viscous liquid Cationic Pulp Chemical Dry Paper Strengthing Agent for newsprint Paper
TRADE NAME: Dry Strength Agent
|Appearance||transparent viscous liquid|
|Solid content, %||15.0±1.0||20.0±1.0|
|Viscosity, cps(25℃, cps)||3000-15000|
Dry Strength Agent LSD-20 can be widely used in papermaking of
packaging paper, household paper, newsprint, cultural paper and
It can effectively improve the paper folding strength, bursting
strength, stiffness, ring crush strength and so on.
On papermaking system with much anionic impurities or high
electrolyte concentration, the effect is particularly evident.
At the same time it has retention effect to flake fine and filler
can reduce the loss of fibers and linting and dusting phenomenon.
It can produce enough dry strength and allows the use of
inexprensive fiber or a higher proportion of secondhand fiber.
This is a kind of newly developed dry strength agent, which is a
copolymer of acrylamide and acrylic, it is a kind of dry strength
agent with amphoteric combo, it can enhance the hydrogen bonding
energy of the fibers under the acid and alkaline environment,
greatly improve the dry strength of paper (ring crush compression
resistance and bursting strength). Simultaneously, it has more
function of retention and sizing effect improving.
The dry strength agent is not only a good enhancement, but it also
has a higher enhancement effect in waste papers with more fine
fiber filler. The use of our dry strength agent can improve paper
quality, and it also significantly increase production efficiency,
reduce costs and increase economic efficiency.
Method of Application and Notes
1. When diluted with clean water, the dilution multiples of our
product is generally about 15 to 30 times. After the product was
stirred sufficiently, add uniformly to the slurry in an amount of 5
~ 10 kg / ton.
2. Adding position that selected could have a full contact with the
slurry. Generally choose ingredients pool, high box or import pump.
3. Use a plastic or stainless steel as the material for products
storage, dilution tank, piping etc.. Iron-based material will
produce corrosion and thickening phenomenon will occur.
4. Do not mix with other chemicals.
Dilution ratio: LSD-20 and water on 1:20-40, it may be added into
the middle of stock proportioner and machine chest, it may also be
continuously added with metering pump in the high level tank.
Adding quantity is 0.5-2.0% (generally speaking, is 0.75-1.5%,
virgin pulp (oven dry stock), adding concentration is 0.5-1%.
50kg/200kg/1000kg plastic drum.
Normally to be kept under sunshade to avoid direct sunlight, and it
should be kept away from strong acid. Storage temperature: 4-25℃.
Shelf life:6 months
