1. It can completely remove the carbonate, silicate, phosphate and rust which are heated by the boiler; it also has a good dissolution effect on the sulfate scale.
2, the descaling temperature is low, the descaling temperature is controlled at 55 ° C -65 ° C;
3, the descaling corrosion rate is low, lower than (national standard) <6g/m2/h;
4, the descaling speed is fast, according to the scale thickness of 8-20 hours can complete the descaling.
Scope of application
This product is used in various pressure steam boilers, hot water boilers, locomotive boilers, flashers, smelting furnaces, electric heating steam generators, coolers, evaporators, water heating jackets and line system cleaning.
Materialization situation
Appearance light yellow liquid Water solubility: easy to dissolve Density: 20 ° C 1.05-1.08 / ml
Flammability: non-combustible ph value <1.5
Instructions
Cool the boiler to normal temperature and drain the boiler water.
Connect each drain to the dosing slag.
The cleaning agent is diluted with 1:2-3 water in the dosing solution. Use the circulating pump to drive into the highest liquid level of the boiler.
The boiler was ignited and heated to a temperature of 60 ° C.
Each sewage valve is opened separately to cycle the various pipelines.
After cleaning for a period of time according to the thickness, the pH value (acid value) of the cleaning solution is measured. When the acid value remains unchanged for half an hour before and after the acid value, a certain amount of cleaning agent is added, and the pH value is measured again and the pH value is unchanged after half an hour. Indicates that cleaning has ended.
The neutralizing agent KJR-110 neutralizes the boiler cleaning agent with a pH of 7-8 hours for external discharge. Manually clean the boiler residue, rinse the boiler to pre-film the boiler, and then enter the normal use or add protective agent to shut down the furnace.
