Question 2: What are the main pollutants after renovation? Formaldehyde and TVOC are very harmful to human body.
The decoration is finished, so deal with it. You can try the pollution control treasure decorated by Khufu when you check in.
Question 3: What are the symptoms of decoration pollution? Formaldehyde has a strong carcinogenic and cancer-promoting effect, and even death. You can explain it in the following ways:
1. Milk can degrade and leave the site quickly. Lie still, keep warm and take oxygen when necessary. After inhaling a lot of formaldehyde vapor in a short time, those who have upper respiratory tract reaction should be observed for at least 24 hours to avoid aggravating the condition after the activity. Observe carefully to prevent pulmonary edema. Glucocorticoid can be used early when necessary. Symptomatic treatment, treatment of complications, prevention of infection. Ventilation for 5-7 days after renovation, and then pollution control.
2. Pollution control This piece can generally use Maya blue to remove formaldehyde, and there are tiny pores that can contain harmful gas molecules such as formaldehyde and toluene, plus ventilation.
3. Plants that absorb formaldehyde are cactus, chlorophytum, reed, ivy, cycad and so on. Natural odor absorption, no secondary pollution. However, the number of places determines the effect of odor absorption, and the adsorption speed is slow and the autotrophic survival rate is low.
Question 4: What are the pollution of home decoration? Formaldehyde comes from MDF, paint, wallpaper, adhesives, paints and other decoration materials, and its release process is very slow, lasting for three to fifteen years and cannot be changed. There are many methods in in addition to formaldehyde, so you can choose a suitable one: 1, ventilate frequently, and reduce the indoor formaldehyde concentration as much as possible. 2. You can raise some plants in in addition to formaldehyde, such as chlorophytum, ivy, green radish, pueraria lobata, Fugui tree, Huwei orchid, agave, Eupatorium odoratum, tortoise shell bamboo, Gerbera jamesonii, cycad, etc. 3, you can buy some Maya blue and put it indoors, which has a very good effect of purifying odor and adsorbing formaldehyde. Photocatalyst wood essential oil can be brushed on the wardrobe. 4. You can also eat some foods that prevent formaldehyde. Among the vegetables we often eat, there are also many detoxification functions. For example, tomatoes are sweet and cold, and have obvious effects of clearing away heat and toxic materials, diuresis and detumescence, resolving phlegm and quenching thirst; Luffa is sweet in taste and cold in nature, and has the functions of clearing away heat and cooling blood, detoxifying and activating blood; Cucumber and bamboo shoots can clear away heat and induce diuresis; Celery can clear away heat and promote diuresis, cool serum and liver fire, and has the effect of lowering blood pressure.
Question 5: What is the main pollution of interior decoration? Formaldehyde pollution comes from adhesives used in various wood-based panels, such as chemical fiber carpets, paints, coatings, detergents, indoor pesticides, disinfectants, preservatives, paper, textile fibers and other chemical products. Especially in wardrobes, whole kitchens and newly bought furniture rooms, wood-based panels should be installed, and even the tenons and mortises of pure solid wood furniture should be bonded with white latex. White latex is still inseparable from formaldehyde, but the formaldehyde in slightly quality building materials and slightly quality furniture is more serious.
1. wall
At present, most family walls are painted with water-based paint, instead of paint containing formaldehyde and benzene pollution, thus avoiding the source of formaldehyde pollution. However, friends who use wallpaper as a wall must pay attention. What is the wallpaper attached to the wall? You know ~ ~ ~
2. Wardrobes, cabinets and other furniture
Wardrobe, cupboard, etc. Most of them use particleboard veneer, but also need to transfer the right amount of glue, so wardrobes, cabinets and so on. It also emits formaldehyde.
Many synthetic woods need glue during processing, and the glue contains formaldehyde. Like leather furniture, slightly laminated furniture, etc. That is to say, a little plastic is used. Many people naturally think: Can you use a good glue with less formaldehyde? The answer is no! You want to; Imported good glue is very expensive, and it is equipped with a microplate; The board looks hollow, and bark and environmental protection can't sell at a good price, so it must be good material mixed with glue to sell at a high price, and the slightly inferior board mixed with glue can be dumped at a low price. This will never be misplaced!
