Black Oxide Zinc Aluminum Coating / Galvanic White Passivation Zinc Plating

 

Blackening Agent

 

JH-9201 is water based weak alkaline blackending agent, which is utilized of tempering heat provides black coating on the surface of the material. Environmental friendly, good black color effect, high gloss film

layer, excellent anti-rust function.

 

Characterstics

 

1. Adopt internal and external flim combined surface treatment,excellent anti-corrosion performance.

2. Excellent high temperature resistance and aging resistance.

3. The black film is quickly solidified,no sticky,high-gloss,and have no scraping phenomenon.

4. Environmental friendly,nontoxic and non volatility

Materials proporation method

 

Afterheat blackening agent is 100% concentrate original liquid,packed in plastic drum. Preparation blackening agent,first determine the total amount liquid,accommodated by the use of the method of concentration requirements,take about 1/10 blackening to the working tank, add water to the total amount,start the circulation pump and stirring device,make the blackening agent fully mix with water.

 

Method of application

  • Use concentration: the normal use of afterheat blackening agent concentration is 8-10% (blackening agent and water 1:9-1:14), improve the concentration can increase blackening and anti-rust effect,can adjust according to the size of workpiece and capacity,suggested max concentration no more than 15%, the min no less than 6%.
  • Recommended temperature of room temperature ~ 80 ℃, with prolonged time of use,the solution temperature due to the heat into the workpiece increases,suggest cycle cooling of blackening liquid.
  • The workpiece is heated to 220-550 ℃,then can put into blackening liquid instant black, depending on different materials the metal parts,blackening time is generally 50s ~ 2min, to ensure the cleanliness of the surface before the black, if oil or rust , you need to clean rust, in order to ensure uniform film.
  • Take the workpiece out of blackening liquid, without washing,100-120 ℃ hot air drying, oiling Packaging
  • Application range

Suitable for ML35,35,35K, 45,1018,1022,20Cr, 35CrMo, 40Cr, 42CrMo, 40CrMn, 40CrMnMo, 30CrMnSiA, 40Cr2MoV and other materials of ordinary carbon steel,alloy steel,powder metallurgy parts and other steel parts;suitable for mesh belt furnace,pit furnace,multi-purpose furnace, box-type heat treatment furnace and other equipment.

 

Maintenance method

 

1.Regularly inspect PH value of blackening agent,add new solution in time,the pH was controlled at 7.0 - 9.0.

 

2.Add blackening agent according to the production capacity,use after stirring,add a small amount each time,try to keep blackening agent system stable.

 

3.JH-9201 after long-term use,will have insoluble sediment at the bottom of the solution, it is recommended once every six months to a year to clean the tank.

 

 

4.If the blackening agent tank aging serious,there is no improvement to add JH-9201 continuously,should replace the whole tank.

 

5.When stop production for a long time, it is recommended that the open loop device on a regular basis and add microbicides to prevent corruption
