Stainless steel pickling passivation solution

Outline

The corrosion resistance of stainless steel is mainly determined by the chemical properties of the surface passivation film (component structure) and the passive film on the surface physical state. By design, optimization, to improve stainless steel surface passivation film chemical composition and surface state, the product can mate raise the degree of the stainless steel surface corrosion resistance, remove the stainless steel oxide scale, while the stainless steel surface composition of the passive film

Advantages

1, due to its stainless steel surface oxidation leather has excellent cleaning ability, you can clean the thermal processing with the stainless steel of the oxide scale.

2, this stainless steel pickling passivation solution can be acid passivation step, it simplifies the pickling process and equipment.

3, stainless steel white light and beautiful surface, and form excellent passive film, and improve the surface quality of pickling.

4, This product does not decompose, no precipitation, convenient transportation and shelf life of three years, used with the check Scope of application:

Widely used in chemical, pharmaceutical, paper, food, aerospace, nuclear industry, construction and other stainless steel equipment, pressure vessels, the surface treatment of the engineering components.

Instructions for use:

1, soaked with the acid passivation tank material must be plastic (acid and alkali material).

2, can also scrub with a brush or spray pickling method.

3, such as stainless steel surface oil can be used acetone and other solvents or stainless steel degreasing solution to remove.

4, to ensure sufficient reaction time (5-120 min), temperature (room temperature to 50 degrees) is proportional to the pickling effect (according to the oxide scale thickness). 0 ° C the following construction of an appropriate extension of time.

5 stainless steel surface with a clean water rinse loose residues can not have residual acid passivation solution. Wastewater concentrate on caustic neutralization, the pH value adjusted to neutral before discharge.

Detection means

Use common international stainless steel blue dot to detect liquid detection

Note

1, the operations must be conducted outdoors or in well-ventilated room.

2, the operator must do the protective measures strictly forbidden skin and pickling passivation solution in direct contact, such as do not need to rinse immediately with plenty of water accidentally splashed on skin or eyes.
