Performance Assessment of Nanocellulose Hydroxypropyl Methyl Cellulose Composite on Role of Nano-CaCO3 for the Preservation of Paper Documents 下载免费PDF全文
Deacidification and self-cleaning are important for the preservation of paper documents. In this study, nano-CaCO3 was used as a deacidification agent and stabilized by nanocellulose (CNC) and hydroxypropyl methylcellulose (HPMC) to form a uniform dispersion. Followed by polydimethylsiloxane (PDMS) treatment and chemical vapor deposition (CVD) of methyltrimethoxysilane (MTMS), a hydrophobic coating was constructed for self-cleaning purposes. The pH value of the treated paper was approximately 8.20, and the static contact angle was as high as 152.29°. Compared to the untreated paper, the tensile strength of the treated paper increased by 12.6%. This treatment method endows the paper with a good deacidification effect and self-cleaning property, which are beneficial for its long-term preservation. 相似文献

Abstract Mass transport properties of osmotic solutions are important in controlling osmotic dehydration process. In the first paper of the series “Mass Transfer Properties of Osmotic Solutions”;, data of water activities, osmotic pressure, osmosities or osmolalities and solute activities are presented. In the present paper, the literature data on diffusivities of both binary and multi‐component osmotic solutions are presented. Some aspects of measurement methodology and mass transfer modeling are also discussed. 相似文献

This work investigates the potential of developing a rapid test based on wicking of oil into paper for determining whether a reused frying oil is to be rejected. To achieve this goal, wicking patterns (oil penetration rate and oil front shape versus time) of both fresh and prolonged fried extra virgin olive oil are optically registered at six different paper stripes. Four of them are double-ply towel papers whereas the other two are single-ply chromatographic papers. Wicking tests are performed at 20 °C and 30 °C. It is shown that the type of paper affects seriously the wicking patterns. Double-ply papers present high oil penetration rates but very irregular oil front shapes whereas single-ply papers yield lower oil penetration rates but pretty flat oil fronts. Furthermore, it is found that only under certain conditions the penetration rates obey the well known Lucas–Washburn equation. A discussion is made on the phenomena that take place during wicking of oil into paper which may cause deviations from the Lucas–Washburn equation. A semi-empirical model is proposed to describe the above deviations by incorporating the effect of time evolving pore sizes. 相似文献
