Background

A membrane sheet, also called a diaphragm, is a thin film that is used to separate two different environments. It can act as a barrier to prevent two different liquids or gases from mixing together. The diaphragm is made of different materials, such as polyvinyl chloride (PVC), polypropylene (PP), polytrifluoroethylene (PTFE) and the like, and is mainly characterized by high chemical inertness, corrosion resistance and good sealing property. It is commonly used to separate hydrogen and oxygen, separate different solutions, etc. in chemical production. Membrane sheets come in many different shapes and sizes to accommodate different applications and container sizes. Typically, they are round or square, and can vary in diameter and length from a few millimeters to a few meters. In addition to being used to isolate gases and liquids, diaphragm sheets may also be used in instruments such as sensors and control valves. In these applications, they may be used as conductors, allowing gas or liquid to flow through them while remaining separated.
