Advantages of Carbon Fiber Heating Tubes in Paint Industry

In the paint industry, carbon fiber infrared heating tubes offer several advantages over traditional heating methods such as combustion heating, heat pump heating, or conventional metal heating tubes. Here are the key benefits:

Environmental Protection, Safety, Simple Installation, Space Saving

  1. Environmental Protection, No Pollution:
    • Combustion heating generates secondary pollutants like carbon dioxide, sulfur dioxide, and solid particulate matter, polluting the air. In contrast, infrared heating tubes operate through electric heating, transferring heat without producing any secondary pollutants.
  2. Safety:
    • There are no fire hazards associated with combustion. Traditional combustion heating often uses diesel or wood scraps, requiring significant space for material storage, thereby increasing safety management burdens and costs for businesses.
  3. Simple Installation:
    • Compared to traditional heating methods, carbon fiber heating tubes heat objects directly without the need for hot air ducts, significantly reducing heat loss and equipment footprint.
  4. Space Saving:
    • Carbon fiber infrared heating tubes occupy minimal space compared to combustion chambers, heat pump rooms, or hot air ducts.
  5. No Instantaneous Surge Current:
    • Metal heating tubes often experience a surge current upon startup, reaching up to 4.8 times the rated current, demanding higher electrical component requirements. Carbon fiber infrared heating tubes do not experience such instantaneous surge currents, ensuring reliable operation.

High Drying Efficiency, Time Reduction, Cost Savings

  • Time Saving and Cost Reduction:
    • For water-soluble paints, drying using convection heating typically takes twice as long as oil-based coatings. In contrast, infrared radiation heating can raise the temperature of paint layers to 80 degrees Celsius within 5 minutes, rapidly evaporating moisture from the coating, and achieving drying within 10 minutes.

Improved Paint Surface Quality

  • Enhanced Surface Gloss:
    • Carbon fiber infrared heating tubes heat the paint without relying on air convection, thereby reducing exposure to external air. Practical results demonstrate that infrared radiation heating produces paint surfaces with significantly higher gloss compared to traditional heating methods. This improvement is attributed to infrared heating starting from within the paint film, avoiding defects such as pinholes, bubbles, or orange peel texture that often result from traditional surface-to-interior heat transfer methods.

Additional Knowledge Expansion – Analysis of Common Paint Defects: Pinholes

  • Analysis of Paint Defects – Pinholes:
    • Pinholes are needle-like small holes on the paint film, typically with diameters ranging from 80 to 120 micrometers. The paint film around pinholes becomes detached from the substrate, allowing air moisture or external moisture to easily penetrate the paint film. This leads to corrosion starting from the substrate, compromising adhesion and corrosion resistance of the product’s appearance.

Main Reason:

  • Rapid solvent evaporation on the paint surface leads to quick surface drying, reducing internal paint film gaps. This prevents complete solvent evaporation from the remaining gaps, resulting in breaches in the paint film and the formation of pinholes or needle holes. Drying the paint film from the substrate bottom rather than from the surface inwards would mitigate this issue, thereby enhancing paint surface quality.
