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
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
