Computer Buick smoothness tester

Suitable for measuring smooth paper and paperboard,It is not suitable for paper and paperboard with a thickness greater than 0.5mm or a high degree of breathability, and it is not suitable for rough paper or paperboard. Test method for the measurement of the surface of the paper affixed to the glass plate is placed, a certain pressure to produce a partial vacuum, inhalation of air and air through the contact surface, measuring the vacuum degree within the prescribed scope change time, in seconds (S) said.

Product features

High precision pressure sensor and German oil free vacuum pump, high precision electromagnetic valve and stainless steel vacuum vessel are adopted to ensure the sealing performance of the instrument, and the test result is accurate, stable and repeatable.

Chinese LCD display interface, according to the smooth degree of a third test, convenient, automatic completion of testing.

Test data statistics processing function, result automatic memory, display and printer print test result.

Test description

With uniform sampling equipment from the sample cut from the standard sample (60mm * 60mm), the measurement of the surface samples attached to the glass plate placed on the head, and then put on the sample pad, pressure (100 ± 2) KPa, and then open the instrument testing, such as testing time more than 300S, use a small volume and if time is less than 15S, you should test the vacuum time required from 50.66 to 29.33KPa, the sample from the load to the timing start time should be approximately 60S. The smoothness of each sample should be the arithmetic mean of the 10 measured results on the right and back, expressed in seconds.

Note: the sample should be no wrinkles, creases, visible cracks or other defects of paper.
