Source: Sanquan Zhongshi headquarters editor: Sanquan Zhongshi news department August 15, 2017 how to detect the peel strength of plaster? How to test the peel strength of plaster with blj-c is described in detail in this paper The 180 ° peel tester blj-c has two test modes: fixed-point peel strength test and peel strength test It is suitable for peel strength test of all kinds of plasters It is the ideal choice for producing gel paste, rubber paste, Babu paste, Babu agent and plaster Key words: 180 degree peeling test machine, Babu agent 180 degree peeling test machine, gel paste 180 degree peel test machine, rubber paste 180 degree stripping test machine, Babu paste 180 degree peel test machine The plaster of 180 ° peel testing machine needs to stick to a certain part of human body for a long time in the use process, and the patch should be replaced timely according to the doctor's requirements after a period of use, so as to better recover the patient People often feel uncomfortable when removing the plaster in use Some plasters have too strong adhesion, which can cause pain Therefore, manufacturers are also very concerned about this performance In the industry, this performance is called peel strength How to detect the peel strength of plaster? In the national pharmacopoeia 2015 edition, the adhesion determination method also has clear provisions 180 ° peel tester produced by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd Blj-c is an instrument developed in accordance with the Pharmacopoeia of the people's Republic of China (2015 Edition) and YY / t0148 standard, which is applicable to the performance test of adhesive, adhesive tape, self-adhesive, medical paste, protective film, release paper, composite film, film, paper and other related products, such as peeling, breaking and so on The 180 ° peel tester blj-c has two test modes: fixed-point peel strength test and peel strength test How to test the peel strength of plaster with blj-c 180 ° peel tester? Here is a brief introduction of the specific steps: before the test, the preparation before the test should be carried out: First, clean the test board: wipe the test board with the wiping cloth and the wiping agent, then dry it carefully with the clean gauze, and repeat the operation several times until the working surface of the test board is clean After wiping, do not touch the working surface of the plate with hands or other objects Then sampling and sample preparation: take clean plaster of more than 200 mm, and the bonding surface of plaster shall not touch hands or other substances The plaster was bonded to the cleaned test plate Then roll the sample back and forth three times with the pressure roller at the speed of about 300 mm / min under the self weight (no bubble is allowed at the bonding part between the sample and the test plate) After the sample is prepared, it shall be stored in the test environment for 20-40 minutes before the test Specific test steps: 1 Turn on the power, turn on the power switch, enter the welcome interface, wait for 20 seconds or press the [reset] key to enter the test interface; 2 Press the [return] key to return the fixture to its original position, and press the [set] key to enter the parameter setting interface 3、 Press the [Select] key to select the items to be modified, set the test parameters to the required test values, press the [OK] key to save after each setting is completed, and then press the [reset] key to return to the test interface; fourthly, fold the free end of the sample 180 ° in half, and peel off the bonding surface from the test plate about 25 mm Fix the free end of the sample and the test plate on the fixture respectively, and keep the peeling surface consistent with the force line of the testing machine; 5 Press the [clear] key to clear the parameters, and press the [test] key to start the test; 6 Press the [OK] key to print out the test results after the test Conclusion: according to the test steps explained by Xiaobian, you can easily solve the problem of how to detect the peel strength of plaster The 180 ° stripping tester blj-c designed and developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd adopts a horizontal structure, which can solve the problem that the sensor value is not affected by the weight of the fixture And equipped with a printer, can output data quickly, convenient for users to save data It is the ideal choice for producing gel paste, rubber paste, Babu paste, Babu agent and plaster.
