现代织机发展到今日,已接近或达到了其实际极限。其根本的原因是目前的传统单相织机(singlephaseweavingmachines)是通过提高织机的运动速度来提高其生产能力的。高速开口和高速引纬不仅使织机本身受到接近极限的应力,而且纱线所受到的应... 相似文献

一、前言随着我国纺织工业在高支、高密和轻薄织物技术上的迅速发展,我国引进和自行开发研制了大量高、中档新型织机,如剑杆织机、喷水织机、喷气织机和片梭织机。现代无梭织机,只有在高质量纺织器材配套的前提下才能发挥效能。近年来我国先后引进了价格昂贵的德国舒伯力克(SPALECK)公司,日本木地金属筘制作所和高山钢筘公司制造的钢筘生产设备,虽然在钢筘制造上填补了部分空白,但由于大量的外汇支付,设备折旧,贷款利息使企业无法承受,妨碍了纺织器材行业的发展。国内现有的编筘机生产厂家制造的编筘机自动化程度和技术水… 相似文献

目前岩盐矿开采几乎都采用水平井对接连通工艺技术,即应用定向技术使水平井与目标直井对接连通,实现井组直接连通采卤生产.在水平井实施过程中,控制水平段井眼轨迹在盐层中的位置是十分重要的;当水平段井眼轨迹在盐层的中或上部时,则不能充分开采岩盐矿,井组的采卤流量和浓度也会不理想;因此应尽可能让水平段井眼轨迹位于盐层的下部,在单盐层矿区和地质条件复杂矿区则尤为重要. 相似文献

Influence of pectin modification on water binding properties 总被引:2,自引:0,他引:2
Water can be bound to food components and products as non-freezing, freezing-bound and free water. The interactions are crucial for any application as well as for food consumption and digestion. DSC was applied to examine the amounts of the different types of water bound to pectin, a biomacromolecule that is used as gelling and stabilising agent in many food products. One commercial high-methoxylated citrus pectin and three modified samples, prepared by acidic and alkaline demethoxylation as well as amidation, were tested. The water content of dry samples depended mainly on the molecular parameters, especially the content of hydrophilic groups at the galacturonic acid that was increased by demethoxylation and amidation, as well as on monovalent cations of the pectins. The water–pectin interactions of wetted materials were additionally influenced strongly by the availability of hydrophilic groups that depended on material properties such as amorphous or crystalline state, powder bulk and solid density and porosity as well as particle size, surface and porosity. Small amorphous porous particles, whose polar groups were rapidly available without prior softening and swelling, accelerated water uptake. Non-freezing and freezing-bound water, bound closely to the pectin molecules, depended on the number and type of polar groups. Free water, bound in micro- and macro-capillaries as well as voids within and between the pectin particles, was influenced by hydrophilic as well as hydrophobic groups of the samples. There was a strong impact of the pre-treatment during processing and modification. 相似文献

While charitable giving stagnates, Fair Trade and organic labelling as well as Cause-related Marketing campaigns are on the rise in Germany. The question as to whether the efficiency of the different systems is of relevance for consumers has received little attention in the literature so far. A latent class model for discrete choice analysis reveals five consumer segments with well distinguished preferences and willingness to pay measures for the modes of ethical consumption as well as for different donation amounts. For 27% of the 484 respondents ethical consumption occurs at the expense of other forms of ethical behaviour such as charitable giving. 相似文献
