Microporous structure of ptfe composite filter paper

Times are changing, society is constantly progressing, and technology is constantly maturing. In recent years, people Many new materials have been developed, among which the PTFE composite filter paper can be described as a shining star. It has made great contributions to my country’s filtration industry.

The production of filter paper is very simple. It is nothing more than soaking a variety of fibers in a water-based binder to completely disperse them, and then forming a tight joint on the silk screen. The paper rolls are joined and dried, impregnated, and dried again to an acceptable humidity level. But in fact, manufacturing efficient filter paper and maintaining consistent performance from batch to batch, roll to roll, and even year to year requires a very narrow range of changes in its weight, porosity, air permeability, strength, etc.

PTFE composite filter paper is made from polytetrafluoroethylene (ptfe) suspended powder and is expanded and stretched to form a microporous film. ptfe high-efficiency filter paper has a fibrillar microporous structure. The porosity of the membrane can reach more than 88% or even higher. Moreover, the membrane has 1.4 billion micropores per square centimeter, with a pore diameter ranging from 0.1um to 0.5um. High-efficiency filter paper has high and low temperature resistance (-200°C to 260°C). It will not age, split, discolor, and has strong weather resistance after long-term use.

It is a ptfe composite filter paper manufacturer integrating production, sales and customization. The company has advanced PTFE 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.
