Abstract
The invention provides stainless steel washed white solution, which uses water as solvent, every one liter of the solution comprises 4-10 percent of nitric acid, 10-40g phosphoric acid, 2.5g boric acid, 5-30g acetic acid, 10-30g ammonium sulfate, 10-30g trisodium phosphate and 15-35g ammonium bifluoride. The method of using the stainless steel washed white solution to do the washed white process of the surface of stainless steel has the technological processes of pretreatment, degreasing, pickling, washing white, washing and baking, wherein after the stainless steel which is needed to be washed white is pretreated, degreased and pickled, the stainless steel which is pickled is put into the stainless steel washed white solution for 10-35 minutes in 55-85 DEG C, at last through washing and baking, the surface of the stainless steel is formed with an uniform silvery film layer which has a sand surface effect.
Description
[technical field]
Relevant a kind of whitening solution of the present invention and whitening technique thereof are meant a kind of stainless steel whitening solution and whitening technique thereof especially.
[background technology]
Stainless steel is because its good corrosion resistance, more and more be subjected to the attention of all trades and professions, every field at industrial sector is used more and more widely, as everyone knows, some product that the client needs must be made with stainless steel, but, the client do not have metalluster because of requiring it again, will carry out whitening technique to stainless material in this case, present whitening technique contains the nitric acid (about 40-60%) of high density more, the danger coefficient height, environmental hazard is also bigger, and it whitens effect and mostly is canescence.
In view of this, reality is necessary to develop a kind of stainless steel whitening solution and whitening technique thereof, utilizes this solution and whitens treatment process, not only can reach to whiten effect preferably, and not contain high density nitric acid, and danger coefficient is little, and is little to the harm of environment.
[summary of the invention]
Therefore, the object of the present invention is to provide a kind of stainless steel whitening solution and whitening technique thereof, utilize this solution and whiten treatment process, can form a uniform silvery white rete and have sand face effect at stainless steel surface, do not contain high density nitric acid in this solution in addition, danger coefficient is little, and is little to environmental hazard.
A kind of stainless steel whitening solution provided by the invention is a solvent with water, contains in its every liter this solution:
Nitric acid 4%-10%;
Phosphatase 11 0-40g;
Boric acid 2-5g;
Acetate 5-30g;
Ammonium sulfate 10-30g;
Tertiary sodium phosphate 10-30g;
Ammonium bifluoride 15-35g.
The present invention also provides a kind of method of utilizing described stainless steel whitening solution to carry out the stainless steel surface whitening technique, and its technical process is: pre-treatment → degreasing → pickling → whiten → wash → toast; After wherein the stainless steel that need are whitened carries out pre-treatment, degreasing, pickling earlier, be 55-85 ℃ in temperature and will put into above-mentioned stainless steel whitening solution 10-35 minute down, after washing, toast and get final product through the stainless steel after the pickling.
Compared to prior art, utilize stainless steel whitening solution of the present invention and whiten treatment process, can form a uniform silvery white rete and have sand face effect at stainless steel surface, do not contain high density nitric acid in this solution in addition, danger coefficient is little, and is little to environmental hazard.
For purpose of the present invention, structural attitude and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 utilizes stainless steel whitening solution of the present invention stainless steel surface to be whitened the process flow sheet of processing.
[embodiment]
Stainless steel whitening solution provided by the present invention is a solvent with water, contains in its every liter this solution:
Nitric acid 4%-10%;
Phosphatase 11 0-40g;
Boric acid 2-5g;
Acetate 5-30g;
Ammonium sulfate 10-30g;
Tertiary sodium phosphate 10-30g;
Ammonium bifluoride 15-35g.
See also Fig. 1, it is to utilize stainless steel whitening solution of the present invention stainless steel surface to be whitened the process flow sheet of processing.
As schematically shown in Figure 1, this technical process is:
Pre-treatment mainly is impurity and a dirt of removing stainless steel surface;
Degreasing will be put into the solution 5 minutes that contains sodium hydroxide 5g/L, Sodium dodecylbenzene sulfonate 3g/L through pretreated stainless steel down 40 ℃ of temperature;
Pickling will be put into the solution 3 minutes that contains 5% sulfuric acid, Tai-Ace S 150 10g/L through the stainless steel of degreasing down 50 ℃ of temperature;
Whiten, be 55-85 ℃ in temperature and will put into above-mentioned stainless steel whitening solution 10-35 minute through the stainless steel after the pickling down;
Washing in order to wash away after whitening operation, remains in the soup of stainless steel surface;
Baking in order to carrying out drying through the stainless steel after the washing, is removed remained on surface moisture content.
Compared to prior art, utilize stainless steel whitening solution of the present invention and whiten treatment process, can form a uniform silvery white rete and have sand face effect at stainless steel surface, do not contain high density nitric acid in this solution in addition, danger coefficient is little, and is little to environmental hazard.
