In papermaking, pre-flocculation of fillers such as ground calcium carbonate (GCC) improves the tensile strength paper sheets. However, pre-flocculated mostly suffer from instability floc shape decrease in diameter with time elapse after preparation and no improvement bulk stiffness. The addition compounds oxide or hydroxide to GCC, injection carbon dioxide caused GCC flocs be covered newly for...

one of the main issues of nanotechnology is producing materials with new properties. nanotechnology, as a powerful tool, has the ability to create evolution in the agricultural system and food–medicinal industries across the world. producing a high-performance material from reclaimed cellulose material will increase motivation to recycle these materials at all phases of paper production and rem...

Paper, which is in fact a very complex cellulose-based product derived from different lignocellulosic resources, usually regarded as simple omnipresent commodity our lives. Wood fibers trees are the most employed sources for papermaking purposes. From an environmental protection perspective, and their essential role life (they give us itself through foliar system supporting photosynthesis proce...

The origin of Tibetan papermaking is poorly documented. Up to now, only the paper fragments from Endere and Dunhuang sites have been scientifically studied outlining basic knowledge about plant fiber uses artwork manufacturing procedures. In order deepen on unique ancient papermaking, we report here analysis a set Samye Monastery in south Tibet, China. Multidisciplinary scientific investigation...

A fast analysis method with an online sample enrichment technique for the analysis of resin and fatty acids present in papermaking process waters was developed. This method was based on atmospheric pressure chemical ionization (APCI) and mass spectrometry (MS) for the detection of [M-H]ions of compounds of interest. The method was applied to the control of the most prevalent resin (dehydroabiet...

The papermaking industry can benefit a lot from nanotechnology. This versatile technology can also be used in the area of fillers for papermaking wet end applications. In such applications the main technological examples currently available include wet end addition of commercially available nanofillers, formation of nanofiller/fiber or nanofiller/fibril hybrids, development of novel categories ...
