离子交换树脂在现代制糖工业中起着很重要的作用。世界上许多糖厂制造精糖和高级食用糖浆,多数使用离子交换树脂将糖液脱色提纯,而过去传统用骨炭的精炼糖厂亦有逐渐转向使用离子交换树脂的趋势。
Ion exchange resin plays an important role in the modern sugar industry. Many sugar factories in the world make refined sugar and high level sugar syrup, most of which use ion exchange resin to decolorizing the sugar solution. In the past, the traditional sugar refinery with bone charcoal has also gradually turned to the trend of using ion exchange resin.
离子交换技术有相当长的历史,某些天然物质如泡沸石和用煤经过磺化制得的磺化煤都可用作离子交换剂。但是,随着现代有机合成工业技术的迅速发展,研究制成了许多种性能优良的离子交换树脂,并开发了多种新的应用方法,离子交换技术迅速发展,在许多行业特别是高新科技产业和科研领域中广泛应用。近年国内外生产的树脂品种达数百种,年产量数十万吨。
Ion exchange technology has a long history. Some natural substances such as zeolite and sulfonated coal produced by sulfonation of coal can be used as an ion exchanger. However, with the rapid development of modern organic synthetic technology, many kinds of ion exchange resins with excellent properties have been developed, and a variety of new application methods have been developed. The technology of ion exchange has developed rapidly, and has been widely used in many industries, especially in high and new technology industries and scientific research fields. In recent years, hundreds of varieties of resin have been produced at home and abroad, with an annual output of hundreds of thousands of tons.
在工业应用中,离子交换树脂的优点主要是处理能力大,脱色范围广,脱色容量高,能除去各种不同的离子,可以反复再生使用,工作寿命长,运行费用较低(虽然一次投入费用较大)。以离子交换树脂为基础的多种新技术,如色谱分离法、离子排斥法、电渗析法等,各具独特的功能,可以进行各种特殊的工作,是其他方法难以做到的。离子交换技术的开发和应用还在迅速发展之中。
In industrial applications, the advantages of ion exchange resin are large processing capacity, wide decolorization range, high decolorization capacity, can remove a variety of different ions, can be regenerated and used repeatedly, long working life, low operating costs (although a large cost of input). A variety of new technologies based on ion exchange resin, such as chromatographic separation, ion rejection and electrodialysis, have their own unique functions and can carry out a variety of special work, which is difficult to do by other methods. The development and application of ion exchange technology is developing rapidly.
离子交换树脂的应用,是近年国内外制糖工业的一个重点研究课题,是糖业现代化的重要标志。膜分离技术在糖业的应用也受到广泛的研究。
The application of ion exchange resin is a key research topic in the sugar industry at home and abroad in recent years. It is an important symbol of the modernization of sugar industry. The application of membrane separation technology in sugar industry has also been extensively studied.