3. Composite floor
The mother board of composite floor is called "medium density board". In the process of processing, a large amount of formaldehyde mixed wood powder is needed to be molded at high temperature and high pressure. In addition, when the wear-resistant surface layer is laid, it must be fixed with super glue, so formaldehyde also diffuses in use. The higher the room temperature, the greater the formaldehyde diffusion.
4. wallpaper
Formaldehyde is used in the manufacturing process of pvc wallpaper and chemical fiber wallpaper. In order to make the wallpaper stick to the wall better, it should be stuck with glue, and a certain amount of formaldehyde will be slowly emitted into the indoor air.
Whether pregnant or alive and kicking, for health reasons, don't live in a house with excessive formaldehyde or other pollutants.
According to China's current standard (GB 18580-200 1), the maximum allowable indoor formaldehyde concentration is 0.08mg/m3.
Popularize science on the harm of formaldehyde exceeding the standard;
1. When the formaldehyde concentration reaches 0.08-0.09mg/m3, children will have mild asthma; 2. When the formaldehyde in indoor air reaches 0.2mg/m3, it will have peculiar smell and make people uncomfortable; 3. When the formaldehyde concentration reaches 0.5mg/m3, it may cause tears in eyes; 4. Formaldehyde reaches 0.6mg/m3, which may cause throat discomfort or pain; When the concentration is high, it can cause nausea, vomiting, cough, chest tightness, asthma and even pulmonary edema; 5. When the concentration of formaldehyde reaches 30mg/m3, people will die immediately.
The sources of formaldehyde in home decoration are adhesives and paints used in various materials.
The unqualified raw materials or processes of some inferior products will lead to excessive formaldehyde, which usually lies in the use of various panel furniture and paints. Don't blindly believe in the formaldehyde emission of a single furniture material. After all, you can't just leave your furniture at home, can you? You should learn to add and add.
So how do individuals remove formaldehyde in home improvement?
ventilate
Ventilation is the most effective method. In the experiment of the influence of ventilation on formaldehyde concentration, after three months of forced ventilation, the indoor formaldehyde concentration will drop from the initial 0.248mg/m3 to 0.07 1 mg/m3, a decrease of 75%.
Green plants and activated carbon
This is controversial, but some plants have good digestion ability for formaldehyde, so don't go to a treasure to search for formaldehyde adsorption. I suggest you really check some authoritative reports and make a choice.
Question 6: What kinds of common decoration pollution are there? Where do these pollutions come from? I don't know the professional answer, but my work is related to this, so I know more or less, hoping to help you.
Formaldehyde: glue can be formed without formaldehyde. As long as glue is used, formaldehyde may exist. The lower the cost, the higher the formaldehyde content, and the formaldehyde volatilization cycle is as long as 3- 15 years, which is difficult to remove without professional cleaning. (The formaldehyde content stipulated by the state is lower than 0. 1mg/m3)
Benzene: mainly paint decoration, paint and wood paint; There will be a special introduction on Baidu, and many articles are also about this;
Radioactive elements: mainly in tiles; This is what I just learned. There is a special entry in the encyclopedia called "tile radiation";
Ammonia: this is more common in concrete, and brightener additives are coated on furniture, all of which contain ammonia water;
That's all I know. Many harmful substances cannot be eliminated by themselves. If there are pregnant women, children and the elderly at home, it is best to ask a professional company to test the newly renovated house.
The most important thing: be sure to ventilate more!
Question 7: What are the main indoor decoration pollution gases: formaldehyde, triphenyl, ammonia, radon and TVOC?
There are three standards for formaldehyde in indoor air quality (0. 10, 0.08, 0. 12 mg/m3).
Indoor air quality testing measures whether a house meets the sanitary requirements of the living environment, according to GB/T 18883-2002 indoor air quality standard.
Indoor environmental pollutants detection The environmental acceptance test of civil construction projects and interior decoration projects is based on the standard GB50325-200 1 Code for Environmental Pollutant Control of Civil Construction Projects.
GB/T 18883 Indoor air quality standard is formaldehyde 0.10 mg/m3;
Formaldehyde standard in GB50325 Code for Indoor Environmental Pollution Control of Civil Building Engineering
Class I building ≤ 0.08mg/m3
Class II buildings ≤ 0.12mg/m3;
A class of civil construction projects: residential buildings, hospitals, old buildings, kindergartens, school classrooms and other civil construction projects;
Class II civil construction projects: office buildings, shops, hotels, cultural and entertainment venues, bookstores, libraries, exhibition halls, gymnasiums, public transport waiting rooms, restaurants, barbershops and other civil construction projects.
