Alumina Ceramics:

The polycarbonate used in the Alumina Ceramic industry is mainly synthesized from bisphenol A and phosgene. Its main chain contains a benzene ring and four-substituted quaternary carbon atoms, which increases rigidity and heat resistance. Tm=265-270℃, Tg= At 149℃, it can maintain good mechanical properties at 15-130℃. It has excellent impact resistance and transparency, stable dimensions, creep resistance, and performance better than polyester. It is an important engineering plastic. However, polycarbonate is prone to stress cracking and hydrolysis when heated, so it should be fully dried before processing.
The preparation methods of polycarbonate include transesterification method and direct phosgene method. The principle is similar to the transesterification method for producing polyester polyester. Bisphenol A and diphenyl carbonate melt polycondensation, carry out transesterification, continuously eliminate phenol under high temperature and reduced pressure conditions, and increase the degree of reaction and molecular weight.
The transesterification method needs a catalyst and is carried out in two stages: the first stage, the temperature is 180-200℃, the pressure is 270-400Pa, the reaction is 1-3h, the conversion rate is 80%-90%; the second stage, 290-300℃ , Below 130Pa, deepen the degree of reaction. The starting diphenyl carbonate should be excessive. After transesterification, the phenol is discharged. The phenol discharge is used to adjust the ratio of the two groups and control the molecular weight. Phenol has a high boiling point, and it is not easy to remove it from a high-viscosity melt. Compared with polyester polyester, polycarbonate has a much higher melt viscosity, such as a molecular weight of 30,000 and a viscosity of 600 Pa·s at 300°C, which requires higher mixing and heat transfer of reaction equipment. Therefore, the molecular weight of the transesterification polycarbonate is limited, and it does not exceed 30,000.
