中国钛白工业发展中几个问题的思索

论述了中国钛白工业发展中出现的几个问题，如：钛矿资源不足和采矿能力不足；高钛渣生产装置正在建设中，高钛渣尚未应用于钛白生产；钛白生产厂家过多，生产规模偏小；钛白行业对钛铁矿没有统一的标准等。提出在钛资源方面中国应在加大开采力度的同时，组织从国外进口；应建设高钛渣生产基地；应制定出钛白行业的钛铁矿标准；应建设热、电、化工、钛白联合企业等。     

Development of flexible organic light‐emitting diode on barrier film and roll‐to‐roll manufacturing

To come out with a successful organic light‐emitting diode (OLED) lighting business, it is very important to have clear differentiation of OLED from LEDs. Flexible OLED has merits, such as capability to be mounted on the curved wall, which is not easy for LEDs to achieve the feature. There are several approaches to make flexible OLEDs especially among those plastic barrier films that can bring high level of flexibility, which could not be achieved by any conventional lighting method. In this paper, barrier films with various water vapor transmission rate values, including 10^{? 6} order, are applied, and the conditions to have almost no dark spot growth under 85 °C and 85% high temperature/humidity test are shown. Flexible OLED panels are manufactured with the world's first roll‐to‐roll equipment using plastic barrier film.

六种药剂防治向日葵白锈病试验研究

六种药剂防治向日葵白锈病田间药效试验结果表明,25%甲霜灵WP1000倍、50%安克WG2500倍的防效分别为87.6%和86.8%,显著优于64%杀毒矾WP800倍(防效75.7%),而52.5%抑快净WG1000倍、72%霜疫必克WP600倍和80%乙磷铝WP600倍的防效相当,不理想,均未达到50%。经方差分析证明处理间差异达到显著水平。     

Development of a high‐resolution RGBW flexible display using a white organic light‐emitting diode with microcavity structure and that of a side‐roll touch panel

In this study, white organic electroluminescent devices with microcavity structures were developed. A flexible high‐resolution active‐matrix organic light‐emitting diode display with low power consumption using red, green, blue, and white sub‐pixels formed by a color‐filter method was fabricated. In addition, a side‐roll touch display was developed in combination with a capacitive flexible touch screen.     

利用钛白废酸制高纯度磷酸一铵试验简介

试验表明,用钛白粉生产中副产的w(H2SO4)≈20%的钛白废酸,经浓缩、净化及再稀释后与磷矿粉反应,在加入净化添加剂的条件下制得纯净的湿法磷酸与氨或碳酸氢铵反应,可代替热法磷酸为原料生产相同质量的高纯度磷酸一铵。分析了该工艺的技术可行性和经济可行性,认为所得的纯净磷酸也可加工成其他高纯度磷化工产品。     

新型细胞固定化载体强化白腐菌降解活性染料

为提高白腐真菌的产酶能力和后续对染料的降解效果,采用摇瓶试验研究新型细胞固定化载体——聚氨酯泡沫固定化白腐真菌后的锰过氧化物酶(MnP)产生情况以及后续对活性染料——活性艳红K-2BP的降解效果.结果显示,新型载体固定化培养白腐真菌的5d脱色率为95%,比悬浮培养7d的脱色率高15%.固定化培养产生的MnP酶活为936.61U/L,而悬浮培养的MnP仅为269.52U/L,并且酶活高峰期提前4d.另外,固定化培养体系中碳、氮源的消耗比悬浮培养快很多,而且固定化培养使得白腐真菌具有较高的H2O2产量.因此,新型细胞固定化载体强化白腐真菌降解活性染料的原因应归于这种培养体系碳、氮源的快速消耗而带来的MnP酶活的提高和高H2O2产量.     

超高压改性对鸡蛋蛋白液起泡及物理性质的影响

采用超高压改性鸡蛋蛋白液,研究了压力、保压时间对蛋白液起泡性质和物理性质的影响结果表明,新鲜蛋白液在350MPa的静水压下处理15min后的起泡性质最好．此外,超高压改性还导致蛋白液的黏度和表面张力呈现升高后又急剧降低的趋势,并能够降低蛋白液的明度.
