First, packaging: the packaging is breathable and firm, and it will not affect the cleanliness of the new house if it is placed in a place that needs purification and deodorization.
Second, the charcoal bag: the particles are fine and the charcoal bag is full. It is suggested that 50g per bag is the best.
4. Placement of activated carbon charcoal bag: 50g packed charcoal bag can be directly placed in various places in the home that need purification, such as living room, cupboard, drawer, wardrobe, bathroom, bedroom, etc. There is no need to disassemble the small charcoal bag, and the height is suggested to be lower than 1m!
3. Selection of activated carbon: Coconut shell activated carbon is refined from high-quality coconut shell through a series of production processes. The appearance of coconut shell activated carbon is black, including granular and columnar, which has the advantages of developed pores, good adsorption performance, high strength, easy regeneration, economy and durability. Mainly used for removing aldehyde and odor in new house decoration.
4. How long will it take: Generally, the new house will take effect in 7 days, and it will be basically demolished in 2 weeks. But formaldehyde is constantly released. Long-term use is recommended. Can be used in the sun 1 5min 1 month, and can be used continuously1year.
5. 1 How many square meters is appropriate: 2,000 g of fresh-breathing coconut shell activated carbon is suitable for a new house of 60 square meters, and small carbon bags can be directly placed in various positions that need to be purified, keeping the doors and windows ventilated, and the purification area is much larger than the housing area. In addition to formaldehyde deodorizes better and faster.
Question 2: How to choose good activated carbon is only suitable for short-term odor removal and dehumidification. The best way for a newly renovated house is to open the window and ventilate for 2 weeks-1 month. If there is no pollution exceeding the standard, you can move in. If there are polluting volatile gases, such as formaldehyde, which are released for a long time, it is necessary to find a pollution source to replace and update. Activated carbon has a strong ability to absorb organic vapor, but in most cases, it can't decompose formaldehyde. ...
Question 3: Which activated carbon is good, how to choose which activated carbon is good, and how to choose it.
The quality of activated carbon can not be generalized, mainly according to different uses to choose different activated carbon. Compared with coconut shell activated carbon, coconut shell activated carbon is better, with higher strength and adsorption value. When selecting coconut shell activated carbon, on the one hand, we should determine the particle size, on the other hand, we should look at the purity of coconut shell activated carbon. Coconut shell activated carbon has its own thickness, and it is irregular and granular after crushing, and its section is bright. The other is the adsorption performance of coconut shell carbon. You can put a transparent cup in water and activated carbon particles in water, and you can see thin-line bubbles escape from the water. The more lines, the longer the duration and the better the quality.
Question 4: How to choose activated carbon and use it correctly? According to the family size, it is generally per square meter 1-2 packs. If the indoor environment is poor, you can consider using it more. The effective time of activated carbon is about 6 months. After being opened for about 20 days, it can be exposed to the sun for 2-3 hours, patted several times, recovered and reused.
Question 5: What kind of activated carbon is good and how to choose it depends on the specific application direction!
Household in addition to formaldehyde: It is recommended to choose coconut shell activated carbon with high iodine value;
Decolorization of food and medicine: it is recommended to choose wood flour activated carbon, medicinal activated carbon and 767 activated carbon.
Enterprise air filtration and adsorption: it is recommended to choose coal-based activated carbon with high iodine value, columnar and granular, which has high cost performance;
Water treatment field: you can choose powdered activated carbon, fruit shell activated carbon, coal-based activated carbon, coconut shell activated carbon and so on!
Question 6: How to quickly identify the quality of activated carbon? Look at the volume first: activated carbon has strong adsorption because it has many pores. The more pores, the more brittle and light activated carbon will be. Therefore, the activated carbon with good quality will feel lighter, and the activated carbon with good performance will be much larger than the activated carbon with poor quality under the same weight packaging.
Second, choose activated carbon with your tongue. Because activated carbon is non-toxic, you can make it into small particles so that its broken section is exposed. Then put the cross-sectional activated carbon on the tip of the tongue, and you can feel an adsorption force. Good quality activated carbon can even hurt your tongue and dry the water, while activated carbon without adsorption is either of poor quality or wet.
Third, in addition, you can also do a bubble experiment. Put a handful of activated carbon into the water, and the water will gradually penetrate into the pores of the activated carbon, forcing the air in the pores to be discharged, thus producing a series of extremely fine bubbles, drawing a fine bubble line in the water and making a hissing bubble sound. The stronger this phenomenon occurs and the longer it lasts, the better the adsorption of activated carbon.
