As a daily necessity with high demand, cotton swabs have a large demand for thermal energy in their production process, including cotton fiber processing, molding, bonding, disinfection and drying. Traditional heating methods (such as electric heating and boilers) have high energy consumption and low thermal energy utilization efficiency, while high-temperature heat pump technology can efficiently and accurately meet the thermal energy needs of the production process, while significantly reducing energy consumption and carbon emissions.
Heat demand in cotton swab production
The main processes and corresponding thermal demands of cotton swab production are as follows:
- Cotton fiber processing
- Process: Cotton fibers are washed and bleached to remove impurities and ensure hygiene.
- Temperature requirement: 40~60°C (hot water washing).
- Heat source requirement: low-temperature hot water.
- Bonding molding
- Process: Bond the cotton fibers to the rod body through hot glue or adhesive to ensure the stability of the product structure.
- Temperature requirement: 50~80°C.
- Heat source requirement: stable medium-temperature heat source.
- Disinfection and sterilization
- Process: Sterilize the finished cotton swabs at high temperature to ensure aseptic production.
