ANTISTICKIES: BLUEMATE 880
Bluemate 880 is a multifunctional deposit control agent for process
waters.
It stabilizes pitch and stickies emulsion preventing their deposition on
clothing and machine surfaces.
Bluemate 880 is composed by natural components and it is
environmentally friendly.

BATCH DOWN one products are applied at high
concentration during paper
machine shut down
BATCH – ON-THE-FLY one or two products are applied in
a shock way with a special
equipment

CONTINUOUS CLEANING New concept
The chemicals are dosed into high
pressure lines
No special equipment is
needed Cleaning and dispersant action is
obtained
The clothing performances are
stable
No influence on the process water

FELT AND WIRE PASSIVATION
With passivation a thin chemical layer is created on the formic fabric or
on the press felt.
This chemical layer avoids the deposits if substances on the clothing
surface.
The passivation is the best treatment when deposits are on the surface
and not into the surface.

Passivation program could be:
Cationic (ACQ 702, ACQ 702 C,…)
Non ionic (WTC 709)
The product is dosed into conditioning shower water of the forming
fabric or of the felt press

WIRE PASSIVATION: WTC 709
WTC 709 applied only on half
forming fabric.
In the picture is possible to
see the reduction of stick
deposits.

DRYER FABRIC CLEANING: ACQ 707
It is a highly effective detergent,
solvent based built with
complex wetting agents.
It cleans the fabric surfaces of
any kind of organic deposits
It reduces the standard
cleaning time.
It doesn’t have typical solvent
smell

WIRETEC TECHNOLOGY
Alpha chemicals has focused its research to formulate a very effective
specific chemicals to reach the dryer cylinder or the dryer fabric cleaning
aims
WTC 716-718 for dryer cylinder
WTC 714 for dryer felt
WTC product is applied with a special dosing systems to reduce at the
minimum level the water needs and the possible aerosol formation. Its
application doesn’t change the paper humidity content and increase the
dryer section efficiency, reducing steam consumption
