Friction coefficient peel tester to detect the release force of double-sided adhesive tape and release paper

Release paper, also known as silicone oil paper, anti stick paper It is mainly used to isolate sticky objects, such as adhesive tape Generally, it needs to be peeled and discarded in use; now it is widely used, mainly for tape / label or carrier of rubber products There are also many applications in food, medical and health industries In the process of die-cutting, we often encounter the problem that the double-sided adhesive and release paper can not be separated, which easily leads to the scrap of double-sided adhesive and unnecessary waste, and why the double-sided adhesive and release paper can not be separated? The fpt-03 friction coefficient stripping tester of Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd can be used to solve the problem that the double-sided adhesive tape and release paper cannot be separated The following three springs in the small stone on the simple introduction of fpt-03 friction coefficient peel tester to detect the release force of double-sided adhesive and release paper Fpt-03 coefficient of friction stripping tester fpt-03 coefficient of friction stripping tester, the double-sided adhesive and the release paper sample glue are faced with the standard test board, rolled three times with the standard press roller, clamped on the stripping tester, and the sample and the test board are stripped in the form of 180 ° The force value sensor records the force value during the stripping process, and the average force value divided by the sample width is the stripping strength The instrument has the dual test functions of friction coefficient and 180 ° peel strength, that is to say, it can meet the test of static friction coefficient and dynamic friction coefficient by various national and international standard methods, as well as the test of small force peel strength of various adhesive composite products, medical paste, release paper, protective film, mobile phone touch screen and other products Reference standard: GB / T 2792-1998 standard is applicable to the determination of 180 ° peel strength of single and double-sided pressure-sensitive adhesive tape and stainless steel plate, as well as other materials, such as PVC, ABS, PE, etc Test steps: 1 Wipe the test board with cleaning agent, then dry it with clean degreasing gauze, and wash it repeatedly for more than three times until the working surface of the board is clean through visual inspection After cleaning, do not touch the working surface of the board with hands and other objects 2 measure the width of the tape with an accuracy of not less than 0.05mm 3 before preparing the sample, first tear off the outer 3-5 layers of adhesive tape, and then take more than 200 mm of adhesive tape (the adhesive surface of adhesive tape shall not touch hands or other substances) The adhesive tape shall be bonded to the cleaned test plate Place a polyester film or other material about 200 mm long and 40 mm wide under the other end of the test plate, and then roll the sample back and forth at a speed of about 300 mm / min with the pressure roller under the self weight for three times (no bubbles are allowed at the bonding place between the sample and the test plate) 4 after sample preparation, the test shall be carried out after 20-40min storage in the test environment 5 fold the free end of the sample in half 180 ° and peel off the bonding surface 25 mm from the test plate Clamp the free end of the sample and the test plate on the upper and lower retainers respectively The peeling surface shall be consistent with the force line of the testing machine The tester peels continuously at a falling speed of 300 mm / min ± 10 mm / min, and has an automatic recorder to draw the peeling curve 6 when the double-sided pressure-sensitive adhesive tape is bonded with stainless steel plate or other materials, first tear off 3-5 layers of the outer side of the double-sided adhesive tape, then take more than 200 mm adhesive tape and stick it on the polyester film, then peel off the other side of the isolation paper and conduct the test according to the provisions of 7.3, 7.4 and 7.5 7 when determining the peel strength of single-sided pressure-sensitive adhesive tape or double-sided pressure-sensitive adhesive tape and sheet, film and other materials, first stick the sheet, film and other materials on the steel plate, and then conduct the test according to the provisions of 3, 4 and 5 Experimental results: let's see that the normal temperature release force is the release force data obtained by the standard test method under the normal temperature, the unit is n / 25mm, which can be converted into g / 25mm Generally, 0.10n/25mm, i.e the peeling force below 10g, is commonly known as light peeling; o.20n/25mm, i.e the peeling force below 20g, i.e medium peeling; 0.35-0.45n/25mm, i.e the peeling force between 35-45g, i.e heavy peeling; 0.6o-0.80n/25ram, i.e the peeling force between 6o-80g, i.e heavy peeling; Of course, there are also 0.03-0.04n/25mm, that is, 3-4g peeling force, commonly known as light peeling; there are also 1.00n/25mm, that is, more than 100g peeling force, commonly known as overweight peeling Conclusion: in order to solve the problem that double-sided adhesive and release paper cannot be separated and reduce unnecessary waste, it is necessary to find out the reasons from the raw materials Release paper is unstable, paper density is not good, coating is not uniform, its penetration resistance is poor, and the adhesive penetration in release paper can not be peeled off naturally In the process of die-cutting, some products are easy to be brought up in the process of waste discharge, which shows that the stripping force is too light, so it is necessary to select a slightly heavier one If it can't be peeled or deformed due to bad peeling, it means that the parting force is too heavy, and the paper with lighter parting force needs to be selected! Therefore, mastering the release force of release paper is also an essential project What instrument is used in the stripping experiment of double-sided adhesive tape and release paper? Fpt-03 friction coefficient stripping tester of Sanquan Zhongshi can be used to test the parting force of double-sided adhesive tape and parting paper For details, please call Sales Department of Zhongshi, Sanquan.
