Fabrics Q&A

The filtration efficiency of ptfe mask filter material for bacteria and PM2.5 particles in the air can reach more than 95%, reaching the filtration standard of KN95 masks. The extremely high porosity and ultra-…

The interaction forces such as hydrogen bonds, van der Waals forces, and charge adsorption between PTFE sterilization filter membranes of different materials and different compounds to be filtered are different…

Imported spunbond filament non-woven fabric is a fabric that does not require spinning and weaving. It just arranges short textile fibers or filaments in a directional or random manner to form a fiber mesh stru…

PTFE sterilizing filtration membrane microporous filtration is mainly used to separate macromolecules, colloidal particles, proteins and other particles. Their separation mechanism is based on the physical and …

In drug analysis and dissolution experiments, filter membrane adsorption is the most common drawback of using microporous filter membranes. There are many factors that affect the adsorption of ptfe sterilizing …

Microporous membrane membrane operations include dead-end filtration (vertical flow filtration) and cross-flow filtration (tangential flow filtration). Dead-end filtration is mainly used for fluids with small s…

The membrane separation process is a method of separating mixtures using membranes. As a selective passing phase between two phases, the membrane can allow one or more components of the two phases to pass throu…

When developing analytical methods such as dissolution experiments and content of preparation samples, due to the influence of excipients, filtration is required and the continued filtrate is used as the test s…

The comfort level of wearing a mask is mainly determined by the breathability and moisture permeability of the mask. The ptfe nano mask filter membrane has higher air permeability due to its material characteri…
