UV Curing Production Process
UV curing technology is a process that utilizes ultraviolet energy for photopolymerization, widely used for rapid curing and forming of various materials. In the field of hydrogels, this technology particularly demonstrates unique advantages and broad application prospects.
Principle and Mechanism
The basic principle of UV curing is to activate photoinitiators through UV light exposure, triggering photochemical reactions of monomer molecules, which ultimately form a stable polymer network structure. Common UV light sources include 365 nm long-wave UV (UVA), with curing operations carried out using UV crosslinking devices. Additionally, some studies explore the importance of curing in an oxygen-free atmosphere to achieve more complete curing effects.
Features and Advantages
