I. Introduction
As a common medical and health care product, the adhesion of plasters and patches is a key indicator to measure product quality. If the adhesion is too low, the patch will easily fall off during use, which will affect the best effect; Too high adhesion may lead to irritation and other problems. Therefore, it is of great significance to scientifically and accurately test the adhesion of plasters and patches. This article will focus on the development of methods, instruments and technologies for adhesion testing of plasters and patches.
To learn more about adhesive testing related products, pay attention to Quankeruida.
2. Test methods for adhesion of plasters and patches
At present, the adhesion test methods of plasters and patches mainly include initial adhesion test, stickiness test and peel strength test.
1.Initial tack test: The initial tack test is a measure of the adhesion of the plaster and patch at the time of initial adhesion. Commonly used methods are the inclined ball rolling method and the roller method.
2.Adhesion test: The adhesion test measures the ability of a plaster or patch to maintain adhesion over a period of time. Commonly used methods are tensile testing and stickiness testers.
3.Peel Strength Test: The peel strength test is a measure of the tensile force that a plaster or patch can withstand when peeling. Commonly used methods are electronic peel testing machines and tensile testing machines.
3. Adhesion testing instrument for plasters and patches
With the development of science and technology, a variety of adhesive and patch adhesion testing instruments have appeared on the market, mainly including initial adhesion tester, adhesive tester and electronic peel testing machine.
1.Initial tack tester: The initial tack tester uses the inclined rolling ball method or roller method to evaluate the initial adhesion of the patch through the short contact between the small pressure between the steel ball or roller and the adhesive surface of the patch sample, and the adhesion of the steel ball or roller.
2.Stickiness Tester: The stickiness tester mainly examines the ability of the patch to maintain adhesion for a certain period of time through the tensile test method or the stickiness tester.
3.Electronic Peel Tester: The Electronic Peel Tester uses the peel strength test method to measure the tensile force that the patch can withstand when peeled.
Fourth, the development of adhesion testing technology for plasters and patches
As the demand for adhesion testing of plasters and patches continues to increase, testing technology is also evolving. It is mainly manifested in the following aspects:
1.Improvement of test methods: Improve the accuracy and repeatability of the test through the improvement of existing test methods.
2.Updating of instruments and equipment: research and development of new test instruments to improve testing efficiency and accuracy.
3.Improvement of automation: Adopt automated equipment to reduce the impact of human factors on test results.
4.Data processing and analysis: With the help of computer technology, real-time collection, processing and analysis of test data are realized, providing a basis for product optimization.
V. Conclusions
Plasters and patch adhesion tests are important means to evaluate product quality and safety. Understanding adhesion testing methods, instruments, and technology developments can help provide manufacturers and regulators with reliable testing methods. In the future, with the progress of science and technology, the adhesion testing technology of plasters and patches will continue to develop to provide a stronger guarantee for product quality and safety.
