纺纱、机织、针织设备的技术进步 总被引:1,自引:0,他引:1
四年一度的ITMA早已成为国际纺织界的盛会,它是展示新技术,拓展市场空间,树立品牌形象的大舞台。本届展会虽然缺少了一些知名企业的参与,规模上有所缩小,技术含量受到一定影响,但是参展企业依旧各尽所能,充分展示了各自企业和产品的风采。不少企业不惜重金购买了大面积的展位,并对展台进行了精心装饰;有的企业在展馆里搭台做起了时装秀,吸引了众多关注的目光;更多的企业则带来了最新的技术成果。透过熙熙攘攘的展会现场,我们力求从繁杂的展品中探寻最进几年纺织技术进步的痕迹。在纺纱、机织和针织三大领域,我们确实发现了许多值得关注的… 相似文献

In the context of global water scarcity and food security concerns, water footprints are emerging as an important sustainability indicator in the agriculture and food sectors. Using a recently developed life cycle assessment-based methodology that takes into account local water stress where operations occur, the normalized water footprints of milk products from South Gippsland, one of Australia's major dairy regions, were 14.4 L/kg of total milk solids in whole milk (at farm gate) and 15.8 L/kg of total milk solids in skim milk powder (delivered to export destination). These results demonstrate that dairy products can be produced with minimal potential to contribute to freshwater scarcity. However, not all dairy production systems are alike and the variability in water footprints between systems and products should be explored to obtain strategic insights that will enable the dairy sector to minimize its burden on freshwater systems from consumptive water use. 相似文献

Determination of Water Separation from Cooked Starch and Flour Pastes after Refrigeration and Freeze-thaw 总被引:4,自引:0,他引:4
A procedure for determination of net syneresis in starch and flour materials was developed based on free water in freshly cooked pastes, syneresis water expelled during cold storage and absorbed water in the contracted gel. Free water values decreased from 50% to <5%, as starch concentrations increased from 4 to 10%, indicating the need for correction of expelled+absorbed water values from free water for calculating net syneresis. Normal cereal, root and dicotyledonous seed starches exhibited a broad range of expelled water values during refrigeration, but gave high absorbed water values during freeze-thaw cycles. Waxy starches had low net syneresis during refrigeration and, except waxy corn, during freeze-thaw. For comprehensive evaluation, two refrigeration and two freeze-thaw cycles are recommended. 相似文献

黄原胶分子结构中含有大量的活性基团,在高吸水材料领域具有很好的应用前景。利用溶液聚合法制备了黄原胶杂化复合有机蒙脱土(XG-g-PAA/OMMT)的高吸水性材料,通过吸水动力学表明XG-g-PAA/OMMT的动力学扩散模型主要为non-Fickon扩散,说明XG-g-PAA/OMMT吸水过程中水分子的扩散速率与高分子链锻松弛速率相当。通过保水性研究表明XG-g-PAA/OMMT比传统高吸水性树脂的保水能力提高,能够有效的抑制水分的蒸发,且在沙土中恒温下的保水能力将获得增强。 相似文献

在全球和中国水危机的大背景下,企业和公民社会共同面临复杂多样的水问题。饮料企业属于用水密集型行业,水是最大宗的原材料,因此来自水的挑战尤其突出。由于很多风险源自外部,仅仅关注内部要素(例如生产线、工厂、办公室)并不足以消减与水相关的商业风险。富有远见的饮料企业将走出公司大门,把目光投向更广阔的领域,采取更加积极的态度和富有创新性的手段参与水管理。本文分析了饮料企业参与水管理的社会大背景、动机、尺度和方式以及注意事项。呼吁饮料企业探求一条既有益于商业目标同时又为社会添福祉的道路。 相似文献
