三思科技材料有限公司(sciencek)__纳米纤维素

我们引进了加拿大制造纤维素纳米晶的先进技术,采用硫酸水解木浆制备了纳米棒状纤维素结晶,并采用喷雾法干燥得到白色粉末。粉末状纤维素纳米晶可以很好地再分散到水中。

我们同时提供各种改性CNC,比如TEMPO CNC,具有pH,温度或者光响应的CNC,以及疏水的CNC等等。

We also provided a varity of modified CNC, such as TEMPO CNC, pH-, temperature-, light-responsive CNC, hydrophobic CNC, et al.

The CNC we provide is extracted from wood pulp by sulfuric acid hydrolysis. The CNC powder is spray-dried, and can be easily re-dispersed in H2O.

从木材到纤维素纳米晶 From wood to CNC

纤维素纳米晶的制备 The preparation of CNC

纳米纤维素的分类 The classification of nanocellulse

Cellulose is the main building block of trees and plants. Its nanocrystals are organized in a structure of strongly ordered crystalline particles which have been engineered by nature to be inherently strong.

A: Their size, shape and charge lead to unique behavior in solutions.

B: The high chemical reactivity of the surface1 makes CNC customizable for various applications.

C: Their heat stability allows high temperature applications.

CNC are not all made equal. The CNC we imported from Canada has specific properties and are especially easy to disperse. CNC can be modified and tailored to suit the specific needs in various applications.

过程 Process

The process begins with wood pulp produced from FSC certified sources as a raw material. The pulp undergoes a reaction process that removes the amorphous components, leaving high purity cellulose crystals intact. These crystals are then separated, cleaned and dried to form a powder material for shipment. We recycles the chemicals used in the production process, and converts sugars into energy, for reuse in the system.

the final spray-dried product to be easily dispersed at the end user location, leading to significant savings in the cost of storage and transportation. Depending on the application requirements, various product grades are available.

质量 Quality

The plant uses state of the art equipment and has rigid internal procedures to ensure CNC is of the highest purity and of consistent quality to meet the customer demands. CNC can be used in high end applications such as electronics. We are also a participant in the international standardization efforts being conducted by the ISO/TC 6/TG 1 Cellulosic Nanomaterials task group.
