stable intermediate state: During the reaction process, the catalyst can stabilize intermediate molecules to prevent them from decomposing or adverse reactions with other components.
Control reaction rate: Through precise control of the reaction rate, ensure that the material performance reaches an optimal state.
