Fungus is the biggest enemy for digital cameras. This is because the lens surface of the camera is coated with a film, which provides rich nutrients for fungal growth and reproduction. Fungus decomposes the film on the surface of the lens and spreads like branches on the surface of the lens, which deteriorates the light transmission and imaging quality of the lens. The consumer-grade digital cameras we have in our hands cannot replace the lens, unless a waterproof digital camera is chosen, otherwise they are easily damaged. Metal body and metal components in circuits will undergo electrochemical reactions when they come into contact with moisture and oxygen in the air for a long time, causing the metal to rust due to oxidation and corrosion. Therefore, it is necessary to do moisture-proof work for the camera in this season. The emergence of a camera dehumidifier cabinet has to some extent solved this problem.
The electronic moisture-proof cabinet uses shape memory alloy dehumidification technology, which does not leak water and does not condensate, and can effectively prevent the camera lens from getting damp and moldy. Moisture-proofing is a seemingly simple but very necessary topic, especially for coastal cities. Coastal cities have the most suitable humidity and temperature environment for fungal growth, especially in rainy seasons with long rainy periods and high temperatures, which makes camera lenses particularly prone to moisture. Therefore, moisture-proof work in southern coastal cities should be done in advance. Normally, try to turn on the camera as much as possible, press the shutter button, and keep the camera lens in working condition. If not in use, try to put the camera lens in the electronic moisture-proof cabinet, and try not to put it in a so-called sealed but very humid bookcase or wardrobe.
Things at home that are prone to moisture can be placed in it, such as calligraphy and paintings, tea, etc.
The humidity requirements for items stored in the electronic moisture-proof cabinet are as follows:
55%-60% Antiques, paper money, fax paper
45%-55% Cameras, lenses, filters, computer accessories, slides, tapes, CD ROM, PDA, microphones
40% or less Optoelectronic semiconductor components, electronic parts and other products and semifinished products with possible metal surface oxidation
40%-50% Precision metal products, silverware, copperware, model cars, tools, measuring tools, instruments, etc. with possible metal surface oxidation
40% or less Medicines, health foods, Chinese and Western medicinal materials, dried foods, easily damp and caking food materials
30% or less Chemical raw materials: pharmaceutical raw materials, seasonings, paints, powders, powder materials, adhesives;
20% or less Farm research supplies: seeds, pollen, dried flowers.
Display and control
Nowadays, dehumidifiers on the market are divided into two types, one is digital and the other is pointer.
So how should we choose between these two dehumidifiers?
Pointer-type dehumidifiers are like a dial the size of a wristwatch. The error is relatively large and the humidity control is not good. It is also inconvenient to observe.
Therefore, I suggest choosing a digital dehumidifier when purchasing, which looks more clear and simple.
Because the moisture-proof cabinet is a relatively dry environment, it needs to have good anti-static design.
Here, I suggest choosing a dehumidifier dry cabinet with anti-static protection as much as possible when selecting.
Since it is a moisture-proof cabinet, it is necessary to focus on its dehumidification speed. If the dehumidification speed is too slow, there will be little difference between the devices placed inside and those placed outside.
Therefore, when selecting, try to choose a dehumidifier with a faster dehumidification speed, about 1-2 hours is recommended here.
