In order to ensure the quality of pharmaceutical PVC hard films, the ball drop impact test is undoubtedly a key detection method. Pharmaceutical PVC rigid sheets are widely used in the manufacture of a wide range of pharmaceutical packaging materials, so it is important to ensure that their quality is robust and reliable. The purpose of this paper is to improve the falling ball impact test method of pharmaceutical PVC hard sheet and its significant practical value and significance.
The principle and method of the test are elaborated.
The falling ball impact test is based on a free-fall method at a certain height, by making steel balls of different diameters violently collide with the pharmaceutical PVC hard sheet, and then systematically recording the number of fractures and the depth of penetration to show the quality of the product. This test not only accurately evaluates the resistance of pharmaceutical PVC hard films, but also provides scientific and detailed insight into their hardness, strength and toughness.
Analysis of test methods and operating procedures.
Preparatory work prior to the test.
First of all, we need to prepare for the experiment, debug the lab equipment to the best operating condition, and ensure that all instruments are in a good and stable operating environment. Next, the specifications and quantities of steel balls required for the test should be reasonably selected according to the specific needs.
The steps for making the test sample.
After selecting and determining the samples to be tested, we should cut out the test samples in strict accordance with the relevant standards and carefully mark them. At the same time, it should also be noted that the thickness of the sample must meet the minimum requirements of the national mandatory standard.
Formal testing process.
The prepared samples are placed one by one on a specific test device, and the operating accuracy of the equipment is carefully adjusted to ensure that the height of the ball and the initial position are accurate. Then, the test ball was used to smash the specimen from a high place, and the two key data of penetration depth and fracture number were closely recorded. Finally, according to the obtained experimental data, the scientific and authoritative experimental conclusions are carefully summarized and analyzed.
Application and the importance of its play.
The ball drop impact test plays an important role in the quality inspection of pharmaceutical PVC rigid tablets, so many companies and manufacturers related to the pharmaceutical industry have begun to pay attention to and actively promote this test. In particular, pharmaceutical PVC rigid tablets are widely used throughout the pharmaceutical packaging process, and they must have sufficient ability to withstand a variety of impacts and blows. The falling ball impact test can ensure the long-term durability of drug packaging and greatly improve the protective performance, so as to achieve comprehensive detection and evaluation of drug safety performance.
Summary. The ball drop impact test is a crucial method to check the quality of pharmaceutical PVC rigid tablets. Especially in the field of pharmaceutical packaging, pharmaceutical PVC rigid tablets are involved in a wide range of application scenarios. By implementing such methods for testing, it is natural to ensure that the pharmaceutical packaging used has sufficient strength and toughness to effectively protect the safety line of the drug. In addition, it can also meet the basic requirements of the relevant national mandatory standards for drug packaging.
