Or some special environment is the material, the production or storage environment cannot too big, the air humidity is too big later cause metamorphism, affect the quality of the object and use value. As a result, these places will need to use the dehumidifier. Let's talk about this topic in detail.
The first to have special request for air humidity material is optical lens. Modern optical lens, the surface has a layer of membrane. These membranes are some of the high polymer material. And these high polymer material is very suitable for the growth of mold. Here are a lot of nutrients for mould to absorb, so will breed quickly. Thus lead to the optical lens imaging sexual transmission of light and will become poor, and finally led to the mold the lens cover, lens didn't use value. Therefore, in the preservation of optical lens, should use the dehumidifier make indoor humidity is around forty percent.
The second is the magnetic recording materials. This is all made of polymer with a base. It contains a large amount of mold like plasticizer and dispersant, etc. To prevent gone mouldy magnetic recording materials, although at the time of production is also appropriate to join the fungicide, but the effect is not good. Even some marked is mouldproof disk, can prevent the growth of mold, just growth rate more slowly. Therefore, in the disk storage room, the use of dehumidifier keep the humidity of the air in forty percent disk can prevent mildew.
The third is the film. As we know, in the film, there will be a lot of photographic materials, which is a hotbed of mold growth. As a result, the film after be affected with damp be affected with damp, especially easy to hydrolysis reaction. And mold growth metabolism matter more for the film to destroy again. In the storage of film, the role of the dehumidifier can't underestimate. As long as the good control the humidity of the air, and then keep the environment health, film storage problem solved
