Nano-filters are made from nanocellulose that is furled in a sheet of several layers. Nanofilter rolls (modules) are made of paper with a large suction capacity that is based on nano-cellulose and has very good properties compared to conventional industrial filters. They are biobased and biodeg...
The method comprises soaking raw material in a mild NaOH using reduced temperatures and pressures, and refining the material with a plate refiner so that a waste water stream is reduced in volume and has a pH within a range of 8 to 9. The present invention also comprises a HRC gel having...
HEPA filters used to separate airborne radioactive wastes must not be inflammable. This particular safety requirement is met with almost ideally by HEPA fi... F Becker,RE Kratel - pp 209-14 of Treatment of Airborne Radioactive Wastes. Vienna, International Atomic Energy Agency, 1968. 被引量:...
A filter aid and a method of using the same are disclosed that effectively removes contaminants from water-based metal forming liquids used in aluminum forming, rolling and other metal working processes. The filter aid includes a cellulosic material and a cationic polymer flocculating agent that is...
Although the two types of filters had no significantly different influ- ence (P > 0.05) on analyte recovery, the cellulose filter broke frequently during... H Liu,X Li,XS Wang - 《Plant Methods》 被引量: 158发表: 2012年 In vivo embryo production in buffalo: present and perspectives Buffal...
Self-contained Pod filters protect operators from exposure to biohazards Robust construction is easy to use and set up Smaller footprint facilitates use in tight spaces 規格 Filter Grade: A1HC Per 24 hour soak in 10 L pure water post autoclave (1 cycle of 60 minutes at 123 °C) and pur...
MicroCT, the parameters used for the digitalisation of the samples were: a step of 0.6 degrees around the medio-lateral axis, an acceleration voltage of 50 kV; a beam current of 800 µA; an exposure time of 4000 ms; a pixel size of the image of 14 µm; and no filters were ...

with a sulfuric acid catalyst. The resultingcellulose acetateis dissolved in acetone and spun into fiber through a dry spinning process. The application ofcellulose acetate fiberis limited to cigarette filters only and it accounts for about 2% of the total market for cellulose fiber (Banks, 2011)...
For cellulose acetate, there are several applications, such as in fibers, plastics, photographic films, and filters for cigarettes, among others (Steinmeir, 2004; Edgar et al., 2001). View chapterExplore book Bio-based resins for fiber-reinforced polymer composites ...
