Design and manufacture the products according to the provisions of GB4852, initial viscosity test is suitable for various adhesive products, such as adhesive tape, medical patch, self-adhesive labels, protective film etc.
Adhesive tape initial adhesion testing machine is mainly composed of inclined plate, ball release, bracket, adjustable horizontal base and steel ball and so on. The inclined ball method, through the ball and the pressure-sensitive adhesive tape sample viscosity surface with small pressure between brief contact occurs, adhesive tape adhesion of steel ball tack sample to test. The specific method of operation is to stick up, placed in the plate tilt test was 30 degrees, the maximum number of balls from the ball, in order to free, record up to 5 seconds or more can stick the ball in the sample no..
