UV light is used to trigger the curing process in water-cooled curing systems. The UV light is generated by a UV lamp or LED light source, which emits UV light. The UV light then travels through a window of quartz or fused silica into the curing chamber. A photoinitiator in the UV-curable coating or adhesive captures the UV light, which triggers a chemical reaction to begin the curing process. The curing process releases heat, which can increase the temperature in the curing chamber. To prevent overheating and damage to the curing system, water runs through the curing chamber to cool down the heat released during the curing process. The water temperature is adjusted to maintain a stable curing temperature, which can help ensure consistent and effective curing.
In summary, water-cooled curing systems use UV light to trigger the curing process, which releases heat that is cooled by water to maintain a stable curing temperature. This process allows for efficient and effective curing while avoiding the risk of overheating and damage to the curing system.
