Ka for the fine silica in the air temperature 25 ℃, relative humidity of 60% of the moisture absorption rate of 30%; Kb for other desiccant (such as molecular sieve, alumina, activated clay, etc.) at the same temperature and humidity conditions, the moisture absorption rate.
Blue Indicating Silica Gel s SORB ® blue silica gel is ideal as a primary desiccant or blended with other desiccants in any application where visual control of moisture is required. sSORB silica gel beads are saturated with a moisture indicating solution that gives them a deep blue color when dry.
The Munters desiccant wheel stands out as the most energy efficient technique for creating humidity controlled environments. Our purge technology reduces regeneration energy by up to 30% and by means of cooler supply air the need of post cooling can be reduced by up to 70%.
Silica gel is an amorphous and porous form of silicon dioxide, consisting of an irregular tridimensional framework of alternating silicon and oxygen atoms with nanometer-scale voids and pores. The voids may contain water or some other liquids, or may be filled by gas or vacuum. In the latter case, the material is properly called Silica xerogel. Silica xerogel with an average pore size of 2.4 nanometers has a …
Bentonite is usually used in bags classified above 1 unit, whereas Silica Gel is used in very small desiccant bags. In other words, Silica Gel is often used by the medical industry. Although there is no difference in their ability to absorb moisture, Silica Gel is rather more expensive because of the chemical manufacturing process.
Silica gel packs, used in the packaging process of many products to keep out moisture, come with warning labels. Some of the products that use the packets include leather shoes, food, electronics and medications. By keeping out moisture, this desiccant helps prevent mold, mildew and corrosion.
This does not apply to molecular sieve desiccant. Please note that a unit of desiccant refers to its drying capacity, not its volume. A unit (approximately one ounce) is the amount of desiccant that will absorb at least three grams of water vapor at 20% relative humidity and at least six grams of water vapor at 40% relative humidity at 77 degrees F (25 degrees C).
Silica Gel . Silica gel is silicon dioxide (SiO2). It is a naturally occurring mineral that is purified and processed into either granular or beaded form. As a desiccant, it has an average pore size of 24 angstroms and has a strong affinity for moisture molecules. The silica gel will pull in moisture at temperatures up to 220°F (105°C).
