The global shift towards sustainability has significantly increased the use of recycled fibers in the papermaking industry. While this is an essential environmental step, it presents a significant technical challenge: the management of 'stickies'. These tacky substances, originating from adhesives, coatings, and inks in waste paper, can agglomerate and deposit on machinery, leading to operational disruptions, reduced efficiency, and compromised final product quality. NINGBO INNO PHARMCHEM CO.,LTD. is proud to introduce a highly effective solution: our Stickiness Removal Enzyme.
Our Stickiness Removal Enzyme is a state-of-the-art, light brown liquid formulation specifically engineered for stickiness control in paper mills utilizing recycled pulp. It is a multiple enzyme preparation with high activity levels (greater than 100,000 u/ml), designed to work efficiently within the existing papermaking process. By targeting the root cause of stickiness, our enzyme offers a proactive approach to a persistent industry problem.
Mechanism of Action
The primary culprit behind many stickiness issues is polyvinyl acetate (PVAc), a common component in glues and adhesives. Our enzyme works by catalytically hydrolyzing the ester bonds within PVAc. This biochemical reaction breaks down the large, tacky polymer into smaller, water-soluble, and non-tacky components, primarily alcohols. These hydrolyzed substances disperse harmlessly in the process water and can be easily removed with the paper sheet, effectively preventing them from agglomerating into larger, problematic particles. This process is known as surface passivation, which reduces the overall viscosity and adhesive potential within the pulp slurry.
Benefits and Applications
Implementing our Stickiness Removal Enzyme brings a multitude of advantages:
Improved Machine Runnability: By preventing the deposition of stickies on wires, felts, and rollers, the enzyme significantly reduces the frequency of machine cleaning and downtime.
Enhanced Paper Quality: It leads to a cleaner final product with fewer specks, holes, and other defects caused by stickies, improving the paper's strength and appearance.
Increased Chemical Efficiency: The enzyme helps to reduce the anionic trash in the system, which can interfere with positively charged chemical additives like retention aids and sizing agents, thereby improving their performance.
This versatile enzyme is suitable for the production of a wide range of paper products, including:
Usage and Recommendations
For optimal performance, we recommend adding the Stickiness Removal Enzyme before the pulper or at the pulper ramp pump. The typical additive amount is between 60 to 150 grams per metric ton of absolute dry pulp. The enzyme is effective in a pH range of 5-8 and requires a processing time of over 30 minutes to ensure complete reaction. It performs well in pulp consistencies from 3.5% to 15%.
