Rubber seals 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 seals are used in high-voltage appliances, nuclear energy equipment, wind power plants and so on. These devices have high requirements for sealing performance to prevent high-voltage arcing, radioactive material leakage or gas leakage. The rubber sealing ring can provide reliable sealing protection to ensure the safe operation of the equipment. ¢Û Rail transit: In the field of rail transit, rubber seals are widely used in vehicle hydraulic systems, pneumatic systems and other equipment with high sealing requirements. These devices need to maintain stable and reliable sealing performance when operating at high speed to prevent gas leakage, liquid leakage or external environment damage to the equipment. Rubber seals provide reliable sealing protection to ensure safe and efficient operation of the vehicle. Construction and building materials: In the field of construction and building materials, rubber seals are used for waterproof engineering, door and window sealing, wall sound insulation and so on. These applications require rubber materials with good sealing performance, strong weather resistance and good aging resistance to improve the service performance and life of the building. For example, in waterproof projects, rubber seals can effectively prevent water penetration and ensure the waterproof performance of the building. Medical and pharmaceutical: In the medical and pharmaceutical fields, rubber seals are widely used in infusion equipment, pharmaceutical packaging, medical equipment and so on. These devices require a high degree of cleanliness and reliable sealing performance to prevent drug contamination or gas leakage. The rubber seal can provide reliable sealing protection to ensure the safe transmission and use of drugs and blood. Electronics and semiconductors: In the electronics and semiconductor manufacturing process, rubber seals are used to prevent gas and liquid leakage, as well as to protect sensitive electronic equipment. These devices have high requirements for sealing performance to prevent dust, moisture and other external environment damage to the equipment. The rubber sealing ring can provide reliable sealing protection to ensure the stability and reliability of the equipment. 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 equipment and so on. These devices require highly reliable sealing performance to prevent gas leakage, liquid leakage or damage to the equipment from the external environment. The rubber sealing ring can provide reliable sealing protection to ensure the environmental performance and water quality treatment effect of the equipment. Food and beverage: In the food and beverage industry, rubber seals are widely used in a variety of food processing and packaging equipment. For example, a rubber seal is required between the bottle neck and the bottle cap on the filling line to ensure 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 entry. Aerospace: In the aerospace field, 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 rubber seals to ensure the airtightness of the aircraft; The hydraulic and air pressure systems of the engine also require rubber seals to maintain the pressure balance of the system. ¢â New energy: In the field of new energy, rubber seals are used in the manufacturing of solar panels, wind power plants and other equipment. For example, rubber seals in solar panels 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, gear boxes and other parts to improve the transmission efficiency of the equipment and prevent equipment damage caused by friction heat.

In the selection, need to consider its material, structural form and size and other parameters. For example, for high temperature environment, it is necessary to choose silicone rubber material with good high temperature resistance; For high pressure environments, it is necessary to choose polyurethane rubber materials with good compressive properties. At the same time, it is also necessary to choose the appropriate structural form and size according to the actual demand. 2. Use: The correct installation and use of rubber sealing ring is the key to ensure its sealing performance. During installation, care should be taken to avoid excessive stretching or compression, so as not to damage the sealing ring. At the same time, it is also necessary to pay attention to keep its surface clean and smooth to avoid the impact of impurities and wear on its sealing performance. During use, it should be regularly checked for wear, and replaced in time if damage is found. Fourth, the production process and quality control of rubber seals -- A. Production process: The production process of rubber sealing ring mainly includes mixing, calendering, vulcanization and other links. Mixing is to mix all kinds of raw materials evenly; Calendering is to press the mixed rubber material into a certain shape; Vulcanization is to cross-link the rolled rubber at a certain temperature and pressure to form rubber products with elastic and sealing properties. B. Quality control: In order to ensure that the quality and performance of rubber seals meet the requirements, strict quality control is required. It includes the quality control of raw materials, the control of production process and the inspection of finished products. The quality of raw materials directly affects the performance and quality of rubber products, so it is necessary to strictly select and control raw materials; The control of production process is an important link to ensure product quality. The inspection of the finished product is an important means to ensure that the quality of the product meets the requirements. Fifth, the future development and trend of rubber seals -- With the progress of science and technology and the development of society, the performance requirements of rubber seals are becoming higher and higher. In the future, rubber seals will develop in the direction of high performance, environmental protection and intelligence. The new synthetic rubber material will improve its temperature, pressure and corrosion resistance. The biodegradable rubber material is conducive to environmental protection; The intelligent rubber sealing ring can monitor the operating status of the equipment in real time through sensors and other devices, providing important information for the maintenance of the equipment. At the same time, with the development and application of automation and intelligent manufacturing technology, it will further promote the automation and intelligent level of rubber seal manufacturing. The development of rubber seals in the future will pay more attention to the improvement of its functionality and environmental protection, and will continue to expand its application field and market space.
