Product
|
|
|
This
product is a
cooling accelerator
used in Kraft
pulping process.
By improving
the penetration
ability of AQ
and/or PS contained
cooking liquor,
it improves
cooking and
delignification
efficiency to
get higher pulp
yield and lower
chemical consumption. |
PD-1600
|
|
|
This
product is a
scale inhibitor
and scale dispersant
used in Kraft
pulping process
where heavy
scaling problem
occurs due to
the specific
high hardness,
high temperature
and high alkalinity
conditions in
the system.
It is effective
in inhibiting
calcium carbonate,
calcium sulfate,
and calcium
oxalate scales. |
PD-1800
|
|
|
This
product is a
defoamer used
in kraft pulping
process where
heavy foaming
problem occurs
due to high
concentrations
of salt and
surface active
substances (lignin,
extractives,
etc). Its dosage
is only 1/5
that of general
mineral oil
type defoamers
to have efficient
foam control
performance.
Being in ultra-micro
emulsion state,
it does not
affect the performance
of vacuum washers
while reduces
pitch troubles. |
PD-7700
|
|
|
This
product is a
peroxide stabilizer
employed in
peroxide bleaching
of pulps. By
effectively
inhibiting metal
ion activities,
it reduces peroxide
consumption
while improving
brightness results. |

E.
Oxygen bleaching
accelerator
|
This
product is an
oxygen bleaching
accelerator
used in oxygen
bleaching of
Kraft pulp.
As a special
nonionic surfactant,
it accelerates
the diffusion
and penetration
speed of oxygen
and alkali to
increase delignifying
and bleaching
efficiency,
meanwhile, it
improves pulp
quality and
helps obtain
higher pulp
yield. |
