A.
GENERAL PRODUCT INFORMATION
The product referred to in these instructions is a repair set that
can be used to repair Orfit vacuum bags.
B.
PRODUCT DESCRIPTION
The repair set consists of patches and paste that can be used to
repair small or medium sized damages, cuts or holes in the grey
and orange fabric of the Orfit vacuum bags.
The repair kit contains the following products: 1 tube of paste, 3
grey large foil patches, 3 orange large foil patches, 3 grey round
foil patches and 3 orange round foil patches.
C.
PRECAUTIONS FOR USE
•
Follow the instructions on the tube.
•
Always clean the surface around the repair area, e.g. with
alcohol. Dry the area with a dust-free cloth and let the
remaining moisture evaporate.
•
The applied paste may not be flattened. It will shrink when
curing. The initial height of the used quantity decreases to a
minimal thickness.
•
After the performed repair, the paste has to cure at least for
12 hours. This is especially important if the paste has to be
applied several times when repairing the weld seam.
•
Before the repaired article is put back into use, it must be
checked for leakage.
•
Any damages that exceed the mentioned dimensions have
to be repaired by Orfit.
•
Always use a surgical glove to prevent the paste from
sticking to your nails and fingers.
D.
METHOD OF APPLICATION
D.1. Cut of maximum 10mm long and cuts on the seam
–
repair WITHOUT foil patch
Small cuts or holes (e.g. by a needle) up to
10 mm in length
can
be repaired with the paste only without using a plastic foil-
patch.
Cracks or cuts that run along the weld seam cannot be repaired
with a piece of foil. Those cracks or cuts up to a length of
maximum 30 mm
can also be repaired with paste only.
If necessary, the paste must be applied several times. It should
be noted that the previously applied paste should harden
sufficiently before applying new paste.
Holes:
Squeeze a quantity of paste out of the tube around the hole to
build a round blot of approximately 15 mm in diameter and
approximately 3-4 mm in height. The hole should be in the
middle. (see the drawings below).
Cuts (maximum 10 mm in length):
Squeeze a portion of paste out of the tube around the cut to
build an oval blot. The blot should cover the cut 10 mm equally
around the cut and should be approximately 4-5 mm in height.
(See the drawings below).
D.2. Cut of maximum 50 mm long
–
repair WITH foil patch
The damaged area has to be cleaned extensively before the
repair with e.g. alcohol. Dry the area with a dust-free cloth after
cleaning. Let the residual moisture evaporate before starting
the repair. The damaged area should be smooth (no vacuum)
and the vacuum bag should rest on an even surface (no
wrinkles).
If the cut is
up to 50 mm
long, it is necessary to use a plastic
foil-patch. The foil-patch must overlap the cut by minimum 10
mm around the entire torn area.
Grey foil-patch
: Squeeze a portion of paste out of the tube
all
over
and
equally
on the coated side of the foil-patch. Do not
put the paste on the fabric side! Now put the foil patch centrally
over the torn area and press on it gently. Then add more paste
on the rim of the foil-patch to secure it entirely
Orange foil-patch
: Squeeze a portion of paste out of the tube
all over
and
equally
on one side of the foil-patch, either side
will work. Now put the foil patch centrally over the torn area
and press on it gently. Put a weight on top of the foil patch for 1
hour. Use a protection layer (e.g. wet wipe) in between the foil-
patch and the weight to prevent the weight from sticking to the
vacuum bag. After 1 hour add more paste on the rim of the foil-
patch to secure it entirely.
