~495 DEG C；Band-like continuous glass sheets after annealing are cut into the glass plate of specified size, and glass plate is sent at activation
It manages in pond, treatment fluid is housed in the activation process pond, the treatment fluid is the silver nitrate solution that mass fraction is 35%, activation
The bottom of pond of processing pond is equipped with supersonic generator, and the glass plate liquid to be treated submergence in activation process pond is then in 35KHz
Frequency under ultrasonic disperse 3h carry out activation process operation.Glass plate after activation process operation is admitted to oxidation processes
Chi Zhong, the hydrogen peroxide for being 5% equipped with mass fraction in the oxidation processes pond, the bottom of pond in the oxidation processes pond are equipped with ultrasound
Wave producer, by dioxygen water immersion, then ultrasonic disperse 2h is carried out the glass plate in oxidation processes pond under the frequency of 35KHz
Oxidation processes operation.Glass plate after the completion of oxidation processes operation again drying to the antibacterial float glass.
The thickness of the antibacterial float glass is 7mm, and the stripping quantity of silver ion is 156mg/ (g24Hrs).The antibacterial is floating
Method glass has apparent fungistatic effect to staphylococcus aureus, Escherichia coli, typhoid bacillus, corynebacterium diphtheriae, especially right
The fungistatic effect of corynebacterium diphtheriae is stronger.Its bactericidal effect after outdoor application 8 years of the antibacterial float glass has dropped
37.2%。
In the above-described embodiments, the stripping quantity of the silver ion is the 100mL that 10g antibacterial float glass is immersed in 25 DEG C
In distilled water, sonic oscillation measures for 24 hours under the frequency of 10 ~ 15KHz.Wherein, the thickness of the antibacterial float glass is blocked up
Then so that the stripping quantity of silver ion reduces；The thickness of the antibacterial float glass is excessively thin, makes under its bacteriostasis duration
Drop, it is therefore desirable to strictly control the thickness of the antibacterial float glass.
Quartz sand, aluminium oxide, soda ash, calcium carbonate, magnesia are the necessary raw material of float glass.The antibacterial float glass process glass
Glass contains titanium oxide, and titanium oxide can have bactericidal effect under ultraviolet irradiation, kill the bacterium of glass surface.
In modified silver nitrate, the phosphoric acid hydrogen zirconium have larger specific surface area and surface charge, have it is good from
Sub- commutativity occurs slowly to decompose at 1600 DEG C or more, and consistency declines.Therefore, environment of the silver nitrate in ultrasonic disperse
It is easily attracted to down on phosphoric acid hydrogen zirconium, methyl-silicone oil is as carrier so that silver nitrate can be combined preferably with phosphoric acid hydrogen zirconium, first
Base silicone oil easily resolves into silica, carbon dioxide and water at high temperature, and carbon dioxide and water are finally discharged from glass melts,
Silica becomes one kind of ingredient in glass；It will not carry out impurity to glass tape using methyl-silicone oil.The silver nitrate is in height
Temperature is lower to decompose, and band-like continuous glass sheets contain silver, silver oxide.Relative to the addition oxidation silver material directly into raw material, final
The control group glass arrived, the stripping quantity of silver ion are the 30 ~ 47% of antibacterial float glass of the present invention；Also, the present invention is anti-
Bacterium float glass is to 1.9 ~ 2.1 times that the fungistatic effect of corynebacterium diphtheriae is control group glass.Due to the glass plate after just annealing
If directly using, silver ion therein is not easy to dissolve out；Using silver nitrate solution and under the oscillation treatment of ultrasonic wave so that glass
Glass blanket is activated, and silver ion therein is more easy to dissolve out, and the stripping quantity of the silver ion of antibacterial float glass of the present invention can reach
To 161mg/ (g24Hrs).
The silver element on glass plate surface can be oxidized to oxygen by the hydrogen peroxide in oxidation processes pond under the environment of ultrasound
Change silver, silver oxide stable components so that the antibacterial float glass can subsequently stablize, lasting precipitation silver ion, use
Service life is permanent.It is water that silver element is oxidized to the product after silver oxide by hydrogen peroxide, this makes glass surface not consolidated again by other
Body particle exchanges, and does not influence glass surface character.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all essences in the present invention
All any modification, equivalent and improvement etc., should all be included in the protection scope of the present invention made by within refreshing and principle.
