The six-station viscometer is manufactured in accordance with the national standard GB/T4851-1998 of the People's Republic of China. The six-station viscometer is suitable for pressure-sensitive adhesive tape and other products for adhesive test. The six-station viscometer is an essential instrument for product quality testing of related companies.
Six-station holding adhesive tester works: The test sample is affixed to vertical plates hanging in the test frame, hanging a lower end of a predetermined weight of the weights, a certain period of time after removal of the sample viscosity or the amount of displacement from the sample is completely The time required to determine the ability of the adhesive tape to resist pull-off.
Six-station holding adhesive tester instrument structure: mainly by the timing means, the test plate, the plate loading portion, weights, and a standard rack the pressure roller and the like.

Six-station sticky tester operation method
1 Place the instrument horizontally, turn on the power switch, and place the weight in the slot below the hanger.
2 Unused stations can be stopped by pressing the “Close†button. Press the “RESET†button to re-time.
3 After removing the 3 to 5 ring adhesive tape on the outer layer of the tape test strip, unwind the sample roll at a rate of about 300 mm/min (the strip sample is also peeled off at the same rate), every About 200mm, a sample with a width of 25 mm and a length of about 100 mm is cut in the middle of the adhesive tape. Unless otherwise specified, the number of samples per group is not less than three.
4 Wipe the test plate and the loading plate with a wiping material and a cleaning agent, then dry it carefully with a clean gauze, and wash it three times. Above, until the working surface of the board is visually inspected and cleaned. After cleaning, do not touch the working surface of the board with your hands or other objects.
5 At a temperature of 23 ° C ± 2 ° C, relative humidity of 65% ± 5%, according to the size specified in Figure 2, the sample is pasted parallel to the longitudinal direction of the plate in the middle of the test plate and the loading plate next to each other. The sample was rolled at a speed of about 300 mm/min with a press roll. Note that when rolling, it can only be applied to the specimen with the force generated from the quality of the press roll. The number of rolling can be specified according to the specific product conditions. If there is no regulation, the rolling is repeated three times.
6 After the sample is pasted on the board, it should be placed at a temperature of 23 ° C ± 2 ° C and a relative humidity of 65% ± 5% for 20 min. Then the test will be carried out. The plate is fixed vertically on the test stand, and the load plate and weight are lightly connected by pins. The entire test rack is placed in a test chamber that has been adjusted to the required test environment. Record the test start time.
7 After reaching the specified time, remove the heavy objects. Use a graduated magnifying glass to measure the amount of displacement of the sample down to the nearest 0.1 mm; or record the time the sample has fallen off the test panel. The number of times is greater than or equal to 1h, in min, and less than 1h in s.
Six-station viscometer test result
The test results are expressed as the arithmetic mean of the displacement or shedding time of a set of samples.
Six-station sticky tester precautions
1 This test shall be carried out in full compliance with GB/T4851-1998 and related standards.
2 Turn off the power and keep it clean after use. Models are subject to change without notice.
