Wallpaper has a broad market in recent years, but environmental protection has become the first factor that people should consider when choosing wallpaper. Many people have doubts about the environmental performance of wallpaper. Is wallpaper poisonous? Does the wallpaper have formaldehyde? Does the wallpaper taste? Is wallpaper harmful to people? Does the wallpaper have formaldehyde? People are worried about a series of problems, especially PVC wallpaper. Some consumers think that PVC wallpaper contains heavy metals. In fact, the wallpaper itself is not polluted, and environmental protection depends on the original paper itself.
1. Heavy metals come from printing pigments. Waterborne or oily refers to different solvents used for pigment dilution. Water-based pigments use water as diluent, which volatilizes in the production process and has no influence on the factory environment. Ethyl acetate is used as a diluent for oily pigments, which will volatilize in the production process. If it is directly vented, it will pollute the air and environment above the factory, and most factories use recovery devices for treatment. Therefore, whether the printing ink is environmentally friendly does not depend on the water-based oil-repellent diluent, but on the pigment itself.
2, formaldehyde, from wallpaper base paper. Whether wallpaper is environmentally friendly depends on the base paper itself. At present, many enterprises use imported base paper or natural plant fiber as base paper, which is basically pollution-free.
3. Monomer vinyl chloride comes from the coating material pvc of wallpaper. Pvc is a high molecular polymer. Under normal environmental conditions, the chlorine contained in it will not cause even the slightest harm to people. Only when there is a fire at high temperature will chlorine be decomposed and released. If the content exceeds the standard, people will suffocate and cannot escape.
Is there any pollution in the bedroom decoration wallpaper?
Many people like to put up wallpaper when decorating their bedrooms, but they don't know? Also, how to remove harmful gases in the bedroom? There are many colorful and varied wallpapers on the market. Maybe someone wants to stick these wallpapers on the bedroom wall, but when they buy them back, they are a little scared and don't know? Everyone may have their own opinions, and some people think that these smells will dissipate by themselves after a period of time. Is this view correct? Ms. Lin has always dreamed of having a beautiful bedroom. At the end of the bedroom decoration, Ms. Lin took a fancy to a pink wallpaper in the building materials market. She really wanted to buy it at once, but she was worried? Seeing Ms. Lin's worry, the shopkeeper told Ms. Lin that this smell could be emitted over time. Ms. Lin thought for a long time and bought this wallpaper for her dream bedroom. Who knows, the smell of wallpaper has not been released for more than two months. Because of this, Ms. Lin regrets her decision. It should be said that Ms. Lin really doesn't know enough about wallpaper. Strictly speaking, the smell emitted by wallpaper may not be emitted indoors for more than half a year. At the same time, during this time, the human body will still inhale more polluting gases such as formaldehyde. It can be said that people are lucky to stay in such an environment without getting sick, and it is irrational to continue living. Even if they want to live, they must take measures to clean up the pollution in the bedroom. Then, if Ms. Lin opens the doors and windows, can she clean up the pollution within one month? I don't think this is enough. Ms. Lin had better buy activated carbon and put it in a place with strong smell in the bedroom, because activated carbon can really play a certain adsorption role. At the same time, you need to buy a few pots of Euonymus japonicus or aloe vera to put in the bedroom, but you can't put too many plants, because too many plants will absorb too much oxygen indoors and release too much carbon dioxide, which is harmful to human health. Secondly, Ms. Lin can also put a few pots of water under the bed or other places, because water also has a certain absorption effect on odor. In addition, some friends have used the method of removing the smell of onions, mainly by chopping some onions with a knife and soaking them in vinegar, and then putting several bowls in a room with a strong smell. A situation like Ms. Lin can also be tried. What's more, put the pineapple directly in the room to remove the odor. This method should also have an impact on the smell of wallpaper. In short, if someone doesn't understand, they can try it themselves. But according to the survey, most people will face the problem of pollution after pasting wallpaper. Although the above methods may solve the problem, consumers should smell it with their noses when buying wallpaper, and try to buy wallpaper with less pollution.
How about wallpaper for wall decoration?
