Products overview:

Silica gel desiccant moisture permeability is small bag packaging of different varieties of silica gel, the main raw material high silica gel is a kind of micro pore structure of hydrated silica, non-toxic, tasteless, odorless, stable chemical properties, with a strong hygroscopicity. Is a highly active adsorption material, main composition is sio2, is a highly active adsorption material. Usually is to use sodium silicate and sulfuric acid reaction, and the aging, acid soak and a series of post-processing process and system. Silica gel is amorphous material, its shape transparent not gauge side sphere, its chemical formula is mSiO2. NH2O. Is the only FDA approved dryer can be directly contact with the food and drug. Is widely used in instruments, meters, instruments, leather, bags, footwear, textiles, food, medicine and other relative humidity of the storage and transportation of control environment, prevent items be affected with damp be affected with damp, mildew and rust. Including: transparent silicone maintain primary colors after moisture absorption, but placed for a long time in colored air environment, colored molecules in the air after adhesion, and can be dyed). Blue and orange silica gel, often can have the effect of display agent, blue silica gel after moisture absorption, to red, orange silica gel after moisture absorption, turn green.


Quality indicators

Quality indicators meet the HG/T2765-2005




Project reference standard

Water adsorption RH = 20% > 10% > 20% > 30%

RH = 40%

RH = 80%

RH = 95%

Water content < 5%

Note: according to standard GB10455-89: when RH = 90% qualified products 28% or higher grade a classy article 30% or 29% or higher


The security performance of the silica gel

Silica gel has a strong adsorption ability, drying effect on a person's skin, therefore, operation should be dressed in the uniform. If the silica gel into the eyes, need a lot of water flushing, and find a doctor as soon as possible.

Silica gel itself is a neutral material, in addition to react with strong alkali, strong acid under certain conditions, will not react with any other material.

Silica gel desiccant after eating, don't worry. It won't cause harm to human body, also won't be absorbed by human body. After eating can drink some milk, the silica gel desiccant will soon with human waste.


Medicine, machinery, optical electronics, precision instruments, meters, seeds, processed food, tea, all kinds of chemical fiber textile, leather shoes, leather, shoes, and cultural relic archives, cameras, arts and crafts, such as all items need to moistureproof mildew, application is very extensive. Specify the following

1, silica gel desiccant can be used for bottled medical, food, moistureproof. To ensure that the content items dry, to prevent the growth of a variety of miscellaneous mold.

2, silica gel desiccant can be used as a general packaging desiccant. Such as bags, clothing, shoes and hats, leather, etc., to prevent the goods due to be affected with damp be affected with damp during storage or transportation affect the quality of the product.

3, silica gel desiccant can be conveniently placed in the electronic products, instruments and meters, household appliances, mechanical equipment, and other products, to prevent the goods because of be affected with damp be affected with damp and affect the quality of the product.

4, silica gel desiccant can be placed in the transport of the container, and prevent the formation of container rain.

5, silica gel desiccant is most suited to the moisture absorption of the environment for the room temperature (20 ~ 32 ℃), high temperature (60 ~ 90 ℃), it can reduce the environmental relative humidity around 40%, so the desiccant application scope is very broad.


Core strengths

1, the effective moisture absorb more than 30% of its weight

2, don't change their shape after moisture absorption, non-toxic, harmless, free from contamination

3, good thermal stability and strong mechanical strength

4, wide range of USES, shoes and hats, leather, handbags, food, medicine, hardware, toys, wood products, instruments and meters, electronic appliances, etc all can use




Non-woven material features:

Non-woven fabric with a unique layer product extension method, the PET fiber and PP/PE fiber one-time close together, form the outer surface of PET, the inner surface of PP/PE unique multilayer structure. High tensile strength and tear strength, permeability is good at the same time. Is one of the few can back to bake with desiccant packaging (110 ℃).


Simple product whether failure self-checking method:

1, will tear apart the desiccant bag, silicone raw materials hold hands, look to whether have a fever, heat dissipation, silica gel is effective.

2, if you have to add blue glue, plastic orange indicator, indicator has become angry, silica gel has failed.

3, small cup of cold water, tear desiccant bag, the raw materials into the water, whether silica particles will be blown to pieces, and issued a "scrape" sound, is that is effective.

4, take a small bag of desiccant, said good weight, marking, placed indoor, every 5 to 10 days and then weighing, to see whether there will be increasing weight, there have been increased effectively.

5, if you need to know accurate moisture absorption performance of the desiccant, need testing laboratory equipment.
