Product Name: High Temperature Sealing Agent

Model/Specification: FK004

Product Features:
High temperature sealing agent FK004 is a nickel containing, light green powder. Compared with nickel acetate based sealing agents, it has better sealing effect. Due to the effectiveness of its special components, there are fewer adverse phenomena such as sealing flow color and fog.

Conditions of Use：

Packaging and Storage:
10kg/box, stored in a cool and dry warehouse, strictly prohibited from direct sunlight, high temperature and heat. After use, it must be covered and sealed.
matters needing attention:
With the use of sealing solution and the introduction of water and acid-base, the pH will change. Reduce pH with dilute acetic acid and increase pH with dilute sodium hydroxide solution.
The best sealing temperature is above 90 ℃. If the sealing time is too long, powder will be produced on the workpiece. If the pH value exceeds the range of use and the sealing ability decreases, powdery substances will also be produced.
It is recommended to use acid resistant and high-temperature filter machines for filtration.

management:
1. Accurately measure 10 milliliters of solution and add it to a conical flask.
2. Add approximately 150mL of deionized water, 10mL of 25% -28% ammonia water, and a small amount of ammonium purple urea indicator to the conical flask.
3. Shake well and titrate with 0.0100mol/L EDTA-2Na. The endpoint is reached when the solution changes from light yellow to light purple.
Calculation: C (FK003)=c * V * 33.18
C is the concentration of the sealing agent solution - g/L, c is the mass concentration of EDTA - mol/L, and V is the volume of EDTA consumed - mL.
