In industrial production, the car and even in daily life, will produce large amounts of carbon dioxide. According to incomplete statistics, there are billions of tons of carbon dioxide gas into the atmosphere every year. There is no doubt that the carbon dioxide will cause bad influence to the earth's environment. As the "principal" greenhouse effect, the planet of carbon dioxide in recent years, the image is not welcome.
However, carbon dioxide will only cause trouble really? Don't forget to carbonated drinks, foam fire extinguisher and cool "artifact" dry ice, more don't forget to plant growth is crucial in the process of photosynthesis. Plants in the sun, the use of photosynthetic pigment, convert carbon dioxide and water into oxygen and carbohydrate - the former provides the foundation to the survival of biology, the latter directly provides power source for plant growth and "building materials".
Carbon is one of the important elements in the chemical industry, a large number of chemical products mainly of carbon. So, will you please, like plants, co2 as carbon source, produce the plasticizing "building materials"? In 1969, a Japanese scientists first proposed the idea of co2 as a "dream" raw material - to turn carbon dioxide into carbon dioxide based polymers, used to make plastics. Called it a "dream" raw materials, not only because of carbon dioxide, low cost and abundant reserves, but also because it can greatly reduce the dependence on oil and other fossil raw materials in plastic industry, thus expanding the scope of the basic chemical raw materials, open up a new way to sustainable development.
However, the last part at combustion chain of carbon dioxide, its chemical properties are very stable, it is hard to decompose under general conditions. Combined with their own, and so must be under the impetus of the high-performance catalyst, can realize the transformation of carbon dioxide. More than 40 years, looking for the right catalyst has always been a difficulty.
Not long ago, the German advanced polymers and high-performance plastics manufacturers strong company announced that success find out super catalyst, can convert carbon dioxide into carbon source for industrial production, the world's first use of carbon dioxide in the production of foam plastic factory in Germany also Thomas root formally put into production. Think a chief executive Patrick Thomas said, in the process of production, carbon dioxide up to 20% of raw materials. The new technique can make the co2 polymerization reaction with the production of traditional foam plastics raw materials, in the improvement of the performance of the product at the same time, to the introduction of the carbon dioxide "circle of industrial raw materials.
Plastics industry, the polyurethane foam has certain elasticity, are widely used as shockproof packaging materials, sound-absorbing materials and water absorbing material, etc. The main composition of polyurethane for multivariate alcohol and isocyanate. Under the action of super catalyst, carbon dioxide can open chemical bonds become carbon dioxide based, "embedded" polyol, aggregated into polycarbonate polyol, eventually generated with isocyanate polyether carbonate type polyurethane. Based on polyether carbonate type polyurethane foam plastics, the composition of the mechanical properties, hydrolysis resistance, heat resistance, oxidation resistance, wear resistance, higher than the traditional polyurethane materials.
Foam production is based solely on past oil as raw material, with this new technology, carbon dioxide can be instead of a quarter of the oil consumption. Add catalyst will not cut in the production process, production equipment is put into use for a long time, carbon dioxide can be obtained from the upstream enterprise such as thermal power plant of cheap. In the long run, the carbon dioxide as industrial raw material, not only more environmentally friendly than the traditional technology, but also has to be reckoned with business competitiveness. Families and strong plan every year to produce 5000 tons of polyether carbonate type polyurethane foam plastics. Next, they expanded to the whole plastic industry is trying to apply technology, along the development direction, the plastics industry in the future is expected to completely get rid of the dependence on oil.
