New type of composite resin is made into recyclable turbine blades

Science and Technology Daily, Beijing, August 23 (Intern reporter Zhang Jiaxin) Wind power is an increasingly popular renewable energy source. However, how to deal with the giant turbine blades that convert wind energy into electrical energy is a problem. At the autumn annual meeting held on the 23rd, American scientists reported a new composite resin that can be used to create these behemoths, and after recycling can be used to create new turbine blades or various other products, including tables, cars, cars, cars, cars, cars, cars, cars, cars, cars, cars, cars Tail lights, diapers, and even bears.

"The beauty of our resin system is that at the end of its usage cycle, it can be dissolved, and then released from any substrate it is, so that it can be used repeatedly." The doctor said, "This is the goal of the circular economy."

The length of the wind turbine made of glass fiber can reach half a football field. Although some companies have found a way to recover glass fiber into low -value materials, most of the discarded leaves are eventually sent to the garbage landfill.

The researchers created a new turbine material by combining glass fiber and plant derivatives and synthetic polymers. The panel made of this armoplastic resin is strong and durable, and can be used for turbines or cars. The researchers dissolved the panel in the fresh monomer, removed the glass fiber in physics, and cast the material into new products of the same type. The recasting panel had the same physical properties as its predecessor.

In addition to the new wind turbine blades, this new type of resin can also be used for various other applications. By mixing the resin with different minerals, the research team produces artificial stones that can be converted into household items, such as tables and bathroom sinks. Researchers can also shatter the recycled materials and mix it with other plastic resins and mold them to make items such as laptops and electric tools.

This material can even be upgraded to higher -value products. The digestive thermoplastic resin in alkaline solutions releases polymethyl acrylic (PMMA), which is a common acrylic material for windows, car taillights and many other items. Increasing the digestive temperature can convert PMMA into polymethyl acrylic, which is a high water absorption polymer for diapers. Alkaline digestion also produces potassium lactate, potassium potassium can be purified and made into candy and sports drinks. "We recycled potassium -grade lactate and made bear fudge with it. I ate it." Daogen said.

Researchers have proved that this resin has the physical properties suitable for wind turbine, and they hope to create a medium -sized blades used on on -site testing.
