Manufacturing method
of stabilizer
1. Introduction

In the field of chemical production raw materials, stabilizer is an important additive, mainly used to prevent or slow down the performance degradation of materials during processing, storage and use. There are many kinds of stabilizers and different manufacturing methods. This paper mainly discusses several common manufacturing methods of stabilizers.

2. stabilizer types and manufacturing methods

1. antioxidant

antioxidant is a kind of common stabilizer, mainly used to prevent the degradation of polymer materials due to oxidation. There are two main methods of manufacturing antioxidants: mixing method and reaction method. The

mixing method is to mix two or more kinds of antioxidant substances together and make antioxidants by physical mixing. This method is simple and easy, but the antioxidant performance is relatively low. The

reaction method combines different antioxidant substances through chemical reactions to generate new substances with higher antioxidant properties. The antioxidant prepared by this method has better performance, but the manufacturing process is relatively complicated.

2. light stabilizer

light stabilizer is mainly used to prevent the degradation of polymer materials due to ultraviolet radiation. The manufacturing method of light stabilizer mainly includes synthesis method and compounding method.

synthesis method is to synthesize new substances with light stability through chemical reaction. This method can produce light stabilizers with excellent performance, but the manufacturing process is cumbersome. The

compounding method is to mix a variety of substances with light stability together and make light stabilizers by physical mixing. This method is simple and easy, but the performance of the prepared light stabilizer is relatively low.

3. Heat stabilizer

heat stabilizer is mainly used to prevent polymer materials from degrading due to high temperature during processing. The manufacturing method of the heat stabilizer mainly includes a mixing method and a coating method. The

mixing method is to mix different kinds of heat stabilizer substances together and make the heat stabilizer by physical mixing. This method is simple and easy, but the performance of the prepared heat stabilizer may be reduced. The

coating method is to coat the surface of the heat stabilizer particles with a layer of other substances to improve the heat resistance of the heat stabilizer and the compatibility with polymer materials. The heat stabilizer prepared by this method has good performance, but the manufacturing process is relatively complicated.

3. stabilizer manufacturing process optimization

In order to improve the performance of the stabilizer and reduce production costs, it is necessary to optimize the manufacturing process. The following are some common manufacturing process optimization methods:

1. Using new raw materials: Selecting better performance and cheaper raw materials can improve the performance of stabilizers and reduce production costs.
2. Optimize the reaction conditions: By adjusting the reaction temperature, pressure, time and other conditions, the reaction efficiency and product purity can be improved, thereby improving the performance of the stabilizer.
3. The introduction of new technologies: the use of new technologies such as microwave synthesis, ultrasonic treatment, etc., can accelerate the reaction rate and improve the purity of the product, and further improve the performance of the stabilizer.
4. Strengthen production process control: By strengthening production process control, ensure stable and reliable product quality and improve production efficiency.

4. Conclusion There are various manufacturing methods of

stabilizers, and different manufacturing methods will have an important impact on the performance of stabilizers. In order to improve the performance of the stabilizer and reduce the production cost, the manufacturing process needs to be optimized. By selecting new raw materials, optimizing reaction conditions, introducing new technologies and strengthening production process control, the performance and quality of stabilizers can be further improved, providing better protection for chemical production.
