In September 2021, the 2021 National Plastics Coloring and Masterbatch Academic and Technical Trade Exchange Conference and the 28th China Masterbatch Industry Annual Conference were successfully held in Boao, Hainan.
2021 is the centenary of the Communist Party of China and the beginning year of the "14th Five-Year Plan." As an annual conference for technical exchanges and collaborative development in the masterbatch industry, the success of the conference relies on the efforts of all the main and co-sponsoring units, one of which is Nanjing KY Chemical Complete Equipment Co., Ltd. (hereinafter referred to as Nanjing KY), an organizing co-sponsor that attended the conference.
On the afternoon of September 27, 2021, Lei Nianchen, the R&D director of Nanjing KY, presided over the report. As a veteran of 20 years in the twin-screw extruder industry, Lei has been responsible for product design and sales at different periods of time, and he devoted himself to building the best China pvc twin screw extruder. This year's conference started from three aspects: KY equipment's new technology and products, the basics of screw combination, and the improvement process and cases of screw combination.
At this report meeting, Lei also introduced to everyone the market application and promotion of Nanjing KY's higher torque twin-screw extruder and twin screw extruder elements.
The newly designed HK transmission box raises the torque series from 8.8Nm/cm³ to 13Nm/cm³, while the higher-grade SK plus twin-screw extruder series products increase the torque from 11Nm/cm³ to 18Nm/cm³.
In addition, Nanjing KY has also made progress in design and processing, and has improved the spiral waterways of the barrel, the sealing technology of the steel beads, which can effectively improve heat exchange efficiency and avoid barrel deformation. The heating rod's heating can greatly improve heating efficiency while reducing energy consumption. Nanjing KY's component composite coating patent technology has advantages such as low friction coefficient, high surface hardness, excellent coating toughness, adhesion, and lubricity.
In the second part of the meeting, Lei introduced the basic content of screw combination, including the screw structure segmentation, the targets, influencing factors, and difficulties of each area, as well as the pressure balance, temperature balance, and difficulties of the screw structure as a whole.
Finally, Lei, on behalf of Nanjing KY, showed everyone the improvement process of screw combination and conducted a case sharing.
