Application Guidelines
Recommended Dosage
For paper, packaging, and biobased composite applications, an initial addition level of 0.2–2 wt% is recommended.
Addition Method
Pre-disperse the material thoroughly before incorporating it into pulp, fiber slurries, water-based polymers, or biobased composite systems.
Dispersion Method
Mechanical stirring or high-speed shear mixing is recommended. When blending with other fibers, ensure uniform distribution throughout the system.
Precautions
The bamboo-derived designation refers to the raw material source and does not imply specific surface functional groups. Actual dispersion behavior and surface charge should be determined based on the specifications of the specific product grade.
Small-Scale Trial Recommendations
For initial evaluation, focus on dry and wet strength, film-forming performance, barrier properties, and overall appearance of the resulting paper or film.
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 bamboo-derived CNF and wood-pulp-derived CNF?
A: The primary difference lies in the raw material source. In addition, the manufacturing process can affect fiber dimensions, crystallinity, surface chemistry, and final performance. Therefore, performance should not be assessed solely based on whether the CNF is bamboo-derived.
Q: How should the dimensions and surface functional groups of bamboo-derived CNF be characterized?
A: TEM or AFM can be used to characterize the dimensions of the nanofibrils. Depending on the specific preparation process, techniques such as FTIR, zeta potential measurements, and quantitative functional group analysis can be used to evaluate the surface chemistry.
Q: Is bamboo-derived CNF suitable for papermaking and biobased packaging?
A: Bamboo-derived CNF has a solid basis for application research and can be evaluated for paper reinforcement, biobased films, and packaging composites. Actual performance should be validated based on the pulp type, addition level, and processing conditions.
Q: What is the typical addition level for bamboo-derived CNF?
A: For paper, packaging, and biobased composite applications, an initial loading gradient of 0.2–2 wt%, based on the dry weight of the matrix, can be evaluated. The loading can then be optimized according to reinforcement, drainage, film formation, and processing performance.
