For professionals in the paper industry, a comprehensive understanding of chemical products is essential for optimizing manufacturing processes and ensuring final product quality. NINGBO INNO PHARMCHEM CO.,LTD. provides a detailed Technical Data Sheet for its Cationic Rosin Size, a critical component in achieving superior paper properties. This document outlines the key specifications and performance indicators that guide its effective application.

The 'Appearance' of our Cationic Rosin Size is described as a Milky White Liquid. This visual characteristic is important for quality control and indicates the stable dispersion of rosin particles within the carrier liquid. The 'Solid content' is typically around 35% (±1%), signifying the concentration of active sizing agent in the formulation. A higher solid content generally means a more concentrated product, potentially requiring less volume for the same effect, which aligns with the 'less dosage, perfect effect' benefit.

The 'Ionicity' being Cationic is fundamental to its function. This positive charge allows the rosin particles to effectively bind with the negatively charged cellulose fibers in the pulp. This electrostatic attraction is key to the retention of the sizing agent on the fibers, a critical step for achieving effective internal sizing. The 'Particle diameter' being very fine, specifically 0.6 to 0.8 micrometers, is another crucial specification. Smaller particle sizes lead to a greater surface area, which enhances the dispersion and the uniformity of the sizing effect on the paper's internal structure.

The 'pH Value' of the Cationic Rosin Size typically ranges from 2 to 4. This acidic nature is important for its interaction within the papermaking system, especially when used with agents like aluminum sulfate (alum). 'Viscosity', measured at 25°C, is also specified, usually around 100 mPa.s. This parameter influences how the liquid flows and disperses, impacting its handling and application. A manageable viscosity ensures that the product can be easily pumped and mixed into the pulp slurry.

The 'Shelf Life' of 6 months indicates the period during which the product is expected to maintain its optimal performance under proper storage conditions. 'Deliver Time' of within 7 days for samples and longer for bulk orders reflects the logistical efficiency of NINGBO INNO PHARMCHEM CO.,LTD. in serving its clients. The CAS No. 8050-09-7 uniquely identifies this chemical substance, ensuring traceability and compliance with industry standards.

Understanding these specifications is vital for papermakers looking to optimize their use of cationic rosin size for paper and paperboard. By carefully considering the appearance, solid content, ionic charge, particle size, pH, and viscosity, manufacturers can ensure that they are leveraging the full potential of this advanced sizing agent to achieve superior paper quality, enhance paper printability, and maintain efficient production cycles.
