The Necessity of Using Silicagel Desiccant

Silicagel desiccant keeps goods best protected from moisture such as: wood industry, garments, leather shoes, electronics, rattan, bamboo, backpacks, handbags, medical equipment, food…etc.

Silicagel desiccant  is widely used in the current moisture-proof bag manufacturing industry in  Ho Chi Minh City, Hanoi, Dong Nai, Binh Duong, Bac Ninh, Thai Binh, Nam Dinh, Hai Phong…

The product is considered an effective moisture-proof solution for goods that need to be preserved for a long time. So do you know what desiccant silica is?

How many product lines are there today and where should you buy to get the best price for yourself?

This is also the useful information that Vu Anh Khoi Company wants to bring to you right away!

What is Silica Gel Desiccant?

Silicagel desiccant  is a desiccant made from the active ingredient Silicagel. In the chemical composition table, Silicagel is called Silicon Dioxide.

These desiccant beads are usually small in size, about 2-4mm. They have a full spherical shape and are filled with capillaries when viewed under a microscope. Currently, desiccant Silicagel beads are packaged in packages weighing from 1g to 500g depending on the type.

The product is carefully packaged and is not harmful to the user’s health, so it is widely used in many production lines.

Uses of Silica Gel Desiccant

Silicagel desiccant is used to absorb all moisture in the air to minimize the oxidation process on items that need to be preserved .

More specifically, when placed in the air, Silicagen desiccant will begin to absorb all the water vapor in the outside environment. Water vapor will be retained inside thousands of pores in the Silicagen desiccant.

Once saturated with water, the silica gel beads will begin to absorb water and become inactive. Typically, each silica gel bead can absorb about 40% of its weight in water vapor.

But you need to know that the product’s ability to absorb moisture also depends on the humidity of the outside environment in a balanced ratio.

To put it simply, if the humidity in the environment falls to about 20%, the desiccant will absorb about 12% of the water vapor.

If the humidity in the air reaches a relative level of about 90%, the desiccant will absorb excess moisture up to 31%.

Thanks to that,  Silicagel desiccant packets  minimize moisture penetration into food, electronics and other products that need to be preserved.

Accordingly, the oxidation process that corrodes components or the growth of microorganisms that damage food is also limited to the lowest level.

Goods are thus preserved for a longer period of time. The product’s lifespan is thus increased several times over normal.

Common Types of Silica Gel Desiccants

On the market today, there are many Silicagel Desiccants produced in different specifications to serve users. Among them, the most prominent are the following 3 types of desiccants:

1. White Silica Gel Desiccant Packet

Soft, spongy white silica gel desiccant  tends to change color from clear white to opaque white when fully hydrated.

The product is commonly used to preserve food, clothing, shoes, pharmaceuticals, cosmetics, agricultural products, containers and many other consumer goods.

On average, each pack of this type of desiccant can be used for 2 consecutive months. Thanks to that, you will save a lot of money on dehumidifying goods that need to be preserved before shipping.

2. Blue Silica Gel Desiccant

Blue Silicagel Desiccant has a characteristic blue color and a fairly solid structure. When you touch the desiccant with your hand, you will feel it is quite soft due to its high porosity.

That is why  blue Silicagel desiccant  has the ability to absorb water vapor extremely strongly and begins to change color when fully hydrated. Specifically as follows:

• Hydrated seeds :  From green to light pink or dark pink depending on the amount of moisture absorbed.
• Saturated seeds:  From dark pink to black pink.

Just by observing the color of the desiccant, you can completely know whether the product is full of water or not to replace the new bag of beads.

This type of bag is often used to preserve electronic components, transformers, electrical cabinets or other types of cameras that need to be moisture-proof.

3. Orange Silica Gel Desiccant

Compared to blue silica desiccant, orange silica gel bags are considered safer. Because they do not contain heavy metals, they are not harmful to the user’s health. The product does not corrode components and is also very friendly to the surrounding environment.

Blue Silica desiccant beads and orange Silicagel bags are considered safer and can be used for food products.

In fact,  orange silica gel desiccant  tends to turn green when it reaches a saturated state.

The product has a fairly low loss rate and high mechanical strength, so it is widely used to preserve many different products.

Such as food, pharmaceuticals, cosmetics, machinery components and containers.
