Overview
The JH-YSY-A type printing adaptability tester is a general-purpose paper and paperboard printing adaptability tester. It is specially developed for paper printing bristling testing according to the new "paper printing adaptability" international standard. It is computer-controlled and the test results are compatible with AIC2-5, IGT A1-3 and IGT A2-3. The instrument adopts professional electromechanical technology and performs well in function and test accuracy. It is randomly equipped with high-speed ink leveling equipment, standard ink dispenser, aluminum printing disc, etc. Suitable for all kinds of offset plate, letterpress plate and gravure printing paper and Cardboard simulation printing test, is the paper testing center, research institutes, universities and related papermaking enterprises ideal printing hair detection instrument.
Features
1. Accurate control system: High Accuracy motor and computer program control are used to ensure that the fan pendulum speed is increased accurately, and the error between the actual speed and the theoretical value during the test is kept within 1%.
2. Excellent reproducibility and Repeatability: Automatic, accurate printing pressure and reasonable mechanical design ensure good reproducibility and Repeatability of the instrument.
3. Easy to use and easy to operate: LCD Chinese display, friendly man-machine interface operation, automatic test completion.
4, Easy Measurement, calibrating: Instrument built-in Measurement, calibration system, the user or Measurement, calibrating department can be based on the instructions of the instrument Precision Measurement and calibration.
Principle
The instrument drives a fan-shaped pendulum at a set speed while applying adjustable printing pressure to simulate printing on paper samples. The printing adaptability of paper is assessed by measuring the critical speed at which the paper begins to ink disbonding paper fibers at specific speeds and pressures.
Applications
Paper testing centers, research institutes, universities, and related papermaking enterprises
Standards
ISO3782、GB/T2679.15、GB/T22365、QB/T1058、TAPPI514 and 575、SCAN P 63:90
Steps
1. Prepare paper samples and inks.
2. Spreader inks evenly on the aluminum printing plate using the randomly equipped high-speed uniform ink equipment and ink feeder.
3. Fix the paper sample on the instrument.
4. Set test parameters through the LCD Chinese interface, such as printing pressure (standard 350N +/- 10N) and speed range (0.2~ 6 m/s).
5. Start the test, and the instrument automatically completes the simulated printing process.
6. Record or read the test results such as the critical speed when the paper is pulled.
Notice
• Power supply voltage of the instrument is AC220V, 50Hz, please make sure the power supply matches.
• Please read the manual carefully before use, follow the instructions for operation and Measurement calibrating.
• When testing, ensure that parameters such as printing pressure are set accurately to ensure the reproducibility and Repeatability of the test results.
• Instrument mass of about 50kg, handling and placement should pay attention to safety.
• Keep the instrument clean and keep random accessories such as aluminum printing discs, inkers, etc.
