Application Guidelines
Recommended Dosage
Wet membranes are typically designed based on membrane dimensions, thickness, dry-basis weight, or basis weight per unit area, rather than conventional addition percentages.
Application Method
The membrane can be used directly or loaded with functional components through impregnation or solution exchange, followed by subsequent composite processing or drying.
Pre-Treatment
Before use, the membrane may be washed with water, impregnated, subjected to solution exchange, or cut to the desired size, depending on the specific application requirements.
Precautions
Pay attention to membrane thickness, moisture content, impregnation time, and the uniformity of functional-component diffusion throughout the BC network.
Small-Scale Trial Recommendations
It is recommended to evaluate different functional-component concentrations and impregnation times, and compare liquid uptake, water retention, loading capacity, mechanical properties, and conformability.
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: Why does bacterial cellulose have a high water-retention capacity? How can it be evaluated?
A: BC consists of a continuous three-dimensional nanofibrous network that can retain a large amount of water within its interconnected pores. Its water-retention performance can be evaluated using parameters such as moisture content, water-retention capacity, centrifugal/pressure-induced water loss, and rehydration performance.
Q: What are the structural differences between BC wet membranes and plant-derived CNF membranes?
A: BC forms a continuous nanofibrous network in situ through microbial fermentation, whereas plant-derived CNF membranes are typically formed by casting or other membrane-forming processes from pre-dispersed nanofibrils. The two materials therefore differ in feedstock origin, network formation mechanism, and wet-state structure.
Q: What is the difference between BC membranes and conventional nonwoven facial masks?
A: BC wet membranes consist of a continuous nanofibrous network with a high water content, whereas conventional nonwoven facial masks are based on a different fibrous structure. As a result, the two materials exhibit different characteristics in terms of conformability, water retention, and functional-ingredient loading.
Q: What should be evaluated when BC wet membranes are used for facial mask or wound dressing research?
A: Key parameters include moisture content, water-retention capacity, liquid uptake, membrane thickness, wet-state mechanical properties, conformability, loading capacity, and relevant safety parameters. For end-use applications, the material and finished product must also comply with applicable regulatory requirements.
