(2) The academic idea and method of preparing stress-free blank by colloid forming are put forward. Academic thought points out that although the green body with uniform density can be obtained by in-situ solidification molding of colloid, it is easy to produce internal stress in the process of liquid-solid transformation, and the internal stress will develop, inherit and vary in the process of drying, glue discharge, sintering and machining. It is pointed out that overcoming the stress in the blank will be an important development direction of ceramic colloid forming technology in the future, which has been widely recognized by colleagues at home and abroad. At the same time, he obtained 2 invention patents in China and the National Natural Science Foundation 1 item.
(3) Successfully developed the first international ceramic colloid injection molding machine and industrial prototype, and obtained two China invention patents through two expert appraisals organized by the Ministry of Education. Up to now, an industrial base of more than 9,000 square meters has been established.
(4) For the first time, the mechanism of crack formation in the process of liquid-solid transition of ceramic concentrated suspension was revealed, and two methods to avoid crack formation were put forward, and two domestic invention patents were granted. This achievement was evaluated by Professor Gauckler of Swiss Federal Institute of Technology as "the most important achievement in the field of materials, which greatly deepened the basic understanding of colloid chemistry of materials".
(5) A new technology of rapid and uniform mixing and controllable solidification of ceramic suspension was invented, which was patented by China 1. In this technology, the suspension is divided into two or more groups, and each group is kept for a long time and will not solidify. When the components are quickly mixed evenly in a short time and the suspensions with different characteristics react and solidify, this method is universal, which is another major breakthrough after the new process of ceramic colloid injection molding and lays a solid foundation for the establishment of production line.
(6) Invented the general preparation method and equipment of high-performance ceramic microbeads (0. 1-3 mm), which was highly appraised and affirmed by the 863 expert group. The whole production line has all independent intellectual property rights, and has passed three results appraisal organized by the Ministry of Education and the Science and Technology Department of Hebei Province. Due to advanced technology, the project was acquired by Saint-Gobain, a fortune 500 company in the world, in 2005. China obtained 1 invention patents.
(7) A gel point testing device was invented and made by ourselves, which can test the relationship between reaction time and temperature under different pressures in the process of gel reaction online, providing an experimental testing means for studying gel reaction kinetics, and obtained the invention patent of China 1 item, and published many papers1item with this device.
(8) A new ceramic composite dielectric material with high power and low voltage starting was invented. The starting voltage is reduced from 8000V to 1000V, the ozone output is increased by more than 10 times, and the manufacturing cost is greatly reduced. Applied for two invention patents in China. At present, several ozone generator devices have been successfully developed. Obtained two invention patents in China.
