What is wallpaper?

Wallpaper is a special kind of paper used to decorate walls. 1 m wide roll paper with a basis weight exceeding150g/m2. It has certain strength, beautiful appearance and good water resistance. The surface is easy to clean. Does not contain harmful substances. According to the quality requirements of products, products are divided into many categories, such as coated wallpaper, covered wallpaper, embossed wallpaper and so on. Usually, bleached chemical wood pulp is used to produce base paper, and then it is treated by different processes, such as coating, printing, embossing or surface plastic coating, and finally it is cut and packaged before leaving the factory. Used for interior decoration of houses, offices and hotels.

Wallpaper, also known as wallpaper, is a specially processed paper used to decorate walls.

It originated in Europe, and now it is the most popular in the developed countries of northern Europe, with the highest environmental protection and quality.

Ok, followed by Southeast Asian countries, Japan and South Korea, the wallpaper penetration rate is as high as nearly 90%.

Compared with other building materials, it can be said that wallpaper has the least toxicity in production technology, technology and use. The main raw material of modern new wallpaper is pulp synthesized from bark and chemicals, which is very natural, so the product will not emit harmful components when used.

According to market research, most environmentally friendly and healthy wallpapers are imported brands. For example, products from Britain, Germany, Italy, Spain, Japan and South Korea have a market share of about 70% in Beijing. The product quality of some Sino-foreign joint ventures has also reached the standards set by the World Health Organization.

Like other decorative materials, wallpaper is constantly developing and changing with the development of world economy and culture. The use of wallpaper in different periods reflects the comprehensive factors of local economic development level, new material science and popular consumer psychology. As early as the Tang Dynasty in China, people painted on paper to decorate walls. /kloc-In the middle of the 8th century, Moliis, an Englishman, began to produce printed wallpaper on a large scale, which has a modern style. With the change of the times, the development of wallpaper has been developing with the development of world economy and culture, and has experienced the development and change process of paper, paper painting, foam paper, printing paper, embossed paper and special craft paper.

The original wallpaper was made by drawing and printing various patterns on paper. It has a certain decorative effect, but it is only used for local decoration in high-level places such as the royal court. The real large-scale decoration materials entered home life in the late 1970s and 1980s.

Throughout the 1980s, foam wallpaper was very popular, and "foaming" was also called screen relief foaming. It refers to adding foaming agent to raw materials, supplemented by high temperature in the production process, so that the foaming agent can complete a process similar to "fermentation". Therefore, the wallpaper produced will have a concave-convex feeling and a soft touch. The advantage of this wallpaper is its strong three-dimensional sense, which can increase the sense of space in the room. But the disadvantages are also obvious: not wear-resistant, easy to scratch, easy to be polluted. At present, foam wallpaper has been gradually eliminated, but it can still be seen on the ceiling of some rooms.

By the end of 1980s, with the development of plastic industry, there appeared a substitute for foam wallpaper-gummed wallpaper. This wallpaper does not foam, so the texture is hard, which greatly improves the shortcomings of foamed wallpaper. Waterproof, moisture-proof, durable, beautifully printed and embossed, it can display all kinds of patterns and patterns on wallpaper at will, and its color expression and practicality have created a brand-new page in the development of wallpaper. At present, the utilization rate of adhesive wallpaper in the world accounts for about 70%.

At the beginning of rubber wallpaper, mercerized wallpaper with glossy texture was very popular. Later, with the change of fashion trend in home improvement industry, matte wallpaper (fabric wallpaper) gradually led the trend. Wallpaper is more and more expressive of colors and patterns, which is widely welcomed by consumers. Major manufacturers have launched fierce competition for this.

From the late 1990s to the early 20th century, wallpaper with a sense of fabric became popular. Since 2002, with the increasing demand for leisure, comfort and environmental protection, green and natural products will be accepted, and consumers' demand for paper wallpaper will further increase.

At present, the penetration rate of wallpaper in Japan and Russia is close to 100%, and it is also 50%-65% in Europe and America. The current permeability of China is less than 1%! With the development of China's economy and the continuous improvement of people's living standards, I believe that wallpaper, as a necessity, will definitely fly into the homes of ordinary people!

As a decorative material that can beautify the environment, wallpaper is suitable for many places, such as:

Household paper: living room, bedroom, dining room, children's room, study room, recreation room, etc.

