Cationic Rosin Size LSR-35
The cationic rosin size is made with the international advanced
technique of high-pressure homogenization.Particle diameter in its
emulsion is even and its stability is good.It is particularly
suitable for cultural paper and special gelatin paper.
Appearance: milky white liquid
Solid content: 35% ± 2
Particle diameter: 0.2 ~ 0.7 μm
Viscosity: ≤ 25cps (25 °C)
P H value: 3-4
Zeta potential: +24-29 mv
Disperstiveness : easily dispersed in cold water
It can be used directly,or diluted to 3 to 5 times with clarified
water.Recommended adding point is before fan-pump and rosin size is
continuously added in by metering pump.Or rosin size can be added
with aluminium sulfate at the point after the pressure screen and
the adding amount is 0.3-1.5% of the absolute dry fibre.Retention
agents such as aluminium sulfate can be added in at the same
position or the mixing chest or machine chest.Sizing pH is
controlled at 4.5-6.5 and pH of white water under the wire is
controlled at 5-6.5.
The cationic rosin sizing agent has positive charge itself, so it can stay with the paper pulp,
declining the demand of Al2(SO4)3. And it can be used when the PH is 4.5~6.5, with CaCO3 as the padding. By using our cation rosin sizing agent, can not
only reduce the usage and get strong paper but also can reduce the
water pollution and the corrosion of equipment. Even in summer, it
can use as usual.
Packed in plastic drums with capacity of 200 Kg or 1000Kg.
