AU-MTPE*0
Special Enzyme Used for
Chemi-mechanical Pulping and Long Fiber Pulping
Introduction:
AU-MTPE*0 is the special enzyme used for
chemi-mechanical pulping and long fiber pulping. It is extracted
from three special-effect enzymes and is suitable for the range of
pH 5.**8.0 and temperature *2**5 °C.
Based on its effects to fibers
in pulp, AU-MTPE*0 can make the fibers absorb adequate water and
expand and promote fiber brooming, so reduce the energy consumption
in the subsequent pulping process. Because the fibers absorb enough
water and are fully expanded, they become soft and thickening, and
increase the bulk and flexibility. At the same time, AU-MTPE*0 can
re-combine the fiber fines, which is conducive for water draining
of wet sheet, can reduce the fiber fines content in white water and
improve the recycling rate of white water, thereby reduce
consumption and clear water usage per ton primary pulp. AU-MTPE*0
has certain stripping roles to slime pulp adhered in the system,
long tome use can make the entire approach system of paper machine
more, avoid the paper flaw such as color spot and paper breakage
phenomenon resulting from slime pulp, reduce the cleaning frequency
of forming wire and blankets and prolong the life of forming wire
and blankets.
Advantages:
1. Polymerization
The polymerization can re-combine the fiber fines
in pulp. When AU-MTPE*0 bio-enzyme is added into the pulp, it
firstly meets with the fiber fines in the pulp. For its quantity is
countless times more than the fiber fines, the bio-enzyme can
surround the fiber fines and re-polymerize them together. When
these fiber chains collide with long fibers, they attached to the
long fibers; at the same time, due to the very small size of
AU-MTPE*0, when they are added into the pulp, even contact with
long fibers firstly, they will be bounced. However, after they are
re-combined with fiber fines and form larger sizes, together with
their own adhering property, they will re-combine with the long
fibers when encountered again in the last period. The advantages
derived from this characteristic of AU-MTPE*0 are listed as
follows:
a) To reduce the white water
concentration of paper machine, increase retention rate, reduce
consumption per unit pulp, increase production per unit time and
create benefits for enterprise.
b) The closed recycling water will
become clean, which can reduce the cost of water treatment or the
added amount of clear water and create benefits for
enterprise.
c) The paper strength of short fiber
parts will be increased, which can reduce the proportion of
high-quality raw materials and create benefits for
enterprise.
d) The drainability of pulp will be
significantly strengthened and the rotating speed of paper machine
will be increased, thereby increase the production or shorten the
available machine time.
2. Brooming Effect
AU-MTPE*0 bio-enzyme can directly effect on the
fiber surface and make the smooth fiber surface generate many fiber
branches, which plays the role of brooming. The advantages derived
from this characteristic are as follows:
a) Since the connection among the
fibers after brooming becomes multi-point connection, the tension,
break-resistance and tearability of finished paper are all been
increased. Together with the re-combination of fiber fines to the
fiber branches after brooming, the quality of paper is further
improved, which can increase the market competitiveness of
enterprise products.
b) Due to the improvement of
strength, the proportion of high-quality raw materials can be
reduced, which can create benefits for
enterprise.
3. Expansion of Water
Absorption
AU-MTPE*0 can loose the fiber
internal structure and make the fibers be easy to absorb water and
expand. Its advantages are as follows:
a) The fibers after expansion of
water absorption will be softened, which can save the energy
consumption for jordaning and create benefits for
enterprise.
b) To increase the bulk of finished
paper, that is, in the same amount the thickness of paper will be
increased, which can increase the market competitiveness of
enterprise products.
Based on the above effects,
enterprise can also reduce appropriately the beating degree of
jordaning without changing the quality parameters of finished
paper, which can reduce the energy consumption at the same
time.
4. Antibacterial Action and
Cleaning System
It has certain stripping effects to
slime pulp adhered in the system, long tome use can make the entire
approach system of paper machine more, avoid the paper flaw such as
color spot and paper breakage phenomenon resulting from slime pulp,
reduce the cleaning frequency of forming wire and blankets and
prolong the life of forming wire and blankets.
Taking all these advantages:
AU-MTPE*0 can make the pulp cleaner, improve the
whiteness of pulp, extend the life of paper blankets and at the
same time, can improve product quality, reduce energy consumption
and produce no pollution.
Characteristics:
Appearance: light brown powder
pH: 6.5 ± 0.3
Odor: faint fermentation odor
Density: 1.2 - 1.3 g/ml
Activity: ****0 clunit / gram + / -
5%
Effective temperature:
Optimum temperature: *0 - *0 °C
Effective temperature: *2 - *5 °C
Effective pH value:
Optimum pH value: 6.5 - 7.5
Effective pH value: 5 - 8

Conclusion:
AU-MTPE*0 will become ineffective
only when pH ≥ 9.5 or temperature ≥ *5 °C or concurrence of both.
If AU-MTPE*0 is ineffective, it usually can be found when paper
drying, also can be found in the produced paper that AU-MTPE*0 does
not have any effect.

bucket, the specific weight of the package may vary according to
user requirements.
Notice:
Avoid contact with skin and eyes. If leakage
occurred, wash with water. When taking AU-MTPE*0 from the barrels,
the tools shall be dry.
Storage:
If sealed and stored in cool and dry place, the
reduction of its activity will be no more than *0%. Seal after
use.
