Rubber O-rings are stored for a long time as spare parts. In order to avoid the physical and chemical properties of rubber O-rings being affected by external factors and damage to the elastomer, the following rules should be followed during storage
1. Cleaning: As needed, the seals can be cleaned with soap and water. However, water should not come into contact with fiber reinforced seals, rubber-to-metal bonded seals, and AU material seals. Disinfectants, organic solvents and tools with sharp edges should not be used. Cleaned seals should be air-dried at room temperature away from heat sources.
2. Radiation: Avoid ionizing radiation damage to seals.
3. Humidity: The relative humidity of the warehouse should be less than 70%, avoid too wet or too dry, and no condensation.
4. Temperature: 5-25℃ is the ideal storage temperature. Avoid exposure to heat and sunlight. Seals taken out from low temperature storage should be placed in an environment of 20°C before use.
5. Contact with liquid or semi-solid materials: Do not contact with solvents, oils, greases or other semi-solid materials.
6. Oxygen and ozone: The rubber material should avoid exposure to circulating air. This can be accomplished by packaging, wrapping, storing in an air-tight container, or other suitable methods. Ozone is harmful to most elastomers. Avoid the following equipment in the warehouse: mercury vapor lamps, high-voltage electrical equipment, motors and other equipment.
7. Deformation: The rubber parts should be placed in a free state as much as possible to avoid tension, compression or other deformation.
8. Lighting: Avoid sunlight and strong artificial light sources containing ultraviolet rays. UV-resistant bags provide optimum protection. Red or orange paint or film is recommended for warehouse windows.
9. Contact with metal or non-metallic materials: It is not allowed to contact with magnetic materials, cast iron, copper and its alloys, or materials containing materials that will damage rubber. Seals should not be packaged with PVC materia
