Wuhai cation exchange resin 0017

An ion exchange resin containing a large amount of hydrophilic groups, i.e., swelling in contact with water. When the resin in the ion conversion, such as cationic resin into the h na, anion resin into the cl- oh-, are due to the increase of the ion diameter swell, increasing the volume of the resin. Typically, the expansion of the low degree of cross-linking resin is large. In the design of the ion exchange unit, it must take into account the expansion of the resin, the resin in order to adapt to changes in production volume runtime resin ion conversion occurs. Durability folding resin particles using metastasis, friction, expansion and contraction and other changes, after long-term use of a small amount of the loss and fragmentation, so the resin must have high mechanical strength and abrasion resistance. Typically, a low degree of cross-linking resins easily broken, but the durability of the resin is more important to decide on the extent and intensity of uniform cross-linked structure. As macroporous resin with a high degree of crosslinking who, structural stability, the ability of repeated regeneration.
