  • Patent number: 11993541
    Abstract: The present invention discloses a multitype-adsorptive-group polycarboxylic acid water-reducing agent, consisting of 30-60 wt % of a macromolecule with multitype-adsorptive groups and water, the macromolecule with multitype-adsorptive groups has a polyethylene glycol side chain, and adsorption groups of the polymer backbone include a carboxylic acid group, a sulfonic acid group and a phosphoric acid group, the phosphoric acid group being linked to the backbone of the macromolecule with multitype-adsorptive groups by nucleophilic addition. The water-reducing agent of the present invention has significantly improved adaptability to different cements and aggregates while maintaining a high water reduction efficiency, compared with the conventional polycarboxylic acid water-reducing agent agent. It has a good water reducing efficiency in many different grades of cement, as well as a better resistance to aggregates containing more impurities such as machine-made sand.

  • Publication number: 20220148141
    Abstract: An image processing method includes determining a format of first image data; determining a first interface mode that is currently used, where the first interface mode is determined when the processing device establishes physical connections with a display device, and the format of the first image data format is not supported by the first interface mode; and processing the first image data based on the first interface mode to generate second image data, where a format of the second image data is supported by the first interface mode. Image data will be processed when an image format of the image data is not supported by the first interface mode.
