Blue Silica Gel
Characteristics
Shape: glass-like pellets or lumps. Color: blue or light blue.
Including blue gel indicator, chromotropic silica gel and blue silica gel.
Turning from blue to red after absorbing moistures.
Use
Mainly used for absorbing moisture, anti-rusting of
|
 |
|
| |
|
instruments, gauges and equipment in the enclosed conditions. After absorbing moisture, it turns from blue to red, visually indicating the relative humidity of the given environments.
When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moisture and judges the relative humidity of a given environment. It is widely used as silica gel drier for the packing of precision instruments, leathers, shoes, clothes, foodstuffs, medicines and household electric appliances,etc.

Nontoxic, odorless
In comparison with ordinary blue gel, blue silica gel DL possesses the feature of quanti tative discoloring, i.e. when adsorbing a certain amount of moisture, it begins coloring and does not stop coloring until a specified amount of moisture is adsorbed.
|
|
|
It is widely used as humidity indicator and drier in judging if the adsorption &drying process is up to the requirements.
Use:
1. Used for absorbing moisture of instruments, gauges and equipment in the enclosed conditions.
2. After absorbing moisture, it turns blue into drier, visually indicating the relative humidity of the given environment.
3. When being used with ordinary silica gel or drier, it indicates to which extent the drier absorbs the moistures and judges the relative humidity of a given environment.
4. Used to judge if the humidity of an environment is up to the specified requirements and to determine if the adsorbent or ceases to be effective.

Chemically stable, flame-resisting. Insoluble in any solvent.
In comparison with fine-pored silica gel, the adsorption capacity of fine-pored silica alumina gel
is quite the same when used
at low
relative humidity, (e.g., RH=10%, RH=20%), while its adsorption capacity at high humidity is 6-10% higher than that of fine-ported
|
|
| silica gel. Its thermal stability is over 150æ higher than that of fine-pored silica gel (200æ). Ideally suited for use as adsorbent and Variable-temperature adsorbent. |
Use
Mainly used forthe dewatering of natural gas, adsorption and separation of light hydrocarbon at variable temperatures. It may also be used as catalyst and catalyst carrier in petrochemical industry, industrial drier, liquid adsorbent and gas separator, etc.

Silica Gel Cat Sand
FEATURES OF SILICA GEL CAT SANDS
1.Great Capacity and Quick Speed of Absorption
Silica gel cat sands can absorb all excrement and urine of pets and peculiar smell given off from them. They can also control the growth of bacterium and keep the surface of the sands dry and cleen,so the pets may live in a safe and sanitary environment. At the same time, silica gel cat sands can be used as an air-fresh agent, which absorbs some easy-volatile gas and moisture in the air and make the room fresh and clean for us all. Because silica gel cat sands have their unique performance, that is only small amount of waste was produced, the pets'owners will become happy and relaxed.
2.Small Amount and Long Term of Usage A bag(3.6L) of cat sands can be used for one cat, one month. |

USE METHOD
1. Spread out a Iayer of cat sands with thickness 1.5 inch in a cat sand box.
2. Clean the waste regularly to keep the box clean.
3. If you have several cats, you may shorten the replace period and mustn't put too many cat sands. A bag (3.6L) for one cat one month; two cats, 15days; three cats, about 10 days.
4. Cat sands saturated by the pet feces must be moved with the spoon.
5. The method for prolonging the use period:
1) As using them, we should put the box in a ventilating and dry place.
2) After use, put them in a dry place.

Silica Gel Color-variable SG
In the form of spherical or irregularly-shaped grains, the gel is currently presented either purple, orange or yellow. With silicon dioxide as the chief ingredient, the product performs all the functions of blue silica gel but does not contain cobalt chloride and is therefore innocuous and pollution-free, and its color varies as humidity changes
Use
Mainly for drying and indicating humidity of precision instruments, medicine, petrol chemicals, foodstuff,
clothing, leather, electric appliances, other industrial gases, etc. |
|
|
|
|
How to use
Put proper amounts in a suitable container or package and set the container or package where drying or humidity indication is needed. This gel can be used independently or in combination with other types of silica gel. After changing color as a result of absorbing dampness, the gel can be reused after heating to change back to its pre-use color. Heating is most suitable between 100-120
