Abstract
The invention relates to a rust prevention method for a stainless steel product. The rust prevention method is characterized by comprising the following steps of: (1) soaking the stainless steel product in citric acid solution with mass percentage concentration of 4% to 6%, and boiling for 5 to 8 minutes; (2) taking out and drying; and (3) soaking the dried stainless steel product into a rust preventive for 2 to 4 minutes, wherein the rust preventing oil comprises the following components by mass percent: 5 to 15% of citric acid, 1 to 5% of ammonium nitrate, 5 to 15% of dirt dispersion agent, 1 to 5% of penetrant, and the balance of water. The rust prevention method is simple in process and shows good corrosion and rust prevention effects.
Description
Technical field
The present invention relates to a kind of rust-proofing method, especially a kind of rust-proofing method of stainless steel product.
Background technology
, although be known as stainless steel, also often there is oxidizing reaction in a lot of stainless steel products, causes variously due to use or maintain improperly in use, or the residing environment of stainless steel is too severe, the phenomenon of getting rusty.Especially in the junction of stainless steel product or without the surface of handling well completely, usually having rusty stain affects product and uses and shorten product life.The derusting method of at present conventional stainless steel product is generally: (1) is totally clean by the face of weld of ferritic stainless steel weldment, and then evenly stamps one deck silica gel from solder joint; (2) ferritic stainless steel weldment is docked with another ferritic stainless steel weldment, install and lock, start spot welding, point welds the required casing of rear formation; (3) cleaning work that will overflow immediately to casing silica gel after welding.This technique need to be stamped one deck silica gel at the solder joint place of stainless steel weldment, thereby realizes antiseptic and rustproof effect, and it is consuming time that such method is processed consumption power, and silica-gel coating is easily in use loss also.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of rust-proofing method of stainless steel product is provided, technique is simple, antiseptic and rustproof effective.
According to technical scheme provided by the invention, the rust-proofing method of described stainless steel product, is characterized in that, comprises following processing step:
(1) stainless steel product being immersed to mass percentage concentration is to boil 5 ~ 8 minutes in 4 ~ 6% citric acid solution;
(2) take out and be dried;
(3) dried stainless steel product is immersed in rust-preventive agent and soaked 2 ~ 4 minutes, the component of described slushing oil is: 5 ~ 15% citric acids, 1 ~ 5% ammonium nitrate, 5 ~ 15% dirt dispersion agents, 1 ~ 5% permeate agent, and surplus is water, unit is mass percent.
The present invention has the following advantages: the processing that (1) the present invention first adopts citric acid to boil before stainless steel product dipping rust-preventive agent is processed, this technique is equivalent to pickling, make stainless steel surface generation passivation reaction, remove irony and other ironys of getting rusty of stainless steel surface, thereby stainless steel vessel can not be got rusty; (2) after citric acid boils processing, again stainless steel product is soaked in rust-preventive agent, can obviously improve the antiseptic and rustproof effect of product.
Embodiment
Below in conjunction with specific embodiment, the invention will be further described.
Embodiment mono-: a kind of rust-proofing method of stainless steel product, comprises following processing step:
(1) stainless steel product being immersed to mass percentage concentration is to boil 8 minutes in 4% citric acid solution;
(2) take out and be dried;
(3) dried stainless steel product is immersed in rust-preventive agent and soaked 2 minutes, the component of described slushing oil is: 5% citric acid, 1% ammonium nitrate, 5% dirt dispersion agent, 1% permeate agent, and surplus is water, unit is mass percent.
Embodiment bis-: a kind of rust-proofing method of stainless steel product, comprises following processing step:
(1) stainless steel product being immersed to mass percentage concentration is to boil 5 minutes in 6% citric acid solution;
(2) take out and be dried;
(3) dried stainless steel product is immersed in rust-preventive agent and soaked 4 minutes, the component of described slushing oil is: 15% citric acid, 5% ammonium nitrate, 15 dirt dispersion agents, 5% permeate agent, and surplus is water, unit is mass percent.
Embodiment tri-: a kind of rust-proofing method of stainless steel product, comprises following processing step:
(1) stainless steel product being immersed to mass percentage concentration is to boil 6 minutes in 5% citric acid solution;
(2) take out and be dried;
(3) dried stainless steel product is immersed in rust-preventive agent and soaked 3 minutes, the component of described slushing oil is: 10% citric acid, 2% ammonium nitrate, 10% dirt dispersion agent, 2% permeate agent, and surplus is water, unit is mass percent.
The stainless steel product surface-brightening homogeneity that the present invention obtains the smoke test of 5% concentration 98 hours, and is soaked 4 hours in salt solution, and product can not get rusty.The present invention's stainless steel product surface anticorrosion after treatment favorable rust preventing effect, the work-ing life of having improved stainless steel product.
Claims (1)
