Abstract
The invention discloses a kind of white inorganic agent of stainless steel acid and its treatment process, contain in every 1000ml inorganic agents：Hydrogen peroxide, 150 250 ml；Citric acid, 80 120g；NaF, 40 60g；9,8 15g of surfactant LAE；Sulfuric acid, 35 60ml；Fluotitanic acid, 30 50ml.It provided by the present invention for the white inorganic agent of stainless steel acid, can be used for the surface passivating treatment of stainless steel, one layer of fine and close protective film can be formed in stainless steel surface, which has excellent corrosion resisting property, and surface brightness is high.
Description
Technical field
The present invention relates to a kind of white inorganic agents of stainless steel acid, belong to metal material surface engineering field.
Background technology
Stainless steel refers to some steel with high chemical stability in the media such as empty gas and water, brine, and excellent is anti-
Corrosive nature makes it more and more be paid attention in all trades and professions.In some occasions, need to carry out stainless steel surface blunt
Change handle, but at present existing inorganic agent deposit after treatment the antirust of protective film, anti-corrosion, wear-resisting property is insufficient, handle simultaneously
Rear surface finish it is also not ideal enough.
Invention content
The purpose of the present invention is to provide one kind for the white inorganic agent of stainless steel acid, can be used at the surface passivation of stainless steel
Reason can form one layer of fine and close protective film in stainless steel surface, which has excellent corrosion resisting property, and surface-brightening
Degree is high.
To achieve the goals above, the technical scheme is to design a kind of white inorganic agents of stainless steel acid, per 1000ml
Contain in solution：
The present invention also provides a kind for the treatment of process for above-mentioned inorganic agent：
Step 1, it would be desirable to which the stainless steel of processing is pre-processed, and is included in oil removing in industrial cleaning agent, washing three times；
Step 2, by step 1, treated that stainless steel is placed in inorganic agent impregnates 10-15min at 25-35 DEG C；
Step 3 washes the stainless steel of step 2 processing at 25-35 DEG C；
Step 4, by step 3, treated that stainless steel carries out drying and processing at 60-80 DEG C.
Compared with the prior art, the advantages of the present invention are as follows：Use the treatment agent formula treated stainless steel surface light
Brightness is high, and has higher corrosion resisting property, can be with more than the 7000h of resistance to neutral salt spray test, and the inorganic agent can return completely
It receives, safety and environmental protection.
Specific implementation mode
Present invention aims at one layer of fine and close protective film is obtained later by processing in stainless steel surface, can be used for stainless
The surface passivating treatment of steel.
【Embodiment 1】
650ml pure water will be measured first, and 80g citric acids and 40gNaF are added in water and are stirred, later by 30ml
Fluotitanic acid, which is added thereto, to be continued to stir, and is added thereto 30ml hydrogen peroxide (30wt%) after standing 1min and is continued to stir, further
The 35ml concentrated sulfuric acids (98wt%) are slowly added, 8g surfactants LAE-9 is eventually adding.
It will be placed in above-mentioned solution after impregnating 10min at 30 DEG C and taken by the stainless steel parts after oil removing and washing
Go out at 25 DEG C and carries out drying and processing after washing twice at 70 DEG C.
Corrosion resistance measurement is carried out under neutral salt spray test, the time of apparent spot occurs as testing standard using surface, when
Between it is longer, show that corrosion resistance is better.
【Case study on implementation 2】Formula is shown in Table 1, and preparation process is identical.
【Case study on implementation 3】Formula is shown in Table 1, and preparation process is identical.
Table 1
Stainless steel through being handled in the various embodiments described above can be formed on its surface one layer of fine and close protective film, the guarantor
Cuticula surface smoothness is high, and under neutral salt spray test environment product corrosion resisting property in 7000h or more.Implemented by comparing
With comparative example 1 it can be found that when not adding hydrogen peroxide, the neutral salt spray test time drastically declines example 1；Embodiment 2 and implementation
Example 3 is increased relative to 1 each component content of embodiment, while the neutral salt spray time also increases.Comparing embodiment 2 and comparative example
2 it can be found that addition fluotitanic acid can increase substantially the neutral salt spray time.
Above example is merely illustrative of the invention's technical idea, and protection scope of the present invention cannot be limited with this, every
According to technological thought proposed by the present invention, any change done on the basis of technical solution each falls within the scope of the present invention
Within.
