    Plaster, the term paste, is a kind of medical preparation commonly used in clinical medicine to assist the treatment of rheumatism and iron injury, which plays an important role in the field of clinical medicine It is easy to use, so that people will also be at home in daily life Therefore, the adhesive force of plaster plays an important role in patients, so what physical indicators should be tested for plaster? For this reason, the national pharmacopoeia has made detailed requirements on the adhesion test of plaster, among which the three major indexes of initial adhesion, adhesion and peel strength are the provisions of the pharmacopoeia for plaster! Based on the in-depth study of the national pharmacopoeia, Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd has designed and developed three instruments, namely, the cny-1 initial viscosity tester, the cny-2 holding viscosity tester and the blj-c 180 ° peel tester, to test the three physical properties of the plaster, namely, the initial viscosity, the holding viscosity and the peel strength 1 The initial viscosity of the plaster is measured by using the cny-1 initial viscosity tester developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd The cny-1 initial adhesion tester is suitable for the initial adhesion test of all kinds of pastes, pastes and medical tapes Test principle of cny-1 initial viscosity tester: the inclined rolling ball method is used to test the initial viscosity of the sample by the adhesion force of the product to the steel ball when the steel ball and the viscosity surface of the test sample contact briefly under small pressure     Test method: first, adjust the inclined plate of the initial adhesive tester to 30 degrees with the horizontal surface, fix the adhesive surface of the plaster sample on the inclined plate of the initial adhesive tester, place a stainless steel ball in the steel ball placement area on the inclined plate and adjust the initial position, release the steel ball, roll it and pass through the adhesive surface, according to the Zui big ball steel ball that the adhesive surface of the plaster can stick, The initial viscosity was evaluated 2 Determination of the adhesive property of the plaster The cny-2 adhesive property tester developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd is specially designed for the adhesive property test of the plaster It is applicable to the adhesive test of paste products required by Chinese Pharmacopoeia Test principle of cny-2 adhesion tester: hang the test plate with specimen vertically on the test stand, hang the weight of specified weight at the lower end, and use the displacement of specimen adhesion after a certain time, or the time of specimen complete separation to characterize the ability of adhesive tape to resist pull off Technical features: 1 The test board and test weight designed in strict accordance with the pharmacopoeia standard ensure the accuracy of the test data 2 Three test stations are designed, economical and practical 3 Automatic timing, end reminder and other functions further ensure the high performance of the test results 4 The system is controlled by microcomputer, with PVC operation panel 3、 Determination of plaster peel strength blj-c180 ° peel tester It is an instrument developed by Jinan Sanquan Zhongshi Experimental Instrument Co., Ltd according to the Pharmacopoeia of the people's Republic of China (2015 Edition) and YY / t0148 standard, which is applicable to the peel and pull-off performance test of adhesive, adhesive tape, self-adhesive, medical paste, protective film, release paper, composite film, film, paper and other related products Blj-c180 ° peel tester has two test modes: fixed-point peel strength test and peel strength test Blj-c180 ° peel testing machine can prove that the plaster has excellent physical properties by testing the initial adhesion, adhesion and peel strength!
