PTFE Gasket Introduction
PTFE gaskets are gaskets made of polytetrafluoroethylene as the main material. Polytetrafluoroethylene, also known as PTFE, is a polymer material with very special properties, such as excellent chemical stability, insulation, non-toxicity, corrosion resistance, heat resistance, high compressive strength, and anti-adhesion. As a result, PTFE gaskets are widely used in various industrial and aerospace applications for their outstanding performance.
Advantages of PTFE gaskets
1. High pressure resistance: PTFE gaskets can withstand extremely high pressure and maintain stable performance for a long time without being deformed or bent due to pressure increase.
2. Excellent corrosion resistance: PTFE gaskets have good resistance to many strong corrosive media, and can effectively protect the equipment from the effects of corrosion.
3. High temperature resistance: PTFE gaskets at high temperatures can still maintain the basic performance of its materials, in 800 ℃ can be stable operation.
4. Non-toxicity: PTFE gasket is a non-toxic and harmless material, which will not harm the equipment and human body.
5. Excellent insulation: PTFE gaskets have very good insulation properties and can effectively protect equipment and personnel from the hazards of electric shock.
6. Anti-adhesion: PTFE gaskets have a very smooth surface and will not be deformed by humidity and other factors, thus ensuring the safety of the equipment.
7. Abrasion resistance: PTFE gaskets are less abrasive, which can effectively extend the service life of the equipment.
Application fields of PTFE gaskets
1. Petrochemical field: PTFE gaskets are widely used in petrochemical industry, such as valves, seals, chemical equipment and so on.
2. Food industry: PTFE gasket material is extremely pure, without any harmful substances, with food contact is no problem, therefore, in the food and pharmaceutical industry has also been widely used.
3. Medical device field: PTFE gaskets can be used in the field of medical devices, such as artificial heart, as a film.
4. Mechanical manufacturing field: PTFE gaskets can be used in precision instruments, attached parts of the mechanical part of the small joints as well as electrical devices between the magnetic induction joints and so on.
5. Aerospace field: PTFE gaskets can be used for sealing devices of aircraft engines, sealing gaskets of wing parts, joints between aircraft axles and so on.
Production process of PTFE gaskets
The production process of PTFE gasket includes raw material preparation, batching, powder making, molding, sintering, processing and inspection.
The selection of raw materials first requires the collection of raw PTFE resin powder to ensure its purity, particle size, density and other requirements. Then batching is carried out, aiming to ensure the uniform mixing of various substances to ensure the stability of the product material.
Subsequently, powdering is carried out, and the resin powder is preheated, dried, and rice milled to make fine micro-powder.
Then molding is carried out, under the environment of high pressure, the micro-powder will be molded into various shapes of dietary gaskets according to the requirements.
Next, sintering is carried out, where the molded shims are baked in a specific sintering oven to uniformly dry and harden both internally and externally.
Finally, processing and inspection are carried out, with different degrees of processing according to product models and specifications, and strict inspection is carried out to ensure the quality and usability of the products.
Summarize
As an excellent polymer material with high pressure resistance, excellent corrosion resistance, high temperature resistance, non-toxicity, excellent insulation, anti-adhesion, wear resistance, etc., PTFE gasket is widely used in industrial and aviation fields. Therefore, the production process of PTFE gaskets is also becoming more and more important, which can ensure the quality of its products and the performance of its use, and improve the production efficiency and economic benefits.
