We would like to inform you about the Airfelt problems that occurred in
last days:
Blending Section:
- The mixed Fiber Quality: If we set the total weight > 5 kgs. per
drop, Bico and Cotton Fiber blend inhomogeneous.
- Zero weight button at 3.Blending works improperly.
Exel Section:
- Lot of dusts in filter bag.
- Fibers are too much open. (Previous Parameter 1.7 and 2 mm., now set
at 3 and 4 mm.)
Airfelt forming Section:
- Marc’s parameter can not use for production. We have to set new
Parameter:
Density must be between 20-30, MVEP should be 90.
If density is more than 30, a lot of dusts stay on surface.
If density is less than 20, the product weight swing (can not control)
If MVEP is less than 90, a lot of dusts stay on surface also.
- Bottom Side of product has Structure of metal conveyor belt, because
of pressed cylinder at steam oven. There is noise, if pressed cylinder
is over the product surface.
- Airfelt machine is very sensitive, with same parameter setting works
Machine sometimes.
( Case: a parameter Setting is set, machine does not start. We have to
increase K-Fact from 131 to 150, then machine let start, other parameter
are not changed)
- MRDN (%) runs from 0 – 60 (not stable). Fiber still run through
X-Ray, although MRDN is 0.
Cabinet Control:
- 3 Ventilators do not work, only 2 ventilator are still working
Supertrim Section:
- can not put trimmed material while airfelt is running
Filtration Section:
- Dust stick inside of cyclone, not falls in plastic bag.
- Pressure Switch at Filtration was short circuit since last week
