rubber diaphragm Analysis of the Characteristics and Applications of Fabric-Reinforced Rubber Diaphragms
A. Characteristics
Fabric-reinforced rubber diaphragms are components made by combining rubber with fabrics such as nylon, polyester, and aramid. They combine the elasticity of rubber with the strength of fabrics. The core features are as follows:
1. Structural and Performance Synergy
The fabric layer (such as nylon fabric) enhances tear resistance and durability under pressure and deformation.
The rubber matrix ensures elastic deformation capability, achieving precise conversion of “pressure – displacement/force”.
2. Environmental Adaptability
Wide temperature range (such as -20°C to +250°C, with some scenarios covering an even broader range).
Strong resistance to media (compatible with oil, acid, alkali, corrosive gases, etc. Different rubber matrices can be targeted to enhance resistance, such as nitrile rubber for oil resistance and fluorine rubber for strong corrosion resistance).
3. Function and Reliability
No hysteresis loss, rapid response (for example, in pneumatic valves, diaphragms need to act quickly in response to electromagnetic signals).
Small permanent deformation after compression, maintaining sealing and transmission accuracy over long-term use.
Resistant to aging, oil, acid, and alkali, ensuring long service life (in some scenarios, it can achieve millions of extension and contraction cycles).
4. Manufacturing Process and Customization
Mature manufacturing processes (such as rubber-metal bonding, precision molding), with thickness and size customizable (such as thickness from 0.1 to 5mm, outer diameter covering Φ30 to 600mm); surface roughness, thickness tolerance, and other parameters are controllable, meeting the requirements of precision equipment.
B. Applications
Fabric-reinforced rubber diaphragms, with core functions such as “sealing, transmission, and pressure regulation”, are widely used in fluid control, industrial automation, automotive, instrumentation, aerospace, and many other fields.
