Cardboard furniture production has been industrialized by experts

"Paper paste" is often used to describe items that are not strong, but now "paper" has also become a material for making furniture. Cardboard furniture production has been industrialized and is available on the market. However, because it is a "plate," it is quite limited in its shape. Northeast Forestry University School of Material Science and Technology is engaged in pulp and paper technology research and development, so that paper can be freely "concave", not bound by edges and corners. On the 7th, Wan Hui, an associate professor at the college, explained this technique.
No one sitting on the paper stool deformation <br> into Wan Hui's office, the reporter was disappointed to find that the interior is an iron filing cabinet and wooden office chair.
A gray rectangular box was placed on a desk. When the reporter saw it, he was still whispered. What was the thickness of a gray brick on the desk? At this time, Wan Hui picked up the "gray brick" and said, "This is The stool made of pulp, made from waste newspapers, is not white because there is no deinking in the process."
The reporter took over and handcuffed, and found that the "gray brick" that looked thick was actually very light; the surface was rough, but it was warm to the touch and it was not as cool as a plastic stool. The lower part of the "gray brick" has a small base that is slightly narrower than the upper one. The reporter invited a graduate student at the scene to sit and test. Graduate student weighing 130 pounds, sat on this square small paper bench, a small paper bench firmly "stands" on the ground, without any deformation.
Wan Hui has been engaged in the research of pulp furniture for more than two years, and has conducted pulp molding children's furniture molding experiments. In an experiment conducted in 2012, the cylindrical solid stool was 30 cm high, 18 cm in diameter, and weighed about a pound. There was a round hole in the upper surface for easy lifting. She asked an adult with a weight of 240 pounds to sit on it and twist and move freely. The stool was completely free of distortion.
According to scientific measurements, a pulp board with a thickness of 15 mm can withstand a pressure of 500 newtons per kilogram without being damaged by adhesives or pressing. 500 Newtons is equivalent to about 100 pounds. If adhesives are added and they are pressed, the weight they bear will increase significantly.
After a night of rain pulp furniture is in good condition <br> Pulp furniture is made of paper fiber, mainly from two kinds of waste: one is waste paper, the other is wheat straw. Turning these two wastes into pulp furniture can be easily divided into five steps: the material is hand-picked, placed in a pulper for fiber separation, molded, dried, and finally trimmed.
If you want to make it more weight-bearing, you can add some auxiliaries, such as reinforcing agents, sizing agents, etc. before molding. Its drying method can be divided into natural drying, hot air drying, far-infrared radiation drying, microwave heating and drying.
Wan Hui said that if waste newspapers are used as raw materials, ink removal and decontamination procedures should be added to the production process; if wheat straws are used as materials, there is no need to worry about pollution, and the finished products are white, greener and greener, and suitable for children's furniture.
When the pulp furniture meets water, can it maintain its shape? When this question is heard, Wan teacher laughs and tells an unexpected experiment.
Wan Hui used a waste newspaper to make a solid pulp stool, but instead of putting it into a professional drying appliance, he put it on a balcony on the third floor of the college to let it dry naturally. Unexpectedly, it rained overnight. The next day I went to work, Teacher Wan looked at the stool on the balcony and the surface was wet, but there was no change in the hand. She then put the stool on the balcony and continued to dry naturally. After the air dried, the shape of the stool remained the same. The only change was that the upward side was stained with rain and yellowed.
In the office, the reporter also saw this experimental product. "I didn't do any waterproofing on the surface, but there was no problem with the surface being waterproof for a short time." Wan Hui said.
Pulp furniture is easier to "concave"
Paper furniture is environmentally friendly and can be recycled. According to related statistics, 1 ton of waste paper can be processed to regenerate 800 kilograms of new paper, 830 kilograms of paperboard, which is equivalent to saving 4 cubic meters of wood, which is equivalent to cutting down 17 large trees and saving 400 kilograms. The soda ash can save 400 kilograms of standard coal, save 500 kilowatt hours of electricity, and even more impressively, reduce the use of 4,700 tons of water. At the same time, it also reduces the emissions of about 1,000 kilograms of production waste and 35% of water pollution.
At present, paper furniture is divided into two categories: one is cardboard furniture, and the other is pulp furniture.
Cardboard furniture is mainly made of corrugated paper, which resembles large-scale home appliance outer packaging cartons, and is laminated to form the design force standards. It has now achieved industrial production and is entering the homes of the people subconsciously, especially among young people. The reporter saw on Taobao that the cardboard furniture had been sold and the price was much cheaper than wood furniture. However, due to the limitation of "plates," the shape is basically angular.
Pulp furniture is still in the research stage and there are no fully formed market products. Its advantage is that it is not limited in its shape. It can produce arcs, arches, and so on. It is more flexible in shaping. Wan Hui said that furniture products have been given a new concept, design and seek to transform and breakthrough will be the mainstream of furniture consumption in the future. People use furniture to meet the practical needs of the premise, can have the pursuit of fashion, assertive personality.
The main material of pulp molded furniture is paper fiber. It can make changes in style, get rid of the traditional furniture concept and form, do not use conventional adhesives, paints and other furniture auxiliary materials, with a light, stylish, safe, non-polluting fast features. In the design of the design, due to the rich variety of paper materials, it is possible to obtain both retro and modern styles; in terms of material texture, such furniture combines the texture of wood, rattan and textiles, elegant and solemn and breathable good. If it is children's furniture, you can also let children draw on paper furniture and become unique furniture. However, the problem of pulp furniture mold is still an urgent problem to be solved in scientific research.
