介绍德国于利希中心的具有无溶剂环保特点的微乳液清洁剂
热度 2 Helmholtz 2014-4-4 16:04
德国于利希中心愿意向中国合作伙伴推荐一种具有无溶剂特点的微乳液清洁剂。合作方式为技术转让或许可生产。这个项目是成熟技术,德方已经向一个德国公司做技术转让,生产一种家用清洗画师油刷的专用清洗剂,另外,他们也相信这个清洗 剂比较适合用来擦洗中小学课桌上的油污、墨迹。 Technology_Offer_Mikroemulsion.pdf 微乳液 型清洁 剂的应用领域 和使用指南 应用领域 微乳液型清洁剂在一般情况下可作为传统溶剂型清洁剂的新型替代产品。 它适用于以下领域 。 1 。 建筑行业 的清洗: 粉刷 的清洁 (清除 掉半干的 溶剂型涂料 或半干的 水性涂料 ) 粘合物、胶 水的去除( 对化学类的双组份粘合剂或 瞬间粘合剂 只能 在非完全固化前予以清除) 硅胶或 聚氨酯 密封材料等密封材料 的去除, 也需要在非完全固化前予以处理 焦油和 沥青 为原料成分的产品 去除 2 。 家居领域 的清洁 剂。 -清污剂 -去除标签 -去除 重 油或 塑化 油或脂肪 的 污垢 -去除 胶带 残留物 3 。 工业清洗 。 -清洁 胶粘型涂料灌装 线 上的生产机械 … -去除 重 油、塑化 油或脂肪 类污垢 应用指南 微乳液型清洁剂通常比传统的溶剂型清洗剂的作用速度慢。 它需要较长的驻留时间,这是因为它相对于粘度很低的溶剂型的清洁剂其粘度有所增加。 为此在清除油漆 刷上的残余时需要更加彻底深入的 挤压 才便于去除 污垢 。 微乳液清洁剂中只含有低挥发性和非挥发性成分,这带来两个重要的 后果 : -容易保证较长的驻留时间,这适合于去除半干燥的油漆或粘合剂,适合大范围面积的应用。 可以在全开放环境下做到通宵甚至更长时间的浸泡清洗 -最后除去 清洁 剂的残留 须 要通过清水的漂洗。 Technology_Offer_Mikroemulsion.pdf Non-hazardous Microemulsion – an Alternative to Solvent Based Cleaners Innovation Scientists at the Forschungszentrum Jülich in Germany developed a microemulsion containing a special admixture and hence only very low amounts of surfactants. The big advantage of the microemulsion is that it does not have to be labeled. The microemulsion could be of interest for B-to-C and/or to B-to-B activities. It could be used as solvent-free brush cleaner in the Do-it-Yourself sector or in cosmetics. In the B-to-B field it could be used for cleaning industrial parts or as cutting and grinding fluid or hydraulic fluid. Technology Microemulsions are composed of two in principle immiscible liquids, usually water and oil, and one emulsifier preventing phase separation (surfactant). In contrast to normal emulsions microemulsions do not demulsify to their components, i.e. remain thermodynamically stable and appear to be transparent. The right choice of oils and surfactants has an effect on temperature stability and microstructures. At Forschungszentrum Jülich scientists were successful in formulating a microemulsion free of labeling. The patented microemulsion contains a special polymer allowing a considerably reduced content of surfactants (“booster”). Features  Removes water-based paint, varnishes, adhesives, silicone, acrylic sealant  Removes dirt on surfaces originating from resin and/or fat as well as stains from fabrics  Substitutes solvent based cleaners for example used for cleaning industrial parts, in household (e.g. baking oven cleaner) and in cosmetics  Not subject to labeling, not poisonous, not harmful to health, odorless  Stable over a wide temperature range (32°F-113°F and more)  Flash point 212°F  In essence devoid of volatile organic compounds (VOCs), permitting considerable time to react without the danger of evaporation of the emulsion  Low water pollution class providing advantages for transport and storage  Does not dehydrate but leaves a pleasant feeling on the skin  Economical formulation because water is the main component  Vegetable oil based and biodegradable  Composition may be modified and adjusted to new fields of application, use of other oils and surfactants may lead to different features Development status The microemulsion can be used everywhere where solvents are common today, for example for removing non-water-soluble remains and impurities (e.g. paint, adhesives). It is an interesting alternative to conventional solvent-containing cleaners which are harmful to the environment and health. Fig.1: Brush cleaner test with an off-the-shelf brush cleaner, containing large amounts of volatile solvents (photo 3, left) and a cleaner based on the microemulsion developed at the Forschungszentrum Jülich (photo 3, right). Patents European patent EP 1937795, filed on September 15, 2006, granted on June 01, 2011. European patent application EP 2253698, filed on September 15, 2006. Other patent applications, also in the United States, are in preparation. Application  Cleaning of industrial parts in fields still using solvents today (e.g. circuit boards, nozzles, stainless steel cannulas, automobile industry etc.)  Hydraulic oils, e.g. in fields requiring rigid fire protection (mining) or special environmental requirements (forestry)  Grinding and/or cutting fluids Next Steps Forschungszentrum Jülich is interested in licensing and/or RD cooperation.
