Activated carbon is a black porous solid carbon. Early made from wood, hard fruit shells or animal bones through carbonization and activation, and then converted to coal through crushing, forming or using uniform coal particles through carbonization and activation production. The main component is carbon, and contains a small amount of oxygen, hydrogen, sulfur, nitrogen, chlorine and other elements. Activated carbon is irregularly arranged in structure and has fine pores between cross-connects, which will cause defects in carbon structure during activation. Therefore, it is a kind of porous carbon with low packing density and large specific surface area. So how to buy activated carbon ? What are the brands? Let's check it out now.
ã€How to buy activated carbon】
1. High-quality activated carbon has high adsorption performance, many pores, relatively crisp and low density. In the case of equal weight packaging, the volume is even greater.
2. The particle size of high-quality activated carbon is generally about 0.5 mm. This particle size not only achieves the best performance, but also ensures that it is not a powder and no pollution. The weight of a pack is generally 30-50g.
3. The high-quality activated carbon package should ensure that the outer package is completely sealed, and the white breathable non-woven fabric bag is mostly used, and there is no dust to touch to ensure cleanliness.
4. After the high-quality activated carbon is put into the water, it will produce a series of extremely fine bubbles, and at the same time will emit a slight bubble sound. This phenomenon is often intense and lasts longer.

[How to use activated carbon reasonably to make it "universal"]
In view of the weakness of activated carbon in adsorbing formaldehyde, we can allocate the placement of activated carbon bags according to the season and different home locations, so as to make the imperfect activated carbon "universal". Generally, when using activated carbon in the three seasons of spring, summer, autumn and autumn, according to the pollution and ventilation, 1-2 months of ventilation should be used. In winter, especially in winter in the north, it is not recommended to use activated carbon alone. Agent products.
It should also be noted that more than 1 kg of activated carbon should be placed in a cubic meter space, and it should be replaced in time or periodically exposed to the sun to maintain its removal effect. It can also cooperate with planting certain green plants, such as Chlorophytum, aloe, green dill, etc., which can play a better effect.
Editor ’s conclusion: How to buy activated carbon and activated carbon brand are introduced here to remind friends, when activated carbon is used for a period of time, after the total amount of harmful molecules contained in its pores reaches the saturation value, then absorb harmful molecules It is easy to appear desorption state, in this case, we need to replace the activated carbon pack placed in the house in time.
