Overview :
LGS-P-CSS20 product boasts excellent film-forming ability. It can form a waterresistant layer on the surface of paper and cure rapidly, thus demonstrating agreat sizing effect. Besides, it has the benefits of small usage amount, lowcost, and it is easy to use, making it an ideal and wide application to writingpaper, packaging paper, wood-free paper, copying paper, coated art paper,high-strength corrugated paper, Kraftliner board and etc.
The product may replace partor all of internal sizing agent, hence lowering the cost of sizing. Itdemonstrates a great sizing effect after surface sizing. Since the sizing is maintainedon the surface of paper, the paper is thus endowed with excellent waterresistant property. The application of this product greatly improves thesurface strength and printability of paper, ensuring high fidelity, good gloss,dimensional beauty and significantly avoids picking, linting and pasting platein printing. It can be widely used in different surface sizing equipment. Whenused in conjunction with starch, excellent surface strength, stiffness andwater resistance can be ensured. The product also boasts great mechanicalstability and produces little foam, hence no antifoam agent is needed.

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. Properties : Appearance : milky-white dispersion Ionic Character : Anionic pH value : 6 to 6.5 Solid Content : 31 ± 1% Acid Number : 235mg KOH/g
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.
