The easy-folding polypropylene composite cover is an important component of the plastic infusion container, and is composed of a foldable outer cover, an inner cover and a gasket. As a novel infusion bag cap, it is currently rapidly gaining popularity in the clinic. Among them, the test of the breaking force of the foldable polypropylene composite cover is also necessary and necessary. Because the breaking force is too large or too small, it will have an impact on the quality of the pharmaceutical industry. Too large, it is easy to produce debris when puncture is used, and the debris may be quickly incorporated into the liquid, which may cause health risks to the patient; on the contrary, it may result in poor sealing and contamination of the liquid. . Therefore, the breaking force index of the foldable polypropylene composite cover is controlled within a reasonable range to ensure the quality of the internal liquid medicine. In this paper, the ZDY-02 breaking force tester independently developed by Jinan Saicheng is used as an example to carry out special tests on the breaking force of a foldable polypropylene composite cover produced by a certain manufacturer, and pass the test process and test results. Detailed records, thus providing a reference direction and method for the majority of enterprises in need. The easy-fold polypropylene composite cover is a product emerging in the market in recent years and is widely used in plastic infusion containers. Since the product is a newly invented patented product of a pharmaceutical packaging material company in Hunan, there is no specific standard in the country. The company refers to the polypropylene composite cover for plastic infusion containers (YBB00242004), neutral borosilicate glass ampoule (YBB00322002), etc. On the basis of standards, it has been written as an industry standard in accordance with the Chinese Pharmacopoeia format. 2 , the implementation of standards The country does not have this standard, so the company's corporate standards for the application for the product patent are enforced. Foldable polypropylene composite cover produced by a certain manufacturer ( Note: This sample is provided by customers of Jinan Saicheng ) The “ ZDY-02 Breaking Force Tester †independently developed by Jinan Saicheng has now met many national and international standards: GB2637-1995, YBB00332002-2015, YBB00322005-2015. 5 , the testing process (1) Take 10 samples and sterilize them by warm sterilization at 121 ° C for 30 minutes (after cooling to room temperature). (2) Fix it on the clamp of the folding type combination cover breaking force tester , and apply the vertical force to the break of the easy-folding cap at a speed of 200 mm/min. (3) Record its test data. (4) According to this method, 10 samples were tested one by one. 6 , test results Breaking force must not exceed 80N 7 , conclusion " ZDY-02 Breaking Force Tester " By using the imported sensor, the accuracy of the data is greatly improved in the test of the easy-folding polypropylene composite cover sample which is sent to the manufacturer for inspection, and the operation is convenient and efficient. The advantages of humanized design and data output printing of the fixture greatly facilitate the user's operation and analysis of the results. It is a professional high-precision and high-efficiency instrument that is worthy of choice and trust by major pharmaceutical manufacturers.
