Indoor formaldehyde pollution is more common after residential renovation. The data shows that after renovation, the formaldehyde in the house exceeds the standard by about 80%.
Second, the source of formaldehyde pollution
Furniture (bed/wardrobe/bedside table/coffee table/dining table/dining chair/sofa/shoe cabinet/desk, etc.). )
Furniture is the key pollution source of indoor formaldehyde, and a large number of adhesives-urea-formaldehyde resin (generated by the reaction of formaldehyde and urea) are used in the production of furniture plates. During the use of furniture, with the change of temperature and humidity, the adhesive constantly releases formaldehyde.
The pollution is serious, and the volatilization period is as long as 3- 15 years.
Decorative modeling and floor
The main pollution sources of formaldehyde are the plates used in house decoration (ceiling, TV background wall) and the floor laid in a large area.
Wallpaper, latex paint, etc
Adhesives used in wallpaper itself and wallpaper posting, wall latex paint, etc. Both contain formaldehyde.
Curtains, carpets and other soft decorations
Soft decorations such as curtains and carpets are also the focus of formaldehyde pollution control.
Third, the harm of formaldehyde pollution
Please pay more attention to these danger signs when there are small babies and pregnant women at home.
Cough, nasal discomfort
Feel eye irritation and tears.
I feel headache when I get up.
The child has obvious discomfort.
Indoor formaldehyde pollution is an important cause of childhood leukemia, and mothers should pay more attention!
Fourth, formaldehyde pollution control.
1. These aldehyde removal methods are useless!
1. 1 ? Photocatalyst can't effectively in addition to formaldehyde in practical application.
Photocatalyst was invented by the Japanese and widely used in sterilization, deodorization and mildew prevention in Japan. Its principle is: under the illumination condition, photocatalyst catalyzes water or oxygen in the air into hydroxyl radical and superoxide anion radical with strong oxidation ability, which can oxidize and decompose pollutants in the air into carbon dioxide and water. However, this kind of light is not ordinary light, but strong ultraviolet light. 30w ultraviolet lamp is generally used in the laboratory.
In real life,
[1] Strong ultraviolet rays cannot be reached indoors because they are harmful to human body. Therefore, in real life, photocatalyst can not effectively in addition to formaldehyde.
[2] When the tropical plateau is cloudless (with the highest ultraviolet intensity), the ultraviolet index is 15, the ultraviolet intensity of illumination is 3.75μW/cm2, and the ultraviolet intensity of 30W ultraviolet lamp is at least 100 μ w/cm2, so the ultraviolet of 30W ultraviolet lamp is ultraviolet.
The light intensity in cloudless sunny days is 26.7 times that in tropical plateau.
1.2 ? Put grapefruit peel and pineapple, and replace in addition to formaldehyde with air freshener.
These methods are all physical masking methods and belong to the method of deceiving the sense of smell. In fact, formaldehyde has not been removed, but the smell of pollutants is masked by the smell, which is not in addition to formaldehyde at all.
1.3 ? Formaldehyde in furniture cannot be sealed.
There is a method in the market to use the film-forming characteristics of sealant on the building surface to seal formaldehyde in the pollution source, thus reducing the indoor formaldehyde concentration. Formaldehyde is mainly released from uneven places such as cracks in plates.
It is difficult for this product to form a film on an uneven surface. In addition, the blocking agent does not react with formaldehyde, but only prevents the release of formaldehyde by physical means in a short time. Once the membrane is destroyed, formaldehyde pollution becomes more serious. Sealants outside in addition to formaldehyde are not practical.
1.4 ? Activated carbon and diatom mud can not completely remove formaldehyde.
Activated carbon and diatom mud belong to adsorption materials. The air purification principle of this kind of products depends on its developed pore structure and specific surface area. By contacting with air, it passively absorbs small molecules in the air and stores them, but it cannot treat pollutants by itself. The adsorption capacity of adsorption materials is limited, and it is easy to saturate, which will release pollutants for the second time. In practical application, it is not feasible to remove formaldehyde by this method.
1.5 ? The air purifier can't be in addition to formaldehyde.
