Styrene-the manufacturing method
of driving materials
1. Introduction

Styrene is an important organic chemical raw material, widely used in the production of plastics, synthetic rubber, synthetic fibers and other fields. The starting material is in chemical production, used to start equipment, cleaning pipes and other special purpose materials. Therefore, it is of great significance to study the manufacturing method of styrene-starting material for improving chemical production efficiency and reducing production cost.

2. The manufacturing method of styrene-starting material

1. Raw material preparation

The manufacturing of styrene-starting material needs to prepare the following raw materials: styrene, initiator, dispersant, stabilizer, etc. Among them, styrene is the main raw material, the initiator is used to initiate the polymerization reaction, the dispersant is used to improve the dispersion of the product, and the stabilizer is used to prevent the product from aging during storage and use.

2. polymerization reaction

styrene, initiator, dispersant, stabilizer and other raw materials are added to the polymerization kettle according to a certain proportion, and the polymerization reaction is carried out at a certain temperature and pressure. It is necessary to control the reaction speed and temperature during the polymerization reaction to ensure the quality and yield of the product.

3. Post-treatment
After the
polymerization reaction is completed, post-treatment is required, including cooling, degassing, filtration, etc., to obtain the final styrene-starting material product. In the post-processing process, it is necessary to pay attention to the stability of the product to avoid problems in the processing and use of the product.

3. Styrene -

in the process of starting material manufacturing 1. Raw material quality control

Styrene-starting material manufacturing needs to strictly control the quality of raw materials to ensure that the purity and moisture of raw materials meet the production requirements, so as to avoid adverse effects on product quality and output.

2. Control
of polymerization conditions
polymerization is a key step in the manufacturing process of styrene-starting materials. It is necessary to strictly control the reaction temperature and pressure to ensure the quality and output of products. At the same time, it is necessary to pay attention to the by-products and wastes that may be generated during the polymerization reaction, and take reasonable treatment measures to avoid adverse effects on the environment and production.

3. Control
of post-treatment process
post-treatment process is an important link in the manufacturing process of styrene-starting materials. It is necessary to strictly control the operating conditions and parameters of cooling, degassing, filtering and other steps to ensure the quality and stability of the product. At the same time, it is necessary to pay attention to the waste and wastewater that may be generated in the post-treatment process, and take reasonable treatment measures to avoid adverse effects on the environment and production.

4. Conclusion The manufacturing method of

styrene-start-up material involves many links and process steps, and it is necessary to strictly control the quality of raw materials, polymerization reaction conditions and operating parameters and conditions of the post-treatment process to ensure product quality and yield. At the same time, it is necessary to pay attention to the waste and wastewater that may be generated in the production process, and take reasonable treatment measures to protect the environment and production safety.
