Shanghai Public-private partnership Fuxin Chemical Factory produced precipitated calcium carbonate. In July, the public-private partnership Zhengteng Rubber Factory discovered that when it was used to manufacture running shoes outsole, it was found that after the cut, there was a small air hole in the middle and the quality of the new calcium carbonate was considered to be a problem. After many contacts and discussion of the reasons, no results were obtained. The Chemical Materials Industry Association submitted this technical issue to the China Chemical Industry Association and asked for help. For this purpose, the Chinese Chemical Industry Association invited relevant persons from inside and outside the society to open a special seminar on September 7. Participants include Sun Ruigeng and Ling Dingzhong.
