Silica Gel For Transformer

1,In Transformer,Which silica gel we will use?Blue silica gel!

The blue silica gel is translucent glass shape, usually divided into blue glue, blue discoloration glue and blue glue indicator. As desiccant indicator, general it is blue before moisture absorption, gradually becomes shallow blue after absorb the moisture, continue become pink during the process of absorb moisture that showing the need to change new silica gel or regeneration.

2,What is blue silica gel and why we use it in transformer?

Blue silica gel can use in moisture absorption separately. It usually used together with thin holes spherical silica gel desiccant because of it has the characteristics of discoloration which indicates the degree of desiccant moisture absorption and determine the relative humidity.

(1) High security: virulent insipidity, harmless to human body.

(2) Adsorption ability: 38%.

(3) High absorption and good packaging materials.

(4) Good thermal stability.

(5) Stable chemical properties and strong mechanical strength.

3,Except transformer,where can we use blue silica gel?

1). Mainly used in moisture-proof and rust-proof of instrument and meter and equipment in the airtight conditions.

2). Prevent corrosion and rusty of mold.

3). Widely used in shoes, hats, furniture, toys, hardware, gifts, wood products, etc.
