Microporous filtration membranes are based on the principle of size separation and are more commonly used in the detection of pathogenic microorganisms and microbial contamination detection industries

The filtration efficiency test of air filter membranes usually uses various standardized methods and techniques, including particle counting method, gravimetric method, photometric method, scanning el

The working principle of gas separation membranes is determined by factors such as the size, shape, polarity and chemical interaction of gas molecules. These characteristics determine the speed at whi

The air contains a variety of molecules and particles, both natural and man-made. In addition to the parts that can be used, it also contains components that affect its use and even are harmful.

As the name suggests, "click chemistry" refers to fast, reliable, and high-yield chemical reactions. It is a concept first proposed by Professor K. Barry Sharpless in 2001. It refers to the use of spe

Microcellulose filter membranes play an important role in the separation, purification and concentration of biologically functional proteins. These filter membranes, which are composed of countless sm

PC (polycarbonate) and PET (polyethylene terephthalate) are the two most commonly used materials for track etching films. They both have good etching track properties, but there are also some qualitat

There are many types of materials used in the production of track etching films, such as polycarbonate (PC), polyethylene terephthalate (PET), polyimide (PI), polypropylene (PP), polystyrene (PS), pol

The porosity of the membrane plays a vital role in the filtration process. The porosity mentioned here refers to the hollow space or the volume fraction of the voids in the membrane material. I

Silanization method is a commonly used surface modification technology for filter membranes. It is a chemical reaction between the surface substance of the filter membrane

Under normal storage conditions, it has not experienced the effects of high and low temperatures, but the filter membrane membrane deformed and shrunk seriously after being cut. What is the reason for

The pollution of the filter membrane refers to the accumulation of substances on the surface of the filter membrane or inside the pores, which leads to a reduction in filtration efficiency and affects

Membranes used to filter pharmaceutical solutions require specific characteristics to ensure effective and safe filtration. The following is an analysis of the main characteristics

Spin coating and dip coating are two common techniques for applying thin films or coatings to substrates. The purpose is to apply the function of surface coating to optimize and upgrade the properties

Chemical vapor deposition (CVD) is a widely used technology for depositing thin films or coatings on substrates (including filter membranes).

The sol-gel process for filter membrane modification is a technology in surface coating. It mainly uses sol (colloidal suspension of solid particles in a liquid) through chemical reactions such as hyd

Layer-by-layer (LbL) assembly is a widely used technology to modify the surface properties of filter membranes by depositing alternating layers of different materials onto the membrane surface.

Polytetrafluoroethylene (PTFE) is hydrophobic in nature, meaning it repels water. This property is attributed to the structure of PTFE, which is composed of carbon atoms completely surrounded by fluor

Graft polymerization and plasma-induced grafting are two technologies used to modify the surface properties of materials.

Polyethersulfone (PES) and nylon (NYLON) are both commonly used filter membrane materials. PES is a synthetic polymer composed of repeating units of ethylene
