The multi-purpose use of PTFE bubble film
With the rapid development of our country’s economy, the shortage of water resources has become a limiting factor restricting the further development of our country’s printing and dyeing industry. In order to achieve the sustainable development of the printing and dyeing industry, the recycling of printing and dyeing wastewater has become the key to achieving this goal. This requires the use of polytetrafluoroethylene bubble film.
After the filter membrane is completely wetted, pressure is applied upstream, and the filter membrane channel can be regarded as a capillary tube. Capillary action causes the liquid infiltrated in the capillary tube to flow out of the hole; when The upstream pressure increases and the upstream gas dissolves in the wetting fluid. Since the downstream is at normal pressure and is lower than the upstream pressure, the gas will overflow from the wetting fluid and form a gas diffusion phenomenon.
Polytetrafluoroethylene bubble point film Generally, polytetrafluoroethylene (ptfe) suspended powder is used as raw material, and is expanded and stretched to form a microporous film. . ptfe liquid filtration membrane has a fibrillar microporous structure with a porosity of more than 88%. There are 1.4 billion micropores per square centimeter, with a pore size range of 0.1μm-0.5μm. This membrane is coated on various fabrics and substrates using a special process. It can become a new type of filter material. The membrane has small pore size, uniform distribution and large porosity. It can filter all dust particles including bacteria while maintaining air circulation.
It is a polytetrafluoroethylene bubble film manufacturer that specializes in R&D, production and sales. The materials of the products produced by our company are all imported raw materials, with high uniformity, stable performance and good breathability. It also has high filtration efficiency and can meet the filtration efficiency level requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
