Latest Patents

Zhijie Wen's latest patents include 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. 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, allowing for controllable water absorption onset times.

Another notable patent is the "Underground gasifier pre-control structure, gasifier and gasification method." This invention includes a flame retardant injection system designed to enhance the safety and efficiency of underground gasification processes. The system features a flame retardant injection shaft pipe channel drilled from the ground to a coal seam, along with multiple flame retardant injection channels strategically placed around the gasifier. This innovative approach helps to create a wet coal wall in the coal seam, effectively controlling the spread of the gasifier.
