Is the effect of removing formaldehyde from grapefruit peel good 4hw.com.cn: the decorated houses are full of peculiar smell, formaldehyde and other harmful gases, and whether there is peculiar smell in the standard to judge whether to move in or not. Grapefruit peel contains volatile oil with fragrance, which can continuously volatilize fragrant gas in the room, covering up the peculiar smell in the newly decorated room, so many people mistakenly think that grapefruit can remove formaldehyde. Is the pomelo peel formaldehyde free? Let's have a look.
In fact, formaldehyde has not been removed at all, but the smell has been covered, so that everyone can not smell formaldehyde. The feeling is that formaldehyde is' absorbed '. Moreover, the pomelo peel does not remove formaldehyde is just, placed in the room will also let the formaldehyde concentration be higher. Because grapefruit peel contains more water, and then the water volatilizes into the air, the humidity in the room increases, and the formaldehyde emission and removal are inhibited, but the formaldehyde volatilization is more.
Tips: not only grapefruit peel is not effective, pineapple, vinegar water, tea and other local methods to deal with formaldehyde are not reliable, not only can not remove formaldehyde, increase indoor air humidity, but also increase indoor formaldehyde concentration.
The right way to remove formaldehyde
1. Ventilation method
Ventilation method is to open doors and windows for ventilation and remove formaldehyde through natural dilution. This is the most commonly used method to remove formaldehyde, and it is also the most effective method without side effects.
Disadvantage: time consuming.
2. Plant adsorption
The adsorption of plants can remove formaldehyde, especially Chlorophytum, aloe, tiger tail orchid and other flowers. However, when indoor air pollution reaches a certain level, plant adsorption will be a little inadequate. If you want to move into a new house in a hurry, it is obviously not appropriate for plants to take on the responsibility of absorbing harmful gases.
Disadvantages: not suitable for adsorption of high concentration pollution
Suitable for users: in addition to flower allergy, it is suitable for outdoor use, but it can not be used as the main force.
3. Activated carbon adsorption
Activated carbon can be said to be the best adsorption material in nature. It has the characteristics of many and dense pores and has a strong adsorption and decomposition effect on harmful substances such as formaldehyde. Generally speaking, the smaller the particles of activated carbon, the better the adsorption effect. Of course, what we need to remind seriously here is that we must buy the right activated carbon, and don't use bamboo charcoal and other things with very large gaps as activated carbon, otherwise it will certainly have no effect.
Disadvantages: it is easy for users to use bamboo charcoal and other miscellaneous carbons as activated carbons, which need to be replaced and dried after three or five days.
Suitable for users: all users are suitable.
4. Photocatalyst decomposition
The so-called photocatalyst is a kind of general name of photocatalysis materials with photocatalysis function represented by nanometer titanium dioxide. Under the action of light, it can produce strong catalytic degradation, effectively decompose harmful and toxic gases in the air, such as formaldehyde, and kill a variety of bacteria and fungi, and can decompose and harmless treat the toxins released by bacteria and fungi, At the same time, it has the functions of deodorization, anti pollution and air purification.
Disadvantages: high cost, UV light and other light are needed for the effect
Suitable for users: users with better economic conditions and home lighting conditions.
5. Chemical purification method
Chemical purification is a method to neutralize formaldehyde with chemical reagent or to block formaldehyde from volatilizing by chemical agent. Generally speaking, it is difficult to carry out the method of chemical reagent neutralization, which is easy to produce secondary pollution, while the method of preventing formaldehyde volatilization is to treat the symptoms rather than the root causes.
Disadvantages: the general operation is difficult, easy to produce secondary pollution, blocking the rule of law is not fundamental
Suitable for users: users in urgent need of formaldehyde removal, operated and used by professionals
6. Air purifier method
Air purifier method is to use air purifier to remove formaldehyde and other harmful substances in the air. This method of formaldehyde removal is similar to the activated carbon adsorption method, because the general air purifier uses the activated carbon filter to adsorb and filter formaldehyde and other toxic substances.
Disadvantages: it needs to be powered on and the filter should be replaced in time, which can not meet the environmental needs of new houses
Suitable for users: clean air in residential environment is more suitable
