Respiratory protection equipment

1. Gas masks

1.1 Military use:

1. On the battlefield, activated carbon is a key component of gas mask canisters. For nerve agents (such as sarin, VX, etc.), activated carbon can adsorb the agent molecules in its pore structure through a combination of physical adsorption and chemical adsorption, and react with surface functional groups to prevent the agent from entering the respiratory tract and causing harm to soldiers.

2. In the face of corrosive agents (such as mustard gas, etc.), activated carbon can effectively adsorb these agents to ensure the safety of users in chemical warfare environments.

1.2 Civilian fields:

1. In chemical production environments, the activated carbon in the gas masks used by workers can adsorb toxic gases such as chlorine, ammonia, and hydrogen sulfide. For example, in the chlor-alkali industry, there may be a risk of chlorine leakage in the production workshop. The activated carbon in the gas mask can adsorb chlorine in time to prevent workers from being poisoned after inhalation.

2. In sewage treatment plants, since toxic gases such as hydrogen sulfide may be produced, the activated carbon in the gas masks worn by workers can adsorb hydrogen sulfide for protection.

2. Protective masks

2.1 Industrial protection:

1. In the mining industry, especially coal mining, the activated carbon in the protective masks can adsorb harmful substances such as carbon monoxide and dust. Among them, for carbon monoxide, a colorless and odorless but highly toxic gas, activated carbon uses its adsorption properties to reduce its concentration in the breathing air.

2. In metal smelting plants, various metal fumes and toxic gases are produced. The activated carbon in the protective masks helps to adsorb heavy metal pollutants such as lead smoke and mercury vapor and other toxic gases to protect the health of workers' respiratory systems.

2.2 Civil protection:

1. In daily anti-smog masks, activated carbon can adsorb fine particulate matter (PM2.5), odor substances (such as automobile exhaust odor, garbage incineration odor, etc.) and volatile organic compounds (VOCs) in the air, improve air quality, and protect the wearer's respiratory tract.

2. During the pollen season, activated carbon composite protective masks can absorb pollen particles while removing odors caused by microorganisms that breed pollen.
