苏青SQD-777是一种大孔苯乙烯系强碱阴离子交换树脂,因为具有专门设计的特殊孔结构,使得该树脂可以广泛应用于食品、医药、化工等领域多种物料的脱色处理。不但吸附量大,脱色彻底,而且再生容易,使用寿命长。根据不同用途的需要,可以提供多种粒度选择。
SQD-777 is a macroporous polystyrene-based strong anion exchange resin. Because of the specially designed pore structure, this resin can be widely used to remove colors of various materials from food processing, pharmaceutical and chemical industries, etc. This resin not only has very high capacities for color substances, but also has a high efficiency, and can be easily regenerated. The life time of this resin is also very long. According to different applications, several different particle size ranges are supplied.

树脂再生方法(Regeneration Method)
由于SQD-777脱色树脂使用范围广泛,用在不同领域的时候其再生方法可能会有不同。不过再生剂一般为盐酸、氢氧化钠和氯化钠,有时候需要一种,有时候需要多种组合联合使用。再生时适当加热(50-80℃)会对再生效果有一定的帮助。
Because SQD-777 color removal resin can be used in many areas, so that the regeneration method might be different for different applications. However, the regenrants used are usually HCl, NaOH and / or NaCl. Sometimes, only one kind of the regenerants is enough. Some other times, the combination of two or all three kinds of the regenrants might be needed. Usually, an elevated temperature (50-80℃) can result in a more efficient regeneration.
