Problems solved by technology
Due to the irregular shape and certain thickness of the shell of ordinary sanitary ware, it is placed in the electric field between parallel plate electrodes or between similar special-shaped electrodes where the vacuum plasma vapor phase chemical deposition reaction occurs, resulting in an excessively large distance between the electrodes, which is difficult to Plasma is formed, so it is difficult to solve the problem of depositing diamond-like carbon films on the surface of sanitary ware using existing technologies

Embodiment Construction
[0009] The optimal solution is to use magnetron sputtering technology to coat a metal aluminum film (3) with a thickness of about 0.5 microns on the surface of the sanitary ware (4), and then put the sanitary ware (4) into the vacuum plasma vapor phase chemical deposition diamond-like film ( 2) Just below the special-shaped electrode (5) in the vacuum chamber (6) of the equipment, connect the negative pole of the high-frequency bias power supply to the metal aluminum film (3) on the surface of the sanitary ware (4), and the special-shaped electrode (5) is connected to the sanitary ware (4) The conductive film (3) on the surface of the sanitary ware (4) together constitutes a plasma electric field. The vacuum plasma vapor phase chemical deposition diamond-like film (2) device is started, and the diamond-like film (2) is deposited on the surface of the conductive film (3) on the surface of the sanitary ware (4). You can get the DLC self-cleaning sanitary ware.

The invention discloses a self-cleaning sanitary tool for DLC and belongs to the technical field of new material application. The self-cleaning sanitary tool for the DLC is composed of a sanitary tool body made of ceramic, glass, metal and plastic, a conducting film sputtered on the surface of the sanitary tool body, and diamond like carbon deposited on the surface of the conducting film, and a vacuum plasma chemistry deposit diamond like carbon (DLC for short) technology and a magnetron sputtering technology are used for producing the sanitary tool with the self-cleaning function. The diamond like carbon has the characteristics of being high in strength, resistant to abrasion, corrosion and mould, hydrophobic and oleophobic, and a firm protection film layer can be deposited and formed on the surface of the ceramic, the glass, the metal and the plastic. Inorganic dirt or organic dirt can be hardly attached to the surface of the diamond like carbon, and organic substances can be decomposed when ultraviolet rays irradiate the diamond like carbon. Thus, the self-cleaning sanitary tool for the DLC has the self-cleaning function and can also be resistant to abrasion and mould and suitable for various kitchens and toilets.
Description
1. Technical field [0001] DLC self-cleaning sanitary ware is a sanitary ware with self-cleaning function produced by vacuum plasma chemical deposition diamond-like carbon film (abbreviated as DLC) technology and magnetron sputtering technology. Its technical field is the application of new materials. 2. Background technology [0002] Diamond-like carbon films are functional materials with diamond properties. The diamond-like film produced by vacuum plasma vapor phase chemical deposition has the characteristics of high hardness, wear resistance, corrosion resistance, mold resistance, hydrophobicity and oil repellency, and can be deposited on the surface of ceramics, glass, metal and plastic to form a firm protective film layer . Both inorganic and organic dirt are difficult to adhere to the surface of the diamond-like carbon film, and the diamond-like carbon film can also decompose organic matter when irradiated by ultraviolet light. Therefore, the diamond-like carbon film ...
