Abstract
The utility model discloses a nano - fiber composite membrane, wherein nano - fiber composite membrane includes that base cloth and parcel are in nanofiber membranes in the base cloth, its characterized in that: there is the compound hole of the ultrasonic wave that forms by ultrasonic wave composite technology on the base cloth. Compared with the prior art, the utility model discloses nano - fiber composite membrane just is formed with the compound hole of the ultrasonic wave that forms through ultrasonic machining by nanofiber membranes and compound the forming in parcel layer on the base cloth. Utilize high -frequency vibration wave propagation to need welded base cloth surface about arriving, under the pressor circumstances, make base cloth surface material looks mutual friction and form fusing between the molecular film, reach base cloth surface material's butt fusion to accomplish the welding. Its advantage lies in fast, energy -conserving, fuse that intensity height, electric conductivity are good, the sparkless, be close cold state processing.
Description
Technical field
The utility model relates to a kind of nano-fiber composite film, specifically a kind of nano-fiber composite film for water filtration, air filtration and individual protection series of products.
Background technology
Nano fibrous membrane refers to the fibrous film with continuous poriferous structure with nanoscale, and this film usually can by unordered or have the nanofibres deposit necessarily put in order and form.Because nanofiber diameter is less, there is larger specific area, thus can produce some special physicochemical properties as dimensional effect, molecule be redirected and other novel matter as dimensional contraction etc.Nano fibrous membrane is a kind of novel nano material, may be used for the structure or the element that design and build nanoscale.Along with the develop rapidly of nanosecond science and technology, nano fibrous membrane more and more receives the concern of people.
Prepare nanofiber and nano fibrous membrane can by descending or ascending method, this depends on final size and dimension.A kind of front method main body is constantly cut down until target size, and then a kind of method is then as played with building blocks, and atom or molecule are progressively built into nanostructured.The preparation method of nanofiber is a lot, as pulling method, and template, phase separation method, self-assembly method, method of electrostatic spinning and bubble electrospinning process, but, will prepare the nano fibrous membrane with continuous structure in enormous quantities, bubble electrospinning process is the most efficient the most direct method.
