    The foldable polypropylene composite cover is an important part of the plastic infusion container, which consists of three parts: the foldable outer cover, the inner cover and the gasket As a new type of bottle cap for infusion bag, it has been widely used in clinic It is also necessary to test the breaking force of the foldable polypropylene composite cover Because its breaking force is too large or too small, it will have an impact on the quality of the pharmaceutical industry If it is too large, it is easy to produce debris during the use of puncture The debris may be quickly incorporated into the liquid medicine, which will pollute the liquid medicine and pose a health threat to the patients On the contrary, it may lead to poor sealing, which will also pollute the liquid medicine Therefore, the fracture strength index of the foldable polypropylene composite cover can be controlled within a reasonable range to ensure the quality of the internal liquid medicine Taking the zdy-02 breaking force tester independently developed by Jinan Saicheng as an example, this paper conducts a special test on the breaking force of the foldable polypropylene composite cover produced by a manufacturer Through the detailed record of the test process, test results and other data, it provides a reference direction and method for the majority of enterprises in need Objective: foldable polypropylene composite cover is a new product in recent years, which is widely used in plastic infusion containers As the product is a new invention of a medical packaging material company in Hunan Province, there is no specific national standard Based on the standards of polypropylene combination cover (ybb00242004) and neutral borosilicate glass ampoule (ybb00322002) for plastic infusion containers, the company has written the industry standard according to the format of Chinese Pharmacopoeia 2 The executive standard is not available in the country, so the enterprise standard of the enterprise applying for the product shall be implemented Test sample: the foldable polypropylene composite cover (Note: the sample is provided by the customer of Jinan Saicheng) test equipment "zdy-02 breaking force tester" independently developed by Jinan Saicheng has met a number of national and international standards: gb2637-1995, ybb00332002-2015, ybb00322005-2015 5 Test process (1) 10 samples were sterilized at 121 ℃ for 30 minutes (after cooling to room temperature) (2) It is fixed on the fixture of the pull type combined cover breaking force tester, and the vertical force is applied at the breaking point of the easily folded cap at the speed of 200 mm / min (3) Record the test data (4) According to this method, 10 samples are tested one by one 6 The breaking force of test results shall not exceed 80N 7 Conclusion "zdy-02 breaking force tester" Through the use of imported sensors, the accuracy of the data is greatly improved in the test of the sample of the foldable polypropylene composite cover submitted by the manufacturer, which has the advantages of convenient operation, higher efficiency, humanized design of the fixture, data output and printing, greatly facilitates the operation of the user and the analysis of the results It is a special model worthy of selection and trust for the major pharmaceutical manufacturers High precision instruments.
