Latest Patents

Shifu Sun holds a patent for a "Sustained release grouting material with its preparation method and application." This invention discloses a sustained release grouting material that comprises a water swelling core and a water-soluble sustained release coating. The water swelling core is composed of bentonite, superabsorbent polymer (SAP), and xanthan gum, which is granulated using a disc granulator that relies on the cohesiveness of xanthan gum. The water-soluble sustained-release coating is prepared by mixing water-soluble starch, polyvinyl alcohol, poloxamer, lubricant, and plasticizer with deionized water to create a film-forming solution. This solution is then coated onto the water-absorbing expansion core using a coating machine. The invention allows for the controllable water absorption onset time of the expansion core by adjusting the coating thickness through the mass ratio of the coating film-forming liquid to the core particles.
