Embodiment Construction

[0012] Such as figure 1 As shown, the fluoroplastic is processed and refined to make an adsorbent dispersion, which is treated with electret technology such as electret corona method or breakdown method to make it into an electret adsorbent dispersion, which is sprayed on medical gauze. A covering film (1) is formed on the gauze, which is then processed into fluoroplastic electret medical bandages (2) of various specifications.

[0013] The fluoroplastic electret adsorbent dispersion is sprayed on medical gauze to form a covering film. When the pore diameter of the covering film is selected to be 0.1-0.5 μm, the diameter is 1 / 2000-1 / 5000 of the diameter of a water droplet, It is 700 times that of water vapor molecules, so the bandage made of this material cannot penetrate moisture in a humid environment, but it can let sweat vapor flow out smoothly, and does not gather between the body surface and the bandage, and has excellent waterproof performance .

Abstract

The invention relates to a fluoroplastic electret medical bandage which comprises a medical gauze and a cover film, wherein the cover film is formed by spraying a fluoroplastic electret adsorbent dispersion liquid on the medical gauze; and the adsorbent dispersion liquid is prepared by processing and refining fluoroplastics, is treated by an electret technology such as an electret corona method, a breakdown method or the like, is sprayed on the medical gauze to form the cover film, and is processed into electret medical bandages of different specifications. The electret medical bandage has the characteristics of bacterium resistance and inhibition, inflammation diminishing, infection prevention, dust and water prevention and good air permeability.

Description

technical field [0001] The invention provides an electret medical bandage with antibacterial and antibacterial properties, in particular to a medical bandage sprayed with a fluoroplastic electret adsorbent dispersion, which belongs to the field of medical supplies. Background technique [0002] Electret is a dielectric material that can polarize and store charges for a long time under the action of factors such as strong external electric fields for some special properties. There is an electrostatic field in the electret material formed after treatment, and the pores of the material are similar to countless passive dust-collecting electrodes. When charged particles in the air, especially submicron particles, pass through these pores, they are blocked or Capture, the neutral particles in the airflow become dipoles due to induction or polarization and are also effectively captured. Therefore, the electret material has excellent characteristics in dust prevention. [0003] Bac...
