In recent years, with the high price of international oil, biodiesel as an alternative energy source is widely popular. And as the biodiesel industry gradually heats up, cheap glycerin emerges in large quantities. It is understood that the biodiesel production process will produce a large amount of glycerin by-product. Every 10 tons of biodiesel production will produce 1 ton of glycerin. This will have a very big impact on the traditional glycerin production enterprises. Many traditional glycerin producers will be forced to close down. The increase of the supply of cheap glycerol by-products will certainly drive the rapid development of new glycerol-based raw material industries. The preparation of epichlorohydrin by “glycerol method” has become a hot spot in the industry. Last year, Dow Chemical and Solvay announced the construction of large scale epichlorohydrin production plants using “glycerol method” almost simultaneously. And several manufacturers have implemented or launched the construction plan of epichlorohydrin using “glycerol” process in China. A global climax of epichlorohydrin development has been formed. According to the experts of China Epoxy Resin Industry Association, “glycerol method” will become the main character of the development of epichlorohydrin. Epichlorohydrin is expected to become the largest application area of glycerol. At […]

3D Printing Technology May Change Human Life
From self-repairing pipes to printed organs, to t-shirts that are bulletproof. These very avant-garde-sounding things are likely to arrive with the new 3D printing technology. The new 3D printing technology was the hottest topic at the TED conference held in Vancouver, Canada in April of this year. Five of these trends are particularly noteworthy. 3D printing technology is likely to change people’s lives in the future. Biz Stone, co-founder of Twitter, predicted that Nike is likely to become a pure software company in the next decade, thanks to 3D printing. In the future, traditional product manufacturers won’t have to provide users with actual products. Instead, they will release copyrighted 3D-printed blueprints. Users can simply print the product at home or at a nearby 3D printing store. Digital 3D printing factories are also growing rapidly around the world. This means that traditional forms of production are beginning to shift. Direct digital manufacturing can reduce global sourcing, manufacturing costs, provide more local jobs, and also help to compress production costs. 3D printing is far more creative than people can imagine. Custom materials will lead to a broader scope of development and numerous innovative experiences. Already, doctors have successfully created a tool for […]
PU Foam Can Provide Insulation for Houses
While providing the ideal insulation for wooden houses in Scandinavia, the issue of controlling heating costs has to be taken into account. Two companies have already jointly conceived a solution based on polyurethane rigid foam. Two wooden beams with cross sections of 98 by 47 mm and 40 by 47 mm were placed in a mold and the gap between the two beams was filled with a liquid polyurethane system solution. The mold was then sealed. and cured at a temperature of about 45ºC. After a short period of time, the finished polyurethane mullions can be removed from the molds. The stability of the mixture is ensured by the fact that the polyurethane system adheres very well to the underside of the wood. This technology prevents the creation of thermal bridges between the internal space and the surface. Thus, the insulation solution is greatly improved. The Norwegian Intellectual Property Office has confirmed in writing that it will grant a patent for the invention of this technology. There are parts of the building envelope where relatively dense heat flow and low internal surface temperatures are formed by the temperature difference between the interior and exterior of the building. These parts become […]
