preparation example Construction

[0031] The preparation method of the vacuum-coated pill carrier of the present invention mainly includes the preparation of stainless steel microfilament felt and punching the inner core.

[0032] Stainless steel microfilament mat preparation. First select stainless steel microwires with a diameter of 20-40 microns, and use a fiber stretcher to cut the stainless steel microwires to a suitable length as the substrate. As an embodiment of the present invention, it can be cut to 50cm or other sizes to adapt to the desired Factors such as the size of the pressing die and the sintering furnace are determined. Then, the stainless steel microwires are uniformly and non-woven paved on the forming net, and 8-10 layers are paved to obtain the superimposed layer of the stainless steel microwires. A high-temperature-resistant isolation layer is placed on the superimposed layer, and 8-10 layers of microfilament superimposed layers are continued to be non-woven on the isolated layer. Accor...

Abstract

The invention relates to a preparation method of a vacuum coating pill carrier, which comprises the following steps: laying a plurality of layers of stainless steel microfilaments in a vacuum furnace in a non-woven manner, and sintering for 30-60 minutes under 10 <-2 >-10 <-3 > Pa and 800-1000 DEG C to obtain a uniform stainless steel microfilament felt; the stainless steel microfilament felt is pre-punched into a cake-shaped initial inner core under the action of pressure; and stamping the cake-shaped initial inner core into the metal crucible to obtain a carrier finished product of which the inner core is tightly arranged in the metal crucible. Inner core punching is completed through a special punching device (100) which comprises a punching rod assembly (40), a punching platform (30), a pre-pressing die (10) and a metal crucible positioning die (20), round-cake-shaped inner cores consistent in size, thickness and weight can be obtained, the surface cleanliness completely meets the requirement, corrosion resistance is achieved, oxidation and rusting are not likely to happen, it is guaranteed that the performance of pills is stable, and the service life of the pills is prolonged. The adsorption of the liquid medicine and the volatilization rate of the liquid medicine in the thermal evaporation process are consistent, and the uniformity of the finally formed film layer is better. The process is simple and efficient, and labor is greatly saved.

Description

technical field [0001] The invention relates to the technical field of vacuum coating, in particular to a method for preparing a vacuum coating pill carrier and a specific device. Background technique [0002] In the prior art, in a vacuum environment, the medicine adsorbed in the carrier is vaporized by means of resistance or electron gun heating, and the active ingredients of the medicine are deposited on the surface of the substrate, and chemically react with the surface of the substrate to form specific properties. film layer, such as a relatively dense, low surface energy anti-fingerprint layer. Compared with the liquid state of traditional potions, some potions in the prior art exist in the form of solid pills—such as anti-fingerprint pills—which effectively reduce the risk of transportation and use, which is more and more coating manufacturers now prefer A product of choice. [0003] Vacuum coating pills are composed of two main parts: anti-fingerprint potion and ca...
