Question:

I have recently been doing some research into the current methods used to clean conveyor chains and I-beams for the prevention of dirt falling onto parts, when I came across an abstract referring to a report released in the June 1999 Painting Clinic. I am currently working for a company in Australia, which manufactures play gyms for children, so surface condition and quality is our highest concern. I imagine you would be aware of the frustration with quality and production losses resulting from the dirt falling onto parts post-pretreatment and I was wondering how I could obtain a copy of that report or specifically that chapter? Thanking you in anticipation, P. M.

Answer:

In the June 1999 issue of Painting Clinic, I answered a question from M. D. titled “Dirt Problems.” He wanted to know some of the basics on how to control or eliminate problems of dirt falling onto products on a paint line.

In my answer, I told him that positive steps must be taken to eliminate dirt from falling on painted parts. Most of the dirt is from airborne contamination. The contaminants are drawn into the spray booth with make-up air. To completely eliminate these contaminants, the spray booth must be fully enclosed and the make-up air must be filtered. I have said before in this column that air borne contaminants can travel hundreds of feet in a factory. Another source of dirt is the conveyor. This can be corrected by using chain cleaners. The last but not least source of dirt is the paint itself. Paint should be filtered while pumping or pouring from shipping containers. There should also be filters in the line from the paint supply to the spray gun. It is important to note the other aforementioned sources of dirt that can fall on pretreated and painted parts in a paint line. If you are convinced the source of your dirt is the conveyor chain, suppliers of conveyor cleaning equipment are listed in the 2005 Products Finishing Directory and Technology Guide (www.pfonline.com/suppliers.html).
