橡膠膜片是一種由橡膠材料制成的薄型彈性元件，在工業領域扮演著核心密封與傳動角色。其核心特性與用途如下： is a thin elastic component made of rubber material, playing a core sealing and transmission role in the industrial field. Its core features and uses are as follows:
Structure and Classification
Material type
Nitrile rubber (NBR): excellent oil resistance (such as fuel system sealing), strong wear resistance (hydraulic system piston sealing), suitable for temperatures ranging from -40 ℃ to 120 ℃.
Fluororubber (FKM): resistant to strong acids/alkalis and high temperatures (-20 ℃~200 ℃), used in chemical pipelines and aviation engines.
Silicone rubber (VMQ): Outstanding cold resistance (-60 ℃~200 ℃), good biocompatibility (medical equipment).
Ethylene propylene diene monomer (EPDM): heat-resistant and suitable for polar solvents (such as brake fluid).
Structural Design
Pure rubber type: excellent elasticity, economically applicable in low-pressure scenarios.
Clip type: Reinforced with nylon/polyester fibers, capable of withstanding up to 7 kilograms of pressure and strong deformation resistance (such as industrial valves).
Metal composite type: specialized for high-strength working conditions (such as high-pressure pumps).
Core functions and advantages
Precision control: Adjust flow rate, pressure, and liquid level difference (valve/regulating valve).
Dynamic sealing: prevents gas/liquid leakage, resistant to chemical corrosion (chemical containers).
Shock absorption transmission: converting mechanical motion (automatic follow-up device).
Lifespan and economy: With a flexible lifespan of over 2 million times, it has low cost and high reliability.
Application Fields
Key requirements for typical scenarios in the field
Automotive industry engine sealing, brake diaphragm oil resistance, high pressure
Medical equipment, respirator membrane, blood pressure monitor sealing, biological inertness, precise deformation
Fatigue resistance of pulse valve diaphragm for environmental protection equipment dust collector (30000 cycles)
Electronic appliances, mobile phone buttons, waterproof film, LCD screen sealing ultra-thin design (0.2mm)
Sealing of energy and chemical acid pipeline, anti-corrosion layer of reaction kettle, solvent resistance, high temperature stability
耐溶劑性、高溫穩定性
