Microporous membranes cannot be used to separate ions and small molecules. Due to the following main reasons, here is a summary and sharing

Speaking of the waterproof and breathable principle of microporous membrane, we can look at it from a molecular perspective, by considering the structure of the membrane material and the interaction b

To discuss the hydrophobicity of microporous membranes, we must first know the concept of hydrophobicity. The so-called hydrophobicity is a term used to describe the physical properties of substances

Aqueous phase filtration membrane is one of the most commonly used membrane materials. A more serious problem is that the membrane dissolves during the filtration process. Since the membrane dissolves

We can use water-based membranes to filter organic reagents. This question requires us to first understand the definitions of two types of membranes. The so-called water-based membranes refer to some

If we look at it from a molecular level, to ensure the effective separation of colloidal particles during the filtration process, we must first have a correct understanding of the colloidal particles.

What is glass fiber filter membrane? It is a filter medium made of fine glass fibers, composed of borosilicate glass fibers that are tightly woven or bonded together to form a porous structure. It is

Separating and retaining microorganisms from various solutions is very important for the selection of filtration membranes. Different microorganisms have different requirements for the type of membran

In this article, we will focus on reusable microporous membranes. What factors affect its use? In summary, it is mainly the type of filter membrane, the nature of the filtration process, and the effec

Whether microporous membranes can be reused depends largely on the material composition, material structure and characteristics of the filtration or separation process involved in the membrane. In act

Does the microporous membrane have to be soaked before use? This question should be discussed from two aspects. Some membranes do not need to be soaked before use, such as PES (polyethersulfone) micro

Do filter membranes have a front and back side? We need to talk about it from two aspects. One is pure membranes and the other is composite membranes. Generally speaking, pure membranes usually have n

Air permeability and water pressure resistance of microporous membrane are one of the key factors reflecting its application performance. Generally, when the air permeability of microporous membrane i

Membrane filtration and membrane concentration are two different processes. They both use membranes to separate and control particle molecules. When it comes to their different treatments

In the production of composite membranes, the porosity or other indicators of each batch often vary greatly. The reason for this should be a more complicated problem, because the situations that occur

Polyaramid is a class of synthetic polymer materials known for its high strength, heat resistance and flame retardancy. Its most prominent feature is its unique molecular structure, which is polymeriz

Polyimide film is widely used in the electronics and aerospace industries due to its unique combination of properties. It is very suitable for various electronic components and equipment, as well as v

Polyimide is an aromatic heterocyclic polymer compound containing imide chain segments in its molecular structure. It is a very high-quality base membrane material in the membrane manufacturing indust

Polyimide filtration membrane refers to a membrane made of polyimide, because polyimide is a high-performance polymer with excellent thermal stability,

When we measure microporous filtration membranes, we usually use several main tools, such as optical microscopes, scanning electron microscopes (SEM) and transmission electron microscopes (TEM),
