With the rapid development of my country’s economy, water shortage has become a limiting factor restricting the further development of my 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. The filter membrane channel can be regarded as a capillary tube. Capillary action causes the liquid soaked in the capillary tube to flow out of the hole; when the upstream pressure increases, the upstream gas dissolves. In the wetting fluid, since the downstream is at normal pressure, which is lower than the upstream pressure, 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 laminated 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.
