Varroc Polymers Senior Officer Interview Questions and Answers

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

Detection and prevention poka-yoke refers to the use of techniques to identify and prevent errors in a process.

• Poka-yoke is a Japanese term for mistake-proofing

• Detection poka-yoke involves identifying errors as they occur

• Prevention poka-yoke involves designing processes to prevent errors from occurring

• Examples of poka-yoke include using checklists, color-coding, and physical barriers

• Poka-yoke can improve quality, reduc

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

To prepare 0.1 N H2SO4 & NaOH, calculate the required amount of solute and dissolve it in distilled water.

• Calculate the molar mass of H2SO4 and NaOH

• Determine the required amount of solute using the formula: N = (W/M) x (1000/V)

• Dissolve the calculated amount of solute in distilled water to make 1 liter of solution

• Standardize the solution using a primary standard

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

Prepare a pH buffer solution as per defined standard in tablet.

• Filter the solution and store in a clean container

• Use a calibrated pH meter to verify the pH of the solution

Poka yoke is a Japanese term for mistake-proofing. It is a technique used to prevent errors in a process.

• Poka yoke involves designing a process or product in a way that prevents mistakes from occurring.

• Examples of poka yoke include using color-coding to differentiate between similar parts, using sensors to detect errors, and designing products with only one way to assemble them.

• Poka yoke can improve efficiency, reduce ...read more

Process capability is the ability of a process to produce output within the specification limits.

• Process capability is a statistical measure that compares the variability of a process output to the specification limits.

• It helps to determine if a process is capable of producing products that meet customer requirements.

• Process capability is usually measured using indices such as Cp, Cpk, Pp, and Ppk.

• A process with a high...read more

Cp measures process capability, while Cpk measures process capability adjusted for centering.

• Cp is calculated using the formula (USL - LSL) / (6 * standard deviation), where USL is the upper specification limit, LSL is the lower specification limit, and standard deviation is the process standard deviation.

• Cpk takes into account the process centering and is calculated using the formula min((USL - mean) / (3 * standard d...read more
