Application Guidelines
Recommended Dosage
For preliminary trials, a dosage of 0.5–5 wt% based on the dry weight of the matrix is recommended.
Addition Method
For aqueous systems, the material can be pre-dispersed and then directly incorporated into polymers, pulp, coatings, or bio-based composite systems.
Dispersion Method
Mechanical stirring or high-shear mixing is recommended. Moderate ultrasonication may be used when necessary.
Precautions
The lignin component may affect the color, interfacial properties, and optical performance of the final material. Preliminary compatibility and performance testing is recommended for light-colored or highly transparent systems.
Preliminary Trial Recommendation
It is recommended to focus on comparing reinforcement performance, color, UV shielding performance, and interfacial properties of the composite material.
Packaging and Transportation
Available in gram-scale samples, kilogram-scale trial quantities, and bulk orders of one metric ton or more, meeting procurement needs at different stages, including research and testing, pilot-scale validation, and industrial-scale applications.
Samples are supplied in sealed packaging and are preferably shipped via international express delivery. Please contact our customer service team for an international shipping quotation when placing an order.
For kilogram-scale and larger quantities, packaging options such as drums, large drums, or IBC totes are selected according to the product form and order volume, with an appropriate logistics and transportation method arranged accordingly.
FAQ
Q: What is the difference between lignin-containing CNC and conventional CNC?
A: Lignin-containing CNC retains a certain proportion of lignin-related components. In addition to the inherent reinforcing characteristics of nanocellulose, it may exhibit different color, surface chemistry, UV absorption, and interfacial properties.
Q: How does lignin affect the dispersion and optical properties of nanocellulose?
A: The lignin content and distribution can alter the surface chemistry, hydrophilicity/hydrophobicity, and color of the material, which may affect dispersion stability, transparency, and UV absorption. Evaluation should therefore be based on characterization of the specific batch.
Q: Is lignin-containing CNC suitable for bio-based packaging and functional films?
A: Yes. It can be evaluated for bio-based composites, packaging materials, functional films, and UV-shielding applications. For light-colored or highly transparent applications, color and light transmittance should be evaluated in advance.
Q: What properties should be prioritized when using lignin-containing CNC in composite materials?
A: It is recommended to evaluate dispersion stability, reinforcement performance, interfacial morphology, color, UV-shielding performance, and water absorption/water resistance in parallel to assess the overall effects associated with lignin retention.
