Changkong Nanotechnology Co., LTD., approved by the State Administration for Industry and Commerce, is located in Xi 'an High-tech Zone. The company aims to become a leading enterprise in the industry of advanced polymer modified plastic technology and nanostructure interface technology. The development goal is to create the first stock in the advanced nanocomposite new material industry. It has successively won the honorary titles of "National specialized and special new small Giant Enterprise", "National high-tech Enterprise", "Provincial specialized and special new Enterprise", "Provincial reserve Enterprise to be listed", "Provincial Gazelle Enterprise" and "Ministry of Industry and Information Technology Leading Enterprise". Listed in the key industry chain of Shaanxi Province "stuck neck" to fill the key technology project, selected as Shaanxi Province Qinchuangyuan key technology enterprises, but also Shaanxi Province key industry chain (coal to olefin aromatics deep processing industry chain) key technology enterprises. The company's research and development team has independently developed polymer materials "depolymerization machine" for nearly 30 years to break the international monopoly position, and can be rearranged and combined after the molecular chain is reunited to achieve the new technology of modified synthesis of different resin substrates and nanoscale fillers. The core advantage is to rearrange the molecular chain through the depolymerization machine to solve the problem of difficult dispersion of nanoscale materials, while realizing the network structure and interface modification technology, which is both rigid and toughness in the application, opening a thinner era for polymer composite materials, while reducing manufacturing costs, and solving a number of card neck market applications. This breakthrough in basic science and technology has improved the application of polymer materials in a wide range of industrial markets. 1, increase the proportion of filling materials in the traditional materials of the inner volume, reduce the wall thickness, and maintain high rigidity and toughness, breaking the cost bottleneck of the plastic industry. 2. Solve the core technology that has an internal skeleton that cannot be blown. 3. Nanocellulose dry powder preparation technology is the key support technology for achieving the "double carbon" goal and bio-based green composite materials.
