METHOD FOR MANUFACTURING A WATER-ABSORBING RESIN |
摘要 |
<p>The disclosed continuous manufacturing method for a water-absorbing resin includes a plurality of connected continuous steps. Said method includes: a polymerization step in which an unsaturated monomer in an aqueous solution is polymerized; a drying step in which a water-containing cross-linked granular polymer gel, obtained in a microgranulation step during or after polymerization, is dried; a post-drying pulverization step; a post-drying sorting step; and a surface-treatment step, after the sorting step, in which a water-absorbing resin powder is subjected to a surface treatment. Said method is characterized in that, with some of the above steps kept running, the other steps are halted, and subsequently all steps are restarted.</p> |
