O Ring Seals may be affected by external environmental factors such as distortion, oxygen, ozone, light, heat, moisture, oil, or chemical solvents. O Ring Seals may fail due to their physical and chemical properties The In the DIN7716, ISO2230, DIN9088 and other standards on the rubber seal storage, cleaning, maintenance made the basic provisions.
1: O Ring Seals Temperature: 5-25 ℃ is the ideal storage temperature. Avoid contact with heat and sunlight. The seal removed from the low temperature storage state should be placed in an environment at 20 ° C before use.
2: O Ring Seals humidity: the relative humidity of the warehouse should be less than 70%, to avoid too wet or too dry, can not appear condensation phenomenon.
3: O Ring Seals light: to avoid the sun and strong ultraviolet light with artificial light. Anti-UV bags provide the best protection. It is recommended that the windows of the warehouse be painted with red or orange paint or film.
4 O Ring Seals radiation: to avoid ionizing radiation damage to the seal.
5 Oxygen and Ozone: The rubber material should be avoided in the circulating air. This may be achieved by packaging, winding, storing in an airtight container or other suitable means. Ozone is harmful to most elastomers. Avoid the following equipment in the warehouse: Mercury vapor lamps, high voltage electrical equipment, motors and other equipment.
6 deformation: rubber parts should be placed in a free state as far as possible, to avoid being stretched, compressed or other deformation.
7 Contact with liquid or semi-solid material: Do not touch solvents, oils, grease or other semi-solid materials.
8 Contact with metal or nonmetallic materials: Do not allow contact with magnetic materials, cast iron, copper and its alloys, or materials that may damage the rubber. Do not use PVC material to pack the seal. Seals of different materials can not be mixed.
9 Cleaning: If necessary, you can use soap, water to clean the seal. But the water is not touchable fiber reinforced seals, rubber metal bonding seals, AU material seals. Disinfectants, organic solvents and sharp edges of the tool shall not be used. After cleaning the seal should be dry at room temperature, not close to heat.
O Ring Seals The retention period of the seal
O Ring Seals The retention period of the seal is determined by the material type and storage conditions of the rubber. In the recommended storage conditions, the material
O Ring Seals The shelf life of the seal is as follows:
1 polyurethane, thermoplastic material 4 years
2 nitrile rubber, hydrogenated nitrile rubber, chloroprene rubber for 6 years
3 Ethylene-propylene rubber for 8 years
4 fluorine rubber, silicone rubber, fluorine silicone rubber 10 years
5 perfluoro rubber for 20 years
6 polytetrafluoroethylene indefinite
O Ring Seals After the above period, after the use of rubber parts should check the characteristics, or can use for some time.
