Overview
Paper and Cardboard Smoothness tester (model NBC-5636) is a smart special instrument designed based on the working principle of Buick Bekk smoothing instrument, which is used to detect the surface smoothness of paper and Cardboard. It uses a measurement and control system composed of High Accuracy pressure sensor, oil-free Vacuumpump, volume block and solenoid valve to achieve mercury-free measurement, and is loaded by lever mechanism and unloaded by cam mechanism. It has test conversion, display, memory, printing and data processing functions, easy operation and stable performance.
Features
1. Oil-free Vacuumpump, oil-free and pollution-free
2. Preload time selection function, 60 seconds preload automatic control can be selected
3. Fast measurement, optional small volume cavity, measurement time is only one-tenth of the large volume cavity
4. The volume cavity automatically determines and switches, and can automatically handle situations less than 15 seconds, 15-300 seconds, and greater than 300 seconds
5. Two-sided difference automatic calculation function, can measure the smoothness of front and back sides and calculate the two-sided difference
6. Good sealing, in line with national standards
7. Modular integrated printer, easy installation, low failure rate, direct printing
Principle
The instrument is based on the working principle of the internationally used Buick Bekk smoother, and the measurement and control system is composed of High Accuracy pressure sensor, oil-free Vacuumpump, professional volume block and solenoid valve to achieve mercury-free measurement. On the mechanical structure, the lever mechanism is applied to load and the cam mechanism is unloaded to automatically control the vacuum degree change, the smoothness of the measurement paper or Cardboard under specific pressure, and the data is automatically processed.
Applications
Paper companies, printing companies
Standards
GB/T456、ISO5627
Steps
1. Prepare the sample and place it in the test area
2. Select the preload time (optional 60 second preload function)
3. Start the instrument and automatically perform clamping and pressurization
4. The instrument automatically determines and switches the volume chamber for measurement
5. After the measurement is completed, the data is automatically displayed and can be output through the printer
6. If two-sided difference test is required, the front and back sides of the repeability measurement
Notice
• Ensure that the working environment temperature is within the range of 20 +/- 10 ° C
The working environment humidity should be less than 85%
• Check whether the sealing of the instrument meets the standards before use
• Avoid operating in contaminated environments to maintain oil-free and pollution-free characteristics
Maintain the printer regularly to ensure normal output
