If the silicone stationery pencil case is not properly stored when not in use for a long time, it is easy to be affected by environmental factors and age. The following are some effective anti-aging methods.
1. Control of environmental conditions
The aging of silicone is closely related to the temperature, humidity, light and oxygen in the environment. First of all, temperature is one of the key factors. The silicone stationery pencil case should be stored in an environment with a relatively stable and moderate temperature, and the ideal temperature range is 15-25℃. Avoid high temperature environment, because high temperature will accelerate the movement of silicone molecular chains, soften and deform silicone, and even cause chemical bonds to break, causing aging. At the same time, it is also necessary to prevent too low temperature, which may make silicone hard and brittle, reducing its flexibility and elasticity.
Humidity also needs to be reasonably controlled. It is advisable to keep the relative humidity at 40%-60%. A high humidity environment may cause silicone to absorb too much moisture, resulting in water stains and mildew on its surface, which in turn affects its appearance and performance. An overly dry environment may cause silicone to dry and harden due to water loss. The storage environment should avoid direct sunlight, because ultraviolet rays can destroy the molecular structure of silicone and cause photoaging. The pencil case can be placed in a cabinet or covered with a light-shielding material. In addition, it is also important to reduce contact with oxygen, which will react with silicone to oxidize and accelerate the aging process. The pencil case can be packaged in a sealed bag and the air in the bag can be removed as much as possible.
2. Cleaning and maintenance
Before long-term storage, make sure the Silicone stationery pencil case is clean. Use a mild detergent and a soft cloth to wipe the surface of the pencil case to remove dirt, dust and possible residual chemicals. These impurities may react chemically with the silicone during long-term storage and accelerate aging. After cleaning, let the pencil case dry naturally and avoid using heating equipment such as a hair dryer to avoid local overheating and causing changes in the performance of the silicone.
3. Reasonable placement and support
When storing, the Silicone stationery pencil case should be avoided from being squeezed by heavy objects. If the pencil case is squeezed for a long time, its shape may change and the molecular structure inside the silicone may also be damaged. The pencil case can be placed on a flat shelf. For pencil cases with special shapes or structures, some soft supports (such as sponges, foams, etc.) can be used to maintain their shape and prevent deformation and aging.
