Abstract: A hierarchical porous polymeric material and its preparation method in the field of porous polymeric materials provided. The preparation method comprises: (1) mixing hydrophobic silica particles, an initiator, a polymerizable monomer, a crosslinking agent, a co-crosslinking agent and a pore-forming agent together, uniformly stirring to obtain a reaction mixture; (2) adding water into the reaction mixture and stirring until a gel emulsion is formed; and (3) carrying out staged thermal polymerization on the gel emulsion to obtain the hierarchical porous polymeric material. The present application can effectively regulate and control the contents and sizes of pores and throats, and obtain a material with hierarchical micro-porous structures. The good heat transfer and zero explosion in the polymerization process enable high product qualification rate. The wet material has rich pores, small resistance in mass transfer process and fast drying rate.

Abstract: The present disclosure discloses a quickly dismantlable floor member and a spliced floor, to solve the technical problem that the conventional floor members cannot be dismantled conveniently for repairing and replacement. The quickly dismantlable floor member is of a tetragon shape, a lateral face of a first side of the quickly dismantlable floor member is provided with an automatic latch, the automatic latch comprises a locking head, the locking head is retractable, and the locking head is able to, after the quickly dismantlable floor member is installed, join with an neighboring conventional floor member. The spliced floor employs three or more quickly dismantlable floor members.

Abstract: A collection apparatus for storing prolate photos belongs to the technical field of cultural relic protection equipment and includes multiple drawable arched drawing-type plates disposed in the cabinet, which enables the prolate photos to be fully flattened without repeated and memory curling. At the same time, a magnetic plating board is embedded in the bottom of every arched drawing-type plate, and a plurality of soft magnetic strips are placed on the surface of every arched drawing-type plate, and the magnetic attraction is formed between the magnetic plating board and the soft magnetic strip for fixing the prolate photos. As a result, the collection apparatus is reasonable in design and convenient to use, and is able to durably and stably protect prolate historical photos.
