(Fwd) painting problems
The following request was sent to me to forward to p2tech. We
discussed pressure reduction for the electrostatic wrap around
problem. Any other suggestions would be appreciated. You may post
replies to Jean Waters directly or to p2tech and I will forward.
Thanks in advance,

Subject: painting problems
Could you please help me find answers to the following painting
1) Filter disposal.
Two companies I visited recently soak their paint filters in water
and put them in a plastic bag before sending them to the landfill.
They claim there's no way to get the filters dry before disposal.
They have had fires in the dumpster when the filters are not soaked
in water. One company uses primarily xylene as a solvent, the other
uses primarily toluene.
Other than getting them to switch to another paint system, do you
have any ideas for avoiding soaking the filters? Two suggestions
I've considered are waiting until Monday morning to remove their
filters (rather than Friday afternoon) and hanging the filters from
racks outside the paint booth so they can air-dry before disposal.
2) gun efficiency
One company is using electrostatic guns to paint the
outside of cylinders. The cylinders range from about 1-6 inches
in diameter. There is alot of overspray. They said when they
adjusted their guns to get a smaller fan they couldn't paint fast
enough. They do paint a variety of parts. Sometimes they paint
big pieces of equipment in addition to tubes. My perception is
they're not getting much wrap currently. Any ideas on how to
encourage them? They have new, lightweight guns. How hard is it to
adjust the fan? Perhaps they could use a small fan for the small
tubes and adjust it bigger for the other equipment? They also can
have 3-4 color changes per day.
Thanks for your help,
