Description
Technical field
The invention belongs to metal working technical area, and in particular to a kind of stainless steel water tank antimicrobial coating.
Background technology
Stainless steel water tank is the water tank product of new generation after Glass fabre reinforced plastic water tank, its product is using SUS304 stainless steel plates essence
Work molding forms, handsome in appearance, economical and practical, main body is prolonged not bad.Stainless steel water tank has beautiful outline form compared with other water tanks
Sight, light-weight, intensity is high, corrosion-resistant, high temperature resistant, water cleaning, antiseepage, antidetonation, never raw moss, water quality non-secondary pollution,
It is easy for installation, without maintenance, many advantages, such as easy to clean.
Present stainless steel water tank is typically all to be used for containing domestic water, these water must assure that and not be contaminated, therefore
The requirement of higher is proposed to the antibiotic property of stainless steel water tank, if stainless steel is directly simply processed as water tank to use, and
Cannot continue carry out antibacterial, the water in water tank may be caused to be contaminated, if therefore the application be intended to research improve stainless steel water
The antibiotic property of case.
The content of the invention
The invention is intended to provide a kind of stainless steel water tank antimicrobial coating, which is coated on to the interior table of stainless steel water tank
Face, improves the antibiotic property of water tank.
The present invention provides a kind of stainless steel water tank antimicrobial coating, the antimicrobial coating include sequentially connected zinc layers,
Layers of copper and composite bed, the component and mass ratio that the composite bed includes are：Boron fibre 10%, nickel oxide 20%, silica
30% and silver oxide 40%, the thickness of the zinc layers is 5~7 μm, and the thickness of the layers of copper is 4~7 μm, the thickness of the composite bed
Spend for 5~9 μm.
The working principle and beneficial effect of the present invention：
Traditional stainless steel water tank, since its inner surface does not apply any antimicrobial coating, easy Adherent bacteria, it is long this with
Past, bacterium can pollute the water in water tank, endanger people's health.And in the antimicrobial coating of the application, including it is sequentially connected
Zinc layers, layers of copper and composite bed, in use, zinc layers to be fitted in the inner surface of stainless steel water tank, the boron fibre that contains in composite bed,
Nickel oxide, silica and silver oxide have good antibacterial action, can kill most bacterium.And layers of copper and zinc layers below
It can play the role of protecting composite bed, and there is certain antibacterial effect.
In conclusion being coated on stainless steel water tank inner surface using the antimicrobial coating of the application, good resist can be played
Bacterium effect, allows people to eat stainless steel water tank more safety and trust.
Further, the thickness of the zinc layers is 6 μm.
Further, the thickness of the layers of copper is 5 μm.
Further, the thickness of the composite bed is 7 μm.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of stainless steel water tank antimicrobial coating of the present invention.
Embodiment
Below by the further details of explanation of embodiment：
Reference numeral in Figure of description includes：Stainless steel water tank 1, zinc layers 2, layers of copper 3, composite bed 4.
As shown in Figure 1, the present invention provides a kind of stainless steel water tank antimicrobial coating, antimicrobial coating includes sequentially connected
Zinc layers 2, layers of copper 3 and composite bed 4, the component and mass ratio that composite bed 4 includes are：Boron fibre 10%, nickel oxide 20%, oxidation
Silicon 30% and silver oxide 40%, the thickness of zinc layers 2 are 5~7 μm, and the thickness of layers of copper 3 is 4~7 μm, the thickness of composite bed 4 for 5~
9μm.When in use, zinc layers 2 are fitted in the inner surface of stainless steel water tank 1, you can play the effect of antibacterial.
Preferably scheme is：The thickness of zinc layers is 6 μm, and the thickness of layers of copper is 5 μm, and the thickness of composite bed is 7 μm.
Anti-microbial property test：
With reference to GB15979-2002《Disposable Sanitary Accessory sanitary standard》And Ministry of Health of the People's Republic of China《Disappear
Malicious technical specification》, anti-microbial property inspection, shadow of the research modified technique to stainless steel anti-microbial property are carried out using agar plate method
Ring.Required articles for use have：HNP-1 types horizontal manifold superclean bench, electro-heating standing-temperature cultivator, High pressure steam sterilizer and platinum connect
Kind silk etc..Concrete operation step is as follows：
Sample is cleaned with the absorbent cotton containing 75% ethanol, degreasing, and the autoclaving 30min at 121 DEG C.
Strain after inoculated and cultured is spare into the bacterium solution that concentration is 10~10cfu/ml with sterile AATCC broth dilutions.
0.1ml bacterium solutions are uniformly dropped in through autoclaved specimen surface respectively with pipette.
There are the antibacterial sample of bacterium solution and control sample to be put into the culture of 35 ± 1 DEG C of temperature, humidity more than 90% surface drop
24h Bacteria Cultures are done in case.
Viable count is measured with agar method (35 ± 1 DEG C of temperature, humidity more than 90%, time 24h).
Each strain and sample are repeated 3 times, and are averaged.Anti-microbial property is evaluated with sterilization rate, sterilization rate following formula
Calculate：
Sterilizing rate (%)=(control stainless steel aerobic plate count-anti-bacteria stainless steel aerobic plate count)/control stainless steel aerobic plate count *
100%.
In above-mentioned formula, control sample viable count refers to that compareing stainless steel curved beam carries out the viable count after bacterium culture test,
And anti-viable count refers to that anti-bacteria stainless steel sample carries out the viable count after bacterium culture test.Experimental result is shown in Table 1.
Table 1
Table 1 is the anti-microbial property of part anti-bacteria stainless steel.From table from the point of view of result, the austenite stainless before silver ion infiltration
Steel curved beam does not have any antibacterial effect；Sample after silver ion infiltration has difference to Escherichia coli and staphylococcus aureus
The antibacterial effect of degree.All infiltration samples all show Escherichia coli good antibacterial effect, sterilization rate 99% with
On；To the antibacterial effect of staphylococcus aureus be not as notable as Escherichia coli, but there is a degree of antibacterial effect.With silver
The increase of ion concentration, the antibacterial effect of sample is in obvious ascendant trend.
