WET END PAPER APPLICATION
Since last decade, wet end process in
paper making preparation has become more complex. Some processes have
been developed to enable the use of calcium carbonate such as the acid
sizing system, pseudo neutral and neutral systems. The use of higher
filler contents are demanded in many paper grades.
Speeds of machine are increase, the head
boxes and wires have been drastically modernized. Due to this
situation, PT. SSI has produced two series of modified starch to achieve
cost reduction and improve quality of paper properties in paper production; SOLSACAT series and SOLSACAT – CS series.
SOLSACAT series is modified starch which is produced using AVEBE technology, and also known as AMYLOFAX T series.
SOLSACAT series/ AMYLOFAX T
series can be improved some parameter of paper such as to increase its
internal strength properties as well as retention of fillers &
fines. Advantages
a). Excellent Surface Strength
b). High performance at low integral costs
c). Faster drainage
SOLSACAT – CS series is a recent innovation
of modified tapioca starch which be developed by PT. Starch Solution
Internasional, used for widely spread over many applications in non-food
industry e.g. used as a thickening agent in a construction material
based upon gypsum or cement; used in the textile industry as component
for ink; as a thermo stable drilling fluid for the oil industry;
suitably be used in paper sack adhesive and for improving retention
paper application especially paper machine which have higher speed.
SOLSACAT- CS is
a higher molecular modified tapioca starch which be designed to enhance
drainage, retention, dry strengths in paper application. A higher
molecular weight corresponds with a higher binding power. This starch
suitable for both acid and neutral paper making condition, entrapped
until 60% in the paper web, interacts with paper fiber in a way that
there’s an overall improvement in drainage and first pass retention of
fines and fillers.
SOLSASPRAY is a spray starch with low temperature gelatinizing, used as adhesive in Ply bond or Multi layer board paper.
SOLSASPRAY is also
used as an internal bonding strength improvement for spray application
to paper substrates and for Ring crush strength improvement. This
technique which is intermediate between wet end addition and surface
sizing is an economical way to enhance the strength of paper.