Question 7: How to choose and distinguish activated carbon with good activated carbon quality from black and dull activated carbon?
The quality is generally not too heavy.
The texture is dense, and tiny holes can be observed.
Question 8: Selection of household activated carbon: Activated carbon is an internationally recognized universal adsorbent. Expert tip: Activated carbon adsorption method is the most extensive, mature, safest, most reliable method to remove indoor pollution and has the most kinds of adsorbed substances. As an excellent physical and chemical adsorbent, activated carbon has attracted more and more attention. Efficient and environmentally friendly activated carbon bag can adsorb all indoor harmful gas molecules, such as formaldehyde, ammonia, benzene, xylene, radon and so on. In the air, quickly eliminate the decoration odor and evenly adjust the space humidity. It has a good effect on living rooms, furniture wardrobes, bookcases, shoe cabinets, shoes, refrigerators, bathrooms, floors, fish tanks, cars, air conditioners, computers, offices, hotels, entertainment places and Diagrams. So how can we choose to buy high-quality activated carbon? Iodine value: Iodine value is a performance difference of activated carbon. The iodine value of fruit shell, bamboo charcoal and coal ranges from several hundred to more than one thousand, and the iodine value of activated carbon ranges from 800, 850, 900, 950, 1000,100,1200mg, etc. The cost and price are different! Activated carbon made of raw materials of the same material can be simply distinguished by the weight per unit volume: As mentioned above, in order to improve the adsorption performance of activated carbon, only the pore structure should be made on the activated carbon as much as possible. The more pores, the more brittle and lighter the relative density of activated carbon, and the better activated carbon will feel lighter. In the case of packaging with the same weight, the volume of activated carbon with good performance will be much larger than that of inferior activated carbon. Look at the bubbles: put a handful of activated carbon into the water. Due to the infiltration of water, water will gradually immerse into the pore structure of activated carbon, forcing the air in the pores to be discharged, thus producing a series of extremely fine bubbles, drawing a fine bubble line in the water and making a little bubble sound at the same time, which is very interesting. The stronger this phenomenon occurs and the longer it lasts, the better the adsorption of activated carbon. Look at decolorization ability: another performance of activated carbon adsorption ability is decolorization ability. Activated carbon has the magical ability to turn colored liquid into light color or colorless, which is actually caused by the adsorption of pigment molecules in colored liquid by activated carbon. It is precisely because of this characteristic that activated carbon is widely used in the production process of converting brown sugar into white sugar in sugar industry. Take two transparent cups, put purified water in one cup, and then drop a drop of red ink (here you can use any pigment that is easy to observe but does not change the nature of water, such as blue ink and printer color ink, but you can't use ink or carbon ink). After stirring evenly, pour half of the colored water into another cup for comparison. Put activated carbon into colored water, the dosage should reach half or more than half of water, and the effect will be obvious. 10D20 after standing for 20 minutes, compared with the control water sample. Under the same conditions, the stronger the decolorization effect, the better the adsorption of activated carbon. Although there are many varieties of activated carbon in appearance and use, they all have a similar characteristic, that is, "adsorption". Activated carbon has adsorption function because it has developed pore structure. Just like the sponge we see, under the same weight, the sponge can absorb more water than other objects because of its developed pore structure. However, the pore structure of activated carbon is invisible to the naked eye, because they are only between1×10-12 mmd10-5 mm, which is not much larger than a molecule. The developed degree of activated carbon pores is unimaginable. If we take 1g activated carbon and expand all the pore walls into a plane, the area will reach 1000 square meters (that is, the specific surface area is 1000g/m2)! The main factors affecting the adsorption of activated carbon depend on the developed degree of internal pore structure. Only a large number of activated carbon with pore size slightly larger than the molecular diameter of toxic and harmful gases can have strong adsorption capacity. In order to meet this requirement, the material selection and processing (pore-making and activation) of activated carbon are extremely strict. Activated carbon completely conforms to gas phase adsorption, with particle size of 20-40 meshes, huge specific surface area, developed internal voids, low density, light hand feeling, strong bubble phenomenon, large weight and volume, which can effectively purify indoor air. It can adsorb odorous, toxic and various harmful gases in the air, especially formaldehyde, benzene series, TVOC, CO (carbon monoxide), NH3 (ammonia oxygen), O3 (ozone) and CL2 (chlorine) in the air. Widely used in decontamination, filtration, air conditioning decoration.
