Problems solved by technology

[0005] In this case, since the liquid level of the aqueous solution is unevenly formed due to hot air and the polymerization is performed in a state where the liquid level of the aqueous solution is uneven, the height of the polymer obtained after the polymerization also becomes uneven
As a result, there is a problem that one side of the precutter is overloaded when the polymer is crushed later by the precutter
In addition, there is a problem that it is not easy to perform venting in the polymerization reactor

Abstract

The present invention relates to an apparatus for manufacturing a high absorbent resin, and a method for manufacturing a high absorbent resin using the same. The apparatus for a high absorbent resin according to the present invention comprises: a belt which is installed over and between two or more rotary shafts and is movable in a predetermined direction by the rotation of the rotary shafts; a supplying unit for injecting a monomer composition to the belt; and a cover which is formed to surround the belt and from one side of which to the other side of which the belt passes through, wherein the belt comprises a horizontal bottom surface and lateral jaws provided at both ends of the belt at 30-70 degrees with respect to the bottom surface, and the cover comprises a heat inlet for supplying heat into the cover.

Description

technical field [0001] The present invention relates to a method for producing superabsorbent polymers and an apparatus for producing superabsorbent polymers using said method. Background technique [0002] A superabsorbent polymer (SAP) is a synthetic polymer material having a function of absorbing moisture 500 to 1000 times its weight, and is variously named superabsorbent material (SAM), depending on the developer, Absorbent gel material (absorbent gel material, AGM) and the like. Since it was put into practical use, this superabsorbent polymer has been widely used as a material in the following fields: water retaining agent for soil, waterstop for civil engineering and construction, Sheets for growing seedlings, and commodities for physical distribution and hygiene products, such as baby diapers. [0003] As a method of producing a superabsorbent polymer, reverse phase suspension polymerization (reverse phase suspension polymerization), aqueous solution polymerization ...
