1. Optical lens In order to improve performance, modern optical lenses are coated with multiple layers of polymer materials on the surface of the lens. This layer of synthetic material provides rich nutrition for the growth and reproduction of mold. The mold decomposes the components of the film on the surface of the optical lens for growth and reproduction. , Until the mycelium covers the entire lens. To ensure the safety of the optical lens, the lens should be stored in an environment with a relative humidity of about 40%.

2. Magnetic recording materials Magnetic recording materials are all made of polymer materials with a base, and the plasticizers, dispersants, etc. contained in them are suitable for mold decomposition and absorption, although each magnetic recording material company is more or less in the production. An anti-mold agent is added, but the so-called "anti-mold disk" does not guarantee that the disk will not grow mold at all, it is just the difference between the probability and the speed. In fact, as long as the relative humidity of the environment is controlled at 40%, the purpose of safe storage can be achieved.

3. The film information carrier of the image film is composed of a polymer material base and an organic photosensitive material coated on the surface, which is suitable for mold decomposition. In particular, the photosensitive film on the surface is most susceptible to mold attack. The photographic film latex layer photosensitive film is also very susceptible to moisture and hydrolysis, which can damage the film image. After the growth of mold, the oxalic acid excreted by the mold can erode the silver shadow particles and the dye image. The ideal long-term storage environment for photographic film is a relative humidity of 40%, a temperature of 1-8 degrees Celsius, and environmental air purification, which can achieve the purpose of safe storage.

4. Optical recording Electronic information media Optical recording is to record signals by recording small pits on the surface of the disc, and then plate a layer of aluminum film to reflect the signal. However, the plastic protective film on the surface of the disc has the property of penetrating a small amount of water. , In a high-humidity environment, the brightness of the aluminum film will be oxidized due to the electrochemical effects of moisture, resulting in a decrease in brightness, causing the disc to be unable to read or read the wrong signal, causing it to be used for normal playback and discarded. Therefore, to prevent oxidation, store the disc in an environment with a relative humidity of 40% to ensure safety.

5. Electronic devices. Most electronic products are required to be stored under dry conditions. Otherwise, the capacity of the capacitor will be reduced when it is damp, and integrated circuits, etc., will easily cause internal failures when it is damp; moisture will also oxidize the pins and connectors of the computer CPU and board card gold fingers and electronic equipment, resulting in poor contact or poor solder joints. , Oxidation of crystals, etc. Store electronic devices in an environment with a relative humidity of 50% to ensure safety.

6. There are many varieties of precision machinery, instruments and high-brightness metal precision machinery, such as spectrometers, high-precision balance precision instruments, block gauges and other precision measuring tools, as well as other precision measurement, measurement, processing, experiment and other precision machinery products and high-brightness metals Objects, even if they are oxidized by trace amounts of moisture, will be inaccurate, reduced in accuracy, reduced in brightness, resulting in reduced performance and even scrapped. Modern precision instruments often have electronic components, which can cause malfunctions when exposed to moisture. Store it in a 50% relative humidity environment to ensure safety.

7, powder material copier toner, powdered medicine, powder metallurgy materials, powdered chemical materials, and powdered materials such as milk powder, coffee, etc. will deliquescence, agglomeration, or changes in properties and chemical components when they are damp, resulting in loss of efficacy and thus affecting use Or scrap. Store it in a 30-40% relative humidity environment to ensure safety.

8. Chemicals and medicines, spices. Many types of chemicals and medicines can cause changes in their ingredients and properties when they are damp. Some Western medicines, Chinese patent medicines, and Chinese medicinal materials will reduce their composition and efficacy or cause adverse changes when they are damp. Mold will cause scrap. Spices will lose the aroma, and the adhesive will solidify in an instant. Store it in a 50% relative humidity environment to ensure safety.

9. Paper, wood, silk, and leather products Paper products are widely used in archives, literature, cultural relics, calligraphy and painting, stamps, photos, and various important bills, filter paper, test paper, etc. Wood products, silk products, leather products, etc. are widely used in various aspects of life, art and antiques. They all contain a lot of cellulose, which can be decomposed into glycogen and absorbed by mold after being damp, so it is easy to cause mold attack. The chemical test paper also fails to indicate normally due to changes in its composition. Store it in a 40% relative humidity environment to ensure safety.

10. Tobacco, grain, tea, seed tobacco, grain, tea, seeds, etc. are very susceptible to moisture and cause damage: tobacco, grain, tea will become moldy and moldy seeds will not germinate. In particular, once a large number of the above-mentioned items stored in a large amount of storage are moldy and rotten, the loss caused is even more shocking. And storing it in a 50% relative humidity environment plus timely turning over can ensure safety.

The above is what Nsida introduced to you about the damage mechanism and protection of mold oxidation and corrosion in the humid production environment. Please feel free to contact us for more information about temperature and humidity control in production and manufacturing.
