Embodiment 1

[0061] (1) Seal a layer of polypropylene polymer film coat with a thickness of 0.05mm on the surface of the zinc film material by heat sealing and curing method, and expose the edge of the zinc film material.

[0062] (2) The zinc film material after sealing is placed on the anode of the electrochemical polishing equipment, and the cathode is connected to platinum-iridium wire insoluble metals, and polished according to the following polishing parameters. The current is direct current. The current range is 1A, the voltage range is 30V, the single action time is 300s, and the polishing times are 2 times. The electrolyte used is a mixed polishing solution with a volume ratio of propanol: ethylene glycol: phosphoric acid = 50:48:2.

[0063] (3) After polishing, the product peels off the polymer film coating. As for ultrasonic cleaning in absolute ethanol, the zinc film material after the edge is sharpened can be obtained. The boundary morphology of the zinc film material and th...

Embodiment 2

[0065] (1) A layer of 0.2mm-thick polytetrafluoroethylene polymer film coating is sealed on the surface of the magnesium film material by light curing, and the edge of the magnesium film material is exposed.

[0066] (2) Place the closed magnesium film material on the anode of the electrochemical polishing equipment, connect the cathode with platinum-iridium insoluble metals, and polish according to the following polishing parameters. The current is direct current. The current range is 0.2A, the voltage range is 10V, the single action time is 20s, and the polishing times are 6 times. The electrolyte used is a mixed polishing solution with a volume ratio of ethanol:glycerol:acetic acid=55:40:5.

[0067] (3) After polishing, the product peels off the polymer film coating, and ultrasonic cleaning in absolute ethanol can obtain the magnesium film material after the edge is sharpened. The boundary morphology of the magnesium film material and the magnesium film material after edg...

Embodiment 3

[0069] (1) Seal a layer of 0.1mm thick polymethyl methacrylate polymer film coating on the surface of the iron film material by heat-sealing and curing method, and expose the edge of the iron film material.

[0070] (2) The iron film material after sealing is placed on the anode of the electrochemical polishing equipment, and the cathode is connected to platinum-iridium wire insoluble metals, and polished according to the following polishing parameters. The current is direct current. The current range is 2A, the voltage range is 60V, the single action time is 200s, and the polishing times are 5 times. The electrolyte used is a mixed polishing liquid with a volume ratio of amyl alcohol: ethylene glycol: carbonic acid = 30:60:10.

[0071] (3) After polishing, the product peels off the polymer film coating. As for ultrasonic cleaning in absolute ethanol, the iron film material after the edge is sharpened can be obtained. The boundary morphology of the iron film material and the...

Abstract

The invention discloses an edge polishing method of a metal film, the metal film and application. The edge polishing method of the metal film material comprises the following steps that a protective film with an insulating property is arranged on the metal film material, and the protective film covers the area outside the edge of the metal film material; carrying out electrochemical polishing on the metal film provided with the protective film; and removing the protective film of the polished metal film. According to the edge polishing method of the metal film, the surface of the metal film is wrapped with the protective film with the insulating property, and electrochemical polishing is carried out. The electrochemical polishing is mainly used for removing sharp parts on the edge of the metal film, so that the edge of the metal film is smooth, soft tissue cracking is avoided, the possibility of wound infection is reduced, and the healing period of a wound is shortened.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to an edge polishing method of a metal film material, a metal film material and applications. Background technique [0002] Guided Bone Regeneration (GBR) technology is based on the characteristics of fast growth and migration of epithelial cells and fibroblasts, and slow migration of osteoblasts. A barrier film made of metal or biomaterial is placed in soft tissue. For example, a biological barrier is artificially erected between the soft tissue of the gum and the bone defect. The biological barrier can preserve the osteogenic space, prevent the fast fibroblasts and epithelial cells in the soft tissue from growing into the bone defect area, create a relatively closed environment, and ensure that the slow proliferating osteoblasts are not disturbed during the osteogenesis process. And there is sufficient time to occupy the osteogenic space and finally achieve complete bone repair...
