How to operate the sticky tape testing machine?

How to operate the sticky tape testing machine? Some customers do not know how to operate after purchasing the adhesive tape initial tack testing machine. Haida is the manufacturer of the initial tack testing machine. Here, we share with you the operation method of the tape tack testing machine. The following are the details:

1. Use a level meter to fix the ball device horizontally on the test bench . The inclined plane takes a standard angle of 30 ° , and when necessary, it can take 20 ° or 40 °.

2. At the lower end of the test piece, use the positioning adhesive tape or weight respectively to fix the test piece in the specified position with the adhesive facing up. When fixing , do not make it warp or bulge. If there is a bulge in the edge part , it is necessary to fix this part on the inclined surface with another adhesive tape.

3. To keep the length of the roll-up section constant at 100 mm, adjust the center of the ball to the start of the ball according to the size of the ball.

4. Save the ball in the rust inhibitor , remove it with tweezers , and then clean the test ball cleaning method . After cleaning , place it in the starting position and allow the ball to roll off the roll section.

5. Test the cleaning of the ball, test the surface of the ball, and scrub with a solvent-stained gauze-like material. After the surface has dried , wipe it with a new clean gauze soaked in solvent until it is considered visually clean.

Note:

1 ) Fabrics such as gauze, non-woven fabrics , etc. that do not fall off when scrubbed and contain no solvent-soluble substances.

2 ) Industrial grade solvents such as naphthenes, solvent oils, alcohols, isopropanol, toluene, etc., or no residues.

6 , the viscosity tester preselected the largest steel ball:

1) adjusting the starting position, with the balls of different sizes, repeated washing ball, rolling series of operations, from the stop in the measurement period (the ball does not move up more than 5s) various balls to remove the largest.

2) the test sheet was found out the same maximum number of balls and ball size of two adjacent balls, each of one test on the same sample, to confirm the maximum ball ball number.

3) Prior to single out the biggest balls on the same test piece are rolling several times, but it can not serve as the official test data processing.

7 , formal test

1 ) Take three specimens and perform a ball test with the largest ball number.

2 ) If a sample fails to stick to the ball , it can be replaced with a ball whose ball number is smaller than its one test . If it still does not stick , it must be retested according to 7.2.6 to 7.2.7 .

8 , viscometer test results

The test result is expressed as the median (ball number) of the steel ball number of the results of the three test ball rolling tests at the time of the official test.

How to operate the sticky tape testing machine? After analyzing the operation steps of the sticky tape testing machine of the above eight points , we believe that our customers have a deeper understanding of the sticky tape testing machine .
