The waterproof and breathable principle of PTFE bubble point membrane: In the state of water vapor, water particles are very small. According to the principle of capillary movement, they can smoothly penetrate into the capillary tube to the other side, thus causing breathability.
When water vapor condenses into water droplets, the particles become larger. Due to the surface tension of the water droplets (the water molecules “pull and compete” with each other), the water molecules cannot smoothly break away from the water droplets and penetrate to the other side. It is to prevent water penetration and make the bubble point membrane waterproof.
?PTFE bubble point membrane has much higher production process requirements than ordinary waterproof materials; at the same time, from a quality point of view, bubble point membrane also has functional characteristics that other waterproof materials do not have.
Widely used in urban watercourse treatment, various wastewater treatment, etc., generally using ultrafiltration membranes and microfiltration membranes.
In industry, it can be used in dairy manufacturing, semiconductor manufacturing, food manufacturing, paper manufacturing and pharmaceutical manufacturing.
