Q: What issues should be paid attention to when storing rubber hose products?
Answer: As the hose may be exposed to various environments during use, the physical properties will change accordingly. Therefore, in order to maintain the most suitable state of use during use, the following points should be paid attention to during storage to prevent the properties of the hose from changing in the storage environment.
1. Storage time
When storing, the storage time should be shortened as much as possible, and the "first in, first out" cycle method can be adopted. If it is necessary to extend the storage time, such as one year, the hose should be fully inspected before use.
2. Temperature and humidity
Storage temperature should be maintained at 0°C/32°F to 35°C/95°F (optimum 15°C/59°F). The relative humidity should not exceed 65%.
The hose should be stored in a dark place away from sunlight and strong artificial light. Windows in storage places should be painted red, orange or white.
Ozone will destroy rubber materials, and there should be no ozone-releasing substances in the storage environment, such as mercury lamps, mercury tubes, high-voltage electrical equipment, motors, and other substances that may generate sparks and static electricity.
5. Storage environment
All fittings including hoses shall not be exposed or contacted with solvents, fuels, oils, greases, volatiles, acids, disinfectants, etc. In addition, metal materials such as copper, iron and manganese can also damage rubber.
6. Heat source
The storage location should be kept at a sufficient distance from heat sources (including heating equipment) to meet the temperature specifications in Article 2.3. If a sufficient distance cannot be maintained, heat shields should be installed.
7. Electric field and magnetic field
There must be no electromagnetic field changes in the storage place. Changes in electric or magnetic fields will cause currents to be generated in the metal coil of the hose wind, causing the hose to heat up. Such strong electric and magnetic fields can be generated such as high-voltage cables and high-frequency generators.
8. Storage conditions
The hose should not be artificially compressed, elongated or excessively deformed during storage. Do not come into contact with any sharp metal. Store in a dry environment, if conditions permit, store in a separate area. The crown of the hose should be laid flat when it is rolled up for storage. If it needs to be stacked, the stacking height should not exceed 2 meters, and the lower hose should be prevented from being permanently deformed by pressure. Heavier products should be placed below, and lighter ones can be placed above. The bend radius of the coil shall not exceed the minimum bend radius of the product standard. Straight tubes should lie flat and not foldable.
