118mm 24v 300w Carbon Firber Clear Heat Lamp for High-Temperature Curing of Ink from Goldisgood application
  1. Product Specifications and Their Significance
    • Dimensions: The 118mm size of the lamp is relatively compact. In the context of high-temperature curing of ink, this compactness can be advantageous in certain setups where space is limited. For example, in a printing press with a confined area around the ink curing section, the 118mm lamp can fit in without taking up excessive space while still providing the necessary heat.
    • Voltage and Power: Operating at 24V and having a power output of 300W, this carbon fiber clear heat lamp offers a specific level of energy for generating heat. The 24V voltage is a relatively low voltage, which can be safer in some applications compared to higher voltages. The 300W power is sufficient to raise the temperature to the levels required for high-temperature curing of ink. Carbon fiber heat lamps are known for their efficient energy conversion, meaning a larger portion of the electrical energy is converted into heat that can be used for ink curing.
    • Light Emission: The “Clear” description implies that the lamp emits heat without significant obstructions. The clear emission of infrared radiation (as carbon fiber lamps typically emit infrared heat) is crucial for the high-temperature curing of ink. It can penetrate the ink layer deeply, reaching the components that need to be cured, such as resins and solvents in the ink.
  2. Application in High-Temperature Curing of Ink
    • Ink Curing Process
      • Solvent Evaporation: When the infrared heat from the lamp is applied to the ink on the printed surface, it causes the solvents in the ink to evaporate quickly. This is a crucial step in the ink curing process as it helps to harden the ink. The 300W power of the lamp provides enough heat to ensure that the solvents are removed in a timely manner. For example, in a flexographic printing process, solvents need to be evaporated to prevent issues like ink smearing or poor adhesion, and this lamp helps achieve that.
      • Resin Cross – Linking: The infrared heat also promotes the cross – Linking of resins in the ink. This chemical reaction is what gives the ink its final hardness and durability. The clear carbon fiber lamp’s infrared radiation can penetrate the ink to the right depth to trigger and accelerate this cross – Linking process, resulting in a high – quality, long – lasting ink finish.
    • Even Heat Distribution Benefits
      • Uniform Ink Finish: The compact 118mm size of the lamp, along with its design, helps in distributing heat evenly across the inked surface. This is vital for achieving a consistent ink finish. Uneven heat can lead to different drying rates in various parts of the printed surface, resulting in an inconsistent appearance such as blotches or streaks. The even heat distribution provided by this lamp helps to avoid such issues and ensures that the ink cures uniformly across the entire surface.
      • Reduction of Hot Spots: Hot spots, where the ink can overheat and potentially be damaged, are a concern in ink curing. The design of this lamp helps to minimize the occurrence of hot spots. By evenly spreading the infrared heat, it reduces the risk of over – curing or burning the ink in specific areas.