Commercial space: hotels, restaurants, department stores, shopping malls, exhibition venues, etc.

Administrative space: office buildings, government agencies, schools, hospitals, etc.

Entertainment space: restaurants, dance halls, bars, KTV, nightclubs, teahouses, cafes, etc.

Wallpapers are divided into hand-made wallpaper, PVC plastic wallpaper, cloth-based PVC wallpaper, pure paper wallpaper, paper wallpaper, non-woven wallpaper, diatomite wallpaper, luminous light storage wallpaper, wood fiber wallpaper, glass fiber wallpaper, natural material wallpaper, metal wallpaper, gold and silver foil wallpaper, fabric wallpaper and so on.

Edit this paragraph to select an idea.

The wallpaper is like a dress on the wall at home, which makes the whole home full of lively expressions. Especially for personalized and high-quality decoration, the new wallpaper has the effect that interior wall coatings can't achieve in terms of texture, decorative effect and practicality. According to the prediction of foreign experts, wallpaper will still be the main material for interior decoration in the next 20 to 50 years.

Edit this paragraph function selection

A) Living room: In general, the living room is the main activity space of the owner, and bright and generous colors should be chosen, and the material should be high-grade wallpaper. First consider environmental protection and ventilation; The second option: the one with strong tensile and scrubbing resistance is better.

B) Bedroom: generally choose warm colors or wallpaper with small flowers or patterns to create a warm and comfortable feeling.

C) Second bedroom: If the elderly mainly live in it, they should choose some colorful wallpapers that can make people quiet and calm, or they can choose some plain flower wallpapers according to the preferences of the elderly.

D) Children's room wallpaper: generally choose wallpaper with bright colors and decorated with cartoon waist lines, or use wallpaper with cartoon patterns on the upper part and plain stripes or plain colors on the lower part to create a pleasant and tidy effect.

Edit this paragraph color match.

A) Overall color matching: choose wallpaper with the same color and post different patterns in different rooms.

B) Functional distinction and collocation: Choose different color collocation according to different positions.

C) General collocation attention: the color system should be uniform, and it is not easy to use wallpaper with large contrast and cold and warm colors in the living environment. Compatible colors can convey the overall aesthetic feeling, while bright contrast will make the space lively and changeable. Natural harmony and seamless integration are the highest realm of wallpaper decoration. If a guest praises "your wallpaper is really beautiful", be careful. Because wallpaper contains vivid features such as color, pattern and texture, it should not stand out too much. After all, it's just background. The sentence "Your wallpaper is really beautiful" may just indicate that the wallpaper is out of harmony with the environment. Therefore, the overall unified design is particularly important. When deciding the style of wallpaper, we should consider the synchronous design of floor materials, furniture, decorations and lighting. In addition to special effects such as size, generally speaking, the purer the wallpaper color, the more elegant the pattern, the more lasting and classic the paving effect, so as not to cause visual fatigue.

Edit this paragraph mode selection

A) The vertical stripe pattern increases the height of the room.

Long pattern wallpaper has many characteristics such as permanence, classicality, modernity and tradition, and it is one of the most successful choices. The long strip design can spread the color on the whole wall in the most effective way, and it is simple and generous, which is very easy to match with other patterns. There are many designs of this pattern, including length, width and size, so you must choose a pattern that suits the size of your room. This is quite important. A slightly wider strip pattern is suitable for a smooth large space, while a narrower pattern is more suitable for a small room.

Because the long pattern design has the effect of guiding the line of sight upwards, it will create an illusion about the height of the room, which is very suitable for short rooms. If your room is already very high, it will be good to choose a wide strip pattern, because it can extend the line of sight to the left and right.

B) The large flower pattern reduces the sense of restraint in the room.

In the wallpaper exhibition hall, bright patterns and flowers are the most eye-catching. Some flowers have vivid patterns and strong colors, which really make you feel like you are coming from a distance. It is reported that this kind of wallpaper can reduce the bondage of the room and is suitable for rooms with relatively plain patterns. Because most of these patterns are exaggerated, they should be matched with European classical furniture. People who like modern minimalist furniture had better not choose this wallpaper.

C) Small and regular patterns add a sense of order to the room.

