An electrolyte membrane, also known as an ion exchange membrane, is a semipermeable membrane that conducts certain ions while blocking other ions or substances of different charge, such as an electrol

Endotoxin is a heat-stable toxic substance that can usually withstand commonly used sterilization temperatures, such as dry heat or autoclaving, and can withstand temperatures up to 250°C for a short

Modified positively charged filter membrane refers to a filter membrane with a positive charge after chemical modification. The introduction of positive charges on the membrane surface can

The ASTM F83 test mentioned here should be ASTM F83-15a related to the filter membrane. ASTM F838-15a is a standard test

The double-layer gradient structure of microporous membranes refers to two layers of membranes with different pore sizes, usually arranged such that the layer with larger pore size

What is the "fiber-free release" standard of microporous filtration membrane? It refers to the phenomenon of fiber shedding on the surface of the membrane caused by factors such as material, productio

Medical sterile filtration is usually performed using filter membranes made of polyethersulfone (PES), polyvinylidene fluoride (PVDF) or nylon. A prominent factor in the selection of these membrane ma

When we use microporous filtration membranes, there are several important factors that must be considered. This is mainly to ensure its correct and effective use.

The field of microporous membranes used in the air filtration industry is also particularly extensive. Microporous membranes are used to remove particles, impurities, and dirt (including bacteria, vir

Cellulose acetate membrane is a synthetic membrane used in a wide variety of applications, including water filtration, gas separation, and dialysis. It is extracted from cellulose

Diffusion test, also known as diffusion flow test, is a common method for evaluating the performance of microporous filtration membranes.

Regenerated cellulose (RC) membranes are produced from pure cellulose or cellulose derivatives. Cellulose is usually derived from wood pulp or cotton linters, and is named after a certain process

Polyvinylidene fluoride (PVDF) is a highly non-reactive pure thermoplastic fluoropolymer. PVDF is a chain of carbon atoms with two fluorine atoms and two hydrogen atoms attached to each carbon.

How to choose the right microporous membrane? The first task is to have a comprehensive, in-depth and clear understanding of the substances that need to be filtered. Taking liquids as an example, the

PAN has a linear structure and the repeating unit is -CH2-CH(CN)-. Since the carbon-carbon bond on the polymer main chain is a single bond, the chain is flexible and can move to a certain extent

The author recently saw a video on a platform about the analysis of the causes of spontaneous combustion or spontaneous combustion and explosion of electric vehicles.

In medical infusion sets, the filter membrane is a key component to prevent particles, air bubbles and bacteria from entering the patient's blood.

In the field of high-precision filtration, it is a very important technical work to select a suitable microporous filtration membrane.

PA stands for polyamide, which is a polymer with amide bonds in its molecular structure. PA6 and PA66 are two specific types of polyamides commonly used in the production of nylon filter membranes.

Polyethersulfone (PES) is a polymer commonly used in filtration applications, especially to make membranes for microfiltration, ultrafiltration and reverse osmosis processes.
