Industrial Blacking Agent For Stainless Steel From Mic-ecology

Iron Blacking Agent  

Product introduction:

Steel products by blackening with decorative and antirust effect.

At present, domestic room temperature blackening products in use widespread instability of the solution, by using which produce turbid, blackening film is thin, poor adhesion, antirust performance and low, storage process easy decolour, blackening solution easy spontaneous decomposition failure etc. ills.
Blackening agent at room temperature, it is current being vigorously promote energy-saving, efficient and advanced manufacturing technology; applicable to iron and steel processing machinery parts, casting, forging the oxidative blackening (blue) and its characteristics is can effectively overcome the traditional black (blue) three major problems existing in the process of high energy consumption, low efficiency and environmental pollution to reduce energy consumption, increase benefit. Advantages compared with similar products, use the product processing of black pieces, with dense film, and basic structure of a solid, good appearance, and supporting the advanced technology, after treated by passivation process, the normal temperature dehydrating antirust oil, so that black piece corrosion capability significantly enhanced.

Scope of application:

Widely used in standard parts, auto parts, diesel engines, ships, electronics, instrumentation, aerospace, machinery manufacturing and parts, weapons,  a chain, a spring, a glib pumps, hardware tools, pumps and valves and does not allow the plating or paint processing of precision mechanical protection and decoration. Can handle various types of steel and silicon steel, cast iron and low carbon steel.  

 Product features:

Completely solve the low carbon steel, casting and forging blackening problem.        

Do not change the size of the processed workpiece accuracy.
Solution with good performance, less precipitation, long-term storage without failure, blackening film uniform, deepest blackness, decolorization, corrosion resistance.
Backening time short (5-10 minutes), easy to use, no pollution to the environment, improve working conditions, impore work efficiency, in use process does not need heating, does not consume energy.
More than 90% high temperature alkaline blackening process than the traditional energy-saving, 20-40% lower than the comprehensive cost of using domestic products.
Novel and unique formula, blackening process is simple, stable, just will send black liquor and water according to a certain mixing ratio can be put into use.

Test condition:
Outside view: uniform film, black, no rust, no hanging ash.
Corrosion resistance: sodium chloride immersion method: 30g/L sodium chloride solution, 20 degrees Celsius, soak for  3 hours.
Copper sulfate solution: 30g/L copper sulfate solution, 20 degrees C, 32 seconds.

Using method:

Degreasing-- water washing--acid washing (activation)--water washing--water washing-- blackening--passivation-- dehydration antirust oil.
In addition to oil: the use of temperature or medium temperature type of oil removal agent.
Hydrochloric acid cleaning activation: obtained in 31% of industrial hydrochloric acid 700kg and 250kg water derusting 50kg additives mixed dilution is 1000kg of hydrochloric acid solution, blackening of the workpiece is dipped in the solution for 15-30 minutes of activation.
Blackening at room temperature: use FH-RH blackening at room temperature agent a and 3-4 copies of water dilution, blackening time 5-10 minutes, pH value is maintained between 2-3, the specific operation as black blackness and, when pH > 3.0, according to 30% of the amount of tank with added.
The use of black passivation passivation: FH-DH.
Oil seal: the use of FH-fx8 dehydration rust oil.

Attention:

1, before the black except the oil and rust removal process is the key process of room temperature blackening, the processing level of quality will directly affect the adhesion and appearance of blackening film. If the hydrochloric acid pickling is not thorough, then the black film is not even or the binding force is not good, easy to fall off, please extend the pickling time.
2, blackening time length depending on the workpiece material is slightly different, after blackening of the workpiece, in  the air to stay 1.5-2 minutes, and then rinse with water for 1-2 minutes, be sure to rush as the workpiece surf a attachment and residual liquid.
3, the workpiece immersion dehydration antirust oil for 3-5 minutes, pay attention to the workpiece upside down severa  times, so that the blind hole fully processed.
4, components installed basket processing to avoid overlap in the overlap of the available gauze separated, for demanding parts, especially military components to design special racks.
5, blackening the workpiece after the completion of the operation process, surface chemical reaction has not been finally  completed, in the air under the action of oxygen will slow, the transformation process can improve the strength and adhesion of the film, blackness, uniform has also improved. Make full use of the "residual" effect, can reduce the blackening time, reduce processing costs.
