Description
Technical field
The present invention relates to a kind of stainless production method.
Background technology
Stainless steel products has been widely used at aspects such as food, tableware, medical apparatus and instruments at present, and this also makes rustless steel just face
Easily the microorganism such as breed bacteria, fungus and form the biomembrane of one layer of permanence, the healthy generation to people of this layer of biomembrane
Threaten greatly.So along with the raising of people's living standard, people to have safety, persistently, efficiently, the antimicrobial form of wide spectrum not
The demand of rust steel gets more and more.
Antimicrobial form rustless steel in the market mainly includes adding copper anti-bacteria stainless steel, face coat anti-bacteria stainless steel, adding
Silver anti-bacteria stainless steel etc., adds copper corrosion resistant plate Technology for Heating Processing complicated, and copper adds and too much also results in rustless steel micro-crack and increase,
In some medium the most corrosion-resistant, finally make to add copper type rustless steel high cost, it is therefore desirable to the addition of strict limit copper, this is also
Make to add copper type rustless steel antibacterial ability the strongest.Face coat type anti-bacteria stainless steel mainly has stainless steel surfaces covering one layer two
Thin film of titanium oxide, the ultra-violet absorption that the wavelength in daylight is only less than 400nm due to titanium dioxide is strong, so in illumination relatively
In the weak or use environment of unglazed photograph, this antimicrobial form rustless steel antibacterial effect is the best.So it is comprehensive from safety and antibiotic property
Consider to add silver type anti-bacteria stainless steel best, but silver-colored or silver-colored compound combined process its antibacterial effect different from rustless steel and
The difference of cost is very the biggest.
Summary of the invention
The present invention has designed and developed a kind of stainless production method.
The technical scheme that the present invention provides is:
A kind of stainless production method, including:
Step (1) first carries out alkali cleaning, chemical oxidation and pickling successively to stainless steel work-piece, obtains primary workpiece, wherein, institute
The process stating chemical oxidation is: be placed in by stainless steel work-piece in a vaporium, in vaporium be full of water vapour, chemical oxidation time
Between be 1～2h, afterwards stainless steel work-piece is taken out from vaporium, then immerses concentrated sulfuric acid solution 5min；
Silver colloid is sprayed on primary surface of the work by step (2), and spraying flow is 0.1～0.5mL/min, and spray time is

Preferably, in described stainless production method, in described step (1), after overpickling, also by stainless
Steel workpiece is placed in water 10min, further takes out afterwards, is placed at 150 DEG C drying.
Preferably, in described stainless production method, in described step (2), spraying flow is 0.1mL/min,
Spray time is 3h.
Preferably, in described stainless production method, in described step (2), it is placed at 350 DEG C sintering 35min.
Stainless production method of the present invention achieves the preparation of anti-bacteria stainless steel, the rustless steel tool prepared
Standby good antibiotic property.
Detailed description of the invention
The present invention is described in further detail below, with make those skilled in the art with reference to description word can evidence
To implement.
The present invention provides a kind of stainless production method, including:
Step (1) first carries out alkali cleaning, chemical oxidation and pickling successively to stainless steel work-piece, obtains primary workpiece, wherein, institute
The process stating chemical oxidation is: be placed in by stainless steel work-piece in a vaporium, in vaporium be full of water vapour, chemical oxidation time
Between be 1～2h, afterwards stainless steel work-piece is taken out from vaporium, then immerses concentrated sulfuric acid solution 5min；
Silver colloid is sprayed on primary surface of the work by step (2), and spraying flow is 0.1～0.5mL/min, and spray time is
2～3h, be placed at 300～350 DEG C sintering 30～35min.
The present invention, by stainless steel work-piece is carried out alkali cleaning, chemical oxidation and pickling, makes the surface of stainless steel work-piece occur
There is hole in the defect of microcosmic, the i.e. surface at stainless steel work-piece.Wherein, when stainless steel work-piece is placed in vaporium, water
The surface of stainless steel work-piece is corroded by steam, and the microcosmic position making stainless steel work-piece surface occur combines instability, afterwards
Being immersed in by stainless steel work-piece in the concentrated sulphuric acid with strong oxidizing property, above-mentioned microcosmic position is corroded by concentrated sulphuric acid further again, increases
Add the order of severity of the defect on stainless steel work-piece surface.
When silver colloid is sprayed on primary surface of the work, silver colloid is deposited in above-mentioned hole.After oversintering, elargol
Solvent composition volatilization in body is clean, and silver particles deposits and cover the surface of primary workpiece, plays antibacterial action.
The present invention can reach more than 99.4% to colibacillary antibacterial test.
Preferably, in described stainless production method, in described step (1), stainless steel work-piece is being carried out alkali
Before washing, also with the surface of grinder buffing stainless steel work-piece, the polishing time is 20min.In order to increase primary workpiece further
Roughness, increases the bond strength of silver particles and primary surface of the work, also stainless steel work-piece is carried out physics polishing.
Preferably, in described stainless production method, in described step (1), after overpickling, also by stainless
Steel workpiece is placed in water 10min, further takes out afterwards, is placed at 150 DEG C drying.On the one hand this step can wash acid solution, separately
On the one hand the region that stainless steel work-piece surface is unstable can be washed away, so that rejected region is exposed out, make silver granuel
Son can be deposited on these rejected regions.
Preferably, in described stainless production method, in described step (2), spraying flow is 0.1mL/min,
Spray time is 3h.
Preferably, in described stainless production method, in described step (2), it is placed at 350 DEG C sintering 35min.
Although embodiment of the present invention are disclosed as above, but it is not restricted in description and embodiment listed
Using, it can be applied to various applicable the field of the invention completely, for those skilled in the art, and can be easily
Realizing other amendment, therefore under the general concept limited without departing substantially from claim and equivalency range, the present invention does not limit
In specific details.
