  • Detail

Home decoration will cause more or less pollution. At present, formaldehyde is the main pollutant in newly decorated homes in China, and formaldehyde is an important part of adhesives. Therefore, all adhesives, including wood-based panels, coatings, carpets, and furniture, will contain formaldehyde. Therefore, the pollution of formaldehyde after decoration is very serious, and formaldehyde is also very harmful to human health. The treatment of decoration formaldehyde is a hot issue that people are concerned about. As we all know, placing some plants indoors can absorb formaldehyde and reduce indoor formaldehyde concentration, which is the best way to treat formaldehyde in decoration at present. So, which plants absorb formaldehyde most easily? Now let me reveal the answers for you one by one

As we all know, placing some plants indoors can absorb formaldehyde and reduce indoor formaldehyde concentration, which is the best way to treat formaldehyde in decoration at present. So, which plants absorb formaldehyde most easily? Now let me reveal the answers for you one by one

source of formaldehyde pollution

with the development of economy and the improvement of people's living standards, building decoration materials made of various raw materials have entered the family. The chemical formaldehyde is recognized as the representative of indoor air pollution. The building decoration materials that cause formaldehyde pollution and other reasons are:

1. Decoration materials and new composite furniture are the main sources of formaldehyde pollution. Formaldehyde is released when the adhesives of plywood, large core board, medium fiber board and particleboard (particleboard) in decoration materials and furniture are heated and deliquescent, which is the main indoor formaldehyde emission source

2. UF foam is used as the insulating material of the house to prevent heat and cold. Under the action of light and heat, foam ages and releases formaldehyde

3. Coatings, chemical fiber carpets, cosmetics and other products with formaldehyde as preservative

4. Indoor smoking. Each cigarette smoke contains 20-88ug of formaldehyde and has a synergistic effect of carcinogenesis

harm of formaldehyde pollution

formaldehyde is a highly toxic substance, ranking second in the list of priority control of toxic chemicals in China. Formaldehyde has been identified by the World Health Organization as a carcinogen and teratogenic substance. It is recognized as a source of allergy and one of the potential strong mutagens

studies have shown that formaldehyde has strong carcinogenic and cancer promoting effects. A large number of literature records that the effects of formaldehyde on human health are mainly manifested in abnormal smell, irritation, allergy, abnormal lung function, abnormal liver function and abnormal immune function. When its concentration reaches 0.06 -0.07 mg/m3 per cubic meter of air, children will have mild asthma. When the formaldehyde content in the indoor air is 0.1 mg/m3, there is peculiar smell and discomfort; When it reaches 0.5 mg/m3, it can irritate eyes and cause tears; Reaching 0.6 mg/m3 can cause throat discomfort or pain. When the concentration is higher, it can cause nausea and vomiting, cough, chest tightness, asthma and even pulmonary edema; When it reaches 30 mg/m3, it will immediately cause death

long term exposure to low-dose formaldehyde can cause chronic respiratory diseases, nasopharyngeal carcinoma, colon cancer, brain tumors, menstrual disorders, gene mutations in the nucleus, DNA single strand interconnection and DNA protein interconnection, inhibit the repair of DNA damage, pregnancy syndrome, cause chromosomal abnormalities in newborns, leukemia, and cause memory and intelligence decline in adolescents. Among all contacts, children and pregnant women are particularly sensitive to formaldehyde, and the harm is even greater

decoration formaldehyde treatment methods

1. Formaldehyde removal by physical adsorption technology

is mainly a variety of air purifiers. Some manufacturers in China have produced purifier products, but most manufacturers still produce mechanical filtration, ozone and air anion generators. This kind of products mainly adsorb suspended solids in the air, and also have a certain adsorption effect on indoor formaldehyde and other pollutants

(1) air purifier: it has a certain adsorption effect on indoor formaldehyde and other pollutants

(2) Mayan blue material: with countless tiny pores and weak electricity, it can absorb and lock a large number of harmful molecules such as formaldehyde and toluene, and decompose them into harmless gases. It is an excellent formaldehyde removal material

(3) harmful gas adsorber, furniture adsorption treasure: it can catalyze the decomposition of indoor formaldehyde and other harmful gases

(4) deodorant and formaldehyde trapping agent: used in decoration projects, it can effectively reduce free formaldehyde in wood-based panels. The commonly used method is to spray formaldehyde scavenger or formaldehyde trapping agent in the indoor air, or use some agents that can immediately remove odor. These methods can only remove free formaldehyde, and cannot be effective on the formaldehyde released from fundamental artificial boards. Another kind of formaldehyde removal method adopts the principle of sealing, which is directly used on the surface of furniture. After using this formaldehyde scavenger, there will be a transparent or bright white film on the surface of furniture. Although the sealing method has an immediate effect, there will also be loopholes in the long-term sealing, which cannot fundamentally remove formaldehyde

(5) formaldehyde sealer: apply it to the interior wall panels and wood-based panels of furniture without paint treatment to reduce formaldehyde emission

2. Catalytic technology for formaldehyde removal

catalytic technology is also known as cold catalyst technology. It is mainly multi-component heterogeneous catalysis, combined with ultra-fine filtration, so as to ensure that a variety of harmful odorous gases are decomposed into harmless and odorless substances at room temperature and pressure, from simple physical adsorption to chemical adsorption, which improves the type, adsorption efficiency and saturation capacity of adsorbed pollution particles, and does not produce secondary pollution, Moreover, the service life of the adsorption material is more than 20 times that of ordinary materials, which is highly targeted and can catalyze the decomposition of indoor formaldehyde and other harmful gases

3. Chemical neutralization technology removes formaldehyde

at present, some experts have developed various deodorants and formaldehyde trapping agents. These products generally use complex technology to destroy the molecular structure of harmful gases such as formaldehyde and benzene, neutralize the harmful gases in the air, and then gradually remove them, finally achieving the goal of improving indoor air quality. But we should pay attention to the timing of use. It is best to use it in combination with decoration projects, which can effectively reduce the free formaldehyde in wood-based panels

4. Plant formaldehyde removal

(1) Chlorophytum comosum
