Selection of activated carbon for air purification and its effect on water purification

The activated carbon for air purification uses high-quality wood or coconut shell. Through deep activation and unique pore size adjustment process, the activated carbon has rich pores, and the pore size is slightly larger than the toxic gas, with a specific surface area of more than 1300 square meters / g. the toxic and harmful gases such as benzene, formaldehyde and ammonia can be effectively adsorbed, which can be used to remove the gaseous pollutants and harmful gases in the indoor air Odor substances, and then achieve the purpose of reducing pollution and purifying the air. Now let's learn about the air purification activated carbon purchase methods and water effects.

Selection of activated carbon for air purification

1. The larger the volume is, the stronger the adsorption ability is In order to improve the adsorption function of activated carbon, as long as the pore structure is made on the activated carbon as much as possible, the more pores are, the more crisp the activated carbon is, the lighter the relative density will be, so the handle of good activated carbon will be lighter, and under the condition of equal component packaging, the volume of good activated carbon will be much larger than that of residual activated carbon.

2. Shell carbon coconut shell carbon, high iodine value is good carbon. Activated carbon purification gas depends on adsorption ability, here is an important indicator of adsorption ability - iodine value, the higher the iodine value, the stronger the adsorption ability. The hot stir fry is coconut shell carbon, but the iodine value of some non activated coconut shell carbon may not reach 500. And the iodine value of air purification special high-grade fruit shell carbon of Haixin can reach 800-1200, which can reach the effect of first-class brand air purification carbon by adsorption. In addition to some well-known brands with certified effects, we should ask the seller to present the statement of iodine value inspection when purchasing most other air purification carbon.

3. The air permeability of the carbon bag is very important. Put the carbon bag on the mouth to blow. If the gas can easily pass through the carbon bag, the air permeability of the carbon bag is outstanding. If the charcoal can't be blown, it's hard for the air to pass by, and it's hard for the best charcoal installed there to have a great effect. As a forced adsorption product, it is necessary for the air to penetrate into the deep layer of the carbon bag, so that the carbon bag can play an outstanding role in air purification and adsorption. In theory, the best way to pass the air is to pull the carbon bag open and put the carbon directly in the tray. Of course, this way has certain impact on the environmental health.

4. Bamboo charcoal is not activated charcoal. Bamboo charcoal is a very excellent healthy household product. Pillows and insoles made of bamboo charcoal fiber are all very good products. The emphasis of each product is different. Bamboo charcoal can adjust the humidity of space only when it has certain adsorption on the moisture. However, the aperture of bamboo charcoal is rare and iodine value is low, so it can not be used as a harmful gas purification product. Its pore size is very weak to capture harmful gases, and it can not firmly absorb the captured formaldehyde molecules.

5. Activated carbon is not all-around. If drugs are used to decorate pollution management products, then activated carbon is more like traditional Chinese medicine and formaldehyde eradicator is more like western medicine. One pays attention to scheduling but has a slow effect, and the other is successful but cannot be eradicated. Cooperation between the two products is the best deployment. Generally, in spring, summer and autumn, the use of activated carbon alone needs to cooperate for 1-2 months according to the pollution and ventilation conditions. In winter, especially in the north, it is not recommended to use activated carbon alone. It is necessary to cooperate with some formaldehyde scavenger products aimed at pollution sources. In general, during management and construction, the management organization will first use formaldehyde eradicator to eliminate most of the pollution sources, and the remaining pollution sources will be separated and the slight overspending will be handed over to the air purification carbon for treatment.

Water effect of activated carbon Activated carbon can remove smell and taste, chroma, residual chlorine, colloid, organic matter (synthetic detergent, pesticide, herbicide, insecticide, synthetic dye, trihalomethane, haloacetic acid, endocrine disruptor such as PAEs, etc.), heavy metals (such as mercury, silver, cadmium, chromium, lead, nickel, etc.), radioactive substances, etc., and it is the earliest and most widely used clean water in the water purifier Material Science. Activated carbon is not only used in ordinary activated carbon water purifiers, but also in household reverse osmosis water purifiers, as well as in most ultrafiltration, ceramics, KDF, UV water purifiers. Activated carbon and KDF can remove the residual chlorine in water, but KDF and chlorine react to form zinc ions (Zn2 +, which may lead to over expenditure of zinc in water, while there is no such concern when using activated carbon to remove chlorine. In the process of activation, activated carbon forms many kinds of micro pores with various shapes, forming a huge surface area with adsorption effect. Its specific surface area is 500-1200m2 / g. the larger the specific surface area, the better the adsorption effect.

It is hoped that the introduction of the above information about the selection method of air purification activated carbon and the effect of activated carbon water will be helpful to us. Air purification activated carbon is a kind of cylindrical activated carbon. High quality activated carbon is specially treated for purifying polluted air. Only activated carbon with high hardness, high strength and microporous pores can be used as air purification carbon. Shell carbon and coal can be used as carbon materials for air purification. The effect of coconut shell activated carbon is the best.
