In our daily life, whether it is home or industrial environment, rubber seals play a vital role, and undertake the important tasks of maintaining sealing, preventing leakage, protecting equipment and personal safety.
Characteristics and materials of rubber seals:
1. Elasticity and elasticity: Rubber seals have excellent elasticity and elasticity, can maintain shape under pressure and adapt to interfaces of various sizes. This property enables them to play a good sealing effect in equipment of various shapes and sizes.
2. Sealing performance: Rubber seals have excellent sealing performance and can effectively prevent the leakage of liquids and gases. In high pressure, vacuum or humid environments, rubber seals can still maintain their stability to ensure the normal operation of equipment and systems.
3. Chemical corrosion resistance: Many industrial processes involve corrosive substances, and rubber seals have good chemical corrosion resistance. This allows it to work stably for a long time in corrosive environments such as acids and alkalis.
4. High and low temperature resistance: High and low temperature environments place high demands on sealing materials. Rubber sealing rings are not easy to soften at high temperatures and are not easy to harden at low temperatures, so they can maintain good sealing performance under extreme temperature conditions.
5. Anti-aging: Rubber sealing rings have good anti-aging properties and can maintain their original elasticity and sealing performance even after long-term use. This allows it to always maintain good performance during long-term use.
Application scope of rubber sealing rings:
① Petroleum and chemical industry: In the petroleum and chemical industry, rubber sealing rings are widely used in various equipment and systems, such as pipeline connections, reactors, centrifuges, etc. These equipment operate under high temperature, high pressure, and corrosive environments, and have high requirements for sealing performance. Rubber sealing rings can provide reliable sealing protection to ensure safety and efficiency in the production process.
② Power and energy: In the field of power and energy, rubber sealing rings are used in high-voltage electrical appliances, nuclear energy equipment, wind power generation devices, etc. These equipment have high requirements for sealing performance to prevent high-voltage arcs, leakage of radioactive materials or gas leakage. Rubber sealing rings can provide reliable sealing protection to ensure the safe operation of equipment.
③ Rail transit: In the field of rail transit, rubber seals are widely used in the hydraulic system, pneumatic system and other equipment with high sealing requirements of vehicles. These equipment need to maintain stable and reliable sealing performance when running at high speed to prevent gas leakage, liquid leakage or damage to the equipment by the external environment. Rubber seals can provide reliable sealing protection to ensure the safe and efficient operation of vehicles.
④ Construction and building materials: In the field of construction and building materials, rubber seals are used for waterproofing projects, door and window sealing, wall sound insulation, etc. These applications require rubber materials with good sealing performance, strong weather resistance and good anti-aging performance to improve the performance and life of the building. For example, in waterproofing projects, rubber seals can effectively prevent moisture penetration and ensure the waterproof performance of buildings.
⑤ Medical and pharmaceutical: In the field of medical and pharmaceutical, rubber seals are widely used in infusion equipment, drug packaging, medical devices, etc. These equipment require highly clean and reliable sealing performance to prevent drug contamination or gas leakage. Rubber seals can provide reliable sealing protection to ensure the safe transmission and use of drugs and blood.
⑥ Electronics and semiconductors: In the manufacturing process of electronics and semiconductors, rubber seals are used to prevent gas and liquid leakage and protect sensitive electronic equipment. These devices have high requirements for sealing performance to prevent damage to the equipment from external environments such as dust and moisture. Rubber seals can provide reliable sealing protection to ensure the stability and reliability of the equipment.
⑦ Environmental protection and water treatment: In the field of environmental protection and water treatment, rubber seals are widely used in water treatment equipment, waste gas treatment devices, etc. These equipment require highly reliable sealing performance to prevent gas leakage, liquid leakage or damage to the equipment from the external environment. Rubber seals can provide reliable sealing protection to ensure the environmental protection performance of the equipment and the water quality treatment effect.
⑧ Food and beverages: In the food and beverage industry, rubber seals are widely used in various food processing and packaging equipment. For example, a rubber seal is required between the bottle neck and the bottle cap on the filling production line to ensure the accurate filling of liquid food; in the packaging machine, the rubber seal can ensure the sealing of the packaging material to prevent food contamination or oxygen from entering.
⑨ Aerospace: In the field of aerospace, rubber seals are widely used in various aircraft structures and engine components. For example, the contact surface between the aircraft tire and the wheel hub requires a rubber seal to ensure the airtightness of the aircraft; the hydraulic system and air pressure system of the engine also require rubber seals to maintain the pressure balance of the system.
⑩ New energy: In the field of new energy, rubber seals are used in the manufacture of equipment such as solar panels and wind power generation devices. For example, the rubber seals in solar panels can protect the panels from environmental factors and ensure the stability of power output; in wind power generation devices, rubber seals are used for lubrication and sealing of bearings, gearboxes and other parts, improve the transmission efficiency of the equipment and prevent equipment damage caused by friction heat.
Selection and use of rubber seals:
1. Selection: Select a suitable rubber seal according to the use environment, working pressure, temperature and other conditions. When selecting, you need to consider parameters such as material, structure and size. For example, for high temperature environments, you need to choose a silicone rubber material with good high temperature resistance; for high pressure environments, you need to choose a polyurethane rubber material with good pressure resistance. At the same time, it is also necessary to select the appropriate structure and size according to actual needs.
2. Use: Correct installation and use of rubber sealing rings are the key to ensuring their sealing performance. During installation, care should be taken to avoid excessive stretching or compression to avoid damaging the sealing ring. At the same time, care should be taken to keep its surface clean and smooth to avoid the impact of impurities and wear on its sealing performance. During use, the wear should be checked regularly and replaced in time if damage is found.
