Properties and stability of polytetrafluoroethylene
1. Stable at room temperature and pressure, avoiding moisture, heat, and high temperatures without a true melting point. It slowly decomposes above 450 ℃ and directly becomes a gas. At 327 ℃, the mechanical strength suddenly disappears. Insoluble in any solvent. Apart from being able to react with Date: 2024-08-01 -
Microporous filtration membrane penetrates substances
The intercepted substances are mainly proteins, various types of □, bacteria, viruses, latex, particles, with a filtration accuracy of 10-4cm~10-7cm. Different pore sizes of ultrafiltration membranes are used to separate liquids, with a molecular cutting weight (CWCO) generally ranging from 60 to 5 Date: 2024-08-01 -
Performance of microporous filtration membrane
The performance profile of microporous filtration membranes is as follows: CA (cellulose acetate) is suitable for aqueous solutions and has low protein adsorption; Nylon (nylon) is suitable for aqueous solutions and various organic solvents, with low solubility, protein adsorption, and sterilization Date: 2024-08-01 -
The process of waterproof membrane
The material of the anti fouling film is mainly fluoride, and there are two processing methods: soaking method and vacuum coating, with the most commonly used method being vacuum coating. After the anti reflective film layer is completed, fluoride can be deposited onto the reflective film using an e Date: 2024-08-01 -
Classification and Application of PTFE Membrane
1. PTFE clothing filmA microporous film made by biaxial stretching method using the pore forming characteristics of polytetrafluoroethylene plastic resin. The surface of the membrane can reach over one billion micropores per square centimeter, with each pore diameter (0.1 μ m-0.5 μ m) several hund Date: 2024-08-01 -
The main structure of PTFE membrane
PTFE membrane is a microporous film produced by special processes such as pre mixing, extrusion, rolling, and biaxial stretching using polytetrafluoroethylene dispersed resin. It is divided into clothing membrane, PU micro waterproof membrane, filtration membrane, and purification membrane.Main stru Date: 2024-08-01