From the perspective of environmental protection, compared with other interior decoration materials, wallpaper has the lowest side effects on human health. However, wallpaper is wallpaper, a raw material and a single product. Don't forget, wallpaper is paved with varnish and wallpaper glue, and then wallpaper is paved. At this time, the shape of wallpaper has changed a lot. After the wallpaper is pasted, the wallpaper glue is covered inside, and formaldehyde is difficult to volatilize, so the release cycle of formaldehyde is much longer than that of wall paint.
Wall paint also contains formaldehyde, but the construction process is less than wallpaper. Comparatively speaking, after normal latex paint is painted, it almost evaporates in three days, and it has no taste in 15 days. But there is another pollution in wall paint, that is, mercury and lead. After the wall is painted, it is easy for children to touch it with their hands, and some children will habitually suck their fingers, so that mercury and lead in the paint will have an impact on their bodies. Developed countries such as Europe and America also used paint as the first choice for interior decoration as early as the forties and fifties, but it is basically not used now.
As can be seen from the above comparison, both wallpaper and wall paint have their own environmental protection problems. So, on the one hand, I don't suggest you spread wallpaper everywhere; On the other hand, we also have a good reason to choose wallpaper. After all, the effect created by wallpaper can't be achieved by wall paint.
1, to buy wallpaper, you must first understand the types of wallpaper, and the performance of different wallpapers varies greatly. There are many kinds of wallpaper on the surface, but there are two common ones, pure paper wallpaper and plastic wallpaper (as well as fabric wallpaper, natural material wallpaper, metal wallpaper and other varieties). Pure paper wallpaper: pulp material, environmental protection and ventilation. However, the water resistance and scrubbing resistance are poor, and the construction is inconvenient. Now the water resistance and scrub resistance of some imported papers have been greatly improved, but they still can't be compared with PVC wallpaper. Plastic wallpaper, namely PVC wallpaper, can be divided into ordinary PVC wallpaper and foamed PVC wallpaper. The advantage of PVC wallpaper is scrub resistance, and it can also be made into a larger three-dimensional shape (foamed PVC wallpaper), which is relatively strong and convenient to construct, but its air permeability is not good, and its biggest disadvantage is pollution, especially foamed PVC wallpaper. So the choice of wallpaper depends on the use environment. All-paper wallpaper should be selected for horizontal full paving, and some PVC wallpaper with good quality can also be used in other places such as living room if the amount is not large.
2. Which is better, wallpaper or latex paint? There is a great debate. Let me talk about my own opinion: from the price point of view, wallpaper is definitely expensive. A square meter of cheaper wallpaper is about 30-40 yuan, and the best price latex paint is enough. From the perspective of environmental protection, the pollution of PVC wallpaper is relatively large, as soon as it smells; Pure paper wallpaper is better than latex paint, and good latex paint has little pollution. However, it should be noted that pure paper wallpaper is not absolutely pollution-free. When printing ink is used, heavy metal ions such as lead will inevitably remain. It is irresponsible to say that pure paper wallpaper is absolutely pollution-free. Pure paper wallpaper is the best in breathability; Latex paint is second; PVC wallpaper is the worst. PVC wallpaper is very good in water resistance and scrub resistance, and pure paper wallpaper and latex paint are all so-so. They can only be said to be "scrub-resistant", not as advertised by JS. Bump resistance, three bad, latex paint can make up, but the effect of making up is not good. I think the service life is similar. Latex paint will change color after long use, but it is not obvious. From the aesthetic point of view, wallpaper should occupy an absolute advantage, and latex paint is far behind.
3. The standard size of wallpaper is 52CMX 10M, but Japanese wallpaper is 92CMX5M. Japanese wallpaper can generally be cut and bought, but it is quite suitable if the amount is small. However, the style of Japanese wallpaper is simple and elegant, and warm colors are rarely used. There is a unique Korean wallpaper with a thick interface at one end; A thin end, a thick end when glued. The interface is obvious, we are not used to it, but Koreans think it is normal, so we should pay attention when buying it.
