摘 要：用X射线光电子能谱仪（XPS）检测了不同条件下干燥的高岭土-胶乳涂料体系涂层的表面元素组成，对涂布纸涂层固化过程中胶乳发生迁移的时间进行了研究。XPS检测显示，不同温度干燥时，涂层表面的碳元素含量随着干燥温度的升高而明显增加，随着室温滞留时间的延长而显著降低。实验结果表明，在涂布纸涂层固化过程中，胶乳粒子的迁移主要发生在涂料施涂以后至涂料内部形成毛细管的这段时间，即当涂料仍处于液体状态的时候。
关键词：涂层固化；胶黏剂；迁移时间；XPS；表面元素组成

Abstract：Surface elemental compositions of model clay/latex coatings consolidated under various conditions were measured using XPS technique, in order to elucidate the moment when the migration of particulate latex relative to pigments during drying of colloidal suspensions takes place. The results showed that surface carbon content was higher for coatings dried at a higher temperature, and surface carbon content reduced greatly as delaying drying at room temperature. The observations provided evidence that latex migration mainly took place after coating application but before capillary formation, i.e., when the coatings were in liquid phase.

摘 要：通过Fluent的Realizable κ-ε湍流模型以及多重旋转坐标系（MRF）技巧,对高浓漂白塔底稀释区旋转的直形和纺锤形两种喷射管进行了正反向几种转速的数值模拟，并对其各个出口的核心速度进行了采集和分析，然后利用粒子图像测速仪（PIV）对该模型进行了验证。结果表明，直形喷射管反向旋转转速10 r/min左右时，其各个出口的速度差值较小；纺锤形喷射管在正向旋转转速50 r/min下，其各个出口的速度差值最小；低转速的旋转喷射管在这两种条件下均可以视为等速喷射。用Realizable κ-ε湍流模型以及MRF技巧对旋转喷射水管进行数值计算和分析是可靠的。

Abstract：Based on Realizable κ-ε turbulent model and MRF technique in Fluent, the two kinds of rotary spray tube such as straight and spindle ones were simulated under different forward and reverse rotating velocities, and the core velocities of each outlet were collected and analyzed. Then PIV system was used to validate the model. The results showed that the outflow velocity difference of the straight-type spray line is the smallest when the angular velocity is about 10 r/min with the reverse rotation. While for the spindle spray line, the outflow velocity difference is smallest when the angular velocity is about 50 r/min with the forward rotation. The sprays of rotary spray tube under low rotation speed can be considered as the constant velocity sprays in these two conditions. The numerical simulation results agreed with the PIV experiment data. So both Realizable κ-ε turbulent model and MRF technique are reliable and the calculated results are correct.

Abstract：The back trap mottle in the print of different kinds of paper such as color offset newsprint, art paper and single coated paper was evaluated in this paper. Results showed that the optimized conditions of two kinds of newsprint are as follows: ink amount 0.10 mL, printing pressure 650 N, printing speed 0.4 m/s; there exists inconsistent correlation between objective quantitative assessment of mottling and subjective evaluation. Less mottle is obtained with the least ink amount by means of objective quantitative assessment, however, less mottle results are obtained with the medium ink amount when using subjective evaluation. The optimized conditions of the two kinds of single coated paper are as follows: ink amount 0.35 mL, printing pressure 200 N, printing speed 0.3 m/s. The optimized conditions of art paper are different. Results showed that there exists consistent correlation between 2 groups and 4 groups subjective evaluation of mottling. Among the three objective analysis methods, spectrum analysis correlates most closely with the visual results, then the PTS method. And the grey value method correlates at the least. So the spectrum analysis and the PTS method are expected to be the new methods for evaluation of the back trap mottle.

摘 要：以荧光增白剂VBL为标准物质，结合荧光分光光度法和白度法对比检测纸张中荧光增白剂的荧光强度和可迁移荧光物质含量，对按GB/T 5009.78—2003食品包装用原纸卫生标准被判定为荧光不合格的纸产品进行进一步检测。结果表明，荧光分光光度法检测中，标准物质VBL在浓度0～4 mg/L 范围内，有较好的线性相关性，可迁移荧光物质含量在5～1055 mg/kg之间；而白度法测试显示，纸张表面的荧光亮度与可迁移荧光物质含量未必一致，两者存在差异。白度法虽然能够测试纸张表面荧光物质是否存在，但是无法反映可迁移荧光物质的情况，同时对于可迁移荧光物质含量在10 mg/kg以下的纸张，白度法灵敏度较低。

Abstract：17 samples in which fluorescence was not meet the regulation requirement based on the analysis following the analysis method for food packaging base paper hygiene GB / T 5009.78—2003 were tested furtherly. Fluorescence intensity and fluorescent migration were tested by fluorescence spectrophotometry and brightness instrument respectively, using fluorescent whitening agent VBL as the standard material. When the concentrations of VBL were from 0 to 4.0 mg/L，they had a linear relationship with the emitted fluorescence intensity. The experiments showed that different methods derived different results. The fluorescent migration may be affected by basis weight of the paper and the manufacturing process. The brightness method, which can be used to test the fluorescent substance in the surface of paper, can not reflect the migration of fluorescent.

Abstract：The elastic modulu and loss factor of diaphragm are closely related to the acouse characteristic of the loudspeaker. An ideal loudspeaker diaphragm requires higher elastic modulu and proper loss factor. In this work, the influence of paper cone grammage, beating degree of the pulp used for producing paper cone, and lamination structure of paper cone on dynamic mechanical properties of the paper cone was investigated. It was found that with the beating degree and basis weight increasing the elastic modulu of paper cone increased, while the loss factor showed an opposite trend. The lamination structure had an effect on the dynamic properties of the paper cone. Compared with the base paper, dry lamination derived higher density and loss factor and wet lamination derived lower density and higher loss factor. However, there was no significant change in elastic modulu whether dry or wet lamination method was used.

Results indicated that silk mask paper has higher filtering efficiency and desirable filtering resistance when the basis weight of silk paper is 45 g/m2 and the beating degree of silk pulp is in the range of 82°SR and 91°SR in this experiment. Furthermore, the loading of nano-TiO2 photocatalyst on silk paper effectively improves the antibacterial ability of the mask paper.
