How Effective Is Activated Carbon In Absorbing Formaldehyde? Which Kind Of Activated Carbon Is Effective?

octobre 29, 2024

We all know that formaldehyde is very harmful to our human body, so we must adsorb formaldehyde before moving into a new house. There are many ways to absorb activated carbon, which is one of the methods of activated carbon adsorption, but activated carbon is actually divided into a variety of activated carbon absorption of formaldehyde useful? As well as the absorption of activated carbon that effect is better?

Activated Carbon In Addition To Formaldehyde Useful

1. Activated carbon is mainly used to adsorb formaldehyde and other harmful gases, filtering out insoluble, adsorption of some soluble. Activated carbon composition is mainly the use of charcoal, a variety of shells and coal as raw materials, through physical and chemical methods of raw materials for crushing, sieving, catalyst activation, rinsing, drying and screening and a series of processes and manufacturing. It has a strong physical adsorption and chemical adsorption effect, which can adsorb certain organic compounds to achieve the removal effect. 2.

2. Activated carbon can adsorb formaldehyde, ammonia, benzene, xylene, radon and other indoor harmful gas molecules in the air, for the living room, furniture closet, bookcases, shoe cabinets, shoes, refrigerators, bathrooms, floors, fish tanks, automobiles, air conditioning, computers, hotels and entertainment venues, have a very good effect, can be effective in adsorption of harmful gases such as formaldehyde, filtering out the insoluble, adsorption of some soluble. Therefore, together with gas catalyst and other chemical treatment methods, they are used as household formaldehyde removal and indoor air purification.

3. Role of Granular Activated Carbon (GAC)

Granular activated carbon (GAC), the smaller the particles, the better the adsorption effect, but the resistance is larger, also easy to leak carbon. Therefore, water purifier manufacturers generally choose moderate particles of carbon particles, generally between 10 to 24 mesh, small water purifiers choose 16 to 32 mesh. And granular activated carbon is more suitable for use in the refrigerator odor adsorption or car wash and other small-scale use.

Which Type Of Activated Carbon Is Effective In Removing Formaldehyde

Activated carbon can be divided into wood activated carbon, shell activated carbon, mineral raw material activated carbon, synthetic resin activated carbon, regeneration activated carbon and so on. We commonly use the following types of activated carbon.

1. Mineral raw material activated carbon

Mineral raw material activated carbon is mainly composed of live ores, which are mainly derived from the mining areas. The raw materials are screened and added with seafoam and bumpy soil, which greatly improves the adsorption performance of activated carbon.

2. Coconut shell carbon

Coconut shell activated carbon is mainly made from coconut shells from Hainan and Southeast Asia as raw materials, which are then screened, carbonized with water vapor and refined, and then made through a series of processes, such as removing impurities, activation and sieving. Coconut shell activated carbon is black granular, with developed pore structure and adsorption capacity, high strength, chemical stability, and long service life. Widely used in pure water, industrial water, drinking water, food and beverage, oil and power depth purification and refining of precious metals, with decolorization and deodorization, adsorption and removal of turbidity, and then zeolite, molecular sieve to use the effect is better.

3. Fruit shell carbon

Fruit shell carbon is mainly made of wood chips and fruit shells, and then carbonized, activated, processed, fruit shell carbon has a large surface area, high strength, developed pore structure, strong adsorption performance, and can effectively adsorb organic pollution and organic solvents in the water, applicable to pharmaceutical, petrochemical, sugar, beverage and other purification industries.

4. Wooden carbon

Wooden activated carbon is made of wood as raw material, which is in the form of powder, and processed through high temperature carbonization, activation and other processes, with large surface area, high activity, developed microporous, strong decolorization force and large pore structure, which can effectively adsorb colorful substances and impurities in the liquid.

The quality of activated carbon produced by Huamei is reliable and has a certain degree of competitiveness in the international market, with a stable export business. Welcome to contact us to get the price of different types of activated carbon products.
