The protagonist we are going to introduce today is ptfe hydrophobic membrane, which is a microporous structural film formed from polytetrafluoroethylene dispersion resin after biaxial stretching. Let’s take a closer look at it. .
During the membrane separation process, the membrane acts as a two-phase separation barrier to achieve selective separation and transmembrane transport of substances under the action of transmembrane driving forces (such as temperature difference, concentration difference, potential difference, pressure difference on both sides of the membrane, etc.).
Since the American Exxon Corporation developed the first batch of industrial membranes in the 1960s, membrane technology has entered a period of rapid development.
PTFE hydrophobic membrane has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore size ranges from 0.1μm to 0.5μm.
Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
It is one of the materials with the best corrosion resistance in the world. Except for a few chemicals such as chlorine trifluoride and liquid chlorine, it is resistant to all other chemical reactions and is insoluble in strong acids, strong alkali and organic solutions. It does not change in hydrochloric acid.
The temperature resistance range is -195℃～250℃, and the long-term use temperature is -100℃～250℃.
It is a fluorine material film manufacturer integrating production, sales and customization.
The company has advanced ptfe hydrophobic membrane production lines and composite production lines.
The company’s products are widely used in various fields. With strong technical force and strict management system, the company ensures that everything focuses on the interests of users and provides users with high-tech, high-quality, high-performance, and high-level products.
