Material requirements:
Large size silicone seal rings shall be made of silicone rubber materials that meet the requirements, and the materials shall have high temperature resistance, corrosion resistance, aging resistance and other characteristics.
The physical and chemical properties of silicone materials should also meet the requirements for use, such as tensile strength, tear strength, hardness, resilience, etc.
Silicone materials must comply with relevant safety standards to ensure that harmful substances are not released during the application of sealing rings.
Dimensional and geometric requirements:
The size of large-sized silicone sealing rings should meet the design requirements, and the size deviation should be within the allowable range of 1.
The geometric shape of the silicone sealing ring should be regular, and the surface should be smooth, free of defects such as bubbles and impurities.
The specific size specifications (such as inner diameter, outer diameter, and thickness) need to be selected according to the application scenario and requirements, and refer to relevant standard 2.
Surface quality requirements:
The surface of the silicone sealing ring should be smooth, free of scratches, cracks, and other defects.
The quality of the surface not only affects the appearance of the parts, but also directly affects their service life and performance.
Durability and reliability requirements:
Silicone sealing rings should be able to withstand certain conditions such as pressure, temperature, and chemical corrosion.
It should have high wear resistance and be able to maintain good sealing performance for a long time.
It shall be able to resist the effects of aging, fatigue and mechanical damage, with a high service life of 16.
Other special requirements:
According to specific application scenarios, special requirements such as thermal conductivity, electrical insulation performance, and flame retardancy of silicone sealing rings may also need to be considered.
In some special applications, there may be specific requirements for the hardness and elasticity of silicone sealing rings to ensure that they can effectively provide the required performance in sealing applications3.
In summary, the technical requirements for large-sized silicone sealing rings are multifaceted, requiring comprehensive consideration of multiple factors such as material, size, surface quality, durability, and reliability to ensure their performance and stability in practical applications.
