Storage method of high pressure seal
High pressure seal and support is often used for storage of spare parts for a long period of time. Most of the rubber material physical properties in the process of storage will change, eventually can no longer be used. For example: excellent, too soft, cracks and or other forms of surface aging. These changes are the result of a combination of special factors or factors, such as deformation, oxygen, ozone, light, heat, humidity, or oil and solvent. If some simple measures are taken, the storage time of these products can be extended greatly. The key points for the storage, cleaning and maintenance of the elastomer seal elements are formulated in the international standard.
Recommended value for the storage life of different materials in the standard. In order to maintain the best physical and chemical properties of the components, the following rules shall be observed:
Heat
Ideal storage temperature is in the +5 C to +25 C, should avoid direct contact with the heat source, such as boiler, heat sink, avoid direct sunlight. If the temperature is less than +5 C, the seal may be stiff, and should be carefully removed, and the temperature of the seal should be picked up to about 25 C.
Humidity
The relative humidity of the storage room should be less than 70%. Should avoid too wet or too dry.
Light
Like plastic seal should be stored in the light of the sun, in particular, in the light of the sun or in the presence of ultraviolet light. Part of the application of anti UV packaging independent packaging.
A red or orange curtain is recommended to cover the window of the storage room.
Radiation
In the case of electronic radiation, the Department should take special precautions to avoid damage to components.
Oxygen and ozone
If possible, the elastomer should be packed and stored in a sealed container, which is not affected by air. Because ozone can damage the elastomer and storage premises of a elastic body should not be placed may produce ozone equipment, such as UV lamp, high voltage equipment, motor, electric spark or static discharge. Combustion gases and organic vapors can also produce ozone in the light of the photochemical reaction, so the storage room can't have these gases.
