Application and question and answer knowledge of coconut shell activated carbon

Coconut shell activated carbon is mainly used for purification of drinking water, pure water, wine, beverages, industrial sewage, decolorization, dechlorination and deodorization; it can also be used in desulfurization of oil refining industry. The modified activated carbon has a good removal effect on harmful substances and odors such as benzene (diphenyl, triphenyl), formaldehyde, phenol, hydrazine, ammonia, TVOC, etc., and the adsorption efficiency and adsorption amount of coconut shell activated carbon are required. It is superior to other types of activated carbon and is safe, non-polluting and has no side effects.

Coconut shell activated carbon packaging instructions: 25 kg / bag, with an intimal sealed bag can also be customized.

The adsorption capacity of activated carbon has a certain relationship with the level of water temperature and the quality of water. The higher the water temperature, the stronger the adsorption capacity of activated carbon; if the water temperature is above 30 °C, the adsorption capacity reaches the limit and there is a possibility of gradual decrease. When the water quality is acidic, the adsorption capacity of activated carbon for anionic substances is relatively weakened; when the water quality is alkaline, the adsorption capacity of activated carbon for cationic substances is weakened. Therefore, the pH of the water is unstable, which will also affect the adsorption capacity of activated carbon. . ○ Beijing coconut shell activated carbon deodorization effect ○ coconut shell active coconut shell activated carbon is much higher than coal-based activated carbon, and the finished activated carbon material is generally not easily recognized by the general public.

1. Air purification: for example, coal-based columnar activated carbon is used to recover solvent from air containing solvent vapor; coal columnar activated carbon filtration is used to deodorize air; used in gas masks and industrial respirators to protect against poisons.

2. Sewage treatment site exhaust adsorption

3, beverage water treatment

4, power plant water pretreatment

5, pre-treatment of wastewater recycling

6, biological sewage treatment

7. Toxic wastewater treatment

8. Petrochemical alkali-free desulfurization

9, solvent recovery (because coal columnar activated carbon can adsorb organic solvents)

10. Chemical catalyst carrier

11, canister

12, gold extraction

13, chemical storage exhaust purification

14, sugar, alcohol, monosodium glutamate medicine, food refining, bleaching

15, ethylene desalted water filler

16, car exhaust purification

17. PTA oxidation unit purifies gas

18, printing ink removal

19. Gas separation: for example, recovery of benzene from city gas; recovery of gasoline, propane and butane from natural gas; treatment of exhaust gas in Fischer-Tropsch synthesis to recover hydrocarbons therein.

20, liquid phase adsorption: for example, in the sugar industry, the use of coal columnar activated carbon adsorption method to decolorize the sugar liquid; in the chemical industry with coal columnar activated carbon to decolorize the organic matter; use coal columnar activated carbon to purify the organic impurities in the plating bath In order to ensure the quality of the plating surface and for the dephenolization of wastewater.

Q&A on coconut shell activated carbon:

What is the validity period of the original ecological coconut shell activated carbon?

A: Except for the special use of wooden floor, the validity period is 5-8 months, and the unopening is 3 years. During the use, 30 days (ie one month) is used to expose the sun for 3-5 hours.

Special for wooden floor covering: valid for 25 years.

How long does it take to Remove Formaldehyde at home?

A: It depends on the degree of pollution of the house decoration. Generally, the mild (formaldehyde exceeds 1-3 times) pollution will take effect within 3 days, plus window ventilation; if it is seriously polluted, it will promote comprehensive management. Coconut shell activated carbon plus air purifier.

Is there any production standard for indoor high-efficiency coconut shell activated carbon adsorbent?

A: According to GB/T18883 indoor air quality standard, and this product meets Q/XSHG 002-2002 technical standard.

After the original ecological coconut shell activated carbon is used for a period of time (30 days), why should it be exposed to the sun? What is the principle?

A: The water is exposed to moisture, not harmful gases. The gas-phase coconut shell activated carbon is an adsorbing gas. It is very powerful and easy to adsorb water vapor.

Why is the best way to control indoor formaldehyde pollution is to use coconut shell activated carbon and open window ventilation?

A: Because the structure of coconut shell activated carbon is characterized by many pores and strong adsorption capacity, many disinfection masks are made by utilizing the characteristics of coconut shell activated carbon. It is best to choose coconut shell activated carbon with smaller particles. The smaller the particles, the better the adsorption effect. Generally, the newly renovated living room uses coconut shell activated carbon at a dosage of 1 pack (50g) per square meter. Coconut shell activated carbon is easy to use, not only can adsorb formaldehyde but also adsorb other polluting gases, and it will not cause secondary pollution. The second is to open the window frequently to enhance the convection of indoor and outdoor air, and the effect is very good. (The answer is reproduced from "The best way to remove formaldehyde with coconut shell activated carbon" - the relevant scavengers on the market are not cured.

Physical method Comparison (or difference) between coconut shell activated carbon method and chemical treatment method?

A: The original ecological coconut shell activated carbon belongs to physical adsorption to control pollution.

The principle of products such as formaldehyde scavengers belongs to chemical adsorption. The characteristics of chemical adsorption are: first, irreversible, that is, products cannot be recycled, and second, chemical adsorption produces new compounds, new substances, which may cause environmental pollution. Secondary pollution.

The charcoal pollution control product represented by coconut shell activated carbon belongs to the physical adsorption. The first characteristic of physical adsorption is that it can be reversed. There is a process of adsorption and desorption. Taking coconut shell activated carbon as an example, after sun exposure It can be reused many times! The second is that in the physical adsorption, the adsorbed material does not undergo any chemical reaction, that is to say, there is no possibility of secondary pollution.

The chemical adsorbent can absorb harmful substances in the room in a very short period of time, especially harmful gases with short release period such as benzene and ammonia, and the effect is obvious in a short period of time. But the release cycle of formaldehyde is 3-15 years, which is a long-term process. So far, there is no way to prevent the release of formaldehyde, and chemical adsorbent products are disposable, and can not be recycled by themselves, so it is not suitable for long-term formaldehyde treatment, but only suitable for short-term strengthening of formaldehyde treatment. Coconut shell activated carbon can be recycled for a long time, and it always maintains adsorption to formaldehyde, which is the best solution for treating formaldehyde.

Does opening the window have any effect when using the original coconut shell activated carbon product?

A: No impact. Due to the static adsorption of coconut shell activated carbon, window ventilation accelerates the indoor air flow, but accelerates the adsorption of coconut shell activated carbon and increases the adsorption rate. This is more effective, so the window ventilation does not affect, it is recommended to use the coconut shell activated carbon at the same time to open the window ventilation.
