High efficient drying desiccant for electronics equipment instrument
Electronic instrument internal power transformers and other wound components (such as winding resistor, potentiometer, inductance coil, moving coil meter, etc.) with the dielectric strength, often falling down due to be affected from damp, breakdown, leakage, mildew and break even, make the equipment failure. Therefore, the electronic instrument need to keep effective damp-proof and moisture displacement measures must be taken.
First of all, the electronic instrument storage, the choice of relatively dry packaging, storage location of good ventilation. Inside the packaging of precision instruments, silicone or montmorillonite desiccant should be placed to absorb moisture. Should regularly check whether the desiccant is dry < silica gel desiccant should be white translucent granular if it is found that the silica gel agglomeration becomes yellow, indicating that its water absorption function has declined, should be replaced with a new silica gel desiccant. Montmorillonite desiccant if agglomeration, moisture should also be replaced). In the wooden case of the instrument, also should attach desiccant bag.
Mobile phone is extremely vulnerable to the humid environment. First of all, the electronic components inside, moisture will slowly corrode the mobile phone motherboard, resulting in the mobile phone is not switched on scrap. Secondly, the touch screen in a humid environment as easy as water bad screen, the screen will be distorted by moist air. For the display screen, humidity will affect the normal work of the circuit board, damage the function of the display screen and service life. Put the desiccant in the package is to use physical moisture absorption method, reduce the moisture in the air, so as not to worry about the screen will be affected by moisture.
Specification of desiccants:
Silica gel desiccant is a kind of colorless or transparent or translucent silica beads (also known as silica), which is a kind of crystals can't afford to chemical reaction, there are interior pores of the crystal is very fine mesh structure, the wool stoma that can absorb moisture, and through its physical attraction and retain moisture. Even if the desiccant is completely immersed in water, it will not soften or liquefy. It is non - toxic, tasteless, non - corrosive, non - polluting characteristics, so it can be in direct contact with any items.
Montmorillonite Clay desiccant is a naturally occurring porous drying adsorbent. The mined clay is activated for use as a desiccant through careful drying. This clay will successfully regenerate for repeated use at very low temperatures without substantial deterioration or swelling. However, this property causes clay to give up moisture readily back into the container as temperatures rise. Clay is inexpensive and effective within normal temperature and relative humidity ranges (Table 1). Some variation in performance can be seen due to its source as a naturally occurring material.
Silica gel desiccant moisture absorption
Montmorillonite desiccant moisture absorption
25℃, RH=20%, ≥11%
25℃, RH=40%, ≥18%
25℃, RH=90%, ≥30%
1. Put the silica gel desiccant / Montmorillonite Clay desiccant into the packaging bag (box) together with the product, and then seal it would help the desiccant better protect the product.
2. The usage amount can be determined to the different product, packaging space, storage conditions (such as temperature and humidity) and the density of packaging materials. It is recommended that each cubic meter of packaging space should be no less than 1500 grams of silica gel desiccant / montmorillonite desiccant.
3, silica gel desiccant / montmorillonite desiccant is non-toxic, but not edible.
