PT. TIARA SERVICE CENTREHisaka pH Control System is an advanced optional system for dyeing machines that simultaneously controls pH and temperature during the dyeing process. Using the HAC (Control Device), the system continuously detects and adjusts pH values through automated acetic acid injection, ensuring consistent color reproducibility and eliminating operator dependency in pH-dependent dyeing applications.
Automatic pH control eliminates manual inconsistencies and operator dependency. The HAC device maintains precise pH values throughout the entire dyeing cycle, ensuring batch-to-batch consistency for pH-sensitive dyes.
Two-axis control system manages both pH and temperature at the same time. This integrated approach ensures optimal dyeing conditions are maintained throughout the process, reducing cycle time and improving efficiency.
Nylon dyeing with acid dyes highly depends on pH conditions. The pH Control System maintains appropriate pH values in the entire temperature range, enhancing color reproducibility and reducing rework or customer complaints.
The pH Control System consists of integrated components that work together to automate pH monitoring and adjustment:
Cools the sample from the dyeing machine for accurate pH measurement at stable temperature.
Continuously detects the current pH value of the dye liquor in real-time.
Chamber where pH measurement takes place under controlled conditions.
Stores acetic acid solution for pH adjustment and injection into the dyeing machine.
Precisely controls the feeding volume and speed of acetic acid injection based on HAC calculations.
Main controller that simultaneously manages pH and temperature, calculating required acid dosing.
The HAC Control Device maintains pH stability through an automated feedback loop:
Hisaka pH Control System is ideal for dyeing facilities that:
