The technical requirements and testing methods of the drk105 smoothness tester (hereinafter referred to as the smoothness tester) conform to the international standards ISO5627 “Determination of Smoothness of Paper and Cardboard (Buick Method)”, QB/T1665 “Paper and Cardboard Smoothing Tester” and other standards. It is a necessary instrument for the detection of various high-smooth paper.
The drk105 smoothing tester is used for the testing of high smooth paper and cardboard. It should not be used to test materials with a thickness of more than 0.5mm or paper or cardboard with high air permeability, because the amount of air passing through the sample may cause unrealistic results. The Derek smoothness tester (also known as the paper smoothness tester) uses a high-precision vacuum sensor to measure the vacuum degree of the vacuum container, thereby replacing the mercury pressure gauge, so this instrument is a mercury-free smoothness tester; it adopts imported The vacuum mercury extracts the vacuum from the vacuum container, which can reach the required vacuum degree in a very short time, and is controlled by the single-chip microcomputer; it also has a powerful data processing function: not only can the smoothness value of a single sample be measured and automatically stored, And it can count the experimental data of multiple samples in the same group, and can count the maximum value, minimum value, average value, standard deviation and coefficient of variation of the same group of samples. These data are stored in the data memory and can be digitally Tube display; in addition, the instrument has a printing function. Under a specific contact state and a certain pressure difference, the time required for a certain amount of air to leak from the atmosphere between the sample surface and the annular surface, expressed in seconds (s). The longer the time, the better the paper smoothness, the higher the smoothness, the better the printing quality. Therefore, to obtain satisfactory printing quality, smoothness is a necessary condition.
