Background
The photo-curing coating is convenient to use and excellent in performance, and gradually becomes a novel coating which is widely used. The curing process of the photocureable coating is a polymerization crosslinking process, after the photocureable coating is irradiated by a photocureable light source, a photoinitiator in a coating system is excited and decomposed to generate free radicals, and the active free radicals impact double bonds in the photocureable coating and react with the double bonds to form a chain lengthening chain. The reaction continues to extend, so that double bond segments in the reactive diluent and the oligomer are cracked and mutually cross-linked to form a film. In addition to the above-described positive reaction, the collision of the radicals also returns from the excited state to the ground state, and the final result of the reaction is solidification to form a film.
The photoinitiator in the photocuring coating is a substance which can absorb radiation energy and generate a reactive intermediate with initiator polymerization capacity through chemical change, and is also a main component required by any curing system. In order to increase the purity of the photoinitiator, a crystallization step is required in the manufacturing process of the photoinitiator. The crystallization of the photoinitiator is carried out in a dedicated crystallization kettle. However, when the photoinitiator is crystallized in the conventional crystallized gold, the crystallized photoinitiator is easily adhered to the inner wall of the crystallization kettle, and thus the crystallization efficiency is reduced, and the entire crystallization kettle is severely blocked, thereby causing a shutdown for maintenance. Therefore, there is a high necessity for a crystallization kettle which is less likely to cause excessive adhesion of the photoinitiator to the inner wall.
