Operation instructions and hints on dipping.
2.1. Before dipping, the products must keep clean and free from
static electricity.
2.2 the water surface must be clean, free from remains left from the
last dipping, expel the remains to the far end of the water tank with a
scraper,(or simply a wood piece).Expel gently and slowly, do not stir
the water or this may bring forth bubbles on water surfaces.
2.3 You have to distinguish the face side and reverse side of the
film, if you are not sure, touch with a wet finger to the film surface,
the sticky side is the face side and the face side must be laid on top
and the reverse side on bottom, don’t splash water on the film
spreading on water, the film must be spread evenly on water
surface,tryto remove the curved edge of the film with you finger,
remove the bubbles between the film and water with you finger by gently
expelling the bubble out of the film.
2.4Whn to start spray the activator?
Timing for spraying of activator is also a trick for successful
dipping, after the film laying on water, you,not only need to wait for
some time(1-2minuts,)you have to observe the film change as well, in 1
-2 minutes,the film is spreading flat with light glimmering, this is
the right time you apply activator, or you may make a small test.apply
a little activator one corner of the film .
How much activator spray to the film?
This is something of skill or experience , we just run the spray gun
crosswise from left to right and from top to bottom and then
lengthwise, also from left to right and from top to bottom, the sprayed
area between two passages may have 1/2overlap,never run repeatedly on
activated surface because this may disturb the pattern waves, do not
move the gun to fast or too slow.
2.5 Notes on dipping operation.
Make a trial dipping to ensure a successful dipping procedure:
2.5.1 Do not cut the film too big or too small, cut the size of the
just enough for dipping
2.5-2Dip the product to water at an angle about 30-40 degrees.to
water surface.
2.5-3Observe the wave direction especially the pattern of wood wave,
or you may decide to turn the film 90-180 degrees on water .the dipping
is a continuous one-step procedure, never stop lowering the product
down until it totally merged in water, any stop in middle of dipping
procedure will damage the pattern.
2.5-4When the product dropped to water, swing it gently in water and
take it, also in a tilted manner out from water surface without
touching the floating film remains, do not allow the product fall down
to bottom of the tank.
2.5-5Each time when you finished dipping, check if there is any
defect on the pattern (bubbles or cracks on the pattern, for
instance),this may give you idea for improvement on next dipping, if
the remains stick to the products , washing it away with water.
2.5-6The water in the tank must be maintained at certain level, in
WTP process , water is not only used as media to give pressure for
coating, it also washes way the remains , the water need to change if
you find the water is sticky or there are bubbles or lots of remains
floating on surface.
2.5-7 In normal operation, change water once a day and drain the
water from air dryer of the compressor once a day.