Conventional wallpaper with small patterns can provide a background that is neither exaggerated nor too dull, and your favorite furniture will fully display its characteristics in front of this background. If you choose wallpaper for the first time, it is safest to choose this wallpaper.

When choosing wallpaper, we should consider the area, spatial scale and orientation of the room. In principle, wallpaper is suitable for posting in any room, and suitable wallpaper can be found from living room to bedroom to kitchen. Secondly, the advantage of wallpaper is that it is easy to distinguish which room is a bedroom and which is a children's room by decorating the room with different wallpaper.

The living area of most families is not spacious, so according to people's psychology of wanting a comfortable environment, it is best not to choose wallpaper with too eye-catching textures and patterns, and the proportion of patterns should be appropriate. If the graphic pattern is too large, it will cause a sense of "proximity" visually. From the color point of view, the room facing north should not use cool colors such as blue and purple, but should use warm wallpaper of yellow, red or brown to avoid feeling too cold in winter. The room in Chaoyang can use cold gray wallpaper, but it is not suitable for sky blue and lake blue, which are uncomfortable in winter.

The living room should choose fresh and elegant wallpaper; The restaurant should use orange wallpaper; The bedroom can be freely played according to personal preferences: red wallpaper can create an exciting atmosphere, while cool wallpaper such as blue and blue is conducive to relaxing, while yellow wallpaper is the best choice to create warmth and romance.

The characteristics and advantages of editing this paragraph

1, there are many kinds and colors of wallpaper, which have a strong decorative effect.

A) Strong decorative effect: There are many kinds of colors and patterns of wallpaper, and there is a large choice. The decorative effect is rich and colorful, which can make the home more warm and harmonious. After improving the pigment formula, the current wallpaper has solved the fading problem.

B) Wide application range: the base material is cement and wood, which can be used in plastering the wall, and it is easy to keep in harmony with the color and style of interior decoration.

C) Convenient maintenance: high-quality wallpaper has the advantages of anti-static function and no dust collection. If it is accidentally or artificially contaminated, it can be cleaned with clean water and a small amount of detergent, which is easy to clean and has good renewal performance.

D) Safe use: The wallpaper has certain sound absorption, heat insulation, mildew and bacteria prevention functions, good anti-aging and insect prevention functions, and is non-toxic and pollution-free.

E) Wallpapers have a strong decorative effect, and different styles of wallpapers can often create personalized spaces with different feelings. Whether it is simple style or rural style, rural style or Chinese, western, classical and modern, wallpaper can outline a new feeling, which latex paint or other wall materials can't do.

2, wallpaper paving time is short, which can greatly shorten the construction period.

3. The wallpaper has the characteristics of relatively good wear resistance, pollution resistance and easy cleaning.

4. The wallpaper has anti-crack function. When making latex paint on insulation board, whether it is dacron cloth or bandage, some cracks will be exposed shortly after completion, and wallpaper can avoid this defect well. As long as the pavement is in place, small cracks will not appear again. Of course, if the thermal insulation wall has great quality problems in real estate, no matter what decoration, it may crack in a big mess.

One advantage of wallpaper different from other interior decoration materials is that it is very convenient for daily use and maintenance, washable and erasable, and has no other special requirements. Care should be taken to keep the indoor environment dry during maintenance.

Edit this paragraph to determine the quality.

Generally, it should be identified from the following aspects:

1. First, judge whether the material is natural or synthetic (PVC). The simple method can be judged by combustion. Generally, natural materials have no peculiar smell and black smoke when burning, and the dust after burning is powdery white ash, while synthetic (PVC) materials have peculiar smell and black smoke when burning, and the ash after burning is black spherical.

2, water scrubbing: good wallpaper color fastness can be scrubbed and maintained with a wet cloth.

3. Green is harmless. When buying, you might as well smell the product up close to see if it smells. Odor products may contain excessive toluene, ethylbenzene and other harmful substances, which can cause cancer.

4, the color is long. The surface coating materials and printing pigments of wallpaper need to be optimized and strictly controlled to ensure that wallpaper (especially light-colored and white wallpaper) will not yellow after long-term illumination.

