All kinds of Desiccants difference
Silica gel desiccant, clay desiccant, molecular sieve and calcium chloride desiccant.
The feature of all kinds of desiccants and their application:
The most common desiccants are silica gel desiccant, clay desiccant, calcium chloride desiccant, molecular sieve desiccant and others.
SILICA GEL DESICCANT
Silica gel desiccant is the most traditional and widely used desiccant.
Features of silica gel desiccant
1. Non-toxic, tasteless, chemical stability, good thermal stability,
2. Strong adsorption capacity under various conditions.
3. Wide range of applications.
Indicating silica desiccant
Indicates silica gel include blue silica gel and orange silica gel. Indicating silica gel has the same performance with transparent silicone. the color changing after absorbed can indicating absorbent state.
MONTMORILLONITE CLAY DESICCANT
Montmorillonite desiccant also known as bentonite desiccant.the raw material of montmorillonite clay is irregular with purple yellow, gray colors.
It is non-toxic, natural and has strong adsorption ability. In usual, 1 unit desiccant equivalent to 33 gram montmorillonite clay. Meets the US military standard MIL-D-3464E, China military standard GJB2714-2005.
Features:
1. Fully degradable in nature, environmental, non-toxic and harmless
2. in a low humidity circumstance , the moisture absorption performance is higher than silica gel desiccant
3. It has a neutral PH value, very suitable for high-end electronic products
MOLECULAR SIEVE DESICCANT
Molecular sieve is a crystalline aluminum silicate compound, which has a regular structure and uniform proes.
It only allow the apertures that the diameter smaller than molecules entering. therefore called molecular sieves.
Features:
1. In the ultra-low-humidity conditions, it still able to absorb a large amount of water vapor in the environment, effectively control the humidity.
2. it will absorb a large amount of water vapor within a very short time.
CALCIUM CHLORIDE DESICCANT
Calcium chloride desiccant, is a new environmentally friendly desiccant. Its high absorption rate 300% (RH ≥ 90%), efficiently reducing the relative humidity in the sealed bag and ensure cargo safe storage and transportation, Protect cargo from moisture, mildew. More and more popular recent years.
Features:
1.Provides effective long-lasting protection from moisture.
2.Able to absorb a massive 250- 300% of its own weight in moisture (RH ≥ 90%).
3.Much more effective than silica gel or clay desiccants.
4.Will not leak or spill.
5.Easy to install.
6.Use small quantity, save cost.