Question 8: What are the decoration pollution? Some time ago, I planned to decorate it, so I studied it with my daughter-in-law on the panda non-toxic decoration online. Decoration pollution, mainly formaldehyde, benzene, ammonia.
Question 9: What is the main pollution source of new house decoration? 1, chemical glue, such as putty glue, putty rubber powder, interface glue, waterproof glue, structural glue, woodworking glue, etc.
2. Plate: used for ceiling, partition, etc.
Reasons for containing formaldehyde: Glue is used in plate production, so the plate contains formaldehyde.
National standard plate size:1.22m 2.44m.
(1.22m 2.44m, about 45px thick, glue about 3kg)
3. Wood flooring
Solid wood flooring: cheap, convenient, with more glue and strong toxicity.
Solid wood composite floor: the price is average, the amount of glue used is average, and it is toxic.
4. Wood coatings
Waterborne paint: environmental protection, basically non-toxic, good water solubility.
Oily paint: It is toxic and harmful to melt with Tianna water.
5, latex paint
Waterborne latex paint, firm structure, moisture-proof.
Film-forming latex paint is mainly used as raw materials of styrene-acrylic and benzene series. Toxic, with benzene poison.
6. wallpaper
Use mucilage to make wallpaper, and the national environmental protection standard of wallpaper should not exceed 120mg per kilogram.
7. Wooden door
1, high-density paint door: bad paint, toxic; The base material contains glue, which is toxic.
2. Wood-based panel composite door: toxic substances come from plates and paint.
3, solid wood door: refers to the solid wood door (environmental protection, less glue), the substrate is no problem, look at the paint, water-based environmental protection paint can be non-toxic.
4, the original wooden door: the base material is non-toxic, look at the paint, and the environmental protection paint is non-toxic.
8. Equipment
1, furniture painted on high-density board and particleboard is toxic. Toxic substances come from materials and paints.
2. Furniture made of painted wood-based panels is toxic. Toxic substances come from materials and paints.
3, log furniture, environmental protection and non-toxic.
9, cabinets
The countertop is made of artificial stone, which is non-toxic and harmless, mainly from the plates of the ground cabinet and the hanging cabinet.
Question 10: What are the five main culprits of indoor decoration pollution-mainly from plates, such as wood-based panels, sandwich panels and adhesives? Long-term contact can cause cancer of nasal cavity, oral cavity, nasopharynx, throat, skin and digestive tract; Low-dose exposure can lead to chronic respiratory diseases, pregnancy syndrome and even nasopharyngeal carcinoma.
Benzene mainly comes from paints, coatings, adhesives, wallpapers, carpets, synthetic fibers, detergents and solvents. Benzene has a special smell, but it is a strong carcinogen. Long-term inhalation will destroy the human circulatory system and hematopoietic function, leading to leukemia.
Radon-The latest research released by the World Health Organization shows that radon has become the second leading cause of lung cancer after smoking. Professor Zhi, director of the lung cancer diagnosis and treatment center of Capital Medical University, said that radon is a natural radioactive gas, colorless and tasteless, just like "invisible smoke". Its main hiding places are granite and ceramic products such as tiles and sanitary ware. The average radon content per cubic meter increased 100 baker, and the risk of lung cancer increased 16%. In the United States, about 60 people die of radon every day, which exceeds the number of AIDS deaths.
Ammonia-mainly comes from concrete additives and interior decoration materials. Ammonia gas is very soluble in water, and has a rapid effect on eyes, throat and upper respiratory tract, and is strong in * * *. Tears, sore throat, cough, chest tightness, dyspnea, dizziness, vomiting, fatigue, etc. It will appear after inhaling a large amount of ammonia for a short time. Especially in winter construction, it exists in antifreeze in large quantities.
Total volatile organic compounds-mainly from furniture, wallpaper, etc. It can cause immune level disorder, affect the function of central nervous system, appear dizziness, headache, lethargy, chest tightness and other symptoms, and may also affect the digestive system, leading to loss of appetite, nausea and so on. In severe cases, it will damage the liver and hematopoietic system.
