Overview
D301FC macroporous weakly alkaline anion exchange resin uses saturated saline solution, which is approximately twice the volume of the treated resin. Soak the resin in the saline solution for 18-20 hours, then drain the saline solution and rinse with clean water to ensure that the discharged water does not turn yellow; Next, use a 2% -4% NaOH solution with the same amount as above, soak in it for 2-4 hours (or perform a low flow cleaning), drain the alkaline solution, and rinse the resin until the discharged water is close to neutral. Afterwards, use a 5% HCl solution with the same amount as above, soak for 4-8 hours, drain the acid solution, and drift with clean water until neutral

6、 Usage: Mainly used for the preparation of pure water and high-purity water, used as a pre bed or double bed in combination with strong alkali anion resin, which can significantly improve the economic efficiency of operation. This product is also used for the treatment and recycling of electroplating and chromium containing wastewater.
The density of resin when dry is called true density. The weight per unit volume (including the gaps between particles) of wet resin is called the apparent density. The density of resin is related to its crosslinking degree and the properties of its exchange groups. Generally, resins with high crosslinking degree have higher density, strong acidic or strong alkaline resins have higher density than weak acidic or weak alkaline resins, and macroporous resins have lower density. For example, the true density of styrene gel type strong acid cation resin is 1.26g/ml, and the apparent density is 0.85g/ml; The real density of acrylic gel type weak acid cation resin is 1.19g/ml, and the apparent density is 0.75g/ml.
(3) Solubility of resin
Ion exchange resin should be an insoluble substance. However, substances with low polymerization degree and substances generated by resin decomposition that are mixed in during the synthesis process will dissolve out during operation. Resins with low crosslinking degree and high content of active groups tend to dissolve more easily.
The present invention discloses a method for refining starch sugar solution, which comprises first introducing the starch sugar solution from one end of a separation column with a fixed phase of cation exchange resin into the separation column, so that the metal cations contained in the starch sugar solution undergo ion exchange with the cation exchange resin to obtain solution A; introducing solution A from one end of a separation column with a fixed phase of anion exchange resin into the separation column, so that the silicon compounds contained in solution A undergo ion exchange with the anion exchange resin, and obtaining a refined starch sugar solution from the other end of the separation column with the anion exchange resin, wherein the cation exchange resin is a Na type cation exchange resin and the anion exchange resin is an OH type anion exchange resin.
