The production process and quality control of phenyl vinyl rubber are the key links to ensure its product quality and performance. The following is a detailed analysis of its production process and quality control:

1. Production process
The production process of phenyl vinyl rubber usually includes steps such as raw material preparation, polymerization reaction, product separation and purification.

Raw material preparation:
Select suitable monomers and initiators, such as methyl styrene, acrylic acid, etc., and ensure that their quality meets the requirements.
Determine the ratio and dosage of raw materials according to production requirements.
Polymerization reaction:
Carry out polymerization reaction in the reaction vessel, and control the reaction temperature, pressure and other conditions to ensure that the reaction proceeds smoothly and the target product obtains a high yield.
Polymerization reaction can be carried out by different methods, such as bulk polymerization, solution polymerization, etc. The specific choice depends on production requirements and raw material characteristics.
During the polymerization process, it is necessary to add an appropriate amount of solvents and additives to optimize the reaction conditions and improve the polymerization efficiency and product quality.
Product separation and purification:
After the polymerization reaction is completed, the product is extracted, separated and purified by appropriate methods, such as extraction, crystallization, distillation, etc.
Through these steps, impurities and unreacted monomers in the product can be removed, and the purity and quality of the product can be improved.
In addition, there are some specific production processes, such as the use of high-power high-shear vacuum stirring device to prepare high-viscosity phenyl methyl vinyl silicone rubber. This process solves the problem of heat and mass transfer through polymerization reaction under stirring and shearing, narrows the molecular weight distribution of the product, and improves the quality and production efficiency of the product.

2. Quality control
In the production process of phenyl vinyl raw rubber, quality control is an important link to ensure product quality and performance. The following are some common quality control measures:

Raw material quality control:
Strict quality inspection of raw materials to ensure that they meet production requirements.
Store and manage raw materials to prevent them from moisture, deterioration or contamination.
Polymerization reaction condition control:
Precisely control the temperature, pressure, time and other conditions of the polymerization reaction to ensure that the reaction proceeds smoothly and obtains high-quality products.
Regularly maintain and overhaul the reaction equipment to ensure its normal operation and safety.
Product quality inspection:
Quality inspection of the product, including indicators such as appearance, viscosity, purity, and molecular weight distribution.
Use advanced testing instruments and methods, such as gas chromatography, liquid chromatography, nuclear magnetic resonance, etc., to accurately analyze and measure the products.
Production environment control:
Keep the production environment clean and tidy to prevent dust, impurities and other pollutants from entering the production process and products.
Properly handle waste in the production process to prevent it from causing harm to the environment and human body.
Quality management system:
Establish a complete quality management system, including quality management system, quality inspection process, quality improvement measures, etc.
Regularly review and evaluate the quality management system to ensure its effectiveness and adaptability.

In summary, the production process and quality control of phenyl vinyl raw rubber are the key links to ensure its product quality and performance. High-quality phenyl vinyl raw rubber products can be produced by selecting suitable raw materials, accurately controlling polymerization reaction conditions, strictly conducting product quality inspections, and keeping the production environment clean and tidy.
