Professional Manufacturer Last Adhesion Tape Retentiveness Tester Adhesive Tapes shear
Apply to under the continuous heating conditions,Measured parallel to the direction of a certain weight under pressure sensitive adhesive tape adhesive ability.Shear strength (resistance to shear force) is the adhesive tape as the base material used in the same plane when the ability of resistance to static force.
The significance of the application:Shear failure temperature refers to when the sample is load weight, its temperature bonding shear failure of the region.
Overview of the test test method
Solution according to control the speed of a tape is paste in the standard of sheet metal.The steel plate installed in a vertical adjustable heating furnace, and then put a standard quality weight hanging on the free end of the tape.The temperature of the heating furnace to control good speed stability, and determination of shear failure.
Temperature control range:Normal~300℃
Control methods:Microcomputer P.L.D automatic temperature control algorithms.
Temperature resolution:0.1℃ unit showing.
Control accuracy:±0.3 ℃.
Distribution of precision:±1%(200℃).
Electric control: specimen harmlessly, buzzer rang (with switch), and automatically break hot
Manufacturing material: internal SUS# 304 stainless steel plate, external: paint coating.
When counting device: electronic LCD display, automatic retention time, 99999.9 hours (or minute) can be set
Weight and size:80kg 140×55×85 cm
Power:1Ø, AC 220V/50Hz
Program set the initial heating furnace temperature of 40 ℃, can preheat furnace to the temperature.
Will spray a solvent on the test panel, absorb good clean materials used to wipe dry.Repeat this solvent cleaning three times.Finally using MEK or acetone to wipe.Test panel before use must maintain at least 10 minutes in this condition.Less than ten minutes of panel should be cleaned.
Samples in the middle of the test at the end of the panel, without any pressure to 24 x 24 mm tape precise coverage area.
In order to prevent the solution volume to cutting on the edge of the test plate samples, need to be at the free end of the sample is placed under another same thickness or slightly thin panel, in the solution volume before contact with the edge of the panel.With 600 + / - 20 mm/min) signals.a detection rate in the extension direction of the area two times.
Put the fixture in the sample free end of the cover, make sure fixture full open on the width of the sample, the uniform load distribution.
Pensile clog, allow 2 minutes to 30 + / - wetting time (stay).
On the test detection device, make the free end of the vertical test samples, make sure there are no stripping force on the samples.
Gently apply load or other agreed load (500 g) on the jig, lest cause sudden impact on tape samples.According to tape the cohesive strength, choose suitable tape load, such as for traditional styrene block copolymer (SBC) pressure sensitive adhesive, selection of load is 500 g, with strong adhesive, such as acrylic pressure sensitive adhesive, selection of load is 1000 g.If the type of adhesive is unknown, the first to use 500 g load.If the tape SAFT is greater than 205 ℃, can increase the applied loads, on the other hand if SAFT is less than 40 ℃, can reduce the applied loads.Applied load as quickly as possible to avoid heat loss, but be careful, don't have sudden impact on tape samples.
Resets the timer.
Close the oven door, start the timer.Note: once the oven door closed, during the test are not allowed to open again.