5. See if the pattern style is unique and the production process is excellent.

Edit this paragraph maintenance and maintenance

Someone asked: Is the wall covering life of wallpaper or the decoration time of latex paint plain wall long? This question is not easy to answer on the whole. Conventionally, the service life of wallpaper wall covering is of course long, because the plain surface of latex paint is easy to get dirty, and the scrubbing process can't have no influence on the wall surface. Generally, the service life of this wallpaper is about 5- 10 years. However, wallpaper wall covering is not. It can well maintain 10- 15 years. Therefore, the maintenance of wallpaper and wall covering is the key.

Matters needing attention in wallpaper maintenance

1) During the construction period, the relative humidity of the air should be lower than 85% and the temperature should not change drastically, so it is necessary to avoid construction in wet seasons and wet walls.

2) During the construction period, doors and windows should be opened to keep ventilation during the day; Close the doors and windows at night to prevent moisture from entering. The wallpaper just pasted on the wall is forbidden to be blown by strong wind, which will affect its adhesion and surface engineering.

3) When pasting wallpaper wall covering, the spilled glue should be wiped clean with a clean towel at any time, especially the glue marks at the joints. This is something that constructors or supervisors must carefully check. Construction personnel should keep their hands and tools highly clean. If there is any stain, it should be cleaned with soapy water or detergent in time.

4) Foamed wallpaper wall covering is easy to accumulate dust, which affects its neat appearance. It should be cleaned every 3-6 months. Scrub with a vacuum cleaner or brush dipped in clean water, and be careful not to let water penetrate into the joints.

5) Don't use the pasted wallpaper, and pay attention to prevent scratches from hard objects or sharp objects. After a certain period of time, in some places, the cracks at the joints should be subsidized in time and not allowed to develop.

6) When water droplets and steam hang on the wall of bathroom wallpaper, please open the window and exhaust fan in time, or wipe the water droplets with a dry towel first, because the quality of wallpaper will be damaged and white spots or bubbles will appear after long-term use;

7) If the room is too dry, open the window in time to avoid direct sunlight for too long, otherwise it will have a great negative impact on the color of dark wallpaper.

Error in wallpaper application when editing this paragraph.

1, think wallpaper is toxic and harmful to human body. This is a wrong propaganda orientation. From the production technology, process and use of wallpaper, PVC resin does not contain harmful components such as lead and benzene. Compared with other chemical building materials, wallpaper can be said to be non-toxic. From the application point of view, the usage of wallpaper in developed countries far exceeds that in China. Technology and application show that plastic wallpaper is harmless to human body.

I think the use time of wallpaper is very short. Unwilling to change frequently and afraid of trouble is an outdated and backward concept. The biggest feature of wallpaper is that it can be updated at any time. It often changes the atmosphere of living space, which is often fresh. If you can change the room atmosphere once a year without spending too much money and time, it is undoubtedly a good mental adjustment and enjoyment. Some families in developed countries change once a year, and some change twice a year. We should change the wallpaper at home for Christmas and birthday.

3, think that wallpaper is easy to fall off. It is not the wallpaper itself that is easy to fall off, but the pasting process and the quality of glue. Using wallpaper is not only harmless, but also has three advantages: first, it is easy to update; Second, it is easy to paste; The third is strong selectivity. At present, the wallpaper on the market has different prices because of the different cost and production technology, some are very cheap, and some will be very expensive.

Frequently asked questions about editing this paragraph

Powder wall: that is, there is unstable powder on the wall, which should be polished off, leveled, coated with varnish or wallpaper basement membrane with high environmental protection performance, and wallpaper can be pasted after it is completely dried.

Smooth wall: the wall is very smooth, so it is not easy to absorb glue and dry, and then the strength will drop, so it needs sandpaper to paste wallpaper.

Repair putty: add more white mucilage to the putty to make it firm and not crack.

Scraping putty: add a small amount of white mucilage to the putty for polishing.

Adding white mortar to gypsum powder instead of leveling putty can speed up drying and shorten construction time.

Treatment of wet walls: the living room walls are wet or even moldy. At this time, the wall surface can be coated with anti-seepage liquid to form a colorless and transparent waterproof film layer, which can not only prevent the infiltration of external moisture, but also keep the wall surface dry, and then decorate it. If the wall is already wet, let the wet wall have a drying process for one to two months, and then brush a layer of waterproof slurry mixed with cement on the wall to prevent it from being wet. Secondly, fill the pits on the wall with gypsum putty, and polish the wall with sandpaper after drying. Next, the primer can be coated twice with a coating roller or sprayed on a dry and clean wall.
