How much do you know about PTFE base tape membrane? Today, the editor will take you into the company to learn more about this material. Let’s take a look below.
Medical membrane materials are often divided into two categories: artificial kidneys and artificial lungs.
The membrane materials for artificial kidneys mainly include cuprammonium regenerated cellulose, saponified cellulose acetate, cellulose acetate, polyacrylonitrile, polymethylmethacrylate, ethylene-vinyl alcohol copolymer, polycarbonate, and polysulfone. , as well as polyethylene, polypropylene, etc.
The membrane material for artificial lungs is mainly silicone rubber, which has good oxygen and carbon dioxide permeability, but its breaking strength is low.
The mechanical strength and permeability of the silicone rubber membrane reinforced with silica, polyethylene, polyamide, and glass fiber are improved.
PTFE baseband membrane has a microporous structure with staggered fibers. It has high porosity and a pore size in the range of 0.1μm-10μm. It is a polymer filter membrane that can intercept solid particles and colloidal particles in gas or liquid.
The pore size is small and uniform, so higher efficiency can be achieved with lower resistance.
Filter elements are widely used in air purification equipment and can effectively filter dust, particles, carbon dioxide, etc. in the air.
In addition to household use, it is also used for dust protection in factories, clean workshops, operating rooms, laboratories, electronic machinery and communication equipment, etc.
