Requirements and Methods for Physical Performance Testing of Medicinal Ointment Tubes

Ointment refers to a semi-solid external preparation with a certain consistency made by uniformly mixing a drug with a suitable base. The ointment is contained in a polyethylene/aluminum/polyethylene composite tube. In order to ensure the safety and stability of the drug during circulation and use, the drug packaging material standard sets some requirements for the physical properties of the ointment tube packaging. In the following, we will introduce the performance requirements and test methods of polyethylene/aluminum/polyethylene composite pharmaceutical ointment tubes in combination with the requirements of the national pharmaceutical packaging material standards. Reference standard (part): YBB00252005-2015 Polyethylene/aluminum/polyethylene compound medicinal ointment tube Compressive strength Take an appropriate amount of sample, tighten …

Battery Separator Testing for Lithium Batteries

Test Method

The separator is an important part of the lithium battery. The separator is electronically insulating to avoid short-circuits; at the same time, it has ion conductivity to ensure the electrochemical performance of the battery. The diaphragm has a significant impact on the capacity, cycle performance, charge-discharge rate, etc. of the battery; especially has a greater impact on the safety of the battery. Therefore, the quality of the battery separator directly affects the overall performance of the battery. We can use some measurable physical and chemical indicators and electrochemical indicators to judge the impact on battery performance. In 2018, the National Alkaline Battery Standardization Technical Committee and China Chemical and Physical …
