A method for production of dishware using plasma hybrid deposition system

Abstract

The invention relates to a method for production of dishware using a plasma hybrid deposition system. The present invention relates to dishware having an antibacterial function in the dishware which many people use to prevent the dishware from being corroded due to food, and also having a function of resisting wear to use the dishware for a prolonged time when the dishware is washed. Also, the present invention relates to the dishware which enables a user to safely take food as various bacterium are not reproduced in the dishware due to a coated functional thin film when the functional thin film having the antibacterial force on the various bacterium doing harm to the human body is coated. The present invention also relates to a manufacturing method for dishware. The dishware is prevented from being corroded due to various acid materials existing in the food; and moreover, the thin film having a composite function of preventing the dishware from being worn out by a fiber scouring pad used for washing is deposited.

Description

technical field [0001] The present invention relates to a tableware, and more particularly to a tableware and a method for manufacturing the same by imparting an antibacterial function to the tableware so as to prevent corrosion due to food, and imparting abrasion resistance to the surface of the tableware so that it can be washed even if it is frequently washed It can also be used for a long time. Background technique [0002] The most widely used tableware in the past was brass (copper-tin alloy) utensils. This kind of brass utensils is heavy and polluting substances are quickly formed on its surface during continuous use, so it needs to be washed frequently by grinding. In modern times, most of them are replaced by glass or stainless steel utensils. However, it is well known that brass (copper-tin alloy) utensils are made of antibacterial materials like silver spoons and chopsticks, but recently they are sold at very high prices due to the characteristics of the manufact...

AI Technical Summary

Problems solved by technology

This kind of brass utensils has the problem of being heavy and polluting substances are quickly formed on its surface during continuous use, so it needs to be washed frequently by grinding. In modern times, most of them are replaced by glass or stainless steel utensils

However, it is well known that brass (copper-tin alloy) utensils are made of antibacterial materials like silver spoons and chopsticks, but recently they are sold at very high prices due to the characteristics of the manufacturing process, so although there are The advantages described, but not widely used in daily life

[0003] In general, sputtering and arc ion plating are mainly used as manufacturing methods for imparting functionality to tableware. Homogenization treatment, acid, alkali or salt will cause corrosion, and a pinhole-shaped corrosion pattern will appear on the surface. As time goes by, the pinhole (Pin-hole) will gradually widen and wear on the surface of the vessel

[0004] In addition, there are utensils coated with silver nanoparticles in the tableware produced by adopting the prior art, but there is a problem that its corrosion resistance and wear resistance will be significantly reduced and cannot be used for a long time. Due to such problems, this This kind of tableware will not circulate in the market, this is the truth

In addition, products coated with brass (copper-tin alloy) on stainless steel are also marketed, and the antibacterial ability of this product has also been proven, but this product is as susceptible to acid and alkali contained in food as silver nano-plating. and salt corrosion, the wear resistance is significantly reduced, and there is a shortcoming that it cannot be used for a long time, so it has not been applied by the vessel manufacturing process.
