The manufacturing method
of PTFE suspended medium particles
1. Introduction

Polytetrafluoroethylene (PTFE) is a high-performance fluoroplastic with excellent chemical corrosion resistance, high temperature resistance, low friction coefficient and other characteristics. It is widely used in chemical industry, machinery, electronics, medicine and other fields. PTFE suspension medium particle is an important raw material for manufacturing high-performance PTFE products, and its manufacturing method has an important influence on the performance and quality of the product. This article will introduce the manufacturing method of PTFE suspended medium particles.

2. Manufacturing Methods

1. Ingredients

PTFE suspension particles in the main raw material is PTFE resin, additives including dispersants, stabilizers, lubricants and so on. According to a certain proportion of the raw materials into the high-speed mixer, fully mixed evenly.

2. Emulsification

The ingredients are added to an emulsifying machine, a certain amount of water is added, and the PTFE resin is dispersed into minute particles by high-speed stirring to form an oil-in-water emulsion. During the emulsification process, the stirring speed and time need to be controlled to ensure the uniformity and stability of the particles.

3. Coagulating
PTFE particles are coagulated into larger particles
adding a coagulant to the emulsion. The type and amount of the coagulant need to be adjusted according to the actual situation to ensure that the size and shape of the particles meet the requirements.

4. Washing

Wash the agglomerated particles with water to remove impurities and residues on the surface. The water needs to be changed several times during the washing process to ensure the purity of the particles.

5. Drying

The washed granules were put into a drying oven and dried at an appropriate temperature to obtain PTFE suspension medium particles. It is necessary to control the temperature and time during the drying process to prevent the deformation and deterioration of the particles.
Precautions for
3.

1. Strictly control the quality and proportion of raw materials to ensure the performance and stability of the product.

2. During the emulsification process, it is necessary to maintain an appropriate stirring speed and time to avoid too large or too small particles.

3. The type and amount of the coagulant need to be adjusted according to the actual situation to ensure that the size and shape of the particles meet the requirements.

4. The water needs to be changed several times during the washing process to ensure the purity of the particles.

5. The temperature and time need to be controlled during the drying process to prevent particle deformation and deterioration. Summary of

4. The manufacturing method of

PTFE suspension particles includes the steps of batching, emulsification, coagulation, washing and drying. In the manufacturing process, it is necessary to strictly control the process parameters of each step to ensure the performance and quality of the product. At the same time, it is necessary to pay attention to safety and environmental protection and comply with relevant laws, regulations and standards. By mastering the manufacturing method of PTFE suspended medium particles, it can improve product quality and production efficiency, reduce costs and enhance market competitiveness for enterprises.
