Description
Technical field
The present invention relates to stainless steel surface processing technology fields, more particularly to the polishing fluid of stainless steel 8K mirror surface.
Background technique
Mirror face stainless steel is widely applied in the fields such as building decoration, superior automobile, household electrical appliances, and 8K mirror face stainless steel is fine grinding
Mirror effect.The polishing method of stainless steel is mainly by three kinds of mechanical polishing, chemical polishing, electrobrightening methods at present.Machinery is thrown
Light refers to the injustice of the high-speed rotating polishing wheel elimination workpiece surface for being stained with sand paper or abrasive pastes, to obtain glossy surface
Machining process.Chemical polishing refer to stainless steel products in the solution of definite composition, surface microscopic convex portion it is molten
The solution rate that speed is greater than surface microscopic depressed section is solved, and makes its bright and clean smooth process.Electrobrightening refers to stainless steel
Product is hung on anode, is placed in certain polishing solution and is carried out, and microscopic protrusions part and burr first dissolve, to make surface light
It is clean smooth.
It mechanically polishes and requires the operation skill of operator very high, the noise pollution generated in process and dust dirt
Dye is very big, seriously affects to the health of operator；The polishing fluid of chemical polishing routine can generate corrosive gas
Or toxic gas such as HCl, NOx, HF etc., pollute environment, and endanger the health of operator；Electrobrightening is difficult to reach
To the requirement of the surface quality of 8K mirror surface.
Summary of the invention
Technical problem to be solved by the invention is to provide one kind will not generate the stainless steel 8K mirror surface of corrosive gas
Polishing fluid.
The technical solution used in the present invention is:
A kind of polishing fluid of stainless steel 8K mirror surface, the polishing fluid contain following components: the boric acid of 1.5-3.5 mol/L,
The sulfuric acid of 1.2-2.8 mol/L, the glycerine of 1.5-2.5 mol/L, 0.4-2 mol/L nitrate.
In some preferred embodiments, the boric acid containing 1.8-2.5 mol/L, 1.2-1.6 in the polishing fluid
The sulfuric acid of mol/L, the glycerine of 1.5-1.8 mol/L, 1.4-1.6 mol/L nitrate.
In some preferred embodiments, also containing the mannitol of 0.2-0.4mol/L in the polishing fluid.
In some preferred embodiments, also containing the acetic acid of 1.5-3.5mol/L in the polishing fluid.
In some preferred embodiments, also containing the citric acid of 1.5-2mol/L in the polishing fluid.
In some preferred embodiments, the nitrate is sodium nitrate or potassium nitrate.
In some preferred embodiments, the brightener in the polishing fluid also containing 0.1-0.5 mol/L.
In some preferred embodiments, the corrosion inhibiter in the polishing fluid also containing 0.1-0.5 mol/L.
The beneficial effects of the present invention are:
The present invention provides a kind of polishing fluids of stainless steel 8K mirror surface to throw containing boric acid, sulfuric acid, glycerine and nitrate
The strong acid of corrosive gas or toxic gas can be generated without containing hydrochloric acid, nitric acid, hydrofluoric acid etc. in light liquid, and has selected sulphur
Acid so polishing fluid of the present invention will not generate corrosive gas or toxic gas in use, but is used only
A kind of this strong acid of sulfuric acid is unable to satisfy the surface quality requirements of mirror surface, throwing of the present invention not using other strong acid such as phosphoric acid
It is also added into boric acid in light liquid, though boric acid is weak acid, boric acid can be coordinated with glycerine, promote the ionization of boric acid flat
Weighing apparatus is positive mobile, enhances the acidity of boric acid, sulfuric acid is in conjunction with the boric acid of acidity enhancing so that polishing fluid meet demand；Nitrate energy
It is enough that thin oxidation film is formed in metal surface, metal and corrosive medium are kept apart；Using polishing fluid of the present invention to not
Rust steel part directly carries out chemical polishing, enables to stainless steel products to reach the surface requirements of 8K mirror surface, can also first use
A preliminary polishing is done in mechanical polishing, is then carried out chemical polishing using polishing fluid of the present invention again, can also be made stainless steel
Product reaches the surface requirements of 8K mirror surface.
