Interpretation of pollution sources - indoor decoration pollution is mainly formaldehyde pollution, and the main release source of formaldehyde is the place where large fiber board and core board are accumulated.
Note: If the emission of harmful benzene such as formaldehyde benzene in the room is greater than the adsorption amount of activated carbon, then only increase the amount of activated carbon, or adopt comprehensive management methods. Otherwise, it can only alleviate the original symptoms and fail to achieve the desired. effect!
If the emission of harmful benzene such as formaldehyde benzene in the room is greater than the adsorption amount of activated carbon, then only increase the amount of activated carbon, or adopt comprehensive management methods. Otherwise, it can only alleviate the original symptoms and achieve the desired effect!
First, the quality of activated carbon.
1. The quality of activated carbon bought by different people is different, so the effect is different. Such as bamboo charcoal, low-adsorption coal columnar charcoal, industrial carbonized materials (a few yuan a kilogram!), carbon carving and other low-quality charcoal is not suitable for indoor pollution control. Because some of the first activated carbon depends on the brand, look at the manufacturer.
How to choose authentic high quality household formaldehyde to remove formaldehyde
How to buy authentic high quality activated carbon
In recent years, activated carbon has been improved to improve the adsorption capacity of toxic and harmful gases such as formaldehyde, benzene and ammonia, and is increasingly favored by consumers. So how can we buy authentic high-quality activated carbon? The following is a "six look" to help you buy.
A look: company business license
1. From the scope of business: determine whether it is a direct manufacturer, or a trading company or a leather bag company.
2. From registered capital: judge whether it is a big company or an individual small company
3. From the date of annual inspection: judge whether to close the company or operate without a license.
Second look: quality inspection report
1. From the authority of the testing organization: judge whether the national environmental testing center is appraised.
2, stamped from the testing agency: to determine whether there is qualification. With MA, AL
3. Test results from testing institutions: Determine the rate of formaldehyde, benzene, and removal of activated carbon.
Note: The weight of activated carbon is the same, it is comparable.
Third look: enterprise production execution standards
All regular activated carbon production enterprises must have product production standards and be filed by the State Bureau of Quality and Technical Supervision.
Fourth look: quality management system certification
All regular activated carbon production enterprises have strict quality management and must pass ISO quality management system certification.
Five look: product technology content
1. Is there a high-tech enterprise certification?
2. Whether the activated carbon produced is internationally advanced, leading domestically, and won the national “patentâ€.
3. Whether it is strong alliance with the world's carbon giants and has a strong technical backing.
In short: consumers should pay attention to identify activated carbon charcoal, charcoal, coconut shell charcoal and other carbonized materials when purchasing activated carbon; secondly, it is not possible to equate low-adsorption carbon carving, ordinary activated carbon and high-quality activated carbon, and not to be marketed. The deceptive advertising language is flickered, such as: silver-loaded activated carbon in addition to formaldehyde, benzene series; catalyst activated carbon decoration pollution. It is best to buy from regular manufacturers. According to the "six look" principle, look for purchases in case you are deceived.
Second, the degree of pollution is different, so the effect is different
How to use activated carbon, the effect is better?
1, reference dosage
Newly renovated living rooms (including office space, hotels, etc.) are used at 1-2 packs per square meter (ie 50-100g). The daily protection of the indoor environment can be appropriately reduced according to the degree of pollution.
Note: 50-100g per square meter is used to calculate the total amount of space used, not to evenly place 50-100g per square meter.
2, usage:
A. The key place is the source of pollution and the place where people often move. The activated carbon adsorption package is directly placed in the cabinet of the wardrobe, shoe cabinet, book cabinet, kitchen cabinet, etc. in the living room; the computer, the desk, the coffee table, the sofa, and other places where people often move, and any other places that need to purify the air. Activated carbon is a passive purification material. The harmful substances in the air must rely on air as a medium, but the air mobility in the room is poor. The activated carbon is difficult to capture harmful substances in the air far away in a short time, so it is used in a small range. Small spaces work best.
B. The height of the space is 180 cm. Indoor harmful gas, taking formaldehyde as an example, its specific gravity is greater than air, so the pollutants in the middle and lower parts of the indoor space are the most serious. This height is equivalent to the height of the human body, so it is the best placement height.
C. After about 20 days of use, after 3-5 hours of exposure in the sun, it can be used repeatedly, so it can be used for 6-10 months. This step is necessary. The pores in the activated carbon are limited and will be saturated after a period of use. In particular, a large amount of water molecules occupy a large space in the activated carbon. Therefore, it is necessary to explode on a regular basis to evaporate water molecules in the activated carbon.
D. Use of new homes that do not stay immediately: first open the windows to ventilate as much as possible. You can use an electric fan to speed up the alternating amount of fresh air and indoor air, discharge harmful gases to the outside, and disperse the activated carbon adsorption pack anywhere in the room. After a period of time, the indoor odor is alleviated, and the activated carbon is collected and placed in a centralized manner to control the source of pollution and continuously adsorb harmful substances that are continuously released. When the activated carbon is placed in the cabinet, the door should be closed and the window opened.
E, the need to stay in the new house to pay attention to: the emission of harmful gases such as formaldehyde benzene is greater than the adsorption of activated carbon, then only increase the amount of activated carbon, otherwise, can only alleviate the original symptoms, the effect is slightly slow, but safe Side effects, long-lasting purification time. For new homes that are urgently needed, it is recommended to use them in combination with other treatment methods, such as using air purifiers, formaldehyde benzene scavengers, and planting plants such as spider plant, tigertail orchid and aloe.
The comprehensive treatment in the middle reaches the desired effect.
