Oil seals are typically made of rubber or synthetic materials that are resistant to oil, heat, and pressure. They are designed to withstand the harsh conditions within an engine or machinery, such as high temperatures and varying levels of pressure. The seal is usually placed in a housing or a groove in order to effectively seal the gap between two moving parts.
One common type of oil seal is the lip seal, which features a flexible lip that makes contact with the rotating shaft to create a tight seal. Lip seals are often used in automotive engines, gearboxes, and industrial pumps due to their effectiveness in preventing oil leaks. Another popular option is the mechanical seal, which uses a rotating element to maintain constant contact with the shaft, ensuring a reliable seal even at high speeds and pressures.
The sound-absorbing characteristics of mineral fiber ceiling boards are among their most significant benefits. These boards are designed to reduce noise levels in a space by absorbing sound waves, which limits echoes and reverberation. This makes them an ideal choice for areas such as classrooms, conference rooms, and healthcare facilities, where clear communication is essential. The Noise Reduction Coefficient (NRC) rating of these boards often falls between 0.5 to 0.9, indicating excellent sound absorption capabilities.