It is troublesome to calculate the amount of wallpaper. The general formula is: room circumference x wall height /5.2+ one roll = the number of rolls used, but it is generally not enough. The loss rate of wallpaper promoted by JS is 10%- 17%. From my experience, most cases are greater than this ratio. Because the loss rate of wallpaper is related to the wall height, wallpaper pattern size, wall complexity and cutting method, the wall height is the decisive factor. The loss rate of 10%- 17% is calculated according to the height of foreign houses, generally reaching 3 meters to 3.2 meters, and the wallpaper of 10 meter is just cut into three sections. Houses in China are generally 2.6 meters to 2.7 meters high, with three sections of surplus; Cutting off a quarter is not enough. I thought adding the top corner line and kicking ... >>
Will wallpaper be harmful to your health for a long time?
First of all, from the "absolute" aspect, wallpaper is environmentally friendly and not environmentally friendly. Whether it is environmental protection mainly depends on four indicators: paper base, material, ink and glue. First look at the paper base. Many paper bases in China are made by ordinary printing houses, so it is impossible to make home decoration pollution-free in terms of environmental performance. However, some high-grade paper and some imported paper bases can reach the pollution-free standard. For example, Taobao's Philippine space wallpaper is based on paper imported from Finland, so it can be pure natural and pollution-free. Second, look at the material: At present, there are three popular materials on the market, PVC, non-woven fabric and pure paper, and their environmental protection performance has increased in turn. Pure paper can be basically pollution-free, of course, as in the first point, paper must pass the customs; Third, look at the ink. At present, the wallpaper market is mixed. Many wallpaper manufacturers blindly pursue profits, reduce costs, and use environmentally-friendly and highly polluting inks, that is, print newspapers, while some high-end wallpaper manufacturers, such as Philippine Space Wallpapers, use water-based inks, and their wallpapers even meet German contact food safety standards; Fourth, glue is also very important. Many self-adhesive wallpapers seem to be low-cost and easier to construct, but the glue used is very environmentally unfriendly, and it is also very troublesome to peel off the wallpaper later. Using inferior glue, not to mention the environmental protection performance of wallpaper itself, the pollution brought by glue itself is enough for you. The glutinous rice glue I know is pure natural and can meet the environmental protection standards.
Secondly, of course, from the "relative" point of view, even the lowest PVC wallpaper is much better than latex paint and coating (also known as liquid wallpaper) in environmental protection performance, so the environmental protection performance of wallpaper is better.
I hope I can help you. Remember to adopt!

Is the wallpaper polluted?
As long as the quality of the wallpaper itself is up to standard, there is no sexual smell.
Relatively speaking, the environmental protection problem of wallpaper itself is not big. The main construction method is gluing (generally, sweet potato powder is more environmentally friendly now), so it is nothing to pay attention to environmental protection during construction. In short, the pollution of wallpaper is not great, provided that the wallpaper is qualified and the construction quality is high. I suggest you go to a regular store to buy it, and their construction team is also very quality.
Will wallpaper be polluted in the room?
It depends on the quality of the wallpaper you choose. Generally, it's nothing if you get better. Wallpapers are popular now. Try to buy good ones.
Will wallpaper pollute indoor air?
The pollution of wallpaper itself is not mainly caused by glue pollution, but also by volatile substances such as formaldehyde, but there is basically no pollution after a lot of ventilation.
Is wallpaper seriously polluted?
From the perspective of environmental protection, compared with other interior decoration materials, wallpaper has the lowest side effects on human health. However, wallpaper is wallpaper, a raw material and a single product. Don't forget, wallpaper is paved with varnish and wallpaper glue, and then wallpaper is paved.

After the wallpaper is pasted, the wallpaper glue is covered inside, and formaldehyde is difficult to volatilize, so the release cycle of formaldehyde is much longer than that of wall paint.
Is it polluted to decorate the walls of the house with wallpaper?
The wallpaper itself is not too polluted. The pollution comes from the wall putty surrounded by wallpaper glue and wallpaper. Wall putty contains a lot of glue, which is one of the sources of formaldehyde in decoration, but the wall paint or wallpaper is temporarily closed and can be released slowly in 2~3 years. Therefore, regular ventilation or the use of air purifiers to remove formaldehyde is a long-term process and must not be taken lightly!
