What is the moisture removal function of activated carbon? How much water can be absorbed per 100g?

Activated carbon is made of charcoal, various shells and coal, and its adsorption is beyond doubt, so it is widely used in industrial waste gas treatment. Activated carbon can be divided into powder, granule and fiber according to its appearance. According to the different raw materials used, it can be divided into activated carbon (such as sawdust and charcoal) produced from plant raw materials. ), mineral raw materials (such as coal, petroleum coke, etc. ) and other raw materials (such as pulp, hydrolyzed lignin, waste plastics, etc. ); According to different manufacturing methods, it can be divided into gas activated carbon, chemical activated carbon and mixed activated carbon. According to the purpose, it can be divided into activated carbon for gas phase adsorption (such as solvent recovery activated carbon and desulfurization activated carbon). ), activated carbon for liquid phase adsorption (such as sugar activated carbon, monosodium glutamate activated carbon, water treatment activated carbon, etc. ) and activated carbon for catalysts or catalyst carriers.

Bamboo charcoal is a kind of high-performance activated carbon, and its adsorption capacity is 6 ~ 8 times that of ordinary activated carbon. For indoor pollution control, bamboo charcoal is a relatively new scheme. Compared with some chemical schemes (such as formaldehyde scavenger), it has no secondary pollution, low price, environmental protection and safety.

Bamboo charcoal is a kind of activated carbon, but the raw material is bamboo. It is made of anaerobic carbonization, with numerous small holes on its surface, which can effectively absorb a variety of floating substances and gases. The specific surface area of bamboo charcoal is as high as 700 m2/g, which means that the internal area of 1 g bamboo charcoal is equivalent to the size of a basketball court, and its adsorption capacity is 10 times that of charcoal. The charcoal bag filled with bamboo charcoal can quickly absorb the odor of the living room, and can also prevent insects, mildew and moisture. Suitable for decorating new homes, wardrobes, photographic equipment cabinets, rice tanks, etc.

It is worth mentioning that bamboo charcoal has a good adsorption effect on benzene chemicals such as paint. If you want to eliminate harmful gases such as formaldehyde, you'd better choose bamboo charcoal. Director Song said that before laying the floor, you can lay a layer of bamboo charcoal on the floor, and the effect is the same. In addition, bamboo charcoal has a good adsorption effect in a closed space, and it is more effective in furniture than in an open room.

After a period of use, the adsorption capacity of packaged bamboo charcoal will decrease. Director Song introduced a trick. When bamboo charcoal package is exposed in a ventilated place or the sun, its adsorption function will be restored.

Air purification is mainly aimed at the room space and the space of clothes and cabinets. The following is mainly divided into two parts to explain.

A, room space purification:

1, according to the authoritative test report, 1000g bamboo charcoal acts on 1 square unit space; Considering that the test environment is artificial, in real life, the factors that affect the efficacy of bamboo charcoal are far more complicated than the test environment, and are generally affected by ventilation conditions and building materials (wood, paint, etc.). ), room layout, etc. For example, if the ventilation conditions are good and the building materials are environmentally friendly, the corresponding consumption can be reduced, otherwise it needs to be increased. Therefore, in practical use, due to the comprehensive influence of the above factors, 100 g can be used as 65500 g.

2. Is the use of bamboo charcoal purification package centralized or decentralized? Generally, we advise buyers to place the sources of formaldehyde and benzene, taking into account the maximum coverage. If the pollution sources are scattered, it is recommended to put them in different places, aiming at multiple pollution sources (carbon bags with specifications above 500g are suitable for indoor space purification, and the specifications are 1000g, 1500g and 2000g in turn, so choose the product specifications that suit you according to the actual situation).

3. Where should I put it? If possible, it is recommended to put bamboo charcoal under the bed. No matter whether it is custom-made or finished furniture, harmful gases will be released, and the bed is one of the furniture that we contact for a long time in a day, which should be paid enough attention to. Dead corners of sofas and rooms, places where air exchange is not timely, are very easy to accumulate harmful gases, so we can focus on these positions.

Second, the purification of clothes and cabinets:

When decorating, everyone will order a lot of wardrobes and cabinets for fear that they will not be enough in the future, and the production bases of harmful gases such as formaldehyde and benzene are also these wardrobes and cabinets, so for decoration and purification, wardrobes and cabinets are one of our key goals.

1, wardrobe, because the space is relatively large and clothes are expensive to hang, it is recommended to use 500g purified charcoal bag;

2. Go to the wardrobe/pants cabinet, because the space is a little smaller, you can use 300g bamboo charcoal purification bag;

3. For closets with small space, you can use 200g bamboo charcoal to purify the charcoal bag;

4, drawers, or smaller cabinets, can use the specification of 100g bamboo charcoal purification charcoal bag;

5, shoe cabinets, shoe cabinets, although the space is not very large, but considering the heavy moisture of shoes, the amount of bamboo charcoal in shoe cabinets is more than that of cabinets of the same size. It is best to put a bag in each compartment, and at the same time, it is best to combine bamboo charcoal and shoe plugs for daily maintenance of shoes.

6. The above dosage is for reference only. If wood and glue are used more under the same ventilation conditions, the amount of bamboo charcoal will increase accordingly.

Third, when using bamboo charcoal to purify the space, it is recommended that you use it with bamboo vinegar to get better purification effect; Of course, you must remember that every 1 month or half a month, you can take the bamboo charcoal purification guards at home outside to dry for half a day, and then you can restore the efficacy.

Fourthly, the limitations of using bulk to purify granular carbon. Bulk granular carbon is suitable for use just after the house has been renovated and before moving in. It can be repackaged in a shoe box, and the mouth of the box can be covered with newspaper when the wind blows; Because there is carbon powder in bamboo charcoal particles, it will be produced in the production, transportation and use of bamboo charcoal, which is inevitable and extremely fine, and it is easy to raise, especially if it is impossible to purify wardrobes and cabinets with bulk granular carbon. If you are not careful, you will get your beloved clothes dirty, which is too uneconomical. For long-term use, it is convenient and reassuring to use the purified carbon package packaged by the manufacturer, because the fabric inside is breathable and leak-proof, and there is no need to worry about the leakage of carbon powder to pollute the things next to it.