The air purifier filters PM2.5 particles through a filter screen. But not except formaldehyde. CCTV channel has reported many times that the National Indoor and Indoor Environment and Environmental Protection Product Quality Supervision and Inspection Center has evaluated the performance of the 10 air purifier that sells well in the market. The results show that the air purifier is impossible to in addition to formaldehyde.

1.6 ? Biological enzymes can't, in addition to formaldehyde.
Biological enzyme products are mainly divided into plant extraction method and microbial method. Plant extraction is to remove formaldehyde by extracting corresponding substances from plants and reacting with formaldehyde nucleophilically and catalytically, such as amino acids, tea polyphenols and formaldehyde dehydrogenase. Microbial method is to spray microorganisms on the building surface, degrade itself or produce corresponding substances to react with formaldehyde to remove formaldehyde. However, the biological enzyme method requires high environment, and temperature, humidity and pH will all affect its activity. Secondly, this kind of substance is unstable and easy to decompose, which can not guarantee the long-term in addition to formaldehyde effect; Finally, the security of this method needs to be verified, because this technology is still in the research stage.
2. How to choose a reliable in addition to formaldehyde company?
2. 1 ? Look at the product: Is the product safe? Can formaldehyde be removed permanently and efficiently?
Is the product tested and certified by an authoritative organization as safe, harmless and non-irritating? Can the product quickly reduce the indoor formaldehyde concentration? Can the product continuously control the indoor formaldehyde concentration within a safe range?
2.2 ? Do you use testing instruments to deceive consumers?
2.2. 1 ? The most accurate formaldehyde detection method
Strictly speaking, the formaldehyde detection service provided by A in addition to formaldehyde Company itself is questionable. Indoor formaldehyde detection is a very rigorous work. Formal formaldehyde detection requires a third-party testing organization to use a special collector to sample the air on site, and bring the gas sample back to the laboratory for analysis and detection with professional equipment. A legally binding CMA report shall be issued after the test. This detection method is accurate in numerical value and rigorous in operation. But the price is too high for ordinary families to bear.
2.2.2 ? Common error detection methods in the market
In addition to the domestic formaldehyde detectors commonly used by formaldehyde companies, there are "six in one" and "eight in one". This kind of testing instrument is very unreliable, and even a glass tube of 0.5 yuan can't accurately judge the formaldehyde concentration. The most worrying thing is not the accuracy of the test data, but that many manufacturers don't know that the instruments designed and produced have the function of data adjustment, which means that no matter how they are tested, the data can be manipulated artificially. The test results are as follows.
What value? Therefore, this testing instrument is completely unreliable. This is a common way for in addition to formaldehyde companies to fool consumers.
2.3 ? How do we solve the problem of formaldehyde detection?
On the one hand, the truly legal and effective third-party formaldehyde detection service is very expensive, and the detection cost of ordinary families is about two or three thousand yuan. On the other hand, domestic testing instruments are not reliable. In line with the concept of respecting science, we don't want to be both a governance and a test, as well as a contestant and a judge. But consumers all hope that we can provide a cheap and convenient indoor formaldehyde concentration detection service. Let consumers have an intuitive understanding of formaldehyde concentration data before and after treatment.
In order to achieve this goal, we spent a year analyzing and comparing various portable formaldehyde detectors at home and abroad. Finally, through the introduction of the provincial quality inspection institute, we chose the Interscan formaldehyde detector imported from the United States and the Bright Chemical Air Sampler imported from Japan (used in conjunction with the Bright Chemical Formaldehyde Detection Tube).
These two imported instruments can accurately reflect the indoor formaldehyde concentration by repeatedly comparing with the third-party detection data. The import price of the two instruments is tens of thousands of yuan, and the daily consumables and maintenance costs are high. The American Interscan formaldehyde detector is the only formaldehyde detector in China that has passed the certification of China Institute of Metrology. It can provide consumers with relatively simple and cheap formaldehyde concentration detection service as a reference for indoor formaldehyde concentration.
If the customer requests a third-party authoritative organization to test, we will also recognize the test results and be responsible for the third-party formaldehyde test results after the professional formaldehyde purification service in grafton.
