Accessoriess
Test chamber body: Used to contain the sample and solution, usually designed with special corrosion-resistant and acid-alkali resistant materials.
Stirring device: Ensures thorough mixing of the solution during heating, leading to more accurate experimental results.
Temperature control system: Includes a PID digital display temperature controller for precise control and maintenance of the solution temperature within the container, with a temperature control accuracy of up to ±0.1℃.
Experimental chamber: Typically designed as a three-compartment system for acid and alkali experiments, including a clean water compartment, an alkaline solution compartment, and an acidic solution compartment.
Sample holder: Used to fix the sample and prevent it from moving or deforming during the experiment.
Drainage device: Facilitates the drainage of the solution after the experiment for equipment cleaning and maintenance.
Heating element: Such as a heating tube, provides the necessary heat to the solution to reach the set experimental temperature.
Test Procedures
Preparation: Check the equipment, calibrate the parameters (temperature, concentration, time), and prepare the acid and alkali solutions.
Sampling: Cut standard samples and weigh and record their initial mass.
Immersion: Immerse the samples completely in the solution, ensuring no air bubbles and no overlapping.
Testing: Start the equipment and conduct aging according to the set conditions (e.g., 60℃, 3 days).
Removal: After the specified time, remove the samples, clean and dry them, weigh them, and test for changes in performance.
