Cationic Rosin Dispersion

Neutral Size Rosin can size paper in neutral conditions and facilitates the use of calcium carbonate as filler, thereby improving optical properties. Loss in brightness associated with acid sizing is efficiently controlled by Neutral Size Rosin.

LGS-P-NS20 is effectivesize for pulp stock in ph range 5.5 to 6 with Poly aluminium chloride (PAC)/alum as fixing agent.

LGS-P-NS20 is effective where water hardness is>100ppm. And suitable for fast sizing on high speed machine.

Advantages of neutral size over acid size :
Reduction in corrosion scaling/deposition.
Use of 15 to 20% calcium carbonate as filler.
Increased production due to smooth paper m/c run In absence of foam
Shade variation is drastically reduced.
Stronger, longer lasting sheet, improved brightness & printability.

Lipase is a biocatalyst widely used to catalyze esterification and transesterification. However, since the lipase is water-soluble and difficult to recycle and reuse, the powdery lipase is easily deactivated by being dispersed in an organic solvent, and the lipase is immobilized on an insoluble carrier, thereby improving enzyme activity and recycling. The use of macroporous adsorbent resin to immobilize lipase will make the active center of the enzyme more exposed, improve the catalytic activity of the enzyme, the catalyst can be reused, easy to separate, and the rosin ester is synthesized by immobilized lipase, which has mild reaction conditions and simple equipment requirements. High conversion rate and other advantages.
Suzhou Bojie Resin Technology Co., Ltd. provides macroporous adsorbent resin (lipase immobilization resin) to efficiently immobilize lipase, customer service problem of inactivation of free lipase powder in organic solvent, control of appropriate reaction temperature, reaction time and enzyme The amount can obtain the immobilized lipase with higher activity, can be reused after desorption, saves cost, increases the stability of lipase, and has broad application prospects.
