Q1. What is mean of TTR & why required for powder coating process ?
Ans. 
TTR stands for Total Thickness Range and is required for powder coating process to ensure proper adhesion and durability.
• TTR is the range of thickness of the substrate and any coatings applied to it

• It is important for powder coating as it ensures proper adhesion and durability

• If the TTR is too large, the coating may not adhere properly or may crack and peel over time

• Examples of substrates with varying TTR include alumi

Q3. Which condition PH decrease in conversion coating?
Ans. 
Decrease in pH can occur due to various factors in conversion coating.
• Decrease in pH can be caused by the addition of an acid or acidic solution.

• Presence of reactive metals in the coating can lead to a decrease in pH.

• Contamination by organic materials or impurities can also lower the pH.

• Chemical reactions during the conversion coating process may result in pH decrease.

• Examples of conversion coatings include phosphating

Q5. How to cross verify 0.1 normality H2so4?
Ans. 
To cross verify 0.1 normality H2SO4, use a standard solution of NaOH and an indicator.
• Prepare a standard solution of NaOH of known concentration.

• Add a few drops of an indicator such as phenolphthalein to the H2SO4 solution.

• Titrate the H2SO4 solution with the NaOH solution until the endpoint is reached.

• The endpoint is when the indicator changes color, indicating that all the H2SO4 has reacted with the NaOH.

• Calculate the...read more

Q1. Circuit diagram of relay holding.
Ans. 
A relay holding circuit diagram is used to keep the relay in the energized state even after the control signal is removed.
• The circuit typically includes a holding contact that maintains the relay coil energized.

• A latching relay can also be used for holding without continuous power supply.

• Examples: ladder logic diagram with a holding contact, latching relay circuit diagram.
