Resistance to chemicals such as strong performance. Although the color dye is easy, but easy to hydrolysis, in the wet loss, pollution and strong, into the paper, color fastness is poor, without acid, alkali and other chemicals. If you use nano-pigments, colored paper can solve the problem of color fastness. Recent studies have found that the nano-titanium dioxide, chrome yellow, red iron oxide powder added to the chemical fiber, etc., you can cover the excessive ultraviolet radiation. Use of computer simulation of the design found in the titanium dioxide particle size 50-120nm, the absorption of ultraviolet rays the best. This shielded the powder particle size range by adding fibers, can be made into the high light of the matte white and colored paper, colorful,ed hardy clothing, and the effect of UV can be achieved. Inorganic inorganic fiber paper, processed into nano-inorganic fiber has good dimensional stability, heat resistance, chemical resistance, flame resistance and electrical insulation. These properties are beyond the reach of plant fiber. The representative of the inorganic fiber - glass fiber can not withstand the beating because of, the lack of bonding between the glass fiber, paper copy into a page is very fragile. However, if control of the 100nm diameter glass below the glass stretching can solve the small, soft as a result of poor paper hard problem, is conducive to forming fibers intertwined. Flavoring nano color paper will be used in nano-technology development of flavored paper, flavored paper will make quality, printability and so greatly improved, high-end print images printed will be more delicate, lifelike. The color of paper used in printed publications flavored, primary and secondary school textbooks, exercise books, notebooks and other children's books, people will not read the white paper, high and eye irritation, eye and thus reduce the time to read Department of fatigue, protect eyesight and prevent myopia have a certain effect. Therefore, this one flavored paper launch, by the majority of users. Nano is the ability to stop the fire retardant paper burning paper. It is, no matter how much firepower, will not cause a fire, and only charred, carbonized. This kind of paper use,air jordan shoes cheap, waste paper can be treated without any degradation in the natural release of harmful substances. Flame-retardant paper generally used for fireworks, fireworks, firecrackers, Christmas toys, travel cookers, is the festive supplies (a variety of festive scenes, and create a cheerful atmosphere, interior, etc.) in an ideal green environmental protection product. Some people even suggested in this paper made of firefighters and other people often have to deal with the fire, clothes, clothes to prevent burning, fire played a role. In addition,ugg milano, flame-retardant paper used in dry-type transformer, a safe, non-toxic, flame retardant and anti-radiation and so on. Paper, magnetic paper magnetic tape can be like that on the answering machine recording, the sound can also be run. Manufacture of magnetic paper is the paper added with magnetic material within the powder, or a magnetic material attached to the paper surface powder. This paper has been washed after the magnetic flux l students. With this paper itself has a magnetic, it can be directly attached to the iron object. Magnetic nano-technology in the paper, so that more good quality paper, the magnetic effect of better and more lasting. Source: China Paper Net United States to develop a better fuel cell performance of nano-Pd catalyst the United States Brown University chemists announced the development of better fuel cell performance of palladium (Pd) catalyst, the active surface area of palladium particles than conventional to about 40%,ugg prezzo, and nanoparticles intact 4 times the length. The results have been published in the Journal of the American Chemical Society (JournaloftheAmericanChemicalSociety) _k. Palladium has been used as a fuel cell research alternatives to platinum, palladium source and the price is much lower than the rich. However,air jordans, researchers with the difficulty of creating sufficient active surface area, fuel cells can achieve efficient palladium catalyst nanoparticles, and to prevent the fuel source into electricity, National Cheng Kung University particles gathered chemical process. Brown University researchers were able to find ways to overcome these challenges. This approach is quite novel. It has 2 times more active, which means only half of the energy for catalysis, but also the stability of 4 times. Palladium nanoparticles created size 4.5nm, the nanoparticles can be directly used as formic acid (CH: 02) in the carbon fuel cell platform.
