Activated Carbon For Gas Mask-Heycarbons Manufacturer From China
Activated carbon has strong adsorption capacity and can absorb a variety of toxic substances. Activated carbon can be used in gas masks A, B, E, K to protect human health.
What is an Activated Carbon Mask?
Using activated carbon technology in masks can enhance the protective effect.
Physical adsorption
Activated carbon is carbonized and activated to form a developed pore structure that can efficiently adsorb gas molecules.
When the toxic gas in the air passes through the activated carbon layer, the gas molecules are attracted by the surface adsorption force in the micropores and adhere to the surface of the activated carbon, and no longer enter the respiratory system.
Chemical adsorption
By impregnating activated carbon with specific chemical reagents (such as acids, alkalis, metal oxides, etc.), it is allowed to neutralize, redox or complex with certain toxic gases. Activated carbon can convert toxic gas molecules into non-toxic or low-toxic substances, improving the filtering effect.
Activated Carbon For Fas Mask Treatment Process
Toxic gas enters the mask filter layer
When a person breathes while wearing an activated carbon mask, outside air (which may contain toxic or harmful gases such as formaldehyde, benzene, ammonia, sulfur dioxide, etc.) is inhaled.
Activated carbon absorbs toxic gases
Toxic gases pass through the activated carbon layer, which is built into the mask to effectively capture and adsorb molecules in the air.
- Activated carbon mainly adsorbs toxic molecules on its surface through physical adsorption (van der Waals forces).
- For some gases, chemical adsorption can also be performed, that is, the surface of the activated carbon may be pre-treated with some chemical agents (such as acids, alkalis, metal oxides) to react with toxic gases and convert them into harmless substances.
Clean air enters the respiratory tract
After the toxic gas is adsorbed, the treated clean air continues to flow into the mouth and nose and is inhaled by the human body.
Lifetime Limitation
Activated carbon has the characteristic of adsorption saturation. Once the pores are filled with toxic gases, the filtering effect of the mask will be significantly reduced.
Therefore, the activated carbon mask needs to replace the filter element regularly, otherwise it may cause reverse adsorption (the adsorbed harmful substances will be released again).
Activated Carbon For Gas Mask Protection Type
According to different types of poisons, the protection types can be divided into the following types: A B E K, etc. (according to GB2890-2009). The detailed information is listed in the table below.
| Filter Type | Color | Toxic gas types protected |
|---|---|---|
| A | brown | Organic gas |
| B | grey | NH3, H2S |
| E | yellow | Acid Gas |
| K | green | NH3, H2S |
| H2S | blue | / |
| Hg | red | Mercury vapor |
| CO | white | CO |
| ABEK | grey | Comprehensive protection |
| According to GB2890-2009 | ||
Is activated carbon safe to breathe?
Activated carbon is encapsulated in the filter element of the gas mask and is safe for the human body.
Activated carbon captures harmful gases and particles in the air through physical and chemical adsorption, and does not release toxic substances or actively harm the human respiratory system.
In gas masks, activated carbon is usually encapsulated in the filter element and is not directly inhaled. Therefore, the user will not inhale activated carbon dust and will not cause physical damage to the lungs.
Activated carbon mask benefits
1. Super strong adsorption capacity
Activated carbon has a high specific surface area (the surface area per gram of activated carbon can reach 500-1500 square meters), which can effectively adsorb a large number of toxic molecules.
Its porous structure can capture tiny molecules, including: Organic solvents (benzene, formaldehyde, gasoline vapor), acidic/alkaline gases (such as chlorine, ammonia), etc.
2. Strong customizability (chemical modification)
Activated carbon can enhance its adsorption capacity for specific poisons through chemical impregnation or surface treatment:
- It can adsorb acidic gases after adding alkaline substances;
- It can treat alkaline gases or reducing poisons after adding acid or oxidant.
3. Rapid response, high efficiency
The contact time of gas passing through the mask filter is short, but activated carbon can complete adsorption in a very short time to ensure the user’s breathing safety.
Best Activated Carbon Gas Mask Product Type
Depending on the type of poison, different types of activated carbon are required for gas filtration. Heycarbons has a wide variety of products for you to choose from.
There are protective carbon products such as HEY A, HEY AE, HEY K, HEY ABEK, etc.
In fact, in addition to coconut shell activated carbon, we also recommend using coal-based pelletized activated carbon with an iodine value of no less than 1000 mg/g, and the diameter is mostly 0.9 mm. After the customer purchases the base carbon, they can do the impregnation processing themselves.
