Water-cooled High-Temperature PI Oven, Anaerobic Oven, PI Curing, Dust-Free Oxygen-Free Bake Process
The synthesis process for Pi commonly employs a two-step method. The first step involves the condensation of dimeric anhydrides and dimeric amines at low temperatures to produce polyamide PAA. The second step entails cyclization of PAA into Pl via chemical imidization or thermal imidization.
Hydrazination is further divided into solid-phase hydrazination and solution hydrazination. The former, solid-phase hydrazination, is commonly used in the preparation of PI films, where PAA solution is cast into a film and then heated for hydrazination. Solution hydrazination involves adding azeotropic solvent to the PAA solution, heating it to reflux, and using the vaporization of the azeotropic solvent to remove water produced during the reaction, thereby promoting further reaction. At room temperature to 150°C, the primary processes are the removal of oxygen and water; from 150°C to 320°C, the main processes are the volatilization of residual solvents within the film and dehydration cyclization. The second stage is the main temperature range for the reaction and the critical stage for the transition of PAA structure to PI structure. Higher hydrazination temperatures are beneficial for the volatilization of residual solvents within the film and the progression of dehydration cyclization reactions, resulting in PI original films with an orderly structure.
