Bacterial proliferation issues

The use of water-based coatings has led some foundries to face problems related to coating pollution: bacterial erosion and degradation can affect the rheological properties of coatings, thereby affecting their application performance. In the robot immersion unit, the coating thickness may change due to the presence of bacteria. But its phenomenon is not obvious, and it is difficult to identify without an automatic measurement/control system, thus affecting the entire production process before you discover the problem.

Usually, foundries use chemical additives to prevent bacteria, but they can affect the rheological properties of coatings and may cause skin allergic reactions if operators come into contact with them.

ProService's solution

For this reason, it is not only necessary to implement good process management procedures, but also to adopt equipment and engineering solutions to reduce/prevent any risks related to this issue, such as:

·Install the disinfection system on the immersion tank and the coating preparation system CPP, apply it to the inlet pipe, and automatically disinfect before the water reaches the immersion tank.

·Design the contact area between the equipment, air, and operators (potential sources of infection) as small as possible.

·The production of coatings usually does not match the actual consumption of coatings. Most foundries prepare coatings in quantities greater than actual needs (coating consumption) in order to meet future production needs. Therefore, coatings have been working in their "aging" effect. The ProService system only continuously and automatically prepares new coatings when they are consumed, with only a small amount of solvent and coating raw materials added.
