Abstract

The glass or ceramic utensils able to automatically disinfect and supplement zinc is made up by vacuum plating Cu-Z-Ag-Ce alloy film to the surface of glass or ceramic utensils as substrate. Said alloy contains Cu (20-60 wt.%), Zn (38-79), Ag (0.5-2) and Ce2O3 (0.001-0.004). Its advantages are high disinfecting speed and efficiency, and supplementing Zn ions to user.

Description

Automatically disinfecting and zinc-supplementing glass, pottery and manufacturing process thereof
The present invention relates to automatically disinfecting and zinc-supplementing glass, pottery and manufacturing process thereof, belong to the silicate field.
Minority both domestic and external for many years area and special occasions once adopted silver, copper plasma to make disinfection of drinking water or clinical wound disinfection is handled.Both at home and abroad silver, copper were burnt inside with the form of enamel, ceramic glaze in the last few years, brought into play its germicidal action during use.The ceramic tile and the snitaryware with anti-streptococcus aureus (MRSA) effect of Japanese Dong Tao company development introduced in article " anti-bacteria ceramic " in the first phase in 1996 " external techwatch ", and it is by at ceramic tile with one deck titanium oxide is burnt on the snitaryware surface and silver ions reaches sterilization effects.The same year, the Chinese public health journal was delivered " research of photochemistry enamel sterilization effect of tableware disinfection ", and this tableware also adds certain amount of copper oxide except that burning to have at cover-coat enamel in cover-coat enamel the titanium dioxide.This kind sterilization tableware also is by titanium dioxide and the germicidal action that has cupric ion to participate in." modern science and technology collected translation " the 6th phase in 1998 disclosed the commodity technology portion of Nippon Steel Corporation that Zhang Dongfeng translates and has developed " anti-bacteria stainless steel ".This anti-bacteria stainless steel (NSSAM-1) is that copper is dissolved in the stainless steel, and the chemical ingredients of this anti-bacteria stainless steel is C, Si, Mn, Cr, Cu, N and a spot of trace element.The thing of isolating by copper reaches antimicrobial characteristic.The cupric stainless steel was 99.99% to colibacillary killing rate in 24 hours.
The purpose of this invention is to provide a kind of glass, pottery and the manufacturing process thereof that can automatic sterilization can give the human body zinc supplementation again.The vessel of being produced also have very strong automatic sterilization effect beyond the advantage that keeps original glass, pottery.Human body also can have part zinc supplementation effect when using these vessel.Said products is applicable to that very no disinfecting power or envrionment conditions do not allow the various containers of disinfectant tableware, tea set and food etc.
This automatically disinfecting and zinc-supplementing glass, pottery are included in glass commonly used, earthenware porcelain receptacle, tableware top layer plating layer of metal alloy, make its performance sterilization zinc supplementation effect.Feature of the present invention is unique glass, the proportioning of pottery overlay coating metallic element and technology of vacuum plating.Automatically disinfecting and zinc-supplementing glass of the present invention, the shared weight percent of each metallic element of pottery overlay coating are that copper 20-60%, zinc 38-79%, silver-colored 0.5-2%, cerous oxide 0.001-0.004%, surplus are unavoidable impurities.
The manufacturing process of the said automatically disinfecting and zinc-supplementing glass of the present invention, pottery, it is a technique for vacuum coating: be magnetron sputtering plating, comprise: substrate surface treatment step before (1) plating; (2) controlled sputtering source copper, zinc, silver, Ce elements alloys target fabrication and installation step; (3) take out low, high vacuum step; (4) applying argon gas carries out sputter clean, sputter coating step; (5) logical atmosphere, getting tool step; (6) inspection after construction packaging step.
Characteristics such as with various glass, potteries that can automatically disinfecting and zinc-supplementings that the present invention makes, it be fast to have sterilization speed, and sterilizing rate height, influence factor are few.Experiment shows, automatically disinfecting and zinc-supplementing glass of the present invention, pottery are to intestinal bacteria (8099) and represent the index F of enterovirus 2(the host bacterium is E.Coli to have a liking for thalline; 285 strains) 1 hour killing rate is all greater than 99.99%; Human body also has part zinc supplementation effect when using this automatically disinfecting and zinc-supplementing glass, pottery.Through testing at 0.0015m 3The dress pure water is 1.0 liters in the volumetrical goods, and 1 hour leachable zine ion 0.11-0.15mg, this dosage can satisfy one day requirement of adult.
The present invention has also introduced this rare earth element of cerium when selecting copper, zinc, silver element for use, it can suppress the Ag ion and lose germ-resistant activity because of long wave ultraviolet in the absorption daylight is reduced into the Ag element.Because the Ce ion can absorb long wave ultraviolet in a large number, so just be suppressed with the Ag ionic reduction of Ce ion coexist, make the performance of Ag ion active, thereby copper zinc-silver ionic Cf and sterilization intensity have been improved, also increase glass, the sterilization of pottery, sterilization timeliness in addition so greatly, prolonged its action effect.
Automatically disinfecting and zinc-supplementing glass, the pottery made with the present invention have automatically disinfectant characteristics fast, thereby can save the pharmaceutical chemicals and the energy of the required usefulness of routine disinfection, and certain zinc supplementation health-care effect is arranged.
Below in conjunction with embodiments of the invention the present invention is done more detailed explanation, but the present invention is not limited to these detailed descriptions.Embodiment 1-5
