A special device for providing water vapor for a vacuum coating machine and its use method

Abstract

A device special for providing water vapor for a vacuum coating machine comprises a metal tank, a sealing ring, a tank cover, a first vacuum valve, a second vacuum valve, a water inlet hose and a metal air exhausting pipe and is characterized in that the upper portion of the metal tank is provided with a cornice, the cornice is provided with bolt holes and is internally provided with an inner cavity, a first metal pipe and a second metal pipe are arranged on the side face of the metal tank, the sealing ring is placed between the tank cover and the cornice, through holes are formed in the edge of the tank cover, bolts penetrates through the bolt holes, round holes and the through holes to string the metal tank cover, the sealing ring and the tank cover together, bolt sleeves are screwed on the bolts, and the metal tank cover, the sealing ring and the tank cover can be fixed to form a whole. One end of the first vacuum valve is connected with one end of the water inlet hose, the other end of the first vacuum valve is connected with one end of the first metal pipe, and the other end of the first metal pipe is welded on the side face of the metal tank. One end of the second vacuum valve is connected with one end of the metal air exhausting pipe, the other end of the second vacuum valve is connected with one end of the second metal pipe, and the other end of the second metal pipe is welded on the metal tank. The device provides water vapor for a vacuum chamber, is simple in operation, safe and controllable, saves energy and is environmentally friendly.

Description

technical field [0001] The invention belongs to the technical field of water vapor generation, and in particular relates to a special device for providing water vapor for a vacuum coating machine. Background technique [0002] Coagulation is a major problem on the surfaces of biological devices and artificial organs that come into contact with blood, and improving anticoagulant properties is crucial for the development and application of such biomaterials. The blood compatibility of the surface of inorganic thin film materials is closely related to the structural properties of the material, especially the surface properties. Therefore, the relationship between the structural properties of the material surface and the anticoagulant property is investigated to understand the interface behavior between the material surface and blood , to reveal the anticoagulant surface modification mechanism, and to explore material processing techniques and methods, which have important theor...
