充分了解EDTA的特性及产品用途

发布来源:http://www.jinhao360.com    更新时间:2022-08-05 点击数:

EDTA常温常压下为白色粉末,能溶于氢氧化钠、碳酸钠及氨溶液中,能溶于沸水,微溶于冷水,不溶于醇及一般有机溶剂。为了更好的使用它,下面跟着氢氧化钾厂家来充分了解EDTA的特性及产品用途吧。
EDTA is a white powder under normal temperature and pressure. It can be dissolved in sodium hydroxide, sodium carbonate and ammonia solutions, soluble in boiling water, slightly soluble in cold water, and insoluble in alcohol and general organic solvents. In order to better use it, let's follow the potassium hydroxide manufacturer to fully understand the characteristics and product uses of EDTA.
EDTA的特性
Characteristics of EDTA
EDTA是一种重要的络合剂。EDTA用途很广,可用作彩色感光材料冲洗加工的漂白定影液,染色助剂,纤维处理助剂,化妆品添加剂,血液抗凝剂,洗涤剂,稳定剂,合成橡胶聚合引发剂。
EDTA is an important complexing agent. EDTA has a wide range of uses. It can be used as bleaching fixative, dyeing agent, fiber processing agent, cosmetic additive, blood anticoagulant, detergent, stabilizer, synthetic rubber polymerization initiator for the washing and processing of color sensitive materials.
EDTA是螯合剂的代表性物质,能和碱金属、稀土元素和过渡金属等形成稳定的水溶性络合物。除钠盐外,还有铵盐及铁、镁、钙、铜、锰、锌、钴、铝等各种盐,这些盐各有不同的用途。
EDTA is a representative substance of chelating agent, which can form stable water-soluble complexes with alkali metals, rare earth elements and transition metals. In addition to sodium salt, there are also ammonium salt and various salts such as iron, magnesium, calcium, copper, manganese, zinc, cobalt and aluminum, which have different uses.
EDTA是一种优良的钙、镁离子螯合剂,用作乳液聚合所用水的螯合剂,除去Ca2+、Mg2+、Fe2+、Fe3+等金属离子。也用作厌氧胶的络合剂,即用EDTA处理甲基丙烯酸双酯,除去过渡金属离子,消除能促进过氧化物分解的影响,对提高厌氧胶稳定性的效果非常好。
EDTA is an excellent chelating agent for calcium and magnesium ions. It is used as a chelating agent for water used in lotion polymerization to remove metal ions such as ca2+, mg2+, fe2+, fe3+. It is also used as a complexing agent for anaerobic glue, that is, EDTA is used to treat the double ester of methacrylate, remove the transition metal ions, and eliminate the influence that can promote the decomposition of peroxides, which has a very good effect on improving the stability of anaerobic glue.

水处理方面的应用:
Application in water treatment:
EDTA具有广泛的配位能力,能与几乎所有的金属离子形成稳定的螯合物,而且其金属螯合物在微酸性条件下具有良好的溶解性,所以很早就在纺织行业中用做有害金属离子的抑制剂和水的软化剂。由于其金属离子螯合物的水溶性很好,在用水设备的清洗方面的研究和应用越来越多。
EDTA has a wide range of coordination ability, can form stable chelates with almost all metal ions, and its metal chelates have good solubility under slightly acidic conditions, so it has long been used as an inhibitor of harmful metal ions and a softener of water in the textile industry. Due to the good water solubility of its metal ion chelates, more and more researches and applications have been made in the cleaning of water equipment.
在农业上的应用:
Application in agriculture:
EDTA系列螯合剂的Cu、Ca、Fe、Mg、Zn等金属盐具有溶解性能好、易吸收等优点,成为微肥的良好来源,并且这些螯合态的金属盐相互混合后不影响其溶解性能,有利于作为多元复合微肥使用。而且EDTA有参与反应的羧基,可以生成钾盐、氨盐等,在补充微量元素的同时,补充钾肥和氮肥。对成本和效果进行综合考虑,它在很长一段时间内将会是螯合态微肥的首选,所以在我国的应用量也越来越大,应用范围也越来越广。
The Cu, CA, Fe, Mg, Zn and other metal salts of EDTA series chelating agents have the advantages of good solubility and easy absorption, and become a good source of micronutrient fertilizers. Moreover, these chelated metal salts do not affect their solubility after mixing with each other, which is conducive to the use as multi-element composite micronutrient fertilizers. In addition, EDTA has carboxyl groups participating in the reaction, which can generate potassium salts and ammonia salts, and supplement potassium fertilizer and nitrogen fertilizer while supplementing trace elements. Considering the cost and effect comprehensively, it will be the first choice of chelated micronutrient fertilizer for a long time, so it will be applied more and more widely in China.
EDTA系列螯合剂在照相、纺织、印染、造纸、日化、化学分析等方面也有广泛应用。另外要注意储存于阴凉、通风的库房,密封保存。运输途中应防曝晒、雨淋,防高温。更多相关内容就来我们网站http://www.jinhao360.com咨询了解吧。
EDTA series chelating agents are also widely used in photography, textile, printing and dyeing, papermaking, daily chemicals and chemical analysis. In addition, it should be stored in a cool and ventilated warehouse and sealed. During transportation, it shall be protected from sun exposure, rain and high temperature.
