Description

Introduce:

Silica gel desiccant is moisture -permeable pouch packed with different varieties.

The mian raw material of silica gel is highly porous structure of aqueous silica.non toxic, Tasteless, and no smell.
Chemical properties are stable. It has a strong hygroscopic performance. It is a highly active adsorbent material. Usually with sodium silicate and sulfuric acid reaction. And through aging, acid bubble and a series of post-processing to obtain. Silica gel is belonging to amorphous material. Its shape is Irregular sphere.

Chemical formula is mSiO2·nH2O. So it is widely used in instruments, meter, Equipment machinery, leather, luggage, shoes textile, food, medicine and other storage and transportation Controls the relative humidity of the environment.
To prevent the goods damp, Mildew and rust.

Medicine, machinery, optical electronics, precision instruments, instruments, seeds, processed foods, tea, all kinds of chemical fiber textile, leather shoes, leather, sports shoes and cultural relics archives, cameras, arts and crafts and all need Moisture-proof and mildew items, Its scope of application is very wide, The Specific description are as follows:

Can be used for bottled drugs, food moisture. To ensure that the contents of the items dry, to prevent the growth of various molds.
Can be used as a general packaging desiccant. Such as luggage, clothing, shoes and hats, leather, etc., to prevent the goods in the storage or transportation process due to moisture and affect product quality.
Can be easily placed in electronic products, instruments, household appliances, machinery and equipment and other products, to prevent the goods due to moisture and affect product quality.
Can be placed in the transport container, to prevent the container due to rain and wet.
The most suitable moisture absorption environment is room temperature (20 ~ 32 ºC), high temperature (60 ~ 90 ºC), it can reduce the relative humidity of the environment to about 40%, so the use of desiccant is very wide.
