Abstract

A fine-cutting apparatus for hydrogels is disclosed. The fine-cutting apparatus for hydrogels according to an embodiment of the present invention comprises: a first barrel body extending in a first direction and having a first transfer space in which a hydrogel is transferred; a first transfer unit installed in the first barrel body to transfer the hydrogel in the first transfer space; a second barrel body installed on a side of the first barrel body and having a second transfer space which is connected to the first transfer space and extends in a second direction intersecting the first direction; a second transfer unit installed in the second barrel body to transfer the hydrogel in the second transfer space; a cutter member installed on the second barrel body to crush the hydrogel transferred by the second transfer unit; and a perforated plate for discharging hydrogel particles crushed by the cutter member to the outside of the second barrel body.

Description

technical field [0001] The present invention relates to superabsorbent polymer hydrogel shredding devices for uniformly shred hydrogels. Background technique [0002] Superabsorbent polymers (SAP) represent synthetic polymer materials that have the function of absorbing 500 to 1000 times their own weight in water, and their manufacturers call them superabsorbent materials (SAM) or absorbent gelling materials ( AGM). Superabsorbent polymers started to be commercialized as menstrual products, and they are currently widely used as hygiene products such as disposable diapers, soil remediation agents for gardening, water-stopping materials for public works, sheets for seedlings, fresh-keeping agents in the food distribution field, and Steaming material. [0003] Methods for producing the above-mentioned superabsorbent polymer include a method based on reverse phase suspension polymerization and a method based on solution polymerization. Inverse suspension polymerization is dis...
