Nanocellulose纳米纤维素提取

Our range of versatile, very High Pressure Homogenizers (HPH) are an effective technique to delaminate the cell walls of cellulose fibers to liberate the nano-sized fibrils. Our technology also has advantages over other processing methods - learn more below.

Nanocellulose

Nanocellulose is nano-structured cellulose that has been extracted from the cell wall, from a cellulose source such as (e.g. wood pulp). Nanocellulose is also referred to NFC, MFC, CNF, and CNC (see end of page).

Nanocellulose has many important properties including high strength, excellent rigidity, low density, high surface area and rich hydroxyl groups which can be functionalized to various surface properties. Nanocellulose has multiple applications in many sectors including pharmaceutical, medical, material engineering and cosmetics.

Techniques for Nanocellulose Extraction

The main extraction methods can be categorized within these techniques - enzymatic hydrolysis, acid hydrolysis and mechanical processing including our own High Pressure Homogenization technology.

Nanocellulose and our High Pressure Homogenizers

Typically, a pre-prepared cellulose 'slurry' is pumped, at very high pressure, through a valve / vessel, which generates high impact and shear force in the fluid to delaminate the cellulose fibers in longitudinal axis, which results in the nanofibrillated cellulose. After several passes through this process particle sizes would typically be less than 50nm, several micrometers in length with good narrow particle size distribution. The post-processing product is a transparent aqueous gel.

Benefits of our class-leading Technology

Easy to scale systems capable in producing Nanocellulose gels at industrial scale.

Creating ultra-fine nanofibers whilst maintaining the original length.

Well dispersed fibers with exceptional strength properties.

Smaller particles sizes, with narrow distributions, when compared to other techniques.

Our unqiue technology, and slower pump speed, lessens the risks of solid accumulation in the homogenizer.

Ultra high pressures to 60,000 psi (4200 bar) and processing from Lab sample sizes to flow rates in excess of 1000 l/hour.

Verstatile, robust and controllable systems, with both piston gap and micro-channel processing options.

From Lab scale research to full production systems our Homogenizers can form the bedrock Nanocellulose based products.

纳米纤维素是从细胞壁提取的纳米结构纤维素，从纤维素来源如(如木浆)。纳米纤维素也被称为NFC, MFC, CNF和CNC(见页末)。

纳米纤维素具有高强度、高刚性、低密度、高比表面积和丰富的羟基等重要性能，可功能化成各种表面性能。纳米纤维素在制药、医疗、材料工程和化妆品等领域有着广泛的应用。

纳米纤维素提取技术

主要的提取方法可以分类在这些技术-酶水解，酸水解和机械加工，包括我们自己的高压均质技术。

纳米纤维素和我们的高压均质器

通常情况下，将预先制备好的纤维素'浆料'以非常高的压力通过阀门/容器泵送，这会在流体中产生高冲击力和剪切力，使纤维素纤维在纵向上分层，从而产生纳米纤维纤维素。经过几次这种工艺后，粒径通常小于50nm，长度为几微米，粒径分布较窄。后处理产品是一种透明的水凝胶。

我们领先的技术带来的好处

易于规模化的系统，能够在工业规模生产纳米纤维素凝胶。

在保持原有长度的同时创造超细纳米纤维。

分散良好的纤维具有特殊的强度性能。

与其他技术相比，粒径更小，分布更窄。

我们独特的技术，以及较慢的泵速，减少了固体在高压均质器中积累的风险。

超高压力达到60000 psi (4200 bar)，从实验室样品尺寸到流速超过1000升/小时。
