SpecialProperty

High Temperature Sealing AgentPHS-5000is a nickel-containing, light green powder that has better sealing effects compared to nickel acetate-based sealing agents, and due to its special composition, it has fewer undesirable phenomena such as sealing flow color and gray mist.

Box, stored in a cool and dry warehouse, direct sunlight is strictly prohibited.High temperature and heat, must be sealed properly after use.

10Precautions/With the use of sealing liquid and the introduction of water and acid-base, it will change. Use dilute acetic acid to reduceH,and use dilute sodium hydroxide solution to increase.The sealing temperature is best above

If the sealing time is too long, a powdery substance will form on the workpiece.

If the value exceeds the usage range, the sealing ability will decrease and powdery substances will also form.pHIt is recommended to use acid-resistant high-temperature filters for filtration.pManagement MethodAccurately measurepHmilliliters of solution into a conical flask.
Add about90Minutesdeionized water to the conical flask,pH10mL 25%-28% ammonia solution, and a small amount of purple carbamide indicator.milliliters of solution into a conical flask.
After shaking, usemilliliters of solution into a conical flask.

0.0100mol/L EDTA-2Na

for titration, when the solution changes from light yellow to light purple, it indicates that the endpoint has been reached.10Calculation:
(150mLPMS 168)=c*V*38.28
where c is the concentration of the sealing agent solution,and V is the volume consumed.滴定，当溶液由浅黄色变为浅紫色即为达到终点。
