In various types of mechanical equipment and daily necessities, noise problems often cause trouble for people, and the rubber coating on the surface of anti-collision screws plays a very critical role in preventing noise, and has excellent performance in many aspects.
The rubber coating has excellent buffering performance. When the parts where the screws are located move relative to each other or are impacted by external forces, the rubber coating can effectively absorb the energy generated by the collision. Compared with the direct collision between metal and metal, the elasticity of rubber causes it to deform at the moment of contact, converting the rigid collision that may originally produce sharp and harsh noise into a relatively soft extrusion process, thereby greatly reducing the noise intensity at the moment of collision. For example, in the assembly of furniture, if anti-collision screws with rubber coating are used, the noise generated by the screw connection parts will be significantly reduced when opening and closing drawers and moving tables and chairs in daily life, avoiding annoying creaking and collision sounds.
Its excellent damping characteristics are also an important factor in noise reduction. The rubber coating can suppress the transmission of vibration between the screws and the connected parts, and reduce the resonance caused by vibration. Resonance often greatly amplifies noise, while the rubber coating gradually consumes the vibration energy through its own viscoelasticity, making it impossible for the noise to continue to increase and spread within the system. For example, in some automation equipment in industrial production, there are many screw connection points inside. If ordinary screws are used, the vibration noise during the operation of the equipment will be very large, while the rubber coating of the anti-collision screws can effectively "calm" these vibration noises, making the equipment run more quietly and smoothly.
The rubber coating also plays a good sealing role. It can fill the tiny gaps between the screws and the mounting holes to prevent whistling or howling sounds generated when air flows through these gaps. This sealing effect is particularly important in some equipment or pipe connections with airflow. For example, if the pipe connection screws in the ventilation system are rubber-coated, high-frequency noise caused by air leakage can be effectively avoided, ensuring that the ventilation system runs quietly and efficiently.
From an acoustic point of view, the porous structure and viscoelasticity inside the rubber coating can absorb and scatter sound waves. When the noise wave propagates to the surface of the rubber coating, part of the sound wave energy is absorbed by the pores in the coating and converted into heat energy for dissipation, while the other part is scattered in all directions, reducing the propagation intensity of the noise in a specific direction. This allows the rubber-coated anti-collision screw to suppress noise in a wider frequency range, and both low-frequency humming and high-frequency squeaking can be alleviated to a certain extent.
In short, the rubber coating on the surface of the anti-collision screw shows excellent performance in preventing noise generation through buffering, damping, sealing, absorption and scattering of sound waves, etc., which is of great significance in creating a quiet and comfortable environment in both industrial production and daily life.
