Manufacturing method of PTFE suspended fine particles
I. Introduction
Polytetrafluoroethylene (PTFE) is a polymer material with excellent properties, widely used in chemical, mechanical, electronic, medical and other fields. PTFE suspended fine particles, as a kind of important form of PTFE, are widely used due to its unique properties, such as excellent corrosion resistance, low coefficient of friction, high electrical insulation and thermal stability. widely used. In this paper, the manufacturing method of PTFE suspended fine particles will be introduced in detail.
II. Materials and Methods
1. Materials
The main raw material is PTFE resin, and the auxiliary materials include dispersant, stabilizer, initiator and so on.
2. Equipment
The equipment needed includes mixing kettle, polymerization kettle, extruder, grinder and so on.
3. Manufacturing steps
1. Ingredients
Add PTFE resin, dispersant, stabilizer, etc. to the mixing kettle according to a certain proportion, and mix well.
2. Polymerization
Add the ingredients into the polymerization kettle and carry out the polymerization reaction under certain temperature and pressure to produce PTFE particles.
3. Extrusion
Polymerized PTFE granules are added to the extruder, and PTFE filaments are formed by the action of the extruder.
4. Grinding
Add the extruded PTFE filaments into the grinder and grind them to obtain PTFE suspended fine particles.
4. Precautions
1. In the process of dosing, ensure the purity and accurate proportion of raw materials in order to avoid the impact on product quality.
2. In the polymerization reaction, the temperature and pressure should be strictly controlled to ensure the smooth progress of the reaction.
3. In the extrusion and grinding process, the process parameters should be adjusted according to the equipment condition and product requirements to ensure product quality and productivity.
V. RESULTS AND DISCUSSION
Through the above manufacturing steps, we can get high quality PTFE suspension fines. These fine particles have good corrosion resistance, low coefficient of friction, high electrical insulation, thermal stability and other advantages, which can be used to manufacture a variety of high-performance chemical products.
During the manufacturing process, we need to pay attention to controlling each process parameter to ensure product quality and production efficiency. At the same time, we also need to constantly explore new manufacturing processes and technologies to improve the performance and application range of PTFE suspended fine particles.
VI.Conclusion
In conclusion, the manufacture of PTFE suspension pellets requires strict control of each process parameter to ensure product quality and production efficiency. Through continuous exploration and practice, we can continue to improve the performance and application range of PTFE suspended fine particles, and make greater contributions to the development of the chemical industry.
