Plasma treatment is a surface modification technology for filter membranes, and its main function is to enhance the performance of the filter membrane.
The pressure drop test of the air filter membrane is mainly to evaluate the air flow resistance through the filter membrane. The test data provides data and reference for the filter performance and it
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
