Bell cup/paint gun cleaner SL-2310U

A coating method called electrostatic coating is used in the coating process of automobiles. Electrostatic coating is a method in which the object to be coated (the car body) is positively charged and the paint is negatively charged to make the paint adhere to the car body.

A bell cup is attached to the paint outlet of the painting robot. As the name suggests, the cup is shaped like a bell.

This bell cup rotates at 5,000 rpm, and the centrifugal force and electrostatic force cause the paint to become fine and charged. The bell cup has many holes of a few microns in diameter, and the atomized paint (negative) is blown out and then attracted to the car body (positive), where it is applied.
Bell cups are often cleaned by soaking them in thinner, but once the paint inside the opening of the bell cup has dried, it cannot be removed because it is not soluble in thinner.
However, if the paint inside the bell cup opening dries, it cannot be removed because it is not soluble in thinner.
Therefore, in some cases, ultrasonic cleaners are used in combination with immersion in thinner during cleaning, but using solvents with low flash point (the flash point of common thinners is 9℃) in ultrasonic cleaners is extremely dangerous because of the risk of fire.

KAKEN TECH has developed the cleaning agents for bell cups, which not only have high cleaning power, but also have no flash point, so they can be used safely in ultrasonic cleaners.

High dissolving power
Strongly dissolves adhering paint that stays in minute areas and causes paint product defects.

Low VOC (Volatile Organic Compounds)
Compared to paint thinner, VOC (Volatile Organic Compounds) emissions can be greatly reduced.

No flash point
Since it has no flash point, it can be used in ultrasonic cleaners.

Troubleshooting for Painting process ~HAJIKI (cissing)~

HAJIKI (cissing) is a phenomenon in which a flowable paint comes into contact with a factor substance having a lower surface tension than that of the paint, and the factor substance spreads by being pulled by the paint, and the film thickness of the part becomes thinner.

Troubleshooting for Painting process ~BUTSU~

Defects due to particles tend to be more serious due to paint-induced particles, dust, fiber scraps, insects, other minute materials and also due to electrostatic adsorption due to static electricity. Therefore, it is necessary to grasp and observe the conditions of the surrounding environment in order to solve these problems.
