How to clean the melt flow index instrument after use

The melt flow indexer is a precision instrument used to measure the fluidity of plastics in a molten state. It is widely used in the fields of materials science, plastics industry and quality control. In order to maintain its test accuracy and extend its service life, cleaning after use is essential. The following are detailed steps for cleaning the melt flow indexer after use:

Take out the sample: After the test, wait for the barrel to cool to a certain temperature, use the ejector rod to eject the remaining sample from the barrel, take out the sample and place it properly.

Clean the die: Use special die cleaning tools, such as die cleaning needles, scrapers, etc., to carefully remove the residual material in the die. Be careful to operate gently to avoid damaging the inner wall of the die. For some difficult-to-clean material residues, you can use appropriate solvents for soaking and cleaning, but be careful to choose solvents that are not corrosive to the instrument, and wipe it dry with a clean cloth after cleaning.

Clean the barrel: Generally, a copper brush or a stainless steel brush is used, which is inserted into the barrel and rotated to remove the material attached to the inner wall of the barrel. For stubborn material residues, use a cotton ball or gauze soaked in solvent to wipe, but make sure that the solvent does not damage the barrel. After cleaning, blow the barrel dry with clean air, or use clean gauze to wipe it dry.

Clean the piston rod: Wipe the piston rod with a clean cloth to remove the material and oil on the surface. If there is material adhering to the piston rod, use a solvent to clean it and then wipe it dry. Make sure the surface of the piston rod is clean and smooth to ensure its normal operation and measurement accuracy.

Clean the outside of the instrument: Wipe the outer casing of the instrument with a damp cloth to remove dust and stains on the surface. For stubborn stains, use a small amount of mild detergent, but avoid the detergent flowing into the inside of the instrument. After wiping, wipe the outer casing of the instrument with a dry cloth.

Turn off the power: After all cleaning work is completed, turn off the power switch of the instrument and unplug the power plug.

Inspection and maintenance: Regularly check whether the various parts of the instrument are intact. If wear or damage is found, replace them in time. Perform necessary lubrication and maintenance on the instrument to ensure that it is in good working condition.

When cleaning the melt flow index meter, be sure to follow the instrument's instruction manual to avoid damage to the instrument due to improper operation. At the same time, the instrument should be regularly maintained to extend its service life and ensure measurement accuracy.
